Temos o pracer de comunicarvos que do 16 ao 29 de outubro Pin Biotranslab, Casa do Río e The Foundry establece unha colaboración para levar a cabo o evento Eco (i) Logic Queer Energy harvesting. O proxecto é posible grazas ao apoio de GOSH, unha rede para desenvolver e difundir proxectos baseados en hardware de código aberto para a ciencia. '''Eco (i) Logic Queer Recollida de enerxía''' O evento ten como obxectivo abordar a falta de mulleres, queer, trans e diversidade nos ámbitos tecnolóxicos en xeral e do hacking máis concretamente. Pero aínda máis, pretende crear unha comunidade que avalía criticamente as narrativas hexemónicas arredor das tecnoloxías, os aspectos de modernidade dos seus supostos occidentais subliñados e as súas inflexións capitalistas inherentes, entre outros. O obxectivo principal do evento é desenvolver kits que se centren na interacción co medio natural no ámbito da enerxía.. o obxectivo principal pasa pola captación de enerxía do medio natural, a través dos aeroxeradores. Estes kits de enerxía serán escalables e poderán utilizarse tanto como material pedagóxico como para instalar centrais eléctricas específicas do sitio en diferentes sitios tamén. Este traballo ten un compoñente contrainfraestrutural: unha posible consecuencia sería capacitar ás persoas para xerar a súa propia enerxía en lugar de depender de grandes empresas e moitas veces extractivas. <br />
<br />
== Introdución e valores do proceso == <br />
<br />
Aquí comeza a documentación do longo proceso de creación de prototipos do modelo Hugh Piggott The Piggott Turbine - Wind Empowerment dunha turbina eólica de código aberto. Estivemos cambiando un pouco os obxectivos do evento, pasando de desenvolver pequenos kits para ir a construír o aeroxerador de 2 m de tamaño real para proporcionar enerxía ás áreas rexionais rurais nas que estabamos traballando. Nese evento concreto estivemos traballando en The Foundry un bonito proxecto e asociación que instalamos no norte de GaliZA ao noroeste de España. Durante o evento activáronse moitas cousas entre os realizadores e os visitantes; En xeral foi unha experiencia marabillosa chea de cousas novas que estudar, aprender, facer e comprender xuntos. Escollemos este modelo porque estaba cheo de capas de interese nos niveis de aprendizaxe, comprensión e elaboración, aquí algúns niveis mesturados con capas: en primeiro lugar é un dos que é '''de código aberto''' ou polo menos ten a opción de acceder á documentación completa. realmente '''ricos a nivel pedagóxico''', realmente estivemos aprendendo a través da construción completa do propio xerador, sobre moitos temas como: <br />
<br />
* electromagnetismo *matemáticas * xeometría * electrónica * AC-DC *soldadura * talla en madeira * escultura e fundición de pezas e moito máis que foi alcanzando a través do agradable proceso de ler, aprender e construír xuntos.<br />
<br />
== Glosario == <br />
* '''AC-'''Corrente alterna producida polo alternador. Todos os fíos: palabra estadounidense para varilla ou tachuelas "roscadas" ou "hiladas".<br />
* '''Interruptor de freo''' - Interruptor usado para curtocircuitar os cables do alternador para que se pare.<br />
* '''Catalizador''' - Un produto químico usado para facer sólido o conxunto de resinas de poliéster. O catalizador reacciona co "acelerador" xa presente na mestura de resina. A calor de reacción establece o poliéster.<br />
* '''Cavalier''' - Unha marca de coche. O cavalier no Reino Unido non é o mesmo que o Cavalier nos EUA, pero ambos teñen cubos de roda útiles.<br />
* '''DC - corrente continua''' cun lado positivo e outro negativo, como nos circuítos de batería.<br />
* '''Diámetro''' - A distancia dun lado a outro dun círculo. O ancho dun disco no medio.<br />
* '''Fase''' - O tempo da alternancia cíclica da tensión nun circuíto. As diferentes fases alcanzarán o pico en diferentes momentos.<br />
* '''Poliéster''' - Un tipo de resina utilizada no traballo de fibra de vidro. Tamén apto para facer fundicións.<br />
* '''Potencia''' - a taxa de entrega de enerxía<br />
* '''Rectifier''' - Un dispositivo semicondutor que converte AC en DC para cargar a batería.<br />
* '''Raíz''' - A parte máis ancha da lámina preto do cubo no centro do rotor.<br />
* '''Rotor''' - Unha parte xiratoria. Os rotores de imáns son os discos de aceiro que transportan os imáns máis alá do estator. As palas do rotor son a "hélice" impulsado polo vento e impulsando os rotores magnéticos.<br />
* '''Soldadura''': un método para facer conexións eléctricas entre fíos usando un 'ferro' quente e recubrindo todo con soldadura fundida.<br />
* '''Arrastre''' - Forza que exerce o vento sobre un obxecto. O arrastre é paralelo á dirección do vento no obxecto. (ver Ascensor)<br />
* '''Estator''' - Un conxunto de bobinas incrustadas nunha lousa de resina para formar parte do alternador. Os imáns inducen unha tensión nas bobinas e podemos utilizala para cargar unha batería. * '''Gota''': úsase aquí para describir unha determinada medida da forma da lámina dun muíño de vento. A "caída" afecta o ángulo de a lámina ao vento. Monómero de estireno - Un disolvente con cheiro desagradable na mestura de resina de poliéster.<br />
* '''Flux''' - As 'cousas' do magnetismo. Semellante á "corrente" na electricidade. Pódese visualizar como "liñas" que saen dun polo e volvendo ao outro.<br />
* '''Furling''' - Unha acción protectora que reduce a exposición a ventos violentos ao enfrontar as aspas lonxe delas.<br />
* '''Jig''' - Un dispositivo usado para manter os imáns no seu lugar antes de colocalos na resina.<br />
* '''Borde de ataque''' - O bordo dunha lámina que golpearía un obxecto colocado no seu camiño cando o rotor xira.<br />
* '''Elevación''' - Forza que exerce o vento sobre un obxecto. A sustentación está en ángulo recto coa dirección do vento no obxecto. (ver Arrastre)<br />
* '''Molde''' - Un recipiente con forma no que se forman fundicións de resina. O molde pódese descartar despois de que a fundición se fixera.<br />
* '''Multímetro''' - Un instrumento de proba eléctrico versátil, usado para medir tensión, corrente e outros parámetros.<br />
* '''Neodimio''' - O nome dado a un tipo de imán permanente que contén neodimio, ferro e boro. Estes imáns son moi fortes e cada vez máis barato.<br />
* '''Offset''' - Unha posición excéntrica, descentrada.<br />
* '''Po de talco'''- Un recheo en po barato que se usa para espesar a resina e retardar a súa reacción (evitar que se sobrequente).<br />
* '''Cola''': unha veleta que se sobresae montada nunha pluma na parte traseira do muíño de vento que se usa para dirixila ou fóra do vento automaticamente.<br />
* '''Tap''' - unha ferramenta para facer rosca dentro dos buratos para poder colocar un parafuso no burato.<br />
* '''Empuxe''' - A forza do vento que empurra a máquina cara atrás.<br />
* '''Torre''' - O mastro que soporta o muíño de vento.<br />
* '''Bordo posterior''': o bordo da lámina máis afastado do bordo de ataque. O bordo de saída está afiado, para liberar o paso aire sen turbulencias.<br />
* '''Cuñas''': pezas cónicas de madeira que se usan para aumentar o grosor da lámina e aumentar o seu ángulo co vento preto da raíz.<br />
* '''Peza de traballo''' - A peza de madeira ou metal que se está a dar forma no taller.<br />
* '''Colamento de guiñada''': o xiro da parte superior da torre na que está montado o muíño de vento. O rodamento de guiñada permite que o muíño se enfronte ao vento.<br />

. == O espazo == <br />
<br />
=== A fundición === <br />
<br />
A Fundición é unha organización sen ánimo de lucro con sede nunha aldea GaliZA anteriormente abandonada. Funciona tanto como residencia como como espazo de proxecto. Subscríbese aos ideais de autoorganización e ten os seguintes tres obxectivos: <br />
1. Organizar actividades no ámbito das artes, as ciencias e as humanidades fóra das institucións tradicionais, centradas no discurso crítico.<br />
2. Promover o intercambio de ideas e a colaboración intelectual fóra das limitacións impostas polo Estado e o mercado.<br />
3. Aumentar a autosuficiencia, a sustentabilidade e a concienciación co medio ambiente utilizando a tecnoloxía axeitada e o código aberto como principais recursos. Tendo en conta este contexto, o noso obxectivo é reforzar a capacidade de xerar redes que flúen do contexto rural ao urbano apoiando os intercambios non xerarquizados e democráticos de coñecementos e prácticas que permitan modelos novos e sostibles no contexto rural. Segundo iso consideramos que o novo creativo transdisciplinar dos sectores nos que estamos enredados poden ter un impacto enorme e positivo na creación deste novo paradigma.<br />
https://bravosfoundry.com/ <br />
Ademais, hai un foco temático na transdisciplinariedade, o transfeminismo e o poshumanismo. Aínda que este enfoque non é axeitadamente comprendido por categorías políticas identitarias como a raza ou o xénero, esperamos que leve á subversión das estruturas hexemónicas inscritas nos binarismos que sosteñen moitas destas categorías. O noso interese reside no desenvolvemento de ferramentas e tecnoloxías que subvertan as estruturas contemporáneas de dominación, explotación e marxinación, non nas que a reproducen. Buscamos desenvolver un entorno máis sostible abrindo as nosas prácticas baseadas nun marco de cultura libre, xerando redes e interese ao seu redor, posibilitando un fluxo de intercambio de innovación entre sectores creativos centrados na revalorización dos contextos rurais e do seu patrimonio de coñecemento. <br />

=== '''Sección 2, implica a construción de pezas do '''alternador''' utilizando os dispositivos da sección 1.''' === <br />
<br />
'''Alternador''' Cada rotor magnético é un disco de aceiro con 12 imáns colocados sobre el e colocados en resina. Os imáns son cada un de 50 x 50 x 20 mm, e só caben no disco. A idea é conseguir a máxima cantidade de fluxo nun espazo determinado. A turbina funciona a 650 rpm para unha saída de 400 W, polo que a forza centrífuga sobre os imáns é 60 veces a forza da gravidade. Para evitar que saian voando, hai que reforzar a fundición de resina. Un cable de aceiro inoxidable colócase arredor da parte exterior dos imáns para manter a fundición xunta a altas revolucións por minuto. Usamos inoxidable porque non é magnético, ou polo menos menos magnético que un cable de aceiro normal. Enrolarás as bobinas que producen a potencia de saída e fundirase en resina para formar un estator entre os dous rotores magnéticos. <br />

<br />
Paso - Xerador, rotor: Preparación do disco metálico. fíxose a máquina na tenda [[File:prod05.jpg|200px]] <br />
Paso - Xerador, rotor: Preparación do cubo da roda. <br />
[[File:frame10.jpg|200px]] '''O cubo da roda''' Podes atopar un cubo de roda traseira de coche usado (Golf, Toyota, etc.) que teña un xeito sinxelo engade o eixe ou, alternativamente, compre un cubos de remolque en liña novos a baixo custo. PCD ou "diámetro do círculo de paso" é o diámetro do círculo do patrón do burato no cubo, e normalmente este será de 100 mm para un cubo de roda de coche, ou de 4 polgadas para un cubo de remolque. Os hubs dos coches poden ter un tambor de freo que non precisa. Isto pódese eliminar usando a disco de corte nunha moedora. O enfoque máis sinxelo é facer catro cortes rectos ao redor os catro orificios na parte frontal, deixando unha superficie cadrada na que se monta o imán rotores. Estas fotos mostran un cubo de roda traseira de golf: primeiro se corta o tambor de freo e a continuación, o cubo acabado despois de cortar o tambor. Un típico cubo de coche de roda traseira con a brida no extremo traseiro do eixe do tronco que se pode reutilizar para montalo. Os cubos de remolque, por outra banda, son de calidade bastante básica, e os rodamentos tamén poden ser barato para uso a longo prazo, pero son artigos facilmente dispoñibles que se poden mercar en liña como novo. Os debuxos que aparecen a continuación (de autow.com) mostran un concentrador e un stub típicos eixe que se compran por separado. Debe estar preparado para substituír os rodamentos por unha marca nomeada (como SKF). É fácil de substituír os conos e rolos internos, pero hai que golpear as capas exteriores suavemente fóra do cubo cunha deriva adecuada. Mantéñaos rectos tocando uniformemente lados opostos e teña coidado de non raiar o asento. Paso - Xerador, rotor: <br />

=== Sección 4, implica o desexo das palas e a soldadura da base para o xerador de turbina. === <br />
<br />
4.1 Fabricación das láminas O coitelo é útil para anacos máis grosos de madeira e para cortar nun oco. Pode facer un bo traballo suave da raíz da lámina, mentres que o avión funcionará mellor onde necesitas un acabado moi recto. <br />
<br />
'''Marcando as estacións''' Coloque a folla co seu mellor bordo cara a vostede na súa superficie superior. Isto en realidade convértese na parte traseira ou "abaixo" da lámina acabada. (A maior parte do lado dianteiro ou de barlovento debe ser cortado, polo que hai defectos neste lado inferior non son importantes.) A raíz da folla estará á túa dereita, a punta á esquerda, a 1000 mm da raíz (preto do extremo esquerdo). Mide dende a raíz e marca catro estacións. Estación A a 75 mm Estación B a 150 mm Estación C a 500 mm A punta a 1000 mm. En cada estación debuxa unha liña ao redor da peza usando un cadrado. <br />
<br />
[[File:01tur.jpeg|400px]] <br />
<br />
'''Afilando a folla''' O ancho da folla diminúe desde o tamaño completo na estación C ata 55 mm de ancho na estación punta. Marque o ancho da punta de 55 mm, medindo dende o lado do bordo de ataque. Debuxa unha liña aínda que a túa marca ao lado do bordo posterior na estación C e corta unha peza triangular así como para conseguir a forma cónica correcta para a folla. Calquera nós no triangular o corte non importa xa que esta peza é descartada. Tenta facer este corte "cadrado", perpendicular á superficie posterior da lámina. Podes facelo cunha serra circular ou cortando e afeitando transversalmente como se describe arriba.<br />
<br />
[[File:02tur.jpeg|400px]] <br />
<br />
'''Marcando os bordos de entrada e de saída''' O seguinte paso é cortar a cara de barlovento da lámina. Esta cara está definida polo liñas de bordo de ataque e de saída da lámina. Estas liñas deben estar marcadas con referencia á cara posterior da madeira que estivo máis arriba na anterior operación. Darlle a volta á madeira. Comeza trazando dúas liñas diagonais entre as estacións A e B na parte dianteira ou a barlovento (ver máis abaixo). Un está na cara frontal e o outro na cara o bordo de saída que agora está cara a ti. <br />
<br />
[[File:03tur.jpeg|400px]] <br />
<br />
<br />
<br />
<br />
<br />
<br />
Agora debuxa a liña do bordo de ataque como se mostra a continuación, desde a estación B, ata 16 mm (desde atrás) na estación C, e despois continúa ata a punta en 7 mm de atrás.<br />
<br />
[[File:04tur.jpeg|400px]]<br />
<br />
(Este debuxo non mostra o bit extra máis aló da punta que pode quedar na súa peza de traballo real). As medidas resúmense nesta táboa a continuación. As alturas son dende a parte traseira folla que despois descansará no banco. Elimina a madeira por encima desta altura. "Cheo" refírese ao grosor total da peza de madeira orixinal que está a usar.<br />
<br />
<br />
<br />
[[File:05tur.jpeg|400px]]<br />
<br />
'''O rastro''' A liña do bordo posterior comeza na parte inferior da liña diagonal na estación B e sobe a 5 mm en C, continuando a 5 mm ata a punta. Esta vista abaixo mostra a madeira xa eliminado entre as dúas liñas para formar a cara barlovento da pala.<br />
<br />
<br />
<br />
[[File:06tur.png|400px]]<br />
<br />
Esculpe esta cara de barlovento plana entre as dúas liñas. Coida que os bordos estean recto, seguindo as liñas. A mellor ferramenta para usar para rematar a parte exterior do a lámina é un plano, para dar un acabado suave e recto. Quizais necesites traballar no avión 45 graos coa peza de traballo, deslizando parcialmente cara aos lados, para formar a forma oca en estación C. Este paso complétase cando podes colocar unha regra pola cara entre os principais e liñas de bordo de saída e non hai "xoroba" no medio. Encha calquera chip ou pequeno ocos con recheo de madeira. Se hai algún erro grave, ou k grande non que se debilitan a folla, entón pode ter que ser descartada. Comprobe a "caída" usando un nivel como referencia. Suxeitar a madeira para que a parte da raíz sitúase nivelado e mida a diferenza de nivel entre os bordos de entrada e de saída. A diferenza ou "caída" debe ser de 11 mm no punto medio de 500 mm e de 2 mm no punta.<br />

'''Eco (i) Logic Queer Recollida de enerxía''' O evento ten como obxectivo abordar a falta de mulleres, queer, trans e diversidade nos ámbitos tecnolóxicos en xeral e do hacking máis concretamente. Pero aínda máis, pretende crear unha comunidade que avalía criticamente as narrativas hexemónicas arredor das tecnoloxías, os aspectos de modernidade dos seus supostos occidentais subliñados e as súas inflexións capitalistas inherentes, entre outros. O obxectivo principal do evento é desenvolver kits que se centren na interacción co medio natural no ámbito da enerxía.. o obxectivo principal pasa pola captación de enerxía do medio natural, a través dos aeroxeradores. Estes kits de enerxía serán escalables e poderán utilizarse tanto como material pedagóxico como para instalar centrais eléctricas específicas do sitio en diferentes sitios tamén. Este traballo ten un compoñente contrainfraestrutural: unha posible consecuencia sería capacitar ás persoas para xerar a súa propia enerxía en lugar de depender de grandes empresas e moitas veces extractivas. <br />
<br />
== Introdución e valores do proceso == <br />
<br />
Aquí comeza a documentación do longo proceso de creación de prototipos do modelo Hugh Piggott The Piggott Turbine - Wind Empowerment dunha turbina eólica de código aberto. Estivemos cambiando un pouco os obxectivos do evento, pasando de desenvolver pequenos kits para ir a construír o aeroxerador de 2 m de tamaño real para proporcionar enerxía ás áreas rexionais rurais nas que estabamos traballando. Nese evento concreto estivemos traballando en The Foundry un bonito proxecto e asociación que instalamos no norte de GaliZA ao noroeste de España. Durante o evento activáronse moitas cousas entre os realizadores e os visitantes; En xeral foi unha experiencia marabillosa chea de cousas novas que estudar, aprender, facer e comprender xuntos. Escollemos este modelo porque estaba cheo de capas de interese nos niveis de aprendizaxe, comprensión e elaboración, aquí algúns niveis mesturados con capas: en primeiro lugar é un dos que é '''de código aberto''' ou polo menos ten a opción de acceder á documentación completa. realmente '''ricos a nivel pedagóxico''', realmente estivemos aprendendo a través da construción completa do propio xerador, sobre moitos temas como: <br />
<br />
* electromagnetismo *matemáticas * xeometría * electrónica * AC-DC *soldadura * talla en madeira * escultura e fundición de pezas e moito máis que foi alcanzando a través do agradable proceso de ler, aprender e construír xuntos.<br />
<br />
== Glosario == <br />
* '''AC-'''Corrente alterna producida polo alternador. Todos os fíos: palabra estadounidense para varilla ou tachuelas "roscadas" ou "hiladas".<br />
* '''Interruptor de freo''' - Interruptor usado para curtocircuitar os cables do alternador para que se pare.<br />
* '''Catalizador''' - Un produto químico usado para facer sólido o conxunto de resinas de poliéster. O catalizador reacciona co "acelerador" xa presente na mestura de resina. A calor de reacción establece o poliéster.<br />
* '''Cavalier''' - Unha marca de coche. O cavalier no Reino Unido non é o mesmo que o Cavalier nos EUA, pero ambos teñen cubos de roda útiles.<br />
* '''DC - corrente continua''' cun lado positivo e outro negativo, como nos circuítos de batería.<br />
* '''Diámetro''' - A distancia dun lado a outro dun círculo. O ancho dun disco no medio.<br />
* '''Fase''' - O tempo da alternancia cíclica da tensión nun circuíto. As diferentes fases alcanzarán o pico en diferentes momentos.<br />
* '''Poliéster''' - Un tipo de resina utilizada no traballo de fibra de vidro. Tamén apto para facer fundicións.<br />
* '''Potencia''' - a taxa de entrega de enerxía<br />
* '''Rectifier''' - Un dispositivo semicondutor que converte AC en DC para cargar a batería.<br />
* '''Raíz''' - A parte máis ancha da lámina preto do cubo no centro do rotor.<br />
* '''Rotor''' - Unha parte xiratoria. Os rotores de imáns son os discos de aceiro que transportan os imáns máis alá do estator. As palas do rotor son a "hélice" impulsado polo vento e impulsando os rotores magnéticos.<br />
* '''Soldadura''': un método para facer conexións eléctricas entre fíos usando un 'ferro' quente e recubrindo todo con soldadura fundida.<br />
* '''Arrastre''' - Forza que exerce o vento sobre un obxecto. O arrastre é paralelo á dirección do vento no obxecto. (ver Ascensor)<br />
* '''Estator''' - Un conxunto de bobinas incrustadas nunha lousa de resina para formar parte do alternador. Os imáns inducen unha tensión nas bobinas e podemos utilizala para cargar unha batería. * '''Gota''': úsase aquí para describir unha determinada medida da forma da lámina dun muíño de vento. A "caída" afecta o ángulo de a lámina ao vento. Monómero de estireno - Un disolvente con cheiro desagradable na mestura de resina de poliéster.<br />
* '''Flux''' - As 'cousas' do magnetismo. Semellante á "corrente" na electricidade. Pódese visualizar como "liñas" que saen dun polo e volvendo ao outro.<br />
* '''Furling''' - Unha acción protectora que reduce a exposición a ventos violentos ao enfrontar as aspas lonxe delas.<br />
* '''Jig''' - Un dispositivo usado para manter os imáns no seu lugar antes de colocalos na resina.<br />
* '''Borde de ataque''' - O bordo dunha lámina que golpearía un obxecto colocado no seu camiño cando o rotor xira.<br />
* '''Elevación''' - Forza que exerce o vento sobre un obxecto. A sustentación está en ángulo recto coa dirección do vento no obxecto. (ver Arrastre)<br />
* '''Molde''' - Un recipiente con forma no que se forman fundicións de resina. O molde pódese descartar despois de que a fundición se fixera.<br />
* '''Multímetro''' - Un instrumento de proba eléctrico versátil, usado para medir tensión, corrente e outros parámetros.<br />
* '''Neodimio''' - O nome dado a un tipo de imán permanente que contén neodimio, ferro e boro. Estes imáns son moi fortes e cada vez máis barato.<br />
* '''Offset''' - Unha posición excéntrica, descentrada.<br />
* '''Po de talco'''- Un recheo en po barato que se usa para espesar a resina e retardar a súa reacción (evitar que se sobrequente).<br />
* '''Cola''': unha veleta que se sobresae montada nunha pluma na parte traseira do muíño de vento que se usa para dirixila ou fóra do vento automaticamente.<br />
* '''Tap''' - unha ferramenta para facer rosca dentro dos buratos para poder colocar un parafuso no burato.<br />
* '''Empuxe''' - A forza do vento que empurra a máquina cara atrás.<br />
* '''Torre''' - O mastro que soporta o muíño de vento.<br />
* '''Bordo posterior''': o bordo da lámina máis afastado do bordo de ataque. O bordo de saída está afiado, para liberar o paso aire sen turbulencias.<br />
* '''Cuñas''': pezas cónicas de madeira que se usan para aumentar o grosor da lámina e aumentar o seu ángulo co vento preto da raíz.<br />
* '''Peza de traballo''' - A peza de madeira ou metal que se está a dar forma no taller.<br />
* '''Colamento de guiñada''': o xiro da parte superior da torre na que está montado o muíño de vento. O rodamento de guiñada permite que o muíño se enfronte ao vento.<br />

. == O espazo == <br />
<br />
=== A fundición === <br />
<br />
A Fundición é unha organización sen ánimo de lucro con sede nunha aldea GaliZA anteriormente abandonada. Funciona tanto como residencia como como espazo de proxecto. Subscríbese aos ideais de autoorganización e ten os seguintes tres obxectivos: <br />
1. Organizar actividades no ámbito das artes, as ciencias e as humanidades fóra das institucións tradicionais, centradas no discurso crítico.<br />
2. Promover o intercambio de ideas e a colaboración intelectual fóra das limitacións impostas polo Estado e o mercado.<br />
3. Aumentar a autosuficiencia, a sustentabilidade e a concienciación co medio ambiente utilizando a tecnoloxía axeitada e o código aberto como principais recursos. Tendo en conta este contexto, o noso obxectivo é reforzar a capacidade de xerar redes que flúen do contexto rural ao urbano apoiando os intercambios non xerarquizados e democráticos de coñecementos e prácticas que permitan modelos novos e sostibles no contexto rural. Segundo iso consideramos que o novo creativo transdisciplinar dos sectores nos que estamos enredados poden ter un impacto enorme e positivo na creación deste novo paradigma.<br />
https://bravosfoundry.com/ <br />
Ademais, hai un foco temático na transdisciplinariedade, o transfeminismo e o poshumanismo. Aínda que este enfoque non é axeitadamente comprendido por categorías políticas identitarias como a raza ou o xénero, esperamos que leve á subversión das estruturas hexemónicas inscritas nos binarismos que sosteñen moitas destas categorías. O noso interese reside no desenvolvemento de ferramentas e tecnoloxías que subvertan as estruturas contemporáneas de dominación, explotación e marxinación, non nas que a reproducen. Buscamos desenvolver un entorno máis sostible abrindo as nosas prácticas baseadas nun marco de cultura libre, xerando redes e interese ao seu redor, posibilitando un fluxo de intercambio de innovación entre sectores creativos centrados na revalorización dos contextos rurais e do seu patrimonio de coñecemento. <br />

=== '''Sección 2, implica a construción de pezas do '''alternador''' utilizando os dispositivos da sección 1.''' === <br />
<br />
'''Alternador''' Cada rotor magnético é un disco de aceiro con 12 imáns colocados sobre el e colocados en resina. Os imáns son cada un de 50 x 50 x 20 mm, e só caben no disco. A idea é conseguir a máxima cantidade de fluxo nun espazo determinado. A turbina funciona a 650 rpm para unha saída de 400 W, polo que a forza centrífuga sobre os imáns é 60 veces a forza da gravidade. Para evitar que saian voando, hai que reforzar a fundición de resina. Un cable de aceiro inoxidable colócase arredor da parte exterior dos imáns para manter a fundición xunta a altas revolucións por minuto. Usamos inoxidable porque non é magnético, ou polo menos menos magnético que un cable de aceiro normal. Enrolarás as bobinas que producen a potencia de saída e fundirase en resina para formar un estator entre os dous rotores magnéticos. <br />

<br />
Paso - Xerador, rotor: Preparación do disco metálico. fíxose a máquina na tenda [[File:prod05.jpg|200px]] <br />
Paso - Xerador, rotor: Preparación do cubo da roda. <br />
[[File:frame10.jpg|200px]] '''O cubo da roda''' Podes atopar un cubo de roda traseira de coche usado (Golf, Toyota, etc.) que teña un xeito sinxelo engade o eixe ou, alternativamente, compre un cubos de remolque en liña novos a baixo custo. PCD ou "diámetro do círculo de paso" é o diámetro do círculo do patrón do burato no cubo, e normalmente este será de 100 mm para un cubo de roda de coche, ou de 4 polgadas para un cubo de remolque. Os hubs dos coches poden ter un tambor de freo que non precisa. Isto pódese eliminar usando a disco de corte nunha moedora. O enfoque máis sinxelo é facer catro cortes rectos ao redor os catro orificios na parte frontal, deixando unha superficie cadrada na que se monta o imán rotores. Estas fotos mostran un cubo de roda traseira de golf: primeiro se corta o tambor de freo e a continuación, o cubo acabado despois de cortar o tambor. Un típico cubo de coche de roda traseira con a brida no extremo traseiro do eixe do tronco que se pode reutilizar para montalo. Os cubos de remolque, por outra banda, son de calidade bastante básica, e os rodamentos tamén poden ser barato para uso a longo prazo, pero son artigos facilmente dispoñibles que se poden mercar en liña como novo. Os debuxos que aparecen a continuación (de autow.com) mostran un concentrador e un stub típicos eixe que se compran por separado. Debe estar preparado para substituír os rodamentos por unha marca nomeada (como SKF). É fácil de substituír os conos e rolos internos, pero hai que golpear as capas exteriores suavemente fóra do cubo cunha deriva adecuada. Mantéñaos rectos tocando uniformemente lados opostos e teña coidado de non raiar o asento. Paso - Xerador, rotor: <br />

=== Sección 4, implica o desexo das palas e a soldadura da base para o xerador de turbina. === <br />
<br />
4.1 Fabricación das láminas O coitelo é útil para anacos máis grosos de madeira e para cortar nun oco. Pode facer un bo traballo suave da raíz da lámina, mentres que o avión funcionará mellor onde necesitas un acabado moi recto. <br />
<br />
'''Marcando as estacións''' Coloque a folla co seu mellor bordo cara a vostede na súa superficie superior. Isto en realidade convértese na parte traseira ou "abaixo" da lámina acabada. (A maior parte do lado dianteiro ou de barlovento debe ser cortado, polo que hai defectos neste lado inferior non son importantes.) A raíz da folla estará á túa dereita, a punta á esquerda, a 1000 mm da raíz (preto do extremo esquerdo). Mide dende a raíz e marca catro estacións. Estación A a 75 mm Estación B a 150 mm Estación C a 500 mm A punta a 1000 mm. En cada estación debuxa unha liña ao redor da peza usando un cadrado. <br />
[[File:01tur.jpeg|400px]] <br />
<br />
'''Afilando a folla''' O ancho da folla diminúe desde o tamaño completo na estación C ata 55 mm de ancho na estación punta. Marque o ancho da punta de 55 mm, medindo dende o lado do bordo de ataque. Debuxa unha liña aínda que a túa marca ao lado do bordo posterior na estación C e corta unha peza triangular así como para conseguir a forma cónica correcta para a folla. Calquera nós no triangular o corte non importa xa que esta peza é descartada. Tenta facer este corte "cadrado", perpendicular á superficie posterior da lámina. Podes facelo cunha serra circular ou cortando e afeitando transversalmente como se describe arriba.<br />
[[File:02tur.jpeg|400px]] <br />
<br />
'''Marcando os bordos de entrada e de saída''' O seguinte paso é cortar a cara de barlovento da lámina. Esta cara está definida polo liñas de bordo de ataque e de saída da lámina. Estas liñas deben estar marcadas con referencia á cara posterior da madeira que estivo máis arriba na anterior operación. Darlle a volta á madeira. Comeza trazando dúas liñas diagonais entre as estacións A e B na parte dianteira ou a barlovento (ver máis abaixo). Un está na cara frontal e o outro na cara o bordo de saída que agora está cara a ti. <br />
[[File:03tur.jpeg|400px]] <br />
<br />
<br />
<br />
<br />
<br />
<br />
Agora debuxa a liña do bordo de ataque como se mostra a continuación, desde a estación B, ata 16 mm (desde atrás) na estación C, e despois continúa ata a punta en 7 mm de atrás.<br />
<br />
[[File:04tur.jpeg|400px]]<br />
<br />
(Este debuxo non mostra o bit extra máis aló da punta que pode quedar na súa peza de traballo real). As medidas resúmense nesta táboa a continuación. As alturas son dende a parte traseira folla que despois descansará no banco. Elimina a madeira por encima desta altura. "Cheo" refírese ao grosor total da peza de madeira orixinal que está a usar.<br />
<br />
<br />
<br />
[[File:05tur.jpeg|400px]]<br />
<br />
'''O rastro''' A liña do bordo posterior comeza na parte inferior da liña diagonal na estación B e sobe a 5 mm en C, continuando a 5 mm ata a punta. Esta vista abaixo mostra a madeira xa eliminado entre as dúas liñas para formar a cara barlovento da pala.<br />
<br />
<br />
<br />
[[File:06tur.png|400px]]<br />
<br />
Esculpe esta cara de barlovento plana entre as dúas liñas. Coida que os bordos estean recto, seguindo as liñas. A mellor ferramenta para usar para rematar a parte exterior do a lámina é un plano, para dar un acabado suave e recto. Quizais necesites traballar no avión 45 graos coa peza de traballo, deslizando parcialmente cara aos lados, para formar a forma oca en estación C. Este paso complétase cando podes colocar unha regra pola cara entre os principais e liñas de bordo de saída e non hai "xoroba" no medio. Encha calquera chip ou pequeno ocos con recheo de madeira. Se hai algún erro grave, ou k grande non que se debilitan a folla, entón pode ter que ser descartada. Comprobe a "caída" usando un nivel como referencia. Suxeitar a madeira para que a parte da raíz sitúase nivelado e mida a diferenza de nivel entre os bordos de entrada e de saída. A diferenza ou "caída" debe ser de 11 mm no punto medio de 500 mm e de 2 mm no punta.<br />

''Pedagoxías do vento e das estrelas. As relacións sociais ás que (nunca estabamos destinados) a sobrevivir, tamén viven nos nosos corpos dolorosamente, e Audre Lorde non está aquí para lembrarnos esta lección, salvo na medida en que está presente no vento pedagóxico. Pero o vento é o noso mestre (74). -Alexis Pauline Gumbs'' do libro Mapping Queer Space(s) of Praxis and Pedagogy Editores: Elizabeth McNeil, James E. Wermers, Joshua O. Lunn'' <br />

Temos o pracer de comunicarvos que do 16 ao 29 de outubro Pin Biotranslab, Casa do Río e The Foundry establece unha colaboración para levar a cabo o evento Eco (i) Logic Queer Energy harvesting. O proxecto é posible grazas ao apoio de GOSH, unha rede para desenvolver e difundir proxectos baseados en hardware de código aberto para a ciencia. '''Eco (i) Logic Queer Recollida de enerxía''' O evento ten como obxectivo abordar a falta de mulleres, queer, trans e diversidade nos ámbitos tecnolóxicos en xeral e do hacking máis concretamente. Pero aínda máis, pretende crear unha comunidade que avalía criticamente as narrativas hexemónicas arredor das tecnoloxías, os aspectos de modernidade dos seus supostos occidentais subliñados e as súas inflexións capitalistas inherentes, entre outros. O obxectivo principal do evento é desenvolver kits que se centren na interacción co medio natural no ámbito da enerxía.. o obxectivo principal pasa pola captación de enerxía do medio natural, a través dos aeroxeradores. Estes kits de enerxía serán escalables e poderán utilizarse tanto como material pedagóxico como para instalar centrais eléctricas específicas do sitio en diferentes sitios tamén. Este traballo ten un compoñente contrainfraestrutural: unha posible consecuencia sería capacitar ás persoas para xerar a súa propia enerxía en lugar de depender de grandes empresas e moitas veces extractivas. <br />
<br />
== Introdución e valores do proceso == <br />
<br />
Aquí comeza a documentación do longo proceso de creación de prototipos do modelo Hugh Piggott The Piggott Turbine - Wind Empowerment dunha turbina eólica de código aberto. Estivemos cambiando un pouco os obxectivos do evento, pasando de desenvolver pequenos kits para ir a construír o aeroxerador de 2 m de tamaño real para proporcionar enerxía ás áreas rexionais rurais nas que estabamos traballando. Nese evento concreto estivemos traballando en The Foundry un bonito proxecto e asociación que instalamos no norte de GaliZA ao noroeste de España. Durante o evento activáronse moitas cousas entre os realizadores e os visitantes; En xeral foi unha experiencia marabillosa chea de cousas novas que estudar, aprender, facer e comprender xuntos. Escollemos este modelo porque estaba cheo de capas de interese nos niveis de aprendizaxe, comprensión e elaboración, aquí algúns niveis mesturados con capas: en primeiro lugar é un dos que é '''de código aberto''' ou polo menos ten a opción de acceder á documentación completa. realmente '''ricos a nivel pedagóxico''', realmente estivemos aprendendo a través da construción completa do propio xerador, sobre moitos temas como: <br />
<br />
* electromagnetismo *matemáticas * xeometría * electrónica * AC-DC *soldadura * talla en madeira * escultura e fundición de pezas e moito máis que foi alcanzando a través do agradable proceso de ler, aprender e construír xuntos.<br />
<br />
== Glosario == <br />
* '''AC-'''Corrente alterna producida polo alternador. Todos os fíos: palabra estadounidense para varilla ou tachuelas "roscadas" ou "hiladas".<br />
* '''Interruptor de freo''' - Interruptor usado para curtocircuitar os cables do alternador para que se pare.<br />
* '''Catalizador''' - Un produto químico usado para facer sólido o conxunto de resinas de poliéster. O catalizador reacciona co "acelerador" xa presente na mestura de resina. A calor de reacción establece o poliéster.<br />
* '''Cavalier''' - Unha marca de coche. O cavalier no Reino Unido non é o mesmo que o Cavalier nos EUA, pero ambos teñen cubos de roda útiles.<br />
* '''DC - corrente continua''' cun lado positivo e outro negativo, como nos circuítos de batería.<br />
* '''Diámetro''' - A distancia dun lado a outro dun círculo. O ancho dun disco no medio.<br />
* '''Fase''' - O tempo da alternancia cíclica da tensión nun circuíto. As diferentes fases alcanzarán o pico en diferentes momentos.<br />
* '''Poliéster''' - Un tipo de resina utilizada no traballo de fibra de vidro. Tamén apto para facer fundicións.<br />
* '''Potencia''' - a taxa de entrega de enerxía<br />
* '''Rectifier''' - Un dispositivo semicondutor que converte AC en DC para cargar a batería.<br />
* '''Raíz''' - A parte máis ancha da lámina preto do cubo no centro do rotor.<br />
* '''Rotor''' - Unha parte xiratoria. Os rotores de imáns son os discos de aceiro que transportan os imáns máis alá do estator. As palas do rotor son a "hélice" impulsado polo vento e impulsando os rotores magnéticos.<br />
* '''Soldadura''': un método para facer conexións eléctricas entre fíos usando un 'ferro' quente e recubrindo todo con soldadura fundida.<br />
* '''Arrastre''' - Forza que exerce o vento sobre un obxecto. O arrastre é paralelo á dirección do vento no obxecto. (ver Ascensor)<br />
* '''Estator''' - Un conxunto de bobinas incrustadas nunha lousa de resina para formar parte do alternador. Os imáns inducen unha tensión nas bobinas e podemos utilizala para cargar unha batería. * '''Gota''': úsase aquí para describir unha determinada medida da forma da lámina dun muíño de vento. A "caída" afecta o ángulo de a lámina ao vento. Monómero de estireno - Un disolvente con cheiro desagradable na mestura de resina de poliéster.<br />
* '''Flux''' - As 'cousas' do magnetismo. Semellante á "corrente" na electricidade. Pódese visualizar como "liñas" que saen dun polo e volvendo ao outro.<br />
* '''Furling''' - Unha acción protectora que reduce a exposición a ventos violentos ao enfrontar as aspas lonxe delas.<br />
* '''Jig''' - Un dispositivo usado para manter os imáns no seu lugar antes de colocalos na resina.<br />
* '''Borde de ataque''' - O bordo dunha lámina que golpearía un obxecto colocado no seu camiño cando o rotor xira.<br />
* '''Elevación''' - Forza que exerce o vento sobre un obxecto. A sustentación está en ángulo recto coa dirección do vento no obxecto. (ver Arrastre)<br />
* '''Molde''' - Un recipiente con forma no que se forman fundicións de resina. O molde pódese descartar despois de que a fundición se fixera.<br />
* '''Multímetro''' - Un instrumento de proba eléctrico versátil, usado para medir tensión, corrente e outros parámetros.<br />
* '''Neodimio''' - O nome dado a un tipo de imán permanente que contén neodimio, ferro e boro. Estes imáns son moi fortes e cada vez máis barato.<br />
* '''Offset''' - Unha posición excéntrica, descentrada.<br />
* '''Po de talco'''- Un recheo en po barato que se usa para espesar a resina e retardar a súa reacción (evitar que se sobrequente).<br />
* '''Cola''': unha veleta que se sobresae montada nunha pluma na parte traseira do muíño de vento que se usa para dirixila ou fóra do vento automaticamente.<br />
* '''Tap''' - unha ferramenta para facer rosca dentro dos buratos para poder colocar un parafuso no burato.<br />
* '''Empuxe''' - A forza do vento que empurra a máquina cara atrás.<br />
* '''Torre''' - O mastro que soporta o muíño de vento.<br />
* '''Bordo posterior''': o bordo da lámina máis afastado do bordo de ataque. O bordo de saída está afiado, para liberar o paso aire sen turbulencias.<br />
* '''Cuñas''': pezas cónicas de madeira que se usan para aumentar o grosor da lámina e aumentar o seu ángulo co vento preto da raíz.<br />
* '''Peza de traballo''' - A peza de madeira ou metal que se está a dar forma no taller.<br />
* '''Colamento de guiñada''': o xiro da parte superior da torre na que está montado o muíño de vento. O rodamento de guiñada permite que o muíño se enfronte ao vento.<br />

. == O espazo == <br />
<br />
=== A fundición === <br />
<br />
A Fundición é unha organización sen ánimo de lucro con sede nunha aldea GaliZA anteriormente abandonada. Funciona tanto como residencia como como espazo de proxecto. Subscríbese aos ideais de autoorganización e ten os seguintes tres obxectivos: <br />
1. Organizar actividades no ámbito das artes, as ciencias e as humanidades fóra das institucións tradicionais, centradas no discurso crítico.<br />
2. Promover o intercambio de ideas e a colaboración intelectual fóra das limitacións impostas polo Estado e o mercado.<br />
3. Aumentar a autosuficiencia, a sustentabilidade e a concienciación co medio ambiente utilizando a tecnoloxía axeitada e o código aberto como principais recursos. Tendo en conta este contexto, o noso obxectivo é reforzar a capacidade de xerar redes que flúen do contexto rural ao urbano apoiando os intercambios non xerarquizados e democráticos de coñecementos e prácticas que permitan modelos novos e sostibles no contexto rural. Segundo iso consideramos que o novo creativo transdisciplinar dos sectores nos que estamos enredados poden ter un impacto enorme e positivo na creación deste novo paradigma.<br />
https://bravosfoundry.com/ <br />
Ademais, hai un foco temático na transdisciplinariedade, o transfeminismo e o poshumanismo. Aínda que este enfoque non é axeitadamente comprendido por categorías políticas identitarias como a raza ou o xénero, esperamos que leve á subversión das estruturas hexemónicas inscritas nos binarismos que sosteñen moitas destas categorías. O noso interese reside no desenvolvemento de ferramentas e tecnoloxías que subvertan as estruturas contemporáneas de dominación, explotación e marxinación, non nas que a reproducen. Buscamos desenvolver un entorno máis sostible abrindo as nosas prácticas baseadas nun marco de cultura libre, xerando redes e interese ao seu redor, posibilitando un fluxo de intercambio de innovación entre sectores creativos centrados na revalorización dos contextos rurais e do seu patrimonio de coñecemento. <br />

=== '''Sección 2, implica a construción de pezas do '''alternador''' utilizando os dispositivos da sección 1.''' === <br />
<br />
'''Alternador''' Cada rotor magnético é un disco de aceiro con 12 imáns colocados sobre el e colocados en resina. Os imáns son cada un de 50 x 50 x 20 mm, e só caben no disco. A idea é conseguir a máxima cantidade de fluxo nun espazo determinado. A turbina funciona a 650 rpm para unha saída de 400 W, polo que a forza centrífuga sobre os imáns é 60 veces a forza da gravidade. Para evitar que saian voando, hai que reforzar a fundición de resina. Un cable de aceiro inoxidable colócase arredor da parte exterior dos imáns para manter a fundición xunta a altas revolucións por minuto. Usamos inoxidable porque non é magnético, ou polo menos menos magnético que un cable de aceiro normal. Enrolarás as bobinas que producen a potencia de saída e fundirase en resina para formar un estator entre os dous rotores magnéticos. <br />

=== Sección 3, implica a creación da parte do rotor do xerador: === <br />
<br />
Paso - Xerador, rotor: Preparación do disco metálico. fíxose a máquina na tenda [[File:prod05.jpg|200px]] <br />
Paso - Xerador, rotor: Preparación do cubo da roda. <br />
[[File:frame10.jpg|200px]] '''O cubo da roda''' Podes atopar un cubo de roda traseira de coche usado (Golf, Toyota, etc.) que teña un xeito sinxelo engade o eixe ou, alternativamente, compre un cubos de remolque en liña novos a baixo custo. PCD ou "diámetro do círculo de paso" é o diámetro do círculo do patrón do burato no cubo, e normalmente este será de 100 mm para un cubo de roda de coche, ou de 4 polgadas para un cubo de remolque. Os hubs dos coches poden ter un tambor de freo que non precisa. Isto pódese eliminar usando a disco de corte nunha moedora. O enfoque máis sinxelo é facer catro cortes rectos ao redor os catro orificios na parte frontal, deixando unha superficie cadrada na que se monta o imán rotores. Estas fotos mostran un cubo de roda traseira de golf: primeiro se corta o tambor de freo e a continuación, o cubo acabado despois de cortar o tambor. Un típico cubo de coche de roda traseira con a brida no extremo traseiro do eixe do tronco que se pode reutilizar para montalo. Os cubos de remolque, por outra banda, son de calidade bastante básica, e os rodamentos tamén poden ser barato para uso a longo prazo, pero son artigos facilmente dispoñibles que se poden mercar en liña como novo. Os debuxos que aparecen a continuación (de autow.com) mostran un concentrador e un stub típicos eixe que se compran por separado. Debe estar preparado para substituír os rodamentos por unha marca nomeada (como SKF). É fácil de substituír os conos e rolos internos, pero hai que golpear as capas exteriores suavemente fóra do cubo cunha deriva adecuada. Mantéñaos rectos tocando uniformemente lados opostos e teña coidado de non raiar o asento. Paso - Xerador, rotor: <br />

=== Sección 4, implica o desexo das palas e a soldadura da base para o xerador de turbina. === <br />
<br />
4.1 Fabricación das láminas O coitelo é útil para anacos máis grosos de madeira e para cortar nun oco. Pode facer un bo traballo suave da raíz da lámina, mentres que o avión funcionará mellor onde necesitas un acabado moi recto. <br />
<br />
'''Marcando as estacións''' Coloque a folla co seu mellor bordo cara a vostede na súa superficie superior. Isto en realidade convértese na parte traseira ou "abaixo" da lámina acabada. (A maior parte do lado dianteiro ou de barlovento debe ser cortado, polo que hai defectos neste lado inferior non son importantes.) A raíz da folla estará á túa dereita, a punta á esquerda, a 1000 mm da raíz (preto do extremo esquerdo). Mide dende a raíz e marca catro estacións. Estación A a 75 mm Estación B a 150 mm Estación C a 500 mm A punta a 1000 mm. En cada estación debuxa unha liña ao redor da peza usando un cadrado. <br />
[[File:01tur.jpeg|400px]] <br />
'''Afilando a folla''' O ancho da folla diminúe desde o tamaño completo na estación C ata 55 mm de ancho na estación punta. Marque o ancho da punta de 55 mm, medindo dende o lado do bordo de ataque. Debuxa unha liña aínda que a túa marca ao lado do bordo posterior na estación C e corta unha peza triangular así como para conseguir a forma cónica correcta para a folla. Calquera nós no triangular o corte non importa xa que esta peza é descartada. Tenta facer este corte "cadrado", perpendicular á superficie posterior da lámina. Podes facelo cunha serra circular ou cortando e afeitando transversalmente como se describe arriba.<br />
[[File:02tur.jpeg|400px]] <br />
<br />
'''Marcando os bordos de entrada e de saída''' O seguinte paso é cortar a cara de barlovento da lámina. Esta cara está definida polo liñas de bordo de ataque e de saída da lámina. Estas liñas deben estar marcadas con referencia á cara posterior da madeira que estivo máis arriba na anterior operación. Darlle a volta á madeira. Comeza trazando dúas liñas diagonais entre as estacións A e B na parte dianteira ou a barlovento (ver máis abaixo). Un está na cara frontal e o outro na cara o bordo de saída que agora está cara a ti. <br />
[[File:03tur.jpeg|400px]] <br />
<br />
<br />
<br />
<br />
<br />
<br />
Agora debuxa a liña do bordo de ataque como se mostra a continuación, desde a estación B, ata 16 mm (desde atrás) na estación C, e despois continúa ata a punta en 7 mm de atrás.<br />
<br />
[[File:04tur.jpeg|400px]]<br />
<br />
(Este debuxo non mostra o bit extra máis aló da punta que pode quedar na súa peza de traballo real). As medidas resúmense nesta táboa a continuación. As alturas son dende a parte traseira folla que despois descansará no banco. Elimina a madeira por encima desta altura. "Cheo" refírese ao grosor total da peza de madeira orixinal que está a usar.<br />
<br />
<br />
<br />
[[File:05tur.jpeg|400px]]<br />
<br />
'''O rastro''' A liña do bordo posterior comeza na parte inferior da liña diagonal na estación B e sobe a 5 mm en C, continuando a 5 mm ata a punta. Esta vista abaixo mostra a madeira xa eliminado entre as dúas liñas para formar a cara barlovento da pala.<br />
<br />
<br />
<br />
[[File:06tur.png|400px]]<br />
<br />
Esculpe esta cara de barlovento plana entre as dúas liñas. Coida que os bordos estean recto, seguindo as liñas. A mellor ferramenta para usar para rematar a parte exterior do a lámina é un plano, para dar un acabado suave e recto. Quizais necesites traballar no avión 45 graos coa peza de traballo, deslizando parcialmente cara aos lados, para formar a forma oca en estación C. Este paso complétase cando podes colocar unha regra pola cara entre os principais e liñas de bordo de saída e non hai "xoroba" no medio. Encha calquera chip ou pequeno ocos con recheo de madeira. Se hai algún erro grave, ou k grande non que se debilitan a folla, entón pode ter que ser descartada. Comprobe a "caída" usando un nivel como referencia. Suxeitar a madeira para que a parte da raíz sitúase nivelado e mida a diferenza de nivel entre os bordos de entrada e de saída. A diferenza ou "caída" debe ser de 11 mm no punto medio de 500 mm e de 2 mm no punta.<br />

''Pedagoxías do vento e das estrelas. As relacións sociais ás que (nunca estabamos destinados) a sobrevivir, tamén viven nos nosos corpos dolorosamente, e Audre Lorde non está aquí para lembrarnos esta lección, salvo na medida en que está presente no vento pedagóxico. Pero o vento é o noso mestre (74). -Alexis Pauline Gumbs'' do libro Mapping Queer Space(s) of Praxis and Pedagogy Editores: Elizabeth McNeil, James E. Wermers, Joshua O. Lunn'' <br />
<br />
<br />
Temos o pracer de comunicarvos que do 16 ao 29 de outubro Pin Biotranslab, Casa do Río e The Foundry establece unha colaboración para levar a cabo o evento Eco (i) Logic Queer Energy harvesting. O proxecto é posible grazas ao apoio de GOSH, unha rede para desenvolver e difundir proxectos baseados en hardware de código aberto para a ciencia. '''Eco (i) Logic Queer Recollida de enerxía''' O evento ten como obxectivo abordar a falta de mulleres, queer, trans e diversidade nos ámbitos tecnolóxicos en xeral e do hacking máis concretamente. Pero aínda máis, pretende crear unha comunidade que avalía criticamente as narrativas hexemónicas arredor das tecnoloxías, os aspectos de modernidade dos seus supostos occidentais subliñados e as súas inflexións capitalistas inherentes, entre outros. O obxectivo principal do evento é desenvolver kits que se centren na interacción co medio natural no ámbito da enerxía.. o obxectivo principal pasa pola captación de enerxía do medio natural, a través dos aeroxeradores. Estes kits de enerxía serán escalables e poderán utilizarse tanto como material pedagóxico como para instalar centrais eléctricas específicas do sitio en diferentes sitios tamén. Este traballo ten un compoñente contrainfraestrutural: unha posible consecuencia sería capacitar ás persoas para xerar a súa propia enerxía en lugar de depender de grandes empresas e moitas veces extractivas. <br />
<br />
== Introdución e valores do proceso == <br />
<br />
Aquí comeza a documentación do longo proceso de creación de prototipos do modelo Hugh Piggott The Piggott Turbine - Wind Empowerment dunha turbina eólica de código aberto. Estivemos cambiando un pouco os obxectivos do evento, pasando de desenvolver pequenos kits para ir a construír o aeroxerador de 2 m de tamaño real para proporcionar enerxía ás áreas rexionais rurais nas que estabamos traballando. Nese evento concreto estivemos traballando en The Foundry un bonito proxecto e asociación que instalamos no norte de GaliZA ao noroeste de España. Durante o evento activáronse moitas cousas entre os realizadores e os visitantes; En xeral foi unha experiencia marabillosa chea de cousas novas que estudar, aprender, facer e comprender xuntos. Escollemos este modelo porque estaba cheo de capas de interese nos niveis de aprendizaxe, comprensión e elaboración, aquí algúns niveis mesturados con capas: en primeiro lugar é un dos que é '''de código aberto''' ou polo menos ten a opción de acceder á documentación completa. realmente '''ricos a nivel pedagóxico''', realmente estivemos aprendendo a través da construción completa do propio xerador, sobre moitos temas como: <br />
<br />
* electromagnetismo *matemáticas * xeometría * electrónica * AC-DC *soldadura * talla en madeira * escultura e fundición de pezas e moito máis que foi alcanzando a través do agradable proceso de ler, aprender e construír xuntos.<br />
<br />
== Glosario == <br />
* '''AC-'''Corrente alterna producida polo alternador. Todos os fíos: palabra estadounidense para varilla ou tachuelas "roscadas" ou "hiladas".<br />

=== A fundición === <br />
<br />
A Fundición é unha organización sen ánimo de lucro con sede nunha aldea GaliZA anteriormente abandonada. Funciona tanto como residencia como como espazo de proxecto. Subscríbese aos ideais de autoorganización e ten os seguintes tres obxectivos: <br />
1. Organizar actividades no ámbito das artes, as ciencias e as humanidades fóra das institucións tradicionais, centradas no discurso crítico.<br />
2. Promover o intercambio de ideas e a colaboración intelectual fóra das limitacións impostas polo Estado e o mercado.<br />
3. Aumentar a autosuficiencia, a sustentabilidade e a concienciación co medio ambiente utilizando a tecnoloxía axeitada e o código aberto como principais recursos. Tendo en conta este contexto, o noso obxectivo é reforzar a capacidade de xerar redes que flúen do contexto rural ao urbano apoiando os intercambios non xerarquizados e democráticos de coñecementos e prácticas que permitan modelos novos e sostibles no contexto rural. Segundo iso consideramos que o novo creativo transdisciplinar dos sectores nos que estamos enredados poden ter un impacto enorme e positivo na creación deste novo paradigma.<br />
https://bravosfoundry.com/ <br />
Ademais, hai un foco temático na transdisciplinariedade, o transfeminismo e o poshumanismo. Aínda que este enfoque non é axeitadamente comprendido por categorías políticas identitarias como a raza ou o xénero, esperamos que leve á subversión das estruturas hexemónicas inscritas nos binarismos que sosteñen moitas destas categorías. O noso interese reside no desenvolvemento de ferramentas e tecnoloxías que subvertan as estruturas contemporáneas de dominación, explotación e marxinación, non nas que a reproducen. Buscamos desenvolver un entorno máis sostible abrindo as nosas prácticas baseadas nun marco de cultura libre, xerando redes e interese ao seu redor, posibilitando un fluxo de intercambio de innovación entre sectores creativos centrados na revalorización dos contextos rurais e do seu patrimonio de coñecemento. <br />

=== '''Sección 2, implica a construción de pezas do '''alternador''' utilizando os dispositivos da sección 1.''' === <br />
<br />
'''Alternador''' Cada rotor magnético é un disco de aceiro con 12 imáns colocados sobre el e colocados en resina. Os imáns son cada un de 50 x 50 x 20 mm, e só caben no disco. A idea é conseguir a máxima cantidade de fluxo nun espazo determinado. A turbina funciona a 650 rpm para unha saída de 400 W, polo que a forza centrífuga sobre os imáns é 60 veces a forza da gravidade. Para evitar que saian voando, hai que reforzar a fundición de resina. Un cable de aceiro inoxidable colócase arredor da parte exterior dos imáns para manter a fundición xunta a altas revolucións por minuto. Usamos inoxidable porque non é magnético, ou polo menos menos magnético que un cable de aceiro normal. Enrolarás as bobinas que producen a potencia de saída e fundirase en resina para formar un estator entre os dous rotores magnéticos. <br />

Paso - Xerador, rotor: Preparación do cubo da roda. <br />
[[File:frame10.jpg|200px]] '''O cubo da roda''' Podes atopar un cubo de roda traseira de coche usado (Golf, Toyota, etc.) que teña un xeito sinxelo engade o eixe ou, alternativamente, compre un cubos de remolque en liña novos a baixo custo. PCD ou "diámetro do círculo de paso" é o diámetro do círculo do patrón do burato no cubo, e normalmente este será de 100 mm para un cubo de roda de coche, ou de 4 polgadas para un cubo de remolque. Os hubs dos coches poden ter un tambor de freo que non precisa. Isto pódese eliminar usando a disco de corte nunha moedora. O enfoque máis sinxelo é facer catro cortes rectos ao redor os catro orificios na parte frontal, deixando unha superficie cadrada na que se monta o imán rotores. Estas fotos mostran un cubo de roda traseira de golf: primeiro se corta o tambor de freo e a continuación, o cubo acabado despois de cortar o tambor. Un típico cubo de coche de roda traseira con a brida no extremo traseiro do eixe do tronco que se pode reutilizar para montalo. Os cubos de remolque, por outra banda, son de calidade bastante básica, e os rodamentos tamén poden ser barato para uso a longo prazo, pero son artigos facilmente dispoñibles que se poden mercar en liña como novo. Os debuxos que aparecen a continuación (de autow.com) mostran un concentrador e un stub típicos eixe que se compran por separado. Debe estar preparado para substituír os rodamentos por unha marca nomeada (como SKF). É fácil de substituír os conos e rolos internos, pero hai que golpear as capas exteriores suavemente fóra do cubo cunha deriva adecuada. Mantéñaos rectos tocando uniformemente lados opostos e teña coidado de non raiar o asento. Paso - Xerador, rotor: <br />

=== Section 4, involves the craving of the blades and the welding of the base for the turbine generator. ===<br />
<br />
4.1 Making the blades <br />
The drawknife is useful for thicker chunks of wood, and for cutting down into a hollow. <br />
It can make a nice smooth job of the root of the blade, whereas the plane will work better <br />
where you need a very straight finish.<br />
<br />
'''Marking the stations.'''<br />
<br />
Place the blade with its best edge toward you on its upper surface. This will actually<br />
become the back or ‘downwind’ side of the finished blade.<br />
(Most of the front or windward side is to be cut off, so defects on this underneath side<br />
are not important.)<br />
<br />
The root of the blade will be on your right, the tip at the left, 1000 mm from the root<br />
(near the left end).<br />
<br />
Measure from the root, and mark four stations.<br />
Station A at 75mm<br />
Station B at 150 mm<br />
Station C at 500 mm<br />
The Tip at 1000 mm.<br />
<br />
<br />
At each station draw a line right around the workpiece using a square.<br />
<br />
[[File:01tur.jpeg|400px]]<br />
<br />
<br />
'''Tapering the blade'''<br />
The width of the blade tapers down from full size at station C to 55 mm wide at the<br />
tip. Mark the 55 mm tip width, measuring from the leading edge side. Draw a line<br />
though your mark to the trailing edge side at C station and cut off a triangular piece so<br />
as to achieve the correct tapered shape for the blade. Any knots in the triangular<br />
off cut do not matter as this piece is discarded. Try to make this a "square" cut,<br />
perpendicular to the back surface of the blade.<br />
You can do this with a circular saw, or by cross-cutting and shaving as described<br />
above.<br />
<br />
<br />
[[File:02tur.jpeg|400px]]<br />
<br />
'''Marking the leading and trailing edges'''<br />
The next step is to cut the windward face of the blade. This face is defined by the<br />
leading and trailing edge lines of the blade. These lines need to be marked with<br />
reference to the back face of the wood which has been uppermost in the previous<br />
operation.<br />
<br />
Turn the wood over. Start by drawing two diagonal lines between stations A and B<br />
on the front or windward side (see below). One is on the front face and the other on<br />
the trailing edge which is now toward you. <br />
<br />
[[File:03tur.jpeg|400px]]<br />
<br />
<br />
Now draw the leading edge line as shown below, <br />
from station B, down to 16mm(from the back) at station C, then continuing to the tip at<br />
7mm from the back.<br />
<br />
[[File:04tur.jpeg|400px]]<br />
<br />
<br />
(This drawing does not show the extra bit beyond the tip which may remain <br />
in your actual workpiece.)<br />
<br />
Measurements are summarised in this table below. Heights are from the back of the<br />
blade which will then rest on the bench. Remove the wood above this height. "Full"<br />
refers to the full thickness of the original piece of wood you are using.<br />
<br />
<br />
<br />
[[File:05tur.jpeg|400px]]<br />
<br />
<br />
'''The trailing''' <br />
The trailing edge line starts at the bottom of the diagonal line at station B, and <br />
rises to 5mm at C, continuing at 5 mm to the tip. This view below shows the wood <br />
already removed between the two lines to form the windward face of the blade.<br />
<br />
<br />
[[File:06tur.png|400px]]<br />
<br />
<br />
Carve this flat windward face between the 2 lines. Take care that the edges are<br />
straight, following the lines. The best tool to use for finishing the outer part of the<br />
blade is a plane, to give a smooth, straight finish. You may need to work the plane at<br />
45 degrees to the workpiece, sliding partly sideways, to form the hollow shape at<br />
station C.<br />
<br />
This step is completed when you can place a ruler across the face between the leading<br />
and trailing edge lines and there is no ‘hump’ in the middle. Fill any chips or small<br />
hollows with wood filler. If there are any serious errors, or large knots that weaken<br />
the blade then it may have to be discarded.<br />
Check the “drop” using a level as a reference. Clamp the wood so that the root part<br />
sits level, and measure the difference in level between the leading and trailing edges.<br />
The difference or “drop” should be 11 mm at the 500 mm mid-point, and 2 mm at the<br />
tip.<br />

''Pedagoxías do vento e das estrelas. As relacións sociais ás que (nunca estabamos destinados) a sobrevivir, tamén viven nos nosos corpos dolorosamente, e Audre Lorde non está aquí para lembrarnos esta lección, salvo na medida en que está presente no vento pedagóxico. Pero o vento é o noso mestre (74). -Alexis Pauline Gumbs'' do libro Mapping Queer Space(s) of Praxis and Pedagogy Editores: Elizabeth McNeil, James E. Wermers, Joshua O. Lunn'' <br />
<br />
<br />
Temos o pracer de comunicarvos que do 16 ao 29 de outubro Pin Biotranslab, Casa do Río e The Foundry establece unha colaboración para levar a cabo o evento Eco (i) Logic Queer Energy harvesting. O proxecto é posible grazas ao apoio de GOSH, unha rede para desenvolver e difundir proxectos baseados en hardware de código aberto para a ciencia. '''Eco (i) Logic Queer Recollida de enerxía''' O evento ten como obxectivo abordar a falta de mulleres, queer, trans e diversidade nos ámbitos tecnolóxicos en xeral e do hacking máis concretamente. Pero aínda máis, pretende crear unha comunidade que avalía criticamente as narrativas hexemónicas arredor das tecnoloxías, os aspectos de modernidade dos seus supostos occidentais subliñados e as súas inflexións capitalistas inherentes, entre outros. O obxectivo principal do evento é desenvolver kits que se centren na interacción co medio natural no ámbito da enerxía.. o obxectivo principal pasa pola captación de enerxía do medio natural, a través dos aeroxeradores. Estes kits de enerxía serán escalables e poderán utilizarse tanto como material pedagóxico como para instalar centrais eléctricas específicas do sitio en diferentes sitios tamén. Este traballo ten un compoñente contrainfraestrutural: unha posible consecuencia sería capacitar ás persoas para xerar a súa propia enerxía en lugar de depender de grandes empresas e moitas veces extractivas. <br />
<br />
== Introdución e valores do proceso == <br />
<br />
Aquí comeza a documentación do longo proceso de creación de prototipos do modelo Hugh Piggott The Piggott Turbine - Wind Empowerment dunha turbina eólica de código aberto. Estivemos cambiando un pouco os obxectivos do evento, pasando de desenvolver pequenos kits para ir a construír o aeroxerador de 2 m de tamaño real para proporcionar enerxía ás áreas rexionais rurais nas que estabamos traballando. Nese evento concreto estivemos traballando en The Foundry un bonito proxecto e asociación que instalamos no norte de GaliZA ao noroeste de España. Durante o evento activáronse moitas cousas entre os realizadores e os visitantes; En xeral foi unha experiencia marabillosa chea de cousas novas que estudar, aprender, facer e comprender xuntos. Escollemos este modelo porque estaba cheo de capas de interese nos niveis de aprendizaxe, comprensión e elaboración, aquí algúns niveis mesturados con capas: en primeiro lugar é un dos que é '''de código aberto''' ou polo menos ten a opción de acceder á documentación completa. realmente '''ricos a nivel pedagóxico''', realmente estivemos aprendendo a través da construción completa do propio xerador, sobre moitos temas como: <br />
<br />
* electromagnetismo *matemáticas * xeometría * electrónica * AC-DC *soldadura * talla en madeira * escultura e fundición de pezas e moito máis que foi alcanzando a través do agradable proceso de ler, aprender e construír xuntos.<br />
<br />
== Glosario == <br />
* '''AC-'''Corrente alterna producida polo alternador. Todos os fíos: palabra estadounidense para varilla ou tachuelas "roscadas" ou "hiladas".<br />
* '''Interruptor de freo''' - Interruptor usado para curtocircuitar os cables do alternador para que se pare.<br />
* '''Catalizador''' - Un produto químico usado para facer sólido o conxunto de resinas de poliéster. O catalizador reacciona co "acelerador" xa presente na mestura de resina. A calor de reacción establece o poliéster.<br />
* '''Cavalier''' - Unha marca de coche. O cavalier no Reino Unido non é o mesmo que o Cavalier nos EUA, pero ambos teñen cubos de roda útiles.<br />
* '''DC - corrente continua''' cun lado positivo e outro negativo, como nos circuítos de batería.<br />
* '''Diámetro''' - A distancia dun lado a outro dun círculo. O ancho dun disco no medio.<br />
* '''Fase''' - O tempo da alternancia cíclica da tensión nun circuíto. As diferentes fases alcanzarán o pico en diferentes momentos.<br />
* '''Poliéster''' - Un tipo de resina utilizada no traballo de fibra de vidro. Tamén apto para facer fundicións.<br />
* '''Potencia''' - a taxa de entrega de enerxía<br />

=== A fundición === <br />
<br />
A Fundición é unha organización sen ánimo de lucro con sede nunha aldea GaliZA anteriormente abandonada. Funciona tanto como residencia como como espazo de proxecto. Subscríbese aos ideais de autoorganización e ten os seguintes tres obxectivos: <br />
1. Organizar actividades no ámbito das artes, as ciencias e as humanidades fóra das institucións tradicionais, centradas no discurso crítico.<br />
2. Promover o intercambio de ideas e a colaboración intelectual fóra das limitacións impostas polo Estado e o mercado.<br />
3. Aumentar a autosuficiencia, a sustentabilidade e a concienciación co medio ambiente utilizando a tecnoloxía axeitada e o código aberto como principais recursos. Tendo en conta este contexto, o noso obxectivo é reforzar a capacidade de xerar redes que flúen do contexto rural ao urbano apoiando os intercambios non xerarquizados e democráticos de coñecementos e prácticas que permitan modelos novos e sostibles no contexto rural. Segundo iso consideramos que o novo creativo transdisciplinar dos sectores nos que estamos enredados poden ter un impacto enorme e positivo na creación deste novo paradigma.<br />
https://bravosfoundry.com/ <br />
Ademais, hai un foco temático na transdisciplinariedade, o transfeminismo e o poshumanismo. Aínda que este enfoque non é axeitadamente comprendido por categorías políticas identitarias como a raza ou o xénero, esperamos que leve á subversión das estruturas hexemónicas inscritas nos binarismos que sosteñen moitas destas categorías. O noso interese reside no desenvolvemento de ferramentas e tecnoloxías que subvertan as estruturas contemporáneas de dominación, explotación e marxinación, non nas que a reproducen. Buscamos desenvolver un entorno máis sostible abrindo as nosas prácticas baseadas nun marco de cultura libre, xerando redes e interese ao seu redor, posibilitando un fluxo de intercambio de innovación entre sectores creativos centrados na revalorización dos contextos rurais e do seu patrimonio de coñecemento. <br />

=== '''Sección 2, implica a construción de pezas do '''alternador''' utilizando os dispositivos da sección 1.''' === <br />
<br />
'''Alternador''' Cada rotor magnético é un disco de aceiro con 12 imáns colocados sobre el e colocados en resina. Os imáns son cada un de 50 x 50 x 20 mm, e só caben no disco. A idea é conseguir a máxima cantidade de fluxo nun espazo determinado. A turbina funciona a 650 rpm para unha saída de 400 W, polo que a forza centrífuga sobre os imáns é 60 veces a forza da gravidade. Para evitar que saian voando, hai que reforzar a fundición de resina. Un cable de aceiro inoxidable colócase arredor da parte exterior dos imáns para manter a fundición xunta a altas revolucións por minuto. Usamos inoxidable porque non é magnético, ou polo menos menos magnético que un cable de aceiro normal. Enrolarás as bobinas que producen a potencia de saída e fundirase en resina para formar un estator entre os dous rotores magnéticos. <br />

Paso - Xerador, rotor: Preparación do cubo da roda. <br />
[[File:frame10.jpg|200px]] '''O cubo da roda''' Podes atopar un cubo de roda traseira de coche usado (Golf, Toyota, etc.) que teña un xeito sinxelo engade o eixe ou, alternativamente, compre un cubos de remolque en liña novos a baixo custo. PCD ou "diámetro do círculo de paso" é o diámetro do círculo do patrón do burato no cubo, e normalmente este será de 100 mm para un cubo de roda de coche, ou de 4 polgadas para un cubo de remolque. Os hubs dos coches poden ter un tambor de freo que non precisa. Isto pódese eliminar usando a disco de corte nunha moedora. O enfoque máis sinxelo é facer catro cortes rectos ao redor os catro orificios na parte frontal, deixando unha superficie cadrada na que se monta o imán rotores. Estas fotos mostran un cubo de roda traseira de golf: primeiro se corta o tambor de freo e a continuación, o cubo acabado despois de cortar o tambor. Un típico cubo de coche de roda traseira con a brida no extremo traseiro do eixe do tronco que se pode reutilizar para montalo. Os cubos de remolque, por outra banda, son de calidade bastante básica, e os rodamentos tamén poden ser barato para uso a longo prazo, pero son artigos facilmente dispoñibles que se poden mercar en liña como novo. Os debuxos que aparecen a continuación (de autow.com) mostran un concentrador e un stub típicos eixe que se compran por separado. Debe estar preparado para substituír os rodamentos por unha marca nomeada (como SKF). É fácil de substituír os conos e rolos internos, pero hai que golpear as capas exteriores suavemente fóra do cubo cunha deriva adecuada. Mantéñaos rectos tocando uniformemente lados opostos e teña coidado de non raiar o asento. Paso - Xerador, rotor: <br />

=== Section 4, involves the craving of the blades and the welding of the base for the turbine generator. ===<br />
<br />
4.1 Making the blades <br />
The drawknife is useful for thicker chunks of wood, and for cutting down into a hollow. <br />
It can make a nice smooth job of the root of the blade, whereas the plane will work better <br />
where you need a very straight finish.<br />
<br />
'''Marking the stations.'''<br />
<br />
Place the blade with its best edge toward you on its upper surface. This will actually<br />
become the back or ‘downwind’ side of the finished blade.<br />
(Most of the front or windward side is to be cut off, so defects on this underneath side<br />
are not important.)<br />
<br />
The root of the blade will be on your right, the tip at the left, 1000 mm from the root<br />
(near the left end).<br />
<br />
Measure from the root, and mark four stations.<br />
Station A at 75mm<br />
Station B at 150 mm<br />
Station C at 500 mm<br />
The Tip at 1000 mm.<br />
<br />
<br />
At each station draw a line right around the workpiece using a square.<br />
<br />
[[File:01tur.jpeg|400px]]<br />
<br />
<br />
'''Tapering the blade'''<br />
The width of the blade tapers down from full size at station C to 55 mm wide at the<br />
tip. Mark the 55 mm tip width, measuring from the leading edge side. Draw a line<br />
though your mark to the trailing edge side at C station and cut off a triangular piece so<br />
as to achieve the correct tapered shape for the blade. Any knots in the triangular<br />
off cut do not matter as this piece is discarded. Try to make this a "square" cut,<br />
perpendicular to the back surface of the blade.<br />
You can do this with a circular saw, or by cross-cutting and shaving as described<br />
above.<br />
<br />
<br />
[[File:02tur.jpeg|400px]]<br />
<br />
'''Marking the leading and trailing edges'''<br />
The next step is to cut the windward face of the blade. This face is defined by the<br />
leading and trailing edge lines of the blade. These lines need to be marked with<br />
reference to the back face of the wood which has been uppermost in the previous<br />
operation.<br />
<br />
Turn the wood over. Start by drawing two diagonal lines between stations A and B<br />
on the front or windward side (see below). One is on the front face and the other on<br />
the trailing edge which is now toward you. <br />
<br />
[[File:03tur.jpeg|400px]]<br />
<br />
<br />
Now draw the leading edge line as shown below, <br />
from station B, down to 16mm(from the back) at station C, then continuing to the tip at<br />
7mm from the back.<br />
<br />
[[File:04tur.jpeg|400px]]<br />
<br />
<br />
(This drawing does not show the extra bit beyond the tip which may remain <br />
in your actual workpiece.)<br />
<br />
Measurements are summarised in this table below. Heights are from the back of the<br />
blade which will then rest on the bench. Remove the wood above this height. "Full"<br />
refers to the full thickness of the original piece of wood you are using.<br />
<br />
<br />
<br />
[[File:05tur.jpeg|400px]]<br />
<br />
<br />
'''The trailing''' <br />
The trailing edge line starts at the bottom of the diagonal line at station B, and <br />
rises to 5mm at C, continuing at 5 mm to the tip. This view below shows the wood <br />
already removed between the two lines to form the windward face of the blade.<br />
<br />
<br />
[[File:06tur.png|400px]]<br />
<br />
<br />
Carve this flat windward face between the 2 lines. Take care that the edges are<br />
straight, following the lines. The best tool to use for finishing the outer part of the<br />
blade is a plane, to give a smooth, straight finish. You may need to work the plane at<br />
45 degrees to the workpiece, sliding partly sideways, to form the hollow shape at<br />
station C.<br />
<br />
This step is completed when you can place a ruler across the face between the leading<br />
and trailing edge lines and there is no ‘hump’ in the middle. Fill any chips or small<br />
hollows with wood filler. If there are any serious errors, or large knots that weaken<br />
the blade then it may have to be discarded.<br />
Check the “drop” using a level as a reference. Clamp the wood so that the root part<br />
sits level, and measure the difference in level between the leading and trailing edges.<br />
The difference or “drop” should be 11 mm at the 500 mm mid-point, and 2 mm at the<br />
tip.<br />

''Pedagoxías do vento e das estrelas. As relacións sociais ás que (nunca estabamos destinados) a sobrevivir, tamén viven nos nosos corpos dolorosamente, e Audre Lorde non está aquí para lembrarnos esta lección, salvo na medida en que está presente no vento pedagóxico. Pero o vento é o noso mestre (74). -Alexis Pauline Gumbs'' do libro Mapping Queer Space(s) of Praxis and Pedagogy Editores: Elizabeth McNeil, James E. Wermers, Joshua O. Lunn'' <br />
<br />
<br />
Temos o pracer de comunicarvos que do 16 ao 29 de outubro Pin Biotranslab, Casa do Río e The Foundry establece unha colaboración para levar a cabo o evento Eco (i) Logic Queer Energy harvesting. O proxecto é posible grazas ao apoio de GOSH, unha rede para desenvolver e difundir proxectos baseados en hardware de código aberto para a ciencia. '''Eco (i) Logic Queer Recollida de enerxía''' O evento ten como obxectivo abordar a falta de mulleres, queer, trans e diversidade nos ámbitos tecnolóxicos en xeral e do hacking máis concretamente. Pero aínda máis, pretende crear unha comunidade que avalía criticamente as narrativas hexemónicas arredor das tecnoloxías, os aspectos de modernidade dos seus supostos occidentais subliñados e as súas inflexións capitalistas inherentes, entre outros. O obxectivo principal do evento é desenvolver kits que se centren na interacción co medio natural no ámbito da enerxía.. o obxectivo principal pasa pola captación de enerxía do medio natural, a través dos aeroxeradores. Estes kits de enerxía serán escalables e poderán utilizarse tanto como material pedagóxico como para instalar centrais eléctricas específicas do sitio en diferentes sitios tamén. Este traballo ten un compoñente contrainfraestrutural: unha posible consecuencia sería capacitar ás persoas para xerar a súa propia enerxía en lugar de depender de grandes empresas e moitas veces extractivas. <br />
<br />
== Introdución e valores do proceso == <br />
<br />
Aquí comeza a documentación do longo proceso de creación de prototipos do modelo Hugh Piggott The Piggott Turbine - Wind Empowerment dunha turbina eólica de código aberto. Estivemos cambiando un pouco os obxectivos do evento, pasando de desenvolver pequenos kits para ir a construír o aeroxerador de 2 m de tamaño real para proporcionar enerxía ás áreas rexionais rurais nas que estabamos traballando. Nese evento concreto estivemos traballando en The Foundry un bonito proxecto e asociación que instalamos no norte de GaliZA ao noroeste de España. Durante o evento activáronse moitas cousas entre os realizadores e os visitantes; En xeral foi unha experiencia marabillosa chea de cousas novas que estudar, aprender, facer e comprender xuntos. Escollemos este modelo porque estaba cheo de capas de interese nos niveis de aprendizaxe, comprensión e elaboración, aquí algúns niveis mesturados con capas: en primeiro lugar é un dos que é '''de código aberto''' ou polo menos ten a opción de acceder á documentación completa. realmente '''ricos a nivel pedagóxico''', realmente estivemos aprendendo a través da construción completa do propio xerador, sobre moitos temas como: <br />
<br />
* electromagnetismo *matemáticas * xeometría * electrónica * AC-DC *soldadura * talla en madeira * escultura e fundición de pezas e moito máis que foi alcanzando a través do agradable proceso de ler, aprender e construír xuntos.<br />
<br />
== Glosario == <br />
* '''AC-'''Corrente alterna producida polo alternador. Todos os fíos: palabra estadounidense para varilla ou tachuelas "roscadas" ou "hiladas".<br />
* '''Interruptor de freo''' - Interruptor usado para curtocircuitar os cables do alternador para que se pare.<br />
* '''Catalizador''' - Un produto químico usado para facer sólido o conxunto de resinas de poliéster. O catalizador reacciona co "acelerador" xa presente na mestura de resina. A calor de reacción establece o poliéster.<br />
* '''Cavalier''' - Unha marca de coche. O cavalier no Reino Unido non é o mesmo que o Cavalier nos EUA, pero ambos teñen cubos de roda útiles.<br />
* '''DC - corrente continua''' cun lado positivo e outro negativo, como nos circuítos de batería.<br />
* '''Diámetro''' - A distancia dun lado a outro dun círculo. O ancho dun disco no medio.<br />
* '''Fase''' - O tempo da alternancia cíclica da tensión nun circuíto. As diferentes fases alcanzarán o pico en diferentes momentos.<br />
* '''Poliéster''' - Un tipo de resina utilizada no traballo de fibra de vidro. Tamén apto para facer fundicións.<br />
* '''Potencia''' - a taxa de entrega de enerxía<br />
* '''Rectifier''' - Un dispositivo semicondutor que converte AC en DC para cargar a batería.<br />
* '''Raíz''' - A parte máis ancha da lámina preto do cubo no centro do rotor.<br />
* '''Rotor''' - Unha parte xiratoria. Os rotores de imáns son os discos de aceiro que transportan os imáns máis alá do estator. As palas do rotor son a "hélice" impulsado polo vento e impulsando os rotores magnéticos.<br />
* '''Soldadura''': un método para facer conexións eléctricas entre fíos usando un 'ferro' quente e recubrindo todo con soldadura fundida.<br />
* '''Arrastre''' - Forza que exerce o vento sobre un obxecto. O arrastre é paralelo á dirección do vento no obxecto. (ver Ascensor)<br />
* '''Estator''' - Un conxunto de bobinas incrustadas nunha lousa de resina para formar parte do alternador.

=== A fundición === <br />
<br />
A Fundición é unha organización sen ánimo de lucro con sede nunha aldea GaliZA anteriormente abandonada. Funciona tanto como residencia como como espazo de proxecto. Subscríbese aos ideais de autoorganización e ten os seguintes tres obxectivos: <br />
1. Organizar actividades no ámbito das artes, as ciencias e as humanidades fóra das institucións tradicionais, centradas no discurso crítico.<br />
2. Promover o intercambio de ideas e a colaboración intelectual fóra das limitacións impostas polo Estado e o mercado.<br />
3. Aumentar a autosuficiencia, a sustentabilidade e a concienciación co medio ambiente utilizando a tecnoloxía axeitada e o código aberto como principais recursos. Tendo en conta este contexto, o noso obxectivo é reforzar a capacidade de xerar redes que flúen do contexto rural ao urbano apoiando os intercambios non xerarquizados e democráticos de coñecementos e prácticas que permitan modelos novos e sostibles no contexto rural. Segundo iso consideramos que o novo creativo transdisciplinar dos sectores nos que estamos enredados poden ter un impacto enorme e positivo na creación deste novo paradigma.<br />
https://bravosfoundry.com/ <br />
Ademais, hai un foco temático na transdisciplinariedade, o transfeminismo e o poshumanismo. Aínda que este enfoque non é axeitadamente comprendido por categorías políticas identitarias como a raza ou o xénero, esperamos que leve á subversión das estruturas hexemónicas inscritas nos binarismos que sosteñen moitas destas categorías. O noso interese reside no desenvolvemento de ferramentas e tecnoloxías que subvertan as estruturas contemporáneas de dominación, explotación e marxinación, non nas que a reproducen. Buscamos desenvolver un entorno máis sostible abrindo as nosas prácticas baseadas nun marco de cultura libre, xerando redes e interese ao seu redor, posibilitando un fluxo de intercambio de innovación entre sectores creativos centrados na revalorización dos contextos rurais e do seu patrimonio de coñecemento. <br />

=== '''Sección 2, implica a construción de pezas do '''alternador''' utilizando os dispositivos da sección 1.''' === <br />
<br />
'''Alternador''' Cada rotor magnético é un disco de aceiro con 12 imáns colocados sobre el e colocados en resina. Os imáns son cada un de 50 x 50 x 20 mm, e só caben no disco. A idea é conseguir a máxima cantidade de fluxo nun espazo determinado. A turbina funciona a 650 rpm para unha saída de 400 W, polo que a forza centrífuga sobre os imáns é 60 veces a forza da gravidade. Para evitar que saian voando, hai que reforzar a fundición de resina. Un cable de aceiro inoxidable colócase arredor da parte exterior dos imáns para manter a fundición xunta a altas revolucións por minuto. Usamos inoxidable porque non é magnético, ou polo menos menos magnético que un cable de aceiro normal. Enrolarás as bobinas que producen a potencia de saída e fundirase en resina para formar un estator entre os dous rotores magnéticos. <br />

Paso - Xerador, rotor: Preparación do cubo da roda. <br />
[[File:frame10.jpg|200px]] '''O cubo da roda''' Podes atopar un cubo de roda traseira de coche usado (Golf, Toyota, etc.) que teña un xeito sinxelo engade o eixe ou, alternativamente, compre un cubos de remolque en liña novos a baixo custo. PCD ou "diámetro do círculo de paso" é o diámetro do círculo do patrón do burato no cubo, e normalmente este será de 100 mm para un cubo de roda de coche, ou de 4 polgadas para un cubo de remolque. Os hubs dos coches poden ter un tambor de freo que non precisa. Isto pódese eliminar usando a disco de corte nunha moedora. O enfoque máis sinxelo é facer catro cortes rectos ao redor os catro orificios na parte frontal, deixando unha superficie cadrada na que se monta o imán rotores. Estas fotos mostran un cubo de roda traseira de golf: primeiro se corta o tambor de freo e a continuación, o cubo acabado despois de cortar o tambor. Un típico cubo de coche de roda traseira con a brida no extremo traseiro do eixe do tronco que se pode reutilizar para montalo. Os cubos de remolque, por outra banda, son de calidade bastante básica, e os rodamentos tamén poden ser barato para uso a longo prazo, pero son artigos facilmente dispoñibles que se poden mercar en liña como novo. Os debuxos que aparecen a continuación (de autow.com) mostran un concentrador e un stub típicos eixe que se compran por separado. Debe estar preparado para substituír os rodamentos por unha marca nomeada (como SKF). É fácil de substituír os conos e rolos internos, pero hai que golpear as capas exteriores suavemente fóra do cubo cunha deriva adecuada. Mantéñaos rectos tocando uniformemente lados opostos e teña coidado de non raiar o asento. Paso - Xerador, rotor: <br />

=== Section 4, involves the craving of the blades and the welding of the base for the turbine generator. ===<br />
<br />
4.1 Making the blades <br />
The drawknife is useful for thicker chunks of wood, and for cutting down into a hollow. <br />
It can make a nice smooth job of the root of the blade, whereas the plane will work better <br />
where you need a very straight finish.<br />
<br />
'''Marking the stations.'''<br />
<br />
Place the blade with its best edge toward you on its upper surface. This will actually<br />
become the back or ‘downwind’ side of the finished blade.<br />
(Most of the front or windward side is to be cut off, so defects on this underneath side<br />
are not important.)<br />
<br />
The root of the blade will be on your right, the tip at the left, 1000 mm from the root<br />
(near the left end).<br />
<br />
Measure from the root, and mark four stations.<br />
Station A at 75mm<br />
Station B at 150 mm<br />
Station C at 500 mm<br />
The Tip at 1000 mm.<br />
<br />
<br />
At each station draw a line right around the workpiece using a square.<br />
<br />
[[File:01tur.jpeg|400px]]<br />
<br />
<br />
'''Tapering the blade'''<br />
The width of the blade tapers down from full size at station C to 55 mm wide at the<br />
tip. Mark the 55 mm tip width, measuring from the leading edge side. Draw a line<br />
though your mark to the trailing edge side at C station and cut off a triangular piece so<br />
as to achieve the correct tapered shape for the blade. Any knots in the triangular<br />
off cut do not matter as this piece is discarded. Try to make this a "square" cut,<br />
perpendicular to the back surface of the blade.<br />
You can do this with a circular saw, or by cross-cutting and shaving as described<br />
above.<br />
<br />
<br />
[[File:02tur.jpeg|400px]]<br />
<br />
'''Marking the leading and trailing edges'''<br />
The next step is to cut the windward face of the blade. This face is defined by the<br />
leading and trailing edge lines of the blade. These lines need to be marked with<br />
reference to the back face of the wood which has been uppermost in the previous<br />
operation.<br />
<br />
Turn the wood over. Start by drawing two diagonal lines between stations A and B<br />
on the front or windward side (see below). One is on the front face and the other on<br />
the trailing edge which is now toward you. <br />
<br />
[[File:03tur.jpeg|400px]]<br />
<br />
<br />
Now draw the leading edge line as shown below, <br />
from station B, down to 16mm(from the back) at station C, then continuing to the tip at<br />
7mm from the back.<br />
<br />
[[File:04tur.jpeg|400px]]<br />
<br />
<br />
(This drawing does not show the extra bit beyond the tip which may remain <br />
in your actual workpiece.)<br />
<br />
Measurements are summarised in this table below. Heights are from the back of the<br />
blade which will then rest on the bench. Remove the wood above this height. "Full"<br />
refers to the full thickness of the original piece of wood you are using.<br />
<br />
<br />
<br />
[[File:05tur.jpeg|400px]]<br />
<br />
<br />
'''The trailing''' <br />
The trailing edge line starts at the bottom of the diagonal line at station B, and <br />
rises to 5mm at C, continuing at 5 mm to the tip. This view below shows the wood <br />
already removed between the two lines to form the windward face of the blade.<br />
<br />
<br />
[[File:06tur.png|400px]]<br />
<br />
<br />
Carve this flat windward face between the 2 lines. Take care that the edges are<br />
straight, following the lines. The best tool to use for finishing the outer part of the<br />
blade is a plane, to give a smooth, straight finish. You may need to work the plane at<br />
45 degrees to the workpiece, sliding partly sideways, to form the hollow shape at<br />
station C.<br />
<br />
This step is completed when you can place a ruler across the face between the leading<br />
and trailing edge lines and there is no ‘hump’ in the middle. Fill any chips or small<br />
hollows with wood filler. If there are any serious errors, or large knots that weaken<br />
the blade then it may have to be discarded.<br />
Check the “drop” using a level as a reference. Clamp the wood so that the root part<br />
sits level, and measure the difference in level between the leading and trailing edges.<br />
The difference or “drop” should be 11 mm at the 500 mm mid-point, and 2 mm at the<br />
tip.<br />

''Pedagoxías do vento e das estrelas. As relacións sociais ás que (nunca estabamos destinados) a sobrevivir, tamén viven nos nosos corpos dolorosamente, e Audre Lorde non está aquí para lembrarnos esta lección, salvo na medida en que está presente no vento pedagóxico. Pero o vento é o noso mestre (74). -Alexis Pauline Gumbs'' do libro Mapping Queer Space(s) of Praxis and Pedagogy Editores: Elizabeth McNeil, James E. Wermers, Joshua O. Lunn'' <br />
<br />
<br />
Temos o pracer de comunicarvos que do 16 ao 29 de outubro Pin Biotranslab, Casa do Río e The Foundry establece unha colaboración para levar a cabo o evento Eco (i) Logic Queer Energy harvesting. O proxecto é posible grazas ao apoio de GOSH, unha rede para desenvolver e difundir proxectos baseados en hardware de código aberto para a ciencia. '''Eco (i) Logic Queer Recollida de enerxía''' O evento ten como obxectivo abordar a falta de mulleres, queer, trans e diversidade nos ámbitos tecnolóxicos en xeral e do hacking máis concretamente. Pero aínda máis, pretende crear unha comunidade que avalía criticamente as narrativas hexemónicas arredor das tecnoloxías, os aspectos de modernidade dos seus supostos occidentais subliñados e as súas inflexións capitalistas inherentes, entre outros. O obxectivo principal do evento é desenvolver kits que se centren na interacción co medio natural no ámbito da enerxía.. o obxectivo principal pasa pola captación de enerxía do medio natural, a través dos aeroxeradores. Estes kits de enerxía serán escalables e poderán utilizarse tanto como material pedagóxico como para instalar centrais eléctricas específicas do sitio en diferentes sitios tamén. Este traballo ten un compoñente contrainfraestrutural: unha posible consecuencia sería capacitar ás persoas para xerar a súa propia enerxía en lugar de depender de grandes empresas e moitas veces extractivas. <br />
<br />
== Introdución e valores do proceso == <br />
<br />
Aquí comeza a documentación do longo proceso de creación de prototipos do modelo Hugh Piggott The Piggott Turbine - Wind Empowerment dunha turbina eólica de código aberto. Estivemos cambiando un pouco os obxectivos do evento, pasando de desenvolver pequenos kits para ir a construír o aeroxerador de 2 m de tamaño real para proporcionar enerxía ás áreas rexionais rurais nas que estabamos traballando. Nese evento concreto estivemos traballando en The Foundry un bonito proxecto e asociación que instalamos no norte de GaliZA ao noroeste de España. Durante o evento activáronse moitas cousas entre os realizadores e os visitantes; En xeral foi unha experiencia marabillosa chea de cousas novas que estudar, aprender, facer e comprender xuntos. Escollemos este modelo porque estaba cheo de capas de interese nos niveis de aprendizaxe, comprensión e elaboración, aquí algúns niveis mesturados con capas: en primeiro lugar é un dos que é '''de código aberto''' ou polo menos ten a opción de acceder á documentación completa. realmente '''ricos a nivel pedagóxico''', realmente estivemos aprendendo a través da construción completa do propio xerador, sobre moitos temas como: <br />
<br />
* electromagnetismo *matemáticas * xeometría * electrónica * AC-DC *soldadura * talla en madeira * escultura e fundición de pezas e moito máis que foi alcanzando a través do agradable proceso de ler, aprender e construír xuntos.<br />
<br />
== Glosario == <br />
* '''AC-'''Corrente alterna producida polo alternador. Todos os fíos: palabra estadounidense para varilla ou tachuelas "roscadas" ou "hiladas".<br />
* '''Interruptor de freo''' - Interruptor usado para curtocircuitar os cables do alternador para que se pare.<br />
* '''Catalizador''' - Un produto químico usado para facer sólido o conxunto de resinas de poliéster. O catalizador reacciona co "acelerador" xa presente na mestura de resina. A calor de reacción establece o poliéster.<br />
* '''Cavalier''' - Unha marca de coche. O cavalier no Reino Unido non é o mesmo que o Cavalier nos EUA, pero ambos teñen cubos de roda útiles.<br />
* '''DC - corrente continua''' cun lado positivo e outro negativo, como nos circuítos de batería.<br />
* '''Diámetro''' - A distancia dun lado a outro dun círculo. O ancho dun disco no medio.<br />
* '''Fase''' - O tempo da alternancia cíclica da tensión nun circuíto. As diferentes fases alcanzarán o pico en diferentes momentos.<br />
* '''Poliéster''' - Un tipo de resina utilizada no traballo de fibra de vidro. Tamén apto para facer fundicións.<br />
* '''Potencia''' - a taxa de entrega de enerxía<br />
* '''Rectifier''' - Un dispositivo semicondutor que converte AC en DC para cargar a batería.<br />
* '''Raíz''' - A parte máis ancha da lámina preto do cubo no centro do rotor.<br />
* '''Rotor''' - Unha parte xiratoria. Os rotores de imáns son os discos de aceiro que transportan os imáns máis alá do estator. As palas do rotor son a "hélice" impulsado polo vento e impulsando os rotores magnéticos.<br />
* '''Soldadura''': un método para facer conexións eléctricas entre fíos usando un 'ferro' quente e recubrindo todo con soldadura fundida.<br />
* '''Arrastre''' - Forza que exerce o vento sobre un obxecto. O arrastre é paralelo á dirección do vento no obxecto. (ver Ascensor)<br />
* '''Estator''' - Un conxunto de bobinas incrustadas nunha lousa de resina para formar parte do alternador. Os imáns inducen unha tensión nas bobinas e podemos utilizala para cargar unha batería. * '''Gota''': úsase aquí para describir unha determinada medida da forma da lámina dun muíño de vento. A "caída" afecta o ángulo de a lámina ao vento. Monómero de estireno - Un disolvente con cheiro desagradable na mestura de resina de poliéster.<br />
* '''Flux''' - As 'cousas' do magnetismo. Semellante á "corrente" na electricidade. Pódese visualizar como "liñas" que saen dun polo e volvendo ao outro.<br />
* '''Furling''' - Unha acción protectora que reduce a exposición a ventos violentos ao enfrontar as aspas lonxe delas.<br />
* '''Jig''' - Un dispositivo usado para manter os imáns no seu lugar antes de colocalos na resina.<br />

. == O espazo == <br />
<br />
=== A fundición === <br />
<br />
A Fundición é unha organización sen ánimo de lucro con sede nunha aldea GaliZA anteriormente abandonada. Funciona tanto como residencia como como espazo de proxecto. Subscríbese aos ideais de autoorganización e ten os seguintes tres obxectivos: <br />
1. Organizar actividades no ámbito das artes, as ciencias e as humanidades fóra das institucións tradicionais, centradas no discurso crítico.<br />
2. Promover o intercambio de ideas e a colaboración intelectual fóra das limitacións impostas polo Estado e o mercado.<br />
3. Aumentar a autosuficiencia, a sustentabilidade e a concienciación co medio ambiente utilizando a tecnoloxía axeitada e o código aberto como principais recursos. Tendo en conta este contexto, o noso obxectivo é reforzar a capacidade de xerar redes que flúen do contexto rural ao urbano apoiando os intercambios non xerarquizados e democráticos de coñecementos e prácticas que permitan modelos novos e sostibles no contexto rural. Segundo iso consideramos que o novo creativo transdisciplinar dos sectores nos que estamos enredados poden ter un impacto enorme e positivo na creación deste novo paradigma.<br />
https://bravosfoundry.com/ <br />
Ademais, hai un foco temático na transdisciplinariedade, o transfeminismo e o poshumanismo. Aínda que este enfoque non é axeitadamente comprendido por categorías políticas identitarias como a raza ou o xénero, esperamos que leve á subversión das estruturas hexemónicas inscritas nos binarismos que sosteñen moitas destas categorías. O noso interese reside no desenvolvemento de ferramentas e tecnoloxías que subvertan as estruturas contemporáneas de dominación, explotación e marxinación, non nas que a reproducen. Buscamos desenvolver un entorno máis sostible abrindo as nosas prácticas baseadas nun marco de cultura libre, xerando redes e interese ao seu redor, posibilitando un fluxo de intercambio de innovación entre sectores creativos centrados na revalorización dos contextos rurais e do seu patrimonio de coñecemento. <br />

=== '''Sección 2, implica a construción de pezas do '''alternador''' utilizando os dispositivos da sección 1.''' === <br />
<br />
'''Alternador''' Cada rotor magnético é un disco de aceiro con 12 imáns colocados sobre el e colocados en resina. Os imáns son cada un de 50 x 50 x 20 mm, e só caben no disco. A idea é conseguir a máxima cantidade de fluxo nun espazo determinado. A turbina funciona a 650 rpm para unha saída de 400 W, polo que a forza centrífuga sobre os imáns é 60 veces a forza da gravidade. Para evitar que saian voando, hai que reforzar a fundición de resina. Un cable de aceiro inoxidable colócase arredor da parte exterior dos imáns para manter a fundición xunta a altas revolucións por minuto. Usamos inoxidable porque non é magnético, ou polo menos menos magnético que un cable de aceiro normal. Enrolarás as bobinas que producen a potencia de saída e fundirase en resina para formar un estator entre os dous rotores magnéticos. <br />

<br />
Paso - Xerador, rotor: Preparación do disco metálico. fíxose a máquina na tenda [[File:prod05.jpg|200px]] <br />
Paso - Xerador, rotor: Preparación do cubo da roda. <br />
[[File:frame10.jpg|200px]] '''O cubo da roda''' Podes atopar un cubo de roda traseira de coche usado (Golf, Toyota, etc.) que teña un xeito sinxelo engade o eixe ou, alternativamente, compre un cubos de remolque en liña novos a baixo custo. PCD ou "diámetro do círculo de paso" é o diámetro do círculo do patrón do burato no cubo, e normalmente este será de 100 mm para un cubo de roda de coche, ou de 4 polgadas para un cubo de remolque. Os hubs dos coches poden ter un tambor de freo que non precisa. Isto pódese eliminar usando a disco de corte nunha moedora. O enfoque máis sinxelo é facer catro cortes rectos ao redor os catro orificios na parte frontal, deixando unha superficie cadrada na que se monta o imán rotores. Estas fotos mostran un cubo de roda traseira de golf: primeiro se corta o tambor de freo e a continuación, o cubo acabado despois de cortar o tambor. Un típico cubo de coche de roda traseira con a brida no extremo traseiro do eixe do tronco que se pode reutilizar para montalo. Os cubos de remolque, por outra banda, son de calidade bastante básica, e os rodamentos tamén poden ser barato para uso a longo prazo, pero son artigos facilmente dispoñibles que se poden mercar en liña como novo. Os debuxos que aparecen a continuación (de autow.com) mostran un concentrador e un stub típicos eixe que se compran por separado. Debe estar preparado para substituír os rodamentos por unha marca nomeada (como SKF). É fácil de substituír os conos e rolos internos, pero hai que golpear as capas exteriores suavemente fóra do cubo cunha deriva adecuada. Mantéñaos rectos tocando uniformemente lados opostos e teña coidado de non raiar o asento. Paso - Xerador, rotor: <br />

=== Sección 4, implica o modelado das palas e a soldadura da base para o xerador de turbina ===<br />
<br />
<br />
4.1 Fabricación das láminas. <br />
O coitelo é útil para anacos máis grosos de madeira e para cortar nun oco. Pode facer un bo traballo suave da raíz da lámina, mentres que o avión funcionará mellor onde necesitas un acabado moi recto. <br />
<br />
'''Marcando as estacións''' <br />
<br />
Coloque a folla co seu mellor bordo cara a vostede na súa superficie superior. Isto en realidade convértese na parte traseira ou "abaixo" da lámina acabada. (A maior parte do lado dianteiro ou de barlovento debe ser cortado, polo que hai defectos neste lado inferior non son importantes.)<br />
A raíz da folla estará á túa dereita, a punta á esquerda, a 1000 mm da raíz (preto do extremo esquerdo). Mide dende a raíz e marca catro estacións. Estación A a 75 mm Estación B a 150 mm Estación C a 500 mm A punta a 1000 mm. En cada estación debuxa unha liña ao redor da peza usando un cadrado. <br />
<br />
<br />
Agora debuxa a liña do bordo de ataque como se mostra a continuación, desde a estación B, ata 16 mm (desde atrás) na estación C, e despois continúa ata a punta en 7 mm de atrás. [[File:04tur.jpeg|400px]] <br />
<br />
(Este debuxo non mostra o bit extra máis aló da punta que pode quedar na súa peza de traballo real). As medidas resúmense nesta táboa a continuación. As alturas son dende a parte traseira folla que despois descansará no banco. Elimina a madeira por encima desta altura. "Cheo" refírese ao grosor total da peza de madeira orixinal que está a usar. <br />
[[File:05tur.jpeg|400px]]<br />
<br />
'''O rastro''' A liña do bordo posterior comeza na parte inferior da liña diagonal na estación B e sobe a 5 mm en C, continuando a 5 mm ata a punta. Esta vista abaixo mostra a madeira xa eliminado entre as dúas liñas para formar a cara barlovento da pala. <br />
<br />
[[File:06tur.png|400px]] <br />
<br />
Esculpe esta cara de barlovento plana entre as dúas liñas. Coida que os bordos estean recto, seguindo as liñas. A mellor ferramenta para usar para rematar a parte exterior do a lámina é un plano, para dar un acabado suave e recto. Quizais necesites traballar no avión 45 graos coa peza de traballo, deslizando parcialmente cara aos lados, para formar a forma oca en estación C. Este paso complétase cando podes colocar unha regra pola cara entre os principais e liñas de bordo de saída e non hai "xoroba" no medio. Encha calquera chip ou pequeno ocos con recheo de madeira. Se hai algún erro grave, ou k grande non que se debilitan a folla, entón pode ter que ser descartada. Comprobe a "caída" usando un nivel como referencia. Suxeitar a madeira para que a parte da raíz sitúase nivelado e mida a diferenza de nivel entre os bordos de entrada e de saída. A diferenza ou "caída" debe ser de 11 mm no punto medio de 500 mm e de 2 mm no punta. <br />

''Pedagoxías do vento e das estrelas. As relacións sociais ás que (nunca estabamos destinados) a sobrevivir, tamén viven nos nosos corpos dolorosamente, e Audre Lorde non está aquí para lembrarnos esta lección, salvo na medida en que está presente no vento pedagóxico. Pero o vento é o noso mestre (74). -Alexis Pauline Gumbs'' do libro Mapping Queer Space(s) of Praxis and Pedagogy Editores: Elizabeth McNeil, James E. Wermers, Joshua O. Lunn'' <br />
<br />
<br />
Temos o pracer de comunicarvos que do 16 ao 29 de outubro Pin Biotranslab, Casa do Río e The Foundry establece unha colaboración para levar a cabo o evento Eco (i) Logic Queer Energy harvesting. O proxecto é posible grazas ao apoio de GOSH, unha rede para desenvolver e difundir proxectos baseados en hardware de código aberto para a ciencia. '''Eco (i) Logic Queer Recollida de enerxía''' O evento ten como obxectivo abordar a falta de mulleres, queer, trans e diversidade nos ámbitos tecnolóxicos en xeral e do hacking máis concretamente. Pero aínda máis, pretende crear unha comunidade que avalía criticamente as narrativas hexemónicas arredor das tecnoloxías, os aspectos de modernidade dos seus supostos occidentais subliñados e as súas inflexións capitalistas inherentes, entre outros. O obxectivo principal do evento é desenvolver kits que se centren na interacción co medio natural no ámbito da enerxía.. o obxectivo principal pasa pola captación de enerxía do medio natural, a través dos aeroxeradores. Estes kits de enerxía serán escalables e poderán utilizarse tanto como material pedagóxico como para instalar centrais eléctricas específicas do sitio en diferentes sitios tamén. Este traballo ten un compoñente contrainfraestrutural: unha posible consecuencia sería capacitar ás persoas para xerar a súa propia enerxía en lugar de depender de grandes empresas e moitas veces extractivas. <br />
<br />
== Introdución e valores do proceso == <br />
<br />
Aquí comeza a documentación do longo proceso de creación de prototipos do modelo Hugh Piggott The Piggott Turbine - Wind Empowerment dunha turbina eólica de código aberto. Estivemos cambiando un pouco os obxectivos do evento, pasando de desenvolver pequenos kits para ir a construír o aeroxerador de 2 m de tamaño real para proporcionar enerxía ás áreas rexionais rurais nas que estabamos traballando. Nese evento concreto estivemos traballando en The Foundry un bonito proxecto e asociación que instalamos no norte de GaliZA ao noroeste de España. Durante o evento activáronse moitas cousas entre os realizadores e os visitantes; En xeral foi unha experiencia marabillosa chea de cousas novas que estudar, aprender, facer e comprender xuntos. Escollemos este modelo porque estaba cheo de capas de interese nos niveis de aprendizaxe, comprensión e elaboración, aquí algúns niveis mesturados con capas: en primeiro lugar é un dos que é '''de código aberto''' ou polo menos ten a opción de acceder á documentación completa. realmente '''ricos a nivel pedagóxico''', realmente estivemos aprendendo a través da construción completa do propio xerador, sobre moitos temas como: <br />
<br />
* electromagnetismo *matemáticas * xeometría * electrónica * AC-DC *soldadura * talla en madeira * escultura e fundición de pezas e moito máis que foi alcanzando a través do agradable proceso de ler, aprender e construír xuntos.<br />
<br />
== Glosario == <br />
* '''AC-'''Corrente alterna producida polo alternador. Todos os fíos: palabra estadounidense para varilla ou tachuelas "roscadas" ou "hiladas".<br />
* '''Interruptor de freo''' - Interruptor usado para curtocircuitar os cables do alternador para que se pare.<br />
* '''Catalizador''' - Un produto químico usado para facer sólido o conxunto de resinas de poliéster. O catalizador reacciona co "acelerador" xa presente na mestura de resina. A calor de reacción establece o poliéster.<br />
* '''Cavalier''' - Unha marca de coche. O cavalier no Reino Unido non é o mesmo que o Cavalier nos EUA, pero ambos teñen cubos de roda útiles.<br />
* '''DC - corrente continua''' cun lado positivo e outro negativo, como nos circuítos de batería.<br />
* '''Diámetro''' - A distancia dun lado a outro dun círculo. O ancho dun disco no medio.<br />
* '''Fase''' - O tempo da alternancia cíclica da tensión nun circuíto. As diferentes fases alcanzarán o pico en diferentes momentos.<br />
* '''Poliéster''' - Un tipo de resina utilizada no traballo de fibra de vidro. Tamén apto para facer fundicións.<br />
* '''Potencia''' - a taxa de entrega de enerxía<br />
* '''Rectifier''' - Un dispositivo semicondutor que converte AC en DC para cargar a batería.<br />
* '''Raíz''' - A parte máis ancha da lámina preto do cubo no centro do rotor.<br />
* '''Rotor''' - Unha parte xiratoria. Os rotores de imáns son os discos de aceiro que transportan os imáns máis alá do estator. As palas do rotor son a "hélice" impulsado polo vento e impulsando os rotores magnéticos.<br />
* '''Soldadura''': un método para facer conexións eléctricas entre fíos usando un 'ferro' quente e recubrindo todo con soldadura fundida.<br />
* '''Arrastre''' - Forza que exerce o vento sobre un obxecto. O arrastre é paralelo á dirección do vento no obxecto. (ver Ascensor)<br />
* '''Estator''' - Un conxunto de bobinas incrustadas nunha lousa de resina para formar parte do alternador. Os imáns inducen unha tensión nas bobinas e podemos utilizala para cargar unha batería. * '''Gota''': úsase aquí para describir unha determinada medida da forma da lámina dun muíño de vento. A "caída" afecta o ángulo de a lámina ao vento. Monómero de estireno - Un disolvente con cheiro desagradable na mestura de resina de poliéster.<br />
* '''Flux''' - As 'cousas' do magnetismo. Semellante á "corrente" na electricidade. Pódese visualizar como "liñas" que saen dun polo e volvendo ao outro.<br />
* '''Furling''' - Unha acción protectora que reduce a exposición a ventos violentos ao enfrontar as aspas lonxe delas.<br />
* '''Jig''' - Un dispositivo usado para manter os imáns no seu lugar antes de colocalos na resina.<br />
* '''Borde de ataque''' - O bordo dunha lámina que golpearía un obxecto colocado no seu camiño cando o rotor xira.<br />
* '''Elevación''' - Forza que exerce o vento sobre un obxecto. A sustentación está en ángulo recto coa dirección do vento no obxecto. (ver Arrastre)<br />
* '''Molde''' - Un recipiente con forma no que se forman fundicións de resina. O molde pódese descartar despois de que a fundición se fixera.<br />
* '''Multímetro''' - Un instrumento de proba eléctrico versátil, usado para medir tensión, corrente e outros parámetros.<br />
* '''Neodimio''' - O nome dado a un tipo de imán permanente que contén neodimio, ferro e boro. Estes imáns son moi fortes e cada vez máis barato.<br />
* '''Offset''' - Unha posición excéntrica, descentrada.<br />
* '''Po de talco'''- Un recheo en po barato que se usa para espesar a resina e retardar a súa reacción (evitar que se sobrequente).<br />
* '''Cola''': unha veleta que se sobresae montada nunha pluma na parte traseira do muíño de vento que se usa para dirixila ou fóra do vento automaticamente.<br />
* '''Tap''' - unha ferramenta para facer rosca dentro dos buratos para poder colocar un parafuso no burato.<br />
* '''Empuxe''' - A forza do vento que empurra a máquina cara atrás.<br />
* '''Torre''' - O mastro que soporta o muíño de vento.<br />
* '''Bordo posterior''': o bordo da lámina máis afastado do bordo de ataque. O bordo de saída está afiado, para liberar o paso aire sen turbulencias.<br />
* '''Cuñas''': pezas cónicas de madeira que se usan para aumentar o grosor da lámina e aumentar o seu ángulo co vento preto da raíz.<br />
* '''Peza de traballo''' - A peza de madeira ou metal que se está a dar forma no taller.<br />
* '''Colamento de guiñada''': o xiro da parte superior da torre na que está montado o muíño de vento. O rodamento de guiñada permite que o muíño se enfronte ao vento.<br />

<br />
A Fundición é unha organización sen ánimo de lucro con sede nunha aldea GaliZA anteriormente abandonada. Funciona tanto como residencia como como espazo de proxecto. Subscríbese aos ideais de autoorganización e ten os seguintes tres obxectivos: <br />
1. Organizar actividades no ámbito das artes, as ciencias e as humanidades fóra das institucións tradicionais, centradas no discurso crítico.<br />
2. Promover o intercambio de ideas e a colaboración intelectual fóra das limitacións impostas polo Estado e o mercado.<br />
3. Aumentar a autosuficiencia, a sustentabilidade e a concienciación co medio ambiente utilizando a tecnoloxía axeitada e o código aberto como principais recursos. Tendo en conta este contexto, o noso obxectivo é reforzar a capacidade de xerar redes que flúen do contexto rural ao urbano apoiando os intercambios non xerarquizados e democráticos de coñecementos e prácticas que permitan modelos novos e sostibles no contexto rural. Segundo iso consideramos que o novo creativo transdisciplinar dos sectores nos que estamos enredados poden ter un impacto enorme e positivo na creación deste novo paradigma.<br />
https://bravosfoundry.com/ <br />
Ademais, hai un foco temático na transdisciplinariedade, o transfeminismo e o poshumanismo. Aínda que este enfoque non é axeitadamente comprendido por categorías políticas identitarias como a raza ou o xénero, esperamos que leve á subversión das estruturas hexemónicas inscritas nos binarismos que sosteñen moitas destas categorías. O noso interese reside no desenvolvemento de ferramentas e tecnoloxías que subvertan as estruturas contemporáneas de dominación, explotación e marxinación, non nas que a reproducen. Buscamos desenvolver un entorno máis sostible abrindo as nosas prácticas baseadas nun marco de cultura libre, xerando redes e interese ao seu redor, posibilitando un fluxo de intercambio de innovación entre sectores creativos centrados na revalorización dos contextos rurais e do seu patrimonio de coñecemento. <br />

=== '''Sección 2, implica a construción de pezas do '''alternador''' utilizando os dispositivos da sección 1.''' === <br />
<br />
'''Alternador''' Cada rotor magnético é un disco de aceiro con 12 imáns colocados sobre el e colocados en resina. Os imáns son cada un de 50 x 50 x 20 mm, e só caben no disco. A idea é conseguir a máxima cantidade de fluxo nun espazo determinado. A turbina funciona a 650 rpm para unha saída de 400 W, polo que a forza centrífuga sobre os imáns é 60 veces a forza da gravidade. Para evitar que saian voando, hai que reforzar a fundición de resina. Un cable de aceiro inoxidable colócase arredor da parte exterior dos imáns para manter a fundición xunta a altas revolucións por minuto. Usamos inoxidable porque non é magnético, ou polo menos menos magnético que un cable de aceiro normal. Enrolarás as bobinas que producen a potencia de saída e fundirase en resina para formar un estator entre os dous rotores magnéticos. <br />

<br />
Paso - Xerador, rotor: Preparación do disco metálico. fíxose a máquina na tenda [[File:prod05.jpg|200px]] <br />
Paso - Xerador, rotor: Preparación do cubo da roda. <br />
[[File:frame10.jpg|200px]] '''O cubo da roda''' Podes atopar un cubo de roda traseira de coche usado (Golf, Toyota, etc.) que teña un xeito sinxelo engade o eixe ou, alternativamente, compre un cubos de remolque en liña novos a baixo custo. PCD ou "diámetro do círculo de paso" é o diámetro do círculo do patrón do burato no cubo, e normalmente este será de 100 mm para un cubo de roda de coche, ou de 4 polgadas para un cubo de remolque. Os hubs dos coches poden ter un tambor de freo que non precisa. Isto pódese eliminar usando a disco de corte nunha moedora. O enfoque máis sinxelo é facer catro cortes rectos ao redor os catro orificios na parte frontal, deixando unha superficie cadrada na que se monta o imán rotores. Estas fotos mostran un cubo de roda traseira de golf: primeiro se corta o tambor de freo e a continuación, o cubo acabado despois de cortar o tambor. Un típico cubo de coche de roda traseira con a brida no extremo traseiro do eixe do tronco que se pode reutilizar para montalo. Os cubos de remolque, por outra banda, son de calidade bastante básica, e os rodamentos tamén poden ser barato para uso a longo prazo, pero son artigos facilmente dispoñibles que se poden mercar en liña como novo. Os debuxos que aparecen a continuación (de autow.com) mostran un concentrador e un stub típicos eixe que se compran por separado. Debe estar preparado para substituír os rodamentos por unha marca nomeada (como SKF). É fácil de substituír os conos e rolos internos, pero hai que golpear as capas exteriores suavemente fóra do cubo cunha deriva adecuada. Mantéñaos rectos tocando uniformemente lados opostos e teña coidado de non raiar o asento. Paso - Xerador, rotor: <br />

=== Sección 4, implica o modelado das palas e a soldadura da base para o xerador de turbina ===<br />
<br />
<br />
4.1 Fabricación das láminas. <br />
O coitelo é útil para anacos máis grosos de madeira e para cortar nun oco. Pode facer un bo traballo suave da raíz da lámina, mentres que o avión funcionará mellor onde necesitas un acabado moi recto. <br />
<br />
'''Marcando as estacións''' <br />
<br />
Coloque a folla co seu mellor bordo cara a vostede na súa superficie superior. Isto en realidade convértese na parte traseira ou "abaixo" da lámina acabada. (A maior parte do lado dianteiro ou de barlovento debe ser cortado, polo que hai defectos neste lado inferior non son importantes.)<br />
A raíz da folla estará á túa dereita, a punta á esquerda, a 1000 mm da raíz (preto do extremo esquerdo). Mide dende a raíz e marca catro estacións. Estación A a 75 mm Estación B a 150 mm Estación C a 500 mm A punta a 1000 mm. En cada estación debuxa unha liña ao redor da peza usando un cadrado. <br />
<br />
<br />
Agora debuxa a liña do bordo de ataque como se mostra a continuación, desde a estación B, ata 16 mm (desde atrás) na estación C, e despois continúa ata a punta en 7 mm de atrás. [[File:04tur.jpeg|400px]] <br />
<br />
(Este debuxo non mostra o bit extra máis aló da punta que pode quedar na súa peza de traballo real). As medidas resúmense nesta táboa a continuación. As alturas son dende a parte traseira folla que despois descansará no banco. Elimina a madeira por encima desta altura. "Cheo" refírese ao grosor total da peza de madeira orixinal que está a usar. <br />
[[File:05tur.jpeg|400px]]<br />
<br />
'''O rastro''' A liña do bordo posterior comeza na parte inferior da liña diagonal na estación B e sobe a 5 mm en C, continuando a 5 mm ata a punta. Esta vista abaixo mostra a madeira xa eliminado entre as dúas liñas para formar a cara barlovento da pala. <br />
<br />
[[File:06tur.png|400px]] <br />
<br />
Esculpe esta cara de barlovento plana entre as dúas liñas. Coida que os bordos estean recto, seguindo as liñas. A mellor ferramenta para usar para rematar a parte exterior do a lámina é un plano, para dar un acabado suave e recto. Quizais necesites traballar no avión 45 graos coa peza de traballo, deslizando parcialmente cara aos lados, para formar a forma oca en estación C. Este paso complétase cando podes colocar unha regra pola cara entre os principais e liñas de bordo de saída e non hai "xoroba" no medio. Encha calquera chip ou pequeno ocos con recheo de madeira. Se hai algún erro grave, ou k grande non que se debilitan a folla, entón pode ter que ser descartada. Comprobe a "caída" usando un nivel como referencia. Suxeitar a madeira para que a parte da raíz sitúase nivelado e mida a diferenza de nivel entre os bordos de entrada e de saída. A diferenza ou "caída" debe ser de 11 mm no punto medio de 500 mm e de 2 mm no punta. <br />

''Pedagoxías do vento e das estrelas. As relacións sociais ás que (nunca estabamos destinados) a sobrevivir, tamén viven nos nosos corpos dolorosamente, e Audre Lorde non está aquí para lembrarnos esta lección, salvo na medida en que está presente no vento pedagóxico. Pero o vento é o noso mestre (74). -Alexis Pauline Gumbs'' do libro Mapping Queer Space(s) of Praxis and Pedagogy Editores: Elizabeth McNeil, James E. Wermers, Joshua O. Lunn'' <br />
<br />
<br />
Temos o pracer de comunicarvos que do 16 ao 29 de outubro Pin Biotranslab, Casa do Río e The Foundry establece unha colaboración para levar a cabo o evento Eco (i) Logic Queer Energy harvesting. O proxecto é posible grazas ao apoio de GOSH, unha rede para desenvolver e difundir proxectos baseados en hardware de código aberto para a ciencia. '''Eco (i) Logic Queer Recollida de enerxía''' O evento ten como obxectivo abordar a falta de mulleres, queer, trans e diversidade nos ámbitos tecnolóxicos en xeral e do hacking máis concretamente. Pero aínda máis, pretende crear unha comunidade que avalía criticamente as narrativas hexemónicas arredor das tecnoloxías, os aspectos de modernidade dos seus supostos occidentais subliñados e as súas inflexións capitalistas inherentes, entre outros. O obxectivo principal do evento é desenvolver kits que se centren na interacción co medio natural no ámbito da enerxía.. o obxectivo principal pasa pola captación de enerxía do medio natural, a través dos aeroxeradores. Estes kits de enerxía serán escalables e poderán utilizarse tanto como material pedagóxico como para instalar centrais eléctricas específicas do sitio en diferentes sitios tamén. Este traballo ten un compoñente contrainfraestrutural: unha posible consecuencia sería capacitar ás persoas para xerar a súa propia enerxía en lugar de depender de grandes empresas e moitas veces extractivas. <br />
<br />
== Introdución e valores do proceso == <br />
<br />
Aquí comeza a documentación do longo proceso de creación de prototipos do modelo Hugh Piggott The Piggott Turbine - Wind Empowerment dunha turbina eólica de código aberto. Estivemos cambiando un pouco os obxectivos do evento, pasando de desenvolver pequenos kits para ir a construír o aeroxerador de 2 m de tamaño real para proporcionar enerxía ás áreas rexionais rurais nas que estabamos traballando. Nese evento concreto estivemos traballando en The Foundry un bonito proxecto e asociación que instalamos no norte de GaliZA ao noroeste de España. Durante o evento activáronse moitas cousas entre os realizadores e os visitantes; En xeral foi unha experiencia marabillosa chea de cousas novas que estudar, aprender, facer e comprender xuntos. Escollemos este modelo porque estaba cheo de capas de interese nos niveis de aprendizaxe, comprensión e elaboración, aquí algúns niveis mesturados con capas: en primeiro lugar é un dos que é '''de código aberto''' ou polo menos ten a opción de acceder á documentación completa. realmente '''ricos a nivel pedagóxico''', realmente estivemos aprendendo a través da construción completa do propio xerador, sobre moitos temas como: <br />
<br />
* electromagnetismo *matemáticas * xeometría * electrónica * AC-DC *soldadura * talla en madeira * escultura e fundición de pezas e moito máis que foi alcanzando a través do agradable proceso de ler, aprender e construír xuntos.<br />
<br />
== Glosario == <br />
* '''AC-'''Corrente alterna producida polo alternador. Todos os fíos: palabra estadounidense para varilla ou tachuelas "roscadas" ou "hiladas".<br />
* '''Interruptor de freo''' - Interruptor usado para curtocircuitar os cables do alternador para que se pare.<br />
* '''Catalizador''' - Un produto químico usado para facer sólido o conxunto de resinas de poliéster. O catalizador reacciona co "acelerador" xa presente na mestura de resina. A calor de reacción establece o poliéster.<br />
* '''Cavalier''' - Unha marca de coche. O cavalier no Reino Unido non é o mesmo que o Cavalier nos EUA, pero ambos teñen cubos de roda útiles.<br />
* '''DC - corrente continua''' cun lado positivo e outro negativo, como nos circuítos de batería.<br />
* '''Diámetro''' - A distancia dun lado a outro dun círculo. O ancho dun disco no medio.<br />
* '''Fase''' - O tempo da alternancia cíclica da tensión nun circuíto. As diferentes fases alcanzarán o pico en diferentes momentos.<br />
* '''Poliéster''' - Un tipo de resina utilizada no traballo de fibra de vidro. Tamén apto para facer fundicións.<br />
* '''Potencia''' - a taxa de entrega de enerxía<br />
* '''Rectifier''' - Un dispositivo semicondutor que converte AC en DC para cargar a batería.<br />
* '''Raíz''' - A parte máis ancha da lámina preto do cubo no centro do rotor.<br />
* '''Rotor''' - Unha parte xiratoria. Os rotores de imáns son os discos de aceiro que transportan os imáns máis alá do estator. As palas do rotor son a "hélice" impulsado polo vento e impulsando os rotores magnéticos.<br />
* '''Soldadura''': un método para facer conexións eléctricas entre fíos usando un 'ferro' quente e recubrindo todo con soldadura fundida.<br />
* '''Arrastre''' - Forza que exerce o vento sobre un obxecto. O arrastre é paralelo á dirección do vento no obxecto. (ver Ascensor)<br />
* '''Estator''' - Un conxunto de bobinas incrustadas nunha lousa de resina para formar parte do alternador. Os imáns inducen unha tensión nas bobinas e podemos utilizala para cargar unha batería. * '''Gota''': úsase aquí para describir unha determinada medida da forma da lámina dun muíño de vento. A "caída" afecta o ángulo de a lámina ao vento. Monómero de estireno - Un disolvente con cheiro desagradable na mestura de resina de poliéster.<br />
* '''Flux''' - As 'cousas' do magnetismo. Semellante á "corrente" na electricidade. Pódese visualizar como "liñas" que saen dun polo e volvendo ao outro.<br />
* '''Furling''' - Unha acción protectora que reduce a exposición a ventos violentos ao enfrontar as aspas lonxe delas.<br />
* '''Jig''' - Un dispositivo usado para manter os imáns no seu lugar antes de colocalos na resina.<br />
* '''Borde de ataque''' - O bordo dunha lámina que golpearía un obxecto colocado no seu camiño cando o rotor xira.<br />
* '''Elevación''' - Forza que exerce o vento sobre un obxecto. A sustentación está en ángulo recto coa dirección do vento no obxecto. (ver Arrastre)<br />
* '''Molde''' - Un recipiente con forma no que se forman fundicións de resina. O molde pódese descartar despois de que a fundición se fixera.<br />
* '''Multímetro''' - Un instrumento de proba eléctrico versátil, usado para medir tensión, corrente e outros parámetros.<br />
* '''Neodimio''' - O nome dado a un tipo de imán permanente que contén neodimio, ferro e boro. Estes imáns son moi fortes e cada vez máis barato.<br />
* '''Offset''' - Unha posición excéntrica, descentrada.<br />
* '''Po de talco'''- Un recheo en po barato que se usa para espesar a resina e retardar a súa reacción (evitar que se sobrequente).<br />
* '''Cola''': unha veleta que se sobresae montada nunha pluma na parte traseira do muíño de vento que se usa para dirixila ou fóra do vento automaticamente.<br />
* '''Tap''' - unha ferramenta para facer rosca dentro dos buratos para poder colocar un parafuso no burato.<br />
* '''Empuxe''' - A forza do vento que empurra a máquina cara atrás.<br />
* '''Torre''' - O mastro que soporta o muíño de vento.<br />
* '''Bordo posterior''': o bordo da lámina máis afastado do bordo de ataque. O bordo de saída está afiado, para liberar o paso aire sen turbulencias.<br />
* '''Cuñas''': pezas cónicas de madeira que se usan para aumentar o grosor da lámina e aumentar o seu ángulo co vento preto da raíz.<br />
* '''Peza de traballo''' - A peza de madeira ou metal que se está a dar forma no taller.<br />
* '''Colamento de guiñada''': o xiro da parte superior da torre na que está montado o muíño de vento. O rodamento de guiñada permite que o muíño se enfronte ao vento.<br />

=== A fundición === <br />
<br />
A Fundición é unha organización sen ánimo de lucro con sede nunha aldea GaliZA anteriormente abandonada. Funciona tanto como residencia como como espazo de proxecto. Subscríbese aos ideais de autoorganización e ten os seguintes tres obxectivos: <br />
1. Organizar actividades no ámbito das artes, as ciencias e as humanidades fóra das institucións tradicionais, centradas no discurso crítico.<br />
2. Promover o intercambio de ideas e a colaboración intelectual fóra das limitacións impostas polo Estado e o mercado.<br />
3. Aumentar a autosuficiencia, a sustentabilidade e a concienciación co medio ambiente utilizando a tecnoloxía axeitada e o código aberto como principais recursos. Tendo en conta este contexto, o noso obxectivo é reforzar a capacidade de xerar redes que flúen do contexto rural ao urbano apoiando os intercambios non xerarquizados e democráticos de coñecementos e prácticas que permitan modelos novos e sostibles no contexto rural. Segundo iso consideramos que o novo creativo transdisciplinar dos sectores nos que estamos enredados poden ter un impacto enorme e positivo na creación deste novo paradigma.<br />
https://bravosfoundry.com/ <br />
Ademais, hai un foco temático na transdisciplinariedade, o transfeminismo e o poshumanismo. Aínda que este enfoque non é axeitadamente comprendido por categorías políticas identitarias como a raza ou o xénero, esperamos que leve á subversión das estruturas hexemónicas inscritas nos binarismos que sosteñen moitas destas categorías. O noso interese reside no desenvolvemento de ferramentas e tecnoloxías que subvertan as estruturas contemporáneas de dominación, explotación e marxinación, non nas que a reproducen. Buscamos desenvolver un entorno máis sostible abrindo as nosas prácticas baseadas nun marco de cultura libre, xerando redes e interese ao seu redor, posibilitando un fluxo de intercambio de innovación entre sectores creativos centrados na revalorización dos contextos rurais e do seu patrimonio de coñecemento. <br />

=== '''Sección 2, implica a construción de pezas do '''alternador''' utilizando os dispositivos da sección 1.''' === <br />
<br />
'''Alternador''' Cada rotor magnético é un disco de aceiro con 12 imáns colocados sobre el e colocados en resina. Os imáns son cada un de 50 x 50 x 20 mm, e só caben no disco. A idea é conseguir a máxima cantidade de fluxo nun espazo determinado. A turbina funciona a 650 rpm para unha saída de 400 W, polo que a forza centrífuga sobre os imáns é 60 veces a forza da gravidade. Para evitar que saian voando, hai que reforzar a fundición de resina. Un cable de aceiro inoxidable colócase arredor da parte exterior dos imáns para manter a fundición xunta a altas revolucións por minuto. Usamos inoxidable porque non é magnético, ou polo menos menos magnético que un cable de aceiro normal. Enrolarás as bobinas que producen a potencia de saída e fundirase en resina para formar un estator entre os dous rotores magnéticos. <br />

=== Sección 3, implica a creación da parte do rotor do xerador: === <br />
<br />
Paso - Xerador, rotor: Preparación do disco metálico. fíxose a máquina na tenda [[File:prod05.jpg|200px]] <br />
Paso - Xerador, rotor: Preparación do cubo da roda. <br />
[[File:frame10.jpg|200px]] '''O cubo da roda''' Podes atopar un cubo de roda traseira de coche usado (Golf, Toyota, etc.) que teña un xeito sinxelo engade o eixe ou, alternativamente, compre un cubos de remolque en liña novos a baixo custo. PCD ou "diámetro do círculo de paso" é o diámetro do círculo do patrón do burato no cubo, e normalmente este será de 100 mm para un cubo de roda de coche, ou de 4 polgadas para un cubo de remolque. Os hubs dos coches poden ter un tambor de freo que non precisa. Isto pódese eliminar usando a disco de corte nunha moedora. O enfoque máis sinxelo é facer catro cortes rectos ao redor os catro orificios na parte frontal, deixando unha superficie cadrada na que se monta o imán rotores. Estas fotos mostran un cubo de roda traseira de golf: primeiro se corta o tambor de freo e a continuación, o cubo acabado despois de cortar o tambor. Un típico cubo de coche de roda traseira con a brida no extremo traseiro do eixe do tronco que se pode reutilizar para montalo. Os cubos de remolque, por outra banda, son de calidade bastante básica, e os rodamentos tamén poden ser barato para uso a longo prazo, pero son artigos facilmente dispoñibles que se poden mercar en liña como novo. Os debuxos que aparecen a continuación (de autow.com) mostran un concentrador e un stub típicos eixe que se compran por separado. Debe estar preparado para substituír os rodamentos por unha marca nomeada (como SKF). É fácil de substituír os conos e rolos internos, pero hai que golpear as capas exteriores suavemente fóra do cubo cunha deriva adecuada. Mantéñaos rectos tocando uniformemente lados opostos e teña coidado de non raiar o asento. Paso - Xerador, rotor: Preparación da plantilla. <br />

=== Sección 4, implica o modelado das palas e a soldadura da base para o xerador de turbina === <br />
<br />
4.1 Fabricación das láminas O coitelo é útil para anacos máis grosos de madeira e para cortar nun oco. Pode facer un bo traballo suave da raíz da lámina, mentres que o avión funcionará mellor onde necesitas un acabado moi recto. '''Marcando as estacións''' Coloque a folla co seu mellor bordo cara a vostede na súa superficie superior. Isto en realidade convértese na parte traseira ou "abaixo" da lámina acabada. (A maior parte do lado dianteiro ou de barlovento debe ser cortado, polo que hai defectos neste lado inferior non son importantes.) A raíz da folla estará á túa dereita, a punta á esquerda, a 1000 mm da raíz (preto do extremo esquerdo). Mide dende a raíz e marca catro estacións. Estación A a 75 mm Estación B a 150 mm Estación C a 500 mm A punta a 1000 mm. En cada estación debuxa unha liña ao redor da peza usando un cadrado. <br />
<br />
[[File:01tur.jpeg|400px]]<br />
<br />
<br />
'''Afilando a folla''' O ancho da folla diminúe desde o tamaño completo na estación C ata 55 mm de ancho na estación punta. Marque o ancho da punta de 55 mm, medindo dende o lado do bordo de ataque. Debuxa unha liña aínda que a túa marca ao lado do bordo posterior na estación C e corta unha peza triangular así como para conseguir a forma cónica correcta para a folla. Calquera nós no triangular o corte non importa xa que esta peza é descartada. Tenta facer este corte "cadrado", perpendicular á superficie posterior da lámina. Podes facelo cunha serra circular ou cortando e afeitando transversalmente como se describe arriba.<br />
<br />
[[File:02tur.jpeg|400px]] <br />
<br />
'''Marcando os bordos de entrada e de saída''' O seguinte paso é cortar a cara de barlovento da lámina. Esta cara está definida polo liñas de bordo de ataque e de saída da lámina. Estas liñas deben estar marcadas con referencia á cara posterior da madeira que estivo máis arriba na anterior operación. Darlle a volta á madeira. Comeza trazando dúas liñas diagonais entre as estacións A e B na parte dianteira ou a barlovento (ver máis abaixo). Un está na cara frontal e o outro na cara o bordo de saída que agora está cara a ti. <br />
<br />
[[File:03tur.jpeg|400px]] <br />
<br />
Agora debuxa a liña do bordo de ataque como se mostra a continuación, desde a estación B, ata 16 mm (desde atrás) na estación C, e despois continúa ata a punta en 7 mm de atrás. [[File:04tur.jpeg|400px]] <br />
<br />
(Este debuxo non mostra o bit extra máis aló da punta que pode quedar na súa peza de traballo real). As medidas resúmense nesta táboa a continuación. As alturas son dende a parte traseira folla que despois descansará no banco. Elimina a madeira por encima desta altura. "Cheo" refírese ao grosor total da peza de madeira orixinal que está a usar. [[File:05tur.jpeg|400px]] '''O rastro''' A liña do bordo posterior comeza na parte inferior da liña diagonal na estación B e sobe a 5 mm en C, continuando a 5 mm ata a punta. Esta vista abaixo mostra a madeira xa eliminado entre as dúas liñas para formar a cara barlovento da pala. <br />
<br />
[[File:06tur.png|400px]] <br />
<br />
Esculpe esta cara de barlovento plana entre as dúas liñas. Coida que os bordos estean recto, seguindo as liñas. A mellor ferramenta para usar para rematar a parte exterior do a lámina é un plano, para dar un acabado suave e recto. Quizais necesites traballar no avión 45 graos coa peza de traballo, deslizando parcialmente cara aos lados, para formar a forma oca en estación C. Este paso complétase cando podes colocar unha regra pola cara entre os principais e liñas de bordo de saída e non hai "xoroba" no medio. Encha calquera chip ou pequeno ocos con recheo de madeira. Se hai algún erro grave, ou k grande non que se debilitan a folla, entón pode ter que ser descartada. Comprobe a "caída" usando un nivel como referencia. Suxeitar a madeira para que a parte da raíz sitúase nivelado e mida a diferenza de nivel entre os bordos de entrada e de saída. A diferenza ou "caída" debe ser de 11 mm no punto medio de 500 mm e de 2 mm no punta. <br />

''Pedagoxías do vento e das estrelas. As relacións sociais ás que (nunca estabamos destinados) a sobrevivir, tamén viven nos nosos corpos dolorosamente, e Audre Lorde non está aquí para lembrarnos esta lección, salvo na medida en que está presente no vento pedagóxico. Pero o vento é o noso mestre (74). -Alexis Pauline Gumbs'' do libro Mapping Queer Space(s) of Praxis and Pedagogy Editores: Elizabeth McNeil, James E. Wermers, Joshua O. Lunn'' <br />
<br />
<br />
Temos o pracer de comunicarvos que do 16 ao 29 de outubro Pin Biotranslab, Casa do Río e The Foundry establece unha colaboración para levar a cabo o evento Eco (i) Logic Queer Energy harvesting. O proxecto é posible grazas ao apoio de GOSH, unha rede para desenvolver e difundir proxectos baseados en hardware de código aberto para a ciencia. '''Eco (i) Logic Queer Recollida de enerxía''' O evento ten como obxectivo abordar a falta de mulleres, queer, trans e diversidade nos ámbitos tecnolóxicos en xeral e do hacking máis concretamente. Pero aínda máis, pretende crear unha comunidade que avalía criticamente as narrativas hexemónicas arredor das tecnoloxías, os aspectos de modernidade dos seus supostos occidentais subliñados e as súas inflexións capitalistas inherentes, entre outros. O obxectivo principal do evento é desenvolver kits que se centren na interacción co medio natural no ámbito da enerxía.. o obxectivo principal pasa pola captación de enerxía do medio natural, a través dos aeroxeradores. Estes kits de enerxía serán escalables e poderán utilizarse tanto como material pedagóxico como para instalar centrais eléctricas específicas do sitio en diferentes sitios tamén. Este traballo ten un compoñente contrainfraestrutural: unha posible consecuencia sería capacitar ás persoas para xerar a súa propia enerxía en lugar de depender de grandes empresas e moitas veces extractivas. <br />
<br />
== Introdución e valores do proceso == <br />
<br />
Aquí comeza a documentación do longo proceso de creación de prototipos do modelo Hugh Piggott The Piggott Turbine - Wind Empowerment dunha turbina eólica de código aberto. Estivemos cambiando un pouco os obxectivos do evento, pasando de desenvolver pequenos kits para ir a construír o aeroxerador de 2 m de tamaño real para proporcionar enerxía ás áreas rexionais rurais nas que estabamos traballando. Nese evento concreto estivemos traballando en The Foundry un bonito proxecto e asociación que instalamos no norte de GaliZA ao noroeste de España. Durante o evento activáronse moitas cousas entre os realizadores e os visitantes; En xeral foi unha experiencia marabillosa chea de cousas novas que estudar, aprender, facer e comprender xuntos. Escollemos este modelo porque estaba cheo de capas de interese nos niveis de aprendizaxe, comprensión e elaboración, aquí algúns niveis mesturados con capas: en primeiro lugar é un dos que é '''de código aberto''' ou polo menos ten a opción de acceder á documentación completa. realmente '''ricos a nivel pedagóxico''', realmente estivemos aprendendo a través da construción completa do propio xerador, sobre moitos temas como: <br />
<br />
* electromagnetismo *matemáticas * xeometría * electrónica * AC-DC *soldadura * talla en madeira * escultura e fundición de pezas e moito máis que foi alcanzando a través do agradable proceso de ler, aprender e construír xuntos.<br />
<br />
== Glosario == <br />
* '''AC-'''Corrente alterna producida polo alternador. Todos os fíos: palabra estadounidense para varilla ou tachuelas "roscadas" ou "hiladas".<br />
* '''Interruptor de freo''' - Interruptor usado para curtocircuitar os cables do alternador para que se pare.<br />
* '''Catalizador''' - Un produto químico usado para facer sólido o conxunto de resinas de poliéster. O catalizador reacciona co "acelerador" xa presente na mestura de resina. A calor de reacción establece o poliéster.<br />
* '''Cavalier''' - Unha marca de coche. O cavalier no Reino Unido non é o mesmo que o Cavalier nos EUA, pero ambos teñen cubos de roda útiles.<br />
* '''DC - corrente continua''' cun lado positivo e outro negativo, como nos circuítos de batería.<br />
* '''Diámetro''' - A distancia dun lado a outro dun círculo. O ancho dun disco no medio.<br />
* '''Fase''' - O tempo da alternancia cíclica da tensión nun circuíto. As diferentes fases alcanzarán o pico en diferentes momentos.<br />
* '''Poliéster''' - Un tipo de resina utilizada no traballo de fibra de vidro. Tamén apto para facer fundicións.<br />
* '''Potencia''' - a taxa de entrega de enerxía<br />
* '''Rectifier''' - Un dispositivo semicondutor que converte AC en DC para cargar a batería.<br />
* '''Raíz''' - A parte máis ancha da lámina preto do cubo no centro do rotor.<br />
* '''Rotor''' - Unha parte xiratoria. Os rotores de imáns son os discos de aceiro que transportan os imáns máis alá do estator. As palas do rotor son a "hélice" impulsado polo vento e impulsando os rotores magnéticos.<br />
* '''Soldadura''': un método para facer conexións eléctricas entre fíos usando un 'ferro' quente e recubrindo todo con soldadura fundida.<br />
* '''Arrastre''' - Forza que exerce o vento sobre un obxecto. O arrastre é paralelo á dirección do vento no obxecto. (ver Ascensor)<br />
* '''Estator''' - Un conxunto de bobinas incrustadas nunha lousa de resina para formar parte do alternador. Os imáns inducen unha tensión nas bobinas e podemos utilizala para cargar unha batería. * '''Gota''': úsase aquí para describir unha determinada medida da forma da lámina dun muíño de vento. A "caída" afecta o ángulo de a lámina ao vento. Monómero de estireno - Un disolvente con cheiro desagradable na mestura de resina de poliéster.<br />
* '''Flux''' - As 'cousas' do magnetismo. Semellante á "corrente" na electricidade. Pódese visualizar como "liñas" que saen dun polo e volvendo ao outro.<br />
* '''Furling''' - Unha acción protectora que reduce a exposición a ventos violentos ao enfrontar as aspas lonxe delas.<br />
* '''Jig''' - Un dispositivo usado para manter os imáns no seu lugar antes de colocalos na resina.<br />
* '''Borde de ataque''' - O bordo dunha lámina que golpearía un obxecto colocado no seu camiño cando o rotor xira.<br />
* '''Elevación''' - Forza que exerce o vento sobre un obxecto. A sustentación está en ángulo recto coa dirección do vento no obxecto. (ver Arrastre)<br />
* '''Molde''' - Un recipiente con forma no que se forman fundicións de resina. O molde pódese descartar despois de que a fundición se fixera.<br />
* '''Multímetro''' - Un instrumento de proba eléctrico versátil, usado para medir tensión, corrente e outros parámetros.<br />
* '''Neodimio''' - O nome dado a un tipo de imán permanente que contén neodimio, ferro e boro. Estes imáns son moi fortes e cada vez máis barato.<br />
* '''Offset''' - Unha posición excéntrica, descentrada.<br />
* '''Po de talco'''- Un recheo en po barato que se usa para espesar a resina e retardar a súa reacción (evitar que se sobrequente).<br />
* '''Cola''': unha veleta que se sobresae montada nunha pluma na parte traseira do muíño de vento que se usa para dirixila ou fóra do vento automaticamente.<br />
* '''Tap''' - unha ferramenta para facer rosca dentro dos buratos para poder colocar un parafuso no burato.<br />
* '''Empuxe''' - A forza do vento que empurra a máquina cara atrás.<br />
* '''Torre''' - O mastro que soporta o muíño de vento.<br />
* '''Bordo posterior''': o bordo da lámina máis afastado do bordo de ataque. O bordo de saída está afiado, para liberar o paso aire sen turbulencias.<br />
* '''Cuñas''': pezas cónicas de madeira que se usan para aumentar o grosor da lámina e aumentar o seu ángulo co vento preto da raíz.<br />
* '''Peza de traballo''' - A peza de madeira ou metal que se está a dar forma no taller.<br />
* '''Colamento de guiñada''': o xiro da parte superior da torre na que está montado o muíño de vento. O rodamento de guiñada permite que o muíño se enfronte ao vento.<br />

=== A fundición === <br />
<br />
A Fundición é unha organización sen ánimo de lucro con sede nunha aldea GaliZA anteriormente abandonada. Funciona tanto como residencia como como espazo de proxecto. Subscríbese aos ideais de autoorganización e ten os seguintes tres obxectivos: <br />
1. Organizar actividades no ámbito das artes, as ciencias e as humanidades fóra das institucións tradicionais, centradas no discurso crítico.<br />
2. Promover o intercambio de ideas e a colaboración intelectual fóra das limitacións impostas polo Estado e o mercado.<br />
3. Aumentar a autosuficiencia, a sustentabilidade e a concienciación co medio ambiente utilizando a tecnoloxía axeitada e o código aberto como principais recursos. Tendo en conta este contexto, o noso obxectivo é reforzar a capacidade de xerar redes que flúen do contexto rural ao urbano apoiando os intercambios non xerarquizados e democráticos de coñecementos e prácticas que permitan modelos novos e sostibles no contexto rural. Segundo iso consideramos que o novo creativo transdisciplinar dos sectores nos que estamos enredados poden ter un impacto enorme e positivo na creación deste novo paradigma.<br />
https://bravosfoundry.com/ <br />
Ademais, hai un foco temático na transdisciplinariedade, o transfeminismo e o poshumanismo. Aínda que este enfoque non é axeitadamente comprendido por categorías políticas identitarias como a raza ou o xénero, esperamos que leve á subversión das estruturas hexemónicas inscritas nos binarismos que sosteñen moitas destas categorías. O noso interese reside no desenvolvemento de ferramentas e tecnoloxías que subvertan as estruturas contemporáneas de dominación, explotación e marxinación, non nas que a reproducen. Buscamos desenvolver un entorno máis sostible abrindo as nosas prácticas baseadas nun marco de cultura libre, xerando redes e interese ao seu redor, posibilitando un fluxo de intercambio de innovación entre sectores creativos centrados na revalorización dos contextos rurais e do seu patrimonio de coñecemento. <br />

=== '''Sección 2, implica a construción de pezas do '''alternador''' utilizando os dispositivos da sección 1.''' === <br />
<br />
'''Alternador''' Cada rotor magnético é un disco de aceiro con 12 imáns colocados sobre el e colocados en resina. Os imáns son cada un de 50 x 50 x 20 mm, e só caben no disco. A idea é conseguir a máxima cantidade de fluxo nun espazo determinado. A turbina funciona a 650 rpm para unha saída de 400 W, polo que a forza centrífuga sobre os imáns é 60 veces a forza da gravidade. Para evitar que saian voando, hai que reforzar a fundición de resina. Un cable de aceiro inoxidable colócase arredor da parte exterior dos imáns para manter a fundición xunta a altas revolucións por minuto. Usamos inoxidable porque non é magnético, ou polo menos menos magnético que un cable de aceiro normal. Enrolarás as bobinas que producen a potencia de saída e fundirase en resina para formar un estator entre os dous rotores magnéticos. <br />

=== Sección 3, implica a creación da parte do rotor do xerador: === <br />
<br />
Paso - Xerador, rotor: Preparación do disco metálico. fíxose a máquina na tenda [[File:prod05.jpg|200px]] <br />
Paso - Xerador, rotor: Preparación do cubo da roda. <br />
[[File:frame10.jpg|200px]] '''O cubo da roda''' Podes atopar un cubo de roda traseira de coche usado (Golf, Toyota, etc.) que teña un xeito sinxelo engade o eixe ou, alternativamente, compre un cubos de remolque en liña novos a baixo custo. PCD ou "diámetro do círculo de paso" é o diámetro do círculo do patrón do burato no cubo, e normalmente este será de 100 mm para un cubo de roda de coche, ou de 4 polgadas para un cubo de remolque. Os hubs dos coches poden ter un tambor de freo que non precisa. Isto pódese eliminar usando a disco de corte nunha moedora. O enfoque máis sinxelo é facer catro cortes rectos ao redor os catro orificios na parte frontal, deixando unha superficie cadrada na que se monta o imán rotores. Estas fotos mostran un cubo de roda traseira de golf: primeiro se corta o tambor de freo e a continuación, o cubo acabado despois de cortar o tambor. Un típico cubo de coche de roda traseira con a brida no extremo traseiro do eixe do tronco que se pode reutilizar para montalo. Os cubos de remolque, por outra banda, son de calidade bastante básica, e os rodamentos tamén poden ser barato para uso a longo prazo, pero son artigos facilmente dispoñibles que se poden mercar en liña como novo. Os debuxos que aparecen a continuación (de autow.com) mostran un concentrador e un stub típicos eixe que se compran por separado. Debe estar preparado para substituír os rodamentos por unha marca nomeada (como SKF). É fácil de substituír os conos e rolos internos, pero hai que golpear as capas exteriores suavemente fóra do cubo cunha deriva adecuada. Mantéñaos rectos tocando uniformemente lados opostos e teña coidado de non raiar o asento. Paso - Xerador, rotor: Preparación da plantilla. <br />

=== Sección 4, implica o modelado das palas e a soldadura da base para o xerador de turbina === <br />
<br />
4.1 Fabricación das láminas O coitelo é útil para anacos máis grosos de madeira e para cortar nun oco. Pode facer un bo traballo suave da raíz da lámina, mentres que o avión funcionará mellor onde necesitas un acabado moi recto. '''Marcando as estacións''' Coloque a folla co seu mellor bordo cara a vostede na súa superficie superior. Isto en realidade convértese na parte traseira ou "abaixo" da lámina acabada. (A maior parte do lado dianteiro ou de barlovento debe ser cortado, polo que hai defectos neste lado inferior non son importantes.) A raíz da folla estará á túa dereita, a punta á esquerda, a 1000 mm da raíz (preto do extremo esquerdo). Mide dende a raíz e marca catro estacións. Estación A a 75 mm Estación B a 150 mm Estación C a 500 mm A punta a 1000 mm. En cada estación debuxa unha liña ao redor da peza usando un cadrado. <br />
<br />
[[File:01tur.jpeg|400px]]<br />
<br />
<br />
'''Afilando a folla''' O ancho da folla diminúe desde o tamaño completo na estación C ata 55 mm de ancho na estación punta. Marque o ancho da punta de 55 mm, medindo dende o lado do bordo de ataque. Debuxa unha liña aínda que a túa marca ao lado do bordo posterior na estación C e corta unha peza triangular así como para conseguir a forma cónica correcta para a folla. Calquera nós no triangular o corte non importa xa que esta peza é descartada. Tenta facer este corte "cadrado", perpendicular á superficie posterior da lámina. Podes facelo cunha serra circular ou cortando e afeitando transversalmente como se describe arriba.<br />
<br />
[[File:02tur.jpeg|400px]] <br />
<br />
'''Marcando os bordos de entrada e de saída''' O seguinte paso é cortar a cara de barlovento da lámina. Esta cara está definida polo liñas de bordo de ataque e de saída da lámina. Estas liñas deben estar marcadas con referencia á cara posterior da madeira que estivo máis arriba na anterior operación. Darlle a volta á madeira. Comeza trazando dúas liñas diagonais entre as estacións A e B na parte dianteira ou a barlovento (ver máis abaixo). Un está na cara frontal e o outro na cara o bordo de saída que agora está cara a ti. <br />
<br />
[[File:03tur.jpeg|400px]] <br />
<br />
Agora debuxa a liña do bordo de ataque como se mostra a continuación, desde a estación B, ata 16 mm (desde atrás) na estación C, e despois continúa ata a punta en 7 mm de atrás. [[File:04tur.jpeg|400px]] <br />
<br />
(Este debuxo non mostra o bit extra máis aló da punta que pode quedar na súa peza de traballo real). As medidas resúmense nesta táboa a continuación. As alturas son dende a parte traseira folla que despois descansará no banco. Elimina a madeira por encima desta altura. "Cheo" refírese ao grosor total da peza de madeira orixinal que está a usar. [[File:05tur.jpeg|400px]] '''O rastro''' A liña do bordo posterior comeza na parte inferior da liña diagonal na estación B e sobe a 5 mm en C, continuando a 5 mm ata a punta. Esta vista abaixo mostra a madeira xa eliminado entre as dúas liñas para formar a cara barlovento da pala. <br />
[[File:06tur.png|400px]] <br />
<br />
Esculpe esta cara de barlovento plana entre as dúas liñas. Coida que os bordos estean recto, seguindo as liñas. A mellor ferramenta para usar para rematar a parte exterior do a lámina é un plano, para dar un acabado suave e recto. Quizais necesites traballar no avión 45 graos coa peza de traballo, deslizando parcialmente cara aos lados, para formar a forma oca en estación C. Este paso complétase cando podes colocar unha regra pola cara entre os principais e liñas de bordo de saída e non hai "xoroba" no medio. Encha calquera chip ou pequeno ocos con recheo de madeira. Se hai algún erro grave, ou k grande non que se debilitan a folla, entón pode ter que ser descartada. Comprobe a "caída" usando un nivel como referencia. Suxeitar a madeira para que a parte da raíz sitúase nivelado e mida a diferenza de nivel entre os bordos de entrada e de saída. A diferenza ou "caída" debe ser de 11 mm no punto medio de 500 mm e de 2 mm no punta. <br />

''Pedagoxías do vento e das estrelas. As relacións sociais ás que (nunca estabamos destinados) a sobrevivir, tamén viven nos nosos corpos dolorosamente, e Audre Lorde non está aquí para lembrarnos esta lección, salvo na medida en que está presente no vento pedagóxico. Pero o vento é o noso mestre (74). -Alexis Pauline Gumbs'' do libro Mapping Queer Space(s) of Praxis and Pedagogy Editores: Elizabeth McNeil, James E. Wermers, Joshua O. Lunn'' <br />
<br />
<br />
Temos o pracer de comunicarvos que do 16 ao 29 de outubro Pin Biotranslab, Casa do Río e The Foundry establece unha colaboración para levar a cabo o evento Eco (i) Logic Queer Energy harvesting. O proxecto é posible grazas ao apoio de GOSH, unha rede para desenvolver e difundir proxectos baseados en hardware de código aberto para a ciencia. '''Eco (i) Logic Queer Recollida de enerxía''' O evento ten como obxectivo abordar a falta de mulleres, queer, trans e diversidade nos ámbitos tecnolóxicos en xeral e do hacking máis concretamente. Pero aínda máis, pretende crear unha comunidade que avalía criticamente as narrativas hexemónicas arredor das tecnoloxías, os aspectos de modernidade dos seus supostos occidentais subliñados e as súas inflexións capitalistas inherentes, entre outros. O obxectivo principal do evento é desenvolver kits que se centren na interacción co medio natural no ámbito da enerxía.. o obxectivo principal pasa pola captación de enerxía do medio natural, a través dos aeroxeradores. Estes kits de enerxía serán escalables e poderán utilizarse tanto como material pedagóxico como para instalar centrais eléctricas específicas do sitio en diferentes sitios tamén. Este traballo ten un compoñente contrainfraestrutural: unha posible consecuencia sería capacitar ás persoas para xerar a súa propia enerxía en lugar de depender de grandes empresas e moitas veces extractivas. <br />
<br />
== Introdución e valores do proceso == <br />
<br />
Aquí comeza a documentación do longo proceso de creación de prototipos do modelo Hugh Piggott The Piggott Turbine - Wind Empowerment dunha turbina eólica de código aberto. Estivemos cambiando un pouco os obxectivos do evento, pasando de desenvolver pequenos kits para ir a construír o aeroxerador de 2 m de tamaño real para proporcionar enerxía ás áreas rexionais rurais nas que estabamos traballando. Nese evento concreto estivemos traballando en The Foundry un bonito proxecto e asociación que instalamos no norte de GaliZA ao noroeste de España. Durante o evento activáronse moitas cousas entre os realizadores e os visitantes; En xeral foi unha experiencia marabillosa chea de cousas novas que estudar, aprender, facer e comprender xuntos. Escollemos este modelo porque estaba cheo de capas de interese nos niveis de aprendizaxe, comprensión e elaboración, aquí algúns niveis mesturados con capas: en primeiro lugar é un dos que é '''de código aberto''' ou polo menos ten a opción de acceder á documentación completa. realmente '''ricos a nivel pedagóxico''', realmente estivemos aprendendo a través da construción completa do propio xerador, sobre moitos temas como: <br />
<br />
* electromagnetismo *matemáticas * xeometría * electrónica * AC-DC *soldadura * talla en madeira * escultura e fundición de pezas e moito máis que foi alcanzando a través do agradable proceso de ler, aprender e construír xuntos.<br />
<br />
== Glosario == <br />
* '''AC-'''Corrente alterna producida polo alternador. Todos os fíos: palabra estadounidense para varilla ou tachuelas "roscadas" ou "hiladas".<br />
* '''Interruptor de freo''' - Interruptor usado para curtocircuitar os cables do alternador para que se pare.<br />
* '''Catalizador''' - Un produto químico usado para facer sólido o conxunto de resinas de poliéster. O catalizador reacciona co "acelerador" xa presente na mestura de resina. A calor de reacción establece o poliéster.<br />
* '''Cavalier''' - Unha marca de coche. O cavalier no Reino Unido non é o mesmo que o Cavalier nos EUA, pero ambos teñen cubos de roda útiles.<br />
* '''DC - corrente continua''' cun lado positivo e outro negativo, como nos circuítos de batería.<br />
* '''Diámetro''' - A distancia dun lado a outro dun círculo. O ancho dun disco no medio.<br />
* '''Fase''' - O tempo da alternancia cíclica da tensión nun circuíto. As diferentes fases alcanzarán o pico en diferentes momentos.<br />
* '''Poliéster''' - Un tipo de resina utilizada no traballo de fibra de vidro. Tamén apto para facer fundicións.<br />
* '''Potencia''' - a taxa de entrega de enerxía<br />
* '''Rectifier''' - Un dispositivo semicondutor que converte AC en DC para cargar a batería.<br />
* '''Raíz''' - A parte máis ancha da lámina preto do cubo no centro do rotor.<br />
* '''Rotor''' - Unha parte xiratoria. Os rotores de imáns son os discos de aceiro que transportan os imáns máis alá do estator. As palas do rotor son a "hélice" impulsado polo vento e impulsando os rotores magnéticos.<br />
* '''Soldadura''': un método para facer conexións eléctricas entre fíos usando un 'ferro' quente e recubrindo todo con soldadura fundida.<br />
* '''Arrastre''' - Forza que exerce o vento sobre un obxecto. O arrastre é paralelo á dirección do vento no obxecto. (ver Ascensor)<br />
* '''Estator''' - Un conxunto de bobinas incrustadas nunha lousa de resina para formar parte do alternador. Os imáns inducen unha tensión nas bobinas e podemos utilizala para cargar unha batería. * '''Gota''': úsase aquí para describir unha determinada medida da forma da lámina dun muíño de vento. A "caída" afecta o ángulo de a lámina ao vento. Monómero de estireno - Un disolvente con cheiro desagradable na mestura de resina de poliéster.<br />
* '''Flux''' - As 'cousas' do magnetismo. Semellante á "corrente" na electricidade. Pódese visualizar como "liñas" que saen dun polo e volvendo ao outro.<br />
* '''Furling''' - Unha acción protectora que reduce a exposición a ventos violentos ao enfrontar as aspas lonxe delas.<br />
* '''Jig''' - Un dispositivo usado para manter os imáns no seu lugar antes de colocalos na resina.<br />
* '''Borde de ataque''' - O bordo dunha lámina que golpearía un obxecto colocado no seu camiño cando o rotor xira.<br />
* '''Elevación''' - Forza que exerce o vento sobre un obxecto. A sustentación está en ángulo recto coa dirección do vento no obxecto. (ver Arrastre)<br />
* '''Molde''' - Un recipiente con forma no que se forman fundicións de resina. O molde pódese descartar despois de que a fundición se fixera.<br />
* '''Multímetro''' - Un instrumento de proba eléctrico versátil, usado para medir tensión, corrente e outros parámetros.<br />
* '''Neodimio''' - O nome dado a un tipo de imán permanente que contén neodimio, ferro e boro. Estes imáns son moi fortes e cada vez máis barato.<br />
* '''Offset''' - Unha posición excéntrica, descentrada.<br />
* '''Po de talco'''- Un recheo en po barato que se usa para espesar a resina e retardar a súa reacción (evitar que se sobrequente).<br />
* '''Cola''': unha veleta que se sobresae montada nunha pluma na parte traseira do muíño de vento que se usa para dirixila ou fóra do vento automaticamente.<br />
* '''Tap''' - unha ferramenta para facer rosca dentro dos buratos para poder colocar un parafuso no burato.<br />
* '''Empuxe''' - A forza do vento que empurra a máquina cara atrás.<br />
* '''Torre''' - O mastro que soporta o muíño de vento.<br />
* '''Bordo posterior''': o bordo da lámina máis afastado do bordo de ataque. O bordo de saída está afiado, para liberar o paso aire sen turbulencias.<br />
* '''Cuñas''': pezas cónicas de madeira que se usan para aumentar o grosor da lámina e aumentar o seu ángulo co vento preto da raíz.<br />
* '''Peza de traballo''' - A peza de madeira ou metal que se está a dar forma no taller.<br />
* '''Colamento de guiñada''': o xiro da parte superior da torre na que está montado o muíño de vento. O rodamento de guiñada permite que o muíño se enfronte ao vento.<br />

<br />
=== A fundición === <br />
<br />
A Fundición é unha organización sen ánimo de lucro con sede nunha aldea GaliZA anteriormente abandonada. Funciona tanto como residencia como como espazo de proxecto. Subscríbese aos ideais de autoorganización e ten os seguintes tres obxectivos: <br />
1. Organizar actividades no ámbito das artes, as ciencias e as humanidades fóra das institucións tradicionais, centradas no discurso crítico.<br />
2. Promover o intercambio de ideas e a colaboración intelectual fóra das limitacións impostas polo Estado e o mercado.<br />
3. Aumentar a autosuficiencia, a sustentabilidade e a concienciación co medio ambiente utilizando a tecnoloxía axeitada e o código aberto como principais recursos. Tendo en conta este contexto, o noso obxectivo é reforzar a capacidade de xerar redes que flúen do contexto rural ao urbano apoiando os intercambios non xerarquizados e democráticos de coñecementos e prácticas que permitan modelos novos e sostibles no contexto rural. Segundo iso consideramos que o novo creativo transdisciplinar dos sectores nos que estamos enredados poden ter un impacto enorme e positivo na creación deste novo paradigma.<br />
https://bravosfoundry.com/ <br />
Ademais, hai un foco temático na transdisciplinariedade, o transfeminismo e o poshumanismo. Aínda que este enfoque non é axeitadamente comprendido por categorías políticas identitarias como a raza ou o xénero, esperamos que leve á subversión das estruturas hexemónicas inscritas nos binarismos que sosteñen moitas destas categorías. O noso interese reside no desenvolvemento de ferramentas e tecnoloxías que subvertan as estruturas contemporáneas de dominación, explotación e marxinación, non nas que a reproducen. Buscamos desenvolver un entorno máis sostible abrindo as nosas prácticas baseadas nun marco de cultura libre, xerando redes e interese ao seu redor, posibilitando un fluxo de intercambio de innovación entre sectores creativos centrados na revalorización dos contextos rurais e do seu patrimonio de coñecemento. <br />

'''Alternador''' Cada rotor magnético é un disco de aceiro con 12 imáns colocados sobre el e colocados en resina. Os imáns son cada un de 50 x 50 x 20 mm, e só caben no disco. A idea é conseguir a máxima cantidade de fluxo nun espazo determinado. A turbina funciona a 650 rpm para unha saída de 400 W, polo que a forza centrífuga sobre os imáns é 60 veces a forza da gravidade. Para evitar que saian voando, hai que reforzar a fundición de resina. Un cable de aceiro inoxidable colócase arredor da parte exterior dos imáns para manter a fundición xunta a altas revolucións por minuto. Usamos inoxidable porque non é magnético, ou polo menos menos magnético que un cable de aceiro normal. Enrolarás as bobinas que producen a potencia de saída e fundirase en resina para formar un estator entre os dous rotores magnéticos. <br />

=== Sección 3, implica a creación da parte do rotor do xerador: === <br />
<br />
Paso - Xerador, rotor: Preparación do disco metálico. fíxose a máquina na tenda [[File:prod05.jpg|200px]] <br />
Paso - Xerador, rotor: Preparación do cubo da roda. <br />
[[File:frame10.jpg|200px]] '''O cubo da roda''' Podes atopar un cubo de roda traseira de coche usado (Golf, Toyota, etc.) que teña un xeito sinxelo engade o eixe ou, alternativamente, compre un cubos de remolque en liña novos a baixo custo. PCD ou "diámetro do círculo de paso" é o diámetro do círculo do patrón do burato no cubo, e normalmente este será de 100 mm para un cubo de roda de coche, ou de 4 polgadas para un cubo de remolque. Os hubs dos coches poden ter un tambor de freo que non precisa. Isto pódese eliminar usando a disco de corte nunha moedora. O enfoque máis sinxelo é facer catro cortes rectos ao redor os catro orificios na parte frontal, deixando unha superficie cadrada na que se monta o imán rotores. Estas fotos mostran un cubo de roda traseira de golf: primeiro se corta o tambor de freo e a continuación, o cubo acabado despois de cortar o tambor. Un típico cubo de coche de roda traseira con a brida no extremo traseiro do eixe do tronco que se pode reutilizar para montalo. Os cubos de remolque, por outra banda, son de calidade bastante básica, e os rodamentos tamén poden ser barato para uso a longo prazo, pero son artigos facilmente dispoñibles que se poden mercar en liña como novo. Os debuxos que aparecen a continuación (de autow.com) mostran un concentrador e un stub típicos eixe que se compran por separado. Debe estar preparado para substituír os rodamentos por unha marca nomeada (como SKF). É fácil de substituír os conos e rolos internos, pero hai que golpear as capas exteriores suavemente fóra do cubo cunha deriva adecuada. Mantéñaos rectos tocando uniformemente lados opostos e teña coidado de non raiar o asento. Paso - Xerador, rotor: Preparación da plantilla. <br />

<br />
4.1 Fabricación das láminas O coitelo é útil para anacos máis grosos de madeira e para cortar nun oco. Pode facer un bo traballo suave da raíz da lámina, mentres que o avión funcionará mellor onde necesitas un acabado moi recto. '''Marcando as estacións''' Coloque a folla co seu mellor bordo cara a vostede na súa superficie superior. Isto en realidade convértese na parte traseira ou "abaixo" da lámina acabada. (A maior parte do lado dianteiro ou de barlovento debe ser cortado, polo que hai defectos neste lado inferior non son importantes.) A raíz da folla estará á túa dereita, a punta á esquerda, a 1000 mm da raíz (preto do extremo esquerdo). Mide dende a raíz e marca catro estacións. Estación A a 75 mm Estación B a 150 mm Estación C a 500 mm A punta a 1000 mm. En cada estación debuxa unha liña ao redor da peza usando un cadrado. <br />
<br />
[[File:01tur.jpeg|400px]] <br />
<br />
<br />
'''Afilando a folla''' O ancho da folla diminúe desde o tamaño completo na estación C ata 55 mm de ancho na estación punta. Marque o ancho da punta de 55 mm, medindo dende o lado do bordo de ataque. Debuxa unha liña aínda que a túa marca ao lado do bordo posterior na estación C e corta unha peza triangular así como para conseguir a forma cónica correcta para a folla. Calquera nós no triangular o corte non importa xa que esta peza é descartada. Tenta facer este corte "cadrado", perpendicular á superficie posterior da lámina. Podes facelo cunha serra circular ou cortando e afeitando transversalmente como se describe arriba.<br />
<br />
[[File:02tur.jpeg|400px]] <br />
<br />
'''Marcando os bordos de entrada e de saída''' O seguinte paso é cortar a cara de barlovento da lámina. Esta cara está definida polo liñas de bordo de ataque e de saída da lámina. Estas liñas deben estar marcadas con referencia á cara posterior da madeira que estivo máis arriba na anterior operación. Darlle a volta á madeira. Comeza trazando dúas liñas diagonais entre as estacións A e B na parte dianteira ou a barlovento (ver máis abaixo). Un está na cara frontal e o outro na cara o bordo de saída que agora está cara a ti. <br />
<br />
[[File:03tur.jpeg|400px]] <br />
<br />
Agora debuxa a liña do bordo de ataque como se mostra a continuación, desde a estación B, ata 16 mm (desde atrás) na estación C, e despois continúa ata a punta en 7 mm de atrás. [[File:04tur.jpeg|400px]] <br />
<br />
(Este debuxo non mostra o bit extra máis aló da punta que pode quedar na súa peza de traballo real). As medidas resúmense nesta táboa a continuación. As alturas son dende a parte traseira folla que despois descansará no banco. Elimina a madeira por encima desta altura. "Cheo" refírese ao grosor total da peza de madeira orixinal que está a usar. [[File:05tur.jpeg|400px]] '''O rastro''' A liña do bordo posterior comeza na parte inferior da liña diagonal na estación B e sobe a 5 mm en C, continuando a 5 mm ata a punta. Esta vista abaixo mostra a madeira xa eliminado entre as dúas liñas para formar a cara barlovento da pala. <br />
[[File:06tur.png|400px]] <br />
<br />
Esculpe esta cara de barlovento plana entre as dúas liñas. Coida que os bordos estean recto, seguindo as liñas. A mellor ferramenta para usar para rematar a parte exterior do a lámina é un plano, para dar un acabado suave e recto. Quizais necesites traballar no avión 45 graos coa peza de traballo, deslizando parcialmente cara aos lados, para formar a forma oca en estación C. Este paso complétase cando podes colocar unha regra pola cara entre os principais e liñas de bordo de saída e non hai "xoroba" no medio. Encha calquera chip ou pequeno ocos con recheo de madeira. Se hai algún erro grave, ou k grande non que se debilitan a folla, entón pode ter que ser descartada. Comprobe a "caída" usando un nivel como referencia. Suxeitar a madeira para que a parte da raíz sitúase nivelado e mida a diferenza de nivel entre os bordos de entrada e de saída. A diferenza ou "caída" debe ser de 11 mm no punto medio de 500 mm e de 2 mm no punta. <br />

''Pedagogies of the Wind and Stars. The social relations that we (were never meant to) survive, also live in our bodies painfully, and Audre Lorde is not here to remind us of this lesson herself, except in as much that she is present in the pedagogical wind. But wind is our teacher (74). -Alexis Pauline Gumbs'' from the book Mapping Queer Space(s) of Praxis and Pedagogy <br />
Editors: Elizabeth McNeil, James E. Wermers, Joshua O. Lunn'' <br />
<br />
We have the pleasure to communicate you that from 16 to 29 of October Pin Biotranslab, Casa do Río e The Foundry establishes a collaboration to run the event Eco (i) Logic Queer Energy harvesting. The project is possible thanks to the support of GOSH, an network for develop and disseminate projects based on Open Source hardware for Science.<br />
<br />
'''Eco (i) Logic Queer Energy harvesting''' <br />
The event aims at addressing the lack of women, queer, trans and diversity in technological fields in general and hacking more specifically. But even more so, it aims at creating a community that critically assesses the hegemonic narratives around technologies, the modernity aspects of its underlining Western assumptions and its inherent capitalist inflections, among others.<br />
The main purpose of the event is to develop kits that focus on interacting with the natural environment on the field of energy.. the main objective lies on harvesting energy of the natural environment, through wind turbines. These power kits will be scalable and can be used both as pedagogical material and to set up site-specific power plants in different sites as well. There is a counter-infrastructural component to this work: one possible consequence would be to empower people to generate their own energy instead of relying on large and often extractive companies.<br />
<br />
== Introduction and values of the process ==<br />
<br />
Here starts the documentation of the long process of the prototyping the Hugh Piggott The Piggott Turbine – Wind Empowerment model of an Open source wind turbine. We were changing a bit the goals of the event from developing small kits to going to build the real 2m size wind turbine to provide energy to the rural regional areas we were working on. In that specific event we were working at The Foundry a nice project and association that we have settled on the north part of GaliZA into the Northwest of Spain.<br />
<br />
During the event many things have been activated between the doers and the visitors; In general It was a wondering experience full of new things to study, learn, doing and understand together. <br />
<br />
We chose this model because It was full of layers of interest on the levels of learning, understanding and making it, here some levels mixed up with layers: <br />
<br />
first to all is one of the ones that is '''open source''' or at least has the option to access the full documentation.<br />
<br />
really '''rich on the pedagogical level''', we were really learning through the complete building of the generator itself, about many topics as :<br />
* electromagnetism<br />
* mathematics<br />
* geometry<br />
* electronics<br />
* AC-DC<br />
* welding<br />
* wood carving<br />
* sculpting and casting pieces<br />
and much more that was reaching through the nice process of reading, learning and building together.<br />
<br />
== Glossary ==<br />
<br />
* '''AC-'''Alternating current as produced by the alternator. All thread - USA word for 'threaded' or 'spun' rod or studding<br />
* '''Brake switch''' - A switch used to short-circuit the wires from the alternator so that it stops.<br />
* '''Catalyst''' - A chemical used to make the polyester resin set solid. Catalyst reacts with 'accelerator' already present in the resin mix. <br />
The heat of reaction sets the polyester.<br />
* '''Cavalier''' - A make of car. The cavalier in the UK is not the same as the Cavalier in the USA but both have useful wheel hubs.<br />
* '''DC - direct current''' with a positive and a negative side, as in battery circuits.<br />
* '''Diameter''' - The distance from one side of a circle to another. The width of a disk right across the middle.<br />
* '''Phase''' - The timing of the cyclical alternation of voltage in a circuit. Different phases will peak at different times.<br />
* '''Polyester''' - A type of resin used in fibreglass work. Also suitable for making castings.<br />
* '''Power''' - the rate of delivery of energy<br />
* '''Rectifier''' - A semiconductor device that turns AC into DC for charging the battery.<br />
* '''Root''' - The widest part of the blade near to the hub at the center of the rotor.<br />
* '''Rotor''' - A rotating part. Magnet rotors are the steel diskscarrying the magnets past the stator. Rotor blades are the 'propeller' <br />
driven by the wind and driving the magnet rotors.<br />
* '''Soldering''' - A method for making electrical connections between wires using a hot 'iron' and coating everything with molten solder.<br />
* '''Drag''' - A force exerted by the wind on an object. Drag is parallel to the wind direction at the object. (see Lift) <br />
* '''Stator''' - An assembly of coils embedded in a slab of resin to form part of the alternator. The magnets induce a voltage in the coils and we can use this to charge a battery.<br />
* '''Drop''' - Used here to describe a certain measurement of the shape of a windmill blade. The 'drop' affects the angle of<br />
the blade to the wind. Styrene monomer - A nasty smelling solvent in the polyester resin mix.<br />
* '''Flux''' - The 'stuff' of magnetism. Similar to 'current' in electricity. It can be visualized as 'lines' coming out of one pole and <br />
returning to the other.<br />
* '''Furling''' - A protective action that reduces exposure to violent winds by facing the blades away from them.<br />
* '''Jig''' - A device used to hold the magnets in place before setting them in resin.<br />
* '''Leading edge''' - The edge of a blade that would strike an object placed in its path as the rotor spins.<br />
* '''Lift''' - A force exerted by the wind on an object. Lift is at right angles to the wind direction at the object. (see Drag)<br />
* '''Mold''' - A shaped container in which resin castings are formed. The mould can be discarded after the casting has set.<br />
* '''Multimeter''' - A versatile electrical test instrument, used to measure voltage, current and other parameters.<br />
* '''Neodymium''' - The name given to a type of permanent magnet containing neodymium, iron and boron. These magnets are very strong and <br />
getting cheaper all the time.<br />
* '''Offset''' - An eccentric position, off centre.<br />
* '''Talcum powder'''- A cheap filler powder used to thicken the resin and slow its reaction (prevent it overheating).<br />
* '''Tail''' - A projecting vane mounted on a boom at the back ofthe windmill used to steer it into or out of the wind automatically.<br />
* '''Tap''' - a tool for making thread inside holes so you can fit a screw into the hole.<br />
* '''Thrust''' - The force of the wind pushing the machine backwards.<br />
* '''Tower''' - The mast supporting the windmill.<br />
* '''Trailing edge''' - The blade edge furthest from the leading edge. The trailing edge is sharpened, so as to release the passing <br />
air without turbulence.<br />
* '''Wedges''' - Tapered pieces of wood used to build up the blade thickness and increase its angle to the wind near the root.<br />
* '''Work-piece''' - The piece of wood or metal being shaped in the workshop.<br />
* '''Yaw bearing''' - the swivel at the top of the tower on which the windmill is mounted. The yaw bearing allows the windmill to face the wind.<br />

<br />
=== The Foundry ===<br />
The Foundry is a non-profit organization based in a previously abandoned GaliZA village. It functions both as a residency and as a project space. It subscribes to the ideals of self-organization, and has the following three objectives:<br />
1. Organizing activities in the field of the arts, science and humanities outside of traditional institutions, focusing on critical discourse.<br />
2. Promoting the exchange of ideas and intellectual collaboration outside of the constraints imposed by state and market.<br />
3. Increasing self-sufficiency, sustainability, and an awareness of the environment using appropriate technology and open source as main resources.<br />
Taking into account this context, our aim is to reinforce the capacity to generate networks flowing from rural to urban context supporting non hierarchy and democratic exchanges of knowledge and practices that can enable new and sustainable models within rural contexts. According to that we consider that the new trans-disciplinary creative sectors in which we are entangled can have a huge and positive impact in the creation of this new paradigm. https://bravosfoundry.com/<br />
Aside from that, there is thematic focus on transdisciplinarity, transfeminism and post-humanism. While this focus is not adequately grasped by identity-political categories like race or gender, we hope it leads to the subversion of hegemonic structures inscribed in the binarisms upholding many of these categories. Our interest lies in the development of tools and technologies that subvert contemporary structures of domination, exploitation and marginalization, not in those that reproduce it.<br />
We seek to develop a more sustainable environment by opening up our practices based on a free culture framework, generating networks and interest around them, enabling a flow of exchange of innovation across creative sectors focusing on revaluation of rural contexts and its knowledge heritage.<br />

=== '''Section 2, involves the construction of '''the alternator''' parts using the devices from the section 1.''' ===<br />
<br />
'''Alternator'''<br />
Each magnet rotor is a steel disk with 12 magnets placed on it and set in resin. The magnets are each 50 x 50 x 20 mm, and they only just fit on the disk. The idea is to achieve the maximum amount of flux in a given space.<br />
The turbine runs at 650 rpm for 400W output, so the centrifugal force on the magnets is 60 times the force of gravity. To prevent them flying off, the resin casting needs to be reinforced. Stainless steel wire rope is placed around the outside of the magnets to hold the casting together at high rpm. We use stainless because it is non-magnetic, or at least less magnetic than normal steel wire rope. <br />
<br />
You will wind the coils that produce the output power and cast them in resin to form a stator between the two magnet rotors. Photos of the final pieces here <br />

<br />
'''The wheel hub'''<br />
<br />
You can find a used car rear wheel hub (Golf, Toyota, etc.) that has a simple way to<br />
attach the axle, or alternatively buy a trailer hubs online new at low cost.<br />
PCD or ‘pitch circle diameter' is the diameter of the circle of the hole pattern in the<br />
hub, and usually this will be 100mm for a car wheel hub, or 4 inches for a trailer hub.<br />
Car hubs may have a brake-drum that you do not need. This can be removed using a<br />
cutting disk on a grinder. The simplest approach is to make four straight cuts around<br />
the four holes in the front, leaving a square surface to which you mount the magnet<br />
rotors. These photos show a golf rear wheel hub – first the brake-drum being cut, and<br />
then the finished hub after cutting off the drum.A typical rear wheel car hub with a <br />
flange on the back end of the stub shaft that can reused to mount it.<br />
Trailer hubs on the other hand are rather basic quality, and the bearings may be too<br />
cheap for long term use, but they are readily available items that can be purchased<br />
online as new. The drawings below (from autow.com) show a typical hub and stub<br />
axle which are bought separately.<br />
You need to be ready to replace the bearings with a named brand (such as SKF). It’s<br />
easy to replace the inner cones and rollers but the outer shells need to be knocked<br />
gently out of the hub with a suitable drift. Keep them straight by tapping evenly on<br />
opposite sides, and take care not to scratch the seating.<br />

Step - Generator, rotor: PreStep<br />
<br />
=== Section 4, involves the craving of the blades and the welding of the base for the turbine generator. ===<br />
<br />
4.1 Making the blades <br />
The drawknife is useful for thicker chunks of wood, and for cutting down into a hollow. <br />
It can make a nice smooth job of the root of the blade, whereas the plane will work better <br />
where you need a very straight finish.<br />
<br />
'''Marking the stations.'''<br />
<br />
Place the blade with its best edge toward you on its upper surface. This will actually<br />
become the back or ‘downwind’ side of the finished blade.<br />
(Most of the front or windward side is to be cut off, so defects on this underneath side<br />
are not important.)<br />
<br />
The root of the blade will be on your right, the tip at the left, 1000 mm from the root<br />
(near the left end).<br />
<br />
Measure from the root, and mark four stations.<br />
Station A at 75mm<br />
Station B at 150 mm<br />
Station C at 500 mm<br />
The Tip at 1000 mm.<br />
<br />
<br />
At each station draw a line right around the workpiece using a square.<br />
<br />
[[File:01tur.jpeg|400px]]<br />
<br />
<br />
'''Tapering the blade'''<br />
The width of the blade tapers down from full size at station C to 55 mm wide at the<br />
tip. Mark the 55 mm tip width, measuring from the leading edge side. Draw a line<br />
though your mark to the trailing edge side at C station and cut off a triangular piece so<br />
as to achieve the correct tapered shape for the blade. Any knots in the triangular<br />
off cut do not matter as this piece is discarded. Try to make this a "square" cut,<br />
perpendicular to the back surface of the blade.<br />
You can do this with a circular saw, or by cross-cutting and shaving as described<br />
above.<br />
<br />
<br />
[[File:02tur.jpeg|400px]]<br />
<br />
'''Marking the leading and trailing edges'''<br />
The next step is to cut the windward face of the blade. This face is defined by the<br />
leading and trailing edge lines of the blade. These lines need to be marked with<br />
reference to the back face of the wood which has been uppermost in the previous<br />
operation.<br />
<br />
Turn the wood over. Start by drawing two diagonal lines between stations A and B<br />
on the front or windward side (see below). One is on the front face and the other on<br />
the trailing edge which is now toward you. <br />
<br />
[[File:03tur.jpeg|400px]]<br />
<br />
<br />
Now draw the leading edge line as shown below, <br />
from station B, down to 16mm(from the back) at station C, then continuing to the tip at<br />
7mm from the back.<br />
<br />
[[File:04tur.jpeg|400px]]<br />
<br />
<br />
(This drawing does not show the extra bit beyond the tip which may remain <br />
in your actual workpiece.)<br />
<br />
Measurements are summarised in this table below. Heights are from the back of the<br />
blade which will then rest on the bench. Remove the wood above this height. "Full"<br />
refers to the full thickness of the original piece of wood you are using.<br />
<br />
<br />
<br />
[[File:05tur.jpeg|400px]]<br />
<br />
<br />
'''The trailing''' <br />
The trailing edge line starts at the bottom of the diagonal line at station B, and <br />
rises to 5mm at C, continuing at 5 mm to the tip. This view below shows the wood <br />
already removed between the two lines to form the windward face of the blade.<br />
<br />
<br />
[[File:06tur.png|400px]]<br />
<br />
<br />
Carve this flat windward face between the 2 lines. Take care that the edges are<br />
straight, following the lines. The best tool to use for finishing the outer part of the<br />
blade is a plane, to give a smooth, straight finish. You may need to work the plane at<br />
45 degrees to the workpiece, sliding partly sideways, to form the hollow shape at<br />
station C.<br />
<br />
This step is completed when you can place a ruler across the face between the leading<br />
and trailing edge lines and there is no ‘hump’ in the middle. Fill any chips or small<br />
hollows with wood filler. If there are any serious errors, or large knots that weaken<br />
the blade then it may have to be discarded.<br />
Check the “drop” using a level as a reference. Clamp the wood so that the root part<br />
sits level, and measure the difference in level between the leading and trailing edges.<br />
The difference or “drop” should be 11 mm at the 500 mm mid-point, and 2 mm at the<br />
tip.<br />

''Pedagoxías do vento e das estrelas. As relacións sociais ás que (nunca estabamos destinados) a sobrevivir, tamén viven nos nosos corpos dolorosamente, e Audre Lorde non está aquí para lembrarnos esta lección, salvo na medida en que está presente no vento pedagóxico. Pero o vento é o noso mestre (74). -Alexis Pauline Gumbs'' do libro Mapping Queer Space(s) of Praxis and Pedagogy Editores: Elizabeth McNeil, James E. Wermers, Joshua O. Lunn'' <br />
<br />
<br />
Temos o pracer de comunicarvos que do 16 ao 29 de outubro Pin Biotranslab, Casa do Río e The Foundry establece unha colaboración para levar a cabo o evento Eco (i) Logic Queer Energy harvesting. O proxecto é posible grazas ao apoio de GOSH, unha rede para desenvolver e difundir proxectos baseados en hardware de código aberto para a ciencia. '''Eco (i) Logic Queer Recollida de enerxía''' O evento ten como obxectivo abordar a falta de mulleres, queer, trans e diversidade nos ámbitos tecnolóxicos en xeral e do hacking máis concretamente. Pero aínda máis, pretende crear unha comunidade que avalía criticamente as narrativas hexemónicas arredor das tecnoloxías, os aspectos de modernidade dos seus supostos occidentais subliñados e as súas inflexións capitalistas inherentes, entre outros. O obxectivo principal do evento é desenvolver kits que se centren na interacción co medio natural no ámbito da enerxía.. o obxectivo principal pasa pola captación de enerxía do medio natural, a través dos aeroxeradores. Estes kits de enerxía serán escalables e poderán utilizarse tanto como material pedagóxico como para instalar centrais eléctricas específicas do sitio en diferentes sitios tamén. Este traballo ten un compoñente contrainfraestrutural: unha posible consecuencia sería capacitar ás persoas para xerar a súa propia enerxía en lugar de depender de grandes empresas e moitas veces extractivas. <br />
<br />
== Introdución e valores do proceso == <br />
<br />
Aquí comeza a documentación do longo proceso de creación de prototipos do modelo Hugh Piggott The Piggott Turbine - Wind Empowerment dunha turbina eólica de código aberto. Estivemos cambiando un pouco os obxectivos do evento, pasando de desenvolver pequenos kits para ir a construír o aeroxerador de 2 m de tamaño real para proporcionar enerxía ás áreas rexionais rurais nas que estabamos traballando. Nese evento concreto estivemos traballando en The Foundry un bonito proxecto e asociación que instalamos no norte de GaliZA ao noroeste de España. Durante o evento activáronse moitas cousas entre os realizadores e os visitantes; En xeral foi unha experiencia marabillosa chea de cousas novas que estudar, aprender, facer e comprender xuntos. Escollemos este modelo porque estaba cheo de capas de interese nos niveis de aprendizaxe, comprensión e elaboración, aquí algúns niveis mesturados con capas: en primeiro lugar é un dos que é '''de código aberto''' ou polo menos ten a opción de acceder á documentación completa. realmente '''ricos a nivel pedagóxico''', realmente estivemos aprendendo a través da construción completa do propio xerador, sobre moitos temas como: <br />
<br />
* electromagnetismo *matemáticas * xeometría * electrónica * AC-DC *soldadura * talla en madeira * escultura e fundición de pezas e moito máis que foi alcanzando a través do agradable proceso de ler, aprender e construír xuntos.<br />

<br />
=== A fundición === <br />
<br />
A Fundición é unha organización sen ánimo de lucro con sede nunha aldea GaliZA anteriormente abandonada. Funciona tanto como residencia como como espazo de proxecto. Subscríbese aos ideais de autoorganización e ten os seguintes tres obxectivos: <br />
1. Organizar actividades no ámbito das artes, as ciencias e as humanidades fóra das institucións tradicionais, centradas no discurso crítico.<br />
2. Promover o intercambio de ideas e a colaboración intelectual fóra das limitacións impostas polo Estado e o mercado.<br />
3. Aumentar a autosuficiencia, a sustentabilidade e a concienciación co medio ambiente utilizando a tecnoloxía axeitada e o código aberto como principais recursos. Tendo en conta este contexto, o noso obxectivo é reforzar a capacidade de xerar redes que flúen do contexto rural ao urbano apoiando os intercambios non xerarquizados e democráticos de coñecementos e prácticas que permitan modelos novos e sostibles no contexto rural. Segundo iso consideramos que o novo creativo transdisciplinar dos sectores nos que estamos enredados poden ter un impacto enorme e positivo na creación deste novo paradigma.<br />
https://bravosfoundry.com/ <br />
Ademais, hai un foco temático na transdisciplinariedade, o transfeminismo e o poshumanismo. Aínda que este enfoque non é axeitadamente comprendido por categorías políticas identitarias como a raza ou o xénero, esperamos que leve á subversión das estruturas hexemónicas inscritas nos binarismos que sosteñen moitas destas categorías. O noso interese reside no desenvolvemento de ferramentas e tecnoloxías que subvertan as estruturas contemporáneas de dominación, explotación e marxinación, non nas que a reproducen. Buscamos desenvolver un entorno máis sostible abrindo as nosas prácticas baseadas nun marco de cultura libre, xerando redes e interese ao seu redor, posibilitando un fluxo de intercambio de innovación entre sectores creativos centrados na revalorización dos contextos rurais e do seu patrimonio de coñecemento. <br />

=== '''Sección 2, implica a construción de pezas do '''alternador''' utilizando os dispositivos da sección 1.''' === <br />
<br />
'''Alternador''' Cada rotor magnético é un disco de aceiro con 12 imáns colocados sobre el e colocados en resina. Os imáns son cada un de 50 x 50 x 20 mm, e só caben no disco. A idea é conseguir a máxima cantidade de fluxo nun espazo determinado. A turbina funciona a 650 rpm para unha saída de 400 W, polo que a forza centrífuga sobre os imáns é 60 veces a forza da gravidade. Para evitar que saian voando, hai que reforzar a fundición de resina. Un cable de aceiro inoxidable colócase arredor da parte exterior dos imáns para manter a fundición xunta a altas revolucións por minuto. Usamos inoxidable porque non é magnético, ou polo menos menos magnético que un cable de aceiro normal. Enrolarás as bobinas que producen a potencia de saída e fundirase en resina para formar un estator entre os dous rotores magnéticos. <br />

<br />
Paso - Xerador, rotor: Preparación do disco metálico. fíxose a máquina na tenda [[File:prod05.jpg|200px]] <br />
Paso - Xerador, rotor: Preparación do cubo da roda. <br />
[[File:frame10.jpg|200px]] '''O cubo da roda''' Podes atopar un cubo de roda traseira de coche usado (Golf, Toyota, etc.) que teña un xeito sinxelo engade o eixe ou, alternativamente, compre un cubos de remolque en liña novos a baixo custo. PCD ou "diámetro do círculo de paso" é o diámetro do círculo do patrón do burato no cubo, e normalmente este será de 100 mm para un cubo de roda de coche, ou de 4 polgadas para un cubo de remolque. Os hubs dos coches poden ter un tambor de freo que non precisa. Isto pódese eliminar usando a disco de corte nunha moedora. O enfoque máis sinxelo é facer catro cortes rectos ao redor os catro orificios na parte frontal, deixando unha superficie cadrada na que se monta o imán rotores. Estas fotos mostran un cubo de roda traseira de golf: primeiro se corta o tambor de freo e a continuación, o cubo acabado despois de cortar o tambor. Un típico cubo de coche de roda traseira con a brida no extremo traseiro do eixe do tronco que se pode reutilizar para montalo. Os cubos de remolque, por outra banda, son de calidade bastante básica, e os rodamentos tamén poden ser barato para uso a longo prazo, pero son artigos facilmente dispoñibles que se poden mercar en liña como novo. Os debuxos que aparecen a continuación (de autow.com) mostran un concentrador e un stub típicos eixe que se compran por separado.

4.1 Fabricación das láminas O coitelo é útil para anacos máis grosos de madeira e para cortar nun oco. Pode facer un bo traballo suave da raíz da lámina, mentres que o avión funcionará mellor onde necesitas un acabado moi recto. '''Marcando as estacións''' Coloque a folla co seu mellor bordo cara a vostede na súa superficie superior. Isto en realidade convértese na parte traseira ou "abaixo" da lámina acabada. (A maior parte do lado dianteiro ou de barlovento debe ser cortado, polo que hai defectos neste lado inferior non son importantes.) A raíz da folla estará á túa dereita, a punta á esquerda, a 1000 mm da raíz (preto do extremo esquerdo). Mide dende a raíz e marca catro estacións. Estación A a 75 mm Estación B a 150 mm Estación C a 500 mm A punta a 1000 mm. En cada estación debuxa unha liña ao redor da peza usando un cadrado. <br />
<br />
[[File:01tur.jpeg|400px]] <br />
<br />
<br />
'''Afilando a folla''' O ancho da folla diminúe desde o tamaño completo na estación C ata 55 mm de ancho na estación punta. Marque o ancho da punta de 55 mm, medindo dende o lado do bordo de ataque. Debuxa unha liña aínda que a túa marca ao lado do bordo posterior na estación C e corta unha peza triangular así como para conseguir a forma cónica correcta para a folla. Calquera nós no triangular o corte non importa xa que esta peza é descartada. Tenta facer este corte "cadrado", perpendicular á superficie posterior da lámina. Podes facelo cunha serra circular ou cortando e afeitando transversalmente como se describe arriba.<br />
<br />
[[File:02tur.jpeg|400px]] '''Marcando os bordos de entrada e de saída''' O seguinte paso é cortar a cara de barlovento da lámina. Esta cara está definida polo liñas de bordo de ataque e de saída da lámina. Estas liñas deben estar marcadas con referencia á cara posterior da madeira que estivo máis arriba na anterior operación. Darlle a volta á madeira. Comeza trazando dúas liñas diagonais entre as estacións A e B na parte dianteira ou a barlovento (ver máis abaixo). Un está na cara frontal e o outro na cara o bordo de saída que agora está cara a ti. <br />
[[File:03tur.jpeg|400px]] <br />
<br />
Agora debuxa a liña do bordo de ataque como se mostra a continuación, desde a estación B, ata 16 mm (desde atrás) na estación C, e despois continúa ata a punta en 7 mm de atrás. [[Ficheiro:04tur.jpeg|400px]] (Este debuxo non mostra o bit extra máis aló da punta que pode quedar na súa peza de traballo real). As medidas resúmense nesta táboa a continuación. As alturas son dende a parte traseira folla que despois descansará no banco. Elimina a madeira por encima desta altura. "Cheo" refírese ao grosor total da peza de madeira orixinal que está a usar. [[File:05tur.jpeg|400px]] '''O rastro''' A liña do bordo posterior comeza na parte inferior da liña diagonal na estación B e sobe a 5 mm en C, continuando a 5 mm ata a punta. Esta vista abaixo mostra a madeira xa eliminado entre as dúas liñas para formar a cara barlovento da pala. [[File:06tur.png|400px]] <br />
<br />
Esculpe esta cara de barlovento plana entre as dúas liñas. Coida que os bordos estean recto, seguindo as liñas. A mellor ferramenta para usar para rematar a parte exterior do a lámina é un plano, para dar un acabado suave e recto. Quizais necesites traballar no avión 45 graos coa peza de traballo, deslizando parcialmente cara aos lados, para formar a forma oca en estación C. Este paso complétase cando podes colocar unha regra pola cara entre os principais e liñas de bordo de saída e non hai "xoroba" no medio. Encha calquera chip ou pequeno ocos con recheo de madeira. Se hai algún erro grave, ou k grande non que se debilitan a folla, entón pode ter que ser descartada. Comprobe a "caída" usando un nivel como referencia. Suxeitar a madeira para que a parte da raíz sitúase nivelado e mida a diferenza de nivel entre os bordos de entrada e de saída. A diferenza ou "caída" debe ser de 11 mm no punto medio de 500 mm e de 2 mm no punta. <gallery mode="packed-hover" heights=320px><br />

''Pedagoxías do vento e das estrelas. As relacións sociais ás que (nunca estabamos destinados) a sobrevivir, tamén viven nos nosos corpos dolorosamente, e Audre Lorde non está aquí para lembrarnos esta lección, salvo na medida en que está presente no vento pedagóxico. Pero o vento é o noso mestre (74). -Alexis Pauline Gumbs'' do libro Mapping Queer Space(s) of Praxis and Pedagogy Editores: Elizabeth McNeil, James E. Wermers, Joshua O. Lunn'' <br />
<br />
<br />
Temos o pracer de comunicarvos que do 16 ao 29 de outubro Pin Biotranslab, Casa do Río e The Foundry establece unha colaboración para levar a cabo o evento Eco (i) Logic Queer Energy harvesting. O proxecto é posible grazas ao apoio de GOSH, unha rede para desenvolver e difundir proxectos baseados en hardware de código aberto para a ciencia. '''Eco (i) Logic Queer Recollida de enerxía''' O evento ten como obxectivo abordar a falta de mulleres, queer, trans e diversidade nos ámbitos tecnolóxicos en xeral e do hacking máis concretamente. Pero aínda máis, pretende crear unha comunidade que avalía criticamente as narrativas hexemónicas arredor das tecnoloxías, os aspectos de modernidade dos seus supostos occidentais subliñados e as súas inflexións capitalistas inherentes, entre outros. O obxectivo principal do evento é desenvolver kits que se centren na interacción co medio natural no ámbito da enerxía.. o obxectivo principal pasa pola captación de enerxía do medio natural, a través dos aeroxeradores. Estes kits de enerxía serán escalables e poderán utilizarse tanto como material pedagóxico como para instalar centrais eléctricas específicas do sitio en diferentes sitios tamén. Este traballo ten un compoñente contrainfraestrutural: unha posible consecuencia sería capacitar ás persoas para xerar a súa propia enerxía en lugar de depender de grandes empresas e moitas veces extractivas. <br />
<br />
== Introdución e valores do proceso == <br />
<br />
Aquí comeza a documentación do longo proceso de creación de prototipos do modelo Hugh Piggott The Piggott Turbine - Wind Empowerment dunha turbina eólica de código aberto. Estivemos cambiando un pouco os obxectivos do evento, pasando de desenvolver pequenos kits para ir a construír o aeroxerador de 2 m de tamaño real para proporcionar enerxía ás áreas rexionais rurais nas que estabamos traballando. Nese evento concreto estivemos traballando en The Foundry un bonito proxecto e asociación que instalamos no norte de GaliZA ao noroeste de España. Durante o evento activáronse moitas cousas entre os realizadores e os visitantes; En xeral foi unha experiencia marabillosa chea de cousas novas que estudar, aprender, facer e comprender xuntos. Escollemos este modelo porque estaba cheo de capas de interese nos niveis de aprendizaxe, comprensión e elaboración, aquí algúns niveis mesturados con capas: en primeiro lugar é un dos que é '''de código aberto''' ou polo menos ten a opción de acceder á documentación completa. realmente '''ricos a nivel pedagóxico''', realmente estivemos aprendendo a través da construción completa do propio xerador, sobre moitos temas como: <br />
<br />
* electromagnetismo *matemáticas * xeometría * electrónica * AC-DC *soldadura * talla en madeira * escultura e fundición de pezas e moito máis que foi alcanzando a través do agradable proceso de ler, aprender e construír xuntos.<br />
<br />
== Glosario == <br />
* '''AC-'''Corrente alterna producida polo alternador. Todos os fíos: palabra estadounidense para varilla ou tachuelas "roscadas" ou "hiladas".<br />
* '''Interruptor de freo''' - Interruptor usado para curtocircuitar os cables do alternador para que se pare.<br />
* '''Catalizador''' - Un produto químico usado para facer sólido o conxunto de resinas de poliéster. O catalizador reacciona co "acelerador" xa presente na mestura de resina. A calor de reacción establece o poliéster.<br />
* '''Cavalier''' - Unha marca de coche. O cavalier no Reino Unido non é o mesmo que o Cavalier nos EUA, pero ambos teñen cubos de roda útiles.<br />
* '''DC - corrente continua''' cun lado positivo e outro negativo, como nos circuítos de batería.<br />
* '''Diámetro''' - A distancia dun lado a outro dun círculo. O ancho dun disco no medio.<br />
* '''Fase''' - O tempo da alternancia cíclica da tensión nun circuíto. As diferentes fases alcanzarán o pico en diferentes momentos.<br />
* '''Poliéster''' - Un tipo de resina utilizada no traballo de fibra de vidro. Tamén apto para facer fundicións.<br />
* '''Potencia''' - a taxa de entrega de enerxía<br />
* '''Rectifier''' - Un dispositivo semicondutor que converte AC en DC para cargar a batería.<br />
* '''Raíz''' - A parte máis ancha da lámina preto do cubo no centro do rotor.<br />
* '''Rotor''' - Unha parte xiratoria. Os rotores de imáns son os discos de aceiro que transportan os imáns máis alá do estator. As palas do rotor son a "hélice" impulsado polo vento e impulsando os rotores magnéticos.<br />
* '''Soldadura''': un método para facer conexións eléctricas entre fíos usando un 'ferro' quente e recubrindo todo con soldadura fundida.<br />
* '''Arrastre''' - Forza que exerce o vento sobre un obxecto. O arrastre é paralelo á dirección do vento no obxecto. (ver Ascensor)<br />
* '''Estator''' - Un conxunto de bobinas incrustadas nunha lousa de resina para formar parte do alternador. Os imáns inducen unha tensión nas bobinas e podemos utilizala para cargar unha batería. * '''Gota''': úsase aquí para describir unha determinada medida da forma da lámina dun muíño de vento. A "caída" afecta o ángulo de a lámina ao vento. Monómero de estireno - Un disolvente con cheiro desagradable na mestura de resina de poliéster.<br />
* '''Flux''' - As 'cousas' do magnetismo. Semellante á "corrente" na electricidade. Pódese visualizar como "liñas" que saen dun polo e volvendo ao outro.<br />
* '''Furling''' - Unha acción protectora que reduce a exposición a ventos violentos ao enfrontar as aspas lonxe delas.<br />
* '''Jig''' - Un dispositivo usado para manter os imáns no seu lugar antes de colocalos na resina.<br />
* '''Borde de ataque''' - O bordo dunha lámina que golpearía un obxecto colocado no seu camiño cando o rotor xira.<br />
* '''Elevación''' - Forza que exerce o vento sobre un obxecto. A sustentación está en ángulo recto coa dirección do vento no obxecto. (ver Arrastre)<br />
* '''Molde''' - Un recipiente con forma no que se forman fundicións de resina. O molde pódese descartar despois de que a fundición se fixera.<br />
* '''Multímetro''' - Un instrumento de proba eléctrico versátil, usado para medir tensión, corrente e outros parámetros.<br />
* '''Neodimio''' - O nome dado a un tipo de imán permanente que contén neodimio, ferro e boro. Estes imáns son moi fortes e cada vez máis barato.<br />
* '''Offset''' - Unha posición excéntrica, descentrada.<br />
* '''Po de talco'''- Un recheo en po barato que se usa para espesar a resina e retardar a súa reacción (evitar que se sobrequente).<br />
* '''Cola''': unha veleta que se sobresae montada nunha pluma na parte traseira do muíño de vento que se usa para dirixila ou fóra do vento automaticamente.<br />
* '''Tap''' - unha ferramenta para facer rosca dentro dos buratos para poder colocar un parafuso no burato.<br />
* '''Empuxe''' - A forza do vento que empurra a máquina cara atrás.<br />
* '''Torre''' - O mastro que soporta o muíño de vento.<br />
* '''Bordo posterior''': o bordo da lámina máis afastado do bordo de ataque. O bordo de saída está afiado, para liberar o paso aire sen turbulencias.<br />
* '''Cuñas''': pezas cónicas de madeira que se usan para aumentar o grosor da lámina e aumentar o seu ángulo co vento preto da raíz.<br />
* '''Peza de traballo''' - A peza de madeira ou metal que se está a dar forma no taller.<br />
* '''Colamento de guiñada''': o xiro da parte superior da torre na que está montado o muíño de vento. O rodamento de guiñada permite que o muíño se enfronte ao vento.<br />

. == O espazo == <br />
<br />
=== A fundición === <br />
<br />
A Fundición é unha organización sen ánimo de lucro con sede nunha aldea GaliZA anteriormente abandonada. Funciona tanto como residencia como como espazo de proxecto. Subscríbese aos ideais de autoorganización e ten os seguintes tres obxectivos: <br />
1. Organizar actividades no ámbito das artes, as ciencias e as humanidades fóra das institucións tradicionais, centradas no discurso crítico.<br />
2. Promover o intercambio de ideas e a colaboración intelectual fóra das limitacións impostas polo Estado e o mercado.<br />
3. Aumentar a autosuficiencia, a sustentabilidade e a concienciación co medio ambiente utilizando a tecnoloxía axeitada e o código aberto como principais recursos. Tendo en conta este contexto, o noso obxectivo é reforzar a capacidade de xerar redes que flúen do contexto rural ao urbano apoiando os intercambios non xerarquizados e democráticos de coñecementos e prácticas que permitan modelos novos e sostibles no contexto rural. Segundo iso consideramos que o novo creativo transdisciplinar dos sectores nos que estamos enredados poden ter un impacto enorme e positivo na creación deste novo paradigma.<br />
https://bravosfoundry.com/ <br />
Ademais, hai un foco temático na transdisciplinariedade, o transfeminismo e o poshumanismo. Aínda que este enfoque non é axeitadamente comprendido por categorías políticas identitarias como a raza ou o xénero, esperamos que leve á subversión das estruturas hexemónicas inscritas nos binarismos que sosteñen moitas destas categorías. O noso interese reside no desenvolvemento de ferramentas e tecnoloxías que subvertan as estruturas contemporáneas de dominación, explotación e marxinación, non nas que a reproducen. Buscamos desenvolver un entorno máis sostible abrindo as nosas prácticas baseadas nun marco de cultura libre, xerando redes e interese ao seu redor, posibilitando un fluxo de intercambio de innovación entre sectores creativos centrados na revalorización dos contextos rurais e do seu patrimonio de coñecemento. <br />

=== '''Sección 2, implica a construción de pezas do '''alternador''' utilizando os dispositivos da sección 1.''' === <br />
<br />
'''Alternador''' Cada rotor magnético é un disco de aceiro con 12 imáns colocados sobre el e colocados en resina. Os imáns son cada un de 50 x 50 x 20 mm, e só caben no disco. A idea é conseguir a máxima cantidade de fluxo nun espazo determinado. A turbina funciona a 650 rpm para unha saída de 400 W, polo que a forza centrífuga sobre os imáns é 60 veces a forza da gravidade. Para evitar que saian voando, hai que reforzar a fundición de resina. Un cable de aceiro inoxidable colócase arredor da parte exterior dos imáns para manter a fundición xunta a altas revolucións por minuto. Usamos inoxidable porque non é magnético, ou polo menos menos magnético que un cable de aceiro normal. Enrolarás as bobinas que producen a potencia de saída e fundirase en resina para formar un estator entre os dous rotores magnéticos. <br />

<br />
Paso - Xerador, rotor: Preparación do disco metálico. fíxose a máquina na tenda [[File:prod05.jpg|200px]] <br />
Paso - Xerador, rotor: Preparación do cubo da roda. <br />
[[File:frame10.jpg|200px]] '''O cubo da roda''' Podes atopar un cubo de roda traseira de coche usado (Golf, Toyota, etc.) que teña un xeito sinxelo engade o eixe ou, alternativamente, compre un cubos de remolque en liña novos a baixo custo. PCD ou "diámetro do círculo de paso" é o diámetro do círculo do patrón do burato no cubo, e normalmente este será de 100 mm para un cubo de roda de coche, ou de 4 polgadas para un cubo de remolque. Os hubs dos coches poden ter un tambor de freo que non precisa. Isto pódese eliminar usando a disco de corte nunha moedora. O enfoque máis sinxelo é facer catro cortes rectos ao redor os catro orificios na parte frontal, deixando unha superficie cadrada na que se monta o imán rotores. Estas fotos mostran un cubo de roda traseira de golf: primeiro se corta o tambor de freo e a continuación, o cubo acabado despois de cortar o tambor. Un típico cubo de coche de roda traseira con a brida no extremo traseiro do eixe do tronco que se pode reutilizar para montalo. Os cubos de remolque, por outra banda, son de calidade bastante básica, e os rodamentos tamén poden ser barato para uso a longo prazo, pero son artigos facilmente dispoñibles que se poden mercar en liña como novo. Os debuxos que aparecen a continuación (de autow.com) mostran un concentrador e un stub típicos eixe que se compran por separado. Debe estar preparado para substituír os rodamentos por unha marca nomeada (como SKF). É fácil de substituír os conos e rolos internos, pero hai que golpear as capas exteriores suavemente fóra do cubo cunha deriva adecuada. Mantéñaos rectos tocando uniformemente lados opostos e teña coidado de non raiar o asento. Paso - Xerador, rotor: Preparación da plantilla. <br />

4.1 Fabricación das láminas O coitelo é útil para anacos máis grosos de madeira e para cortar nun oco. Pode facer un bo traballo suave da raíz da lámina, mentres que o avión funcionará mellor onde necesitas un acabado moi recto. '''Marcando as estacións''' Coloque a folla co seu mellor bordo cara a vostede na súa superficie superior. Isto en realidade convértese na parte traseira ou "abaixo" da lámina acabada. (A maior parte do lado dianteiro ou de barlovento debe ser cortado, polo que hai defectos neste lado inferior non son importantes.) A raíz da folla estará á túa dereita, a punta á esquerda, a 1000 mm da raíz (preto do extremo esquerdo). Mide dende a raíz e marca catro estacións. Estación A a 75 mm Estación B a 150 mm Estación C a 500 mm A punta a 1000 mm. En cada estación debuxa unha liña ao redor da peza usando un cadrado. <br />
<br />
[[File:01tur.jpeg|400px]] <br />
<br />
<br />
'''Afilando a folla''' O ancho da folla diminúe desde o tamaño completo na estación C ata 55 mm de ancho na estación punta. Marque o ancho da punta de 55 mm, medindo dende o lado do bordo de ataque. Debuxa unha liña aínda que a túa marca ao lado do bordo posterior na estación C e corta unha peza triangular así como para conseguir a forma cónica correcta para a folla. Calquera nós no triangular o corte non importa xa que esta peza é descartada. Tenta facer este corte "cadrado", perpendicular á superficie posterior da lámina. Podes facelo cunha serra circular ou cortando e afeitando transversalmente como se describe arriba.<br />
<br />
[[File:02tur.jpeg|400px]] '''Marcando os bordos de entrada e de saída''' O seguinte paso é cortar a cara de barlovento da lámina. Esta cara está definida polo liñas de bordo de ataque e de saída da lámina. Estas liñas deben estar marcadas con referencia á cara posterior da madeira que estivo máis arriba na anterior operación. Darlle a volta á madeira. Comeza trazando dúas liñas diagonais entre as estacións A e B na parte dianteira ou a barlovento (ver máis abaixo). Un está na cara frontal e o outro na cara o bordo de saída que agora está cara a ti. <br />
[[File:03tur.jpeg|400px]] <br />
<br />
Agora debuxa a liña do bordo de ataque como se mostra a continuación, desde a estación B, ata 16 mm (desde atrás) na estación C, e despois continúa ata a punta en 7 mm de atrás. [[Ficheiro:04tur.jpeg|400px]] (Este debuxo non mostra o bit extra máis aló da punta que pode quedar na súa peza de traballo real). As medidas resúmense nesta táboa a continuación. As alturas son dende a parte traseira folla que despois descansará no banco. Elimina a madeira por encima desta altura. "Cheo" refírese ao grosor total da peza de madeira orixinal que está a usar. [[File:05tur.jpeg|400px]] '''O rastro''' A liña do bordo posterior comeza na parte inferior da liña diagonal na estación B e sobe a 5 mm en C, continuando a 5 mm ata a punta. Esta vista abaixo mostra a madeira xa eliminado entre as dúas liñas para formar a cara barlovento da pala. [[File:06tur.png|400px]] <br />
<br />
Esculpe esta cara de barlovento plana entre as dúas liñas. Coida que os bordos estean recto, seguindo as liñas. A mellor ferramenta para usar para rematar a parte exterior do a lámina é un plano, para dar un acabado suave e recto. Quizais necesites traballar no avión 45 graos coa peza de traballo, deslizando parcialmente cara aos lados, para formar a forma oca en estación C. Este paso complétase cando podes colocar unha regra pola cara entre os principais e liñas de bordo de saída e non hai "xoroba" no medio. Encha calquera chip ou pequeno ocos con recheo de madeira. Se hai algún erro grave, ou k grande non que se debilitan a folla, entón pode ter que ser descartada. Comprobe a "caída" usando un nivel como referencia. Suxeitar a madeira para que a parte da raíz sitúase nivelado e mida a diferenza de nivel entre os bordos de entrada e de saída. A diferenza ou "caída" debe ser de 11 mm no punto medio de 500 mm e de 2 mm no punta. <gallery mode="packed-hover" heights=320px><br />

''Pedagoxías do vento e das estrelas. As relacións sociais ás que (nunca estabamos destinados) a sobrevivir, tamén viven nos nosos corpos dolorosamente, e Audre Lorde non está aquí para lembrarnos esta lección, salvo na medida en que está presente no vento pedagóxico. Pero o vento é o noso mestre (74). -Alexis Pauline Gumbs'' do libro Mapping Queer Space(s) of Praxis and Pedagogy Editores: Elizabeth McNeil, James E. Wermers, Joshua O. Lunn'' <br />
<br />
<br />
Temos o pracer de comunicarvos que do 16 ao 29 de outubro Pin Biotranslab, Casa do Río e The Foundry establece unha colaboración para levar a cabo o evento Eco (i) Logic Queer Energy harvesting. O proxecto é posible grazas ao apoio de GOSH, unha rede para desenvolver e difundir proxectos baseados en hardware de código aberto para a ciencia. '''Eco (i) Logic Queer Recollida de enerxía''' O evento ten como obxectivo abordar a falta de mulleres, queer, trans e diversidade nos ámbitos tecnolóxicos en xeral e do hacking máis concretamente. Pero aínda máis, pretende crear unha comunidade que avalía criticamente as narrativas hexemónicas arredor das tecnoloxías, os aspectos de modernidade dos seus supostos occidentais subliñados e as súas inflexións capitalistas inherentes, entre outros. O obxectivo principal do evento é desenvolver kits que se centren na interacción co medio natural no ámbito da enerxía.. o obxectivo principal pasa pola captación de enerxía do medio natural, a través dos aeroxeradores. Estes kits de enerxía serán escalables e poderán utilizarse tanto como material pedagóxico como para instalar centrais eléctricas específicas do sitio en diferentes sitios tamén. Este traballo ten un compoñente contrainfraestrutural: unha posible consecuencia sería capacitar ás persoas para xerar a súa propia enerxía en lugar de depender de grandes empresas e moitas veces extractivas. <br />
<br />
== Introdución e valores do proceso == <br />
<br />
Aquí comeza a documentación do longo proceso de creación de prototipos do modelo Hugh Piggott The Piggott Turbine - Wind Empowerment dunha turbina eólica de código aberto. Estivemos cambiando un pouco os obxectivos do evento, pasando de desenvolver pequenos kits para ir a construír o aeroxerador de 2 m de tamaño real para proporcionar enerxía ás áreas rexionais rurais nas que estabamos traballando. Nese evento concreto estivemos traballando en The Foundry un bonito proxecto e asociación que instalamos no norte de GaliZA ao noroeste de España. Durante o evento activáronse moitas cousas entre os realizadores e os visitantes; En xeral foi unha experiencia marabillosa chea de cousas novas que estudar, aprender, facer e comprender xuntos. Escollemos este modelo porque estaba cheo de capas de interese nos niveis de aprendizaxe, comprensión e elaboración, aquí algúns niveis mesturados con capas: en primeiro lugar é un dos que é '''de código aberto''' ou polo menos ten a opción de acceder á documentación completa. realmente '''ricos a nivel pedagóxico''', realmente estivemos aprendendo a través da construción completa do propio xerador, sobre moitos temas como: <br />
<br />
* electromagnetismo *matemáticas * xeometría * electrónica * AC-DC *soldadura * talla en madeira * escultura e fundición de pezas e moito máis que foi alcanzando a través do agradable proceso de ler, aprender e construír xuntos.<br />
<br />
== Glosario == <br />
* '''AC-'''Corrente alterna producida polo alternador. Todos os fíos: palabra estadounidense para varilla ou tachuelas "roscadas" ou "hiladas".<br />
* '''Interruptor de freo''' - Interruptor usado para curtocircuitar os cables do alternador para que se pare.<br />
* '''Catalizador''' - Un produto químico usado para facer sólido o conxunto de resinas de poliéster. O catalizador reacciona co "acelerador" xa presente na mestura de resina. A calor de reacción establece o poliéster.<br />
* '''Cavalier''' - Unha marca de coche. O cavalier no Reino Unido non é o mesmo que o Cavalier nos EUA, pero ambos teñen cubos de roda útiles.<br />
* '''DC - corrente continua''' cun lado positivo e outro negativo, como nos circuítos de batería.<br />
* '''Diámetro''' - A distancia dun lado a outro dun círculo. O ancho dun disco no medio.<br />
* '''Fase''' - O tempo da alternancia cíclica da tensión nun circuíto. As diferentes fases alcanzarán o pico en diferentes momentos.<br />
* '''Poliéster''' - Un tipo de resina utilizada no traballo de fibra de vidro. Tamén apto para facer fundicións.<br />

* '''Soldadura''': un método para facer conexións eléctricas entre fíos usando un 'ferro' quente e recubrindo todo con soldadura fundida.<br />
* '''Arrastre''' - Forza que exerce o vento sobre un obxecto. O arrastre é paralelo á dirección do vento no obxecto. (ver Ascensor)<br />
* '''Estator''' - Un conxunto de bobinas incrustadas nunha lousa de resina para formar parte do alternador. Os imáns inducen unha tensión nas bobinas e podemos utilizala para cargar unha batería. * '''Gota''': úsase aquí para describir unha determinada medida da forma da lámina dun muíño de vento. A "caída" afecta o ángulo de a lámina ao vento. Monómero de estireno - Un disolvente con cheiro desagradable na mestura de resina de poliéster.<br />
* '''Flux''' - As 'cousas' do magnetismo. Semellante á "corrente" na electricidade. Pódese visualizar como "liñas" que saen dun polo e volvendo ao outro.<br />
* '''Furling''' - Unha acción protectora que reduce a exposición a ventos violentos ao enfrontar as aspas lonxe delas.<br />
* '''Jig''' - Un dispositivo usado para manter os imáns no seu lugar antes de colocalos na resina.<br />

* '''Offset''' - Unha posición excéntrica, descentrada.<br />
* '''Po de talco'''- Un recheo en po barato que se usa para espesar a resina e retardar a súa reacción (evitar que se sobrequente).<br />
* '''Cola''': unha veleta que se sobresae montada nunha pluma na parte traseira do muíño de vento que se usa para dirixila ou fóra do vento automaticamente.<br />
* '''Tap''' - unha ferramenta para facer rosca dentro dos buratos para poder colocar un parafuso no burato.<br />
* '''Empuxe''' - A forza do vento que empurra a máquina cara atrás.<br />
* '''Torre''' - O mastro que soporta o muíño de vento.<br />
* '''Bordo posterior''': o bordo da lámina máis afastado do bordo de ataque. O bordo de saída está afiado, para liberar o paso aire sen turbulencias.<br />
* '''Cuñas''': pezas cónicas de madeira que se usan para aumentar o grosor da lámina e aumentar o seu ángulo co vento preto da raíz.<br />
* '''Peza de traballo''' - A peza de madeira ou metal que se está a dar forma no taller.<br />
* '''Colamento de guiñada''': o xiro da parte superior da torre na que está montado o muíño de vento. O rodamento de guiñada permite que o muíño se enfronte ao vento.<br />

. == O espazo == <br />
<br />
=== A fundición === <br />
<br />
A Fundición é unha organización sen ánimo de lucro con sede nunha aldea GaliZA anteriormente abandonada. Funciona tanto como residencia como como espazo de proxecto. Subscríbese aos ideais de autoorganización e ten os seguintes tres obxectivos: <br />
1. Organizar actividades no ámbito das artes, as ciencias e as humanidades fóra das institucións tradicionais, centradas no discurso crítico.<br />
2. Promover o intercambio de ideas e a colaboración intelectual fóra das limitacións impostas polo Estado e o mercado.<br />
3. Aumentar a autosuficiencia, a sustentabilidade e a concienciación co medio ambiente utilizando a tecnoloxía axeitada e o código aberto como principais recursos. Tendo en conta este contexto, o noso obxectivo é reforzar a capacidade de xerar redes que flúen do contexto rural ao urbano apoiando os intercambios non xerarquizados e democráticos de coñecementos e prácticas que permitan modelos novos e sostibles no contexto rural. Segundo iso consideramos que o novo creativo transdisciplinar dos sectores nos que estamos enredados poden ter un impacto enorme e positivo na creación deste novo paradigma.<br />
https://bravosfoundry.com/ <br />
Ademais, hai un foco temático na transdisciplinariedade, o transfeminismo e o poshumanismo. Aínda que este enfoque non é axeitadamente comprendido por categorías políticas identitarias como a raza ou o xénero, esperamos que leve á subversión das estruturas hexemónicas inscritas nos binarismos que sosteñen moitas destas categorías. O noso interese reside no desenvolvemento de ferramentas e tecnoloxías que subvertan as estruturas contemporáneas de dominación, explotación e marxinación, non nas que a reproducen. Buscamos desenvolver un entorno máis sostible abrindo as nosas prácticas baseadas nun marco de cultura libre, xerando redes e interese ao seu redor, posibilitando un fluxo de intercambio de innovación entre sectores creativos centrados na revalorización dos contextos rurais e do seu patrimonio de coñecemento. <br />

=== '''Sección 2, implica a construción de pezas do '''alternador''' utilizando os dispositivos da sección 1.''' === <br />
<br />
'''Alternador''' Cada rotor magnético é un disco de aceiro con 12 imáns colocados sobre el e colocados en resina. Os imáns son cada un de 50 x 50 x 20 mm, e só caben no disco. A idea é conseguir a máxima cantidade de fluxo nun espazo determinado. A turbina funciona a 650 rpm para unha saída de 400 W, polo que a forza centrífuga sobre os imáns é 60 veces a forza da gravidade. Para evitar que saian voando, hai que reforzar a fundición de resina. Un cable de aceiro inoxidable colócase arredor da parte exterior dos imáns para manter a fundición xunta a altas revolucións por minuto. Usamos inoxidable porque non é magnético, ou polo menos menos magnético que un cable de aceiro normal. Enrolarás as bobinas que producen a potencia de saída e fundirase en resina para formar un estator entre os dous rotores magnéticos. <br />

<br />
Paso - Xerador, rotor: Preparación do disco metálico. fíxose a máquina na tenda [[Ficheiro:prod05.jpg|200px]] <br />
<br />
Paso - Xerador, rotor: Preparación do cubo da roda. <br />
[[Ficheiro:frame10.jpg|200px]] '''O cubo da roda''' Podes atopar un cubo de roda traseira de coche usado (Golf, Toyota, etc.) que teña un xeito sinxelo engade o eixe ou, alternativamente, compre un cubos de remolque en liña novos a baixo custo. PCD ou "diámetro do círculo de paso" é o diámetro do círculo do patrón do burato no cubo, e normalmente este será de 100 mm para un cubo de roda de coche, ou de 4 polgadas para un cubo de remolque. Os hubs dos coches poden ter un tambor de freo que non precisa. Isto pódese eliminar usando a disco de corte nunha moedora. O enfoque máis sinxelo é facer catro cortes rectos ao redor os catro orificios na parte frontal, deixando unha superficie cadrada na que se monta o imán rotores. Estas fotos mostran un cubo de roda traseira de golf: primeiro se corta o tambor de freo e a continuación, o cubo acabado despois de cortar o tambor. Un típico cubo de coche de roda traseira con a brida no extremo traseiro do eixe do tronco que se pode reutilizar para montalo. Os cubos de remolque, por outra banda, son de calidade bastante básica, e os rodamentos tamén poden ser barato para uso a longo prazo, pero son artigos facilmente dispoñibles que se poden mercar en liña como novo. Os debuxos que aparecen a continuación (de autow.com) mostran un concentrador e un stub típicos eixe que se compran por separado. Debe estar preparado para substituír os rodamentos por unha marca nomeada (como SKF). É fácil de substituír os conos e rolos internos, pero hai que golpear as capas exteriores suavemente fóra do cubo cunha deriva adecuada. Mantéñaos rectos tocando uniformemente lados opostos e teña coidado de non raiar o asento.

<br />
4.1 Fabricación das láminas O coitelo é útil para anacos máis grosos de madeira e para cortar nun oco. Pode facer un bo traballo suave da raíz da lámina, mentres que o avión funcionará mellor onde necesitas un acabado moi recto. '''Marcando as estacións''' Coloque a folla co seu mellor bordo cara a vostede na súa superficie superior. Isto en realidade convértese na parte traseira ou "abaixo" da lámina acabada. (A maior parte do lado dianteiro ou de barlovento debe ser cortado, polo que hai defectos neste lado inferior non son importantes.) A raíz da folla estará á túa dereita, a punta á esquerda, a 1000 mm da raíz (preto do extremo esquerdo). Mide dende a raíz e marca catro estacións. Estación A a 75 mm Estación B a 150 mm Estación C a 500 mm A punta a 1000 mm. En cada estación debuxa unha liña ao redor da peza usando un cadrado. [[Ficheiro:01tur.jpeg|400px]] '''Afilando a folla''' O ancho da folla diminúe desde o tamaño completo na estación C ata 55 mm de ancho na estación punta. Marque o ancho da punta de 55 mm, medindo dende o lado do bordo de ataque. Debuxa unha liña aínda que a túa marca ao lado do bordo posterior na estación C e corta unha peza triangular así como para conseguir a forma cónica correcta para a folla. Calquera nós no triangular o corte non importa xa que esta peza é descartada. Tenta facer este corte "cadrado", perpendicular á superficie posterior da lámina. Podes facelo cunha serra circular ou cortando e afeitando transversalmente como se describe arriba.<br />
[[Ficheiro:02tur.jpeg|400px]] '''Marcando os bordos de entrada e de saída''' O seguinte paso é cortar a cara de barlovento da lámina. Esta cara está definida polo liñas de bordo de ataque e de saída da lámina. Estas liñas deben estar marcadas con referencia á cara posterior da madeira que estivo máis arriba na anterior operación. Darlle a volta á madeira. Comeza trazando dúas liñas diagonais entre as estacións A e B na parte dianteira ou a barlovento (ver máis abaixo). Un está na cara frontal e o outro na cara o bordo de saída que agora está cara a ti. <br />
[[Ficheiro:03tur.jpeg|400px]] <br />
<br />
Agora debuxa a liña do bordo de ataque como se mostra a continuación, desde a estación B, ata 16 mm (desde atrás) na estación C, e despois continúa ata a punta en 7 mm de atrás. [[Ficheiro:04tur.jpeg|400px]] (Este debuxo non mostra o bit extra máis aló da punta que pode quedar na súa peza de traballo real). As medidas resúmense nesta táboa a continuación. As alturas son dende a parte traseira folla que despois descansará no banco. Elimina a madeira por encima desta altura. "Cheo" refírese ao grosor total da peza de madeira orixinal que está a usar. [[Ficheiro:05tur.jpeg|400px]] '''O rastro''' A liña do bordo posterior comeza na parte inferior da liña diagonal na estación B e sobe a 5 mm en C, continuando a 5 mm ata a punta. Esta vista abaixo mostra a madeira xa eliminado entre as dúas liñas para formar a cara barlovento da pala. [[Ficheiro:06tur.png|400px]] Esculpe esta cara de barlovento plana entre as dúas liñas. Coida que os bordos estean recto, seguindo as liñas. A mellor ferramenta para usar para rematar a parte exterior do a lámina é un plano, para dar un acabado suave e recto. Quizais necesites traballar no avión 45 graos coa peza de traballo, deslizando parcialmente cara aos lados, para formar a forma oca en estación C. Este paso complétase cando podes colocar unha regra pola cara entre os principais e liñas de bordo de saída e non hai "xoroba" no medio. Encha calquera chip ou pequeno ocos con recheo de madeira. Se hai algún erro grave, ou k grande non que se debilitan a folla, entón pode ter que ser descartada. Comprobe a "caída" usando un nivel como referencia. Suxeitar a madeira para que a parte da raíz sitúase nivelado e mida a diferenza de nivel entre os bordos de entrada e de saída. A diferenza ou "caída" debe ser de 11 mm no punto medio de 500 mm e de 2 mm no punta. <gallery mode="packed-hover" heights=320px> Ficheiro:Blade01.png Ficheiro:Blade02.png Ficheiro:Blade03.png Ficheiro:Blades01.jpg </galería> <br />

''Pedagoxías do vento e das estrelas. As relacións sociais ás que (nunca estabamos destinados) a sobrevivir, tamén viven nos nosos corpos dolorosamente, e Audre Lorde non está aquí para lembrarnos esta lección, salvo na medida en que está presente no vento pedagóxico. Pero o vento é o noso mestre (74). -Alexis Pauline Gumbs'' do libro Mapping Queer Space(s) of Praxis and Pedagogy Editores: Elizabeth McNeil, James E. Wermers, Joshua O. Lunn'' <br />
<br />
<br />
Temos o pracer de comunicarvos que do 16 ao 29 de outubro Pin Biotranslab, Casa do Río e The Foundry establece unha colaboración para levar a cabo o evento Eco (i) Logic Queer Energy harvesting. O proxecto é posible grazas ao apoio de GOSH, unha rede para desenvolver e difundir proxectos baseados en hardware de código aberto para a ciencia. '''Eco (i) Logic Queer Recollida de enerxía''' O evento ten como obxectivo abordar a falta de mulleres, queer, trans e diversidade nos ámbitos tecnolóxicos en xeral e do hacking máis concretamente. Pero aínda máis, pretende crear unha comunidade que avalía criticamente as narrativas hexemónicas arredor das tecnoloxías, os aspectos de modernidade dos seus supostos occidentais subliñados e as súas inflexións capitalistas inherentes, entre outros. O obxectivo principal do evento é desenvolver kits que se centren na interacción co medio natural no ámbito da enerxía.. o obxectivo principal pasa pola captación de enerxía do medio natural, a través dos aeroxeradores. Estes kits de enerxía serán escalables e poderán utilizarse tanto como material pedagóxico como para instalar centrais eléctricas específicas do sitio en diferentes sitios tamén. Este traballo ten un compoñente contrainfraestrutural: unha posible consecuencia sería capacitar ás persoas para xerar a súa propia enerxía en lugar de depender de grandes empresas e moitas veces extractivas. <br />
<br />
== Introdución e valores do proceso == <br />
<br />
Aquí comeza a documentación do longo proceso de creación de prototipos do modelo Hugh Piggott The Piggott Turbine - Wind Empowerment dunha turbina eólica de código aberto. Estivemos cambiando un pouco os obxectivos do evento, pasando de desenvolver pequenos kits para ir a construír o aeroxerador de 2 m de tamaño real para proporcionar enerxía ás áreas rexionais rurais nas que estabamos traballando. Nese evento concreto estivemos traballando en The Foundry un bonito proxecto e asociación que instalamos no norte de GaliZA ao noroeste de España. Durante o evento activáronse moitas cousas entre os realizadores e os visitantes; En xeral foi unha experiencia marabillosa chea de cousas novas que estudar, aprender, facer e comprender xuntos. Escollemos este modelo porque estaba cheo de capas de interese nos niveis de aprendizaxe, comprensión e elaboración, aquí algúns niveis mesturados con capas: en primeiro lugar é un dos que é '''de código aberto''' ou polo menos ten a opción de acceder á documentación completa. realmente '''ricos a nivel pedagóxico''', realmente estivemos aprendendo a través da construción completa do propio xerador, sobre moitos temas como: <br />
<br />
* electromagnetismo *matemáticas * xeometría * electrónica * AC-DC *soldadura * talla en madeira * escultura e fundición de pezas e moito máis que foi alcanzando a través do agradable proceso de ler, aprender e construír xuntos.<br />
<br />
== Glosario == <br />
* '''AC-'''Corrente alterna producida polo alternador. Todos os fíos: palabra estadounidense para varilla ou tachuelas "roscadas" ou "hiladas".<br />
* '''Interruptor de freo''' - Interruptor usado para curtocircuitar os cables do alternador para que se pare.<br />
* '''Catalizador''' - Un produto químico usado para facer sólido o conxunto de resinas de poliéster. O catalizador reacciona co "acelerador" xa presente na mestura de resina. A calor de reacción establece o poliéster.<br />
* '''Cavalier''' - Unha marca de coche. O cavalier no Reino Unido non é o mesmo que o Cavalier nos EUA, pero ambos teñen cubos de roda útiles.<br />
* '''DC - corrente continua''' cun lado positivo e outro negativo, como nos circuítos de batería.<br />
* '''Diámetro''' - A distancia dun lado a outro dun círculo. O ancho dun disco no medio.<br />
* '''Fase''' - O tempo da alternancia cíclica da tensión nun circuíto. As diferentes fases alcanzarán o pico en diferentes momentos.<br />
* '''Poliéster''' - Un tipo de resina utilizada no traballo de fibra de vidro. Tamén apto para facer fundicións.<br />
* '''Potencia''' - a taxa de entrega de enerxía<br />
* '''Rectifier''' - Un dispositivo semicondutor que converte AC en DC para cargar a batería.<br />
* '''Raíz''' - A parte máis ancha da lámina preto do cubo no centro do rotor.<br />
* '''Rotor''' - Unha parte xiratoria. Os rotores de imáns son os discos de aceiro que transportan os imáns máis alá do estator. As palas do rotor son a "hélice" impulsado polo vento e impulsando os rotores magnéticos.<br />
* '''Soldadura''': un método para facer conexións eléctricas entre fíos usando un 'ferro' quente e recubrindo todo con soldadura fundida.<br />
* '''Arrastre''' - Forza que exerce o vento sobre un obxecto. O arrastre é paralelo á dirección do vento no obxecto. (ver Ascensor)<br />
* '''Estator''' - Un conxunto de bobinas incrustadas nunha lousa de resina para formar parte do alternador. Os imáns inducen unha tensión nas bobinas e podemos utilizala para cargar unha batería. * '''Gota''': úsase aquí para describir unha determinada medida da forma da lámina dun muíño de vento. A "caída" afecta o ángulo de a lámina ao vento. Monómero de estireno - Un disolvente con cheiro desagradable na mestura de resina de poliéster.<br />
* '''Flux''' - As 'cousas' do magnetismo. Semellante á "corrente" na electricidade. Pódese visualizar como "liñas" que saen dun polo e volvendo ao outro.<br />
* '''Furling''' - Unha acción protectora que reduce a exposición a ventos violentos ao enfrontar as aspas lonxe delas.<br />
* '''Jig''' - Un dispositivo usado para manter os imáns no seu lugar antes de colocalos na resina.<br />
* '''Borde de ataque''' - O bordo dunha lámina que golpearía un obxecto colocado no seu camiño cando o rotor xira.<br />
* '''Elevación''' - Forza que exerce o vento sobre un obxecto. A sustentación está en ángulo recto coa dirección do vento no obxecto. (ver Arrastre)<br />
* '''Molde''' - Un recipiente con forma no que se forman fundicións de resina. O molde pódese descartar despois de que a fundición se fixera.<br />
* '''Multímetro''' - Un instrumento de proba eléctrico versátil, usado para medir tensión, corrente e outros parámetros.<br />
* '''Neodimio''' - O nome dado a un tipo de imán permanente que contén neodimio, ferro e boro. Estes imáns son moi fortes e cada vez máis barato.<br />
* '''Offset''' - Unha posición excéntrica, descentrada.<br />
* '''Po de talco'''- Un recheo en po barato que se usa para espesar a resina e retardar a súa reacción (evitar que se sobrequente).<br />
* '''Cola''': unha veleta que se sobresae montada nunha pluma na parte traseira do muíño de vento que se usa para dirixila ou fóra do vento automaticamente.<br />
* '''Tap''' - unha ferramenta para facer rosca dentro dos buratos para poder colocar un parafuso no burato.<br />
* '''Empuxe''' - A forza do vento que empurra a máquina cara atrás.<br />
* '''Torre''' - O mastro que soporta o muíño de vento.<br />
* '''Bordo posterior''': o bordo da lámina máis afastado do bordo de ataque. O bordo de saída está afiado, para liberar o paso aire sen turbulencias.<br />
* '''Cuñas''': pezas cónicas de madeira que se usan para aumentar o grosor da lámina e aumentar o seu ángulo co vento preto da raíz.<br />
* '''Peza de traballo''' - A peza de madeira ou metal que se está a dar forma no taller.<br />
* '''Colamento de guiñada''': o xiro da parte superior da torre na que está montado o muíño de vento. O rodamento de guiñada permite que o muíño se enfronte ao vento.<br />

. == O espazo == <br />
<br />
=== A fundición === <br />
<br />
A Fundición é unha organización sen ánimo de lucro con sede nunha aldea GaliZA anteriormente abandonada. Funciona tanto como residencia como como espazo de proxecto. Subscríbese aos ideais de autoorganización e ten os seguintes tres obxectivos: <br />
1. Organizar actividades no ámbito das artes, as ciencias e as humanidades fóra das institucións tradicionais, centradas no discurso crítico.<br />
2. Promover o intercambio de ideas e a colaboración intelectual fóra das limitacións impostas polo Estado e o mercado.<br />
3. Aumentar a autosuficiencia, a sustentabilidade e a concienciación co medio ambiente utilizando a tecnoloxía axeitada e o código aberto como principais recursos. Tendo en conta este contexto, o noso obxectivo é reforzar a capacidade de xerar redes que flúen do contexto rural ao urbano apoiando os intercambios non xerarquizados e democráticos de coñecementos e prácticas que permitan modelos novos e sostibles no contexto rural. Segundo iso consideramos que o novo creativo transdisciplinar dos sectores nos que estamos enredados poden ter un impacto enorme e positivo na creación deste novo paradigma.<br />
https://bravosfoundry.com/ <br />
Ademais, hai un foco temático na transdisciplinariedade, o transfeminismo e o poshumanismo. Aínda que este enfoque non é axeitadamente comprendido por categorías políticas identitarias como a raza ou o xénero, esperamos que leve á subversión das estruturas hexemónicas inscritas nos binarismos que sosteñen moitas destas categorías. O noso interese reside no desenvolvemento de ferramentas e tecnoloxías que subvertan as estruturas contemporáneas de dominación, explotación e marxinación, non nas que a reproducen. Buscamos desenvolver un entorno máis sostible abrindo as nosas prácticas baseadas nun marco de cultura libre, xerando redes e interese ao seu redor, posibilitando un fluxo de intercambio de innovación entre sectores creativos centrados na revalorización dos contextos rurais e do seu patrimonio de coñecemento. <br />

=== '''Sección 2, implica a construción de pezas do '''alternador''' utilizando os dispositivos da sección 1.''' === <br />
<br />
'''Alternador''' Cada rotor magnético é un disco de aceiro con 12 imáns colocados sobre el e colocados en resina. Os imáns son cada un de 50 x 50 x 20 mm, e só caben no disco. A idea é conseguir a máxima cantidade de fluxo nun espazo determinado. A turbina funciona a 650 rpm para unha saída de 400 W, polo que a forza centrífuga sobre os imáns é 60 veces a forza da gravidade. Para evitar que saian voando, hai que reforzar a fundición de resina. Un cable de aceiro inoxidable colócase arredor da parte exterior dos imáns para manter a fundición xunta a altas revolucións por minuto. Usamos inoxidable porque non é magnético, ou polo menos menos magnético que un cable de aceiro normal. Enrolarás as bobinas que producen a potencia de saída e fundirase en resina para formar un estator entre os dous rotores magnéticos. <br />

<br />
Paso - Xerador, rotor: Preparación do disco metálico. fíxose a máquina na tenda [[Ficheiro:prod05.jpg|200px]] <br />
<br />
Paso - Xerador, rotor: Preparación do cubo da roda. <br />
[[Ficheiro:frame10.jpg|200px]] '''O cubo da roda''' Podes atopar un cubo de roda traseira de coche usado (Golf, Toyota, etc.) que teña un xeito sinxelo engade o eixe ou, alternativamente, compre un cubos de remolque en liña novos a baixo custo. PCD ou "diámetro do círculo de paso" é o diámetro do círculo do patrón do burato no cubo, e normalmente este será de 100 mm para un cubo de roda de coche, ou de 4 polgadas para un cubo de remolque. Os hubs dos coches poden ter un tambor de freo que non precisa. Isto pódese eliminar usando a disco de corte nunha moedora. O enfoque máis sinxelo é facer catro cortes rectos ao redor os catro orificios na parte frontal, deixando unha superficie cadrada na que se monta o imán rotores. Estas fotos mostran un cubo de roda traseira de golf: primeiro se corta o tambor de freo e a continuación, o cubo acabado despois de cortar o tambor. Un típico cubo de coche de roda traseira con a brida no extremo traseiro do eixe do tronco que se pode reutilizar para montalo. Os cubos de remolque, por outra banda, son de calidade bastante básica, e os rodamentos tamén poden ser barato para uso a longo prazo, pero son artigos facilmente dispoñibles que se poden mercar en liña como novo. Os debuxos que aparecen a continuación (de autow.com) mostran un concentrador e un stub típicos eixe que se compran por separado. Debe estar preparado para substituír os rodamentos por unha marca nomeada (como SKF). É fácil de substituír os conos e rolos internos, pero hai que golpear as capas exteriores suavemente fóra do cubo cunha deriva adecuada. Mantéñaos rectos tocando uniformemente lados opostos e teña coidado de non raiar o asento.

=== Sección 4, implica o desexo das palas e a soldadura da base para o xerador de turbina. === <br />
<br />
4.1 Fabricación das láminas O coitelo é útil para anacos máis grosos de madeira e para cortar nun oco. Pode facer un bo traballo suave da raíz da lámina, mentres que o avión funcionará mellor onde necesitas un acabado moi recto. '''Marcando as estacións''' Coloque a folla co seu mellor bordo cara a vostede na súa superficie superior. Isto en realidade convértese na parte traseira ou "abaixo" da lámina acabada. (A maior parte do lado dianteiro ou de barlovento debe ser cortado, polo que hai defectos neste lado inferior non son importantes.) A raíz da folla estará á túa dereita, a punta á esquerda, a 1000 mm da raíz (preto do extremo esquerdo). Mide dende a raíz e marca catro estacións. Estación A a 75 mm Estación B a 150 mm Estación C a 500 mm A punta a 1000 mm. En cada estación debuxa unha liña ao redor da peza usando un cadrado. [[Ficheiro:01tur.jpeg|400px]] '''Afilando a folla''' O ancho da folla diminúe desde o tamaño completo na estación C ata 55 mm de ancho na estación punta. Marque o ancho da punta de 55 mm, medindo dende o lado do bordo de ataque. Debuxa unha liña aínda que a túa marca ao lado do bordo posterior na estación C e corta unha peza triangular así como para conseguir a forma cónica correcta para a folla. Calquera nós no triangular o corte non importa xa que esta peza é descartada. Tenta facer este corte "cadrado", perpendicular á superficie posterior da lámina. Podes facelo cunha serra circular ou cortando e afeitando transversalmente como se describe arriba.<br />
[[Ficheiro:02tur.jpeg|400px]] '''Marcando os bordos de entrada e de saída''' O seguinte paso é cortar a cara de barlovento da lámina. Esta cara está definida polo liñas de bordo de ataque e de saída da lámina. Estas liñas deben estar marcadas con referencia á cara posterior da madeira que estivo máis arriba na anterior operación. Darlle a volta á madeira. Comeza trazando dúas liñas diagonais entre as estacións A e B na parte dianteira ou a barlovento (ver máis abaixo). Un está na cara frontal e o outro na cara o bordo de saída que agora está cara a ti. <br />
[[Ficheiro:03tur.jpeg|400px]] <br />
<br />
Agora debuxa a liña do bordo de ataque como se mostra a continuación, desde a estación B, ata 16 mm (desde atrás) na estación C, e despois continúa ata a punta en 7 mm de atrás. [[Ficheiro:04tur.jpeg|400px]] (Este debuxo non mostra o bit extra máis aló da punta que pode quedar na súa peza de traballo real). As medidas resúmense nesta táboa a continuación. As alturas son dende a parte traseira folla que despois descansará no banco. Elimina a madeira por encima desta altura. "Cheo" refírese ao grosor total da peza de madeira orixinal que está a usar. [[Ficheiro:05tur.jpeg|400px]] '''O rastro''' A liña do bordo posterior comeza na parte inferior da liña diagonal na estación B e sobe a 5 mm en C, continuando a 5 mm ata a punta. Esta vista abaixo mostra a madeira xa eliminado entre as dúas liñas para formar a cara barlovento da pala. [[Ficheiro:06tur.png|400px]] Esculpe esta cara de barlovento plana entre as dúas liñas. Coida que os bordos estean recto, seguindo as liñas. A mellor ferramenta para usar para rematar a parte exterior do a lámina é un plano, para dar un acabado suave e recto. Quizais necesites traballar no avión 45 graos coa peza de traballo, deslizando parcialmente cara aos lados, para formar a forma oca en estación C. Este paso complétase cando podes colocar unha regra pola cara entre os principais e liñas de bordo de saída e non hai "xoroba" no medio. Encha calquera chip ou pequeno ocos con recheo de madeira. Se hai algún erro grave, ou k grande non que se debilitan a folla, entón pode ter que ser descartada. Comprobe a "caída" usando un nivel como referencia. Suxeitar a madeira para que a parte da raíz sitúase nivelado e mida a diferenza de nivel entre os bordos de entrada e de saída. A diferenza ou "caída" debe ser de 11 mm no punto medio de 500 mm e de 2 mm no punta. <gallery mode="packed-hover" heights=320px> Ficheiro:Blade01.png Ficheiro:Blade02.png Ficheiro:Blade03.png Ficheiro:Blades01.jpg </galería> <br />

''Pedagogies of the Wind and Stars. The social relations that we (were never meant to) survive, also live in our bodies painfully, and Audre Lorde is not here to remind us of this lesson herself, except in as much that she is present in the pedagogical wind. But wind is our teacher (74). -Alexis Pauline Gumbs'' from the book Mapping Queer Space(s) of Praxis and Pedagogy <br />
Editors: Elizabeth McNeil, James E. Wermers, Joshua O. Lunn'' <br />
<br />
We have the pleasure to communicate you that from 16 to 29 of October Pin Biotranslab, Casa do Río e The Foundry establishes a collaboration to run the event Eco (i) Logic Queer Energy harvesting. The project is possible thanks to the support of GOSH, an network for develop and disseminate projects based on Open Source hardware for Science.<br />
<br />
'''Eco (i) Logic Queer Energy harvesting''' <br />
The event aims at addressing the lack of women, queer, trans and diversity in technological fields in general and hacking more specifically. But even more so, it aims at creating a community that critically assesses the hegemonic narratives around technologies, the modernity aspects of its underlining Western assumptions and its inherent capitalist inflections, among others.<br />
The main purpose of the event is to develop kits that focus on interacting with the natural environment on the field of energy.. the main objective lies on harvesting energy of the natural environment, through wind turbines. These power kits will be scalable and can be used both as pedagogical material and to set up site-specific power plants in different sites as well. There is a counter-infrastructural component to this work: one possible consequence would be to empower people to generate their own energy instead of relying on large and often extractive companies.<br />
<br />
== Introduction and values of the process ==<br />
<br />
Here starts the documentation of the long process of the prototyping the Hugh Piggott The Piggott Turbine – Wind Empowerment model of an Open source wind turbine. We were changing a bit the goals of the event from developing small kits to going to build the real 2m size wind turbine to provide energy to the rural regional areas we were working on. In that specific event we were working at The Foundry a nice project and association that we have settled on the north part of GaliZA into the Northwest of Spain.<br />
<br />
During the event many things have been activated between the doers and the visitors; In general It was a wondering experience full of new things to study, learn, doing and understand together. <br />
<br />
We chose this model because It was full of layers of interest on the levels of learning, understanding and making it, here some levels mixed up with layers: <br />
<br />
first to all is one of the ones that is '''open source''' or at least has the option to access the full documentation.<br />
<br />
really '''rich on the pedagogical level''', we were really learning through the complete building of the generator itself, about many topics as :<br />
* electromagnetism<br />
* mathematics<br />
* geometry<br />
* electronics<br />
* AC-DC<br />
* welding<br />
* wood carving<br />
* sculpting and casting pieces<br />
and much more that was reaching through the nice process of reading, learning and building together.<br />
<br />
== Glossary ==<br />
<br />
* '''AC-'''Alternating current as produced by the alternator. All thread - USA word for 'threaded' or 'spun' rod or studding<br />
* '''Brake switch''' - A switch used to short-circuit the wires from the alternator so that it stops.<br />
* '''Catalyst''' - A chemical used to make the polyester resin set solid. Catalyst reacts with 'accelerator' already present in the resin mix. <br />
The heat of reaction sets the polyester.<br />
* '''Cavalier''' - A make of car. The cavalier in the UK is not the same as the Cavalier in the USA but both have useful wheel hubs.<br />
* '''DC - direct current''' with a positive and a negative side, as in battery circuits.<br />
* '''Diameter''' - The distance from one side of a circle to another. The width of a disk right across the middle.<br />
* '''Phase''' - The timing of the cyclical alternation of voltage in a circuit. Different phases will peak at different times.<br />
* '''Polyester''' - A type of resin used in fibreglass work. Also suitable for making castings.<br />
* '''Power''' - the rate of delivery of energy<br />
* '''Rectifier''' - A semiconductor device that turns AC into DC for charging the battery.<br />
* '''Root''' - The widest part of the blade near to the hub at the center of the rotor.<br />
* '''Rotor''' - A rotating part. Magnet rotors are the steel diskscarrying the magnets past the stator. Rotor blades are the 'propeller' <br />
driven by the wind and driving the magnet rotors.<br />
* '''Soldering''' - A method for making electrical connections between wires using a hot 'iron' and coating everything with molten solder.<br />
* '''Drag''' - A force exerted by the wind on an object. Drag is parallel to the wind direction at the object. (see Lift) <br />
* '''Stator''' - An assembly of coils embedded in a slab of resin to form part of the alternator. The magnets induce a voltage in the coils and we can use this to charge a battery.<br />
* '''Drop''' - Used here to describe a certain measurement of the shape of a windmill blade. The 'drop' affects the angle of<br />
the blade to the wind. Styrene monomer - A nasty smelling solvent in the polyester resin mix.<br />
* '''Flux''' - The 'stuff' of magnetism. Similar to 'current' in electricity. It can be visualized as 'lines' coming out of one pole and <br />
returning to the other.<br />
* '''Furling''' - A protective action that reduces exposure to violent winds by facing the blades away from them.<br />
* '''Jig''' - A device used to hold the magnets in place before setting them in resin.<br />
* '''Leading edge''' - The edge of a blade that would strike an object placed in its path as the rotor spins.<br />
* '''Lift''' - A force exerted by the wind on an object. Lift is at right angles to the wind direction at the object. (see Drag)<br />
* '''Mold''' - A shaped container in which resin castings are formed. The mould can be discarded after the casting has set.<br />
* '''Multimeter''' - A versatile electrical test instrument, used to measure voltage, current and other parameters.<br />
* '''Neodymium''' - The name given to a type of permanent magnet containing neodymium, iron and boron. These magnets are very strong and <br />
getting cheaper all the time.<br />
* '''Offset''' - An eccentric position, off centre.<br />
* '''Talcum powder'''- A cheap filler powder used to thicken the resin and slow its reaction (prevent it overheating).<br />
* '''Tail''' - A projecting vane mounted on a boom at the back ofthe windmill used to steer it into or out of the wind automatically.<br />
* '''Tap''' - a tool for making thread inside holes so you can fit a screw into the hole.<br />
* '''Thrust''' - The force of the wind pushing the machine backwards.<br />
* '''Tower''' - The mast supporting the windmill.<br />
* '''Trailing edge''' - The blade edge furthest from the leading edge. The trailing edge is sharpened, so as to release the passing <br />
air without turbulence.<br />
* '''Wedges''' - Tapered pieces of wood used to build up the blade thickness and increase its angle to the wind near the root.<br />
* '''Work-piece''' - The piece of wood or metal being shaped in the workshop.<br />
* '''Yaw bearing''' - the swivel at the top of the tower on which the windmill is mounted. The yaw bearing allows the windmill to face the wind.<br />

== The space == <br />
<br />
=== The Foundry ===<br />
The Foundry is a non-profit organization based in a previously abandoned GaliZA village. It functions both as a residency and as a project space. It subscribes to the ideals of self-organization, and has the following three objectives:<br />
1. Organizing activities in the field of the arts, science and humanities outside of traditional institutions, focusing on critical discourse.<br />
2. Promoting the exchange of ideas and intellectual collaboration outside of the constraints imposed by state and market.<br />
3. Increasing self-sufficiency, sustainability, and an awareness of the environment using appropriate technology and open source as main resources.<br />
Taking into account this context, our aim is to reinforce the capacity to generate networks flowing from rural to urban context supporting non hierarchy and democratic exchanges of knowledge and practices that can enable new and sustainable models within rural contexts. According to that we consider that the new trans-disciplinary creative sectors in which we are entangled can have a huge and positive impact in the creation of this new paradigm. https://bravosfoundry.com/<br />
Aside from that, there is thematic focus on transdisciplinarity, transfeminism and post-humanism. While this focus is not adequately grasped by identity-political categories like race or gender, we hope it leads to the subversion of hegemonic structures inscribed in the binarisms upholding many of these categories. Our interest lies in the development of tools and technologies that subvert contemporary structures of domination, exploitation and marginalization, not in those that reproduce it.<br />
We seek to develop a more sustainable environment by opening up our practices based on a free culture framework, generating networks and interest around them, enabling a flow of exchange of innovation across creative sectors focusing on revaluation of rural contexts and its knowledge heritage.<br />

=== '''Section 2, involves the construction of '''the alternator''' parts using the devices from the section 1.''' ===<br />
<br />
'''Alternator'''<br />
Each magnet rotor is a steel disk with 12 magnets placed on it and set in resin. The magnets are each 50 x 50 x 20 mm, and they only just fit on the disk. The idea is to achieve the maximum amount of flux in a given space.<br />
The turbine runs at 650 rpm for 400W output, so the centrifugal force on the magnets is 60 times the force of gravity. To prevent them flying off, the resin casting needs to be reinforced. Stainless steel wire rope is placed around the outside of the magnets to hold the casting together at high rpm. We use stainless because it is non-magnetic, or at least less magnetic than normal steel wire rope. <br />
<br />
You will wind the coils that produce the output power and cast them in resin to form a stator between the two magnet rotors. Photos of the final pieces here <br />

<br />
[[File:prod05.jpg|200px]] <br />
<br />
Step - Generator, rotor: Preparation of the wheel hub.<br />
<br />
[[File:frame10.jpg|200px]]<br />
<br />
'''The wheel hub'''<br />
<br />
You can find a used car rear wheel hub (Golf, Toyota, etc.) that has a simple way to<br />
attach the axle, or alternatively buy a trailer hubs online new at low cost.<br />
PCD or ‘pitch circle diameter' is the diameter of the circle of the hole pattern in the<br />
hub, and usually this will be 100mm for a car wheel hub, or 4 inches for a trailer hub.<br />
Car hubs may have a brake-drum that you do not need. This can be removed using a<br />
cutting disk on a grinder. The simplest approach is to make four straight cuts around<br />
the four holes in the front, leaving a square surface to which you mount the magnet<br />
rotors. These photos show a golf rear wheel hub – first the brake-drum being cut, and<br />
then the finished hub after cutting off the drum.A typical rear wheel car hub with a <br />
flange on the back end of the stub shaft that can reused to mount it.<br />
Trailer hubs on the other hand are rather basic quality, and the bearings may be too<br />
cheap for long term use, but they are readily available items that can be purchased<br />
online as new. The drawings below (from autow.com) show a typical hub and stub<br />
axle which are bought separately.<br />
You need to be ready to replace the bearings with a named brand (such as SKF). It’s<br />
easy to replace the inner cones and rollers but the outer shells need to be knocked<br />
gently out of the hub with a suitable drift. Keep them straight by tapping evenly on<br />
opposite sides, and take care not to scratch the seating.<br />

Step - Generator, rotor: PreStep<br />
<br />
=== Section 4, involves the craving of the blades and the welding of the base for the turbine generator. ===<br />
<br />
4.1 Making the blades <br />
The drawknife is useful for thicker chunks of wood, and for cutting down into a hollow. <br />
It can make a nice smooth job of the root of the blade, whereas the plane will work better <br />
where you need a very straight finish.<br />
<br />
'''Marking the stations.'''<br />
<br />
Place the blade with its best edge toward you on its upper surface. This will actually<br />
become the back or ‘downwind’ side of the finished blade.<br />
(Most of the front or windward side is to be cut off, so defects on this underneath side<br />
are not important.)<br />
<br />
The root of the blade will be on your right, the tip at the left, 1000 mm from the root<br />
(near the left end).<br />
<br />
Measure from the root, and mark four stations.<br />
Station A at 75mm<br />
Station B at 150 mm<br />
Station C at 500 mm<br />
The Tip at 1000 mm.<br />
<br />
<br />
At each station draw a line right around the workpiece using a square.<br />
<br />
[[File:01tur.jpeg|400px]]<br />
<br />
<br />
'''Tapering the blade'''<br />
The width of the blade tapers down from full size at station C to 55 mm wide at the<br />
tip. Mark the 55 mm tip width, measuring from the leading edge side. Draw a line<br />
though your mark to the trailing edge side at C station and cut off a triangular piece so<br />
as to achieve the correct tapered shape for the blade. Any knots in the triangular<br />
off cut do not matter as this piece is discarded. Try to make this a "square" cut,<br />
perpendicular to the back surface of the blade.<br />
You can do this with a circular saw, or by cross-cutting and shaving as described<br />
above.<br />
<br />
<br />
[[File:02tur.jpeg|400px]]<br />
<br />
'''Marking the leading and trailing edges'''<br />
The next step is to cut the windward face of the blade. This face is defined by the<br />
leading and trailing edge lines of the blade. These lines need to be marked with<br />
reference to the back face of the wood which has been uppermost in the previous<br />
operation.<br />
<br />
Turn the wood over. Start by drawing two diagonal lines between stations A and B<br />
on the front or windward side (see below). One is on the front face and the other on<br />
the trailing edge which is now toward you. <br />
<br />
[[File:03tur.jpeg|400px]]<br />
<br />
<br />
Now draw the leading edge line as shown below, <br />
from station B, down to 16mm(from the back) at station C, then continuing to the tip at<br />
7mm from the back.<br />
<br />
[[File:04tur.jpeg|400px]]<br />
<br />
<br />
(This drawing does not show the extra bit beyond the tip which may remain <br />
in your actual workpiece.)<br />
<br />
Measurements are summarised in this table below. Heights are from the back of the<br />
blade which will then rest on the bench. Remove the wood above this height. "Full"<br />
refers to the full thickness of the original piece of wood you are using.<br />
<br />
<br />
<br />
[[File:05tur.jpeg|400px]]<br />
<br />
<br />
'''The trailing''' <br />
The trailing edge line starts at the bottom of the diagonal line at station B, and <br />
rises to 5mm at C, continuing at 5 mm to the tip. This view below shows the wood <br />
already removed between the two lines to form the windward face of the blade.<br />
<br />
<br />
[[File:06tur.png|400px]]<br />
<br />
<br />
Carve this flat windward face between the 2 lines. Take care that the edges are<br />
straight, following the lines. The best tool to use for finishing the outer part of the<br />
blade is a plane, to give a smooth, straight finish. You may need to work the plane at<br />
45 degrees to the workpiece, sliding partly sideways, to form the hollow shape at<br />
station C.<br />
<br />
This step is completed when you can place a ruler across the face between the leading<br />
and trailing edge lines and there is no ‘hump’ in the middle. Fill any chips or small<br />
hollows with wood filler. If there are any serious errors, or large knots that weaken<br />
the blade then it may have to be discarded.<br />
Check the “drop” using a level as a reference. Clamp the wood so that the root part<br />
sits level, and measure the difference in level between the leading and trailing edges.<br />
The difference or “drop” should be 11 mm at the 500 mm mid-point, and 2 mm at the<br />
tip.<br />

"Pedagoxías do vento e das estrelas. As relacións sociais ás que (nunca estabamos destinados a) sobrevivir, tamén vivimos nos nosos corpos dolorosamente, e Audre Lorde non está aquí para lembrarnos esta lección, salvo na medida en que está presente no vento pedagóxico.<br />
Pero o vento é o noso mestre (74). -Alexis Pauline Gumbs "<br />
<br />
O principal obxectivo deste evento é prototipar un xerador eólico a pequena escala para camiñar xuntos cara á autosuficiencia neste campo.<br />
Temos o pracer de comunicarvos que do 16 ao 23 de outubro Biotranslab de Pin e The Foundry establecen unha colaboración para levar a cabo o evento Eco (i) Logic Queer Energy harvesting. O proxecto é posible grazas ao apoio de GOSH, unha rede para desenvolver e difundir proxectos baseados en hardware de código aberto para a ciencia.<br />
<br />
EcoLoxicas Queer para a captación de enerxía eolica. <br />
O evento ten como obxectivo abordar a falta de mulleres, queer, trans e diversidade nos ámbitos tecnolóxicos en xeral e do hacking máis concretamente. Pero aínda máis, pretende crear unha comunidade que avalía criticamente as narrativas hexemónicas arredor das tecnoloxías, os aspectos de modernidade dos seus supostos occidentais subliñados e as súas inflexións capitalistas inherentes, entre outros.<br />
O obxectivo principal do evento é desenvolver kits que se centren na interacción co medio natural no ámbito da enerxía.. o obxectivo principal pasa pola captación de enerxía do medio natural, a través dos aeroxeradores. Estes kits de enerxía serán escalables e poderán utilizarse tanto como material pedagóxico como para instalar centrais eléctricas específicas do sitio en diferentes sitios tamén. Este traballo ten un compoñente contrainfraestrutural: unha posible consecuencia sería capacitar ás persoas para xerar a súa propia enerxía en lugar de depender de grandes empresas e moitas veces extractivas.<br />

''Pedagogies of the Wind and Stars. The social relations that we (were never meant to) survive, also live in our bodies painfully, and Audre Lorde is not here to remind us of this lesson herself, except in as much that she is present in the pedagogical wind. But wind is our teacher (74). -Alexis Pauline Gumbs'' from the book Mapping Queer Space(s) of Praxis and Pedagogy <br />
Editors: Elizabeth McNeil, James E. Wermers, Joshua O. Lunn'' <br />
<br />
We have the pleasure to communicate you that from 16 to 29 of October Pin Biotranslab, Casa do Río e The Foundry establishes a collaboration to run the event Eco (i) Logic Queer Energy harvesting. The project is possible thanks to the support of GOSH, an network for develop and disseminate projects based on Open Source hardware for Science.<br />
<br />
'''Eco (i) Logic Queer Energy harvesting''' <br />
The event aims at addressing the lack of women, queer, trans and diversity in technological fields in general and hacking more specifically. But even more so, it aims at creating a community that critically assesses the hegemonic narratives around technologies, the modernity aspects of its underlining Western assumptions and its inherent capitalist inflections, among others.<br />
The main purpose of the event is to develop kits that focus on interacting with the natural environment on the field of energy.. the main objective lies on harvesting energy of the natural environment, through wind turbines. These power kits will be scalable and can be used both as pedagogical material and to set up site-specific power plants in different sites as well. There is a counter-infrastructural component to this work: one possible consequence would be to empower people to generate their own energy instead of relying on large and often extractive companies.<br />
<br />
== Introduction and values of the process ==<br />
<br />
Here starts the documentation of the long process of the prototyping the Hugh Piggott The Piggott Turbine – Wind Empowerment model of an Open source wind turbine. We were changing a bit the goals of the event from developing small kits to going to build the real 2m size wind turbine to provide energy to the rural regional areas we were working on. In that specific event we were working at The Foundry a nice project and association that we have settled on the north part of GaliZA into the Northwest of Spain.<br />
<br />
During the event many things have been activated between the doers and the visitors; In general It was a wondering experience full of new things to study, learn, doing and understand together. <br />
<br />
We chose this model because It was full of layers of interest on the levels of learning, understanding and making it, here some levels mixed up with layers: <br />
<br />
first to all is one of the ones that is '''open source''' or at least has the option to access the full documentation.<br />
<br />
really '''rich on the pedagogical level''', we were really learning through the complete building of the generator itself, about many topics as :<br />
* electromagnetism<br />
* mathematics<br />
* geometry<br />
* electronics<br />
* AC-DC<br />
* welding<br />
* wood carving<br />
* sculpting and casting pieces<br />
and much more that was reaching through the nice process of reading, learning and building together.<br />
<br />
== Glossary ==<br />
<br />
* '''AC-'''Alternating current as produced by the alternator. All thread - USA word for 'threaded' or 'spun' rod or studding<br />
* '''Brake switch''' - A switch used to short-circuit the wires from the alternator so that it stops.<br />
* '''Catalyst''' - A chemical used to make the polyester resin set solid. Catalyst reacts with 'accelerator' already present in the resin mix. <br />
The heat of reaction sets the polyester.<br />
* '''Cavalier''' - A make of car. The cavalier in the UK is not the same as the Cavalier in the USA but both have useful wheel hubs.<br />
* '''DC - direct current''' with a positive and a negative side, as in battery circuits.<br />
* '''Diameter''' - The distance from one side of a circle to another. The width of a disk right across the middle.<br />
* '''Phase''' - The timing of the cyclical alternation of voltage in a circuit. Different phases will peak at different times.<br />
* '''Polyester''' - A type of resin used in fibreglass work. Also suitable for making castings.<br />
* '''Power''' - the rate of delivery of energy<br />
* '''Rectifier''' - A semiconductor device that turns AC into DC for charging the battery.<br />
* '''Root''' - The widest part of the blade near to the hub at the center of the rotor.<br />
* '''Rotor''' - A rotating part. Magnet rotors are the steel diskscarrying the magnets past the stator. Rotor blades are the 'propeller' <br />
driven by the wind and driving the magnet rotors.<br />
* '''Soldering''' - A method for making electrical connections between wires using a hot 'iron' and coating everything with molten solder.<br />
* '''Drag''' - A force exerted by the wind on an object. Drag is parallel to the wind direction at the object. (see Lift) <br />
* '''Stator''' - An assembly of coils embedded in a slab of resin to form part of the alternator. The magnets induce a voltage in the coils and we can use this to charge a battery.<br />
* '''Drop''' - Used here to describe a certain measurement of the shape of a windmill blade. The 'drop' affects the angle of<br />
the blade to the wind. Styrene monomer - A nasty smelling solvent in the polyester resin mix.<br />
* '''Flux''' - The 'stuff' of magnetism. Similar to 'current' in electricity. It can be visualized as 'lines' coming out of one pole and <br />
returning to the other.<br />
* '''Furling''' - A protective action that reduces exposure to violent winds by facing the blades away from them.<br />
* '''Jig''' - A device used to hold the magnets in place before setting them in resin.<br />
* '''Leading edge''' - The edge of a blade that would strike an object placed in its path as the rotor spins.<br />
* '''Lift''' - A force exerted by the wind on an object. Lift is at right angles to the wind direction at the object. (see Drag)<br />
* '''Mold''' - A shaped container in which resin castings are formed. The mould can be discarded after the casting has set.<br />
* '''Multimeter''' - A versatile electrical test instrument, used to measure voltage, current and other parameters.<br />
* '''Neodymium''' - The name given to a type of permanent magnet containing neodymium, iron and boron. These magnets are very strong and <br />
getting cheaper all the time.<br />
* '''Offset''' - An eccentric position, off centre.<br />
* '''Talcum powder'''- A cheap filler powder used to thicken the resin and slow its reaction (prevent it overheating).<br />
* '''Tail''' - A projecting vane mounted on a boom at the back ofthe windmill used to steer it into or out of the wind automatically.<br />
* '''Tap''' - a tool for making thread inside holes so you can fit a screw into the hole.<br />
* '''Thrust''' - The force of the wind pushing the machine backwards.<br />
* '''Tower''' - The mast supporting the windmill.<br />
* '''Trailing edge''' - The blade edge furthest from the leading edge. The trailing edge is sharpened, so as to release the passing <br />
air without turbulence.<br />
* '''Wedges''' - Tapered pieces of wood used to build up the blade thickness and increase its angle to the wind near the root.<br />
* '''Work-piece''' - The piece of wood or metal being shaped in the workshop.<br />
* '''Yaw bearing''' - the swivel at the top of the tower on which the windmill is mounted. The yaw bearing allows the windmill to face the wind.<br />

== The space == <br />
<br />
=== The Foundry ===<br />
The Foundry is a non-profit organization based in a previously abandoned GaliZA village. It functions both as a residency and as a project space. It subscribes to the ideals of self-organization, and has the following three objectives:<br />
1. Organizing activities in the field of the arts, science and humanities outside of traditional institutions, focusing on critical discourse.<br />
2. Promoting the exchange of ideas and intellectual collaboration outside of the constraints imposed by state and market.<br />
3. Increasing self-sufficiency, sustainability, and an awareness of the environment using appropriate technology and open source as main resources.<br />
Taking into account this context, our aim is to reinforce the capacity to generate networks flowing from rural to urban context supporting non hierarchy and democratic exchanges of knowledge and practices that can enable new and sustainable models within rural contexts. According to that we consider that the new trans-disciplinary creative sectors in which we are entangled can have a huge and positive impact in the creation of this new paradigm. https://bravosfoundry.com/<br />
Aside from that, there is thematic focus on transdisciplinarity, transfeminism and post-humanism. While this focus is not adequately grasped by identity-political categories like race or gender, we hope it leads to the subversion of hegemonic structures inscribed in the binarisms upholding many of these categories. Our interest lies in the development of tools and technologies that subvert contemporary structures of domination, exploitation and marginalization, not in those that reproduce it.<br />
We seek to develop a more sustainable environment by opening up our practices based on a free culture framework, generating networks and interest around them, enabling a flow of exchange of innovation across creative sectors focusing on revaluation of rural contexts and its knowledge heritage.<br />

=== '''Section 2, involves the construction of '''the alternator''' parts using the devices from the section 1.''' ===<br />
<br />
'''Alternator'''<br />
Each magnet rotor is a steel disk with 12 magnets placed on it and set in resin. The magnets are each 50 x 50 x 20 mm, and they only just fit on the disk. The idea is to achieve the maximum amount of flux in a given space.<br />
The turbine runs at 650 rpm for 400W output, so the centrifugal force on the magnets is 60 times the force of gravity. To prevent them flying off, the resin casting needs to be reinforced. Stainless steel wire rope is placed around the outside of the magnets to hold the casting together at high rpm. We use stainless because it is non-magnetic, or at least less magnetic than normal steel wire rope. <br />
<br />
You will wind the coils that produce the output power and cast them in resin to form a stator between the two magnet rotors. Photos of the final pieces here <br />

<br />
[[File:prod05.jpg|200px]] <br />
<br />
Step - Generator, rotor: Preparation of the wheel hub.<br />
<br />
[[File:frame10.jpg|200px]]<br />
<br />
'''The wheel hub'''<br />
<br />
You can find a used car rear wheel hub (Golf, Toyota, etc.) that has a simple way to<br />
attach the axle, or alternatively buy a trailer hubs online new at low cost.<br />
PCD or ‘pitch circle diameter' is the diameter of the circle of the hole pattern in the<br />
hub, and usually this will be 100mm for a car wheel hub, or 4 inches for a trailer hub.<br />
Car hubs may have a brake-drum that you do not need. This can be removed using a<br />
cutting disk on a grinder. The simplest approach is to make four straight cuts around<br />
the four holes in the front, leaving a square surface to which you mount the magnet<br />
rotors. These photos show a golf rear wheel hub – first the brake-drum being cut, and<br />
then the finished hub after cutting off the drum.A typical rear wheel car hub with a <br />
flange on the back end of the stub shaft that can reused to mount it.<br />
Trailer hubs on the other hand are rather basic quality, and the bearings may be too<br />
cheap for long term use, but they are readily available items that can be purchased<br />
online as new. The drawings below (from autow.com) show a typical hub and stub<br />
axle which are bought separately.<br />
You need to be ready to replace the bearings with a named brand (such as SKF). It’s<br />
easy to replace the inner cones and rollers but the outer shells need to be knocked<br />
gently out of the hub with a suitable drift. Keep them straight by tapping evenly on<br />
opposite sides, and take care not to scratch the seating.<br />

Step - Generator, rotor: PreStep<br />
<br />
=== Section 4, involves the craving of the blades and the welding of the base for the turbine generator. ===<br />
<br />
4.1 Making the blades <br />
The drawknife is useful for thicker chunks of wood, and for cutting down into a hollow. <br />
It can make a nice smooth job of the root of the blade, whereas the plane will work better <br />
where you need a very straight finish.<br />
<br />
'''Marking the stations.'''<br />
<br />
Place the blade with its best edge toward you on its upper surface. This will actually<br />
become the back or ‘downwind’ side of the finished blade.<br />
(Most of the front or windward side is to be cut off, so defects on this underneath side<br />
are not important.)<br />
<br />
The root of the blade will be on your right, the tip at the left, 1000 mm from the root<br />
(near the left end).<br />
<br />
Measure from the root, and mark four stations.<br />
Station A at 75mm<br />
Station B at 150 mm<br />
Station C at 500 mm<br />
The Tip at 1000 mm.<br />
<br />
<br />
At each station draw a line right around the workpiece using a square.<br />
<br />
[[File:01tur.jpeg|400px]]<br />
<br />
<br />
'''Tapering the blade'''<br />
The width of the blade tapers down from full size at station C to 55 mm wide at the<br />
tip. Mark the 55 mm tip width, measuring from the leading edge side. Draw a line<br />
though your mark to the trailing edge side at C station and cut off a triangular piece so<br />
as to achieve the correct tapered shape for the blade. Any knots in the triangular<br />
off cut do not matter as this piece is discarded. Try to make this a "square" cut,<br />
perpendicular to the back surface of the blade.<br />
You can do this with a circular saw, or by cross-cutting and shaving as described<br />
above.<br />
<br />
<br />
[[File:02tur.jpeg|400px]]<br />
<br />
'''Marking the leading and trailing edges'''<br />
The next step is to cut the windward face of the blade. This face is defined by the<br />
leading and trailing edge lines of the blade. These lines need to be marked with<br />
reference to the back face of the wood which has been uppermost in the previous<br />
operation.<br />
<br />
Turn the wood over. Start by drawing two diagonal lines between stations A and B<br />
on the front or windward side (see below). One is on the front face and the other on<br />
the trailing edge which is now toward you. <br />
<br />
[[File:03tur.jpeg|400px]]<br />
<br />
<br />
Now draw the leading edge line as shown below, <br />
from station B, down to 16mm(from the back) at station C, then continuing to the tip at<br />
7mm from the back.<br />
<br />
[[File:04tur.jpeg|400px]]<br />
<br />
<br />
(This drawing does not show the extra bit beyond the tip which may remain <br />
in your actual workpiece.)<br />
<br />
Measurements are summarised in this table below. Heights are from the back of the<br />
blade which will then rest on the bench. Remove the wood above this height. "Full"<br />
refers to the full thickness of the original piece of wood you are using.<br />
<br />
<br />
<br />
[[File:05tur.jpeg|400px]]<br />
<br />
<br />
'''The trailing''' <br />
The trailing edge line starts at the bottom of the diagonal line at station B, and <br />
rises to 5mm at C, continuing at 5 mm to the tip. This view below shows the wood <br />
already removed between the two lines to form the windward face of the blade.<br />
<br />
<br />
[[File:06tur.png|400px]]<br />
<br />
<br />
Carve this flat windward face between the 2 lines. Take care that the edges are<br />
straight, following the lines. The best tool to use for finishing the outer part of the<br />
blade is a plane, to give a smooth, straight finish. You may need to work the plane at<br />
45 degrees to the workpiece, sliding partly sideways, to form the hollow shape at<br />
station C.<br />
<br />
This step is completed when you can place a ruler across the face between the leading<br />
and trailing edge lines and there is no ‘hump’ in the middle. Fill any chips or small<br />
hollows with wood filler. If there are any serious errors, or large knots that weaken<br />
the blade then it may have to be discarded.<br />
Check the “drop” using a level as a reference. Clamp the wood so that the root part<br />
sits level, and measure the difference in level between the leading and trailing edges.<br />
The difference or “drop” should be 11 mm at the 500 mm mid-point, and 2 mm at the<br />
tip.<br />

"Pedagoxías do vento e das estrelas. As relacións sociais ás que (nunca estabamos destinados a) sobrevivir, tamén vivimos nos nosos corpos dolorosamente, e Audre Lorde non está aquí para lembrarnos esta lección, salvo na medida en que está presente no vento pedagóxico.<br />
Pero o vento é o noso mestre (74). -Alexis Pauline Gumbs "<br />
<br />
O principal obxectivo deste evento é prototipar un xerador eólico a pequena escala para camiñar xuntos cara á autosuficiencia neste campo.<br />
Temos o pracer de comunicarvos que do 16 ao 23 de outubro Biotranslab de Pin e The Foundry establecen unha colaboración para levar a cabo o evento Eco (i) Logic Queer Energy harvesting. O proxecto é posible grazas ao apoio de GOSH, unha rede para desenvolver e difundir proxectos baseados en hardware de código aberto para a ciencia.<br />
<br />
EcoLoxicas Queer para a captación de enerxía eolica. <br />
O evento ten como obxectivo abordar a falta de mulleres, queer, trans e diversidade nos ámbitos tecnolóxicos en xeral e do hacking máis concretamente. Pero aínda máis, pretende crear unha comunidade que avalía criticamente as narrativas hexemónicas arredor das tecnoloxías, os aspectos de modernidade dos seus supostos occidentais subliñados e as súas inflexións capitalistas inherentes, entre outros.<br />
O obxectivo principal do evento é desenvolver kits que se centren na interacción co medio natural no ámbito da enerxía.. o obxectivo principal pasa pola captación de enerxía do medio natural, a través dos aeroxeradores. Estes kits de enerxía serán escalables e poderán utilizarse tanto como material pedagóxico como para instalar centrais eléctricas específicas do sitio en diferentes sitios tamén. Este traballo ten un compoñente contrainfraestrutural: unha posible consecuencia sería capacitar ás persoas para xerar a súa propia enerxía en lugar de depender de grandes empresas e moitas veces extractivas.<br />

''Pedagogies of the Wind and Stars. The social relations that we (were never meant to) survive, also live in our bodies painfully, and Audre Lorde is not here to remind us of this lesson herself, except in as much that she is present in the pedagogical wind. But wind is our teacher (74). -Alexis Pauline Gumbs'' from the book Mapping Queer Space(s) of Praxis and Pedagogy <br />
Editors: Elizabeth McNeil, James E. Wermers, Joshua O. Lunn'' <br />
<br />
We have the pleasure to communicate you that from 16 to 29 of October Pin Biotranslab, Casa do Río e The Foundry establishes a collaboration to run the event Eco (i) Logic Queer Energy harvesting. The project is possible thanks to the support of GOSH, an network for develop and disseminate projects based on Open Source hardware for Science.<br />
<br />
'''Eco (i) Logic Queer Energy harvesting''' <br />
The event aims at addressing the lack of women, queer, trans and diversity in technological fields in general and hacking more specifically. But even more so, it aims at creating a community that critically assesses the hegemonic narratives around technologies, the modernity aspects of its underlining Western assumptions and its inherent capitalist inflections, among others.<br />
The main purpose of the event is to develop kits that focus on interacting with the natural environment on the field of energy.. the main objective lies on harvesting energy of the natural environment, through wind turbines. These power kits will be scalable and can be used both as pedagogical material and to set up site-specific power plants in different sites as well. There is a counter-infrastructural component to this work: one possible consequence would be to empower people to generate their own energy instead of relying on large and often extractive companies.<br />
<br />
== Introduction and values of the process ==<br />
<br />
Here starts the documentation of the long process of the prototyping the Hugh Piggott The Piggott Turbine – Wind Empowerment model of an Open source wind turbine. We were changing a bit the goals of the event from developing small kits to going to build the real 2m size wind turbine to provide energy to the rural regional areas we were working on. In that specific event we were working at The Foundry a nice project and association that we have settled on the north part of GaliZA into the Northwest of Spain.<br />
<br />
During the event many things have been activated between the doers and the visitors; In general It was a wondering experience full of new things to study, learn, doing and understand together. <br />
<br />
We chose this model because It was full of layers of interest on the levels of learning, understanding and making it, here some levels mixed up with layers: <br />
<br />
first to all is one of the ones that is '''open source''' or at least has the option to access the full documentation.<br />
<br />
really '''rich on the pedagogical level''', we were really learning through the complete building of the generator itself, about many topics as :<br />
* electromagnetism<br />
* mathematics<br />
* geometry<br />
* electronics<br />
* AC-DC<br />
* welding<br />
* wood carving<br />
* sculpting and casting pieces<br />
and much more that was reaching through the nice process of reading, learning and building together.<br />
<br />
== Glossary ==<br />
<br />
* '''AC-'''Alternating current as produced by the alternator. All thread - USA word for 'threaded' or 'spun' rod or studding<br />
* '''Brake switch''' - A switch used to short-circuit the wires from the alternator so that it stops.<br />
* '''Catalyst''' - A chemical used to make the polyester resin set solid. Catalyst reacts with 'accelerator' already present in the resin mix. <br />
The heat of reaction sets the polyester.<br />
* '''Cavalier''' - A make of car. The cavalier in the UK is not the same as the Cavalier in the USA but both have useful wheel hubs.<br />
* '''DC - direct current''' with a positive and a negative side, as in battery circuits.<br />
* '''Diameter''' - The distance from one side of a circle to another. The width of a disk right across the middle.<br />
* '''Phase''' - The timing of the cyclical alternation of voltage in a circuit. Different phases will peak at different times.<br />
* '''Polyester''' - A type of resin used in fibreglass work. Also suitable for making castings.<br />
* '''Power''' - the rate of delivery of energy<br />
* '''Rectifier''' - A semiconductor device that turns AC into DC for charging the battery.<br />
* '''Root''' - The widest part of the blade near to the hub at the center of the rotor.<br />
* '''Rotor''' - A rotating part. Magnet rotors are the steel diskscarrying the magnets past the stator. Rotor blades are the 'propeller' <br />
driven by the wind and driving the magnet rotors.<br />
* '''Soldering''' - A method for making electrical connections between wires using a hot 'iron' and coating everything with molten solder.<br />
* '''Drag''' - A force exerted by the wind on an object. Drag is parallel to the wind direction at the object. (see Lift) <br />
* '''Stator''' - An assembly of coils embedded in a slab of resin to form part of the alternator. The magnets induce a voltage in the coils and we can use this to charge a battery.<br />
* '''Drop''' - Used here to describe a certain measurement of the shape of a windmill blade. The 'drop' affects the angle of<br />
the blade to the wind. Styrene monomer - A nasty smelling solvent in the polyester resin mix.<br />
* '''Flux''' - The 'stuff' of magnetism. Similar to 'current' in electricity. It can be visualized as 'lines' coming out of one pole and <br />
returning to the other.<br />
* '''Furling''' - A protective action that reduces exposure to violent winds by facing the blades away from them.<br />
* '''Jig''' - A device used to hold the magnets in place before setting them in resin.<br />
* '''Leading edge''' - The edge of a blade that would strike an object placed in its path as the rotor spins.<br />
* '''Lift''' - A force exerted by the wind on an object. Lift is at right angles to the wind direction at the object. (see Drag)<br />
* '''Mold''' - A shaped container in which resin castings are formed. The mould can be discarded after the casting has set.<br />
* '''Multimeter''' - A versatile electrical test instrument, used to measure voltage, current and other parameters.<br />
* '''Neodymium''' - The name given to a type of permanent magnet containing neodymium, iron and boron. These magnets are very strong and <br />
getting cheaper all the time.<br />
* '''Offset''' - An eccentric position, off centre.<br />
* '''Talcum powder'''- A cheap filler powder used to thicken the resin and slow its reaction (prevent it overheating).<br />
* '''Tail''' - A projecting vane mounted on a boom at the back ofthe windmill used to steer it into or out of the wind automatically.<br />
* '''Tap''' - a tool for making thread inside holes so you can fit a screw into the hole.<br />
* '''Thrust''' - The force of the wind pushing the machine backwards.<br />
* '''Tower''' - The mast supporting the windmill.<br />
* '''Trailing edge''' - The blade edge furthest from the leading edge. The trailing edge is sharpened, so as to release the passing <br />
air without turbulence.<br />
* '''Wedges''' - Tapered pieces of wood used to build up the blade thickness and increase its angle to the wind near the root.<br />
* '''Work-piece''' - The piece of wood or metal being shaped in the workshop.<br />
* '''Yaw bearing''' - the swivel at the top of the tower on which the windmill is mounted. The yaw bearing allows the windmill to face the wind.<br />

== The space == <br />
<br />
=== The Foundry ===<br />
The Foundry is a non-profit organization based in a previously abandoned GaliZA village. It functions both as a residency and as a project space. It subscribes to the ideals of self-organization, and has the following three objectives:<br />
1. Organizing activities in the field of the arts, science and humanities outside of traditional institutions, focusing on critical discourse.<br />
2. Promoting the exchange of ideas and intellectual collaboration outside of the constraints imposed by state and market.<br />
3. Increasing self-sufficiency, sustainability, and an awareness of the environment using appropriate technology and open source as main resources.<br />
Taking into account this context, our aim is to reinforce the capacity to generate networks flowing from rural to urban context supporting non hierarchy and democratic exchanges of knowledge and practices that can enable new and sustainable models within rural contexts. According to that we consider that the new trans-disciplinary creative sectors in which we are entangled can have a huge and positive impact in the creation of this new paradigm. https://bravosfoundry.com/<br />
Aside from that, there is thematic focus on transdisciplinarity, transfeminism and post-humanism. While this focus is not adequately grasped by identity-political categories like race or gender, we hope it leads to the subversion of hegemonic structures inscribed in the binarisms upholding many of these categories. Our interest lies in the development of tools and technologies that subvert contemporary structures of domination, exploitation and marginalization, not in those that reproduce it.<br />
We seek to develop a more sustainable environment by opening up our practices based on a free culture framework, generating networks and interest around them, enabling a flow of exchange of innovation across creative sectors focusing on revaluation of rural contexts and its knowledge heritage.<br />

=== '''Section 2, involves the construction of '''the alternator''' parts using the devices from the section 1.''' ===<br />
<br />
'''Alternator'''<br />
Each magnet rotor is a steel disk with 12 magnets placed on it and set in resin. The magnets are each 50 x 50 x 20 mm, and they only just fit on the disk. The idea is to achieve the maximum amount of flux in a given space.<br />
The turbine runs at 650 rpm for 400W output, so the centrifugal force on the magnets is 60 times the force of gravity. To prevent them flying off, the resin casting needs to be reinforced. Stainless steel wire rope is placed around the outside of the magnets to hold the casting together at high rpm. We use stainless because it is non-magnetic, or at least less magnetic than normal steel wire rope. <br />
<br />
You will wind the coils that produce the output power and cast them in resin to form a stator between the two magnet rotors. Photos of the final pieces here <br />

[[File:prod05.jpg|200px]] <br />
<br />
Step - Generator, rotor: Preparation of the wheel hub.<br />
<br />
[[File:frame10.jpg|200px]]<br />
<br />
'''The wheel hub'''<br />
<br />
You can find a used car rear wheel hub (Golf, Toyota, etc.) that has a simple way to<br />
attach the axle, or alternatively buy a trailer hubs online new at low cost.<br />
PCD or ‘pitch circle diameter' is the diameter of the circle of the hole pattern in the<br />
hub, and usually this will be 100mm for a car wheel hub, or 4 inches for a trailer hub.<br />
Car hubs may have a brake-drum that you do not need. This can be removed using a<br />
cutting disk on a grinder. The simplest approach is to make four straight cuts around<br />
the four holes in the front, leaving a square surface to which you mount the magnet<br />
rotors. These photos show a golf rear wheel hub – first the brake-drum being cut, and<br />
then the finished hub after cutting off the drum.A typical rear wheel car hub with a <br />
flange on the back end of the stub shaft that can reused to mount it.<br />
Trailer hubs on the other hand are rather basic quality, and the bearings may be too<br />
cheap for long term use, but they are readily available items that can be purchased<br />
online as new. The drawings below (from autow.com) show a typical hub and stub<br />
axle which are bought separately.<br />
You need to be ready to replace the bearings with a named brand (such as SKF). It’s<br />
easy to replace the inner cones and rollers but the outer shells need to be knocked<br />
gently out of the hub with a suitable drift. Keep them straight by tapping evenly on<br />
opposite sides, and take care not to scratch the seating.<br />

Step - Generator, rotor: PreStep<br />
<br />
=== Section 4, involves the craving of the blades and the welding of the base for the turbine generator. ===<br />
<br />
4.1 Making the blades <br />
The drawknife is useful for thicker chunks of wood, and for cutting down into a hollow. <br />
It can make a nice smooth job of the root of the blade, whereas the plane will work better <br />
where you need a very straight finish.<br />
<br />
'''Marking the stations.'''<br />
<br />
Place the blade with its best edge toward you on its upper surface. This will actually<br />
become the back or ‘downwind’ side of the finished blade.<br />
(Most of the front or windward side is to be cut off, so defects on this underneath side<br />
are not important.)<br />
<br />
The root of the blade will be on your right, the tip at the left, 1000 mm from the root<br />
(near the left end).<br />
<br />
Measure from the root, and mark four stations.<br />
Station A at 75mm<br />
Station B at 150 mm<br />
Station C at 500 mm<br />
The Tip at 1000 mm.<br />
<br />
<br />
At each station draw a line right around the workpiece using a square.<br />
<br />
[[File:01tur.jpeg|400px]]<br />
<br />
<br />
'''Tapering the blade'''<br />
The width of the blade tapers down from full size at station C to 55 mm wide at the<br />
tip. Mark the 55 mm tip width, measuring from the leading edge side. Draw a line<br />
though your mark to the trailing edge side at C station and cut off a triangular piece so<br />
as to achieve the correct tapered shape for the blade. Any knots in the triangular<br />
off cut do not matter as this piece is discarded. Try to make this a "square" cut,<br />
perpendicular to the back surface of the blade.<br />
You can do this with a circular saw, or by cross-cutting and shaving as described<br />
above.<br />
<br />
<br />
[[File:02tur.jpeg|400px]]<br />
<br />
'''Marking the leading and trailing edges'''<br />
The next step is to cut the windward face of the blade. This face is defined by the<br />
leading and trailing edge lines of the blade. These lines need to be marked with<br />
reference to the back face of the wood which has been uppermost in the previous<br />
operation.<br />
<br />
Turn the wood over. Start by drawing two diagonal lines between stations A and B<br />
on the front or windward side (see below). One is on the front face and the other on<br />
the trailing edge which is now toward you. <br />
<br />
[[File:03tur.jpeg|400px]]<br />
<br />
<br />
Now draw the leading edge line as shown below, <br />
from station B, down to 16mm(from the back) at station C, then continuing to the tip at<br />
7mm from the back.<br />
<br />
[[File:04tur.jpeg|400px]]<br />
<br />
<br />
(This drawing does not show the extra bit beyond the tip which may remain <br />
in your actual workpiece.)<br />
<br />
Measurements are summarised in this table below. Heights are from the back of the<br />
blade which will then rest on the bench. Remove the wood above this height. "Full"<br />
refers to the full thickness of the original piece of wood you are using.<br />
<br />
<br />
<br />
[[File:05tur.jpeg|400px]]<br />
<br />
<br />
'''The trailing''' <br />
The trailing edge line starts at the bottom of the diagonal line at station B, and <br />
rises to 5mm at C, continuing at 5 mm to the tip. This view below shows the wood <br />
already removed between the two lines to form the windward face of the blade.<br />
<br />
<br />
[[File:06tur.png|400px]]<br />
<br />
<br />
Carve this flat windward face between the 2 lines. Take care that the edges are<br />
straight, following the lines. The best tool to use for finishing the outer part of the<br />
blade is a plane, to give a smooth, straight finish. You may need to work the plane at<br />
45 degrees to the workpiece, sliding partly sideways, to form the hollow shape at<br />
station C.<br />
<br />
This step is completed when you can place a ruler across the face between the leading<br />
and trailing edge lines and there is no ‘hump’ in the middle. Fill any chips or small<br />
hollows with wood filler. If there are any serious errors, or large knots that weaken<br />
the blade then it may have to be discarded.<br />
Check the “drop” using a level as a reference. Clamp the wood so that the root part<br />
sits level, and measure the difference in level between the leading and trailing edges.<br />
The difference or “drop” should be 11 mm at the 500 mm mid-point, and 2 mm at the<br />
tip.<br />

"Pedagoxías do vento e das estrelas. As relacións sociais ás que (nunca estabamos destinados a) sobrevivir, tamén vivimos nos nosos corpos dolorosamente, e Audre Lorde non está aquí para lembrarnos esta lección, salvo na medida en que está presente no vento pedagóxico.<br />
Pero o vento é o noso mestre (74). -Alexis Pauline Gumbs "<br />
<br />
O principal obxectivo deste evento é prototipar un xerador eólico a pequena escala para camiñar xuntos cara á autosuficiencia neste campo.<br />
Temos o pracer de comunicarvos que do 16 ao 23 de outubro Biotranslab de Pin e The Foundry establecen unha colaboración para levar a cabo o evento Eco (i) Logic Queer Energy harvesting. O proxecto é posible grazas ao apoio de GOSH, unha rede para desenvolver e difundir proxectos baseados en hardware de código aberto para a ciencia.<br />
<br />
EcoLoxicas Queer para a captación de enerxía eolica. <br />
O evento ten como obxectivo abordar a falta de mulleres, queer, trans e diversidade nos ámbitos tecnolóxicos en xeral e do hacking máis concretamente. Pero aínda máis, pretende crear unha comunidade que avalía criticamente as narrativas hexemónicas arredor das tecnoloxías, os aspectos de modernidade dos seus supostos occidentais subliñados e as súas inflexións capitalistas inherentes, entre outros.<br />
O obxectivo principal do evento é desenvolver kits que se centren na interacción co medio natural no ámbito da enerxía.. o obxectivo principal pasa pola captación de enerxía do medio natural, a través dos aeroxeradores. Estes kits de enerxía serán escalables e poderán utilizarse tanto como material pedagóxico como para instalar centrais eléctricas específicas do sitio en diferentes sitios tamén. Este traballo ten un compoñente contrainfraestrutural: unha posible consecuencia sería capacitar ás persoas para xerar a súa propia enerxía en lugar de depender de grandes empresas e moitas veces extractivas.<br />

''Pedagogies of the Wind and Stars. The social relations that we (were never meant to) survive, also live in our bodies painfully, and Audre Lorde is not here to remind us of this lesson herself, except in as much that she is present in the pedagogical wind. But wind is our teacher (74). -Alexis Pauline Gumbs'' from the book Mapping Queer Space(s) of Praxis and Pedagogy <br />
Editors: Elizabeth McNeil, James E. Wermers, Joshua O. Lunn'' <br />
<br />
We have the pleasure to communicate you that from 16 to 29 of October Pin Biotranslab, Casa do Río e The Foundry establishes a collaboration to run the event Eco (i) Logic Queer Energy harvesting. The project is possible thanks to the support of GOSH, an network for develop and disseminate projects based on Open Source hardware for Science.<br />
<br />
'''Eco (i) Logic Queer Energy harvesting''' <br />
The event aims at addressing the lack of women, queer, trans and diversity in technological fields in general and hacking more specifically. But even more so, it aims at creating a community that critically assesses the hegemonic narratives around technologies, the modernity aspects of its underlining Western assumptions and its inherent capitalist inflections, among others.<br />
The main purpose of the event is to develop kits that focus on interacting with the natural environment on the field of energy.. the main objective lies on harvesting energy of the natural environment, through wind turbines. These power kits will be scalable and can be used both as pedagogical material and to set up site-specific power plants in different sites as well. There is a counter-infrastructural component to this work: one possible consequence would be to empower people to generate their own energy instead of relying on large and often extractive companies.<br />
<br />
== Introduction and values of the process ==<br />
<br />
Here starts the documentation of the long process of the prototyping the Hugh Piggott The Piggott Turbine – Wind Empowerment model of an Open source wind turbine. We were changing a bit the goals of the event from developing small kits to going to build the real 2m size wind turbine to provide energy to the rural regional areas we were working on. In that specific event we were working at The Foundry a nice project and association that we have settled on the north part of GaliZA into the Northwest of Spain.<br />
<br />
During the event many things have been activated between the doers and the visitors; In general It was a wondering experience full of new things to study, learn, doing and understand together. <br />
<br />
We chose this model because It was full of layers of interest on the levels of learning, understanding and making it, here some levels mixed up with layers: <br />
<br />
first to all is one of the ones that is '''open source''' or at least has the option to access the full documentation.<br />
<br />
really '''rich on the pedagogical level''', we were really learning through the complete building of the generator itself, about many topics as :<br />
* electromagnetism<br />
* mathematics<br />
* geometry<br />
* electronics<br />
* AC-DC<br />
* welding<br />
* wood carving<br />
* sculpting and casting pieces<br />
and much more that was reaching through the nice process of reading, learning and building together.<br />
<br />
== Glossary ==<br />
<br />
* '''AC-'''Alternating current as produced by the alternator. All thread - USA word for 'threaded' or 'spun' rod or studding<br />
* '''Brake switch''' - A switch used to short-circuit the wires from the alternator so that it stops.<br />
* '''Catalyst''' - A chemical used to make the polyester resin set solid. Catalyst reacts with 'accelerator' already present in the resin mix. <br />
The heat of reaction sets the polyester.<br />
* '''Cavalier''' - A make of car. The cavalier in the UK is not the same as the Cavalier in the USA but both have useful wheel hubs.<br />
* '''DC - direct current''' with a positive and a negative side, as in battery circuits.<br />
* '''Diameter''' - The distance from one side of a circle to another. The width of a disk right across the middle.<br />
* '''Phase''' - The timing of the cyclical alternation of voltage in a circuit. Different phases will peak at different times.<br />
* '''Polyester''' - A type of resin used in fibreglass work. Also suitable for making castings.<br />
* '''Power''' - the rate of delivery of energy<br />
* '''Rectifier''' - A semiconductor device that turns AC into DC for charging the battery.<br />
* '''Root''' - The widest part of the blade near to the hub at the center of the rotor.<br />
* '''Rotor''' - A rotating part. Magnet rotors are the steel diskscarrying the magnets past the stator. Rotor blades are the 'propeller' <br />
driven by the wind and driving the magnet rotors.<br />
* '''Soldering''' - A method for making electrical connections between wires using a hot 'iron' and coating everything with molten solder.<br />
* '''Drag''' - A force exerted by the wind on an object. Drag is parallel to the wind direction at the object. (see Lift) <br />
* '''Stator''' - An assembly of coils embedded in a slab of resin to form part of the alternator. The magnets induce a voltage in the coils and we can use this to charge a battery.<br />
* '''Drop''' - Used here to describe a certain measurement of the shape of a windmill blade. The 'drop' affects the angle of<br />
the blade to the wind. Styrene monomer - A nasty smelling solvent in the polyester resin mix.<br />
* '''Flux''' - The 'stuff' of magnetism. Similar to 'current' in electricity. It can be visualized as 'lines' coming out of one pole and <br />
returning to the other.<br />
* '''Furling''' - A protective action that reduces exposure to violent winds by facing the blades away from them.<br />
* '''Jig''' - A device used to hold the magnets in place before setting them in resin.<br />
* '''Leading edge''' - The edge of a blade that would strike an object placed in its path as the rotor spins.<br />
* '''Lift''' - A force exerted by the wind on an object. Lift is at right angles to the wind direction at the object. (see Drag)<br />
* '''Mold''' - A shaped container in which resin castings are formed. The mould can be discarded after the casting has set.<br />
* '''Multimeter''' - A versatile electrical test instrument, used to measure voltage, current and other parameters.<br />
* '''Neodymium''' - The name given to a type of permanent magnet containing neodymium, iron and boron. These magnets are very strong and <br />
getting cheaper all the time.<br />
* '''Offset''' - An eccentric position, off centre.<br />
* '''Talcum powder'''- A cheap filler powder used to thicken the resin and slow its reaction (prevent it overheating).<br />
* '''Tail''' - A projecting vane mounted on a boom at the back ofthe windmill used to steer it into or out of the wind automatically.<br />
* '''Tap''' - a tool for making thread inside holes so you can fit a screw into the hole.<br />
* '''Thrust''' - The force of the wind pushing the machine backwards.<br />
* '''Tower''' - The mast supporting the windmill.<br />
* '''Trailing edge''' - The blade edge furthest from the leading edge. The trailing edge is sharpened, so as to release the passing <br />
air without turbulence.<br />
* '''Wedges''' - Tapered pieces of wood used to build up the blade thickness and increase its angle to the wind near the root.<br />
* '''Work-piece''' - The piece of wood or metal being shaped in the workshop.<br />
* '''Yaw bearing''' - the swivel at the top of the tower on which the windmill is mounted. The yaw bearing allows the windmill to face the wind.<br />

== The space == <br />
<br />
=== The Foundry ===<br />
The Foundry is a non-profit organization based in a previously abandoned GaliZA village. It functions both as a residency and as a project space. It subscribes to the ideals of self-organization, and has the following three objectives:<br />
1. Organizing activities in the field of the arts, science and humanities outside of traditional institutions, focusing on critical discourse.<br />
2. Promoting the exchange of ideas and intellectual collaboration outside of the constraints imposed by state and market.<br />
3. Increasing self-sufficiency, sustainability, and an awareness of the environment using appropriate technology and open source as main resources.<br />
Taking into account this context, our aim is to reinforce the capacity to generate networks flowing from rural to urban context supporting non hierarchy and democratic exchanges of knowledge and practices that can enable new and sustainable models within rural contexts. According to that we consider that the new trans-disciplinary creative sectors in which we are entangled can have a huge and positive impact in the creation of this new paradigm. https://bravosfoundry.com/<br />
Aside from that, there is thematic focus on transdisciplinarity, transfeminism and post-humanism. While this focus is not adequately grasped by identity-political categories like race or gender, we hope it leads to the subversion of hegemonic structures inscribed in the binarisms upholding many of these categories. Our interest lies in the development of tools and technologies that subvert contemporary structures of domination, exploitation and marginalization, not in those that reproduce it.<br />
We seek to develop a more sustainable environment by opening up our practices based on a free culture framework, generating networks and interest around them, enabling a flow of exchange of innovation across creative sectors focusing on revaluation of rural contexts and its knowledge heritage.<br />

=== '''Section 2, involves the construction of '''the alternator''' parts using the devices from the section 1.''' ===<br />
<br />
'''Alternator'''<br />
Each magnet rotor is a steel disk with 12 magnets placed on it and set in resin. The magnets are each 50 x 50 x 20 mm, and they only just fit on the disk. The idea is to achieve the maximum amount of flux in a given space.<br />
The turbine runs at 650 rpm for 400W output, so the centrifugal force on the magnets is 60 times the force of gravity. To prevent them flying off, the resin casting needs to be reinforced. Stainless steel wire rope is placed around the outside of the magnets to hold the casting together at high rpm. We use stainless because it is non-magnetic, or at least less magnetic than normal steel wire rope. <br />
<br />
You will wind the coils that produce the output power and cast them in resin to form a stator between the two magnet rotors. Photos of the final pieces here <br />

[[File:prod05.jpg|300px]] <br />
<br />
Step - Generator, rotor: Preparation of the wheel hub.<br />
<br />
[[File:frame10.jpg|300px]]<br />
<br />
'''The wheel hub'''<br />
<br />
You can find a used car rear wheel hub (Golf, Toyota, etc.) that has a simple way to<br />
attach the axle, or alternatively buy a trailer hubs online new at low cost.<br />
PCD or ‘pitch circle diameter' is the diameter of the circle of the hole pattern in the<br />
hub, and usually this will be 100mm for a car wheel hub, or 4 inches for a trailer hub.<br />
Car hubs may have a brake-drum that you do not need. This can be removed using a<br />
cutting disk on a grinder. The simplest approach is to make four straight cuts around<br />
the four holes in the front, leaving a square surface to which you mount the magnet<br />
rotors. These photos show a golf rear wheel hub – first the brake-drum being cut, and<br />
then the finished hub after cutting off the drum.A typical rear wheel car hub with a <br />
flange on the back end of the stub shaft that can reused to mount it.<br />
Trailer hubs on the other hand are rather basic quality, and the bearings may be too<br />
cheap for long term use, but they are readily available items that can be purchased<br />
online as new. The drawings below (from autow.com) show a typical hub and stub<br />
axle which are bought separately.<br />
You need to be ready to replace the bearings with a named brand (such as SKF). It’s<br />
easy to replace the inner cones and rollers but the outer shells need to be knocked<br />
gently out of the hub with a suitable drift. Keep them straight by tapping evenly on<br />
opposite sides, and take care not to scratch the seating.<br />

Step - Generator, rotor: PreStep<br />
<br />
=== Section 4, involves the craving of the blades and the welding of the base for the turbine generator. ===<br />
<br />
4.1 Making the blades <br />
The drawknife is useful for thicker chunks of wood, and for cutting down into a hollow. <br />
It can make a nice smooth job of the root of the blade, whereas the plane will work better <br />
where you need a very straight finish.<br />
<br />
'''Marking the stations.'''<br />
<br />
Place the blade with its best edge toward you on its upper surface. This will actually<br />
become the back or ‘downwind’ side of the finished blade.<br />
(Most of the front or windward side is to be cut off, so defects on this underneath side<br />
are not important.)<br />
<br />
The root of the blade will be on your right, the tip at the left, 1000 mm from the root<br />
(near the left end).<br />
<br />
Measure from the root, and mark four stations.<br />
Station A at 75mm<br />
Station B at 150 mm<br />
Station C at 500 mm<br />
The Tip at 1000 mm.<br />
<br />
<br />
At each station draw a line right around the workpiece using a square.<br />
<br />
[[File:01tur.jpeg|400px]]<br />
<br />
<br />
'''Tapering the blade'''<br />
The width of the blade tapers down from full size at station C to 55 mm wide at the<br />
tip. Mark the 55 mm tip width, measuring from the leading edge side. Draw a line<br />
though your mark to the trailing edge side at C station and cut off a triangular piece so<br />
as to achieve the correct tapered shape for the blade. Any knots in the triangular<br />
off cut do not matter as this piece is discarded. Try to make this a "square" cut,<br />
perpendicular to the back surface of the blade.<br />
You can do this with a circular saw, or by cross-cutting and shaving as described<br />
above.<br />
<br />
<br />
[[File:02tur.jpeg|400px]]<br />
<br />
'''Marking the leading and trailing edges'''<br />
The next step is to cut the windward face of the blade. This face is defined by the<br />
leading and trailing edge lines of the blade. These lines need to be marked with<br />
reference to the back face of the wood which has been uppermost in the previous<br />
operation.<br />
<br />
Turn the wood over. Start by drawing two diagonal lines between stations A and B<br />
on the front or windward side (see below). One is on the front face and the other on<br />
the trailing edge which is now toward you. <br />
<br />
[[File:03tur.jpeg|400px]]<br />
<br />
<br />
Now draw the leading edge line as shown below, <br />
from station B, down to 16mm(from the back) at station C, then continuing to the tip at<br />
7mm from the back.<br />
<br />
[[File:04tur.jpeg|400px]]<br />
<br />
<br />
(This drawing does not show the extra bit beyond the tip which may remain <br />
in your actual workpiece.)<br />
<br />
Measurements are summarised in this table below. Heights are from the back of the<br />
blade which will then rest on the bench. Remove the wood above this height. "Full"<br />
refers to the full thickness of the original piece of wood you are using.<br />
<br />
<br />
<br />
[[File:05tur.jpeg|400px]]<br />
<br />
<br />
'''The trailing''' <br />
The trailing edge line starts at the bottom of the diagonal line at station B, and <br />
rises to 5mm at C, continuing at 5 mm to the tip. This view below shows the wood <br />
already removed between the two lines to form the windward face of the blade.<br />
<br />
<br />
[[File:06tur.png|400px]]<br />
<br />
<br />
Carve this flat windward face between the 2 lines. Take care that the edges are<br />
straight, following the lines. The best tool to use for finishing the outer part of the<br />
blade is a plane, to give a smooth, straight finish. You may need to work the plane at<br />
45 degrees to the workpiece, sliding partly sideways, to form the hollow shape at<br />
station C.<br />
<br />
This step is completed when you can place a ruler across the face between the leading<br />
and trailing edge lines and there is no ‘hump’ in the middle. Fill any chips or small<br />
hollows with wood filler. If there are any serious errors, or large knots that weaken<br />
the blade then it may have to be discarded.<br />
Check the “drop” using a level as a reference. Clamp the wood so that the root part<br />
sits level, and measure the difference in level between the leading and trailing edges.<br />
The difference or “drop” should be 11 mm at the 500 mm mid-point, and 2 mm at the<br />
tip.<br />

"Pedagoxías do vento e das estrelas. As relacións sociais ás que (nunca estabamos destinados a) sobrevivir, tamén vivimos nos nosos corpos dolorosamente, e Audre Lorde non está aquí para lembrarnos esta lección, salvo na medida en que está presente no vento pedagóxico.<br />
Pero o vento é o noso mestre (74). -Alexis Pauline Gumbs "<br />
<br />
O principal obxectivo deste evento é prototipar un xerador eólico a pequena escala para camiñar xuntos cara á autosuficiencia neste campo.<br />
Temos o pracer de comunicarvos que do 16 ao 23 de outubro Biotranslab de Pin e The Foundry establecen unha colaboración para levar a cabo o evento Eco (i) Logic Queer Energy harvesting. O proxecto é posible grazas ao apoio de GOSH, unha rede para desenvolver e difundir proxectos baseados en hardware de código aberto para a ciencia.<br />
<br />
EcoLoxicas Queer para a captación de enerxía eolica. <br />
O evento ten como obxectivo abordar a falta de mulleres, queer, trans e diversidade nos ámbitos tecnolóxicos en xeral e do hacking máis concretamente. Pero aínda máis, pretende crear unha comunidade que avalía criticamente as narrativas hexemónicas arredor das tecnoloxías, os aspectos de modernidade dos seus supostos occidentais subliñados e as súas inflexións capitalistas inherentes, entre outros.<br />
O obxectivo principal do evento é desenvolver kits que se centren na interacción co medio natural no ámbito da enerxía.. o obxectivo principal pasa pola captación de enerxía do medio natural, a través dos aeroxeradores. Estes kits de enerxía serán escalables e poderán utilizarse tanto como material pedagóxico como para instalar centrais eléctricas específicas do sitio en diferentes sitios tamén. Este traballo ten un compoñente contrainfraestrutural: unha posible consecuencia sería capacitar ás persoas para xerar a súa propia enerxía en lugar de depender de grandes empresas e moitas veces extractivas.<br />

''Pedagogies of the Wind and Stars. The social relations that we (were never meant to) survive, also live in our bodies painfully, and Audre Lorde is not here to remind us of this lesson herself, except in as much that she is present in the pedagogical wind. But wind is our teacher (74). -Alexis Pauline Gumbs'' from the book Mapping Queer Space(s) of Praxis and Pedagogy <br />
Editors: Elizabeth McNeil, James E. Wermers, Joshua O. Lunn'' <br />
<br />
We have the pleasure to communicate you that from 16 to 29 of October Pin Biotranslab, Casa do Río e The Foundry establishes a collaboration to run the event Eco (i) Logic Queer Energy harvesting. The project is possible thanks to the support of GOSH, an network for develop and disseminate projects based on Open Source hardware for Science.<br />
<br />
'''Eco (i) Logic Queer Energy harvesting''' <br />
The event aims at addressing the lack of women, queer, trans and diversity in technological fields in general and hacking more specifically. But even more so, it aims at creating a community that critically assesses the hegemonic narratives around technologies, the modernity aspects of its underlining Western assumptions and its inherent capitalist inflections, among others.<br />
The main purpose of the event is to develop kits that focus on interacting with the natural environment on the field of energy.. the main objective lies on harvesting energy of the natural environment, through wind turbines. These power kits will be scalable and can be used both as pedagogical material and to set up site-specific power plants in different sites as well. There is a counter-infrastructural component to this work: one possible consequence would be to empower people to generate their own energy instead of relying on large and often extractive companies.<br />
<br />
== Introduction and values of the process ==<br />
<br />
Here starts the documentation of the long process of the prototyping the Hugh Piggott The Piggott Turbine – Wind Empowerment model of an Open source wind turbine. We were changing a bit the goals of the event from developing small kits to going to build the real 2m size wind turbine to provide energy to the rural regional areas we were working on. In that specific event we were working at The Foundry a nice project and association that we have settled on the north part of GaliZA into the Northwest of Spain.<br />
<br />
During the event many things have been activated between the doers and the visitors; In general It was a wondering experience full of new things to study, learn, doing and understand together. <br />
<br />
We chose this model because It was full of layers of interest on the levels of learning, understanding and making it, here some levels mixed up with layers: <br />
<br />
first to all is one of the ones that is '''open source''' or at least has the option to access the full documentation.<br />
<br />
really '''rich on the pedagogical level''', we were really learning through the complete building of the generator itself, about many topics as :<br />
* electromagnetism<br />
* mathematics<br />
* geometry<br />
* electronics<br />
* AC-DC<br />
* welding<br />
* wood carving<br />
* sculpting and casting pieces<br />
and much more that was reaching through the nice process of reading, learning and building together.<br />
<br />
== Glossary ==<br />
<br />
* '''AC-'''Alternating current as produced by the alternator. All thread - USA word for 'threaded' or 'spun' rod or studding<br />
* '''Brake switch''' - A switch used to short-circuit the wires from the alternator so that it stops.<br />
* '''Catalyst''' - A chemical used to make the polyester resin set solid. Catalyst reacts with 'accelerator' already present in the resin mix. <br />
The heat of reaction sets the polyester.<br />
* '''Cavalier''' - A make of car. The cavalier in the UK is not the same as the Cavalier in the USA but both have useful wheel hubs.<br />
* '''DC - direct current''' with a positive and a negative side, as in battery circuits.<br />
* '''Diameter''' - The distance from one side of a circle to another. The width of a disk right across the middle.<br />
* '''Phase''' - The timing of the cyclical alternation of voltage in a circuit. Different phases will peak at different times.<br />
* '''Polyester''' - A type of resin used in fibreglass work. Also suitable for making castings.<br />
* '''Power''' - the rate of delivery of energy<br />
* '''Rectifier''' - A semiconductor device that turns AC into DC for charging the battery.<br />
* '''Root''' - The widest part of the blade near to the hub at the center of the rotor.<br />
* '''Rotor''' - A rotating part. Magnet rotors are the steel diskscarrying the magnets past the stator. Rotor blades are the 'propeller' <br />
driven by the wind and driving the magnet rotors.<br />
* '''Soldering''' - A method for making electrical connections between wires using a hot 'iron' and coating everything with molten solder.<br />
* '''Drag''' - A force exerted by the wind on an object. Drag is parallel to the wind direction at the object. (see Lift) <br />
* '''Stator''' - An assembly of coils embedded in a slab of resin to form part of the alternator. The magnets induce a voltage in the coils and we can use this to charge a battery.<br />
* '''Drop''' - Used here to describe a certain measurement of the shape of a windmill blade. The 'drop' affects the angle of<br />
the blade to the wind. Styrene monomer - A nasty smelling solvent in the polyester resin mix.<br />
* '''Flux''' - The 'stuff' of magnetism. Similar to 'current' in electricity. It can be visualized as 'lines' coming out of one pole and <br />
returning to the other.<br />
* '''Furling''' - A protective action that reduces exposure to violent winds by facing the blades away from them.<br />
* '''Jig''' - A device used to hold the magnets in place before setting them in resin.<br />
* '''Leading edge''' - The edge of a blade that would strike an object placed in its path as the rotor spins.<br />
* '''Lift''' - A force exerted by the wind on an object. Lift is at right angles to the wind direction at the object. (see Drag)<br />
* '''Mold''' - A shaped container in which resin castings are formed. The mould can be discarded after the casting has set.<br />
* '''Multimeter''' - A versatile electrical test instrument, used to measure voltage, current and other parameters.<br />
* '''Neodymium''' - The name given to a type of permanent magnet containing neodymium, iron and boron. These magnets are very strong and <br />
getting cheaper all the time.<br />
* '''Offset''' - An eccentric position, off centre.<br />
* '''Talcum powder'''- A cheap filler powder used to thicken the resin and slow its reaction (prevent it overheating).<br />
* '''Tail''' - A projecting vane mounted on a boom at the back ofthe windmill used to steer it into or out of the wind automatically.<br />
* '''Tap''' - a tool for making thread inside holes so you can fit a screw into the hole.<br />
* '''Thrust''' - The force of the wind pushing the machine backwards.<br />
* '''Tower''' - The mast supporting the windmill.<br />
* '''Trailing edge''' - The blade edge furthest from the leading edge. The trailing edge is sharpened, so as to release the passing <br />
air without turbulence.<br />
* '''Wedges''' - Tapered pieces of wood used to build up the blade thickness and increase its angle to the wind near the root.<br />
* '''Work-piece''' - The piece of wood or metal being shaped in the workshop.<br />
* '''Yaw bearing''' - the swivel at the top of the tower on which the windmill is mounted. The yaw bearing allows the windmill to face the wind.<br />

== The space == <br />
<br />
=== The Foundry ===<br />
The Foundry is a non-profit organization based in a previously abandoned GaliZA village. It functions both as a residency and as a project space. It subscribes to the ideals of self-organization, and has the following three objectives:<br />
1. Organizing activities in the field of the arts, science and humanities outside of traditional institutions, focusing on critical discourse.<br />
2. Promoting the exchange of ideas and intellectual collaboration outside of the constraints imposed by state and market.<br />
3. Increasing self-sufficiency, sustainability, and an awareness of the environment using appropriate technology and open source as main resources.<br />
Taking into account this context, our aim is to reinforce the capacity to generate networks flowing from rural to urban context supporting non hierarchy and democratic exchanges of knowledge and practices that can enable new and sustainable models within rural contexts. According to that we consider that the new trans-disciplinary creative sectors in which we are entangled can have a huge and positive impact in the creation of this new paradigm. https://bravosfoundry.com/<br />
Aside from that, there is thematic focus on transdisciplinarity, transfeminism and post-humanism. While this focus is not adequately grasped by identity-political categories like race or gender, we hope it leads to the subversion of hegemonic structures inscribed in the binarisms upholding many of these categories. Our interest lies in the development of tools and technologies that subvert contemporary structures of domination, exploitation and marginalization, not in those that reproduce it.<br />
We seek to develop a more sustainable environment by opening up our practices based on a free culture framework, generating networks and interest around them, enabling a flow of exchange of innovation across creative sectors focusing on revaluation of rural contexts and its knowledge heritage.<br />

=== '''Section 2, involves the construction of '''the alternator''' parts using the devices from the section 1.''' ===<br />
<br />
'''Alternator'''<br />
Each magnet rotor is a steel disk with 12 magnets placed on it and set in resin. The magnets are each 50 x 50 x 20 mm, and they only just fit on the disk. The idea is to achieve the maximum amount of flux in a given space.<br />
The turbine runs at 650 rpm for 400W output, so the centrifugal force on the magnets is 60 times the force of gravity. To prevent them flying off, the resin casting needs to be reinforced. Stainless steel wire rope is placed around the outside of the magnets to hold the casting together at high rpm. We use stainless because it is non-magnetic, or at least less magnetic than normal steel wire rope. <br />
<br />
You will wind the coils that produce the output power and cast them in resin to form a stator between the two magnet rotors. Photos of the final pieces here <br />

[[File:prod05.jpg|300px]] <br />
<br />
Step - Generator, rotor: Preparation of the wheel hub.<br />
<br />
[[File:frame10.jpg|300px]]<br />
<br />
'''The wheel hub'''<br />
<br />
You can find a used car rear wheel hub (Golf, Toyota, etc.) that has a simple way to<br />
attach the axle, or alternatively buy a trailer hubs online new at low cost.<br />
PCD or ‘pitch circle diameter' is the diameter of the circle of the hole pattern in the<br />
hub, and usually this will be 100mm for a car wheel hub, or 4 inches for a trailer hub.<br />
Car hubs may have a brake-drum that you do not need. This can be removed using a<br />
cutting disk on a grinder. The simplest approach is to make four straight cuts around<br />
the four holes in the front, leaving a square surface to which you mount the magnet<br />
rotors. These photos show a golf rear wheel hub – first the brake-drum being cut, and<br />
then the finished hub after cutting off the drum.A typical rear wheel car hub with a <br />
flange on the back end of the stub shaft that can reused to mount it.<br />
Trailer hubs on the other hand are rather basic quality, and the bearings may be too<br />
cheap for long term use, but they are readily available items that can be purchased<br />
online as new. The drawings below (from autow.com) show a typical hub and stub<br />
axle which are bought separately.<br />
You need to be ready to replace the bearings with a named brand (such as SKF). It’s<br />
easy to replace the inner cones and rollers but the outer shells need to be knocked<br />
gently out of the hub with a suitable drift. Keep them straight by tapping evenly on<br />
opposite sides, and take care not to scratch the seating.<br />

Step - Generator, rotor: PreStep<br />
<br />
=== Section 4, involves the craving of the blades and the welding of the base for the turbine generator. ===<br />
<br />
4.1 Making the blades <br />
The drawknife is useful for thicker chunks of wood, and for cutting down into a hollow. <br />
It can make a nice smooth job of the root of the blade, whereas the plane will work better <br />
where you need a very straight finish.<br />
<br />
'''Marking the stations.'''<br />
<br />
Place the blade with its best edge toward you on its upper surface. This will actually<br />
become the back or ‘downwind’ side of the finished blade.<br />
(Most of the front or windward side is to be cut off, so defects on this underneath side<br />
are not important.)<br />
<br />
The root of the blade will be on your right, the tip at the left, 1000 mm from the root<br />
(near the left end).<br />
<br />
Measure from the root, and mark four stations.<br />
Station A at 75mm<br />
Station B at 150 mm<br />
Station C at 500 mm<br />
The Tip at 1000 mm.<br />
<br />
<br />
At each station draw a line right around the workpiece using a square.<br />
<br />
[[File:01tur.jpeg|400px]]<br />
<br />
<br />
'''Tapering the blade'''<br />
The width of the blade tapers down from full size at station C to 55 mm wide at the<br />
tip. Mark the 55 mm tip width, measuring from the leading edge side. Draw a line<br />
though your mark to the trailing edge side at C station and cut off a triangular piece so<br />
as to achieve the correct tapered shape for the blade. Any knots in the triangular<br />
off cut do not matter as this piece is discarded. Try to make this a "square" cut,<br />
perpendicular to the back surface of the blade.<br />
You can do this with a circular saw, or by cross-cutting and shaving as described<br />
above.<br />
<br />
<br />
[[File:02tur.jpeg|400px]]<br />
<br />
'''Marking the leading and trailing edges'''<br />
The next step is to cut the windward face of the blade. This face is defined by the<br />
leading and trailing edge lines of the blade. These lines need to be marked with<br />
reference to the back face of the wood which has been uppermost in the previous<br />
operation.<br />
<br />
Turn the wood over. Start by drawing two diagonal lines between stations A and B<br />
on the front or windward side (see below). One is on the front face and the other on<br />
the trailing edge which is now toward you. <br />
<br />
[[File:03tur.jpeg|400px]]<br />
<br />
<br />
Now draw the leading edge line as shown below, <br />
from station B, down to 16mm(from the back) at station C, then continuing to the tip at<br />
7mm from the back.<br />
<br />
[[File:04tur.jpeg|400px]]<br />
<br />
<br />
(This drawing does not show the extra bit beyond the tip which may remain <br />
in your actual workpiece.)<br />
<br />
Measurements are summarised in this table below. Heights are from the back of the<br />
blade which will then rest on the bench. Remove the wood above this height. "Full"<br />
refers to the full thickness of the original piece of wood you are using.<br />
<br />
<br />
<br />
[[File:05tur.jpeg|400px]]<br />
<br />
<br />
'''The trailing''' <br />
The trailing edge line starts at the bottom of the diagonal line at station B, and <br />
rises to 5mm at C, continuing at 5 mm to the tip. This view below shows the wood <br />
already removed between the two lines to form the windward face of the blade.<br />
<br />
<br />
[[File:06tur.png|400px]]<br />
<br />
<br />
Carve this flat windward face between the 2 lines. Take care that the edges are<br />
straight, following the lines. The best tool to use for finishing the outer part of the<br />
blade is a plane, to give a smooth, straight finish. You may need to work the plane at<br />
45 degrees to the workpiece, sliding partly sideways, to form the hollow shape at<br />
station C.<br />
<br />
This step is completed when you can place a ruler across the face between the leading<br />
and trailing edge lines and there is no ‘hump’ in the middle. Fill any chips or small<br />
hollows with wood filler. If there are any serious errors, or large knots that weaken<br />
the blade then it may have to be discarded.<br />
Check the “drop” using a level as a reference. Clamp the wood so that the root part<br />
sits level, and measure the difference in level between the leading and trailing edges.<br />
The difference or “drop” should be 11 mm at the 500 mm mid-point, and 2 mm at the<br />
tip.<br />

"Pedagoxías do vento e das estrelas. As relacións sociais ás que (nunca estabamos destinados a) sobrevivir, tamén vivimos nos nosos corpos dolorosamente, e Audre Lorde non está aquí para lembrarnos esta lección, salvo na medida en que está presente no vento pedagóxico.<br />
Pero o vento é o noso mestre (74). -Alexis Pauline Gumbs "<br />
<br />
O principal obxectivo deste evento é prototipar un xerador eólico a pequena escala para camiñar xuntos cara á autosuficiencia neste campo.<br />
Temos o pracer de comunicarvos que do 16 ao 23 de outubro Biotranslab de Pin e The Foundry establecen unha colaboración para levar a cabo o evento Eco (i) Logic Queer Energy harvesting. O proxecto é posible grazas ao apoio de GOSH, unha rede para desenvolver e difundir proxectos baseados en hardware de código aberto para a ciencia.<br />
<br />
EcoLoxicas Queer para a captación de enerxía eolica. <br />
O evento ten como obxectivo abordar a falta de mulleres, queer, trans e diversidade nos ámbitos tecnolóxicos en xeral e do hacking máis concretamente. Pero aínda máis, pretende crear unha comunidade que avalía criticamente as narrativas hexemónicas arredor das tecnoloxías, os aspectos de modernidade dos seus supostos occidentais subliñados e as súas inflexións capitalistas inherentes, entre outros.<br />
O obxectivo principal do evento é desenvolver kits que se centren na interacción co medio natural no ámbito da enerxía.. o obxectivo principal pasa pola captación de enerxía do medio natural, a través dos aeroxeradores. Estes kits de enerxía serán escalables e poderán utilizarse tanto como material pedagóxico como para instalar centrais eléctricas específicas do sitio en diferentes sitios tamén. Este traballo ten un compoñente contrainfraestrutural: unha posible consecuencia sería capacitar ás persoas para xerar a súa propia enerxía en lugar de depender de grandes empresas e moitas veces extractivas.<br />

''Pedagogies of the Wind and Stars. The social relations that we (were never meant to) survive, also live in our bodies painfully, and Audre Lorde is not here to remind us of this lesson herself, except in as much that she is present in the pedagogical wind. But wind is our teacher (74). -Alexis Pauline Gumbs'' from the book Mapping Queer Space(s) of Praxis and Pedagogy <br />
Editors: Elizabeth McNeil, James E. Wermers, Joshua O. Lunn'' <br />
<br />
We have the pleasure to communicate you that from 16 to 29 of October Pin Biotranslab, Casa do Río e The Foundry establishes a collaboration to run the event Eco (i) Logic Queer Energy harvesting. The project is possible thanks to the support of GOSH, an network for develop and disseminate projects based on Open Source hardware for Science.<br />
<br />
'''Eco (i) Logic Queer Energy harvesting''' <br />
The event aims at addressing the lack of women, queer, trans and diversity in technological fields in general and hacking more specifically. But even more so, it aims at creating a community that critically assesses the hegemonic narratives around technologies, the modernity aspects of its underlining Western assumptions and its inherent capitalist inflections, among others.<br />
The main purpose of the event is to develop kits that focus on interacting with the natural environment on the field of energy.. the main objective lies on harvesting energy of the natural environment, through wind turbines. These power kits will be scalable and can be used both as pedagogical material and to set up site-specific power plants in different sites as well. There is a counter-infrastructural component to this work: one possible consequence would be to empower people to generate their own energy instead of relying on large and often extractive companies.<br />
<br />
== Introduction and values of the process ==<br />
<br />
Here starts the documentation of the long process of the prototyping the Hugh Piggott The Piggott Turbine – Wind Empowerment model of an Open source wind turbine. We were changing a bit the goals of the event from developing small kits to going to build the real 2m size wind turbine to provide energy to the rural regional areas we were working on. In that specific event we were working at The Foundry a nice project and association that we have settled on the north part of GaliZA into the Northwest of Spain.<br />
<br />
During the event many things have been activated between the doers and the visitors; In general It was a wondering experience full of new things to study, learn, doing and understand together. <br />
<br />
We chose this model because It was full of layers of interest on the levels of learning, understanding and making it, here some levels mixed up with layers: <br />
<br />
first to all is one of the ones that is '''open source''' or at least has the option to access the full documentation.<br />
<br />
really '''rich on the pedagogical level''', we were really learning through the complete building of the generator itself, about many topics as :<br />
* electromagnetism<br />
* mathematics<br />
* geometry<br />
* electronics<br />
* AC-DC<br />
* welding<br />
* wood carving<br />
* sculpting and casting pieces<br />
and much more that was reaching through the nice process of reading, learning and building together.<br />
<br />
== Glossary ==<br />
<br />
* '''AC-'''Alternating current as produced by the alternator. All thread - USA word for 'threaded' or 'spun' rod or studding<br />
* '''Brake switch''' - A switch used to short-circuit the wires from the alternator so that it stops.<br />
* '''Catalyst''' - A chemical used to make the polyester resin set solid. Catalyst reacts with 'accelerator' already present in the resin mix. <br />
The heat of reaction sets the polyester.<br />
* '''Cavalier''' - A make of car. The cavalier in the UK is not the same as the Cavalier in the USA but both have useful wheel hubs.<br />
* '''DC - direct current''' with a positive and a negative side, as in battery circuits.<br />
* '''Diameter''' - The distance from one side of a circle to another. The width of a disk right across the middle.<br />
* '''Phase''' - The timing of the cyclical alternation of voltage in a circuit. Different phases will peak at different times.<br />
* '''Polyester''' - A type of resin used in fibreglass work. Also suitable for making castings.<br />
* '''Power''' - the rate of delivery of energy<br />
* '''Rectifier''' - A semiconductor device that turns AC into DC for charging the battery.<br />
* '''Root''' - The widest part of the blade near to the hub at the center of the rotor.<br />
* '''Rotor''' - A rotating part. Magnet rotors are the steel diskscarrying the magnets past the stator. Rotor blades are the 'propeller' <br />
driven by the wind and driving the magnet rotors.<br />
* '''Soldering''' - A method for making electrical connections between wires using a hot 'iron' and coating everything with molten solder.<br />
* '''Drag''' - A force exerted by the wind on an object. Drag is parallel to the wind direction at the object. (see Lift) <br />
* '''Stator''' - An assembly of coils embedded in a slab of resin to form part of the alternator. The magnets induce a voltage in the coils and we can use this to charge a battery.<br />
* '''Drop''' - Used here to describe a certain measurement of the shape of a windmill blade. The 'drop' affects the angle of<br />
the blade to the wind. Styrene monomer - A nasty smelling solvent in the polyester resin mix.<br />
* '''Flux''' - The 'stuff' of magnetism. Similar to 'current' in electricity. It can be visualized as 'lines' coming out of one pole and <br />
returning to the other.<br />
* '''Furling''' - A protective action that reduces exposure to violent winds by facing the blades away from them.<br />
* '''Jig''' - A device used to hold the magnets in place before setting them in resin.<br />
* '''Leading edge''' - The edge of a blade that would strike an object placed in its path as the rotor spins.<br />
* '''Lift''' - A force exerted by the wind on an object. Lift is at right angles to the wind direction at the object. (see Drag)<br />
* '''Mold''' - A shaped container in which resin castings are formed. The mould can be discarded after the casting has set.<br />
* '''Multimeter''' - A versatile electrical test instrument, used to measure voltage, current and other parameters.<br />
* '''Neodymium''' - The name given to a type of permanent magnet containing neodymium, iron and boron. These magnets are very strong and <br />
getting cheaper all the time.<br />
* '''Offset''' - An eccentric position, off centre.<br />
* '''Talcum powder'''- A cheap filler powder used to thicken the resin and slow its reaction (prevent it overheating).<br />
* '''Tail''' - A projecting vane mounted on a boom at the back ofthe windmill used to steer it into or out of the wind automatically.<br />
* '''Tap''' - a tool for making thread inside holes so you can fit a screw into the hole.<br />
* '''Thrust''' - The force of the wind pushing the machine backwards.<br />
* '''Tower''' - The mast supporting the windmill.<br />
* '''Trailing edge''' - The blade edge furthest from the leading edge. The trailing edge is sharpened, so as to release the passing <br />
air without turbulence.<br />
* '''Wedges''' - Tapered pieces of wood used to build up the blade thickness and increase its angle to the wind near the root.<br />
* '''Work-piece''' - The piece of wood or metal being shaped in the workshop.<br />
* '''Yaw bearing''' - the swivel at the top of the tower on which the windmill is mounted. The yaw bearing allows the windmill to face the wind.<br />

== The space == <br />
<br />
=== The Foundry ===<br />
The Foundry is a non-profit organization based in a previously abandoned GaliZA village. It functions both as a residency and as a project space. It subscribes to the ideals of self-organization, and has the following three objectives:<br />
1. Organizing activities in the field of the arts, science and humanities outside of traditional institutions, focusing on critical discourse.<br />
2. Promoting the exchange of ideas and intellectual collaboration outside of the constraints imposed by state and market.<br />
3. Increasing self-sufficiency, sustainability, and an awareness of the environment using appropriate technology and open source as main resources.<br />
Taking into account this context, our aim is to reinforce the capacity to generate networks flowing from rural to urban context supporting non hierarchy and democratic exchanges of knowledge and practices that can enable new and sustainable models within rural contexts. According to that we consider that the new trans-disciplinary creative sectors in which we are entangled can have a huge and positive impact in the creation of this new paradigm. https://bravosfoundry.com/<br />
Aside from that, there is thematic focus on transdisciplinarity, transfeminism and post-humanism. While this focus is not adequately grasped by identity-political categories like race or gender, we hope it leads to the subversion of hegemonic structures inscribed in the binarisms upholding many of these categories. Our interest lies in the development of tools and technologies that subvert contemporary structures of domination, exploitation and marginalization, not in those that reproduce it.<br />
We seek to develop a more sustainable environment by opening up our practices based on a free culture framework, generating networks and interest around them, enabling a flow of exchange of innovation across creative sectors focusing on revaluation of rural contexts and its knowledge heritage.<br />

=== '''Section 2, involves the construction of '''the alternator''' parts using the devices from the section 1.''' ===<br />
<br />
'''Alternator'''<br />
Each magnet rotor is a steel disk with 12 magnets placed on it and set in resin. The magnets are each 50 x 50 x 20 mm, and they only just fit on the disk. The idea is to achieve the maximum amount of flux in a given space.<br />
The turbine runs at 650 rpm for 400W output, so the centrifugal force on the magnets is 60 times the force of gravity. To prevent them flying off, the resin casting needs to be reinforced. Stainless steel wire rope is placed around the outside of the magnets to hold the casting together at high rpm. We use stainless because it is non-magnetic, or at least less magnetic than normal steel wire rope. <br />
<br />
You will wind the coils that produce the output power and cast them in resin to form a stator between the two magnet rotors. Photos of the final pieces here <br />

[[File:prod05.jpg|300px]] <br />
<br />
Step - Generator, rotor: Preparation of the wheel hub.<br />
<br />
[[File:frame10.jpg|300px]]<br />
<br />
'''The wheel hub'''<br />
<br />
You can find a used car rear wheel hub (Golf, Toyota, etc.) that has a simple way to<br />
attach the axle, or alternatively buy a trailer hubs online new at low cost.<br />
PCD or ‘pitch circle diameter' is the diameter of the circle of the hole pattern in the<br />
hub, and usually this will be 100mm for a car wheel hub, or 4 inches for a trailer hub.<br />
Car hubs may have a brake-drum that you do not need. This can be removed using a<br />
cutting disk on a grinder. The simplest approach is to make four straight cuts around<br />
the four holes in the front, leaving a square surface to which you mount the magnet<br />
rotors. These photos show a golf rear wheel hub – first the brake-drum being cut, and<br />
then the finished hub after cutting off the drum.A typical rear wheel car hub with a <br />
flange on the back end of the stub shaft that can reused to mount it.<br />
Trailer hubs on the other hand are rather basic quality, and the bearings may be too<br />
cheap for long term use, but they are readily available items that can be purchased<br />
online as new. The drawings below (from autow.com) show a typical hub and stub<br />
axle which are bought separately.<br />
You need to be ready to replace the bearings with a named brand (such as SKF). It’s<br />
easy to replace the inner cones and rollers but the outer shells need to be knocked<br />
gently out of the hub with a suitable drift. Keep them straight by tapping evenly on<br />
opposite sides, and take care not to scratch the seating.<br />

Step - Generator, rotor: PreStep<br />
<br />
=== Section 4, involves the craving of the blades and the welding of the base for the turbine generator. ===<br />
<br />
4.1 Making the blades <br />
The drawknife is useful for thicker chunks of wood, and for cutting down into a hollow. <br />
It can make a nice smooth job of the root of the blade, whereas the plane will work better <br />
where you need a very straight finish.<br />
<br />
'''Marking the stations.'''<br />
<br />
Place the blade with its best edge toward you on its upper surface. This will actually<br />
become the back or ‘downwind’ side of the finished blade.<br />
(Most of the front or windward side is to be cut off, so defects on this underneath side<br />
are not important.)<br />
<br />
The root of the blade will be on your right, the tip at the left, 1000 mm from the root<br />
(near the left end).<br />
<br />
Measure from the root, and mark four stations.<br />
Station A at 75mm<br />
Station B at 150 mm<br />
Station C at 500 mm<br />
The Tip at 1000 mm.<br />
<br />
<br />
At each station draw a line right around the workpiece using a square.<br />
<br />
[[File:01tur.jpeg|400px]]<br />
<br />
<br />
'''Tapering the blade'''<br />
The width of the blade tapers down from full size at station C to 55 mm wide at the<br />
tip. Mark the 55 mm tip width, measuring from the leading edge side. Draw a line<br />
though your mark to the trailing edge side at C station and cut off a triangular piece so<br />
as to achieve the correct tapered shape for the blade. Any knots in the triangular<br />
off cut do not matter as this piece is discarded. Try to make this a "square" cut,<br />
perpendicular to the back surface of the blade.<br />
You can do this with a circular saw, or by cross-cutting and shaving as described<br />
above.<br />
<br />
<br />
[[File:02tur.jpeg|400px]]<br />
<br />
'''Marking the leading and trailing edges'''<br />
The next step is to cut the windward face of the blade. This face is defined by the<br />
leading and trailing edge lines of the blade. These lines need to be marked with<br />
reference to the back face of the wood which has been uppermost in the previous<br />
operation.<br />
<br />
Turn the wood over. Start by drawing two diagonal lines between stations A and B<br />
on the front or windward side (see below). One is on the front face and the other on<br />
the trailing edge which is now toward you. <br />
<br />
[[File:03tur.jpeg|400px]]<br />
<br />
<br />
Now draw the leading edge line as shown below, <br />
from station B, down to 16mm(from the back) at station C, then continuing to the tip at<br />
7mm from the back.<br />
<br />
[[File:04tur.jpeg|400px]]<br />
<br />
<br />
(This drawing does not show the extra bit beyond the tip which may remain <br />
in your actual workpiece.)<br />
<br />
Measurements are summarised in this table below. Heights are from the back of the<br />
blade which will then rest on the bench. Remove the wood above this height. "Full"<br />
refers to the full thickness of the original piece of wood you are using.<br />
<br />
<br />
<br />
[[File:05tur.jpeg|400px]]<br />
<br />
<br />
'''The trailing''' <br />
The trailing edge line starts at the bottom of the diagonal line at station B, and <br />
rises to 5mm at C, continuing at 5 mm to the tip. This view below shows the wood <br />
already removed between the two lines to form the windward face of the blade.<br />
<br />
<br />
[[File:06tur.png|400px]]<br />
<br />
<br />
Carve this flat windward face between the 2 lines. Take care that the edges are<br />
straight, following the lines. The best tool to use for finishing the outer part of the<br />
blade is a plane, to give a smooth, straight finish. You may need to work the plane at<br />
45 degrees to the workpiece, sliding partly sideways, to form the hollow shape at<br />
station C.<br />
<br />
This step is completed when you can place a ruler across the face between the leading<br />
and trailing edge lines and there is no ‘hump’ in the middle. Fill any chips or small<br />
hollows with wood filler. If there are any serious errors, or large knots that weaken<br />
the blade then it may have to be discarded.<br />
Check the “drop” using a level as a reference. Clamp the wood so that the root part<br />
sits level, and measure the difference in level between the leading and trailing edges.<br />
The difference or “drop” should be 11 mm at the 500 mm mid-point, and 2 mm at the<br />
tip.<br />

"Pedagoxías do vento e das estrelas. As relacións sociais ás que (nunca estabamos destinados a) sobrevivir, tamén vivimos nos nosos corpos dolorosamente, e Audre Lorde non está aquí para lembrarnos esta lección, salvo na medida en que está presente no vento pedagóxico.<br />
Pero o vento é o noso mestre (74). -Alexis Pauline Gumbs "<br />
<br />
O principal obxectivo deste evento é prototipar un xerador eólico a pequena escala para camiñar xuntos cara á autosuficiencia neste campo.<br />
Temos o pracer de comunicarvos que do 16 ao 23 de outubro Biotranslab de Pin e The Foundry establecen unha colaboración para levar a cabo o evento Eco (i) Logic Queer Energy harvesting. O proxecto é posible grazas ao apoio de GOSH, unha rede para desenvolver e difundir proxectos baseados en hardware de código aberto para a ciencia.<br />
<br />
EcoLoxicas Queer para a captación de enerxía eolica. <br />
O evento ten como obxectivo abordar a falta de mulleres, queer, trans e diversidade nos ámbitos tecnolóxicos en xeral e do hacking máis concretamente. Pero aínda máis, pretende crear unha comunidade que avalía criticamente as narrativas hexemónicas arredor das tecnoloxías, os aspectos de modernidade dos seus supostos occidentais subliñados e as súas inflexións capitalistas inherentes, entre outros.<br />
O obxectivo principal do evento é desenvolver kits que se centren na interacción co medio natural no ámbito da enerxía.. o obxectivo principal pasa pola captación de enerxía do medio natural, a través dos aeroxeradores. Estes kits de enerxía serán escalables e poderán utilizarse tanto como material pedagóxico como para instalar centrais eléctricas específicas do sitio en diferentes sitios tamén. Este traballo ten un compoñente contrainfraestrutural: unha posible consecuencia sería capacitar ás persoas para xerar a súa propia enerxía en lugar de depender de grandes empresas e moitas veces extractivas.<br />

''Pedagogies of the Wind and Stars. The social relations that we (were never meant to) survive, also live in our bodies painfully, and Audre Lorde is not here to remind us of this lesson herself, except in as much that she is present in the pedagogical wind. But wind is our teacher (74). -Alexis Pauline Gumbs'' from the book Mapping Queer Space(s) of Praxis and Pedagogy <br />
Editors: Elizabeth McNeil, James E. Wermers, Joshua O. Lunn'' <br />
<br />
We have the pleasure to communicate you that from 16 to 29 of October Pin Biotranslab, Casa do Río e The Foundry establishes a collaboration to run the event Eco (i) Logic Queer Energy harvesting. The project is possible thanks to the support of GOSH, an network for develop and disseminate projects based on Open Source hardware for Science.<br />
<br />
'''Eco (i) Logic Queer Energy harvesting''' <br />
The event aims at addressing the lack of women, queer, trans and diversity in technological fields in general and hacking more specifically. But even more so, it aims at creating a community that critically assesses the hegemonic narratives around technologies, the modernity aspects of its underlining Western assumptions and its inherent capitalist inflections, among others.<br />
The main purpose of the event is to develop kits that focus on interacting with the natural environment on the field of energy.. the main objective lies on harvesting energy of the natural environment, through wind turbines. These power kits will be scalable and can be used both as pedagogical material and to set up site-specific power plants in different sites as well. There is a counter-infrastructural component to this work: one possible consequence would be to empower people to generate their own energy instead of relying on large and often extractive companies.<br />
<br />
== Introduction and values of the process ==<br />
<br />
Here starts the documentation of the long process of the prototyping the Hugh Piggott The Piggott Turbine – Wind Empowerment model of an Open source wind turbine. We were changing a bit the goals of the event from developing small kits to going to build the real 2m size wind turbine to provide energy to the rural regional areas we were working on. In that specific event we were working at The Foundry a nice project and association that we have settled on the north part of GaliZA into the Northwest of Spain.<br />
<br />
During the event many things have been activated between the doers and the visitors; In general It was a wondering experience full of new things to study, learn, doing and understand together. <br />
<br />
We chose this model because It was full of layers of interest on the levels of learning, understanding and making it, here some levels mixed up with layers: <br />
<br />
first to all is one of the ones that is '''open source''' or at least has the option to access the full documentation.<br />
<br />
really '''rich on the pedagogical level''', we were really learning through the complete building of the generator itself, about many topics as :<br />
* electromagnetism<br />
* mathematics<br />
* geometry<br />
* electronics<br />
* AC-DC<br />
* welding<br />
* wood carving<br />
* sculpting and casting pieces<br />
and much more that was reaching through the nice process of reading, learning and building together.<br />
<br />
== Glossary ==<br />
<br />
* '''AC-'''Alternating current as produced by the alternator. All thread - USA word for 'threaded' or 'spun' rod or studding<br />
* '''Brake switch''' - A switch used to short-circuit the wires from the alternator so that it stops.<br />
* '''Catalyst''' - A chemical used to make the polyester resin set solid. Catalyst reacts with 'accelerator' already present in the resin mix. <br />
The heat of reaction sets the polyester.<br />
* '''Cavalier''' - A make of car. The cavalier in the UK is not the same as the Cavalier in the USA but both have useful wheel hubs.<br />
* '''DC - direct current''' with a positive and a negative side, as in battery circuits.<br />
* '''Diameter''' - The distance from one side of a circle to another. The width of a disk right across the middle.<br />
* '''Phase''' - The timing of the cyclical alternation of voltage in a circuit. Different phases will peak at different times.<br />
* '''Polyester''' - A type of resin used in fibreglass work. Also suitable for making castings.<br />
* '''Power''' - the rate of delivery of energy<br />
* '''Rectifier''' - A semiconductor device that turns AC into DC for charging the battery.<br />
* '''Root''' - The widest part of the blade near to the hub at the center of the rotor.<br />
* '''Rotor''' - A rotating part. Magnet rotors are the steel diskscarrying the magnets past the stator. Rotor blades are the 'propeller' <br />
driven by the wind and driving the magnet rotors.<br />
* '''Soldering''' - A method for making electrical connections between wires using a hot 'iron' and coating everything with molten solder.<br />
* '''Drag''' - A force exerted by the wind on an object. Drag is parallel to the wind direction at the object. (see Lift) <br />
* '''Stator''' - An assembly of coils embedded in a slab of resin to form part of the alternator. The magnets induce a voltage in the coils and we can use this to charge a battery.<br />
* '''Drop''' - Used here to describe a certain measurement of the shape of a windmill blade. The 'drop' affects the angle of<br />
the blade to the wind. Styrene monomer - A nasty smelling solvent in the polyester resin mix.<br />
* '''Flux''' - The 'stuff' of magnetism. Similar to 'current' in electricity. It can be visualized as 'lines' coming out of one pole and <br />
returning to the other.<br />
* '''Furling''' - A protective action that reduces exposure to violent winds by facing the blades away from them.<br />
* '''Jig''' - A device used to hold the magnets in place before setting them in resin.<br />
* '''Leading edge''' - The edge of a blade that would strike an object placed in its path as the rotor spins.<br />
* '''Lift''' - A force exerted by the wind on an object. Lift is at right angles to the wind direction at the object. (see Drag)<br />
* '''Mold''' - A shaped container in which resin castings are formed. The mould can be discarded after the casting has set.<br />
* '''Multimeter''' - A versatile electrical test instrument, used to measure voltage, current and other parameters.<br />
* '''Neodymium''' - The name given to a type of permanent magnet containing neodymium, iron and boron. These magnets are very strong and <br />
getting cheaper all the time.<br />
* '''Offset''' - An eccentric position, off centre.<br />
* '''Talcum powder'''- A cheap filler powder used to thicken the resin and slow its reaction (prevent it overheating).<br />
* '''Tail''' - A projecting vane mounted on a boom at the back ofthe windmill used to steer it into or out of the wind automatically.<br />
* '''Tap''' - a tool for making thread inside holes so you can fit a screw into the hole.<br />
* '''Thrust''' - The force of the wind pushing the machine backwards.<br />
* '''Tower''' - The mast supporting the windmill.<br />
* '''Trailing edge''' - The blade edge furthest from the leading edge. The trailing edge is sharpened, so as to release the passing <br />
air without turbulence.<br />
* '''Wedges''' - Tapered pieces of wood used to build up the blade thickness and increase its angle to the wind near the root.<br />
* '''Work-piece''' - The piece of wood or metal being shaped in the workshop.<br />
* '''Yaw bearing''' - the swivel at the top of the tower on which the windmill is mounted. The yaw bearing allows the windmill to face the wind.<br />

== The space == <br />
<br />
=== The Foundry ===<br />
The Foundry is a non-profit organization based in a previously abandoned GaliZA village. It functions both as a residency and as a project space. It subscribes to the ideals of self-organization, and has the following three objectives:<br />
1. Organizing activities in the field of the arts, science and humanities outside of traditional institutions, focusing on critical discourse.<br />
2. Promoting the exchange of ideas and intellectual collaboration outside of the constraints imposed by state and market.<br />
3. Increasing self-sufficiency, sustainability, and an awareness of the environment using appropriate technology and open source as main resources.<br />
Taking into account this context, our aim is to reinforce the capacity to generate networks flowing from rural to urban context supporting non hierarchy and democratic exchanges of knowledge and practices that can enable new and sustainable models within rural contexts. According to that we consider that the new trans-disciplinary creative sectors in which we are entangled can have a huge and positive impact in the creation of this new paradigm. https://bravosfoundry.com/<br />
Aside from that, there is thematic focus on transdisciplinarity, transfeminism and post-humanism. While this focus is not adequately grasped by identity-political categories like race or gender, we hope it leads to the subversion of hegemonic structures inscribed in the binarisms upholding many of these categories. Our interest lies in the development of tools and technologies that subvert contemporary structures of domination, exploitation and marginalization, not in those that reproduce it.<br />
We seek to develop a more sustainable environment by opening up our practices based on a free culture framework, generating networks and interest around them, enabling a flow of exchange of innovation across creative sectors focusing on revaluation of rural contexts and its knowledge heritage.<br />

=== '''Section 2, involves the construction of '''the alternator''' parts using the devices from the section 1.''' ===<br />
<br />
'''Alternator'''<br />
Each magnet rotor is a steel disk with 12 magnets placed on it and set in resin. The magnets are each 50 x 50 x 20 mm, and they only just fit on the disk. The idea is to achieve the maximum amount of flux in a given space.<br />
The turbine runs at 650 rpm for 400W output, so the centrifugal force on the magnets is 60 times the force of gravity. To prevent them flying off, the resin casting needs to be reinforced. Stainless steel wire rope is placed around the outside of the magnets to hold the casting together at high rpm. We use stainless because it is non-magnetic, or at least less magnetic than normal steel wire rope. <br />
<br />
You will wind the coils that produce the output power and cast them in resin to form a stator between the two magnet rotors. Photos of the final pieces here <br />

[[File:prod05.jpg|300px]] <br />
<br />
Step - Generator, rotor: Preparation of the wheel hub.<br />
<br />
[[File:frame10.jpg|300px]]<br />
<br />
'''The wheel hub'''<br />
<br />
You can find a used car rear wheel hub (Golf, Toyota, etc.) that has a simple way to<br />
attach the axle, or alternatively buy a trailer hubs online new at low cost.<br />
PCD or ‘pitch circle diameter' is the diameter of the circle of the hole pattern in the<br />
hub, and usually this will be 100mm for a car wheel hub, or 4 inches for a trailer hub.<br />
Car hubs may have a brake-drum that you do not need. This can be removed using a<br />
cutting disk on a grinder. The simplest approach is to make four straight cuts around<br />
the four holes in the front, leaving a square surface to which you mount the magnet<br />
rotors. These photos show a golf rear wheel hub – first the brake-drum being cut, and<br />
then the finished hub after cutting off the drum.A typical rear wheel car hub with a <br />
flange on the back end of the stub shaft that can reused to mount it.<br />
Trailer hubs on the other hand are rather basic quality, and the bearings may be too<br />
cheap for long term use, but they are readily available items that can be purchased<br />
online as new. The drawings below (from autow.com) show a typical hub and stub<br />
axle which are bought separately.<br />
You need to be ready to replace the bearings with a named brand (such as SKF). It’s<br />
easy to replace the inner cones and rollers but the outer shells need to be knocked<br />
gently out of the hub with a suitable drift. Keep them straight by tapping evenly on<br />
opposite sides, and take care not to scratch the seating.<br />

Step - Generator, rotor: PreStep<br />
<br />
=== Section 4, involves the craving of the blades and the welding of the base for the turbine generator. ===<br />
<br />
4.1 Making the blades <br />
The drawknife is useful for thicker chunks of wood, and for cutting down into a hollow. <br />
It can make a nice smooth job of the root of the blade, whereas the plane will work better <br />
where you need a very straight finish.<br />
<br />
'''Marking the stations.'''<br />
<br />
Place the blade with its best edge toward you on its upper surface. This will actually<br />
become the back or ‘downwind’ side of the finished blade.<br />
(Most of the front or windward side is to be cut off, so defects on this underneath side<br />
are not important.)<br />
<br />
The root of the blade will be on your right, the tip at the left, 1000 mm from the root<br />
(near the left end).<br />
<br />
Measure from the root, and mark four stations.<br />
Station A at 75mm<br />
Station B at 150 mm<br />
Station C at 500 mm<br />
The Tip at 1000 mm.<br />
<br />
<br />
At each station draw a line right around the workpiece using a square.<br />
<br />
[[File:01tur.jpeg|400px]]<br />
<br />
<br />
'''Tapering the blade'''<br />
The width of the blade tapers down from full size at station C to 55 mm wide at the<br />
tip. Mark the 55 mm tip width, measuring from the leading edge side. Draw a line<br />
though your mark to the trailing edge side at C station and cut off a triangular piece so<br />
as to achieve the correct tapered shape for the blade. Any knots in the triangular<br />
off cut do not matter as this piece is discarded. Try to make this a "square" cut,<br />
perpendicular to the back surface of the blade.<br />
You can do this with a circular saw, or by cross-cutting and shaving as described<br />
above.<br />
<br />
<br />
[[File:02tur.jpeg|400px]]<br />
<br />
'''Marking the leading and trailing edges'''<br />
The next step is to cut the windward face of the blade. This face is defined by the<br />
leading and trailing edge lines of the blade. These lines need to be marked with<br />
reference to the back face of the wood which has been uppermost in the previous<br />
operation.<br />
<br />
Turn the wood over. Start by drawing two diagonal lines between stations A and B<br />
on the front or windward side (see below). One is on the front face and the other on<br />
the trailing edge which is now toward you. <br />
<br />
[[File:03tur.jpeg|400px]]<br />
<br />
<br />
Now draw the leading edge line as shown below, <br />
from station B, down to 16mm(from the back) at station C, then continuing to the tip at<br />
7mm from the back.<br />
<br />
[[File:04tur.jpeg|400px]]<br />
<br />
<br />
(This drawing does not show the extra bit beyond the tip which may remain <br />
in your actual workpiece.)<br />
<br />
Measurements are summarised in this table below. Heights are from the back of the<br />
blade which will then rest on the bench. Remove the wood above this height. "Full"<br />
refers to the full thickness of the original piece of wood you are using.<br />
<br />
<br />
<br />
[[File:05tur.jpeg|400px]]<br />
<br />
<br />
'''The trailing''' <br />
The trailing edge line starts at the bottom of the diagonal line at station B, and <br />
rises to 5mm at C, continuing at 5 mm to the tip. This view below shows the wood <br />
already removed between the two lines to form the windward face of the blade.<br />
<br />
<br />
[[File:06tur.png|400px]]<br />
<br />
<br />
Carve this flat windward face between the 2 lines. Take care that the edges are<br />
straight, following the lines. The best tool to use for finishing the outer part of the<br />
blade is a plane, to give a smooth, straight finish. You may need to work the plane at<br />
45 degrees to the workpiece, sliding partly sideways, to form the hollow shape at<br />
station C.<br />
<br />
This step is completed when you can place a ruler across the face between the leading<br />
and trailing edge lines and there is no ‘hump’ in the middle. Fill any chips or small<br />
hollows with wood filler. If there are any serious errors, or large knots that weaken<br />
the blade then it may have to be discarded.<br />
Check the “drop” using a level as a reference. Clamp the wood so that the root part<br />
sits level, and measure the difference in level between the leading and trailing edges.<br />
The difference or “drop” should be 11 mm at the 500 mm mid-point, and 2 mm at the<br />
tip.<br />

"Pedagoxías do vento e das estrelas. As relacións sociais ás que (nunca estabamos destinados a) sobrevivir, tamén vivimos nos nosos corpos dolorosamente, e Audre Lorde non está aquí para lembrarnos esta lección, salvo na medida en que está presente no vento pedagóxico.<br />
Pero o vento é o noso mestre (74). -Alexis Pauline Gumbs "<br />
<br />
O principal obxectivo deste evento é prototipar un xerador eólico a pequena escala para camiñar xuntos cara á autosuficiencia neste campo.<br />
Temos o pracer de comunicarvos que do 16 ao 23 de outubro Biotranslab de Pin e The Foundry establecen unha colaboración para levar a cabo o evento Eco (i) Logic Queer Energy harvesting. O proxecto é posible grazas ao apoio de GOSH, unha rede para desenvolver e difundir proxectos baseados en hardware de código aberto para a ciencia.<br />
<br />
EcoLoxicas Queer para a captación de enerxía eolica. <br />
O evento ten como obxectivo abordar a falta de mulleres, queer, trans e diversidade nos ámbitos tecnolóxicos en xeral e do hacking máis concretamente. Pero aínda máis, pretende crear unha comunidade que avalía criticamente as narrativas hexemónicas arredor das tecnoloxías, os aspectos de modernidade dos seus supostos occidentais subliñados e as súas inflexións capitalistas inherentes, entre outros.<br />
O obxectivo principal do evento é desenvolver kits que se centren na interacción co medio natural no ámbito da enerxía.. o obxectivo principal pasa pola captación de enerxía do medio natural, a través dos aeroxeradores. Estes kits de enerxía serán escalables e poderán utilizarse tanto como material pedagóxico como para instalar centrais eléctricas específicas do sitio en diferentes sitios tamén. Este traballo ten un compoñente contrainfraestrutural: unha posible consecuencia sería capacitar ás persoas para xerar a súa propia enerxía en lugar de depender de grandes empresas e moitas veces extractivas.<br />

''Pedagogies of the Wind and Stars. The social relations that we (were never meant to) survive, also live in our bodies painfully, and Audre Lorde is not here to remind us of this lesson herself, except in as much that she is present in the pedagogical wind. But wind is our teacher (74). -Alexis Pauline Gumbs'' from the book Mapping Queer Space(s) of Praxis and Pedagogy <br />
Editors: Elizabeth McNeil, James E. Wermers, Joshua O. Lunn'' <br />
<br />
We have the pleasure to communicate you that from 16 to 29 of October Pin Biotranslab, Casa do Río e The Foundry establishes a collaboration to run the event Eco (i) Logic Queer Energy harvesting. The project is possible thanks to the support of GOSH, an network for develop and disseminate projects based on Open Source hardware for Science.<br />
<br />
'''Eco (i) Logic Queer Energy harvesting''' <br />
The event aims at addressing the lack of women, queer, trans and diversity in technological fields in general and hacking more specifically. But even more so, it aims at creating a community that critically assesses the hegemonic narratives around technologies, the modernity aspects of its underlining Western assumptions and its inherent capitalist inflections, among others.<br />
The main purpose of the event is to develop kits that focus on interacting with the natural environment on the field of energy.. the main objective lies on harvesting energy of the natural environment, through wind turbines. These power kits will be scalable and can be used both as pedagogical material and to set up site-specific power plants in different sites as well. There is a counter-infrastructural component to this work: one possible consequence would be to empower people to generate their own energy instead of relying on large and often extractive companies.<br />
<br />
== Introduction and values of the process ==<br />
<br />
Here starts the documentation of the long process of the prototyping the Hugh Piggott The Piggott Turbine – Wind Empowerment model of an Open source wind turbine. We were changing a bit the goals of the event from developing small kits to going to build the real 2m size wind turbine to provide energy to the rural regional areas we were working on. In that specific event we were working at The Foundry a nice project and association that we have settled on the north part of GaliZA into the Northwest of Spain.<br />
<br />
During the event many things have been activated between the doers and the visitors; In general It was a wondering experience full of new things to study, learn, doing and understand together. <br />
<br />
We chose this model because It was full of layers of interest on the levels of learning, understanding and making it, here some levels mixed up with layers: <br />
<br />
first to all is one of the ones that is '''open source''' or at least has the option to access the full documentation.<br />
<br />
really '''rich on the pedagogical level''', we were really learning through the complete building of the generator itself, about many topics as :<br />
* electromagnetism<br />
* mathematics<br />
* geometry<br />
* electronics<br />
* AC-DC<br />
* welding<br />
* wood carving<br />
* sculpting and casting pieces<br />
and much more that was reaching through the nice process of reading, learning and building together.<br />
<br />
== Glossary ==<br />
<br />
* '''AC-'''Alternating current as produced by the alternator. All thread - USA word for 'threaded' or 'spun' rod or studding<br />
* '''Brake switch''' - A switch used to short-circuit the wires from the alternator so that it stops.<br />
* '''Catalyst''' - A chemical used to make the polyester resin set solid. Catalyst reacts with 'accelerator' already present in the resin mix. <br />
The heat of reaction sets the polyester.<br />
* '''Cavalier''' - A make of car. The cavalier in the UK is not the same as the Cavalier in the USA but both have useful wheel hubs.<br />
* '''DC - direct current''' with a positive and a negative side, as in battery circuits.<br />
* '''Diameter''' - The distance from one side of a circle to another. The width of a disk right across the middle.<br />
* '''Phase''' - The timing of the cyclical alternation of voltage in a circuit. Different phases will peak at different times.<br />
* '''Polyester''' - A type of resin used in fibreglass work. Also suitable for making castings.<br />
* '''Power''' - the rate of delivery of energy<br />
* '''Rectifier''' - A semiconductor device that turns AC into DC for charging the battery.<br />
* '''Root''' - The widest part of the blade near to the hub at the center of the rotor.<br />
* '''Rotor''' - A rotating part. Magnet rotors are the steel diskscarrying the magnets past the stator. Rotor blades are the 'propeller' <br />
driven by the wind and driving the magnet rotors.<br />
* '''Soldering''' - A method for making electrical connections between wires using a hot 'iron' and coating everything with molten solder.<br />
* '''Drag''' - A force exerted by the wind on an object. Drag is parallel to the wind direction at the object. (see Lift) <br />
* '''Stator''' - An assembly of coils embedded in a slab of resin to form part of the alternator. The magnets induce a voltage in the coils and we can use this to charge a battery.<br />
* '''Drop''' - Used here to describe a certain measurement of the shape of a windmill blade. The 'drop' affects the angle of<br />
the blade to the wind. Styrene monomer - A nasty smelling solvent in the polyester resin mix.<br />
* '''Flux''' - The 'stuff' of magnetism. Similar to 'current' in electricity. It can be visualized as 'lines' coming out of one pole and <br />
returning to the other.<br />
* '''Furling''' - A protective action that reduces exposure to violent winds by facing the blades away from them.<br />
* '''Jig''' - A device used to hold the magnets in place before setting them in resin.<br />
* '''Leading edge''' - The edge of a blade that would strike an object placed in its path as the rotor spins.<br />
* '''Lift''' - A force exerted by the wind on an object. Lift is at right angles to the wind direction at the object. (see Drag)<br />
* '''Mold''' - A shaped container in which resin castings are formed. The mould can be discarded after the casting has set.<br />
* '''Multimeter''' - A versatile electrical test instrument, used to measure voltage, current and other parameters.<br />
* '''Neodymium''' - The name given to a type of permanent magnet containing neodymium, iron and boron. These magnets are very strong and <br />
getting cheaper all the time.<br />
* '''Offset''' - An eccentric position, off centre.<br />
* '''Talcum powder'''- A cheap filler powder used to thicken the resin and slow its reaction (prevent it overheating).<br />
* '''Tail''' - A projecting vane mounted on a boom at the back ofthe windmill used to steer it into or out of the wind automatically.<br />
* '''Tap''' - a tool for making thread inside holes so you can fit a screw into the hole.<br />
* '''Thrust''' - The force of the wind pushing the machine backwards.<br />
* '''Tower''' - The mast supporting the windmill.<br />
* '''Trailing edge''' - The blade edge furthest from the leading edge. The trailing edge is sharpened, so as to release the passing <br />
air without turbulence.<br />
* '''Wedges''' - Tapered pieces of wood used to build up the blade thickness and increase its angle to the wind near the root.<br />
* '''Work-piece''' - The piece of wood or metal being shaped in the workshop.<br />
* '''Yaw bearing''' - the swivel at the top of the tower on which the windmill is mounted. The yaw bearing allows the windmill to face the wind.<br />

== The space == <br />
<br />
=== The Foundry ===<br />
The Foundry is a non-profit organization based in a previously abandoned GaliZA village. It functions both as a residency and as a project space. It subscribes to the ideals of self-organization, and has the following three objectives:<br />
1. Organizing activities in the field of the arts, science and humanities outside of traditional institutions, focusing on critical discourse.<br />
2. Promoting the exchange of ideas and intellectual collaboration outside of the constraints imposed by state and market.<br />
3. Increasing self-sufficiency, sustainability, and an awareness of the environment using appropriate technology and open source as main resources.<br />
Taking into account this context, our aim is to reinforce the capacity to generate networks flowing from rural to urban context supporting non hierarchy and democratic exchanges of knowledge and practices that can enable new and sustainable models within rural contexts. According to that we consider that the new trans-disciplinary creative sectors in which we are entangled can have a huge and positive impact in the creation of this new paradigm. https://bravosfoundry.com/<br />
Aside from that, there is thematic focus on transdisciplinarity, transfeminism and post-humanism. While this focus is not adequately grasped by identity-political categories like race or gender, we hope it leads to the subversion of hegemonic structures inscribed in the binarisms upholding many of these categories. Our interest lies in the development of tools and technologies that subvert contemporary structures of domination, exploitation and marginalization, not in those that reproduce it.<br />
We seek to develop a more sustainable environment by opening up our practices based on a free culture framework, generating networks and interest around them, enabling a flow of exchange of innovation across creative sectors focusing on revaluation of rural contexts and its knowledge heritage.<br />

=== '''Section 2, involves the construction of '''the alternator''' parts using the devices from the section 1.''' ===<br />
<br />
'''Alternator'''<br />
Each magnet rotor is a steel disk with 12 magnets placed on it and set in resin. The magnets are each 50 x 50 x 20 mm, and they only just fit on the disk. The idea is to achieve the maximum amount of flux in a given space.<br />
The turbine runs at 650 rpm for 400W output, so the centrifugal force on the magnets is 60 times the force of gravity. To prevent them flying off, the resin casting needs to be reinforced. Stainless steel wire rope is placed around the outside of the magnets to hold the casting together at high rpm. We use stainless because it is non-magnetic, or at least less magnetic than normal steel wire rope. <br />
<br />
You will wind the coils that produce the output power and cast them in resin to form a stator between the two magnet rotors. Photos of the final pieces here <br />

[[File:prod05.jpg|300px]] <br />
<br />
Step - Generator, rotor: Preparation of the wheel hub.<br />
<br />
[[File:frame10.jpg|300px]]<br />
<br />
'''The wheel hub'''<br />
<br />
You can find a used car rear wheel hub (Golf, Toyota, etc.) that has a simple way to<br />
attach the axle, or alternatively buy a trailer hubs online new at low cost.<br />
PCD or ‘pitch circle diameter' is the diameter of the circle of the hole pattern in the<br />
hub, and usually this will be 100mm for a car wheel hub, or 4 inches for a trailer hub.<br />
Car hubs may have a brake-drum that you do not need. This can be removed using a<br />
cutting disk on a grinder. The simplest approach is to make four straight cuts around<br />
the four holes in the front, leaving a square surface to which you mount the magnet<br />
rotors. These photos show a golf rear wheel hub – first the brake-drum being cut, and<br />
then the finished hub after cutting off the drum.A typical rear wheel car hub with a <br />
flange on the back end of the stub shaft that can reused to mount it.<br />
Trailer hubs on the other hand are rather basic quality, and the bearings may be too<br />
cheap for long term use, but they are readily available items that can be purchased<br />
online as new. The drawings below (from autow.com) show a typical hub and stub<br />
axle which are bought separately.<br />
You need to be ready to replace the bearings with a named brand (such as SKF). It’s<br />
easy to replace the inner cones and rollers but the outer shells need to be knocked<br />
gently out of the hub with a suitable drift. Keep them straight by tapping evenly on<br />
opposite sides, and take care not to scratch the seating.<br />

Step - Generator, rotor: PreStep<br />
<br />
=== Section 4, involves the craving of the blades and the welding of the base for the turbine generator. ===<br />
<br />
4.1 Making the blades <br />
The drawknife is useful for thicker chunks of wood, and for cutting down into a hollow. <br />
It can make a nice smooth job of the root of the blade, whereas the plane will work better <br />
where you need a very straight finish.<br />
<br />
'''Marking the stations.'''<br />
<br />
Place the blade with its best edge toward you on its upper surface. This will actually<br />
become the back or ‘downwind’ side of the finished blade.<br />
(Most of the front or windward side is to be cut off, so defects on this underneath side<br />
are not important.)<br />
<br />
The root of the blade will be on your right, the tip at the left, 1000 mm from the root<br />
(near the left end).<br />
<br />
Measure from the root, and mark four stations.<br />
Station A at 75mm<br />
Station B at 150 mm<br />
Station C at 500 mm<br />
The Tip at 1000 mm.<br />
<br />
<br />
At each station draw a line right around the workpiece using a square.<br />
<br />
[[File:01tur.jpeg|400px]]<br />
<br />
<br />
'''Tapering the blade'''<br />
The width of the blade tapers down from full size at station C to 55 mm wide at the<br />
tip. Mark the 55 mm tip width, measuring from the leading edge side. Draw a line<br />
though your mark to the trailing edge side at C station and cut off a triangular piece so<br />
as to achieve the correct tapered shape for the blade. Any knots in the triangular<br />
off cut do not matter as this piece is discarded. Try to make this a "square" cut,<br />
perpendicular to the back surface of the blade.<br />
You can do this with a circular saw, or by cross-cutting and shaving as described<br />
above.<br />
<br />
<br />
[[File:02tur.jpeg|400px]]<br />
<br />
'''Marking the leading and trailing edges'''<br />
The next step is to cut the windward face of the blade. This face is defined by the<br />
leading and trailing edge lines of the blade. These lines need to be marked with<br />
reference to the back face of the wood which has been uppermost in the previous<br />
operation.<br />
<br />
Turn the wood over. Start by drawing two diagonal lines between stations A and B<br />
on the front or windward side (see below). One is on the front face and the other on<br />
the trailing edge which is now toward you. <br />
<br />
[[File:03tur.jpeg|400px]]<br />
<br />
<br />
Now draw the leading edge line as shown below, <br />
from station B, down to 16mm(from the back) at station C, then continuing to the tip at<br />
7mm from the back.<br />
<br />
[[File:04tur.jpeg|400px]]<br />
<br />
<br />
(This drawing does not show the extra bit beyond the tip which may remain <br />
in your actual workpiece.)<br />
<br />
Measurements are summarised in this table below. Heights are from the back of the<br />
blade which will then rest on the bench. Remove the wood above this height. "Full"<br />
refers to the full thickness of the original piece of wood you are using.<br />
<br />
<br />
<br />
[[File:05tur.jpeg|400px]]<br />
<br />
<br />
'''The trailing''' <br />
The trailing edge line starts at the bottom of the diagonal line at station B, and <br />
rises to 5mm at C, continuing at 5 mm to the tip. This view below shows the wood <br />
already removed between the two lines to form the windward face of the blade.<br />
<br />
<br />
[[File:06tur.png|400px]]<br />
<br />
<br />
Carve this flat windward face between the 2 lines. Take care that the edges are<br />
straight, following the lines. The best tool to use for finishing the outer part of the<br />
blade is a plane, to give a smooth, straight finish. You may need to work the plane at<br />
45 degrees to the workpiece, sliding partly sideways, to form the hollow shape at<br />
station C.<br />
<br />
This step is completed when you can place a ruler across the face between the leading<br />
and trailing edge lines and there is no ‘hump’ in the middle. Fill any chips or small<br />
hollows with wood filler. If there are any serious errors, or large knots that weaken<br />
the blade then it may have to be discarded.<br />
Check the “drop” using a level as a reference. Clamp the wood so that the root part<br />
sits level, and measure the difference in level between the leading and trailing edges.<br />
The difference or “drop” should be 11 mm at the 500 mm mid-point, and 2 mm at the<br />
tip.<br />

"Pedagoxías do vento e das estrelas. As relacións sociais ás que (nunca estabamos destinados a) sobrevivir, tamén vivimos nos nosos corpos dolorosamente, e Audre Lorde non está aquí para lembrarnos esta lección, salvo na medida en que está presente no vento pedagóxico.<br />
Pero o vento é o noso mestre (74). -Alexis Pauline Gumbs "<br />
<br />
O principal obxectivo deste evento é prototipar un xerador eólico a pequena escala para camiñar xuntos cara á autosuficiencia neste campo.<br />
Temos o pracer de comunicarvos que do 16 ao 23 de outubro Biotranslab de Pin e The Foundry establecen unha colaboración para levar a cabo o evento Eco (i) Logic Queer Energy harvesting. O proxecto é posible grazas ao apoio de GOSH, unha rede para desenvolver e difundir proxectos baseados en hardware de código aberto para a ciencia.<br />
<br />
EcoLoxicas Queer para a captación de enerxía eolica. <br />
O evento ten como obxectivo abordar a falta de mulleres, queer, trans e diversidade nos ámbitos tecnolóxicos en xeral e do hacking máis concretamente. Pero aínda máis, pretende crear unha comunidade que avalía criticamente as narrativas hexemónicas arredor das tecnoloxías, os aspectos de modernidade dos seus supostos occidentais subliñados e as súas inflexións capitalistas inherentes, entre outros.<br />
O obxectivo principal do evento é desenvolver kits que se centren na interacción co medio natural no ámbito da enerxía.. o obxectivo principal pasa pola captación de enerxía do medio natural, a través dos aeroxeradores. Estes kits de enerxía serán escalables e poderán utilizarse tanto como material pedagóxico como para instalar centrais eléctricas específicas do sitio en diferentes sitios tamén. Este traballo ten un compoñente contrainfraestrutural: unha posible consecuencia sería capacitar ás persoas para xerar a súa propia enerxía en lugar de depender de grandes empresas e moitas veces extractivas.<br />

''Pedagogies of the Wind and Stars. The social relations that we (were never meant to) survive, also live in our bodies painfully, and Audre Lorde is not here to remind us of this lesson herself, except in as much that she is present in the pedagogical wind. But wind is our teacher (74). -Alexis Pauline Gumbs'' from the book Mapping Queer Space(s) of Praxis and Pedagogy <br />
Editors: Elizabeth McNeil, James E. Wermers, Joshua O. Lunn'' <br />
<br />
We have the pleasure to communicate you that from 16 to 29 of October Pin Biotranslab, Casa do Río e The Foundry establishes a collaboration to run the event Eco (i) Logic Queer Energy harvesting. The project is possible thanks to the support of GOSH, an network for develop and disseminate projects based on Open Source hardware for Science.<br />
<br />
'''Eco (i) Logic Queer Energy harvesting''' <br />
The event aims at addressing the lack of women, queer, trans and diversity in technological fields in general and hacking more specifically. But even more so, it aims at creating a community that critically assesses the hegemonic narratives around technologies, the modernity aspects of its underlining Western assumptions and its inherent capitalist inflections, among others.<br />
The main purpose of the event is to develop kits that focus on interacting with the natural environment on the field of energy.. the main objective lies on harvesting energy of the natural environment, through wind turbines. These power kits will be scalable and can be used both as pedagogical material and to set up site-specific power plants in different sites as well. There is a counter-infrastructural component to this work: one possible consequence would be to empower people to generate their own energy instead of relying on large and often extractive companies.<br />
<br />
== Introduction and values of the process ==<br />
<br />
Here starts the documentation of the long process of the prototyping the Hugh Piggott The Piggott Turbine – Wind Empowerment model of an Open source wind turbine. We were changing a bit the goals of the event from developing small kits to going to build the real 2m size wind turbine to provide energy to the rural regional areas we were working on. In that specific event we were working at The Foundry a nice project and association that we have settled on the north part of GaliZA into the Northwest of Spain.<br />
<br />
During the event many things have been activated between the doers and the visitors; In general It was a wondering experience full of new things to study, learn, doing and understand together. <br />
<br />
We chose this model because It was full of layers of interest on the levels of learning, understanding and making it, here some levels mixed up with layers: <br />
<br />
first to all is one of the ones that is '''open source''' or at least has the option to access the full documentation.<br />
<br />
really '''rich on the pedagogical level''', we were really learning through the complete building of the generator itself, about many topics as :<br />
* electromagnetism<br />
* mathematics<br />
* geometry<br />
* electronics<br />
* AC-DC<br />
* welding<br />
* wood carving<br />
* sculpting and casting pieces<br />
and much more that was reaching through the nice process of reading, learning and building together.<br />
<br />
== Glossary ==<br />
<br />
* '''AC-'''Alternating current as produced by the alternator. All thread - USA word for 'threaded' or 'spun' rod or studding<br />
* '''Brake switch''' - A switch used to short-circuit the wires from the alternator so that it stops.<br />
* '''Catalyst''' - A chemical used to make the polyester resin set solid. Catalyst reacts with 'accelerator' already present in the resin mix. <br />
The heat of reaction sets the polyester.<br />
* '''Cavalier''' - A make of car. The cavalier in the UK is not the same as the Cavalier in the USA but both have useful wheel hubs.<br />
* '''DC - direct current''' with a positive and a negative side, as in battery circuits.<br />
* '''Diameter''' - The distance from one side of a circle to another. The width of a disk right across the middle.<br />
* '''Phase''' - The timing of the cyclical alternation of voltage in a circuit. Different phases will peak at different times.<br />
* '''Polyester''' - A type of resin used in fibreglass work. Also suitable for making castings.<br />
* '''Power''' - the rate of delivery of energy<br />
* '''Rectifier''' - A semiconductor device that turns AC into DC for charging the battery.<br />
* '''Root''' - The widest part of the blade near to the hub at the center of the rotor.<br />
* '''Rotor''' - A rotating part. Magnet rotors are the steel diskscarrying the magnets past the stator. Rotor blades are the 'propeller' <br />
driven by the wind and driving the magnet rotors.<br />
* '''Soldering''' - A method for making electrical connections between wires using a hot 'iron' and coating everything with molten solder.<br />
* '''Drag''' - A force exerted by the wind on an object. Drag is parallel to the wind direction at the object. (see Lift) <br />
* '''Stator''' - An assembly of coils embedded in a slab of resin to form part of the alternator. The magnets induce a voltage in the coils and we can use this to charge a battery.<br />
* '''Drop''' - Used here to describe a certain measurement of the shape of a windmill blade. The 'drop' affects the angle of<br />
the blade to the wind. Styrene monomer - A nasty smelling solvent in the polyester resin mix.<br />
* '''Flux''' - The 'stuff' of magnetism. Similar to 'current' in electricity. It can be visualized as 'lines' coming out of one pole and <br />
returning to the other.<br />
* '''Furling''' - A protective action that reduces exposure to violent winds by facing the blades away from them.<br />
* '''Jig''' - A device used to hold the magnets in place before setting them in resin.<br />
* '''Leading edge''' - The edge of a blade that would strike an object placed in its path as the rotor spins.<br />
* '''Lift''' - A force exerted by the wind on an object. Lift is at right angles to the wind direction at the object. (see Drag)<br />
* '''Mold''' - A shaped container in which resin castings are formed. The mould can be discarded after the casting has set.<br />
* '''Multimeter''' - A versatile electrical test instrument, used to measure voltage, current and other parameters.<br />
* '''Neodymium''' - The name given to a type of permanent magnet containing neodymium, iron and boron. These magnets are very strong and <br />
getting cheaper all the time.<br />
* '''Offset''' - An eccentric position, off centre.<br />
* '''Talcum powder'''- A cheap filler powder used to thicken the resin and slow its reaction (prevent it overheating).<br />
* '''Tail''' - A projecting vane mounted on a boom at the back ofthe windmill used to steer it into or out of the wind automatically.<br />
* '''Tap''' - a tool for making thread inside holes so you can fit a screw into the hole.<br />
* '''Thrust''' - The force of the wind pushing the machine backwards.<br />
* '''Tower''' - The mast supporting the windmill.<br />
* '''Trailing edge''' - The blade edge furthest from the leading edge. The trailing edge is sharpened, so as to release the passing <br />
air without turbulence.<br />
* '''Wedges''' - Tapered pieces of wood used to build up the blade thickness and increase its angle to the wind near the root.<br />
* '''Work-piece''' - The piece of wood or metal being shaped in the workshop.<br />
* '''Yaw bearing''' - the swivel at the top of the tower on which the windmill is mounted. The yaw bearing allows the windmill to face the wind.<br />

== The space == <br />
<br />
=== The Foundry ===<br />
The Foundry is a non-profit organization based in a previously abandoned GaliZA village. It functions both as a residency and as a project space. It subscribes to the ideals of self-organization, and has the following three objectives:<br />
1. Organizing activities in the field of the arts, science and humanities outside of traditional institutions, focusing on critical discourse.<br />
2. Promoting the exchange of ideas and intellectual collaboration outside of the constraints imposed by state and market.<br />
3. Increasing self-sufficiency, sustainability, and an awareness of the environment using appropriate technology and open source as main resources.<br />
Taking into account this context, our aim is to reinforce the capacity to generate networks flowing from rural to urban context supporting non hierarchy and democratic exchanges of knowledge and practices that can enable new and sustainable models within rural contexts. According to that we consider that the new trans-disciplinary creative sectors in which we are entangled can have a huge and positive impact in the creation of this new paradigm. https://bravosfoundry.com/<br />
Aside from that, there is thematic focus on transdisciplinarity, transfeminism and post-humanism. While this focus is not adequately grasped by identity-political categories like race or gender, we hope it leads to the subversion of hegemonic structures inscribed in the binarisms upholding many of these categories. Our interest lies in the development of tools and technologies that subvert contemporary structures of domination, exploitation and marginalization, not in those that reproduce it.<br />
We seek to develop a more sustainable environment by opening up our practices based on a free culture framework, generating networks and interest around them, enabling a flow of exchange of innovation across creative sectors focusing on revaluation of rural contexts and its knowledge heritage.<br />

=== '''Section 2, involves the construction of '''the alternator''' parts using the devices from the section 1.''' ===<br />
<br />
'''Alternator'''<br />
Each magnet rotor is a steel disk with 12 magnets placed on it and set in resin. The magnets are each 50 x 50 x 20 mm, and they only just fit on the disk. The idea is to achieve the maximum amount of flux in a given space.<br />
The turbine runs at 650 rpm for 400W output, so the centrifugal force on the magnets is 60 times the force of gravity. To prevent them flying off, the resin casting needs to be reinforced. Stainless steel wire rope is placed around the outside of the magnets to hold the casting together at high rpm. We use stainless because it is non-magnetic, or at least less magnetic than normal steel wire rope. <br />
<br />
You will wind the coils that produce the output power and cast them in resin to form a stator between the two magnet rotors. Photos of the final pieces here <br />

[[File:prod05.jpg|300px]] <br />
<br />
Step - Generator, rotor: Preparation of the wheel hub.<br />
<br />
[[File:frame10.jpg|300px]]<br />
<br />
'''The wheel hub'''<br />
<br />
You can find a used car rear wheel hub (Golf, Toyota, etc.) that has a simple way to<br />
attach the axle, or alternatively buy a trailer hubs online new at low cost.<br />
PCD or ‘pitch circle diameter' is the diameter of the circle of the hole pattern in the<br />
hub, and usually this will be 100mm for a car wheel hub, or 4 inches for a trailer hub.<br />
Car hubs may have a brake-drum that you do not need. This can be removed using a<br />
cutting disk on a grinder. The simplest approach is to make four straight cuts around<br />
the four holes in the front, leaving a square surface to which you mount the magnet<br />
rotors. These photos show a golf rear wheel hub – first the brake-drum being cut, and<br />
then the finished hub after cutting off the drum.A typical rear wheel car hub with a <br />
flange on the back end of the stub shaft that can reused to mount it.<br />
Trailer hubs on the other hand are rather basic quality, and the bearings may be too<br />
cheap for long term use, but they are readily available items that can be purchased<br />
online as new. The drawings below (from autow.com) show a typical hub and stub<br />
axle which are bought separately.<br />
You need to be ready to replace the bearings with a named brand (such as SKF). It’s<br />
easy to replace the inner cones and rollers but the outer shells need to be knocked<br />
gently out of the hub with a suitable drift. Keep them straight by tapping evenly on<br />
opposite sides, and take care not to scratch the seating.<br />

Step - Generator, rotor: PreStep<br />
<br />
=== Section 4, involves the craving of the blades and the welding of the base for the turbine generator. ===<br />
<br />
4.1 Making the blades <br />
The drawknife is useful for thicker chunks of wood, and for cutting down into a hollow. <br />
It can make a nice smooth job of the root of the blade, whereas the plane will work better <br />
where you need a very straight finish.<br />
<br />
'''Marking the stations.'''<br />
<br />
Place the blade with its best edge toward you on its upper surface. This will actually<br />
become the back or ‘downwind’ side of the finished blade.<br />
(Most of the front or windward side is to be cut off, so defects on this underneath side<br />
are not important.)<br />
<br />
The root of the blade will be on your right, the tip at the left, 1000 mm from the root<br />
(near the left end).<br />
<br />
Measure from the root, and mark four stations.<br />
Station A at 75mm<br />
Station B at 150 mm<br />
Station C at 500 mm<br />
The Tip at 1000 mm.<br />
<br />
<br />
At each station draw a line right around the workpiece using a square.<br />
<br />
[[File:01tur.jpeg|400px]]<br />
<br />
<br />
'''Tapering the blade'''<br />
The width of the blade tapers down from full size at station C to 55 mm wide at the<br />
tip. Mark the 55 mm tip width, measuring from the leading edge side. Draw a line<br />
though your mark to the trailing edge side at C station and cut off a triangular piece so<br />
as to achieve the correct tapered shape for the blade. Any knots in the triangular<br />
off cut do not matter as this piece is discarded. Try to make this a "square" cut,<br />
perpendicular to the back surface of the blade.<br />
You can do this with a circular saw, or by cross-cutting and shaving as described<br />
above.<br />
<br />
<br />
[[File:02tur.jpeg|400px]]<br />
<br />
'''Marking the leading and trailing edges'''<br />
The next step is to cut the windward face of the blade. This face is defined by the<br />
leading and trailing edge lines of the blade. These lines need to be marked with<br />
reference to the back face of the wood which has been uppermost in the previous<br />
operation.<br />
<br />
Turn the wood over. Start by drawing two diagonal lines between stations A and B<br />
on the front or windward side (see below). One is on the front face and the other on<br />
the trailing edge which is now toward you. <br />
<br />
[[File:03tur.jpeg|400px]]<br />
<br />
<br />
Now draw the leading edge line as shown below, <br />
from station B, down to 16mm(from the back) at station C, then continuing to the tip at<br />
7mm from the back.<br />
<br />
[[File:04tur.jpeg|400px]]<br />
<br />
<br />
(This drawing does not show the extra bit beyond the tip which may remain <br />
in your actual workpiece.)<br />
<br />
Measurements are summarised in this table below. Heights are from the back of the<br />
blade which will then rest on the bench. Remove the wood above this height. "Full"<br />
refers to the full thickness of the original piece of wood you are using.<br />
<br />
<br />
<br />
[[File:05tur.jpeg|400px]]<br />
<br />
<br />
'''The trailing''' <br />
The trailing edge line starts at the bottom of the diagonal line at station B, and <br />
rises to 5mm at C, continuing at 5 mm to the tip. This view below shows the wood <br />
already removed between the two lines to form the windward face of the blade.<br />
<br />
<br />
[[File:06tur.png|400px]]<br />
<br />
<br />
Carve this flat windward face between the 2 lines. Take care that the edges are<br />
straight, following the lines. The best tool to use for finishing the outer part of the<br />
blade is a plane, to give a smooth, straight finish. You may need to work the plane at<br />
45 degrees to the workpiece, sliding partly sideways, to form the hollow shape at<br />
station C.<br />
<br />
This step is completed when you can place a ruler across the face between the leading<br />
and trailing edge lines and there is no ‘hump’ in the middle. Fill any chips or small<br />
hollows with wood filler. If there are any serious errors, or large knots that weaken<br />
the blade then it may have to be discarded.<br />
Check the “drop” using a level as a reference. Clamp the wood so that the root part<br />
sits level, and measure the difference in level between the leading and trailing edges.<br />
The difference or “drop” should be 11 mm at the 500 mm mid-point, and 2 mm at the<br />
tip.<br />

"Pedagoxías do vento e das estrelas. As relacións sociais ás que (nunca estabamos destinados a) sobrevivir, tamén vivimos nos nosos corpos dolorosamente, e Audre Lorde non está aquí para lembrarnos esta lección, salvo na medida en que está presente no vento pedagóxico.<br />
Pero o vento é o noso mestre (74). -Alexis Pauline Gumbs "<br />
<br />
O principal obxectivo deste evento é prototipar un xerador eólico a pequena escala para camiñar xuntos cara á autosuficiencia neste campo.<br />
Temos o pracer de comunicarvos que do 16 ao 23 de outubro Biotranslab de Pin e The Foundry establecen unha colaboración para levar a cabo o evento Eco (i) Logic Queer Energy harvesting. O proxecto é posible grazas ao apoio de GOSH, unha rede para desenvolver e difundir proxectos baseados en hardware de código aberto para a ciencia.<br />
<br />
EcoLoxicas Queer para a captación de enerxía eolica. <br />
O evento ten como obxectivo abordar a falta de mulleres, queer, trans e diversidade nos ámbitos tecnolóxicos en xeral e do hacking máis concretamente. Pero aínda máis, pretende crear unha comunidade que avalía criticamente as narrativas hexemónicas arredor das tecnoloxías, os aspectos de modernidade dos seus supostos occidentais subliñados e as súas inflexións capitalistas inherentes, entre outros.<br />
O obxectivo principal do evento é desenvolver kits que se centren na interacción co medio natural no ámbito da enerxía.. o obxectivo principal pasa pola captación de enerxía do medio natural, a través dos aeroxeradores. Estes kits de enerxía serán escalables e poderán utilizarse tanto como material pedagóxico como para instalar centrais eléctricas específicas do sitio en diferentes sitios tamén. Este traballo ten un compoñente contrainfraestrutural: unha posible consecuencia sería capacitar ás persoas para xerar a súa propia enerxía en lugar de depender de grandes empresas e moitas veces extractivas.<br />

''Pedagogies of the Wind and Stars. The social relations that we (were never meant to) survive, also live in our bodies painfully, and Audre Lorde is not here to remind us of this lesson herself, except in as much that she is present in the pedagogical wind. But wind is our teacher (74). -Alexis Pauline Gumbs'' from the book Mapping Queer Space(s) of Praxis and Pedagogy <br />
Editors: Elizabeth McNeil, James E. Wermers, Joshua O. Lunn'' <br />
<br />
We have the pleasure to communicate you that from 16 to 29 of October Pin Biotranslab, Casa do Río e The Foundry establishes a collaboration to run the event Eco (i) Logic Queer Energy harvesting. The project is possible thanks to the support of GOSH, an network for develop and disseminate projects based on Open Source hardware for Science.<br />
<br />
'''Eco (i) Logic Queer Energy harvesting''' <br />
The event aims at addressing the lack of women, queer, trans and diversity in technological fields in general and hacking more specifically. But even more so, it aims at creating a community that critically assesses the hegemonic narratives around technologies, the modernity aspects of its underlining Western assumptions and its inherent capitalist inflections, among others.<br />
The main purpose of the event is to develop kits that focus on interacting with the natural environment on the field of energy.. the main objective lies on harvesting energy of the natural environment, through wind turbines. These power kits will be scalable and can be used both as pedagogical material and to set up site-specific power plants in different sites as well. There is a counter-infrastructural component to this work: one possible consequence would be to empower people to generate their own energy instead of relying on large and often extractive companies.<br />
<br />
== Introduction and values of the process ==<br />
<br />
Here starts the documentation of the long process of the prototyping the Hugh Piggott The Piggott Turbine – Wind Empowerment model of an Open source wind turbine. We were changing a bit the goals of the event from developing small kits to going to build the real 2m size wind turbine to provide energy to the rural regional areas we were working on. In that specific event we were working at The Foundry a nice project and association that we have settled on the north part of GaliZA into the Northwest of Spain.<br />
<br />
During the event many things have been activated between the doers and the visitors; In general It was a wondering experience full of new things to study, learn, doing and understand together. <br />
<br />
We chose this model because It was full of layers of interest on the levels of learning, understanding and making it, here some levels mixed up with layers: <br />
<br />
first to all is one of the ones that is '''open source''' or at least has the option to access the full documentation.<br />
<br />
really '''rich on the pedagogical level''', we were really learning through the complete building of the generator itself, about many topics as :<br />
* electromagnetism<br />
* mathematics<br />
* geometry<br />
* electronics<br />
* AC-DC<br />
* welding<br />
* wood carving<br />
* sculpting and casting pieces<br />
and much more that was reaching through the nice process of reading, learning and building together.<br />
<br />
== Glossary ==<br />
<br />
* '''AC-'''Alternating current as produced by the alternator. All thread - USA word for 'threaded' or 'spun' rod or studding<br />
* '''Brake switch''' - A switch used to short-circuit the wires from the alternator so that it stops.<br />
* '''Catalyst''' - A chemical used to make the polyester resin set solid. Catalyst reacts with 'accelerator' already present in the resin mix. <br />
The heat of reaction sets the polyester.<br />
* '''Cavalier''' - A make of car. The cavalier in the UK is not the same as the Cavalier in the USA but both have useful wheel hubs.<br />
* '''DC - direct current''' with a positive and a negative side, as in battery circuits.<br />
* '''Diameter''' - The distance from one side of a circle to another. The width of a disk right across the middle.<br />
* '''Phase''' - The timing of the cyclical alternation of voltage in a circuit. Different phases will peak at different times.<br />
* '''Polyester''' - A type of resin used in fibreglass work. Also suitable for making castings.<br />
* '''Power''' - the rate of delivery of energy<br />
* '''Rectifier''' - A semiconductor device that turns AC into DC for charging the battery.<br />
* '''Root''' - The widest part of the blade near to the hub at the center of the rotor.<br />
* '''Rotor''' - A rotating part. Magnet rotors are the steel diskscarrying the magnets past the stator. Rotor blades are the 'propeller' <br />
driven by the wind and driving the magnet rotors.<br />
* '''Soldering''' - A method for making electrical connections between wires using a hot 'iron' and coating everything with molten solder.<br />
* '''Drag''' - A force exerted by the wind on an object. Drag is parallel to the wind direction at the object. (see Lift) <br />
* '''Stator''' - An assembly of coils embedded in a slab of resin to form part of the alternator. The magnets induce a voltage in the coils and we can use this to charge a battery.<br />
* '''Drop''' - Used here to describe a certain measurement of the shape of a windmill blade. The 'drop' affects the angle of<br />
the blade to the wind. Styrene monomer - A nasty smelling solvent in the polyester resin mix.<br />
* '''Flux''' - The 'stuff' of magnetism. Similar to 'current' in electricity. It can be visualized as 'lines' coming out of one pole and <br />
returning to the other.<br />
* '''Furling''' - A protective action that reduces exposure to violent winds by facing the blades away from them.<br />
* '''Jig''' - A device used to hold the magnets in place before setting them in resin.<br />
* '''Leading edge''' - The edge of a blade that would strike an object placed in its path as the rotor spins.<br />
* '''Lift''' - A force exerted by the wind on an object. Lift is at right angles to the wind direction at the object. (see Drag)<br />
* '''Mold''' - A shaped container in which resin castings are formed. The mould can be discarded after the casting has set.<br />
* '''Multimeter''' - A versatile electrical test instrument, used to measure voltage, current and other parameters.<br />
* '''Neodymium''' - The name given to a type of permanent magnet containing neodymium, iron and boron. These magnets are very strong and <br />
getting cheaper all the time.<br />
* '''Offset''' - An eccentric position, off centre.<br />
* '''Talcum powder'''- A cheap filler powder used to thicken the resin and slow its reaction (prevent it overheating).<br />
* '''Tail''' - A projecting vane mounted on a boom at the back ofthe windmill used to steer it into or out of the wind automatically.<br />
* '''Tap''' - a tool for making thread inside holes so you can fit a screw into the hole.<br />
* '''Thrust''' - The force of the wind pushing the machine backwards.<br />
* '''Tower''' - The mast supporting the windmill.<br />
* '''Trailing edge''' - The blade edge furthest from the leading edge. The trailing edge is sharpened, so as to release the passing <br />
air without turbulence.<br />
* '''Wedges''' - Tapered pieces of wood used to build up the blade thickness and increase its angle to the wind near the root.<br />
* '''Work-piece''' - The piece of wood or metal being shaped in the workshop.<br />
* '''Yaw bearing''' - the swivel at the top of the tower on which the windmill is mounted. The yaw bearing allows the windmill to face the wind.<br />

== The space == <br />
<br />
=== The Foundry ===<br />
The Foundry is a non-profit organization based in a previously abandoned GaliZA village. It functions both as a residency and as a project space. It subscribes to the ideals of self-organization, and has the following three objectives:<br />
1. Organizing activities in the field of the arts, science and humanities outside of traditional institutions, focusing on critical discourse.<br />
2. Promoting the exchange of ideas and intellectual collaboration outside of the constraints imposed by state and market.<br />
3. Increasing self-sufficiency, sustainability, and an awareness of the environment using appropriate technology and open source as main resources.<br />
Taking into account this context, our aim is to reinforce the capacity to generate networks flowing from rural to urban context supporting non hierarchy and democratic exchanges of knowledge and practices that can enable new and sustainable models within rural contexts. According to that we consider that the new trans-disciplinary creative sectors in which we are entangled can have a huge and positive impact in the creation of this new paradigm. https://bravosfoundry.com/<br />
Aside from that, there is thematic focus on transdisciplinarity, transfeminism and post-humanism. While this focus is not adequately grasped by identity-political categories like race or gender, we hope it leads to the subversion of hegemonic structures inscribed in the binarisms upholding many of these categories. Our interest lies in the development of tools and technologies that subvert contemporary structures of domination, exploitation and marginalization, not in those that reproduce it.<br />
We seek to develop a more sustainable environment by opening up our practices based on a free culture framework, generating networks and interest around them, enabling a flow of exchange of innovation across creative sectors focusing on revaluation of rural contexts and its knowledge heritage.<br />

=== '''Section 2, involves the construction of '''the alternator''' parts using the devices from the section 1.''' ===<br />
<br />
'''Alternator'''<br />
Each magnet rotor is a steel disk with 12 magnets placed on it and set in resin. The magnets are each 50 x 50 x 20 mm, and they only just fit on the disk. The idea is to achieve the maximum amount of flux in a given space.<br />
The turbine runs at 650 rpm for 400W output, so the centrifugal force on the magnets is 60 times the force of gravity. To prevent them flying off, the resin casting needs to be reinforced. Stainless steel wire rope is placed around the outside of the magnets to hold the casting together at high rpm. We use stainless because it is non-magnetic, or at least less magnetic than normal steel wire rope. <br />
<br />
You will wind the coils that produce the output power and cast them in resin to form a stator between the two magnet rotors. Photos of the final pieces here <br />

[[File:prod05.jpg|300px]] <br />
<br />
Step - Generator, rotor: Preparation of the wheel hub.<br />
<br />
[[File:frame10.jpg|300px]]<br />
<br />
'''The wheel hub'''<br />
<br />
You can find a used car rear wheel hub (Golf, Toyota, etc.) that has a simple way to<br />
attach the axle, or alternatively buy a trailer hubs online new at low cost.<br />
PCD or ‘pitch circle diameter' is the diameter of the circle of the hole pattern in the<br />
hub, and usually this will be 100mm for a car wheel hub, or 4 inches for a trailer hub.<br />
Car hubs may have a brake-drum that you do not need. This can be removed using a<br />
cutting disk on a grinder. The simplest approach is to make four straight cuts around<br />
the four holes in the front, leaving a square surface to which you mount the magnet<br />
rotors. These photos show a golf rear wheel hub – first the brake-drum being cut, and<br />
then the finished hub after cutting off the drum.A typical rear wheel car hub with a <br />
flange on the back end of the stub shaft that can reused to mount it.<br />
Trailer hubs on the other hand are rather basic quality, and the bearings may be too<br />
cheap for long term use, but they are readily available items that can be purchased<br />
online as new. The drawings below (from autow.com) show a typical hub and stub<br />
axle which are bought separately.<br />
You need to be ready to replace the bearings with a named brand (such as SKF). It’s<br />
easy to replace the inner cones and rollers but the outer shells need to be knocked<br />
gently out of the hub with a suitable drift. Keep them straight by tapping evenly on<br />
opposite sides, and take care not to scratch the seating.<br />

Step - Generator, rotor: PreStep<br />
<br />
=== Section 4, involves the craving of the blades and the welding of the base for the turbine generator. ===<br />
<br />
4.1 Making the blades <br />
The drawknife is useful for thicker chunks of wood, and for cutting down into a hollow. <br />
It can make a nice smooth job of the root of the blade, whereas the plane will work better <br />
where you need a very straight finish.<br />
<br />
'''Marking the stations.'''<br />
<br />
Place the blade with its best edge toward you on its upper surface. This will actually<br />
become the back or ‘downwind’ side of the finished blade.<br />
(Most of the front or windward side is to be cut off, so defects on this underneath side<br />
are not important.)<br />
<br />
The root of the blade will be on your right, the tip at the left, 1000 mm from the root<br />
(near the left end).<br />
<br />
Measure from the root, and mark four stations.<br />
Station A at 75mm<br />
Station B at 150 mm<br />
Station C at 500 mm<br />
The Tip at 1000 mm.<br />
<br />
<br />
At each station draw a line right around the workpiece using a square.<br />
<br />
[[File:01tur.jpeg|400px]]<br />
<br />
<br />
'''Tapering the blade'''<br />
The width of the blade tapers down from full size at station C to 55 mm wide at the<br />
tip. Mark the 55 mm tip width, measuring from the leading edge side. Draw a line<br />
though your mark to the trailing edge side at C station and cut off a triangular piece so<br />
as to achieve the correct tapered shape for the blade. Any knots in the triangular<br />
off cut do not matter as this piece is discarded. Try to make this a "square" cut,<br />
perpendicular to the back surface of the blade.<br />
You can do this with a circular saw, or by cross-cutting and shaving as described<br />
above.<br />
<br />
<br />
[[File:02tur.jpeg|400px]]<br />
<br />
'''Marking the leading and trailing edges'''<br />
The next step is to cut the windward face of the blade. This face is defined by the<br />
leading and trailing edge lines of the blade. These lines need to be marked with<br />
reference to the back face of the wood which has been uppermost in the previous<br />
operation.<br />
<br />
Turn the wood over. Start by drawing two diagonal lines between stations A and B<br />
on the front or windward side (see below). One is on the front face and the other on<br />
the trailing edge which is now toward you. <br />
<br />
[[File:03tur.jpeg|400px]]<br />
<br />
<br />
Now draw the leading edge line as shown below, <br />
from station B, down to 16mm(from the back) at station C, then continuing to the tip at<br />
7mm from the back.<br />
<br />
[[File:04tur.jpeg|400px]]<br />
<br />
<br />
(This drawing does not show the extra bit beyond the tip which may remain <br />
in your actual workpiece.)<br />
<br />
Measurements are summarised in this table below. Heights are from the back of the<br />
blade which will then rest on the bench. Remove the wood above this height. "Full"<br />
refers to the full thickness of the original piece of wood you are using.<br />
<br />
<br />
<br />
[[File:05tur.jpeg|400px]]<br />
<br />
<br />
'''The trailing''' <br />
The trailing edge line starts at the bottom of the diagonal line at station B, and <br />
rises to 5mm at C, continuing at 5 mm to the tip. This view below shows the wood <br />
already removed between the two lines to form the windward face of the blade.<br />
<br />
<br />
[[File:06tur.png|400px]]<br />
<br />
<br />
Carve this flat windward face between the 2 lines. Take care that the edges are<br />
straight, following the lines. The best tool to use for finishing the outer part of the<br />
blade is a plane, to give a smooth, straight finish. You may need to work the plane at<br />
45 degrees to the workpiece, sliding partly sideways, to form the hollow shape at<br />
station C.<br />
<br />
This step is completed when you can place a ruler across the face between the leading<br />
and trailing edge lines and there is no ‘hump’ in the middle. Fill any chips or small<br />
hollows with wood filler. If there are any serious errors, or large knots that weaken<br />
the blade then it may have to be discarded.<br />
Check the “drop” using a level as a reference. Clamp the wood so that the root part<br />
sits level, and measure the difference in level between the leading and trailing edges.<br />
The difference or “drop” should be 11 mm at the 500 mm mid-point, and 2 mm at the<br />
tip.<br />

"Pedagoxías do vento e das estrelas. As relacións sociais ás que (nunca estabamos destinados a) sobrevivir, tamén vivimos nos nosos corpos dolorosamente, e Audre Lorde non está aquí para lembrarnos esta lección, salvo na medida en que está presente no vento pedagóxico.<br />
Pero o vento é o noso mestre (74). -Alexis Pauline Gumbs "<br />
<br />
O principal obxectivo deste evento é prototipar un xerador eólico a pequena escala para camiñar xuntos cara á autosuficiencia neste campo.<br />
Temos o pracer de comunicarvos que do 16 ao 23 de outubro Biotranslab de Pin e The Foundry establecen unha colaboración para levar a cabo o evento Eco (i) Logic Queer Energy harvesting. O proxecto é posible grazas ao apoio de GOSH, unha rede para desenvolver e difundir proxectos baseados en hardware de código aberto para a ciencia.<br />
<br />
EcoLoxicas Queer para a captación de enerxía eolica. <br />
O evento ten como obxectivo abordar a falta de mulleres, queer, trans e diversidade nos ámbitos tecnolóxicos en xeral e do hacking máis concretamente. Pero aínda máis, pretende crear unha comunidade que avalía criticamente as narrativas hexemónicas arredor das tecnoloxías, os aspectos de modernidade dos seus supostos occidentais subliñados e as súas inflexións capitalistas inherentes, entre outros.<br />
O obxectivo principal do evento é desenvolver kits que se centren na interacción co medio natural no ámbito da enerxía.. o obxectivo principal pasa pola captación de enerxía do medio natural, a través dos aeroxeradores. Estes kits de enerxía serán escalables e poderán utilizarse tanto como material pedagóxico como para instalar centrais eléctricas específicas do sitio en diferentes sitios tamén. Este traballo ten un compoñente contrainfraestrutural: unha posible consecuencia sería capacitar ás persoas para xerar a súa propia enerxía en lugar de depender de grandes empresas e moitas veces extractivas.<br />

''Pedagogies of the Wind and Stars. The social relations that we (were never meant to) survive, also live in our bodies painfully, and Audre Lorde is not here to remind us of this lesson herself, except in as much that she is present in the pedagogical wind. But wind is our teacher (74). -Alexis Pauline Gumbs'' from the book Mapping Queer Space(s) of Praxis and Pedagogy <br />
Editors: Elizabeth McNeil, James E. Wermers, Joshua O. Lunn'' <br />
<br />
We have the pleasure to communicate you that from 16 to 29 of October Pin Biotranslab, Casa do Río e The Foundry establishes a collaboration to run the event Eco (i) Logic Queer Energy harvesting. The project is possible thanks to the support of GOSH, an network for develop and disseminate projects based on Open Source hardware for Science.<br />
<br />
'''Eco (i) Logic Queer Energy harvesting''' <br />
The event aims at addressing the lack of women, queer, trans and diversity in technological fields in general and hacking more specifically. But even more so, it aims at creating a community that critically assesses the hegemonic narratives around technologies, the modernity aspects of its underlining Western assumptions and its inherent capitalist inflections, among others.<br />
The main purpose of the event is to develop kits that focus on interacting with the natural environment on the field of energy.. the main objective lies on harvesting energy of the natural environment, through wind turbines. These power kits will be scalable and can be used both as pedagogical material and to set up site-specific power plants in different sites as well. There is a counter-infrastructural component to this work: one possible consequence would be to empower people to generate their own energy instead of relying on large and often extractive companies.<br />
<br />
== Introduction and values of the process ==<br />
<br />
Here starts the documentation of the long process of the prototyping the Hugh Piggott The Piggott Turbine – Wind Empowerment model of an Open source wind turbine. We were changing a bit the goals of the event from developing small kits to going to build the real 2m size wind turbine to provide energy to the rural regional areas we were working on. In that specific event we were working at The Foundry a nice project and association that we have settled on the north part of GaliZA into the Northwest of Spain.<br />
<br />
During the event many things have been activated between the doers and the visitors; In general It was a wondering experience full of new things to study, learn, doing and understand together. <br />
<br />
We chose this model because It was full of layers of interest on the levels of learning, understanding and making it, here some levels mixed up with layers: <br />
<br />
first to all is one of the ones that is '''open source''' or at least has the option to access the full documentation.<br />
<br />
really '''rich on the pedagogical level''', we were really learning through the complete building of the generator itself, about many topics as :<br />
* electromagnetism<br />
* mathematics<br />
* geometry<br />
* electronics<br />
* AC-DC<br />
* welding<br />
* wood carving<br />
* sculpting and casting pieces<br />
and much more that was reaching through the nice process of reading, learning and building together.<br />
<br />
== Glossary ==<br />
<br />
* '''AC-'''Alternating current as produced by the alternator. All thread - USA word for 'threaded' or 'spun' rod or studding<br />
* '''Brake switch''' - A switch used to short-circuit the wires from the alternator so that it stops.<br />
* '''Catalyst''' - A chemical used to make the polyester resin set solid. Catalyst reacts with 'accelerator' already present in the resin mix. <br />
The heat of reaction sets the polyester.<br />
* '''Cavalier''' - A make of car. The cavalier in the UK is not the same as the Cavalier in the USA but both have useful wheel hubs.<br />
* '''DC - direct current''' with a positive and a negative side, as in battery circuits.<br />
* '''Diameter''' - The distance from one side of a circle to another. The width of a disk right across the middle.<br />
* '''Phase''' - The timing of the cyclical alternation of voltage in a circuit. Different phases will peak at different times.<br />
* '''Polyester''' - A type of resin used in fibreglass work. Also suitable for making castings.<br />
* '''Power''' - the rate of delivery of energy<br />
* '''Rectifier''' - A semiconductor device that turns AC into DC for charging the battery.<br />
* '''Root''' - The widest part of the blade near to the hub at the center of the rotor.<br />
* '''Rotor''' - A rotating part. Magnet rotors are the steel diskscarrying the magnets past the stator. Rotor blades are the 'propeller' <br />
driven by the wind and driving the magnet rotors.<br />
* '''Soldering''' - A method for making electrical connections between wires using a hot 'iron' and coating everything with molten solder.<br />
* '''Drag''' - A force exerted by the wind on an object. Drag is parallel to the wind direction at the object. (see Lift) <br />
* '''Stator''' - An assembly of coils embedded in a slab of resin to form part of the alternator. The magnets induce a voltage in the coils and we can use this to charge a battery.<br />
* '''Drop''' - Used here to describe a certain measurement of the shape of a windmill blade. The 'drop' affects the angle of<br />
the blade to the wind. Styrene monomer - A nasty smelling solvent in the polyester resin mix.<br />
* '''Flux''' - The 'stuff' of magnetism. Similar to 'current' in electricity. It can be visualized as 'lines' coming out of one pole and <br />
returning to the other.<br />
* '''Furling''' - A protective action that reduces exposure to violent winds by facing the blades away from them.<br />
* '''Jig''' - A device used to hold the magnets in place before setting them in resin.<br />
* '''Leading edge''' - The edge of a blade that would strike an object placed in its path as the rotor spins.<br />
* '''Lift''' - A force exerted by the wind on an object. Lift is at right angles to the wind direction at the object. (see Drag)<br />
* '''Mold''' - A shaped container in which resin castings are formed. The mould can be discarded after the casting has set.<br />
* '''Multimeter''' - A versatile electrical test instrument, used to measure voltage, current and other parameters.<br />
* '''Neodymium''' - The name given to a type of permanent magnet containing neodymium, iron and boron. These magnets are very strong and <br />
getting cheaper all the time.<br />
* '''Offset''' - An eccentric position, off centre.<br />
* '''Talcum powder'''- A cheap filler powder used to thicken the resin and slow its reaction (prevent it overheating).<br />
* '''Tail''' - A projecting vane mounted on a boom at the back ofthe windmill used to steer it into or out of the wind automatically.<br />
* '''Tap''' - a tool for making thread inside holes so you can fit a screw into the hole.<br />
* '''Thrust''' - The force of the wind pushing the machine backwards.<br />
* '''Tower''' - The mast supporting the windmill.<br />
* '''Trailing edge''' - The blade edge furthest from the leading edge. The trailing edge is sharpened, so as to release the passing <br />
air without turbulence.<br />
* '''Wedges''' - Tapered pieces of wood used to build up the blade thickness and increase its angle to the wind near the root.<br />
* '''Work-piece''' - The piece of wood or metal being shaped in the workshop.<br />
* '''Yaw bearing''' - the swivel at the top of the tower on which the windmill is mounted. The yaw bearing allows the windmill to face the wind.<br />

== The space == <br />
<br />
=== The Foundry ===<br />
The Foundry is a non-profit organization based in a previously abandoned GaliZA village. It functions both as a residency and as a project space. It subscribes to the ideals of self-organization, and has the following three objectives:<br />
1. Organizing activities in the field of the arts, science and humanities outside of traditional institutions, focusing on critical discourse.<br />
2. Promoting the exchange of ideas and intellectual collaboration outside of the constraints imposed by state and market.<br />
3. Increasing self-sufficiency, sustainability, and an awareness of the environment using appropriate technology and open source as main resources.<br />
Taking into account this context, our aim is to reinforce the capacity to generate networks flowing from rural to urban context supporting non hierarchy and democratic exchanges of knowledge and practices that can enable new and sustainable models within rural contexts. According to that we consider that the new trans-disciplinary creative sectors in which we are entangled can have a huge and positive impact in the creation of this new paradigm. https://bravosfoundry.com/<br />
Aside from that, there is thematic focus on transdisciplinarity, transfeminism and post-humanism. While this focus is not adequately grasped by identity-political categories like race or gender, we hope it leads to the subversion of hegemonic structures inscribed in the binarisms upholding many of these categories. Our interest lies in the development of tools and technologies that subvert contemporary structures of domination, exploitation and marginalization, not in those that reproduce it.<br />
We seek to develop a more sustainable environment by opening up our practices based on a free culture framework, generating networks and interest around them, enabling a flow of exchange of innovation across creative sectors focusing on revaluation of rural contexts and its knowledge heritage.<br />

=== '''Section 2, involves the construction of '''the alternator''' parts using the devices from the section 1.''' ===<br />
<br />
'''Alternator'''<br />
Each magnet rotor is a steel disk with 12 magnets placed on it and set in resin. The magnets are each 50 x 50 x 20 mm, and they only just fit on the disk. The idea is to achieve the maximum amount of flux in a given space.<br />
The turbine runs at 650 rpm for 400W output, so the centrifugal force on the magnets is 60 times the force of gravity. To prevent them flying off, the resin casting needs to be reinforced. Stainless steel wire rope is placed around the outside of the magnets to hold the casting together at high rpm. We use stainless because it is non-magnetic, or at least less magnetic than normal steel wire rope. <br />
<br />
You will wind the coils that produce the output power and cast them in resin to form a stator between the two magnet rotors. Photos of the final pieces here <br />

[[File:prod05.jpg|300px]] <br />
<br />
Step - Generator, rotor: Preparation of the wheel hub.<br />
<br />
[[File:frame10.jpg|300px]]<br />
<br />
'''The wheel hub'''<br />
<br />
You can find a used car rear wheel hub (Golf, Toyota, etc.) that has a simple way to<br />
attach the axle, or alternatively buy a trailer hubs online new at low cost.<br />
PCD or ‘pitch circle diameter' is the diameter of the circle of the hole pattern in the<br />
hub, and usually this will be 100mm for a car wheel hub, or 4 inches for a trailer hub.<br />
Car hubs may have a brake-drum that you do not need. This can be removed using a<br />
cutting disk on a grinder. The simplest approach is to make four straight cuts around<br />
the four holes in the front, leaving a square surface to which you mount the magnet<br />
rotors. These photos show a golf rear wheel hub – first the brake-drum being cut, and<br />
then the finished hub after cutting off the drum.A typical rear wheel car hub with a <br />
flange on the back end of the stub shaft that can reused to mount it.<br />
Trailer hubs on the other hand are rather basic quality, and the bearings may be too<br />
cheap for long term use, but they are readily available items that can be purchased<br />
online as new. The drawings below (from autow.com) show a typical hub and stub<br />
axle which are bought separately.<br />
You need to be ready to replace the bearings with a named brand (such as SKF). It’s<br />
easy to replace the inner cones and rollers but the outer shells need to be knocked<br />
gently out of the hub with a suitable drift. Keep them straight by tapping evenly on<br />
opposite sides, and take care not to scratch the seating.<br />

Step - Generator, rotor: PreStep<br />
<br />
=== Section 4, involves the craving of the blades and the welding of the base for the turbine generator. ===<br />
<br />
4.1 Making the blades <br />
The drawknife is useful for thicker chunks of wood, and for cutting down into a hollow. <br />
It can make a nice smooth job of the root of the blade, whereas the plane will work better <br />
where you need a very straight finish.<br />
<br />
'''Marking the stations.'''<br />
<br />
Place the blade with its best edge toward you on its upper surface. This will actually<br />
become the back or ‘downwind’ side of the finished blade.<br />
(Most of the front or windward side is to be cut off, so defects on this underneath side<br />
are not important.)<br />
<br />
The root of the blade will be on your right, the tip at the left, 1000 mm from the root<br />
(near the left end).<br />
<br />
Measure from the root, and mark four stations.<br />
Station A at 75mm<br />
Station B at 150 mm<br />
Station C at 500 mm<br />
The Tip at 1000 mm.<br />
<br />
<br />
At each station draw a line right around the workpiece using a square.<br />
<br />
[[File:01tur.jpeg|400px]]<br />
<br />
<br />
'''Tapering the blade'''<br />
The width of the blade tapers down from full size at station C to 55 mm wide at the<br />
tip. Mark the 55 mm tip width, measuring from the leading edge side. Draw a line<br />
though your mark to the trailing edge side at C station and cut off a triangular piece so<br />
as to achieve the correct tapered shape for the blade. Any knots in the triangular<br />
off cut do not matter as this piece is discarded. Try to make this a "square" cut,<br />
perpendicular to the back surface of the blade.<br />
You can do this with a circular saw, or by cross-cutting and shaving as described<br />
above.<br />
<br />
<br />
[[File:02tur.jpeg|400px]]<br />
<br />
'''Marking the leading and trailing edges'''<br />
The next step is to cut the windward face of the blade. This face is defined by the<br />
leading and trailing edge lines of the blade. These lines need to be marked with<br />
reference to the back face of the wood which has been uppermost in the previous<br />
operation.<br />
<br />
Turn the wood over. Start by drawing two diagonal lines between stations A and B<br />
on the front or windward side (see below). One is on the front face and the other on<br />
the trailing edge which is now toward you. <br />
<br />
[[File:03tur.jpeg|400px]]<br />
<br />
<br />
Now draw the leading edge line as shown below, <br />
from station B, down to 16mm(from the back) at station C, then continuing to the tip at<br />
7mm from the back.<br />
<br />
[[File:04tur.jpeg|400px]]<br />
<br />
<br />
(This drawing does not show the extra bit beyond the tip which may remain <br />
in your actual workpiece.)<br />
<br />
Measurements are summarised in this table below. Heights are from the back of the<br />
blade which will then rest on the bench. Remove the wood above this height. "Full"<br />
refers to the full thickness of the original piece of wood you are using.<br />
<br />
<br />
<br />
[[File:05tur.jpeg|400px]]<br />
<br />
<br />
'''The trailing''' <br />
The trailing edge line starts at the bottom of the diagonal line at station B, and <br />
rises to 5mm at C, continuing at 5 mm to the tip. This view below shows the wood <br />
already removed between the two lines to form the windward face of the blade.<br />
<br />
<br />
[[File:06tur.png|400px]]<br />
<br />
<br />
Carve this flat windward face between the 2 lines. Take care that the edges are<br />
straight, following the lines. The best tool to use for finishing the outer part of the<br />
blade is a plane, to give a smooth, straight finish. You may need to work the plane at<br />
45 degrees to the workpiece, sliding partly sideways, to form the hollow shape at<br />
station C.<br />
<br />
This step is completed when you can place a ruler across the face between the leading<br />
and trailing edge lines and there is no ‘hump’ in the middle. Fill any chips or small<br />
hollows with wood filler. If there are any serious errors, or large knots that weaken<br />
the blade then it may have to be discarded.<br />
Check the “drop” using a level as a reference. Clamp the wood so that the root part<br />
sits level, and measure the difference in level between the leading and trailing edges.<br />
The difference or “drop” should be 11 mm at the 500 mm mid-point, and 2 mm at the<br />
tip.<br />

"Pedagoxías do vento e das estrelas. As relacións sociais ás que (nunca estabamos destinados a) sobrevivir, tamén vivimos nos nosos corpos dolorosamente, e Audre Lorde non está aquí para lembrarnos esta lección, salvo na medida en que está presente no vento pedagóxico.<br />
Pero o vento é o noso mestre (74). -Alexis Pauline Gumbs "<br />
<br />
O principal obxectivo deste evento é prototipar un xerador eólico a pequena escala para camiñar xuntos cara á autosuficiencia neste campo.<br />
Temos o pracer de comunicarvos que do 16 ao 23 de outubro Biotranslab de Pin e The Foundry establecen unha colaboración para levar a cabo o evento Eco (i) Logic Queer Energy harvesting. O proxecto é posible grazas ao apoio de GOSH, unha rede para desenvolver e difundir proxectos baseados en hardware de código aberto para a ciencia.<br />
<br />
EcoLoxicas Queer para a captación de enerxía eolica. <br />
O evento ten como obxectivo abordar a falta de mulleres, queer, trans e diversidade nos ámbitos tecnolóxicos en xeral e do hacking máis concretamente. Pero aínda máis, pretende crear unha comunidade que avalía criticamente as narrativas hexemónicas arredor das tecnoloxías, os aspectos de modernidade dos seus supostos occidentais subliñados e as súas inflexións capitalistas inherentes, entre outros.<br />
O obxectivo principal do evento é desenvolver kits que se centren na interacción co medio natural no ámbito da enerxía.. o obxectivo principal pasa pola captación de enerxía do medio natural, a través dos aeroxeradores. Estes kits de enerxía serán escalables e poderán utilizarse tanto como material pedagóxico como para instalar centrais eléctricas específicas do sitio en diferentes sitios tamén. Este traballo ten un compoñente contrainfraestrutural: unha posible consecuencia sería capacitar ás persoas para xerar a súa propia enerxía en lugar de depender de grandes empresas e moitas veces extractivas.<br />

''Pedagogies of the Wind and Stars. The social relations that we (were never meant to) survive, also live in our bodies painfully, and Audre Lorde is not here to remind us of this lesson herself, except in as much that she is present in the pedagogical wind. But wind is our teacher (74). -Alexis Pauline Gumbs'' from the book Mapping Queer Space(s) of Praxis and Pedagogy <br />
Editors: Elizabeth McNeil, James E. Wermers, Joshua O. Lunn'' <br />
<br />
We have the pleasure to communicate you that from 16 to 29 of October Pin Biotranslab, Casa do Río e The Foundry establishes a collaboration to run the event Eco (i) Logic Queer Energy harvesting. The project is possible thanks to the support of GOSH, an network for develop and disseminate projects based on Open Source hardware for Science.<br />
<br />
'''Eco (i) Logic Queer Energy harvesting''' <br />
The event aims at addressing the lack of women, queer, trans and diversity in technological fields in general and hacking more specifically. But even more so, it aims at creating a community that critically assesses the hegemonic narratives around technologies, the modernity aspects of its underlining Western assumptions and its inherent capitalist inflections, among others.<br />
The main purpose of the event is to develop kits that focus on interacting with the natural environment on the field of energy.. the main objective lies on harvesting energy of the natural environment, through wind turbines. These power kits will be scalable and can be used both as pedagogical material and to set up site-specific power plants in different sites as well. There is a counter-infrastructural component to this work: one possible consequence would be to empower people to generate their own energy instead of relying on large and often extractive companies.<br />
<br />
== Introduction and values of the process ==<br />
<br />
Here starts the documentation of the long process of the prototyping the Hugh Piggott The Piggott Turbine – Wind Empowerment model of an Open source wind turbine. We were changing a bit the goals of the event from developing small kits to going to build the real 2m size wind turbine to provide energy to the rural regional areas we were working on. In that specific event we were working at The Foundry a nice project and association that we have settled on the north part of GaliZA into the Northwest of Spain.<br />
<br />
During the event many things have been activated between the doers and the visitors; In general It was a wondering experience full of new things to study, learn, doing and understand together. <br />
<br />
We chose this model because It was full of layers of interest on the levels of learning, understanding and making it, here some levels mixed up with layers: <br />
<br />
first to all is one of the ones that is '''open source''' or at least has the option to access the full documentation.<br />
<br />
really '''rich on the pedagogical level''', we were really learning through the complete building of the generator itself, about many topics as :<br />
* electromagnetism<br />
* mathematics<br />
* geometry<br />
* electronics<br />
* AC-DC<br />
* welding<br />
* wood carving<br />
* sculpting and casting pieces<br />
and much more that was reaching through the nice process of reading, learning and building together.<br />
<br />
== Glossary ==<br />
<br />
* '''AC-'''Alternating current as produced by the alternator. All thread - USA word for 'threaded' or 'spun' rod or studding<br />
* '''Brake switch''' - A switch used to short-circuit the wires from the alternator so that it stops.<br />
* '''Catalyst''' - A chemical used to make the polyester resin set solid. Catalyst reacts with 'accelerator' already present in the resin mix. <br />
The heat of reaction sets the polyester.<br />
* '''Cavalier''' - A make of car. The cavalier in the UK is not the same as the Cavalier in the USA but both have useful wheel hubs.<br />
* '''DC - direct current''' with a positive and a negative side, as in battery circuits.<br />
* '''Diameter''' - The distance from one side of a circle to another. The width of a disk right across the middle.<br />
* '''Phase''' - The timing of the cyclical alternation of voltage in a circuit. Different phases will peak at different times.<br />
* '''Polyester''' - A type of resin used in fibreglass work. Also suitable for making castings.<br />
* '''Power''' - the rate of delivery of energy<br />
* '''Rectifier''' - A semiconductor device that turns AC into DC for charging the battery.<br />
* '''Root''' - The widest part of the blade near to the hub at the center of the rotor.<br />
* '''Rotor''' - A rotating part. Magnet rotors are the steel diskscarrying the magnets past the stator. Rotor blades are the 'propeller' <br />
driven by the wind and driving the magnet rotors.<br />
* '''Soldering''' - A method for making electrical connections between wires using a hot 'iron' and coating everything with molten solder.<br />
* '''Drag''' - A force exerted by the wind on an object. Drag is parallel to the wind direction at the object. (see Lift) <br />
* '''Stator''' - An assembly of coils embedded in a slab of resin to form part of the alternator. The magnets induce a voltage in the coils and we can use this to charge a battery.<br />
* '''Drop''' - Used here to describe a certain measurement of the shape of a windmill blade. The 'drop' affects the angle of<br />
the blade to the wind. Styrene monomer - A nasty smelling solvent in the polyester resin mix.<br />
* '''Flux''' - The 'stuff' of magnetism. Similar to 'current' in electricity. It can be visualized as 'lines' coming out of one pole and <br />
returning to the other.<br />
* '''Furling''' - A protective action that reduces exposure to violent winds by facing the blades away from them.<br />
* '''Jig''' - A device used to hold the magnets in place before setting them in resin.<br />
* '''Leading edge''' - The edge of a blade that would strike an object placed in its path as the rotor spins.<br />
* '''Lift''' - A force exerted by the wind on an object. Lift is at right angles to the wind direction at the object. (see Drag)<br />
* '''Mold''' - A shaped container in which resin castings are formed. The mould can be discarded after the casting has set.<br />
* '''Multimeter''' - A versatile electrical test instrument, used to measure voltage, current and other parameters.<br />
* '''Neodymium''' - The name given to a type of permanent magnet containing neodymium, iron and boron. These magnets are very strong and <br />
getting cheaper all the time.<br />
* '''Offset''' - An eccentric position, off centre.<br />
* '''Talcum powder'''- A cheap filler powder used to thicken the resin and slow its reaction (prevent it overheating).<br />
* '''Tail''' - A projecting vane mounted on a boom at the back ofthe windmill used to steer it into or out of the wind automatically.<br />
* '''Tap''' - a tool for making thread inside holes so you can fit a screw into the hole.<br />
* '''Thrust''' - The force of the wind pushing the machine backwards.<br />
* '''Tower''' - The mast supporting the windmill.<br />
* '''Trailing edge''' - The blade edge furthest from the leading edge. The trailing edge is sharpened, so as to release the passing <br />
air without turbulence.<br />
* '''Wedges''' - Tapered pieces of wood used to build up the blade thickness and increase its angle to the wind near the root.<br />
* '''Work-piece''' - The piece of wood or metal being shaped in the workshop.<br />
* '''Yaw bearing''' - the swivel at the top of the tower on which the windmill is mounted. The yaw bearing allows the windmill to face the wind.<br />

== The space == <br />
<br />
=== The Foundry ===<br />
The Foundry is a non-profit organization based in a previously abandoned GaliZA village. It functions both as a residency and as a project space. It subscribes to the ideals of self-organization, and has the following three objectives:<br />
1. Organizing activities in the field of the arts, science and humanities outside of traditional institutions, focusing on critical discourse.<br />
2. Promoting the exchange of ideas and intellectual collaboration outside of the constraints imposed by state and market.<br />
3. Increasing self-sufficiency, sustainability, and an awareness of the environment using appropriate technology and open source as main resources.<br />
Taking into account this context, our aim is to reinforce the capacity to generate networks flowing from rural to urban context supporting non hierarchy and democratic exchanges of knowledge and practices that can enable new and sustainable models within rural contexts. According to that we consider that the new trans-disciplinary creative sectors in which we are entangled can have a huge and positive impact in the creation of this new paradigm. https://bravosfoundry.com/<br />
Aside from that, there is thematic focus on transdisciplinarity, transfeminism and post-humanism. While this focus is not adequately grasped by identity-political categories like race or gender, we hope it leads to the subversion of hegemonic structures inscribed in the binarisms upholding many of these categories. Our interest lies in the development of tools and technologies that subvert contemporary structures of domination, exploitation and marginalization, not in those that reproduce it.<br />
We seek to develop a more sustainable environment by opening up our practices based on a free culture framework, generating networks and interest around them, enabling a flow of exchange of innovation across creative sectors focusing on revaluation of rural contexts and its knowledge heritage.<br />

=== '''Section 2, involves the construction of '''the alternator''' parts using the devices from the section 1.''' ===<br />
<br />
'''Alternator'''<br />
Each magnet rotor is a steel disk with 12 magnets placed on it and set in resin. The magnets are each 50 x 50 x 20 mm, and they only just fit on the disk. The idea is to achieve the maximum amount of flux in a given space.<br />
The turbine runs at 650 rpm for 400W output, so the centrifugal force on the magnets is 60 times the force of gravity. To prevent them flying off, the resin casting needs to be reinforced. Stainless steel wire rope is placed around the outside of the magnets to hold the casting together at high rpm. We use stainless because it is non-magnetic, or at least less magnetic than normal steel wire rope. <br />
<br />
You will wind the coils that produce the output power and cast them in resin to form a stator between the two magnet rotors. Photos of the final pieces here <br />

[[File:prod05.jpg|300px]] <br />
<br />
Step - Generator, rotor: Preparation of the wheel hub.<br />
<br />
[[File:frame10.jpg|300px]]<br />
<br />
'''The wheel hub'''<br />
<br />
You can find a used car rear wheel hub (Golf, Toyota, etc.) that has a simple way to<br />
attach the axle, or alternatively buy a trailer hubs online new at low cost.<br />
PCD or ‘pitch circle diameter' is the diameter of the circle of the hole pattern in the<br />
hub, and usually this will be 100mm for a car wheel hub, or 4 inches for a trailer hub.<br />
Car hubs may have a brake-drum that you do not need. This can be removed using a<br />
cutting disk on a grinder. The simplest approach is to make four straight cuts around<br />
the four holes in the front, leaving a square surface to which you mount the magnet<br />
rotors. These photos show a golf rear wheel hub – first the brake-drum being cut, and<br />
then the finished hub after cutting off the drum.A typical rear wheel car hub with a <br />
flange on the back end of the stub shaft that can reused to mount it.<br />
Trailer hubs on the other hand are rather basic quality, and the bearings may be too<br />
cheap for long term use, but they are readily available items that can be purchased<br />
online as new. The drawings below (from autow.com) show a typical hub and stub<br />
axle which are bought separately.<br />
You need to be ready to replace the bearings with a named brand (such as SKF). It’s<br />
easy to replace the inner cones and rollers but the outer shells need to be knocked<br />
gently out of the hub with a suitable drift. Keep them straight by tapping evenly on<br />
opposite sides, and take care not to scratch the seating.<br />

Step - Generator, rotor: PreStep<br />
<br />
=== Section 4, involves the craving of the blades and the welding of the base for the turbine generator. ===<br />
<br />
4.1 Making the blades <br />
The drawknife is useful for thicker chunks of wood, and for cutting down into a hollow. <br />
It can make a nice smooth job of the root of the blade, whereas the plane will work better <br />
where you need a very straight finish.<br />
<br />
'''Marking the stations.'''<br />
<br />
Place the blade with its best edge toward you on its upper surface. This will actually<br />
become the back or ‘downwind’ side of the finished blade.<br />
(Most of the front or windward side is to be cut off, so defects on this underneath side<br />
are not important.)<br />
<br />
The root of the blade will be on your right, the tip at the left, 1000 mm from the root<br />
(near the left end).<br />
<br />
Measure from the root, and mark four stations.<br />
Station A at 75mm<br />
Station B at 150 mm<br />
Station C at 500 mm<br />
The Tip at 1000 mm.<br />
<br />
<br />
At each station draw a line right around the workpiece using a square.<br />
<br />
[[File:01tur.jpeg|400px]]<br />
<br />
<br />
'''Tapering the blade'''<br />
The width of the blade tapers down from full size at station C to 55 mm wide at the<br />
tip. Mark the 55 mm tip width, measuring from the leading edge side. Draw a line<br />
though your mark to the trailing edge side at C station and cut off a triangular piece so<br />
as to achieve the correct tapered shape for the blade. Any knots in the triangular<br />
off cut do not matter as this piece is discarded. Try to make this a "square" cut,<br />
perpendicular to the back surface of the blade.<br />
You can do this with a circular saw, or by cross-cutting and shaving as described<br />
above.<br />
<br />
<br />
[[File:02tur.jpeg|400px]]<br />
<br />
'''Marking the leading and trailing edges'''<br />
The next step is to cut the windward face of the blade. This face is defined by the<br />
leading and trailing edge lines of the blade. These lines need to be marked with<br />
reference to the back face of the wood which has been uppermost in the previous<br />
operation.<br />
<br />
Turn the wood over. Start by drawing two diagonal lines between stations A and B<br />
on the front or windward side (see below). One is on the front face and the other on<br />
the trailing edge which is now toward you. <br />
<br />
[[File:03tur.jpeg|400px]]<br />
<br />
<br />
Now draw the leading edge line as shown below, <br />
from station B, down to 16mm(from the back) at station C, then continuing to the tip at<br />
7mm from the back.<br />
<br />
[[File:04tur.jpeg|400px]]<br />
<br />
<br />
(This drawing does not show the extra bit beyond the tip which may remain <br />
in your actual workpiece.)<br />
<br />
Measurements are summarised in this table below. Heights are from the back of the<br />
blade which will then rest on the bench. Remove the wood above this height. "Full"<br />
refers to the full thickness of the original piece of wood you are using.<br />
<br />
<br />
<br />
[[File:05tur.jpeg|400px]]<br />
<br />
<br />
'''The trailing''' <br />
The trailing edge line starts at the bottom of the diagonal line at station B, and <br />
rises to 5mm at C, continuing at 5 mm to the tip. This view below shows the wood <br />
already removed between the two lines to form the windward face of the blade.<br />
<br />
<br />
[[File:06tur.png|400px]]<br />
<br />
<br />
Carve this flat windward face between the 2 lines. Take care that the edges are<br />
straight, following the lines. The best tool to use for finishing the outer part of the<br />
blade is a plane, to give a smooth, straight finish. You may need to work the plane at<br />
45 degrees to the workpiece, sliding partly sideways, to form the hollow shape at<br />
station C.<br />
<br />
This step is completed when you can place a ruler across the face between the leading<br />
and trailing edge lines and there is no ‘hump’ in the middle. Fill any chips or small<br />
hollows with wood filler. If there are any serious errors, or large knots that weaken<br />
the blade then it may have to be discarded.<br />
Check the “drop” using a level as a reference. Clamp the wood so that the root part<br />
sits level, and measure the difference in level between the leading and trailing edges.<br />
The difference or “drop” should be 11 mm at the 500 mm mid-point, and 2 mm at the<br />
tip.<br />

"Pedagoxías do vento e das estrelas. As relacións sociais ás que (nunca estabamos destinados a) sobrevivir, tamén vivimos nos nosos corpos dolorosamente, e Audre Lorde non está aquí para lembrarnos esta lección, salvo na medida en que está presente no vento pedagóxico.<br />
Pero o vento é o noso mestre (74). -Alexis Pauline Gumbs "<br />
<br />
O principal obxectivo deste evento é prototipar un xerador eólico a pequena escala para camiñar xuntos cara á autosuficiencia neste campo.<br />
Temos o pracer de comunicarvos que do 16 ao 23 de outubro Biotranslab de Pin e The Foundry establecen unha colaboración para levar a cabo o evento Eco (i) Logic Queer Energy harvesting. O proxecto é posible grazas ao apoio de GOSH, unha rede para desenvolver e difundir proxectos baseados en hardware de código aberto para a ciencia.<br />
<br />
EcoLoxicas Queer para a captación de enerxía eolica. <br />
O evento ten como obxectivo abordar a falta de mulleres, queer, trans e diversidade nos ámbitos tecnolóxicos en xeral e do hacking máis concretamente. Pero aínda máis, pretende crear unha comunidade que avalía criticamente as narrativas hexemónicas arredor das tecnoloxías, os aspectos de modernidade dos seus supostos occidentais subliñados e as súas inflexións capitalistas inherentes, entre outros.<br />
O obxectivo principal do evento é desenvolver kits que se centren na interacción co medio natural no ámbito da enerxía.. o obxectivo principal pasa pola captación de enerxía do medio natural, a través dos aeroxeradores. Estes kits de enerxía serán escalables e poderán utilizarse tanto como material pedagóxico como para instalar centrais eléctricas específicas do sitio en diferentes sitios tamén. Este traballo ten un compoñente contrainfraestrutural: unha posible consecuencia sería capacitar ás persoas para xerar a súa propia enerxía en lugar de depender de grandes empresas e moitas veces extractivas.<br />

''Pedagogies of the Wind and Stars. The social relations that we (were never meant to) survive, also live in our bodies painfully, and Audre Lorde is not here to remind us of this lesson herself, except in as much that she is present in the pedagogical wind. But wind is our teacher (74). -Alexis Pauline Gumbs'' from the book Mapping Queer Space(s) of Praxis and Pedagogy <br />
Editors: Elizabeth McNeil, James E. Wermers, Joshua O. Lunn'' <br />
<br />
We have the pleasure to communicate you that from 16 to 29 of October Pin Biotranslab, Casa do Río e The Foundry establishes a collaboration to run the event Eco (i) Logic Queer Energy harvesting. The project is possible thanks to the support of GOSH, an network for develop and disseminate projects based on Open Source hardware for Science.<br />
<br />
'''Eco (i) Logic Queer Energy harvesting''' <br />
The event aims at addressing the lack of women, queer, trans and diversity in technological fields in general and hacking more specifically. But even more so, it aims at creating a community that critically assesses the hegemonic narratives around technologies, the modernity aspects of its underlining Western assumptions and its inherent capitalist inflections, among others.<br />
The main purpose of the event is to develop kits that focus on interacting with the natural environment on the field of energy.. the main objective lies on harvesting energy of the natural environment, through wind turbines. These power kits will be scalable and can be used both as pedagogical material and to set up site-specific power plants in different sites as well. There is a counter-infrastructural component to this work: one possible consequence would be to empower people to generate their own energy instead of relying on large and often extractive companies.<br />
<br />
== Introduction and values of the process ==<br />
<br />
Here starts the documentation of the long process of the prototyping the Hugh Piggott The Piggott Turbine – Wind Empowerment model of an Open source wind turbine. We were changing a bit the goals of the event from developing small kits to going to build the real 2m size wind turbine to provide energy to the rural regional areas we were working on. In that specific event we were working at The Foundry a nice project and association that we have settled on the north part of GaliZA into the Northwest of Spain.<br />
<br />
During the event many things have been activated between the doers and the visitors; In general It was a wondering experience full of new things to study, learn, doing and understand together. <br />
<br />
We chose this model because It was full of layers of interest on the levels of learning, understanding and making it, here some levels mixed up with layers: <br />
<br />
first to all is one of the ones that is '''open source''' or at least has the option to access the full documentation.<br />
<br />
really '''rich on the pedagogical level''', we were really learning through the complete building of the generator itself, about many topics as :<br />
* electromagnetism<br />
* mathematics<br />
* geometry<br />
* electronics<br />
* AC-DC<br />
* welding<br />
* wood carving<br />
* sculpting and casting pieces<br />
and much more that was reaching through the nice process of reading, learning and building together.<br />
<br />
== Glossary ==<br />
<br />
* '''AC-'''Alternating current as produced by the alternator. All thread - USA word for 'threaded' or 'spun' rod or studding<br />
* '''Brake switch''' - A switch used to short-circuit the wires from the alternator so that it stops.<br />
* '''Catalyst''' - A chemical used to make the polyester resin set solid. Catalyst reacts with 'accelerator' already present in the resin mix. <br />
The heat of reaction sets the polyester.<br />
* '''Cavalier''' - A make of car. The cavalier in the UK is not the same as the Cavalier in the USA but both have useful wheel hubs.<br />
* '''DC - direct current''' with a positive and a negative side, as in battery circuits.<br />
* '''Diameter''' - The distance from one side of a circle to another. The width of a disk right across the middle.<br />
* '''Phase''' - The timing of the cyclical alternation of voltage in a circuit. Different phases will peak at different times.<br />
* '''Polyester''' - A type of resin used in fibreglass work. Also suitable for making castings.<br />
* '''Power''' - the rate of delivery of energy<br />
* '''Rectifier''' - A semiconductor device that turns AC into DC for charging the battery.<br />
* '''Root''' - The widest part of the blade near to the hub at the center of the rotor.<br />
* '''Rotor''' - A rotating part. Magnet rotors are the steel diskscarrying the magnets past the stator. Rotor blades are the 'propeller' <br />
driven by the wind and driving the magnet rotors.<br />
* '''Soldering''' - A method for making electrical connections between wires using a hot 'iron' and coating everything with molten solder.<br />
* '''Drag''' - A force exerted by the wind on an object. Drag is parallel to the wind direction at the object. (see Lift) <br />
* '''Stator''' - An assembly of coils embedded in a slab of resin to form part of the alternator. The magnets induce a voltage in the coils and we can use this to charge a battery.<br />
* '''Drop''' - Used here to describe a certain measurement of the shape of a windmill blade. The 'drop' affects the angle of<br />
the blade to the wind. Styrene monomer - A nasty smelling solvent in the polyester resin mix.<br />
* '''Flux''' - The 'stuff' of magnetism. Similar to 'current' in electricity. It can be visualized as 'lines' coming out of one pole and <br />
returning to the other.<br />
* '''Furling''' - A protective action that reduces exposure to violent winds by facing the blades away from them.<br />
* '''Jig''' - A device used to hold the magnets in place before setting them in resin.<br />
* '''Leading edge''' - The edge of a blade that would strike an object placed in its path as the rotor spins.<br />
* '''Lift''' - A force exerted by the wind on an object. Lift is at right angles to the wind direction at the object. (see Drag)<br />
* '''Mold''' - A shaped container in which resin castings are formed. The mould can be discarded after the casting has set.<br />
* '''Multimeter''' - A versatile electrical test instrument, used to measure voltage, current and other parameters.<br />
* '''Neodymium''' - The name given to a type of permanent magnet containing neodymium, iron and boron. These magnets are very strong and <br />
getting cheaper all the time.<br />
* '''Offset''' - An eccentric position, off centre.<br />
* '''Talcum powder'''- A cheap filler powder used to thicken the resin and slow its reaction (prevent it overheating).<br />
* '''Tail''' - A projecting vane mounted on a boom at the back ofthe windmill used to steer it into or out of the wind automatically.<br />
* '''Tap''' - a tool for making thread inside holes so you can fit a screw into the hole.<br />
* '''Thrust''' - The force of the wind pushing the machine backwards.<br />
* '''Tower''' - The mast supporting the windmill.<br />
* '''Trailing edge''' - The blade edge furthest from the leading edge. The trailing edge is sharpened, so as to release the passing <br />
air without turbulence.<br />
* '''Wedges''' - Tapered pieces of wood used to build up the blade thickness and increase its angle to the wind near the root.<br />
* '''Work-piece''' - The piece of wood or metal being shaped in the workshop.<br />
* '''Yaw bearing''' - the swivel at the top of the tower on which the windmill is mounted. The yaw bearing allows the windmill to face the wind.<br />

== The space == <br />
<br />
=== The Foundry ===<br />
The Foundry is a non-profit organization based in a previously abandoned GaliZA village. It functions both as a residency and as a project space. It subscribes to the ideals of self-organization, and has the following three objectives:<br />
1. Organizing activities in the field of the arts, science and humanities outside of traditional institutions, focusing on critical discourse.<br />
2. Promoting the exchange of ideas and intellectual collaboration outside of the constraints imposed by state and market.<br />
3. Increasing self-sufficiency, sustainability, and an awareness of the environment using appropriate technology and open source as main resources.<br />
Taking into account this context, our aim is to reinforce the capacity to generate networks flowing from rural to urban context supporting non hierarchy and democratic exchanges of knowledge and practices that can enable new and sustainable models within rural contexts. According to that we consider that the new trans-disciplinary creative sectors in which we are entangled can have a huge and positive impact in the creation of this new paradigm. https://bravosfoundry.com/<br />
Aside from that, there is thematic focus on transdisciplinarity, transfeminism and post-humanism. While this focus is not adequately grasped by identity-political categories like race or gender, we hope it leads to the subversion of hegemonic structures inscribed in the binarisms upholding many of these categories. Our interest lies in the development of tools and technologies that subvert contemporary structures of domination, exploitation and marginalization, not in those that reproduce it.<br />
We seek to develop a more sustainable environment by opening up our practices based on a free culture framework, generating networks and interest around them, enabling a flow of exchange of innovation across creative sectors focusing on revaluation of rural contexts and its knowledge heritage.<br />

=== '''Section 2, involves the construction of '''the alternator''' parts using the devices from the section 1.''' ===<br />
<br />
'''Alternator'''<br />
Each magnet rotor is a steel disk with 12 magnets placed on it and set in resin. The magnets are each 50 x 50 x 20 mm, and they only just fit on the disk. The idea is to achieve the maximum amount of flux in a given space.<br />
The turbine runs at 650 rpm for 400W output, so the centrifugal force on the magnets is 60 times the force of gravity. To prevent them flying off, the resin casting needs to be reinforced. Stainless steel wire rope is placed around the outside of the magnets to hold the casting together at high rpm. We use stainless because it is non-magnetic, or at least less magnetic than normal steel wire rope. <br />
<br />
You will wind the coils that produce the output power and cast them in resin to form a stator between the two magnet rotors. Photos of the final pieces here <br />

[[File:prod05.jpg|300px]] <br />
<br />
Step - Generator, rotor: Preparation of the wheel hub.<br />
<br />
[[File:frame10.jpg|300px]]<br />
<br />
'''The wheel hub'''<br />
<br />
You can find a used car rear wheel hub (Golf, Toyota, etc.) that has a simple way to<br />
attach the axle, or alternatively buy a trailer hubs online new at low cost.<br />
PCD or ‘pitch circle diameter' is the diameter of the circle of the hole pattern in the<br />
hub, and usually this will be 100mm for a car wheel hub, or 4 inches for a trailer hub.<br />
Car hubs may have a brake-drum that you do not need. This can be removed using a<br />
cutting disk on a grinder. The simplest approach is to make four straight cuts around<br />
the four holes in the front, leaving a square surface to which you mount the magnet<br />
rotors. These photos show a golf rear wheel hub – first the brake-drum being cut, and<br />
then the finished hub after cutting off the drum.A typical rear wheel car hub with a <br />
flange on the back end of the stub shaft that can reused to mount it.<br />
Trailer hubs on the other hand are rather basic quality, and the bearings may be too<br />
cheap for long term use, but they are readily available items that can be purchased<br />
online as new. The drawings below (from autow.com) show a typical hub and stub<br />
axle which are bought separately.<br />
You need to be ready to replace the bearings with a named brand (such as SKF). It’s<br />
easy to replace the inner cones and rollers but the outer shells need to be knocked<br />
gently out of the hub with a suitable drift. Keep them straight by tapping evenly on<br />
opposite sides, and take care not to scratch the seating.<br />

=== Section 4, involves the craving of the blades and the welding of the base for the turbine generator. ===<br />
<br />
4.1 Making the blades <br />
The drawknife is useful for thicker chunks of wood, and for cutting down into a hollow. <br />
It can make a nice smooth job of the root of the blade, whereas the plane will work better <br />
where you need a very straight finish.<br />
<br />
'''Marking the stations.'''<br />
<br />
Place the blade with its best edge toward you on its upper surface. This will actually<br />
become the back or ‘downwind’ side of the finished blade.<br />
(Most of the front or windward side is to be cut off, so defects on this underneath side<br />
are not important.)<br />
<br />
The root of the blade will be on your right, the tip at the left, 1000 mm from the root<br />
(near the left end).<br />
<br />
Measure from the root, and mark four stations.<br />
Station A at 75mm<br />
Station B at 150 mm<br />
Station C at 500 mm<br />
The Tip at 1000 mm.<br />
<br />
<br />
At each station draw a line right around the workpiece using a square.<br />
<br />
[[File:01tur.jpeg|400px]]<br />
<br />
<br />
'''Tapering the blade'''<br />
The width of the blade tapers down from full size at station C to 55 mm wide at the<br />
tip. Mark the 55 mm tip width, measuring from the leading edge side. Draw a line<br />
though your mark to the trailing edge side at C station and cut off a triangular piece so<br />
as to achieve the correct tapered shape for the blade. Any knots in the triangular<br />
off cut do not matter as this piece is discarded. Try to make this a "square" cut,<br />
perpendicular to the back surface of the blade.<br />
You can do this with a circular saw, or by cross-cutting and shaving as described<br />
above.<br />
<br />
<br />
[[File:02tur.jpeg|400px]]<br />
<br />
'''Marking the leading and trailing edges'''<br />
The next step is to cut the windward face of the blade. This face is defined by the<br />
leading and trailing edge lines of the blade. These lines need to be marked with<br />
reference to the back face of the wood which has been uppermost in the previous<br />
operation.<br />
<br />
Turn the wood over. Start by drawing two diagonal lines between stations A and B<br />
on the front or windward side (see below). One is on the front face and the other on<br />
the trailing edge which is now toward you. <br />
<br />
[[File:03tur.jpeg|400px]]<br />
<br />
<br />
Now draw the leading edge line as shown below, <br />
from station B, down to 16mm(from the back) at station C, then continuing to the tip at<br />
7mm from the back.<br />
<br />
[[File:04tur.jpeg|400px]]<br />
<br />
<br />
(This drawing does not show the extra bit beyond the tip which may remain <br />
in your actual workpiece.)<br />
<br />
Measurements are summarised in this table below. Heights are from the back of the<br />
blade which will then rest on the bench. Remove the wood above this height. "Full"<br />
refers to the full thickness of the original piece of wood you are using.<br />
<br />
<br />
<br />
[[File:05tur.jpeg|400px]]<br />
<br />
<br />
'''The trailing''' <br />
The trailing edge line starts at the bottom of the diagonal line at station B, and <br />
rises to 5mm at C, continuing at 5 mm to the tip. This view below shows the wood <br />
already removed between the two lines to form the windward face of the blade.<br />
<br />
<br />
[[File:06tur.png|400px]]<br />
<br />
<br />
Carve this flat windward face between the 2 lines. Take care that the edges are<br />
straight, following the lines. The best tool to use for finishing the outer part of the<br />
blade is a plane, to give a smooth, straight finish. You may need to work the plane at<br />
45 degrees to the workpiece, sliding partly sideways, to form the hollow shape at<br />
station C.<br />
<br />
This step is completed when you can place a ruler across the face between the leading<br />
and trailing edge lines and there is no ‘hump’ in the middle. Fill any chips or small<br />
hollows with wood filler. If there are any serious errors, or large knots that weaken<br />
the blade then it may have to be discarded.<br />
Check the “drop” using a level as a reference. Clamp the wood so that the root part<br />
sits level, and measure the difference in level between the leading and trailing edges.<br />
The difference or “drop” should be 11 mm at the 500 mm mid-point, and 2 mm at the<br />
tip.<br />
<br />

"Pedagoxías do vento e das estrelas. As relacións sociais ás que (nunca estabamos destinados a) sobrevivir, tamén vivimos nos nosos corpos dolorosamente, e Audre Lorde non está aquí para lembrarnos esta lección, salvo na medida en que está presente no vento pedagóxico.<br />
Pero o vento é o noso mestre (74). -Alexis Pauline Gumbs "<br />
<br />
O principal obxectivo deste evento é prototipar un xerador eólico a pequena escala para camiñar xuntos cara á autosuficiencia neste campo.<br />
Temos o pracer de comunicarvos que do 16 ao 23 de outubro Biotranslab de Pin e The Foundry establecen unha colaboración para levar a cabo o evento Eco (i) Logic Queer Energy harvesting. O proxecto é posible grazas ao apoio de GOSH, unha rede para desenvolver e difundir proxectos baseados en hardware de código aberto para a ciencia.<br />
<br />
EcoLoxicas Queer para a captación de enerxía eolica. <br />
O evento ten como obxectivo abordar a falta de mulleres, queer, trans e diversidade nos ámbitos tecnolóxicos en xeral e do hacking máis concretamente. Pero aínda máis, pretende crear unha comunidade que avalía criticamente as narrativas hexemónicas arredor das tecnoloxías, os aspectos de modernidade dos seus supostos occidentais subliñados e as súas inflexións capitalistas inherentes, entre outros.<br />
O obxectivo principal do evento é desenvolver kits que se centren na interacción co medio natural no ámbito da enerxía.. o obxectivo principal pasa pola captación de enerxía do medio natural, a través dos aeroxeradores. Estes kits de enerxía serán escalables e poderán utilizarse tanto como material pedagóxico como para instalar centrais eléctricas específicas do sitio en diferentes sitios tamén. Este traballo ten un compoñente contrainfraestrutural: unha posible consecuencia sería capacitar ás persoas para xerar a súa propia enerxía en lugar de depender de grandes empresas e moitas veces extractivas.<br />

''Pedagogies of the Wind and Stars. The social relations that we (were never meant to) survive, also live in our bodies painfully, and Audre Lorde is not here to remind us of this lesson herself, except in as much that she is present in the pedagogical wind. But wind is our teacher (74). -Alexis Pauline Gumbs'' from the book Mapping Queer Space(s) of Praxis and Pedagogy <br />
Editors: Elizabeth McNeil, James E. Wermers, Joshua O. Lunn'' <br />
<br />
We have the pleasure to communicate you that from 16 to 29 of October Pin Biotranslab, Casa do Río e The Foundry establishes a collaboration to run the event Eco (i) Logic Queer Energy harvesting. The project is possible thanks to the support of GOSH, an network for develop and disseminate projects based on Open Source hardware for Science.<br />
<br />
'''Eco (i) Logic Queer Energy harvesting''' <br />
The event aims at addressing the lack of women, queer, trans and diversity in technological fields in general and hacking more specifically. But even more so, it aims at creating a community that critically assesses the hegemonic narratives around technologies, the modernity aspects of its underlining Western assumptions and its inherent capitalist inflections, among others.<br />
The main purpose of the event is to develop kits that focus on interacting with the natural environment on the field of energy.. the main objective lies on harvesting energy of the natural environment, through wind turbines. These power kits will be scalable and can be used both as pedagogical material and to set up site-specific power plants in different sites as well. There is a counter-infrastructural component to this work: one possible consequence would be to empower people to generate their own energy instead of relying on large and often extractive companies.<br />
<br />
== Introduction and values of the process ==<br />
<br />
Here starts the documentation of the long process of the prototyping the Hugh Piggott The Piggott Turbine – Wind Empowerment model of an Open source wind turbine. We were changing a bit the goals of the event from developing small kits to going to build the real 2m size wind turbine to provide energy to the rural regional areas we were working on. In that specific event we were working at The Foundry a nice project and association that we have settled on the north part of GaliZA into the Northwest of Spain.<br />
<br />
During the event many things have been activated between the doers and the visitors; In general It was a wondering experience full of new things to study, learn, doing and understand together. <br />
<br />
We chose this model because It was full of layers of interest on the levels of learning, understanding and making it, here some levels mixed up with layers: <br />
<br />
first to all is one of the ones that is '''open source''' or at least has the option to access the full documentation.<br />
<br />
really '''rich on the pedagogical level''', we were really learning through the complete building of the generator itself, about many topics as :<br />
* electromagnetism<br />
* mathematics<br />
* geometry<br />
* electronics<br />
* AC-DC<br />
* welding<br />
* wood carving<br />
* sculpting and casting pieces<br />
and much more that was reaching through the nice process of reading, learning and building together.<br />
<br />
== Glossary ==<br />
<br />
* '''AC-'''Alternating current as produced by the alternator. All thread - USA word for 'threaded' or 'spun' rod or studding<br />
* '''Brake switch''' - A switch used to short-circuit the wires from the alternator so that it stops.<br />
* '''Catalyst''' - A chemical used to make the polyester resin set solid. Catalyst reacts with 'accelerator' already present in the resin mix. <br />
The heat of reaction sets the polyester.<br />
* '''Cavalier''' - A make of car. The cavalier in the UK is not the same as the Cavalier in the USA but both have useful wheel hubs.<br />
* '''DC - direct current''' with a positive and a negative side, as in battery circuits.<br />
* '''Diameter''' - The distance from one side of a circle to another. The width of a disk right across the middle.<br />
* '''Phase''' - The timing of the cyclical alternation of voltage in a circuit. Different phases will peak at different times.<br />
* '''Polyester''' - A type of resin used in fibreglass work. Also suitable for making castings.<br />
* '''Power''' - the rate of delivery of energy<br />
* '''Rectifier''' - A semiconductor device that turns AC into DC for charging the battery.<br />
* '''Root''' - The widest part of the blade near to the hub at the center of the rotor.<br />
* '''Rotor''' - A rotating part. Magnet rotors are the steel diskscarrying the magnets past the stator. Rotor blades are the 'propeller' <br />
driven by the wind and driving the magnet rotors.<br />
* '''Soldering''' - A method for making electrical connections between wires using a hot 'iron' and coating everything with molten solder.<br />
* '''Drag''' - A force exerted by the wind on an object. Drag is parallel to the wind direction at the object. (see Lift) <br />
* '''Stator''' - An assembly of coils embedded in a slab of resin to form part of the alternator. The magnets induce a voltage in the coils and we can use this to charge a battery.<br />
* '''Drop''' - Used here to describe a certain measurement of the shape of a windmill blade. The 'drop' affects the angle of<br />
the blade to the wind. Styrene monomer - A nasty smelling solvent in the polyester resin mix.<br />
* '''Flux''' - The 'stuff' of magnetism. Similar to 'current' in electricity. It can be visualized as 'lines' coming out of one pole and <br />
returning to the other.<br />
* '''Furling''' - A protective action that reduces exposure to violent winds by facing the blades away from them.<br />
* '''Jig''' - A device used to hold the magnets in place before setting them in resin.<br />
* '''Leading edge''' - The edge of a blade that would strike an object placed in its path as the rotor spins.<br />
* '''Lift''' - A force exerted by the wind on an object. Lift is at right angles to the wind direction at the object. (see Drag)<br />
* '''Mold''' - A shaped container in which resin castings are formed. The mould can be discarded after the casting has set.<br />
* '''Multimeter''' - A versatile electrical test instrument, used to measure voltage, current and other parameters.<br />
* '''Neodymium''' - The name given to a type of permanent magnet containing neodymium, iron and boron. These magnets are very strong and <br />
getting cheaper all the time.<br />
* '''Offset''' - An eccentric position, off centre.<br />
* '''Talcum powder'''- A cheap filler powder used to thicken the resin and slow its reaction (prevent it overheating).<br />
* '''Tail''' - A projecting vane mounted on a boom at the back ofthe windmill used to steer it into or out of the wind automatically.<br />
* '''Tap''' - a tool for making thread inside holes so you can fit a screw into the hole.<br />
* '''Thrust''' - The force of the wind pushing the machine backwards.<br />
* '''Tower''' - The mast supporting the windmill.<br />
* '''Trailing edge''' - The blade edge furthest from the leading edge. The trailing edge is sharpened, so as to release the passing <br />
air without turbulence.<br />
* '''Wedges''' - Tapered pieces of wood used to build up the blade thickness and increase its angle to the wind near the root.<br />
* '''Work-piece''' - The piece of wood or metal being shaped in the workshop.<br />
* '''Yaw bearing''' - the swivel at the top of the tower on which the windmill is mounted. The yaw bearing allows the windmill to face the wind.<br />

== The space == <br />
<br />
=== The Foundry ===<br />
The Foundry is a non-profit organization based in a previously abandoned GaliZA village. It functions both as a residency and as a project space. It subscribes to the ideals of self-organization, and has the following three objectives:<br />
1. Organizing activities in the field of the arts, science and humanities outside of traditional institutions, focusing on critical discourse.<br />
2. Promoting the exchange of ideas and intellectual collaboration outside of the constraints imposed by state and market.<br />
3. Increasing self-sufficiency, sustainability, and an awareness of the environment using appropriate technology and open source as main resources.<br />
Taking into account this context, our aim is to reinforce the capacity to generate networks flowing from rural to urban context supporting non hierarchy and democratic exchanges of knowledge and practices that can enable new and sustainable models within rural contexts. According to that we consider that the new trans-disciplinary creative sectors in which we are entangled can have a huge and positive impact in the creation of this new paradigm. https://bravosfoundry.com/<br />
Aside from that, there is thematic focus on transdisciplinarity, transfeminism and post-humanism. While this focus is not adequately grasped by identity-political categories like race or gender, we hope it leads to the subversion of hegemonic structures inscribed in the binarisms upholding many of these categories. Our interest lies in the development of tools and technologies that subvert contemporary structures of domination, exploitation and marginalization, not in those that reproduce it.<br />
We seek to develop a more sustainable environment by opening up our practices based on a free culture framework, generating networks and interest around them, enabling a flow of exchange of innovation across creative sectors focusing on revaluation of rural contexts and its knowledge heritage.<br />

=== '''Section 2, involves the construction of '''the alternator''' parts using the devices from the section 1.''' ===<br />
<br />
'''Alternator'''<br />
Each magnet rotor is a steel disk with 12 magnets placed on it and set in resin. The magnets are each 50 x 50 x 20 mm, and they only just fit on the disk. The idea is to achieve the maximum amount of flux in a given space.<br />
The turbine runs at 650 rpm for 400W output, so the centrifugal force on the magnets is 60 times the force of gravity. To prevent them flying off, the resin casting needs to be reinforced. Stainless steel wire rope is placed around the outside of the magnets to hold the casting together at high rpm. We use stainless because it is non-magnetic, or at least less magnetic than normal steel wire rope. <br />
<br />
You will wind the coils that produce the output power and cast them in resin to form a stator between the two magnet rotors. Photos of the final pieces here <br />

<br />
[[File:prod05.jpg|300px]] <br />
<br />
Step - Generator, rotor: Preparation of the wheel hub.<br />
<br />
[[File:frame10.jpg|300px]]<br />
<br />
'''The wheel hub'''<br />
<br />
You can find a used car rear wheel hub (Golf, Toyota, etc.) that has a simple way to<br />
attach the axle, or alternatively buy a trailer hubs online new at low cost.<br />
PCD or ‘pitch circle diameter' is the diameter of the circle of the hole pattern in the<br />
hub, and usually this will be 100mm for a car wheel hub, or 4 inches for a trailer hub.<br />
Car hubs may have a brake-drum that you do not need. This can be removed using a<br />
cutting disk on a grinder. The simplest approach is to make four straight cuts around<br />
the four holes in the front, leaving a square surface to which you mount the magnet<br />
rotors. These photos show a golf rear wheel hub – first the brake-drum being cut, and<br />
then the finished hub after cutting off the drum.A typical rear wheel car hub with a <br />
flange on the back end of the stub shaft that can reused to mount it.<br />
Trailer hubs on the other hand are rather basic quality, and the bearings may be too<br />
cheap for long term use, but they are readily available items that can be purchased<br />
online as new. The drawings below (from autow.com) show a typical hub and stub<br />
axle which are bought separately.<br />
You need to be ready to replace the bearings with a named brand (such as SKF). It’s<br />
easy to replace the inner cones and rollers but the outer shells need to be knocked<br />
gently out of the hub with a suitable drift. Keep them straight by tapping evenly on<br />
opposite sides, and take care not to scratch the seating.<br />

<br />
=== Section 4, involves the craving of the blades and the welding of the base for the turbine generator. ===<br />
<br />
4.1 Making the blades <br />
The drawknife is useful for thicker chunks of wood, and for cutting down into a hollow. <br />
It can make a nice smooth job of the root of the blade, whereas the plane will work better <br />
where you need a very straight finish.<br />
<br />
'''Marking the stations.'''<br />
<br />
Place the blade with its best edge toward you on its upper surface. This will actually<br />
become the back or ‘downwind’ side of the finished blade.<br />
(Most of the front or windward side is to be cut off, so defects on this underneath side<br />
are not important.)<br />
<br />
The root of the blade will be on your right, the tip at the left, 1000 mm from the root<br />
(near the left end).<br />
<br />
Measure from the root, and mark four stations.<br />
Station A at 75mm<br />
Station B at 150 mm<br />
Station C at 500 mm<br />
The Tip at 1000 mm.<br />
<br />
<br />
At each station draw a line right around the workpiece using a square.<br />
<br />
[[File:01tur.jpeg|400px]]<br />
<br />
<br />
'''Tapering the blade'''<br />
The width of the blade tapers down from full size at station C to 55 mm wide at the<br />
tip. Mark the 55 mm tip width, measuring from the leading edge side. Draw a line<br />
though your mark to the trailing edge side at C station and cut off a triangular piece so<br />
as to achieve the correct tapered shape for the blade. Any knots in the triangular<br />
off cut do not matter as this piece is discarded. Try to make this a "square" cut,<br />
perpendicular to the back surface of the blade.<br />
You can do this with a circular saw, or by cross-cutting and shaving as described<br />
above.<br />
<br />
<br />
[[File:02tur.jpeg|400px]]<br />
<br />
'''Marking the leading and trailing edges'''<br />
The next step is to cut the windward face of the blade. This face is defined by the<br />
leading and trailing edge lines of the blade. These lines need to be marked with<br />
reference to the back face of the wood which has been uppermost in the previous<br />
operation.<br />
<br />
Turn the wood over. Start by drawing two diagonal lines between stations A and B<br />
on the front or windward side (see below). One is on the front face and the other on<br />
the trailing edge which is now toward you. <br />
<br />
[[File:03tur.jpeg|400px]]<br />
<br />
<br />
Now draw the leading edge line as shown below, <br />
from station B, down to 16mm(from the back) at station C, then continuing to the tip at<br />
7mm from the back.<br />
<br />
[[File:04tur.jpeg|400px]]<br />
<br />
<br />
(This drawing does not show the extra bit beyond the tip which may remain <br />
in your actual workpiece.)<br />
<br />
Measurements are summarised in this table below. Heights are from the back of the<br />
blade which will then rest on the bench. Remove the wood above this height. "Full"<br />
refers to the full thickness of the original piece of wood you are using.<br />
<br />
<br />
<br />
[[File:05tur.jpeg|400px]]<br />
<br />
<br />
'''The trailing''' <br />
The trailing edge line starts at the bottom of the diagonal line at station B, and <br />
rises to 5mm at C, continuing at 5 mm to the tip. This view below shows the wood <br />
already removed between the two lines to form the windward face of the blade.<br />
<br />
<br />
[[File:06tur.png|400px]]<br />
<br />
<br />
Carve this flat windward face between the 2 lines. Take care that the edges are<br />
straight, following the lines. The best tool to use for finishing the outer part of the<br />
blade is a plane, to give a smooth, straight finish. You may need to work the plane at<br />
45 degrees to the workpiece, sliding partly sideways, to form the hollow shape at<br />
station C.<br />
<br />
This step is completed when you can place a ruler across the face between the leading<br />
and trailing edge lines and there is no ‘hump’ in the middle. Fill any chips or small<br />
hollows with wood filler. If there are any serious errors, or large knots that weaken<br />
the blade then it may have to be discarded.<br />
Check the “drop” using a level as a reference. Clamp the wood so that the root part<br />
sits level, and measure the difference in level between the leading and trailing edges.<br />
The difference or “drop” should be 11 mm at the 500 mm mid-point, and 2 mm at the<br />
tip.<br />
<br />

"Pedagoxías do vento e das estrelas. As relacións sociais ás que (nunca estabamos destinados a) sobrevivir, tamén vivimos nos nosos corpos dolorosamente, e Audre Lorde non está aquí para lembrarnos esta lección, salvo na medida en que está presente no vento pedagóxico.<br />
Pero o vento é o noso mestre (74). -Alexis Pauline Gumbs "<br />
<br />
O principal obxectivo deste evento é prototipar un xerador eólico a pequena escala para camiñar xuntos cara á autosuficiencia neste campo.<br />
Temos o pracer de comunicarvos que do 16 ao 23 de outubro Biotranslab de Pin e The Foundry establecen unha colaboración para levar a cabo o evento Eco (i) Logic Queer Energy harvesting. O proxecto é posible grazas ao apoio de GOSH, unha rede para desenvolver e difundir proxectos baseados en hardware de código aberto para a ciencia.<br />
<br />
EcoLoxicas Queer para a captación de enerxía eolica. <br />
O evento ten como obxectivo abordar a falta de mulleres, queer, trans e diversidade nos ámbitos tecnolóxicos en xeral e do hacking máis concretamente. Pero aínda máis, pretende crear unha comunidade que avalía criticamente as narrativas hexemónicas arredor das tecnoloxías, os aspectos de modernidade dos seus supostos occidentais subliñados e as súas inflexións capitalistas inherentes, entre outros.<br />
O obxectivo principal do evento é desenvolver kits que se centren na interacción co medio natural no ámbito da enerxía.. o obxectivo principal pasa pola captación de enerxía do medio natural, a través dos aeroxeradores. Estes kits de enerxía serán escalables e poderán utilizarse tanto como material pedagóxico como para instalar centrais eléctricas específicas do sitio en diferentes sitios tamén. Este traballo ten un compoñente contrainfraestrutural: unha posible consecuencia sería capacitar ás persoas para xerar a súa propia enerxía en lugar de depender de grandes empresas e moitas veces extractivas.<br />

''Pedagogies of the Wind and Stars. The social relations that we (were never meant to) survive, also live in our bodies painfully, and Audre Lorde is not here to remind us of this lesson herself, except in as much that she is present in the pedagogical wind.

<br />
We have the pleasure to communicate you that from 16 to 29 of October Pin Biotranslab, Casa do Río e The Foundry establishes a collaboration to run the event Eco (i) Logic Queer Energy harvesting. The project is possible thanks to the support of GOSH, an network for develop and disseminate projects based on Open Source hardware for Science.<br />
<br />
'''Eco (i) Logic Queer Energy harvesting''' <br />
The event aims at addressing the lack of women, queer, trans and diversity in technological fields in general and hacking more specifically. But even more so, it aims at creating a community that critically assesses the hegemonic narratives around technologies, the modernity aspects of its underlining Western assumptions and its inherent capitalist inflections, among others.<br />
The main purpose of the event is to develop kits that focus on interacting with the natural environment on the field of energy.. the main objective lies on harvesting energy of the natural environment, through wind turbines. These power kits will be scalable and can be used both as pedagogical material and to set up site-specific power plants in different sites as well. There is a counter-infrastructural component to this work: one possible consequence would be to empower people to generate their own energy instead of relying on large and often extractive companies.<br />
<br />
== Introduction and values of the process ==<br />
<br />
Here starts the documentation of the long process of the prototyping the Hugh Piggott The Piggott Turbine – Wind Empowerment model of an Open source wind turbine. We were changing a bit the goals of the event from developing small kits to going to build the real 2m size wind turbine to provide energy to the rural regional areas we were working on. In that specific event we were working at The Foundry a nice project and association that we have settled on the north part of GaliZA into the Northwest of Spain.<br />
<br />
During the event many things have been activated between the doers and the visitors; In general It was a wondering experience full of new things to study, learn, doing and understand together. <br />
<br />
We chose this model because It was full of layers of interest on the levels of learning, understanding and making it, here some levels mixed up with layers: <br />
<br />
first to all is one of the ones that is '''open source''' or at least has the option to access the full documentation.<br />
<br />
really '''rich on the pedagogical level''', we were really learning through the complete building of the generator itself, about many topics as :<br />
* electromagnetism<br />
* mathematics<br />
* geometry<br />
* electronics<br />
* AC-DC<br />
* welding<br />
* wood carving<br />
* sculpting and casting pieces<br />
and much more that was reaching through the nice process of reading, learning and building together.<br />
<br />
== Glossary ==<br />
<br />
* '''AC-'''Alternating current as produced by the alternator. All thread - USA word for 'threaded' or 'spun' rod or studding<br />
* '''Brake switch''' - A switch used to short-circuit the wires from the alternator so that it stops.<br />
* '''Catalyst''' - A chemical used to make the polyester resin set solid. Catalyst reacts with 'accelerator' already present in the resin mix. <br />
The heat of reaction sets the polyester.<br />
* '''Cavalier''' - A make of car. The cavalier in the UK is not the same as the Cavalier in the USA but both have useful wheel hubs.<br />
* '''DC - direct current''' with a positive and a negative side, as in battery circuits.<br />
* '''Diameter''' - The distance from one side of a circle to another. The width of a disk right across the middle.<br />
* '''Phase''' - The timing of the cyclical alternation of voltage in a circuit. Different phases will peak at different times.<br />
* '''Polyester''' - A type of resin used in fibreglass work. Also suitable for making castings.<br />
* '''Power''' - the rate of delivery of energy<br />
* '''Rectifier''' - A semiconductor device that turns AC into DC for charging the battery.<br />
* '''Root''' - The widest part of the blade near to the hub at the center of the rotor.<br />
* '''Rotor''' - A rotating part. Magnet rotors are the steel diskscarrying the magnets past the stator. Rotor blades are the 'propeller' <br />
driven by the wind and driving the magnet rotors.<br />
* '''Soldering''' - A method for making electrical connections between wires using a hot 'iron' and coating everything with molten solder.<br />
* '''Drag''' - A force exerted by the wind on an object. Drag is parallel to the wind direction at the object. (see Lift) <br />
* '''Stator''' - An assembly of coils embedded in a slab of resin to form part of the alternator. The magnets induce a voltage in the coils and we can use this to charge a battery.<br />
* '''Drop''' - Used here to describe a certain measurement of the shape of a windmill blade. The 'drop' affects the angle of<br />
the blade to the wind. Styrene monomer - A nasty smelling solvent in the polyester resin mix.<br />
* '''Flux''' - The 'stuff' of magnetism. Similar to 'current' in electricity. It can be visualized as 'lines' coming out of one pole and <br />
returning to the other.<br />
* '''Furling''' - A protective action that reduces exposure to violent winds by facing the blades away from them.<br />
* '''Jig''' - A device used to hold the magnets in place before setting them in resin.<br />
* '''Leading edge''' - The edge of a blade that would strike an object placed in its path as the rotor spins.<br />
* '''Lift''' - A force exerted by the wind on an object. Lift is at right angles to the wind direction at the object. (see Drag)<br />
* '''Mold''' - A shaped container in which resin castings are formed. The mould can be discarded after the casting has set.<br />
* '''Multimeter''' - A versatile electrical test instrument, used to measure voltage, current and other parameters.<br />
* '''Neodymium''' - The name given to a type of permanent magnet containing neodymium, iron and boron. These magnets are very strong and <br />
getting cheaper all the time.<br />
* '''Offset''' - An eccentric position, off centre.<br />
* '''Talcum powder'''- A cheap filler powder used to thicken the resin and slow its reaction (prevent it overheating).<br />
* '''Tail''' - A projecting vane mounted on a boom at the back ofthe windmill used to steer it into or out of the wind automatically.<br />
* '''Tap''' - a tool for making thread inside holes so you can fit a screw into the hole.<br />
* '''Thrust''' - The force of the wind pushing the machine backwards.<br />
* '''Tower''' - The mast supporting the windmill.<br />
* '''Trailing edge''' - The blade edge furthest from the leading edge. The trailing edge is sharpened, so as to release the passing <br />
air without turbulence.<br />
* '''Wedges''' - Tapered pieces of wood used to build up the blade thickness and increase its angle to the wind near the root.<br />
* '''Work-piece''' - The piece of wood or metal being shaped in the workshop.<br />
* '''Yaw bearing''' - the swivel at the top of the tower on which the windmill is mounted. The yaw bearing allows the windmill to face the wind.<br />

== The space == <br />
<br />
=== The Foundry ===<br />
The Foundry is a non-profit organization based in a previously abandoned GaliZA village. It functions both as a residency and as a project space. It subscribes to the ideals of self-organization, and has the following three objectives:<br />
1. Organizing activities in the field of the arts, science and humanities outside of traditional institutions, focusing on critical discourse.<br />
2. Promoting the exchange of ideas and intellectual collaboration outside of the constraints imposed by state and market.<br />
3. Increasing self-sufficiency, sustainability, and an awareness of the environment using appropriate technology and open source as main resources.<br />
Taking into account this context, our aim is to reinforce the capacity to generate networks flowing from rural to urban context supporting non hierarchy and democratic exchanges of knowledge and practices that can enable new and sustainable models within rural contexts. According to that we consider that the new trans-disciplinary creative sectors in which we are entangled can have a huge and positive impact in the creation of this new paradigm. https://bravosfoundry.com/<br />
Aside from that, there is thematic focus on transdisciplinarity, transfeminism and post-humanism. While this focus is not adequately grasped by identity-political categories like race or gender, we hope it leads to the subversion of hegemonic structures inscribed in the binarisms upholding many of these categories. Our interest lies in the development of tools and technologies that subvert contemporary structures of domination, exploitation and marginalization, not in those that reproduce it.<br />
We seek to develop a more sustainable environment by opening up our practices based on a free culture framework, generating networks and interest around them, enabling a flow of exchange of innovation across creative sectors focusing on revaluation of rural contexts and its knowledge heritage.<br />

=== '''Section 2, involves the construction of '''the alternator''' parts using the devices from the section 1.''' ===<br />
<br />
'''Alternator'''<br />
Each magnet rotor is a steel disk with 12 magnets placed on it and set in resin. The magnets are each 50 x 50 x 20 mm, and they only just fit on the disk. The idea is to achieve the maximum amount of flux in a given space.<br />
The turbine runs at 650 rpm for 400W output, so the centrifugal force on the magnets is 60 times the force of gravity. To prevent them flying off, the resin casting needs to be reinforced. Stainless steel wire rope is placed around the outside of the magnets to hold the casting together at high rpm. We use stainless because it is non-magnetic, or at least less magnetic than normal steel wire rope. <br />
<br />
You will wind the coils that produce the output power and cast them in resin to form a stator between the two magnet rotors. Photos of the final pieces here <br />

<br />
[[File:prod05.jpg|300px]] <br />
<br />
Step - Generator, rotor: Preparation of the wheel hub.<br />
<br />
[[File:frame10.jpg|300px]]<br />
<br />
'''The wheel hub'''<br />
<br />
You can find a used car rear wheel hub (Golf, Toyota, etc.) that has a simple way to<br />
attach the axle, or alternatively buy a trailer hubs online new at low cost.<br />
PCD or ‘pitch circle diameter' is the diameter of the circle of the hole pattern in the<br />
hub, and usually this will be 100mm for a car wheel hub, or 4 inches for a trailer hub.<br />
Car hubs may have a brake-drum that you do not need. This can be removed using a<br />
cutting disk on a grinder. The simplest approach is to make four straight cuts around<br />
the four holes in the front, leaving a square surface to which you mount the magnet<br />
rotors. These photos show a golf rear wheel hub – first the brake-drum being cut, and<br />
then the finished hub after cutting off the drum.A typical rear wheel car hub with a <br />
flange on the back end of the stub shaft that can reused to mount it.<br />
Trailer hubs on the other hand are rather basic quality, and the bearings may be too<br />
cheap for long term use, but they are readily available items that can be purchased<br />
online as new. The drawings below (from autow.com) show a typical hub and stub<br />
axle which are bought separately.<br />
You need to be ready to replace the bearings with a named brand (such as SKF). It’s<br />
easy to replace the inner cones and rollers but the outer shells need to be knocked<br />
gently out of the hub with a suitable drift. Keep them straight by tapping evenly on<br />
opposite sides, and take care not to scratch the seating.<br />

Step - Generator, rotor: PreStep<br />
<br />
=== Section 4, involves the craving of the blades and the welding of the base for the turbine generator. ===<br />
<br />
4.1 Making the blades <br />
The drawknife is useful for thicker chunks of wood, and for cutting down into a hollow. <br />
It can make a nice smooth job of the root of the blade, whereas the plane will work better <br />
where you need a very straight finish.<br />
<br />
'''Marking the stations.'''<br />
<br />
Place the blade with its best edge toward you on its upper surface. This will actually<br />
become the back or ‘downwind’ side of the finished blade.<br />
(Most of the front or windward side is to be cut off, so defects on this underneath side<br />
are not important.)<br />
<br />
The root of the blade will be on your right, the tip at the left, 1000 mm from the root<br />
(near the left end).<br />
<br />
Measure from the root, and mark four stations.<br />
Station A at 75mm<br />
Station B at 150 mm<br />
Station C at 500 mm<br />
The Tip at 1000 mm.<br />
<br />
<br />
At each station draw a line right around the workpiece using a square.<br />
<br />
[[File:01tur.jpeg|400px]]<br />
<br />
<br />
'''Tapering the blade'''<br />
The width of the blade tapers down from full size at station C to 55 mm wide at the<br />
tip. Mark the 55 mm tip width, measuring from the leading edge side. Draw a line<br />
though your mark to the trailing edge side at C station and cut off a triangular piece so<br />
as to achieve the correct tapered shape for the blade. Any knots in the triangular<br />
off cut do not matter as this piece is discarded. Try to make this a "square" cut,<br />
perpendicular to the back surface of the blade.<br />
You can do this with a circular saw, or by cross-cutting and shaving as described<br />
above.<br />
<br />
<br />
[[File:02tur.jpeg|400px]]<br />
<br />
'''Marking the leading and trailing edges'''<br />
The next step is to cut the windward face of the blade. This face is defined by the<br />
leading and trailing edge lines of the blade. These lines need to be marked with<br />
reference to the back face of the wood which has been uppermost in the previous<br />
operation.<br />
<br />
Turn the wood over. Start by drawing two diagonal lines between stations A and B<br />
on the front or windward side (see below). One is on the front face and the other on<br />
the trailing edge which is now toward you. <br />
<br />
[[File:03tur.jpeg|400px]]<br />
<br />
<br />
Now draw the leading edge line as shown below, <br />
from station B, down to 16mm(from the back) at station C, then continuing to the tip at<br />
7mm from the back.<br />
<br />
[[File:04tur.jpeg|400px]]<br />
<br />
<br />
(This drawing does not show the extra bit beyond the tip which may remain <br />
in your actual workpiece.)<br />
<br />
Measurements are summarised in this table below. Heights are from the back of the<br />
blade which will then rest on the bench. Remove the wood above this height. "Full"<br />
refers to the full thickness of the original piece of wood you are using.<br />
<br />
<br />
<br />
[[File:05tur.jpeg|400px]]<br />
<br />
<br />
'''The trailing''' <br />
The trailing edge line starts at the bottom of the diagonal line at station B, and <br />
rises to 5mm at C, continuing at 5 mm to the tip. This view below shows the wood <br />
already removed between the two lines to form the windward face of the blade.<br />
<br />
<br />
[[File:06tur.png|400px]]<br />
<br />
<br />
Carve this flat windward face between the 2 lines. Take care that the edges are<br />
straight, following the lines. The best tool to use for finishing the outer part of the<br />
blade is a plane, to give a smooth, straight finish. You may need to work the plane at<br />
45 degrees to the workpiece, sliding partly sideways, to form the hollow shape at<br />
station C.<br />
<br />
This step is completed when you can place a ruler across the face between the leading<br />
and trailing edge lines and there is no ‘hump’ in the middle. Fill any chips or small<br />
hollows with wood filler. If there are any serious errors, or large knots that weaken<br />
the blade then it may have to be discarded.<br />
Check the “drop” using a level as a reference. Clamp the wood so that the root part<br />
sits level, and measure the difference in level between the leading and trailing edges.<br />
The difference or “drop” should be 11 mm at the 500 mm mid-point, and 2 mm at the<br />
tip.<br />
<br />
Step 1 - Propeller: The pattern<br />
Step 2 - Propeller: drawing and cutting of the blades.<br />
Step 3 - Propeller: Sculpture of the lower surface of the blades<br />

"Pedagoxías do vento e das estrelas. As relacións sociais ás que (nunca estabamos destinados a) sobrevivir, tamén vivimos nos nosos corpos dolorosamente, e Audre Lorde non está aquí para lembrarnos esta lección, salvo na medida en que está presente no vento pedagóxico.<br />

<br />
O principal obxectivo deste evento é prototipar un xerador eólico a pequena escala para camiñar xuntos cara á autosuficiencia neste campo.<br />
Temos o pracer de comunicarvos que do 16 ao 23 de outubro Biotranslab de Pin e The Foundry establecen unha colaboración para levar a cabo o evento Eco (i) Logic Queer Energy harvesting. O proxecto é posible grazas ao apoio de GOSH, unha rede para desenvolver e difundir proxectos baseados en hardware de código aberto para a ciencia.<br />
<br />
EcoLoxicas Queer para a captación de enerxía eolica. <br />
O evento ten como obxectivo abordar a falta de mulleres, queer, trans e diversidade nos ámbitos tecnolóxicos en xeral e do hacking máis concretamente. Pero aínda máis, pretende crear unha comunidade que avalía criticamente as narrativas hexemónicas arredor das tecnoloxías, os aspectos de modernidade dos seus supostos occidentais subliñados e as súas inflexións capitalistas inherentes, entre outros.<br />
O obxectivo principal do evento é desenvolver kits que se centren na interacción co medio natural no ámbito da enerxía.. o obxectivo principal pasa pola captación de enerxía do medio natural, a través dos aeroxeradores. Estes kits de enerxía serán escalables e poderán utilizarse tanto como material pedagóxico como para instalar centrais eléctricas específicas do sitio en diferentes sitios tamén. Este traballo ten un compoñente contrainfraestrutural: unha posible consecuencia sería capacitar ás persoas para xerar a súa propia enerxía en lugar de depender de grandes empresas e moitas veces extractivas.<br />

'''Eco (i) Logic Queer Energy harvesting''' <br />
The event aims at addressing the lack of women, queer, trans and diversity in technological fields in general and hacking more specifically. But even more so, it aims at creating a community that critically assesses the hegemonic narratives around technologies, the modernity aspects of its underlining Western assumptions and its inherent capitalist inflections, among others.<br />
The main purpose of the event is to develop kits that focus on interacting with the natural environment on the field of energy.. the main objective lies on harvesting energy of the natural environment, through wind turbines. These power kits will be scalable and can be used both as pedagogical material and to set up site-specific power plants in different sites as well. There is a counter-infrastructural component to this work: one possible consequence would be to empower people to generate their own energy instead of relying on large and often extractive companies.<br />
<br />
== Introduction and values of the process ==<br />
<br />
Here starts the documentation of the long process of the prototyping the Hugh Piggott The Piggott Turbine – Wind Empowerment model of an Open source wind turbine. We were changing a bit the goals of the event from developing small kits to going to build the real 2m size wind turbine to provide energy to the rural regional areas we were working on. In that specific event we were working at The Foundry a nice project and association that we have settled on the north part of GaliZA into the Northwest of Spain.<br />
<br />
During the event many things have been activated between the doers and the visitors; In general It was a wondering experience full of new things to study, learn, doing and understand together. <br />
<br />
We chose this model because It was full of layers of interest on the levels of learning, understanding and making it, here some levels mixed up with layers: <br />
<br />
first to all is one of the ones that is '''open source''' or at least has the option to access the full documentation.<br />
<br />
really '''rich on the pedagogical level''', we were really learning through the complete building of the generator itself, about many topics as :<br />
* electromagnetism<br />
* mathematics<br />
* geometry<br />
* electronics<br />
* AC-DC<br />
* welding<br />
* wood carving<br />
* sculpting and casting pieces<br />
and much more that was reaching through the nice process of reading, learning and building together.<br />
<br />
== Glossary ==<br />
<br />
* '''AC-'''Alternating current as produced by the alternator. All thread - USA word for 'threaded' or 'spun' rod or studding<br />
* '''Brake switch''' - A switch used to short-circuit the wires from the alternator so that it stops.<br />
* '''Catalyst''' - A chemical used to make the polyester resin set solid. Catalyst reacts with 'accelerator' already present in the resin mix. <br />
The heat of reaction sets the polyester.<br />
* '''Cavalier''' - A make of car. The cavalier in the UK is not the same as the Cavalier in the USA but both have useful wheel hubs.<br />
* '''DC - direct current''' with a positive and a negative side, as in battery circuits.<br />
* '''Diameter''' - The distance from one side of a circle to another. The width of a disk right across the middle.<br />
* '''Phase''' - The timing of the cyclical alternation of voltage in a circuit. Different phases will peak at different times.<br />
* '''Polyester''' - A type of resin used in fibreglass work. Also suitable for making castings.<br />
* '''Power''' - the rate of delivery of energy<br />
* '''Rectifier''' - A semiconductor device that turns AC into DC for charging the battery.<br />
* '''Root''' - The widest part of the blade near to the hub at the center of the rotor.<br />
* '''Rotor''' - A rotating part. Magnet rotors are the steel diskscarrying the magnets past the stator. Rotor blades are the 'propeller' <br />
driven by the wind and driving the magnet rotors.<br />
* '''Soldering''' - A method for making electrical connections between wires using a hot 'iron' and coating everything with molten solder.<br />
* '''Drag''' - A force exerted by the wind on an object. Drag is parallel to the wind direction at the object. (see Lift) <br />
* '''Stator''' - An assembly of coils embedded in a slab of resin to form part of the alternator. The magnets induce a voltage in the coils and we can use this to charge a battery.<br />
* '''Drop''' - Used here to describe a certain measurement of the shape of a windmill blade. The 'drop' affects the angle of<br />
the blade to the wind. Styrene monomer - A nasty smelling solvent in the polyester resin mix.<br />
* '''Flux''' - The 'stuff' of magnetism. Similar to 'current' in electricity. It can be visualized as 'lines' coming out of one pole and <br />
returning to the other.<br />
* '''Furling''' - A protective action that reduces exposure to violent winds by facing the blades away from them.<br />
* '''Jig''' - A device used to hold the magnets in place before setting them in resin.<br />
* '''Leading edge''' - The edge of a blade that would strike an object placed in its path as the rotor spins.<br />
* '''Lift''' - A force exerted by the wind on an object. Lift is at right angles to the wind direction at the object. (see Drag)<br />
* '''Mold''' - A shaped container in which resin castings are formed. The mould can be discarded after the casting has set.<br />
* '''Multimeter''' - A versatile electrical test instrument, used to measure voltage, current and other parameters.<br />
* '''Neodymium''' - The name given to a type of permanent magnet containing neodymium, iron and boron. These magnets are very strong and <br />
getting cheaper all the time.<br />
* '''Offset''' - An eccentric position, off centre.<br />
* '''Talcum powder'''- A cheap filler powder used to thicken the resin and slow its reaction (prevent it overheating).<br />
* '''Tail''' - A projecting vane mounted on a boom at the back ofthe windmill used to steer it into or out of the wind automatically.<br />
* '''Tap''' - a tool for making thread inside holes so you can fit a screw into the hole.<br />
* '''Thrust''' - The force of the wind pushing the machine backwards.<br />
* '''Tower''' - The mast supporting the windmill.<br />
* '''Trailing edge''' - The blade edge furthest from the leading edge. The trailing edge is sharpened, so as to release the passing <br />
air without turbulence.<br />
* '''Wedges''' - Tapered pieces of wood used to build up the blade thickness and increase its angle to the wind near the root.<br />
* '''Work-piece''' - The piece of wood or metal being shaped in the workshop.<br />
* '''Yaw bearing''' - the swivel at the top of the tower on which the windmill is mounted. The yaw bearing allows the windmill to face the wind.<br />

== The space == <br />
<br />
=== The Foundry ===<br />
The Foundry is a non-profit organization based in a previously abandoned GaliZA village. It functions both as a residency and as a project space. It subscribes to the ideals of self-organization, and has the following three objectives:<br />
1. Organizing activities in the field of the arts, science and humanities outside of traditional institutions, focusing on critical discourse.<br />
2. Promoting the exchange of ideas and intellectual collaboration outside of the constraints imposed by state and market.<br />
3. Increasing self-sufficiency, sustainability, and an awareness of the environment using appropriate technology and open source as main resources.<br />
Taking into account this context, our aim is to reinforce the capacity to generate networks flowing from rural to urban context supporting non hierarchy and democratic exchanges of knowledge and practices that can enable new and sustainable models within rural contexts. According to that we consider that the new trans-disciplinary creative sectors in which we are entangled can have a huge and positive impact in the creation of this new paradigm. https://bravosfoundry.com/<br />
Aside from that, there is thematic focus on transdisciplinarity, transfeminism and post-humanism. While this focus is not adequately grasped by identity-political categories like race or gender, we hope it leads to the subversion of hegemonic structures inscribed in the binarisms upholding many of these categories. Our interest lies in the development of tools and technologies that subvert contemporary structures of domination, exploitation and marginalization, not in those that reproduce it.<br />
We seek to develop a more sustainable environment by opening up our practices based on a free culture framework, generating networks and interest around them, enabling a flow of exchange of innovation across creative sectors focusing on revaluation of rural contexts and its knowledge heritage.<br />

=== '''Section 2, involves the construction of '''the alternator''' parts using the devices from the section 1.''' ===<br />
<br />
'''Alternator'''<br />
Each magnet rotor is a steel disk with 12 magnets placed on it and set in resin. The magnets are each 50 x 50 x 20 mm, and they only just fit on the disk. The idea is to achieve the maximum amount of flux in a given space.<br />
The turbine runs at 650 rpm for 400W output, so the centrifugal force on the magnets is 60 times the force of gravity. To prevent them flying off, the resin casting needs to be reinforced. Stainless steel wire rope is placed around the outside of the magnets to hold the casting together at high rpm. We use stainless because it is non-magnetic, or at least less magnetic than normal steel wire rope. <br />
<br />
You will wind the coils that produce the output power and cast them in resin to form a stator between the two magnet rotors. Photos of the final pieces here <br />

<br />
[[File:prod05.jpg|300px]] <br />
<br />
Step - Generator, rotor: Preparation of the wheel hub.<br />
<br />
[[File:frame10.jpg|300px]]<br />
<br />
'''The wheel hub'''<br />
<br />
You can find a used car rear wheel hub (Golf, Toyota, etc.) that has a simple way to<br />
attach the axle, or alternatively buy a trailer hubs online new at low cost.<br />
PCD or ‘pitch circle diameter' is the diameter of the circle of the hole pattern in the<br />
hub, and usually this will be 100mm for a car wheel hub, or 4 inches for a trailer hub.<br />
Car hubs may have a brake-drum that you do not need. This can be removed using a<br />
cutting disk on a grinder. The simplest approach is to make four straight cuts around<br />
the four holes in the front, leaving a square surface to which you mount the magnet<br />
rotors. These photos show a golf rear wheel hub – first the brake-drum being cut, and<br />
then the finished hub after cutting off the drum.A typical rear wheel car hub with a <br />
flange on the back end of the stub shaft that can reused to mount it.<br />
Trailer hubs on the other hand are rather basic quality, and the bearings may be too<br />
cheap for long term use, but they are readily available items that can be purchased<br />
online as new. The drawings below (from autow.com) show a typical hub and stub<br />
axle which are bought separately.<br />
You need to be ready to replace the bearings with a named brand (such as SKF). It’s<br />
easy to replace the inner cones and rollers but the outer shells need to be knocked<br />
gently out of the hub with a suitable drift. Keep them straight by tapping evenly on<br />
opposite sides, and take care not to scratch the seating.<br />

=== Section 4, involves the craving of the blades and the welding of the base for the turbine generator. ===<br />
<br />
4.1 Making the blades <br />
The drawknife is useful for thicker chunks of wood, and for cutting down into a hollow. <br />
It can make a nice smooth job of the root of the blade, whereas the plane will work better <br />
where you need a very straight finish.<br />
<br />
'''Marking the stations.'''<br />
<br />
Place the blade with its best edge toward you on its upper surface. This will actually<br />
become the back or ‘downwind’ side of the finished blade.<br />
(Most of the front or windward side is to be cut off, so defects on this underneath side<br />
are not important.)<br />
<br />
The root of the blade will be on your right, the tip at the left, 1000 mm from the root<br />
(near the left end).<br />
<br />
Measure from the root, and mark four stations.<br />
Station A at 75mm<br />
Station B at 150 mm<br />
Station C at 500 mm<br />
The Tip at 1000 mm.<br />
<br />
<br />
At each station draw a line right around the workpiece using a square.<br />
<br />
[[File:01tur.jpeg|400px]]<br />
<br />
<br />
'''Tapering the blade'''<br />
The width of the blade tapers down from full size at station C to 55 mm wide at the<br />
tip. Mark the 55 mm tip width, measuring from the leading edge side. Draw a line<br />
though your mark to the trailing edge side at C station and cut off a triangular piece so<br />
as to achieve the correct tapered shape for the blade. Any knots in the triangular<br />
off cut do not matter as this piece is discarded. Try to make this a "square" cut,<br />
perpendicular to the back surface of the blade.<br />
You can do this with a circular saw, or by cross-cutting and shaving as described<br />
above.<br />
<br />
<br />
[[File:02tur.jpeg|400px]]<br />
<br />
'''Marking the leading and trailing edges'''<br />
The next step is to cut the windward face of the blade. This face is defined by the<br />
leading and trailing edge lines of the blade. These lines need to be marked with<br />
reference to the back face of the wood which has been uppermost in the previous<br />
operation.<br />
<br />
Turn the wood over. Start by drawing two diagonal lines between stations A and B<br />
on the front or windward side (see below). One is on the front face and the other on<br />
the trailing edge which is now toward you. <br />
<br />
[[File:03tur.jpeg|400px]]<br />
<br />
<br />
Now draw the leading edge line as shown below, <br />
from station B, down to 16mm(from the back) at station C, then continuing to the tip at<br />
7mm from the back.<br />
<br />
[[File:04tur.jpeg|400px]]<br />
<br />
<br />
(This drawing does not show the extra bit beyond the tip which may remain <br />
in your actual workpiece.)<br />
<br />
Measurements are summarised in this table below. Heights are from the back of the<br />
blade which will then rest on the bench. Remove the wood above this height. "Full"<br />
refers to the full thickness of the original piece of wood you are using.<br />
<br />
<br />
<br />
[[File:05tur.jpeg|400px]]<br />
<br />
<br />
'''The trailing''' <br />
The trailing edge line starts at the bottom of the diagonal line at station B, and <br />
rises to 5mm at C, continuing at 5 mm to the tip. This view below shows the wood <br />
already removed between the two lines to form the windward face of the blade.<br />
<br />
<br />
[[File:06tur.png|400px]]<br />
<br />
<br />
Carve this flat windward face between the 2 lines. Take care that the edges are<br />
straight, following the lines. The best tool to use for finishing the outer part of the<br />
blade is a plane, to give a smooth, straight finish. You may need to work the plane at<br />
45 degrees to the workpiece, sliding partly sideways, to form the hollow shape at<br />
station C.<br />
<br />
This step is completed when you can place a ruler across the face between the leading<br />
and trailing edge lines and there is no ‘hump’ in the middle. Fill any chips or small<br />
hollows with wood filler. If there are any serious errors, or large knots that weaken<br />
the blade then it may have to be discarded.<br />
Check the “drop” using a level as a reference. Clamp the wood so that the root part<br />
sits level, and measure the difference in level between the leading and trailing edges.<br />
The difference or “drop” should be 11 mm at the 500 mm mid-point, and 2 mm at the<br />
tip.<br />
<br />
Step 1 - Propeller: The pattern<br />
Step 2 - Propeller: drawing and cutting of the blades.<br />
Step 3 - Propeller: Sculpture of the lower surface of the blades<br />
Step 4 - Propeller: Sculpture of the lower surface of the blades<br />
Step 5 - Propeller: Blade profile finalization<br />

<br />
O principal obxectivo deste evento é prototipar un xerador eólico a pequena escala para camiñar xuntos cara á autosuficiencia neste campo.<br />
Temos o pracer de comunicarvos que do 16 ao 23 de outubro Biotranslab de Pin e The Foundry establecen unha colaboración para levar a cabo o evento Eco (i) Logic Queer Energy harvesting. O proxecto é posible grazas ao apoio de GOSH, unha rede para desenvolver e difundir proxectos baseados en hardware de código aberto para a ciencia.<br />
<br />
EcoLoxicas Queer para a captación de enerxía eolica. <br />
O evento ten como obxectivo abordar a falta de mulleres, queer, trans e diversidade nos ámbitos tecnolóxicos en xeral e do hacking máis concretamente. Pero aínda máis, pretende crear unha comunidade que avalía criticamente as narrativas hexemónicas arredor das tecnoloxías, os aspectos de modernidade dos seus supostos occidentais subliñados e as súas inflexións capitalistas inherentes, entre outros.<br />
O obxectivo principal do evento é desenvolver kits que se centren na interacción co medio natural no ámbito da enerxía.. o obxectivo principal pasa pola captación de enerxía do medio natural, a través dos aeroxeradores. Estes kits de enerxía serán escalables e poderán utilizarse tanto como material pedagóxico como para instalar centrais eléctricas específicas do sitio en diferentes sitios tamén. Este traballo ten un compoñente contrainfraestrutural: unha posible consecuencia sería capacitar ás persoas para xerar a súa propia enerxía en lugar de depender de grandes empresas e moitas veces extractivas.<br />

Here starts the documentation of the long process of the prototyping the Hugh Piggott The Piggott Turbine – Wind Empowerment model of an Open source wind turbine. We were changing a bit the goals of the event from developing small kits to going to build the real 2m size wind turbine to provide energy to the rural regional areas we were working on. In that specific event we were working at The Foundry a nice project and association that we have settled on the north part of GaliZA into the Northwest of Spain.<br />
<br />
During the event many things have been activated between the doers and the visitors; In general It was a wondering experience full of new things to study, learn, doing and understand together. <br />
<br />
We chose this model because It was full of layers of interest on the levels of learning, understanding and making it, here some levels mixed up with layers: <br />
<br />
first to all is one of the ones that is '''open source''' or at least has the option to access the full documentation.<br />
<br />
really '''rich on the pedagogical level''', we were really learning through the complete building of the generator itself, about many topics as :<br />
* electromagnetism<br />
* mathematics<br />
* geometry<br />
* electronics<br />
* AC-DC<br />
* welding<br />
* wood carving<br />
* sculpting and casting pieces<br />
and much more that was reaching through the nice process of reading, learning and building together.<br />
<br />
== Glossary ==<br />
<br />
* '''AC-'''Alternating current as produced by the alternator. All thread - USA word for 'threaded' or 'spun' rod or studding<br />
* '''Brake switch''' - A switch used to short-circuit the wires from the alternator so that it stops.<br />
* '''Catalyst''' - A chemical used to make the polyester resin set solid. Catalyst reacts with 'accelerator' already present in the resin mix. <br />
The heat of reaction sets the polyester.<br />
* '''Cavalier''' - A make of car. The cavalier in the UK is not the same as the Cavalier in the USA but both have useful wheel hubs.<br />
* '''DC - direct current''' with a positive and a negative side, as in battery circuits.<br />
* '''Diameter''' - The distance from one side of a circle to another. The width of a disk right across the middle.<br />
* '''Phase''' - The timing of the cyclical alternation of voltage in a circuit. Different phases will peak at different times.<br />
* '''Polyester''' - A type of resin used in fibreglass work. Also suitable for making castings.<br />
* '''Power''' - the rate of delivery of energy<br />
* '''Rectifier''' - A semiconductor device that turns AC into DC for charging the battery.<br />
* '''Root''' - The widest part of the blade near to the hub at the center of the rotor.<br />
* '''Rotor''' - A rotating part. Magnet rotors are the steel diskscarrying the magnets past the stator. Rotor blades are the 'propeller' <br />
driven by the wind and driving the magnet rotors.<br />
* '''Soldering''' - A method for making electrical connections between wires using a hot 'iron' and coating everything with molten solder.<br />
* '''Drag''' - A force exerted by the wind on an object. Drag is parallel to the wind direction at the object. (see Lift) <br />
* '''Stator''' - An assembly of coils embedded in a slab of resin to form part of the alternator. The magnets induce a voltage in the coils and we can use this to charge a battery.<br />
* '''Drop''' - Used here to describe a certain measurement of the shape of a windmill blade. The 'drop' affects the angle of<br />
the blade to the wind. Styrene monomer - A nasty smelling solvent in the polyester resin mix.<br />
* '''Flux''' - The 'stuff' of magnetism. Similar to 'current' in electricity. It can be visualized as 'lines' coming out of one pole and <br />
returning to the other.<br />
* '''Furling''' - A protective action that reduces exposure to violent winds by facing the blades away from them.<br />
* '''Jig''' - A device used to hold the magnets in place before setting them in resin.<br />
* '''Leading edge''' - The edge of a blade that would strike an object placed in its path as the rotor spins.<br />
* '''Lift''' - A force exerted by the wind on an object. Lift is at right angles to the wind direction at the object. (see Drag)<br />
* '''Mold''' - A shaped container in which resin castings are formed. The mould can be discarded after the casting has set.<br />
* '''Multimeter''' - A versatile electrical test instrument, used to measure voltage, current and other parameters.<br />
* '''Neodymium''' - The name given to a type of permanent magnet containing neodymium, iron and boron. These magnets are very strong and <br />
getting cheaper all the time.<br />
* '''Offset''' - An eccentric position, off centre.<br />
* '''Talcum powder'''- A cheap filler powder used to thicken the resin and slow its reaction (prevent it overheating).<br />
* '''Tail''' - A projecting vane mounted on a boom at the back ofthe windmill used to steer it into or out of the wind automatically.<br />
* '''Tap''' - a tool for making thread inside holes so you can fit a screw into the hole.<br />
* '''Thrust''' - The force of the wind pushing the machine backwards.<br />
* '''Tower''' - The mast supporting the windmill.<br />
* '''Trailing edge''' - The blade edge furthest from the leading edge. The trailing edge is sharpened, so as to release the passing <br />
air without turbulence.<br />
* '''Wedges''' - Tapered pieces of wood used to build up the blade thickness and increase its angle to the wind near the root.<br />
* '''Work-piece''' - The piece of wood or metal being shaped in the workshop.<br />
* '''Yaw bearing''' - the swivel at the top of the tower on which the windmill is mounted. The yaw bearing allows the windmill to face the wind.<br />

== The space == <br />
<br />
=== The Foundry ===<br />
The Foundry is a non-profit organization based in a previously abandoned GaliZA village. It functions both as a residency and as a project space. It subscribes to the ideals of self-organization, and has the following three objectives:<br />
1. Organizing activities in the field of the arts, science and humanities outside of traditional institutions, focusing on critical discourse.<br />
2. Promoting the exchange of ideas and intellectual collaboration outside of the constraints imposed by state and market.<br />
3. Increasing self-sufficiency, sustainability, and an awareness of the environment using appropriate technology and open source as main resources.<br />
Taking into account this context, our aim is to reinforce the capacity to generate networks flowing from rural to urban context supporting non hierarchy and democratic exchanges of knowledge and practices that can enable new and sustainable models within rural contexts. According to that we consider that the new trans-disciplinary creative sectors in which we are entangled can have a huge and positive impact in the creation of this new paradigm. https://bravosfoundry.com/<br />
Aside from that, there is thematic focus on transdisciplinarity, transfeminism and post-humanism. While this focus is not adequately grasped by identity-political categories like race or gender, we hope it leads to the subversion of hegemonic structures inscribed in the binarisms upholding many of these categories. Our interest lies in the development of tools and technologies that subvert contemporary structures of domination, exploitation and marginalization, not in those that reproduce it.<br />
We seek to develop a more sustainable environment by opening up our practices based on a free culture framework, generating networks and interest around them, enabling a flow of exchange of innovation across creative sectors focusing on revaluation of rural contexts and its knowledge heritage.<br />

=== '''Section 2, involves the construction of '''the alternator''' parts using the devices from the section 1.''' ===<br />
<br />
'''Alternator'''<br />
Each magnet rotor is a steel disk with 12 magnets placed on it and set in resin. The magnets are each 50 x 50 x 20 mm, and they only just fit on the disk. The idea is to achieve the maximum amount of flux in a given space.<br />
The turbine runs at 650 rpm for 400W output, so the centrifugal force on the magnets is 60 times the force of gravity. To prevent them flying off, the resin casting needs to be reinforced. Stainless steel wire rope is placed around the outside of the magnets to hold the casting together at high rpm. We use stainless because it is non-magnetic, or at least less magnetic than normal steel wire rope. <br />
<br />
You will wind the coils that produce the output power and cast them in resin to form a stator between the two magnet rotors. Photos of the final pieces here <br />

Step - Generator, rotor: Preparation of the metallic disk. was made by machine at the shop <br />
<br />
[[File:prod05.jpg|300px]] <br />
<br />
Step - Generator, rotor: Preparation of the wheel hub.<br />
<br />
[[File:frame10.jpg|300px]]<br />
<br />
'''The wheel hub'''<br />
<br />
You can find a used car rear wheel hub (Golf, Toyota, etc.) that has a simple way to<br />
attach the axle, or alternatively buy a trailer hubs online new at low cost.<br />
PCD or ‘pitch circle diameter' is the diameter of the circle of the hole pattern in the<br />
hub, and usually this will be 100mm for a car wheel hub, or 4 inches for a trailer hub.<br />
Car hubs may have a brake-drum that you do not need. This can be removed using a<br />
cutting disk on a grinder. The simplest approach is to make four straight cuts around<br />
the four holes in the front, leaving a square surface to which you mount the magnet<br />
rotors. These photos show a golf rear wheel hub – first the brake-drum being cut, and<br />
then the finished hub after cutting off the drum.A typical rear wheel car hub with a <br />
flange on the back end of the stub shaft that can reused to mount it.<br />
Trailer hubs on the other hand are rather basic quality, and the bearings may be too<br />
cheap for long term use, but they are readily available items that can be purchased<br />
online as new. The drawings below (from autow.com) show a typical hub and stub<br />
axle which are bought separately.<br />
You need to be ready to replace the bearings with a named brand (such as SKF). It’s<br />
easy to replace the inner cones and rollers but the outer shells need to be knocked<br />
gently out of the hub with a suitable drift. Keep them straight by tapping evenly on<br />
opposite sides, and take care not to scratch the seating.<br />

=== Section 4, involves the craving of the blades and the welding of the base for the turbine generator. ===<br />
<br />
4.1 Making the blades <br />
The drawknife is useful for thicker chunks of wood, and for cutting down into a hollow. <br />
It can make a nice smooth job of the root of the blade, whereas the plane will work better <br />
where you need a very straight finish.<br />
<br />
'''Marking the stations.'''<br />
<br />
Place the blade with its best edge toward you on its upper surface. This will actually<br />
become the back or ‘downwind’ side of the finished blade.<br />
(Most of the front or windward side is to be cut off, so defects on this underneath side<br />
are not important.)<br />
<br />
The root of the blade will be on your right, the tip at the left, 1000 mm from the root<br />
(near the left end).<br />
<br />
Measure from the root, and mark four stations.<br />
Station A at 75mm<br />
Station B at 150 mm<br />
Station C at 500 mm<br />
The Tip at 1000 mm.<br />
<br />
<br />
At each station draw a line right around the workpiece using a square.<br />
<br />
[[File:01tur.jpeg|400px]]<br />
<br />
<br />
'''Tapering the blade'''<br />
The width of the blade tapers down from full size at station C to 55 mm wide at the<br />
tip. Mark the 55 mm tip width, measuring from the leading edge side. Draw a line<br />
though your mark to the trailing edge side at C station and cut off a triangular piece so<br />
as to achieve the correct tapered shape for the blade. Any knots in the triangular<br />
off cut do not matter as this piece is discarded. Try to make this a "square" cut,<br />
perpendicular to the back surface of the blade.<br />
You can do this with a circular saw, or by cross-cutting and shaving as described<br />
above.<br />
<br />
<br />
[[File:02tur.jpeg|400px]]<br />
<br />
'''Marking the leading and trailing edges'''<br />
The next step is to cut the windward face of the blade. This face is defined by the<br />
leading and trailing edge lines of the blade. These lines need to be marked with<br />
reference to the back face of the wood which has been uppermost in the previous<br />
operation.<br />
<br />
Turn the wood over. Start by drawing two diagonal lines between stations A and B<br />
on the front or windward side (see below). One is on the front face and the other on<br />
the trailing edge which is now toward you. <br />
<br />
[[File:03tur.jpeg|400px]]<br />
<br />
<br />
Now draw the leading edge line as shown below, <br />
from station B, down to 16mm(from the back) at station C, then continuing to the tip at<br />
7mm from the back.<br />
<br />
[[File:04tur.jpeg|400px]]<br />
<br />
<br />
(This drawing does not show the extra bit beyond the tip which may remain <br />
in your actual workpiece.)<br />
<br />
Measurements are summarised in this table below. Heights are from the back of the<br />
blade which will then rest on the bench. Remove the wood above this height. "Full"<br />
refers to the full thickness of the original piece of wood you are using.<br />
<br />
<br />
<br />
[[File:05tur.jpeg|400px]]<br />
<br />
<br />
'''The trailing''' <br />
The trailing edge line starts at the bottom of the diagonal line at station B, and <br />
rises to 5mm at C, continuing at 5 mm to the tip. This view below shows the wood <br />
already removed between the two lines to form the windward face of the blade.<br />
<br />
<br />
[[File:06tur.png|400px]]<br />
<br />
<br />
Carve this flat windward face between the 2 lines. Take care that the edges are<br />
straight, following the lines. The best tool to use for finishing the outer part of the<br />
blade is a plane, to give a smooth, straight finish. You may need to work the plane at<br />
45 degrees to the workpiece, sliding partly sideways, to form the hollow shape at<br />
station C.<br />
<br />
This step is completed when you can place a ruler across the face between the leading<br />
and trailing edge lines and there is no ‘hump’ in the middle. Fill any chips or small<br />
hollows with wood filler. If there are any serious errors, or large knots that weaken<br />
the blade then it may have to be discarded.<br />
Check the “drop” using a level as a reference. Clamp the wood so that the root part<br />
sits level, and measure the difference in level between the leading and trailing edges.<br />
The difference or “drop” should be 11 mm at the 500 mm mid-point, and 2 mm at the<br />
tip.<br />
<br />

Step 2 - Propeller: drawing and cutting of the blades.<br />

O principal obxectivo deste evento é prototipar un xerador eólico a pequena escala para camiñar xuntos cara á autosuficiencia neste campo.<br />
Temos o pracer de comunicarvos que do 16 ao 23 de outubro Biotranslab de Pin e The Foundry establecen unha colaboración para levar a cabo o evento Eco (i) Logic Queer Energy harvesting. O proxecto é posible grazas ao apoio de GOSH, unha rede para desenvolver e difundir proxectos baseados en hardware de código aberto para a ciencia.<br />
<br />
EcoLoxicas Queer para a captación de enerxía eolica. <br />
O evento ten como obxectivo abordar a falta de mulleres, queer, trans e diversidade nos ámbitos tecnolóxicos en xeral e do hacking máis concretamente. Pero aínda máis, pretende crear unha comunidade que avalía criticamente as narrativas hexemónicas arredor das tecnoloxías, os aspectos de modernidade dos seus supostos occidentais subliñados e as súas inflexións capitalistas inherentes, entre outros.<br />
O obxectivo principal do evento é desenvolver kits que se centren na interacción co medio natural no ámbito da enerxía.. o obxectivo principal pasa pola captación de enerxía do medio natural, a través dos aeroxeradores. Estes kits de enerxía serán escalables e poderán utilizarse tanto como material pedagóxico como para instalar centrais eléctricas específicas do sitio en diferentes sitios tamén. Este traballo ten un compoñente contrainfraestrutural: unha posible consecuencia sería capacitar ás persoas para xerar a súa propia enerxía en lugar de depender de grandes empresas e moitas veces extractivas.<br />

''Pedagogies of the Wind and Stars. The social relations that we (were never meant to) survive, also live in our bodies painfully, and Audre Lorde is not here to remind us of this lesson herself, except in as much that she is present in the pedagogical wind. But wind is our teacher (74). -Alexis Pauline Gumbs'' from the book Mapping Queer Space(s) of Praxis and Pedagogy <br />

<br />
We have the pleasure to communicate you that from 16 to 29 of October Pin Biotranslab, Casa do Río e The Foundry establishes a collaboration to run the event Eco (i) Logic Queer Energy harvesting. The project is possible thanks to the support of GOSH, an network for develop and disseminate projects based on Open Source hardware for Science.<br />
<br />
'''Eco (i) Logic Queer Energy harvesting''' <br />
The event aims at addressing the lack of women, queer, trans and diversity in technological fields in general and hacking more specifically. But even more so, it aims at creating a community that critically assesses the hegemonic narratives around technologies, the modernity aspects of its underlining Western assumptions and its inherent capitalist inflections, among others.<br />
The main purpose of the event is to develop kits that focus on interacting with the natural environment on the field of energy.. the main objective lies on harvesting energy of the natural environment, through wind turbines. These power kits will be scalable and can be used both as pedagogical material and to set up site-specific power plants in different sites as well. There is a counter-infrastructural component to this work: one possible consequence would be to empower people to generate their own energy instead of relying on large and often extractive companies.<br />

<br />
* '''AC-'''Alternating current as produced by the alternator. All thread - USA word for 'threaded' or 'spun' rod or studding<br />
* '''Brake switch''' - A switch used to short-circuit the wires from the alternator so that it stops.<br />
* '''Catalyst''' - A chemical used to make the polyester resin set solid. Catalyst reacts with 'accelerator' already present in the resin mix. <br />
The heat of reaction sets the polyester.<br />
* '''Cavalier''' - A make of car. The cavalier in the UK is not the same as the Cavalier in the USA but both have useful wheel hubs.<br />
* '''DC - direct current''' with a positive and a negative side, as in battery circuits.<br />
* '''Diameter''' - The distance from one side of a circle to another. The width of a disk right across the middle.<br />
* '''Phase''' - The timing of the cyclical alternation of voltage in a circuit. Different phases will peak at different times.<br />
* '''Polyester''' - A type of resin used in fibreglass work. Also suitable for making castings.<br />
* '''Power''' - the rate of delivery of energy<br />
* '''Rectifier''' - A semiconductor device that turns AC into DC for charging the battery.<br />
* '''Root''' - The widest part of the blade near to the hub at the center of the rotor.<br />
* '''Rotor''' - A rotating part. Magnet rotors are the steel diskscarrying the magnets past the stator. Rotor blades are the 'propeller' <br />
driven by the wind and driving the magnet rotors.<br />
* '''Soldering''' - A method for making electrical connections between wires using a hot 'iron' and coating everything with molten solder.<br />
* '''Drag''' - A force exerted by the wind on an object. Drag is parallel to the wind direction at the object. (see Lift) <br />
* '''Stator''' - An assembly of coils embedded in a slab of resin to form part of the alternator. The magnets induce a voltage in the coils and we can use this to charge a battery.<br />
* '''Drop''' - Used here to describe a certain measurement of the shape of a windmill blade. The 'drop' affects the angle of<br />
the blade to the wind. Styrene monomer - A nasty smelling solvent in the polyester resin mix.<br />
* '''Flux''' - The 'stuff' of magnetism. Similar to 'current' in electricity. It can be visualized as 'lines' coming out of one pole and <br />
returning to the other.<br />
* '''Furling''' - A protective action that reduces exposure to violent winds by facing the blades away from them.<br />
* '''Jig''' - A device used to hold the magnets in place before setting them in resin.<br />
* '''Leading edge''' - The edge of a blade that would strike an object placed in its path as the rotor spins.<br />
* '''Lift''' - A force exerted by the wind on an object. Lift is at right angles to the wind direction at the object. (see Drag)<br />

* '''Tail''' - A projecting vane mounted on a boom at the back ofthe windmill used to steer it into or out of the wind automatically.<br />
* '''Tap''' - a tool for making thread inside holes so you can fit a screw into the hole.<br />
* '''Thrust''' - The force of the wind pushing the machine backwards.<br />
* '''Tower''' - The mast supporting the windmill.<br />
* '''Trailing edge''' - The blade edge furthest from the leading edge. The trailing edge is sharpened, so as to release the passing <br />
air without turbulence.<br />
* '''Wedges''' - Tapered pieces of wood used to build up the blade thickness and increase its angle to the wind near the root.<br />
* '''Work-piece''' - The piece of wood or metal being shaped in the workshop.<br />
* '''Yaw bearing''' - the swivel at the top of the tower on which the windmill is mounted. The yaw bearing allows the windmill to face the wind.<br />

=== The Foundry ===<br />
The Foundry is a non-profit organization based in a previously abandoned GaliZA village. It functions both as a residency and as a project space. It subscribes to the ideals of self-organization, and has the following three objectives:<br />
1. Organizing activities in the field of the arts, science and humanities outside of traditional institutions, focusing on critical discourse.<br />
2. Promoting the exchange of ideas and intellectual collaboration outside of the constraints imposed by state and market.<br />
3. Increasing self-sufficiency, sustainability, and an awareness of the environment using appropriate technology and open source as main resources.<br />
Taking into account this context, our aim is to reinforce the capacity to generate networks flowing from rural to urban context supporting non hierarchy and democratic exchanges of knowledge and practices that can enable new and sustainable models within rural contexts. According to that we consider that the new trans-disciplinary creative sectors in which we are entangled can have a huge and positive impact in the creation of this new paradigm. https://bravosfoundry.com/<br />
Aside from that, there is thematic focus on transdisciplinarity, transfeminism and post-humanism. While this focus is not adequately grasped by identity-political categories like race or gender, we hope it leads to the subversion of hegemonic structures inscribed in the binarisms upholding many of these categories. Our interest lies in the development of tools and technologies that subvert contemporary structures of domination, exploitation and marginalization, not in those that reproduce it.<br />
We seek to develop a more sustainable environment by opening up our practices based on a free culture framework, generating networks and interest around them, enabling a flow of exchange of innovation across creative sectors focusing on revaluation of rural contexts and its knowledge heritage.<br />

=== '''Section 2, involves the construction of '''the alternator''' parts using the devices from the section 1.''' ===<br />
<br />
'''Alternator'''<br />
Each magnet rotor is a steel disk with 12 magnets placed on it and set in resin. The magnets are each 50 x 50 x 20 mm, and they only just fit on the disk. The idea is to achieve the maximum amount of flux in a given space.<br />
The turbine runs at 650 rpm for 400W output, so the centrifugal force on the magnets is 60 times the force of gravity. To prevent them flying off, the resin casting needs to be reinforced. Stainless steel wire rope is placed around the outside of the magnets to hold the casting together at high rpm. We use stainless because it is non-magnetic, or at least less magnetic than normal steel wire rope. <br />
<br />
You will wind the coils that produce the output power and cast them in resin to form a stator between the two magnet rotors. Photos of the final pieces here <br />

<br />
[[File:prod05.jpg|300px]] <br />
<br />
Step - Generator, rotor: Preparation of the wheel hub.<br />
<br />
[[File:frame10.jpg|300px]]<br />
<br />
'''The wheel hub'''<br />
<br />
You can find a used car rear wheel hub (Golf, Toyota, etc.) that has a simple way to<br />
attach the axle, or alternatively buy a trailer hubs online new at low cost.<br />
PCD or ‘pitch circle diameter' is the diameter of the circle of the hole pattern in the<br />
hub, and usually this will be 100mm for a car wheel hub, or 4 inches for a trailer hub.<br />
Car hubs may have a brake-drum that you do not need. This can be removed using a<br />
cutting disk on a grinder. The simplest approach is to make four straight cuts around<br />
the four holes in the front, leaving a square surface to which you mount the magnet<br />
rotors. These photos show a golf rear wheel hub – first the brake-drum being cut, and<br />
then the finished hub after cutting off the drum.A typical rear wheel car hub with a <br />
flange on the back end of the stub shaft that can reused to mount it.<br />
Trailer hubs on the other hand are rather basic quality, and the bearings may be too<br />
cheap for long term use, but they are readily available items that can be purchased<br />
online as new. The drawings below (from autow.com) show a typical hub and stub<br />
axle which are bought separately.<br />
You need to be ready to replace the bearings with a named brand (such as SKF). It’s<br />
easy to replace the inner cones and rollers but the outer shells need to be knocked<br />
gently out of the hub with a suitable drift. Keep them straight by tapping evenly on<br />
opposite sides, and take care not to scratch the seating.<br />

=== Section 4, involves the craving of the blades and the welding of the base for the turbine generator. ===<br />
<br />
4.1 Making the blades <br />
The drawknife is useful for thicker chunks of wood, and for cutting down into a hollow. <br />
It can make a nice smooth job of the root of the blade, whereas the plane will work better <br />
where you need a very straight finish.<br />
<br />
'''Marking the stations.'''<br />
<br />
Place the blade with its best edge toward you on its upper surface. This will actually<br />
become the back or ‘downwind’ side of the finished blade.<br />
(Most of the front or windward side is to be cut off, so defects on this underneath side<br />
are not important.)<br />
<br />
The root of the blade will be on your right, the tip at the left, 1000 mm from the root<br />
(near the left end).<br />
<br />
Measure from the root, and mark four stations.<br />
Station A at 75mm<br />
Station B at 150 mm<br />
Station C at 500 mm<br />
The Tip at 1000 mm.<br />
<br />
<br />
At each station draw a line right around the workpiece using a square.<br />
<br />
[[File:01tur.jpeg|400px]]<br />
<br />
<br />
'''Tapering the blade'''<br />
The width of the blade tapers down from full size at station C to 55 mm wide at the<br />
tip. Mark the 55 mm tip width, measuring from the leading edge side. Draw a line<br />
though your mark to the trailing edge side at C station and cut off a triangular piece so<br />
as to achieve the correct tapered shape for the blade. Any knots in the triangular<br />
off cut do not matter as this piece is discarded. Try to make this a "square" cut,<br />
perpendicular to the back surface of the blade.<br />
You can do this with a circular saw, or by cross-cutting and shaving as described<br />
above.<br />
<br />
<br />
[[File:02tur.jpeg|400px]]<br />
<br />
'''Marking the leading and trailing edges'''<br />
The next step is to cut the windward face of the blade. This face is defined by the<br />
leading and trailing edge lines of the blade. These lines need to be marked with<br />
reference to the back face of the wood which has been uppermost in the previous<br />
operation.<br />
<br />
Turn the wood over. Start by drawing two diagonal lines between stations A and B<br />
on the front or windward side (see below). One is on the front face and the other on<br />
the trailing edge which is now toward you. <br />
<br />
[[File:03tur.jpeg|400px]]<br />
<br />
<br />
Now draw the leading edge line as shown below, <br />
from station B, down to 16mm(from the back) at station C, then continuing to the tip at<br />
7mm from the back.<br />
<br />
[[File:04tur.jpeg|400px]]<br />
<br />
<br />
(This drawing does not show the extra bit beyond the tip which may remain <br />
in your actual workpiece.)<br />
<br />
Measurements are summarised in this table below. Heights are from the back of the<br />
blade which will then rest on the bench. Remove the wood above this height. "Full"<br />
refers to the full thickness of the original piece of wood you are using.<br />
<br />
<br />
<br />
[[File:05tur.jpeg|400px]]<br />
<br />
<br />
'''The trailing''' <br />
The trailing edge line starts at the bottom of the diagonal line at station B, and <br />
rises to 5mm at C, continuing at 5 mm to the tip. This view below shows the wood <br />
already removed between the two lines to form the windward face of the blade.<br />
<br />
<br />
[[File:06tur.png|400px]]<br />
<br />
<br />
Carve this flat windward face between the 2 lines. Take care that the edges are<br />
straight, following the lines. The best tool to use for finishing the outer part of the<br />
blade is a plane, to give a smooth, straight finish. You may need to work the plane at<br />
45 degrees to the workpiece, sliding partly sideways, to form the hollow shape at<br />
station C.<br />
<br />
This step is completed when you can place a ruler across the face between the leading<br />
and trailing edge lines and there is no ‘hump’ in the middle. Fill any chips or small<br />
hollows with wood filler. If there are any serious errors, or large knots that weaken<br />
the blade then it may have to be discarded.<br />
Check the “drop” using a level as a reference. Clamp the wood so that the root part<br />
sits level, and measure the difference in level between the leading and trailing edges.<br />
The difference or “drop” should be 11 mm at the 500 mm mid-point, and 2 mm at the<br />
tip.<br />

O principal obxectivo deste evento é prototipar un xerador eólico a pequena escala para camiñar xuntos cara á autosuficiencia neste campo.<br />
Temos o pracer de comunicarvos que do 16 ao 23 de outubro Biotranslab de Pin e The Foundry establecen unha colaboración para levar a cabo o evento Eco (i) Logic Queer Energy harvesting. O proxecto é posible grazas ao apoio de GOSH, unha rede para desenvolver e difundir proxectos baseados en hardware de código aberto para a ciencia.<br />
<br />
EcoLoxicas Queer para a captación de enerxía eolica. <br />
O evento ten como obxectivo abordar a falta de mulleres, queer, trans e diversidade nos ámbitos tecnolóxicos en xeral e do hacking máis concretamente. Pero aínda máis, pretende crear unha comunidade que avalía criticamente as narrativas hexemónicas arredor das tecnoloxías, os aspectos de modernidade dos seus supostos occidentais subliñados e as súas inflexións capitalistas inherentes, entre outros.<br />
O obxectivo principal do evento é desenvolver kits que se centren na interacción co medio natural no ámbito da enerxía.. o obxectivo principal pasa pola captación de enerxía do medio natural, a través dos aeroxeradores. Estes kits de enerxía serán escalables e poderán utilizarse tanto como material pedagóxico como para instalar centrais eléctricas específicas do sitio en diferentes sitios tamén. Este traballo ten un compoñente contrainfraestrutural: unha posible consecuencia sería capacitar ás persoas para xerar a súa propia enerxía en lugar de depender de grandes empresas e moitas veces extractivas.<br />

''Pedagogies of the Wind and Stars. The social relations that we (were never meant to) survive, also live in our bodies painfully, and Audre Lorde is not here to remind us of this lesson herself, except in as much that she is present in the pedagogical wind. But wind is our teacher (74). -Alexis Pauline Gumbs'' from the book Mapping Queer Space(s) of Praxis and Pedagogy <br />
Editors: Elizabeth McNeil, James E. Wermers, Joshua O. Lunn'' <br />
<br />
We have the pleasure to communicate you that from 16 to 29 of October Pin Biotranslab, Casa do Río e The Foundry establishes a collaboration to run the event Eco (i) Logic Queer Energy harvesting. The project is possible thanks to the support of GOSH, an network for develop and disseminate projects based on Open Source hardware for Science.<br />
<br />
'''Eco (i) Logic Queer Energy harvesting''' <br />
The event aims at addressing the lack of women, queer, trans and diversity in technological fields in general and hacking more specifically. But even more so, it aims at creating a community that critically assesses the hegemonic narratives around technologies, the modernity aspects of its underlining Western assumptions and its inherent capitalist inflections, among others.<br />
The main purpose of the event is to develop kits that focus on interacting with the natural environment on the field of energy.. the main objective lies on harvesting energy of the natural environment, through wind turbines. These power kits will be scalable and can be used both as pedagogical material and to set up site-specific power plants in different sites as well. There is a counter-infrastructural component to this work: one possible consequence would be to empower people to generate their own energy instead of relying on large and often extractive companies.<br />
<br />
== Introduction and values of the process ==<br />
<br />
Here starts the documentation of the long process of the prototyping the Hugh Piggott The Piggott Turbine – Wind Empowerment model of an Open source wind turbine. We were changing a bit the goals of the event from developing small kits to going to build the real 2m size wind turbine to provide energy to the rural regional areas we were working on. In that specific event we were working at The Foundry a nice project and association that we have settled on the north part of GaliZA into the Northwest of Spain.<br />
<br />
During the event many things have been activated between the doers and the visitors; In general It was a wondering experience full of new things to study, learn, doing and understand together. <br />
<br />
We chose this model because It was full of layers of interest on the levels of learning, understanding and making it, here some levels mixed up with layers: <br />
<br />
first to all is one of the ones that is '''open source''' or at least has the option to access the full documentation.<br />
<br />
really '''rich on the pedagogical level''', we were really learning through the complete building of the generator itself, about many topics as :<br />
* electromagnetism<br />
* mathematics<br />
* geometry<br />
* electronics<br />
* AC-DC<br />
* welding<br />
* wood carving<br />
* sculpting and casting pieces<br />
and much more that was reaching through the nice process of reading, learning and building together.<br />

* '''Cavalier''' - A make of car. The cavalier in the UK is not the same as the Cavalier in the USA but both have useful wheel hubs.<br />
* '''DC - direct current''' with a positive and a negative side, as in battery circuits.<br />
* '''Diameter''' - The distance from one side of a circle to another. The width of a disk right across the middle.<br />
* '''Phase''' - The timing of the cyclical alternation of voltage in a circuit. Different phases will peak at different times.<br />
* '''Polyester''' - A type of resin used in fibreglass work. Also suitable for making castings.<br />
* '''Power''' - the rate of delivery of energy<br />
* '''Rectifier''' - A semiconductor device that turns AC into DC for charging the battery.<br />
* '''Root''' - The widest part of the blade near to the hub at the center of the rotor.<br />
* '''Rotor''' - A rotating part. Magnet rotors are the steel diskscarrying the magnets past the stator. Rotor blades are the 'propeller' <br />
driven by the wind and driving the magnet rotors.<br />
* '''Soldering''' - A method for making electrical connections between wires using a hot 'iron' and coating everything with molten solder.<br />
* '''Drag''' - A force exerted by the wind on an object. Drag is parallel to the wind direction at the object. (see Lift) <br />
* '''Stator''' - An assembly of coils embedded in a slab of resin to form part of the alternator. The magnets induce a voltage in the coils and we can use this to charge a battery.<br />
* '''Drop''' - Used here to describe a certain measurement of the shape of a windmill blade. The 'drop' affects the angle of<br />
the blade to the wind. Styrene monomer - A nasty smelling solvent in the polyester resin mix.<br />
* '''Flux''' - The 'stuff' of magnetism. Similar to 'current' in electricity. It can be visualized as 'lines' coming out of one pole and <br />
returning to the other.<br />
* '''Furling''' - A protective action that reduces exposure to violent winds by facing the blades away from them.<br />
* '''Jig''' - A device used to hold the magnets in place before setting them in resin.<br />
* '''Leading edge''' - The edge of a blade that would strike an object placed in its path as the rotor spins.<br />

* '''Thrust''' - The force of the wind pushing the machine backwards.<br />
* '''Tower''' - The mast supporting the windmill.<br />
* '''Trailing edge''' - The blade edge furthest from the leading edge. The trailing edge is sharpened, so as to release the passing <br />
air without turbulence.<br />
* '''Wedges''' - Tapered pieces of wood used to build up the blade thickness and increase its angle to the wind near the root.<br />
* '''Work-piece''' - The piece of wood or metal being shaped in the workshop.<br />
* '''Yaw bearing''' - the swivel at the top of the tower on which the windmill is mounted. The yaw bearing allows the windmill to face the wind.<br />

=== The Foundry ===<br />
The Foundry is a non-profit organization based in a previously abandoned GaliZA village. It functions both as a residency and as a project space. It subscribes to the ideals of self-organization, and has the following three objectives:<br />
1. Organizing activities in the field of the arts, science and humanities outside of traditional institutions, focusing on critical discourse.<br />
2. Promoting the exchange of ideas and intellectual collaboration outside of the constraints imposed by state and market.<br />
3. Increasing self-sufficiency, sustainability, and an awareness of the environment using appropriate technology and open source as main resources.<br />
Taking into account this context, our aim is to reinforce the capacity to generate networks flowing from rural to urban context supporting non hierarchy and democratic exchanges of knowledge and practices that can enable new and sustainable models within rural contexts. According to that we consider that the new trans-disciplinary creative sectors in which we are entangled can have a huge and positive impact in the creation of this new paradigm. https://bravosfoundry.com/<br />
Aside from that, there is thematic focus on transdisciplinarity, transfeminism and post-humanism. While this focus is not adequately grasped by identity-political categories like race or gender, we hope it leads to the subversion of hegemonic structures inscribed in the binarisms upholding many of these categories. Our interest lies in the development of tools and technologies that subvert contemporary structures of domination, exploitation and marginalization, not in those that reproduce it.<br />
We seek to develop a more sustainable environment by opening up our practices based on a free culture framework, generating networks and interest around them, enabling a flow of exchange of innovation across creative sectors focusing on revaluation of rural contexts and its knowledge heritage.<br />

=== '''Section 2, involves the construction of '''the alternator''' parts using the devices from the section 1.''' ===<br />
<br />
'''Alternator'''<br />
Each magnet rotor is a steel disk with 12 magnets placed on it and set in resin. The magnets are each 50 x 50 x 20 mm, and they only just fit on the disk. The idea is to achieve the maximum amount of flux in a given space.<br />
The turbine runs at 650 rpm for 400W output, so the centrifugal force on the magnets is 60 times the force of gravity. To prevent them flying off, the resin casting needs to be reinforced. Stainless steel wire rope is placed around the outside of the magnets to hold the casting together at high rpm. We use stainless because it is non-magnetic, or at least less magnetic than normal steel wire rope. <br />
<br />
You will wind the coils that produce the output power and cast them in resin to form a stator between the two magnet rotors. Photos of the final pieces here <br />

<br />
[[File:prod05.jpg|300px]] <br />
<br />
Step - Generator, rotor: Preparation of the wheel hub.<br />
<br />
[[File:frame10.jpg|300px]]<br />
<br />
'''The wheel hub'''<br />
<br />
You can find a used car rear wheel hub (Golf, Toyota, etc.) that has a simple way to<br />
attach the axle, or alternatively buy a trailer hubs online new at low cost.<br />
PCD or ‘pitch circle diameter' is the diameter of the circle of the hole pattern in the<br />
hub, and usually this will be 100mm for a car wheel hub, or 4 inches for a trailer hub.<br />
Car hubs may have a brake-drum that you do not need. This can be removed using a<br />
cutting disk on a grinder. The simplest approach is to make four straight cuts around<br />
the four holes in the front, leaving a square surface to which you mount the magnet<br />
rotors. These photos show a golf rear wheel hub – first the brake-drum being cut, and<br />
then the finished hub after cutting off the drum.A typical rear wheel car hub with a <br />
flange on the back end of the stub shaft that can reused to mount it.<br />
Trailer hubs on the other hand are rather basic quality, and the bearings may be too<br />
cheap for long term use, but they are readily available items that can be purchased<br />
online as new. The drawings below (from autow.com) show a typical hub and stub<br />
axle which are bought separately.<br />
You need to be ready to replace the bearings with a named brand (such as SKF). It’s<br />
easy to replace the inner cones and rollers but the outer shells need to be knocked<br />
gently out of the hub with a suitable drift. Keep them straight by tapping evenly on<br />
opposite sides, and take care not to scratch the seating.<br />

=== Section 4, involves the craving of the blades and the welding of the base for the turbine generator. ===<br />
<br />
4.1 Making the blades <br />
The drawknife is useful for thicker chunks of wood, and for cutting down into a hollow. <br />
It can make a nice smooth job of the root of the blade, whereas the plane will work better <br />
where you need a very straight finish.<br />
<br />
'''Marking the stations.'''<br />
<br />
Place the blade with its best edge toward you on its upper surface. This will actually<br />
become the back or ‘downwind’ side of the finished blade.<br />
(Most of the front or windward side is to be cut off, so defects on this underneath side<br />
are not important.)<br />
<br />
The root of the blade will be on your right, the tip at the left, 1000 mm from the root<br />
(near the left end).<br />
<br />
Measure from the root, and mark four stations.<br />
Station A at 75mm<br />
Station B at 150 mm<br />
Station C at 500 mm<br />
The Tip at 1000 mm.<br />
<br />
<br />
At each station draw a line right around the workpiece using a square.<br />
<br />
[[File:01tur.jpeg|400px]]<br />
<br />
<br />
'''Tapering the blade'''<br />
The width of the blade tapers down from full size at station C to 55 mm wide at the<br />
tip. Mark the 55 mm tip width, measuring from the leading edge side. Draw a line<br />
though your mark to the trailing edge side at C station and cut off a triangular piece so<br />
as to achieve the correct tapered shape for the blade. Any knots in the triangular<br />
off cut do not matter as this piece is discarded. Try to make this a "square" cut,<br />
perpendicular to the back surface of the blade.<br />
You can do this with a circular saw, or by cross-cutting and shaving as described<br />
above.<br />
<br />
<br />
[[File:02tur.jpeg|400px]]<br />
<br />
'''Marking the leading and trailing edges'''<br />
The next step is to cut the windward face of the blade. This face is defined by the<br />
leading and trailing edge lines of the blade. These lines need to be marked with<br />
reference to the back face of the wood which has been uppermost in the previous<br />
operation.<br />
<br />
Turn the wood over. Start by drawing two diagonal lines between stations A and B<br />
on the front or windward side (see below). One is on the front face and the other on<br />
the trailing edge which is now toward you. <br />
<br />
[[File:03tur.jpeg|400px]]<br />
<br />
<br />
Now draw the leading edge line as shown below, <br />
from station B, down to 16mm(from the back) at station C, then continuing to the tip at<br />
7mm from the back.<br />
<br />
[[File:04tur.jpeg|400px]]<br />
<br />
<br />
(This drawing does not show the extra bit beyond the tip which may remain <br />
in your actual workpiece.)<br />
<br />
Measurements are summarised in this table below. Heights are from the back of the<br />
blade which will then rest on the bench. Remove the wood above this height. "Full"<br />
refers to the full thickness of the original piece of wood you are using.<br />
<br />
<br />
<br />
[[File:05tur.jpeg|400px]]<br />
<br />
<br />
'''The trailing''' <br />
The trailing edge line starts at the bottom of the diagonal line at station B, and <br />
rises to 5mm at C, continuing at 5 mm to the tip. This view below shows the wood <br />
already removed between the two lines to form the windward face of the blade.<br />
<br />
<br />
[[File:06tur.png|400px]]<br />
<br />
<br />
Carve this flat windward face between the 2 lines. Take care that the edges are<br />
straight, following the lines. The best tool to use for finishing the outer part of the<br />
blade is a plane, to give a smooth, straight finish. You may need to work the plane at<br />
45 degrees to the workpiece, sliding partly sideways, to form the hollow shape at<br />
station C.<br />
<br />
This step is completed when you can place a ruler across the face between the leading<br />
and trailing edge lines and there is no ‘hump’ in the middle. Fill any chips or small<br />
hollows with wood filler. If there are any serious errors, or large knots that weaken<br />
the blade then it may have to be discarded.<br />
Check the “drop” using a level as a reference. Clamp the wood so that the root part<br />
sits level, and measure the difference in level between the leading and trailing edges.<br />
The difference or “drop” should be 11 mm at the 500 mm mid-point, and 2 mm at the<br />
tip.<br />
<br />

Step 2 - Propeller: drawing and cutting of the blades.<br />

O principal obxectivo deste evento é prototipar un xerador eólico a pequena escala para camiñar xuntos cara á autosuficiencia neste campo.<br />
Temos o pracer de comunicarvos que do 16 ao 23 de outubro Biotranslab de Pin e The Foundry establecen unha colaboración para levar a cabo o evento Eco (i) Logic Queer Energy harvesting. O proxecto é posible grazas ao apoio de GOSH, unha rede para desenvolver e difundir proxectos baseados en hardware de código aberto para a ciencia.<br />
<br />
EcoLoxicas Queer para a captación de enerxía eolica. <br />
O evento ten como obxectivo abordar a falta de mulleres, queer, trans e diversidade nos ámbitos tecnolóxicos en xeral e do hacking máis concretamente. Pero aínda máis, pretende crear unha comunidade que avalía criticamente as narrativas hexemónicas arredor das tecnoloxías, os aspectos de modernidade dos seus supostos occidentais subliñados e as súas inflexións capitalistas inherentes, entre outros.<br />
O obxectivo principal do evento é desenvolver kits que se centren na interacción co medio natural no ámbito da enerxía.. o obxectivo principal pasa pola captación de enerxía do medio natural, a través dos aeroxeradores. Estes kits de enerxía serán escalables e poderán utilizarse tanto como material pedagóxico como para instalar centrais eléctricas específicas do sitio en diferentes sitios tamén. Este traballo ten un compoñente contrainfraestrutural: unha posible consecuencia sería capacitar ás persoas para xerar a súa propia enerxía en lugar de depender de grandes empresas e moitas veces extractivas.<br />

''Pedagogies of the Wind and Stars. The social relations that we (were never meant to) survive, also live in our bodies painfully, and Audre Lorde is not here to remind us of this lesson herself, except in as much that she is present in the pedagogical wind. But wind is our teacher (74). -Alexis Pauline Gumbs'' from the book Mapping Queer Space(s) of Praxis and Pedagogy <br />
Editors: Elizabeth McNeil, James E. Wermers, Joshua O. Lunn'' <br />
<br />
We have the pleasure to communicate you that from 16 to 29 of October Pin Biotranslab, Casa do Río e The Foundry establishes a collaboration to run the event Eco (i) Logic Queer Energy harvesting. The project is possible thanks to the support of GOSH, an network for develop and disseminate projects based on Open Source hardware for Science.<br />
<br />
'''Eco (i) Logic Queer Energy harvesting''' <br />
The event aims at addressing the lack of women, queer, trans and diversity in technological fields in general and hacking more specifically. But even more so, it aims at creating a community that critically assesses the hegemonic narratives around technologies, the modernity aspects of its underlining Western assumptions and its inherent capitalist inflections, among others.<br />
The main purpose of the event is to develop kits that focus on interacting with the natural environment on the field of energy.. the main objective lies on harvesting energy of the natural environment, through wind turbines. These power kits will be scalable and can be used both as pedagogical material and to set up site-specific power plants in different sites as well. There is a counter-infrastructural component to this work: one possible consequence would be to empower people to generate their own energy instead of relying on large and often extractive companies.<br />
<br />
== Introduction and values of the process ==<br />
<br />
Here starts the documentation of the long process of the prototyping the Hugh Piggott The Piggott Turbine – Wind Empowerment model of an Open source wind turbine. We were changing a bit the goals of the event from developing small kits to going to build the real 2m size wind turbine to provide energy to the rural regional areas we were working on. In that specific event we were working at The Foundry a nice project and association that we have settled on the north part of GaliZA into the Northwest of Spain.<br />
<br />
During the event many things have been activated between the doers and the visitors; In general It was a wondering experience full of new things to study, learn, doing and understand together. <br />
<br />
We chose this model because It was full of layers of interest on the levels of learning, understanding and making it, here some levels mixed up with layers: <br />
<br />
first to all is one of the ones that is '''open source''' or at least has the option to access the full documentation.<br />
<br />
really '''rich on the pedagogical level''', we were really learning through the complete building of the generator itself, about many topics as :<br />
* electromagnetism<br />
* mathematics<br />
* geometry<br />
* electronics<br />
* AC-DC<br />
* welding<br />
* wood carving<br />
* sculpting and casting pieces<br />
and much more that was reaching through the nice process of reading, learning and building together.<br />
<br />
== Glossary ==<br />
<br />
* '''AC-'''Alternating current as produced by the alternator. All thread - USA word for 'threaded' or 'spun' rod or studding<br />
* '''Brake switch''' - A switch used to short-circuit the wires from the alternator so that it stops.<br />
* '''Catalyst''' - A chemical used to make the polyester resin set solid. Catalyst reacts with 'accelerator' already present in the resin mix. <br />
The heat of reaction sets the polyester.<br />
* '''Cavalier''' - A make of car. The cavalier in the UK is not the same as the Cavalier in the USA but both have useful wheel hubs.<br />
* '''DC - direct current''' with a positive and a negative side, as in battery circuits.<br />
* '''Diameter''' - The distance from one side of a circle to another. The width of a disk right across the middle.<br />
* '''Phase''' - The timing of the cyclical alternation of voltage in a circuit. Different phases will peak at different times.<br />
* '''Polyester''' - A type of resin used in fibreglass work. Also suitable for making castings.<br />
* '''Power''' - the rate of delivery of energy<br />
* '''Rectifier''' - A semiconductor device that turns AC into DC for charging the battery.<br />
* '''Root''' - The widest part of the blade near to the hub at the center of the rotor.<br />
* '''Rotor''' - A rotating part. Magnet rotors are the steel diskscarrying the magnets past the stator. Rotor blades are the 'propeller' <br />
driven by the wind and driving the magnet rotors.<br />
* '''Soldering''' - A method for making electrical connections between wires using a hot 'iron' and coating everything with molten solder.<br />
* '''Drag''' - A force exerted by the wind on an object. Drag is parallel to the wind direction at the object. (see Lift) <br />
* '''Stator''' - An assembly of coils embedded in a slab of resin to form part of the alternator. The magnets induce a voltage in the coils and we can use this to charge a battery.<br />
* '''Drop''' - Used here to describe a certain measurement of the shape of a windmill blade. The 'drop' affects the angle of<br />
the blade to the wind. Styrene monomer - A nasty smelling solvent in the polyester resin mix.<br />
* '''Flux''' - The 'stuff' of magnetism. Similar to 'current' in electricity. It can be visualized as 'lines' coming out of one pole and <br />
returning to the other.<br />
* '''Furling''' - A protective action that reduces exposure to violent winds by facing the blades away from them.<br />
* '''Jig''' - A device used to hold the magnets in place before setting them in resin.<br />
* '''Leading edge''' - The edge of a blade that would strike an object placed in its path as the rotor spins.<br />
* '''Lift''' - A force exerted by the wind on an object. Lift is at right angles to the wind direction at the object. (see Drag)<br />
* '''Mold''' - A shaped container in which resin castings are formed. The mould can be discarded after the casting has set.<br />
* '''Multimeter''' - A versatile electrical test instrument, used to measure voltage, current and other parameters.<br />
* '''Neodymium''' - The name given to a type of permanent magnet containing neodymium, iron and boron. These magnets are very strong and <br />
getting cheaper all the time.<br />
* '''Offset''' - An eccentric position, off centre.<br />
* '''Talcum powder'''- A cheap filler powder used to thicken the resin and slow its reaction (prevent it overheating).<br />
* '''Tail''' - A projecting vane mounted on a boom at the back ofthe windmill used to steer it into or out of the wind automatically.<br />
* '''Tap''' - a tool for making thread inside holes so you can fit a screw into the hole.<br />
* '''Thrust''' - The force of the wind pushing the machine backwards.<br />
* '''Tower''' - The mast supporting the windmill.<br />
* '''Trailing edge''' - The blade edge furthest from the leading edge. The trailing edge is sharpened, so as to release the passing <br />
air without turbulence.<br />
* '''Wedges''' - Tapered pieces of wood used to build up the blade thickness and increase its angle to the wind near the root.<br />
* '''Work-piece''' - The piece of wood or metal being shaped in the workshop.<br />
* '''Yaw bearing''' - the swivel at the top of the tower on which the windmill is mounted. The yaw bearing allows the windmill to face the wind.<br />

=== The Foundry ===<br />
The Foundry is a non-profit organization based in a previously abandoned GaliZA village. It functions both as a residency and as a project space. It subscribes to the ideals of self-organization, and has the following three objectives:<br />
1. Organizing activities in the field of the arts, science and humanities outside of traditional institutions, focusing on critical discourse.<br />
2. Promoting the exchange of ideas and intellectual collaboration outside of the constraints imposed by state and market.<br />
3. Increasing self-sufficiency, sustainability, and an awareness of the environment using appropriate technology and open source as main resources.<br />
Taking into account this context, our aim is to reinforce the capacity to generate networks flowing from rural to urban context supporting non hierarchy and democratic exchanges of knowledge and practices that can enable new and sustainable models within rural contexts. According to that we consider that the new trans-disciplinary creative sectors in which we are entangled can have a huge and positive impact in the creation of this new paradigm. https://bravosfoundry.com/<br />
Aside from that, there is thematic focus on transdisciplinarity, transfeminism and post-humanism. While this focus is not adequately grasped by identity-political categories like race or gender, we hope it leads to the subversion of hegemonic structures inscribed in the binarisms upholding many of these categories. Our interest lies in the development of tools and technologies that subvert contemporary structures of domination, exploitation and marginalization, not in those that reproduce it.<br />
We seek to develop a more sustainable environment by opening up our practices based on a free culture framework, generating networks and interest around them, enabling a flow of exchange of innovation across creative sectors focusing on revaluation of rural contexts and its knowledge heritage.<br />

=== '''Section 2, involves the construction of '''the alternator''' parts using the devices from the section 1.''' ===<br />
<br />
'''Alternator'''<br />
Each magnet rotor is a steel disk with 12 magnets placed on it and set in resin. The magnets are each 50 x 50 x 20 mm, and they only just fit on the disk. The idea is to achieve the maximum amount of flux in a given space.<br />
The turbine runs at 650 rpm for 400W output, so the centrifugal force on the magnets is 60 times the force of gravity. To prevent them flying off, the resin casting needs to be reinforced. Stainless steel wire rope is placed around the outside of the magnets to hold the casting together at high rpm. We use stainless because it is non-magnetic, or at least less magnetic than normal steel wire rope. <br />
<br />
You will wind the coils that produce the output power and cast them in resin to form a stator between the two magnet rotors. Photos of the final pieces here <br />

<br />
[[File:prod05.jpg|300px]] <br />
<br />
Step - Generator, rotor: Preparation of the wheel hub.<br />
<br />
[[File:frame10.jpg|300px]]<br />
<br />
'''The wheel hub'''<br />
<br />
You can find a used car rear wheel hub (Golf, Toyota, etc.) that has a simple way to<br />
attach the axle, or alternatively buy a trailer hubs online new at low cost.<br />
PCD or ‘pitch circle diameter' is the diameter of the circle of the hole pattern in the<br />
hub, and usually this will be 100mm for a car wheel hub, or 4 inches for a trailer hub.<br />
Car hubs may have a brake-drum that you do not need. This can be removed using a<br />
cutting disk on a grinder. The simplest approach is to make four straight cuts around<br />
the four holes in the front, leaving a square surface to which you mount the magnet<br />
rotors. These photos show a golf rear wheel hub – first the brake-drum being cut, and<br />
then the finished hub after cutting off the drum.A typical rear wheel car hub with a <br />
flange on the back end of the stub shaft that can reused to mount it.<br />
Trailer hubs on the other hand are rather basic quality, and the bearings may be too<br />
cheap for long term use, but they are readily available items that can be purchased<br />
online as new. The drawings below (from autow.com) show a typical hub and stub<br />
axle which are bought separately.<br />
You need to be ready to replace the bearings with a named brand (such as SKF). It’s<br />
easy to replace the inner cones and rollers but the outer shells need to be knocked<br />
gently out of the hub with a suitable drift. Keep them straight by tapping evenly on<br />
opposite sides, and take care not to scratch the seating.<br />

=== Section 4, involves the craving of the blades and the welding of the base for the turbine generator. ===<br />
<br />
4.1 Making the blades <br />
The drawknife is useful for thicker chunks of wood, and for cutting down into a hollow. <br />
It can make a nice smooth job of the root of the blade, whereas the plane will work better <br />
where you need a very straight finish.<br />
<br />
'''Marking the stations.'''<br />
<br />
Place the blade with its best edge toward you on its upper surface. This will actually<br />
become the back or ‘downwind’ side of the finished blade.<br />
(Most of the front or windward side is to be cut off, so defects on this underneath side<br />
are not important.)<br />
<br />
The root of the blade will be on your right, the tip at the left, 1000 mm from the root<br />
(near the left end).<br />
<br />
Measure from the root, and mark four stations.<br />
Station A at 75mm<br />
Station B at 150 mm<br />
Station C at 500 mm<br />
The Tip at 1000 mm.<br />
<br />
<br />
At each station draw a line right around the workpiece using a square.<br />
<br />
[[File:01tur.jpeg|400px]]<br />
<br />
<br />
'''Tapering the blade'''<br />
The width of the blade tapers down from full size at station C to 55 mm wide at the<br />
tip. Mark the 55 mm tip width, measuring from the leading edge side. Draw a line<br />
though your mark to the trailing edge side at C station and cut off a triangular piece so<br />
as to achieve the correct tapered shape for the blade. Any knots in the triangular<br />
off cut do not matter as this piece is discarded. Try to make this a "square" cut,<br />
perpendicular to the back surface of the blade.<br />
You can do this with a circular saw, or by cross-cutting and shaving as described<br />
above.<br />
<br />
<br />
[[File:02tur.jpeg|400px]]<br />
<br />
'''Marking the leading and trailing edges'''<br />
The next step is to cut the windward face of the blade. This face is defined by the<br />
leading and trailing edge lines of the blade. These lines need to be marked with<br />
reference to the back face of the wood which has been uppermost in the previous<br />
operation.<br />
<br />
Turn the wood over. Start by drawing two diagonal lines between stations A and B<br />
on the front or windward side (see below). One is on the front face and the other on<br />
the trailing edge which is now toward you. <br />
<br />
[[File:03tur.jpeg|400px]]<br />
<br />
<br />
Now draw the leading edge line as shown below, <br />
from station B, down to 16mm(from the back) at station C, then continuing to the tip at<br />
7mm from the back.<br />
<br />
[[File:04tur.jpeg|400px]]<br />
<br />
<br />
(This drawing does not show the extra bit beyond the tip which may remain <br />
in your actual workpiece.)<br />
<br />
Measurements are summarised in this table below. Heights are from the back of the<br />
blade which will then rest on the bench. Remove the wood above this height. "Full"<br />
refers to the full thickness of the original piece of wood you are using.<br />
<br />
<br />
<br />
[[File:05tur.jpeg|400px]]<br />
<br />
<br />
'''The trailing''' <br />
The trailing edge line starts at the bottom of the diagonal line at station B, and <br />
rises to 5mm at C, continuing at 5 mm to the tip. This view below shows the wood <br />
already removed between the two lines to form the windward face of the blade.<br />
<br />
<br />
[[File:06tur.png|400px]]<br />
<br />
<br />
Carve this flat windward face between the 2 lines. Take care that the edges are<br />
straight, following the lines. The best tool to use for finishing the outer part of the<br />
blade is a plane, to give a smooth, straight finish. You may need to work the plane at<br />
45 degrees to the workpiece, sliding partly sideways, to form the hollow shape at<br />
station C.<br />
<br />
This step is completed when you can place a ruler across the face between the leading<br />
and trailing edge lines and there is no ‘hump’ in the middle. Fill any chips or small<br />
hollows with wood filler. If there are any serious errors, or large knots that weaken<br />
the blade then it may have to be discarded.<br />
Check the “drop” using a level as a reference. Clamp the wood so that the root part<br />
sits level, and measure the difference in level between the leading and trailing edges.<br />
The difference or “drop” should be 11 mm at the 500 mm mid-point, and 2 mm at the<br />
tip.<br />

O principal obxectivo deste evento é prototipar un xerador eólico a pequena escala para camiñar xuntos cara á autosuficiencia neste campo.<br />
Temos o pracer de comunicarvos que do 16 ao 23 de outubro Biotranslab de Pin e The Foundry establecen unha colaboración para levar a cabo o evento Eco (i) Logic Queer Energy harvesting. O proxecto é posible grazas ao apoio de GOSH, unha rede para desenvolver e difundir proxectos baseados en hardware de código aberto para a ciencia.<br />
<br />
EcoLoxicas Queer para a captación de enerxía eolica. <br />
O evento ten como obxectivo abordar a falta de mulleres, queer, trans e diversidade nos ámbitos tecnolóxicos en xeral e do hacking máis concretamente. Pero aínda máis, pretende crear unha comunidade que avalía criticamente as narrativas hexemónicas arredor das tecnoloxías, os aspectos de modernidade dos seus supostos occidentais subliñados e as súas inflexións capitalistas inherentes, entre outros.<br />
O obxectivo principal do evento é desenvolver kits que se centren na interacción co medio natural no ámbito da enerxía.. o obxectivo principal pasa pola captación de enerxía do medio natural, a través dos aeroxeradores. Estes kits de enerxía serán escalables e poderán utilizarse tanto como material pedagóxico como para instalar centrais eléctricas específicas do sitio en diferentes sitios tamén. Este traballo ten un compoñente contrainfraestrutural: unha posible consecuencia sería capacitar ás persoas para xerar a súa propia enerxía en lugar de depender de grandes empresas e moitas veces extractivas.<br />

''Pedagogies of the Wind and Stars. The social relations that we (were never meant to) survive, also live in our bodies painfully, and Audre Lorde is not here to remind us of this lesson herself, except in as much that she is present in the pedagogical wind. But wind is our teacher (74). -Alexis Pauline Gumbs'' from the book Mapping Queer Space(s) of Praxis and Pedagogy <br />
Editors: Elizabeth McNeil, James E. Wermers, Joshua O. Lunn'' <br />
<br />
We have the pleasure to communicate you that from 16 to 29 of October Pin Biotranslab, Casa do Río e The Foundry establishes a collaboration to run the event Eco (i) Logic Queer Energy harvesting. The project is possible thanks to the support of GOSH, an network for develop and disseminate projects based on Open Source hardware for Science.<br />
<br />
'''Eco (i) Logic Queer Energy harvesting''' <br />
The event aims at addressing the lack of women, queer, trans and diversity in technological fields in general and hacking more specifically. But even more so, it aims at creating a community that critically assesses the hegemonic narratives around technologies, the modernity aspects of its underlining Western assumptions and its inherent capitalist inflections, among others.<br />
The main purpose of the event is to develop kits that focus on interacting with the natural environment on the field of energy.. the main objective lies on harvesting energy of the natural environment, through wind turbines. These power kits will be scalable and can be used both as pedagogical material and to set up site-specific power plants in different sites as well. There is a counter-infrastructural component to this work: one possible consequence would be to empower people to generate their own energy instead of relying on large and often extractive companies.<br />
<br />
== Introduction and values of the process ==<br />
<br />
Here starts the documentation of the long process of the prototyping the Hugh Piggott The Piggott Turbine – Wind Empowerment model of an Open source wind turbine. We were changing a bit the goals of the event from developing small kits to going to build the real 2m size wind turbine to provide energy to the rural regional areas we were working on. In that specific event we were working at The Foundry a nice project and association that we have settled on the north part of GaliZA into the Northwest of Spain.<br />
<br />
During the event many things have been activated between the doers and the visitors; In general It was a wondering experience full of new things to study, learn, doing and understand together. <br />
<br />
We chose this model because It was full of layers of interest on the levels of learning, understanding and making it, here some levels mixed up with layers: <br />
<br />
first to all is one of the ones that is '''open source''' or at least has the option to access the full documentation.<br />
<br />
really '''rich on the pedagogical level''', we were really learning through the complete building of the generator itself, about many topics as :<br />
* electromagnetism<br />
* mathematics<br />
* geometry<br />
* electronics<br />
* AC-DC<br />
* welding<br />
* wood carving<br />
* sculpting and casting pieces<br />
and much more that was reaching through the nice process of reading, learning and building together.<br />
<br />
== Glossary ==<br />
<br />
* '''AC-'''Alternating current as produced by the alternator. All thread - USA word for 'threaded' or 'spun' rod or studding<br />
* '''Brake switch''' - A switch used to short-circuit the wires from the alternator so that it stops.<br />
* '''Catalyst''' - A chemical used to make the polyester resin set solid. Catalyst reacts with 'accelerator' already present in the resin mix. <br />
The heat of reaction sets the polyester.<br />
* '''Cavalier''' - A make of car. The cavalier in the UK is not the same as the Cavalier in the USA but both have useful wheel hubs.<br />
* '''DC - direct current''' with a positive and a negative side, as in battery circuits.<br />
* '''Diameter''' - The distance from one side of a circle to another. The width of a disk right across the middle.<br />
* '''Phase''' - The timing of the cyclical alternation of voltage in a circuit. Different phases will peak at different times.<br />
* '''Polyester''' - A type of resin used in fibreglass work. Also suitable for making castings.<br />
* '''Power''' - the rate of delivery of energy<br />
* '''Rectifier''' - A semiconductor device that turns AC into DC for charging the battery.<br />
* '''Root''' - The widest part of the blade near to the hub at the center of the rotor.<br />
* '''Rotor''' - A rotating part. Magnet rotors are the steel diskscarrying the magnets past the stator. Rotor blades are the 'propeller' <br />
driven by the wind and driving the magnet rotors.<br />
* '''Soldering''' - A method for making electrical connections between wires using a hot 'iron' and coating everything with molten solder.<br />
* '''Drag''' - A force exerted by the wind on an object. Drag is parallel to the wind direction at the object. (see Lift) <br />
* '''Stator''' - An assembly of coils embedded in a slab of resin to form part of the alternator. The magnets induce a voltage in the coils and we can use this to charge a battery.<br />
* '''Drop''' - Used here to describe a certain measurement of the shape of a windmill blade. The 'drop' affects the angle of<br />
the blade to the wind. Styrene monomer - A nasty smelling solvent in the polyester resin mix.<br />
* '''Flux''' - The 'stuff' of magnetism. Similar to 'current' in electricity. It can be visualized as 'lines' coming out of one pole and <br />

=== The Foundry ===<br />
The Foundry is a non-profit organization based in a previously abandoned GaliZA village. It functions both as a residency and as a project space. It subscribes to the ideals of self-organization, and has the following three objectives:<br />
1. Organizing activities in the field of the arts, science and humanities outside of traditional institutions, focusing on critical discourse.<br />
2. Promoting the exchange of ideas and intellectual collaboration outside of the constraints imposed by state and market.<br />
3. Increasing self-sufficiency, sustainability, and an awareness of the environment using appropriate technology and open source as main resources.<br />
Taking into account this context, our aim is to reinforce the capacity to generate networks flowing from rural to urban context supporting non hierarchy and democratic exchanges of knowledge and practices that can enable new and sustainable models within rural contexts. According to that we consider that the new trans-disciplinary creative sectors in which we are entangled can have a huge and positive impact in the creation of this new paradigm. https://bravosfoundry.com/<br />
Aside from that, there is thematic focus on transdisciplinarity, transfeminism and post-humanism. While this focus is not adequately grasped by identity-political categories like race or gender, we hope it leads to the subversion of hegemonic structures inscribed in the binarisms upholding many of these categories. Our interest lies in the development of tools and technologies that subvert contemporary structures of domination, exploitation and marginalization, not in those that reproduce it.<br />
We seek to develop a more sustainable environment by opening up our practices based on a free culture framework, generating networks and interest around them, enabling a flow of exchange of innovation across creative sectors focusing on revaluation of rural contexts and its knowledge heritage.<br />

=== '''Section 2, involves the construction of '''the alternator''' parts using the devices from the section 1.''' ===<br />
<br />
'''Alternator'''<br />
Each magnet rotor is a steel disk with 12 magnets placed on it and set in resin. The magnets are each 50 x 50 x 20 mm, and they only just fit on the disk. The idea is to achieve the maximum amount of flux in a given space.<br />
The turbine runs at 650 rpm for 400W output, so the centrifugal force on the magnets is 60 times the force of gravity. To prevent them flying off, the resin casting needs to be reinforced. Stainless steel wire rope is placed around the outside of the magnets to hold the casting together at high rpm. We use stainless because it is non-magnetic, or at least less magnetic than normal steel wire rope. <br />
<br />
You will wind the coils that produce the output power and cast them in resin to form a stator between the two magnet rotors. Photos of the final pieces here <br />

[[File:prod05.jpg|300px]] <br />
<br />
Step - Generator, rotor: Preparation of the wheel hub.<br />
<br />
[[File:frame10.jpg|300px]]<br />
<br />
'''The wheel hub'''<br />
<br />
You can find a used car rear wheel hub (Golf, Toyota, etc.) that has a simple way to<br />
attach the axle, or alternatively buy a trailer hubs online new at low cost.<br />
PCD or ‘pitch circle diameter' is the diameter of the circle of the hole pattern in the<br />
hub, and usually this will be 100mm for a car wheel hub, or 4 inches for a trailer hub.<br />
Car hubs may have a brake-drum that you do not need. This can be removed using a<br />
cutting disk on a grinder. The simplest approach is to make four straight cuts around<br />
the four holes in the front, leaving a square surface to which you mount the magnet<br />
rotors. These photos show a golf rear wheel hub – first the brake-drum being cut, and<br />
then the finished hub after cutting off the drum.A typical rear wheel car hub with a <br />
flange on the back end of the stub shaft that can reused to mount it.<br />
Trailer hubs on the other hand are rather basic quality, and the bearings may be too<br />
cheap for long term use, but they are readily available items that can be purchased<br />
online as new. The drawings below (from autow.com) show a typical hub and stub<br />
axle which are bought separately.<br />
You need to be ready to replace the bearings with a named brand (such as SKF). It’s<br />
easy to replace the inner cones and rollers but the outer shells need to be knocked<br />
gently out of the hub with a suitable drift. Keep them straight by tapping evenly on<br />
opposite sides, and take care not to scratch the seating.<br />

=== Section 4, involves the craving of the blades and the welding of the base for the turbine generator. ===<br />
<br />
4.1 Making the blades <br />
The drawknife is useful for thicker chunks of wood, and for cutting down into a hollow. <br />
It can make a nice smooth job of the root of the blade, whereas the plane will work better <br />
where you need a very straight finish.<br />
<br />
'''Marking the stations.'''<br />
<br />
Place the blade with its best edge toward you on its upper surface. This will actually<br />
become the back or ‘downwind’ side of the finished blade.<br />
(Most of the front or windward side is to be cut off, so defects on this underneath side<br />
are not important.)<br />
<br />
The root of the blade will be on your right, the tip at the left, 1000 mm from the root<br />
(near the left end).<br />
<br />
Measure from the root, and mark four stations.<br />
Station A at 75mm<br />
Station B at 150 mm<br />
Station C at 500 mm<br />
The Tip at 1000 mm.<br />
<br />
<br />
At each station draw a line right around the workpiece using a square.<br />
<br />
[[File:01tur.jpeg|400px]]<br />
<br />
<br />
'''Tapering the blade'''<br />
The width of the blade tapers down from full size at station C to 55 mm wide at the<br />
tip. Mark the 55 mm tip width, measuring from the leading edge side. Draw a line<br />
though your mark to the trailing edge side at C station and cut off a triangular piece so<br />
as to achieve the correct tapered shape for the blade. Any knots in the triangular<br />
off cut do not matter as this piece is discarded. Try to make this a "square" cut,<br />
perpendicular to the back surface of the blade.<br />
You can do this with a circular saw, or by cross-cutting and shaving as described<br />
above.<br />
<br />
<br />
[[File:02tur.jpeg|400px]]<br />
<br />
'''Marking the leading and trailing edges'''<br />
The next step is to cut the windward face of the blade. This face is defined by the<br />
leading and trailing edge lines of the blade. These lines need to be marked with<br />
reference to the back face of the wood which has been uppermost in the previous<br />
operation.<br />
<br />
Turn the wood over. Start by drawing two diagonal lines between stations A and B<br />
on the front or windward side (see below). One is on the front face and the other on<br />
the trailing edge which is now toward you. <br />
<br />
[[File:03tur.jpeg|400px]]<br />
<br />
<br />
Now draw the leading edge line as shown below, <br />
from station B, down to 16mm(from the back) at station C, then continuing to the tip at<br />
7mm from the back.<br />
<br />
[[File:04tur.jpeg|400px]]<br />
<br />
<br />
(This drawing does not show the extra bit beyond the tip which may remain <br />
in your actual workpiece.)<br />
<br />
Measurements are summarised in this table below. Heights are from the back of the<br />
blade which will then rest on the bench. Remove the wood above this height. "Full"<br />
refers to the full thickness of the original piece of wood you are using.<br />
<br />
<br />
<br />
[[File:05tur.jpeg|400px]]<br />
<br />
<br />
'''The trailing''' <br />
The trailing edge line starts at the bottom of the diagonal line at station B, and <br />
rises to 5mm at C, continuing at 5 mm to the tip. This view below shows the wood <br />
already removed between the two lines to form the windward face of the blade.<br />
<br />
<br />
[[File:06tur.png|400px]]<br />
<br />
<br />
Carve this flat windward face between the 2 lines. Take care that the edges are<br />
straight, following the lines. The best tool to use for finishing the outer part of the<br />
blade is a plane, to give a smooth, straight finish. You may need to work the plane at<br />
45 degrees to the workpiece, sliding partly sideways, to form the hollow shape at<br />
station C.<br />
<br />
This step is completed when you can place a ruler across the face between the leading<br />
and trailing edge lines and there is no ‘hump’ in the middle. Fill any chips or small<br />
hollows with wood filler. If there are any serious errors, or large knots that weaken<br />
the blade then it may have to be discarded.<br />
Check the “drop” using a level as a reference. Clamp the wood so that the root part<br />
sits level, and measure the difference in level between the leading and trailing edges.<br />
The difference or “drop” should be 11 mm at the 500 mm mid-point, and 2 mm at the<br />
tip.<br />

O principal obxectivo deste evento é prototipar un xerador eólico a pequena escala para camiñar xuntos cara á autosuficiencia neste campo.<br />
Temos o pracer de comunicarvos que do 16 ao 23 de outubro Biotranslab de Pin e The Foundry establecen unha colaboración para levar a cabo o evento Eco (i) Logic Queer Energy harvesting. O proxecto é posible grazas ao apoio de GOSH, unha rede para desenvolver e difundir proxectos baseados en hardware de código aberto para a ciencia.<br />
<br />
EcoLoxicas Queer para a captación de enerxía eolica. <br />
O evento ten como obxectivo abordar a falta de mulleres, queer, trans e diversidade nos ámbitos tecnolóxicos en xeral e do hacking máis concretamente. Pero aínda máis, pretende crear unha comunidade que avalía criticamente as narrativas hexemónicas arredor das tecnoloxías, os aspectos de modernidade dos seus supostos occidentais subliñados e as súas inflexións capitalistas inherentes, entre outros.<br />
O obxectivo principal do evento é desenvolver kits que se centren na interacción co medio natural no ámbito da enerxía.. o obxectivo principal pasa pola captación de enerxía do medio natural, a través dos aeroxeradores. Estes kits de enerxía serán escalables e poderán utilizarse tanto como material pedagóxico como para instalar centrais eléctricas específicas do sitio en diferentes sitios tamén. Este traballo ten un compoñente contrainfraestrutural: unha posible consecuencia sería capacitar ás persoas para xerar a súa propia enerxía en lugar de depender de grandes empresas e moitas veces extractivas.<br />

''Pedagogies of the Wind and Stars. The social relations that we (were never meant to) survive, also live in our bodies painfully, and Audre Lorde is not here to remind us of this lesson herself, except in as much that she is present in the pedagogical wind. But wind is our teacher (74). -Alexis Pauline Gumbs'' from the book Mapping Queer Space(s) of Praxis and Pedagogy <br />
Editors: Elizabeth McNeil, James E. Wermers, Joshua O. Lunn'' <br />
<br />
We have the pleasure to communicate you that from 16 to 29 of October Pin Biotranslab, Casa do Río e The Foundry establishes a collaboration to run the event Eco (i) Logic Queer Energy harvesting. The project is possible thanks to the support of GOSH, an network for develop and disseminate projects based on Open Source hardware for Science.<br />
<br />
'''Eco (i) Logic Queer Energy harvesting''' <br />
The event aims at addressing the lack of women, queer, trans and diversity in technological fields in general and hacking more specifically. But even more so, it aims at creating a community that critically assesses the hegemonic narratives around technologies, the modernity aspects of its underlining Western assumptions and its inherent capitalist inflections, among others.<br />
The main purpose of the event is to develop kits that focus on interacting with the natural environment on the field of energy.. the main objective lies on harvesting energy of the natural environment, through wind turbines. These power kits will be scalable and can be used both as pedagogical material and to set up site-specific power plants in different sites as well. There is a counter-infrastructural component to this work: one possible consequence would be to empower people to generate their own energy instead of relying on large and often extractive companies.<br />
<br />
== Introduction and values of the process ==<br />
<br />
Here starts the documentation of the long process of the prototyping the Hugh Piggott The Piggott Turbine – Wind Empowerment model of an Open source wind turbine. We were changing a bit the goals of the event from developing small kits to going to build the real 2m size wind turbine to provide energy to the rural regional areas we were working on. In that specific event we were working at The Foundry a nice project and association that we have settled on the north part of GaliZA into the Northwest of Spain.<br />
<br />
During the event many things have been activated between the doers and the visitors; In general It was a wondering experience full of new things to study, learn, doing and understand together. <br />
<br />
We chose this model because It was full of layers of interest on the levels of learning, understanding and making it, here some levels mixed up with layers: <br />
<br />
first to all is one of the ones that is '''open source''' or at least has the option to access the full documentation.<br />
<br />
really '''rich on the pedagogical level''', we were really learning through the complete building of the generator itself, about many topics as :<br />
* electromagnetism<br />
* mathematics<br />
* geometry<br />
* electronics<br />
* AC-DC<br />
* welding<br />
* wood carving<br />
* sculpting and casting pieces<br />
and much more that was reaching through the nice process of reading, learning and building together.<br />
<br />
== Glossary ==<br />
<br />
* '''AC-'''Alternating current as produced by the alternator. All thread - USA word for 'threaded' or 'spun' rod or studding<br />
* '''Brake switch''' - A switch used to short-circuit the wires from the alternator so that it stops.<br />
* '''Catalyst''' - A chemical used to make the polyester resin set solid. Catalyst reacts with 'accelerator' already present in the resin mix. <br />
The heat of reaction sets the polyester.<br />
* '''Cavalier''' - A make of car. The cavalier in the UK is not the same as the Cavalier in the USA but both have useful wheel hubs.<br />
* '''DC - direct current''' with a positive and a negative side, as in battery circuits.<br />
* '''Diameter''' - The distance from one side of a circle to another. The width of a disk right across the middle.<br />
* '''Phase''' - The timing of the cyclical alternation of voltage in a circuit. Different phases will peak at different times.<br />
* '''Polyester''' - A type of resin used in fibreglass work. Also suitable for making castings.<br />
* '''Power''' - the rate of delivery of energy<br />
* '''Rectifier''' - A semiconductor device that turns AC into DC for charging the battery.<br />
* '''Root''' - The widest part of the blade near to the hub at the center of the rotor.<br />
* '''Rotor''' - A rotating part. Magnet rotors are the steel diskscarrying the magnets past the stator. Rotor blades are the 'propeller' <br />
driven by the wind and driving the magnet rotors.<br />
* '''Soldering''' - A method for making electrical connections between wires using a hot 'iron' and coating everything with molten solder.<br />
* '''Drag''' - A force exerted by the wind on an object. Drag is parallel to the wind direction at the object. (see Lift) <br />
* '''Stator''' - An assembly of coils embedded in a slab of resin to form part of the alternator. The magnets induce a voltage in the coils and we can use this to charge a battery.<br />
* '''Drop''' - Used here to describe a certain measurement of the shape of a windmill blade. The 'drop' affects the angle of<br />
the blade to the wind. Styrene monomer - A nasty smelling solvent in the polyester resin mix.<br />
* '''Flux''' - The 'stuff' of magnetism. Similar to 'current' in electricity. It can be visualized as 'lines' coming out of one pole and <br />
returning to the other.<br />
* '''Furling''' - A protective action that reduces exposure to violent winds by facing the blades away from them.<br />
* '''Jig''' - A device used to hold the magnets in place before setting them in resin.<br />
* '''Leading edge''' - The edge of a blade that would strike an object placed in its path as the rotor spins.<br />
* '''Lift''' - A force exerted by the wind on an object. Lift is at right angles to the wind direction at the object. (see Drag)<br />
* '''Mold''' - A shaped container in which resin castings are formed. The mould can be discarded after the casting has set.<br />
* '''Multimeter''' - A versatile electrical test instrument, used to measure voltage, current and other parameters.<br />
* '''Neodymium''' - The name given to a type of permanent magnet containing neodymium, iron and boron. These magnets are very strong and <br />
getting cheaper all the time.<br />
* '''Offset''' - An eccentric position, off centre.<br />
* '''Talcum powder'''- A cheap filler powder used to thicken the resin and slow its reaction (prevent it overheating).<br />
* '''Tail''' - A projecting vane mounted on a boom at the back ofthe windmill used to steer it into or out of the wind automatically.<br />
* '''Tap''' - a tool for making thread inside holes so you can fit a screw into the hole.<br />
* '''Thrust''' - The force of the wind pushing the machine backwards.<br />
* '''Tower''' - The mast supporting the windmill.<br />
* '''Trailing edge''' - The blade edge furthest from the leading edge. The trailing edge is sharpened, so as to release the passing <br />
air without turbulence.<br />
* '''Wedges''' - Tapered pieces of wood used to build up the blade thickness and increase its angle to the wind near the root.<br />
* '''Work-piece''' - The piece of wood or metal being shaped in the workshop.<br />

=== The Foundry ===<br />
The Foundry is a non-profit organization based in a previously abandoned GaliZA village. It functions both as a residency and as a project space. It subscribes to the ideals of self-organization, and has the following three objectives:<br />
1. Organizing activities in the field of the arts, science and humanities outside of traditional institutions, focusing on critical discourse.<br />
2. Promoting the exchange of ideas and intellectual collaboration outside of the constraints imposed by state and market.<br />
3. Increasing self-sufficiency, sustainability, and an awareness of the environment using appropriate technology and open source as main resources.<br />
Taking into account this context, our aim is to reinforce the capacity to generate networks flowing from rural to urban context supporting non hierarchy and democratic exchanges of knowledge and practices that can enable new and sustainable models within rural contexts. According to that we consider that the new trans-disciplinary creative sectors in which we are entangled can have a huge and positive impact in the creation of this new paradigm. https://bravosfoundry.com/<br />
Aside from that, there is thematic focus on transdisciplinarity, transfeminism and post-humanism. While this focus is not adequately grasped by identity-political categories like race or gender, we hope it leads to the subversion of hegemonic structures inscribed in the binarisms upholding many of these categories. Our interest lies in the development of tools and technologies that subvert contemporary structures of domination, exploitation and marginalization, not in those that reproduce it.<br />
We seek to develop a more sustainable environment by opening up our practices based on a free culture framework, generating networks and interest around them, enabling a flow of exchange of innovation across creative sectors focusing on revaluation of rural contexts and its knowledge heritage.<br />

=== '''Section 2, involves the construction of '''the alternator''' parts using the devices from the section 1.''' ===<br />
<br />
'''Alternator'''<br />
Each magnet rotor is a steel disk with 12 magnets placed on it and set in resin. The magnets are each 50 x 50 x 20 mm, and they only just fit on the disk. The idea is to achieve the maximum amount of flux in a given space.<br />
The turbine runs at 650 rpm for 400W output, so the centrifugal force on the magnets is 60 times the force of gravity. To prevent them flying off, the resin casting needs to be reinforced. Stainless steel wire rope is placed around the outside of the magnets to hold the casting together at high rpm. We use stainless because it is non-magnetic, or at least less magnetic than normal steel wire rope. <br />
<br />
You will wind the coils that produce the output power and cast them in resin to form a stator between the two magnet rotors. Photos of the final pieces here <br />

<br />
[[File:prod05.jpg|300px]] <br />
<br />
Step - Generator, rotor: Preparation of the wheel hub.<br />
<br />
[[File:frame10.jpg|300px]]<br />
<br />
'''The wheel hub'''<br />
<br />
You can find a used car rear wheel hub (Golf, Toyota, etc.) that has a simple way to<br />
attach the axle, or alternatively buy a trailer hubs online new at low cost.<br />
PCD or ‘pitch circle diameter' is the diameter of the circle of the hole pattern in the<br />
hub, and usually this will be 100mm for a car wheel hub, or 4 inches for a trailer hub.<br />
Car hubs may have a brake-drum that you do not need. This can be removed using a<br />
cutting disk on a grinder. The simplest approach is to make four straight cuts around<br />
the four holes in the front, leaving a square surface to which you mount the magnet<br />
rotors. These photos show a golf rear wheel hub – first the brake-drum being cut, and<br />
then the finished hub after cutting off the drum.A typical rear wheel car hub with a <br />
flange on the back end of the stub shaft that can reused to mount it.<br />
Trailer hubs on the other hand are rather basic quality, and the bearings may be too<br />
cheap for long term use, but they are readily available items that can be purchased<br />
online as new. The drawings below (from autow.com) show a typical hub and stub<br />
axle which are bought separately.<br />
You need to be ready to replace the bearings with a named brand (such as SKF). It’s<br />
easy to replace the inner cones and rollers but the outer shells need to be knocked<br />
gently out of the hub with a suitable drift. Keep them straight by tapping evenly on<br />
opposite sides, and take care not to scratch the seating.<br />

=== Section 4, involves the craving of the blades and the welding of the base for the turbine generator. ===<br />
<br />
4.1 Making the blades <br />
The drawknife is useful for thicker chunks of wood, and for cutting down into a hollow. <br />
It can make a nice smooth job of the root of the blade, whereas the plane will work better <br />
where you need a very straight finish.<br />
<br />
'''Marking the stations.'''<br />
<br />
Place the blade with its best edge toward you on its upper surface. This will actually<br />
become the back or ‘downwind’ side of the finished blade.<br />
(Most of the front or windward side is to be cut off, so defects on this underneath side<br />
are not important.)<br />
<br />
The root of the blade will be on your right, the tip at the left, 1000 mm from the root<br />
(near the left end).<br />
<br />
Measure from the root, and mark four stations.<br />
Station A at 75mm<br />
Station B at 150 mm<br />
Station C at 500 mm<br />
The Tip at 1000 mm.<br />
<br />
<br />
At each station draw a line right around the workpiece using a square.<br />
<br />
[[File:01tur.jpeg|400px]]<br />
<br />
<br />
'''Tapering the blade'''<br />
The width of the blade tapers down from full size at station C to 55 mm wide at the<br />
tip. Mark the 55 mm tip width, measuring from the leading edge side. Draw a line<br />
though your mark to the trailing edge side at C station and cut off a triangular piece so<br />
as to achieve the correct tapered shape for the blade. Any knots in the triangular<br />
off cut do not matter as this piece is discarded. Try to make this a "square" cut,<br />
perpendicular to the back surface of the blade.<br />
You can do this with a circular saw, or by cross-cutting and shaving as described<br />
above.<br />
<br />
<br />
[[File:02tur.jpeg|400px]]<br />
<br />
'''Marking the leading and trailing edges'''<br />
The next step is to cut the windward face of the blade. This face is defined by the<br />
leading and trailing edge lines of the blade. These lines need to be marked with<br />
reference to the back face of the wood which has been uppermost in the previous<br />
operation.<br />
<br />
Turn the wood over. Start by drawing two diagonal lines between stations A and B<br />
on the front or windward side (see below). One is on the front face and the other on<br />
the trailing edge which is now toward you. <br />
<br />
[[File:03tur.jpeg|400px]]<br />
<br />
<br />
Now draw the leading edge line as shown below, <br />
from station B, down to 16mm(from the back) at station C, then continuing to the tip at<br />
7mm from the back.<br />
<br />
[[File:04tur.jpeg|400px]]<br />
<br />
<br />
(This drawing does not show the extra bit beyond the tip which may remain <br />
in your actual workpiece.)<br />
<br />
Measurements are summarised in this table below. Heights are from the back of the<br />
blade which will then rest on the bench. Remove the wood above this height. "Full"<br />
refers to the full thickness of the original piece of wood you are using.<br />
<br />
<br />
<br />
[[File:05tur.jpeg|400px]]<br />
<br />
<br />
'''The trailing''' <br />
The trailing edge line starts at the bottom of the diagonal line at station B, and <br />
rises to 5mm at C, continuing at 5 mm to the tip. This view below shows the wood <br />
already removed between the two lines to form the windward face of the blade.<br />
<br />
<br />
[[File:06tur.png|400px]]<br />
<br />
<br />
Carve this flat windward face between the 2 lines. Take care that the edges are<br />
straight, following the lines. The best tool to use for finishing the outer part of the<br />
blade is a plane, to give a smooth, straight finish. You may need to work the plane at<br />
45 degrees to the workpiece, sliding partly sideways, to form the hollow shape at<br />
station C.<br />
<br />
This step is completed when you can place a ruler across the face between the leading<br />
and trailing edge lines and there is no ‘hump’ in the middle. Fill any chips or small<br />
hollows with wood filler. If there are any serious errors, or large knots that weaken<br />
the blade then it may have to be discarded.<br />
Check the “drop” using a level as a reference. Clamp the wood so that the root part<br />
sits level, and measure the difference in level between the leading and trailing edges.<br />
The difference or “drop” should be 11 mm at the 500 mm mid-point, and 2 mm at the<br />
tip.<br />

O principal obxectivo deste evento é prototipar un xerador eólico a pequena escala para camiñar xuntos cara á autosuficiencia neste campo.<br />
Temos o pracer de comunicarvos que do 16 ao 23 de outubro Biotranslab de Pin e The Foundry establecen unha colaboración para levar a cabo o evento Eco (i) Logic Queer Energy harvesting. O proxecto é posible grazas ao apoio de GOSH, unha rede para desenvolver e difundir proxectos baseados en hardware de código aberto para a ciencia.<br />
<br />
EcoLoxicas Queer para a captación de enerxía eolica. <br />
O evento ten como obxectivo abordar a falta de mulleres, queer, trans e diversidade nos ámbitos tecnolóxicos en xeral e do hacking máis concretamente. Pero aínda máis, pretende crear unha comunidade que avalía criticamente as narrativas hexemónicas arredor das tecnoloxías, os aspectos de modernidade dos seus supostos occidentais subliñados e as súas inflexións capitalistas inherentes, entre outros.<br />
O obxectivo principal do evento é desenvolver kits que se centren na interacción co medio natural no ámbito da enerxía.. o obxectivo principal pasa pola captación de enerxía do medio natural, a través dos aeroxeradores. Estes kits de enerxía serán escalables e poderán utilizarse tanto como material pedagóxico como para instalar centrais eléctricas específicas do sitio en diferentes sitios tamén. Este traballo ten un compoñente contrainfraestrutural: unha posible consecuencia sería capacitar ás persoas para xerar a súa propia enerxía en lugar de depender de grandes empresas e moitas veces extractivas.<br />

''Pedagogies of the Wind and Stars. The social relations that we (were never meant to) survive, also live in our bodies painfully, and Audre Lorde is not here to remind us of this lesson herself, except in as much that she is present in the pedagogical wind. But wind is our teacher (74). -Alexis Pauline Gumbs'' from the book Mapping Queer Space(s) of Praxis and Pedagogy <br />
Editors: Elizabeth McNeil, James E. Wermers, Joshua O. Lunn'' <br />
<br />
We have the pleasure to communicate you that from 16 to 29 of October Pin Biotranslab, Casa do Río e The Foundry establishes a collaboration to run the event Eco (i) Logic Queer Energy harvesting. The project is possible thanks to the support of GOSH, an network for develop and disseminate projects based on Open Source hardware for Science.<br />
<br />
'''Eco (i) Logic Queer Energy harvesting''' <br />
The event aims at addressing the lack of women, queer, trans and diversity in technological fields in general and hacking more specifically. But even more so, it aims at creating a community that critically assesses the hegemonic narratives around technologies, the modernity aspects of its underlining Western assumptions and its inherent capitalist inflections, among others.<br />
The main purpose of the event is to develop kits that focus on interacting with the natural environment on the field of energy.. the main objective lies on harvesting energy of the natural environment, through wind turbines. These power kits will be scalable and can be used both as pedagogical material and to set up site-specific power plants in different sites as well. There is a counter-infrastructural component to this work: one possible consequence would be to empower people to generate their own energy instead of relying on large and often extractive companies.<br />
<br />
== Introduction and values of the process ==<br />
<br />
Here starts the documentation of the long process of the prototyping the Hugh Piggott The Piggott Turbine – Wind Empowerment model of an Open source wind turbine. We were changing a bit the goals of the event from developing small kits to going to build the real 2m size wind turbine to provide energy to the rural regional areas we were working on. In that specific event we were working at The Foundry a nice project and association that we have settled on the north part of GaliZA into the Northwest of Spain.<br />
<br />
During the event many things have been activated between the doers and the visitors; In general It was a wondering experience full of new things to study, learn, doing and understand together. <br />
<br />
We chose this model because It was full of layers of interest on the levels of learning, understanding and making it, here some levels mixed up with layers: <br />
<br />
first to all is one of the ones that is '''open source''' or at least has the option to access the full documentation.<br />
<br />
really '''rich on the pedagogical level''', we were really learning through the complete building of the generator itself, about many topics as :<br />
* electromagnetism<br />
* mathematics<br />
* geometry<br />
* electronics<br />
* AC-DC<br />
* welding<br />
* wood carving<br />
* sculpting and casting pieces<br />
and much more that was reaching through the nice process of reading, learning and building together.<br />
<br />
== Glossary ==<br />
<br />
* '''AC-'''Alternating current as produced by the alternator. All thread - USA word for 'threaded' or 'spun' rod or studding<br />
* '''Brake switch''' - A switch used to short-circuit the wires from the alternator so that it stops.<br />
* '''Catalyst''' - A chemical used to make the polyester resin set solid. Catalyst reacts with 'accelerator' already present in the resin mix. <br />
The heat of reaction sets the polyester.<br />
* '''Cavalier''' - A make of car. The cavalier in the UK is not the same as the Cavalier in the USA but both have useful wheel hubs.<br />
* '''DC - direct current''' with a positive and a negative side, as in battery circuits.<br />
* '''Diameter''' - The distance from one side of a circle to another. The width of a disk right across the middle.<br />
* '''Phase''' - The timing of the cyclical alternation of voltage in a circuit. Different phases will peak at different times.<br />
* '''Polyester''' - A type of resin used in fibreglass work. Also suitable for making castings.<br />
* '''Power''' - the rate of delivery of energy<br />
* '''Rectifier''' - A semiconductor device that turns AC into DC for charging the battery.<br />
* '''Root''' - The widest part of the blade near to the hub at the center of the rotor.<br />
* '''Rotor''' - A rotating part. Magnet rotors are the steel diskscarrying the magnets past the stator. Rotor blades are the 'propeller' <br />
driven by the wind and driving the magnet rotors.<br />
* '''Soldering''' - A method for making electrical connections between wires using a hot 'iron' and coating everything with molten solder.<br />
* '''Drag''' - A force exerted by the wind on an object. Drag is parallel to the wind direction at the object. (see Lift) <br />
* '''Stator''' - An assembly of coils embedded in a slab of resin to form part of the alternator. The magnets induce a voltage in the coils and we can use this to charge a battery.<br />
* '''Drop''' - Used here to describe a certain measurement of the shape of a windmill blade. The 'drop' affects the angle of<br />
the blade to the wind. Styrene monomer - A nasty smelling solvent in the polyester resin mix.<br />
* '''Flux''' - The 'stuff' of magnetism. Similar to 'current' in electricity. It can be visualized as 'lines' coming out of one pole and <br />
returning to the other.<br />
* '''Furling''' - A protective action that reduces exposure to violent winds by facing the blades away from them.<br />
* '''Jig''' - A device used to hold the magnets in place before setting them in resin.<br />
* '''Leading edge''' - The edge of a blade that would strike an object placed in its path as the rotor spins.<br />
* '''Lift''' - A force exerted by the wind on an object. Lift is at right angles to the wind direction at the object. (see Drag)<br />
* '''Mold''' - A shaped container in which resin castings are formed. The mould can be discarded after the casting has set.<br />
* '''Multimeter''' - A versatile electrical test instrument, used to measure voltage, current and other parameters.<br />
* '''Neodymium''' - The name given to a type of permanent magnet containing neodymium, iron and boron. These magnets are very strong and <br />
getting cheaper all the time.<br />
* '''Offset''' - An eccentric position, off centre.<br />
* '''Talcum powder'''- A cheap filler powder used to thicken the resin and slow its reaction (prevent it overheating).<br />
* '''Tail''' - A projecting vane mounted on a boom at the back ofthe windmill used to steer it into or out of the wind automatically.<br />
* '''Tap''' - a tool for making thread inside holes so you can fit a screw into the hole.<br />
* '''Thrust''' - The force of the wind pushing the machine backwards.<br />
* '''Tower''' - The mast supporting the windmill.<br />
* '''Trailing edge''' - The blade edge furthest from the leading edge. The trailing edge is sharpened, so as to release the passing <br />
air without turbulence.<br />
* '''Wedges''' - Tapered pieces of wood used to build up the blade thickness and increase its angle to the wind near the root.<br />
* '''Work-piece''' - The piece of wood or metal being shaped in the workshop.<br />
* '''Yaw bearing''' - the swivel at the top of the tower on which the windmill is mounted. The yaw bearing allows the windmill to face the wind.<br />

=== The Foundry ===<br />
The Foundry is a non-profit organization based in a previously abandoned GaliZA village. It functions both as a residency and as a project space. It subscribes to the ideals of self-organization, and has the following three objectives:<br />
1. Organizing activities in the field of the arts, science and humanities outside of traditional institutions, focusing on critical discourse.<br />
2. Promoting the exchange of ideas and intellectual collaboration outside of the constraints imposed by state and market.<br />
3. Increasing self-sufficiency, sustainability, and an awareness of the environment using appropriate technology and open source as main resources.<br />
Taking into account this context, our aim is to reinforce the capacity to generate networks flowing from rural to urban context supporting non hierarchy and democratic exchanges of knowledge and practices that can enable new and sustainable models within rural contexts. According to that we consider that the new trans-disciplinary creative sectors in which we are entangled can have a huge and positive impact in the creation of this new paradigm. https://bravosfoundry.com/<br />
Aside from that, there is thematic focus on transdisciplinarity, transfeminism and post-humanism. While this focus is not adequately grasped by identity-political categories like race or gender, we hope it leads to the subversion of hegemonic structures inscribed in the binarisms upholding many of these categories. Our interest lies in the development of tools and technologies that subvert contemporary structures of domination, exploitation and marginalization, not in those that reproduce it.<br />
We seek to develop a more sustainable environment by opening up our practices based on a free culture framework, generating networks and interest around them, enabling a flow of exchange of innovation across creative sectors focusing on revaluation of rural contexts and its knowledge heritage.<br />

=== '''Section 2, involves the construction of '''the alternator''' parts using the devices from the section 1.''' ===<br />
<br />
'''Alternator'''<br />
Each magnet rotor is a steel disk with 12 magnets placed on it and set in resin. The magnets are each 50 x 50 x 20 mm, and they only just fit on the disk. The idea is to achieve the maximum amount of flux in a given space.<br />
The turbine runs at 650 rpm for 400W output, so the centrifugal force on the magnets is 60 times the force of gravity. To prevent them flying off, the resin casting needs to be reinforced. Stainless steel wire rope is placed around the outside of the magnets to hold the casting together at high rpm. We use stainless because it is non-magnetic, or at least less magnetic than normal steel wire rope. <br />
<br />
You will wind the coils that produce the output power and cast them in resin to form a stator between the two magnet rotors. Photos of the final pieces here <br />

<br />
[[File:prod05.jpg|300px]] <br />
<br />
Step - Generator, rotor: Preparation of the wheel hub.<br />
<br />
[[File:frame10.jpg|300px]]<br />
<br />
'''The wheel hub'''<br />
<br />
You can find a used car rear wheel hub (Golf, Toyota, etc.) that has a simple way to<br />
attach the axle, or alternatively buy a trailer hubs online new at low cost.<br />
PCD or ‘pitch circle diameter' is the diameter of the circle of the hole pattern in the<br />
hub, and usually this will be 100mm for a car wheel hub, or 4 inches for a trailer hub.<br />
Car hubs may have a brake-drum that you do not need. This can be removed using a<br />
cutting disk on a grinder. The simplest approach is to make four straight cuts around<br />
the four holes in the front, leaving a square surface to which you mount the magnet<br />
rotors. These photos show a golf rear wheel hub – first the brake-drum being cut, and<br />
then the finished hub after cutting off the drum.A typical rear wheel car hub with a <br />
flange on the back end of the stub shaft that can reused to mount it.<br />
Trailer hubs on the other hand are rather basic quality, and the bearings may be too<br />
cheap for long term use, but they are readily available items that can be purchased<br />
online as new. The drawings below (from autow.com) show a typical hub and stub<br />
axle which are bought separately.<br />
You need to be ready to replace the bearings with a named brand (such as SKF). It’s<br />
easy to replace the inner cones and rollers but the outer shells need to be knocked<br />
gently out of the hub with a suitable drift. Keep them straight by tapping evenly on<br />
opposite sides, and take care not to scratch the seating.<br />

=== Section 4, involves the craving of the blades and the welding of the base for the turbine generator. ===<br />
<br />
4.1 Making the blades <br />
The drawknife is useful for thicker chunks of wood, and for cutting down into a hollow. <br />
It can make a nice smooth job of the root of the blade, whereas the plane will work better <br />
where you need a very straight finish.<br />
<br />
'''Marking the stations.'''<br />
<br />
Place the blade with its best edge toward you on its upper surface. This will actually<br />
become the back or ‘downwind’ side of the finished blade.<br />
(Most of the front or windward side is to be cut off, so defects on this underneath side<br />
are not important.)<br />
<br />
The root of the blade will be on your right, the tip at the left, 1000 mm from the root<br />
(near the left end).<br />
<br />
Measure from the root, and mark four stations.<br />
Station A at 75mm<br />
Station B at 150 mm<br />
Station C at 500 mm<br />
The Tip at 1000 mm.<br />
<br />
<br />
At each station draw a line right around the workpiece using a square.<br />
<br />
[[File:01tur.jpeg|400px]]<br />
<br />
<br />
'''Tapering the blade'''<br />
The width of the blade tapers down from full size at station C to 55 mm wide at the<br />
tip. Mark the 55 mm tip width, measuring from the leading edge side. Draw a line<br />
though your mark to the trailing edge side at C station and cut off a triangular piece so<br />
as to achieve the correct tapered shape for the blade. Any knots in the triangular<br />
off cut do not matter as this piece is discarded. Try to make this a "square" cut,<br />
perpendicular to the back surface of the blade.<br />
You can do this with a circular saw, or by cross-cutting and shaving as described<br />
above.<br />
<br />
<br />
[[File:02tur.jpeg|400px]]<br />
<br />
'''Marking the leading and trailing edges'''<br />
The next step is to cut the windward face of the blade. This face is defined by the<br />
leading and trailing edge lines of the blade. These lines need to be marked with<br />
reference to the back face of the wood which has been uppermost in the previous<br />
operation.<br />
<br />
Turn the wood over. Start by drawing two diagonal lines between stations A and B<br />
on the front or windward side (see below). One is on the front face and the other on<br />
the trailing edge which is now toward you. <br />
<br />
[[File:03tur.jpeg|400px]]<br />
<br />
<br />
Now draw the leading edge line as shown below, <br />
from station B, down to 16mm(from the back) at station C, then continuing to the tip at<br />
7mm from the back.<br />
<br />
[[File:04tur.jpeg|400px]]<br />
<br />
<br />
(This drawing does not show the extra bit beyond the tip which may remain <br />
in your actual workpiece.)<br />
<br />
Measurements are summarised in this table below. Heights are from the back of the<br />
blade which will then rest on the bench. Remove the wood above this height. "Full"<br />
refers to the full thickness of the original piece of wood you are using.<br />
<br />
<br />
<br />
[[File:05tur.jpeg|400px]]<br />
<br />
<br />
'''The trailing''' <br />
The trailing edge line starts at the bottom of the diagonal line at station B, and <br />
rises to 5mm at C, continuing at 5 mm to the tip. This view below shows the wood <br />
already removed between the two lines to form the windward face of the blade.<br />
<br />
<br />
[[File:06tur.png|400px]]<br />
<br />
<br />
Carve this flat windward face between the 2 lines. Take care that the edges are<br />
straight, following the lines. The best tool to use for finishing the outer part of the<br />
blade is a plane, to give a smooth, straight finish. You may need to work the plane at<br />
45 degrees to the workpiece, sliding partly sideways, to form the hollow shape at<br />
station C.<br />
<br />
This step is completed when you can place a ruler across the face between the leading<br />
and trailing edge lines and there is no ‘hump’ in the middle. Fill any chips or small<br />
hollows with wood filler. If there are any serious errors, or large knots that weaken<br />
the blade then it may have to be discarded.<br />
Check the “drop” using a level as a reference. Clamp the wood so that the root part<br />
sits level, and measure the difference in level between the leading and trailing edges.<br />
The difference or “drop” should be 11 mm at the 500 mm mid-point, and 2 mm at the<br />
tip.<br />

<br />
O principal obxectivo deste evento é prototipar un xerador eólico a pequena escala para camiñar xuntos cara á autosuficiencia neste campo.<br />
Temos o pracer de comunicarvos que do 16 ao 23 de outubro Biotranslab de Pin e The Foundry establecen unha colaboración para levar a cabo o evento Eco (i) Logic Queer Energy harvesting. O proxecto é posible grazas ao apoio de GOSH, unha rede para desenvolver e difundir proxectos baseados en hardware de código aberto para a ciencia.<br />
<br />
EcoLoxicas Queer para a captación de enerxía eolica. <br />
O evento ten como obxectivo abordar a falta de mulleres, queer, trans e diversidade nos ámbitos tecnolóxicos en xeral e do hacking máis concretamente. Pero aínda máis, pretende crear unha comunidade que avalía criticamente as narrativas hexemónicas arredor das tecnoloxías, os aspectos de modernidade dos seus supostos occidentais subliñados e as súas inflexións capitalistas inherentes, entre outros.<br />
O obxectivo principal do evento é desenvolver kits que se centren na interacción co medio natural no ámbito da enerxía.. o obxectivo principal pasa pola captación de enerxía do medio natural, a través dos aeroxeradores. Estes kits de enerxía serán escalables e poderán utilizarse tanto como material pedagóxico como para instalar centrais eléctricas específicas do sitio en diferentes sitios tamén. Este traballo ten un compoñente contrainfraestrutural: unha posible consecuencia sería capacitar ás persoas para xerar a súa propia enerxía en lugar de depender de grandes empresas e moitas veces extractivas.<br />

''Pedagogies of the Wind and Stars. The social relations that we (were never meant to) survive, also live in our bodies painfully, and Audre Lorde is not here to remind us of this lesson herself, except in as much that she is present in the pedagogical wind. But wind is our teacher (74). -Alexis Pauline Gumbs'' from the book Mapping Queer Space(s) of Praxis and Pedagogy <br />

<br />
We have the pleasure to communicate you that from 16 to 29 of October Pin Biotranslab, Casa do Río e The Foundry establishes a collaboration to run the event Eco (i) Logic Queer Energy harvesting. The project is possible thanks to the support of GOSH, an network for develop and disseminate projects based on Open Source hardware for Science.<br />
<br />
'''Eco (i) Logic Queer Energy harvesting''' <br />
The event aims at addressing the lack of women, queer, trans and diversity in technological fields in general and hacking more specifically. But even more so, it aims at creating a community that critically assesses the hegemonic narratives around technologies, the modernity aspects of its underlining Western assumptions and its inherent capitalist inflections, among others.<br />
The main purpose of the event is to develop kits that focus on interacting with the natural environment on the field of energy.. the main objective lies on harvesting energy of the natural environment, through wind turbines. These power kits will be scalable and can be used both as pedagogical material and to set up site-specific power plants in different sites as well. There is a counter-infrastructural component to this work: one possible consequence would be to empower people to generate their own energy instead of relying on large and often extractive companies.<br />
<br />
== Introduction and values of the process ==<br />
<br />
Here starts the documentation of the long process of the prototyping the Hugh Piggott The Piggott Turbine – Wind Empowerment model of an Open source wind turbine. We were changing a bit the goals of the event from developing small kits to going to build the real 2m size wind turbine to provide energy to the rural regional areas we were working on. In that specific event we were working at The Foundry a nice project and association that we have settled on the north part of GaliZA into the Northwest of Spain.<br />
<br />
During the event many things have been activated between the doers and the visitors; In general It was a wondering experience full of new things to study, learn, doing and understand together. <br />
<br />
We chose this model because It was full of layers of interest on the levels of learning, understanding and making it, here some levels mixed up with layers: <br />
<br />
first to all is one of the ones that is '''open source''' or at least has the option to access the full documentation.<br />
<br />
really '''rich on the pedagogical level''', we were really learning through the complete building of the generator itself, about many topics as :<br />
* electromagnetism<br />
* mathematics<br />
* geometry<br />
* electronics<br />
* AC-DC<br />
* welding<br />
* wood carving<br />
* sculpting and casting pieces<br />
and much more that was reaching through the nice process of reading, learning and building together.<br />
<br />
== Glossary ==<br />
<br />
* '''AC-'''Alternating current as produced by the alternator. All thread - USA word for 'threaded' or 'spun' rod or studding<br />
* '''Brake switch''' - A switch used to short-circuit the wires from the alternator so that it stops.<br />
* '''Catalyst''' - A chemical used to make the polyester resin set solid. Catalyst reacts with 'accelerator' already present in the resin mix. <br />
The heat of reaction sets the polyester.<br />
* '''Cavalier''' - A make of car. The cavalier in the UK is not the same as the Cavalier in the USA but both have useful wheel hubs.<br />
* '''DC - direct current''' with a positive and a negative side, as in battery circuits.<br />
* '''Diameter''' - The distance from one side of a circle to another. The width of a disk right across the middle.<br />
* '''Phase''' - The timing of the cyclical alternation of voltage in a circuit. Different phases will peak at different times.<br />
* '''Polyester''' - A type of resin used in fibreglass work. Also suitable for making castings.<br />
* '''Power''' - the rate of delivery of energy<br />
* '''Rectifier''' - A semiconductor device that turns AC into DC for charging the battery.<br />
* '''Root''' - The widest part of the blade near to the hub at the center of the rotor.<br />
* '''Rotor''' - A rotating part. Magnet rotors are the steel diskscarrying the magnets past the stator. Rotor blades are the 'propeller' <br />
driven by the wind and driving the magnet rotors.<br />
* '''Soldering''' - A method for making electrical connections between wires using a hot 'iron' and coating everything with molten solder.<br />
* '''Drag''' - A force exerted by the wind on an object. Drag is parallel to the wind direction at the object. (see Lift) <br />
* '''Stator''' - An assembly of coils embedded in a slab of resin to form part of the alternator. The magnets induce a voltage in the coils and we can use this to charge a battery.<br />
* '''Drop''' - Used here to describe a certain measurement of the shape of a windmill blade. The 'drop' affects the angle of<br />
the blade to the wind. Styrene monomer - A nasty smelling solvent in the polyester resin mix.<br />
* '''Flux''' - The 'stuff' of magnetism. Similar to 'current' in electricity. It can be visualized as 'lines' coming out of one pole and <br />
returning to the other.<br />
* '''Furling''' - A protective action that reduces exposure to violent winds by facing the blades away from them.<br />
* '''Jig''' - A device used to hold the magnets in place before setting them in resin.<br />
* '''Leading edge''' - The edge of a blade that would strike an object placed in its path as the rotor spins.<br />
* '''Lift''' - A force exerted by the wind on an object. Lift is at right angles to the wind direction at the object. (see Drag)<br />
* '''Mold''' - A shaped container in which resin castings are formed. The mould can be discarded after the casting has set.<br />
* '''Multimeter''' - A versatile electrical test instrument, used to measure voltage, current and other parameters.<br />
* '''Neodymium''' - The name given to a type of permanent magnet containing neodymium, iron and boron. These magnets are very strong and <br />
getting cheaper all the time.<br />
* '''Offset''' - An eccentric position, off centre.<br />
* '''Talcum powder'''- A cheap filler powder used to thicken the resin and slow its reaction (prevent it overheating).<br />
* '''Tail''' - A projecting vane mounted on a boom at the back ofthe windmill used to steer it into or out of the wind automatically.<br />
* '''Tap''' - a tool for making thread inside holes so you can fit a screw into the hole.<br />
* '''Thrust''' - The force of the wind pushing the machine backwards.<br />
* '''Tower''' - The mast supporting the windmill.<br />
* '''Trailing edge''' - The blade edge furthest from the leading edge. The trailing edge is sharpened, so as to release the passing <br />
air without turbulence.<br />
* '''Wedges''' - Tapered pieces of wood used to build up the blade thickness and increase its angle to the wind near the root.<br />
* '''Work-piece''' - The piece of wood or metal being shaped in the workshop.<br />
* '''Yaw bearing''' - the swivel at the top of the tower on which the windmill is mounted. The yaw bearing allows the windmill to face the wind.<br />

=== The Foundry ===<br />
The Foundry is a non-profit organization based in a previously abandoned GaliZA village. It functions both as a residency and as a project space. It subscribes to the ideals of self-organization, and has the following three objectives:<br />
1. Organizing activities in the field of the arts, science and humanities outside of traditional institutions, focusing on critical discourse.<br />
2. Promoting the exchange of ideas and intellectual collaboration outside of the constraints imposed by state and market.<br />
3. Increasing self-sufficiency, sustainability, and an awareness of the environment using appropriate technology and open source as main resources.<br />
Taking into account this context, our aim is to reinforce the capacity to generate networks flowing from rural to urban context supporting non hierarchy and democratic exchanges of knowledge and practices that can enable new and sustainable models within rural contexts. According to that we consider that the new trans-disciplinary creative sectors in which we are entangled can have a huge and positive impact in the creation of this new paradigm. https://bravosfoundry.com/<br />
Aside from that, there is thematic focus on transdisciplinarity, transfeminism and post-humanism. While this focus is not adequately grasped by identity-political categories like race or gender, we hope it leads to the subversion of hegemonic structures inscribed in the binarisms upholding many of these categories. Our interest lies in the development of tools and technologies that subvert contemporary structures of domination, exploitation and marginalization, not in those that reproduce it.<br />
We seek to develop a more sustainable environment by opening up our practices based on a free culture framework, generating networks and interest around them, enabling a flow of exchange of innovation across creative sectors focusing on revaluation of rural contexts and its knowledge heritage.<br />

=== '''Section 2, involves the construction of '''the alternator''' parts using the devices from the section 1.''' ===<br />
<br />
'''Alternator'''<br />
Each magnet rotor is a steel disk with 12 magnets placed on it and set in resin. The magnets are each 50 x 50 x 20 mm, and they only just fit on the disk. The idea is to achieve the maximum amount of flux in a given space.<br />
The turbine runs at 650 rpm for 400W output, so the centrifugal force on the magnets is 60 times the force of gravity. To prevent them flying off, the resin casting needs to be reinforced. Stainless steel wire rope is placed around the outside of the magnets to hold the casting together at high rpm. We use stainless because it is non-magnetic, or at least less magnetic than normal steel wire rope. <br />
<br />
You will wind the coils that produce the output power and cast them in resin to form a stator between the two magnet rotors. Photos of the final pieces here <br />

Step - Generator, rotor: Preparation of the metallic disk. was made by machine at the shop <br />
<br />
[[File:prod05.jpg|400px]] <br />
<br />
Step - Generator, rotor: Preparation of the wheel hub.<br />
<br />
[[File:frame10.jpg|800px]]<br />
<br />
'''The wheel hub'''<br />
<br />
You can find a used car rear wheel hub (Golf, Toyota, etc.) that has a simple way to<br />
attach the axle, or alternatively buy a trailer hubs online new at low cost.<br />
PCD or ‘pitch circle diameter' is the diameter of the circle of the hole pattern in the<br />
hub, and usually this will be 100mm for a car wheel hub, or 4 inches for a trailer hub.<br />
Car hubs may have a brake-drum that you do not need. This can be removed using a<br />
cutting disk on a grinder. The simplest approach is to make four straight cuts around<br />
the four holes in the front, leaving a square surface to which you mount the magnet<br />
rotors. These photos show a golf rear wheel hub – first the brake-drum being cut, and<br />
then the finished hub after cutting off the drum.A typical rear wheel car hub with a <br />
flange on the back end of the stub shaft that can reused to mount it.<br />
Trailer hubs on the other hand are rather basic quality, and the bearings may be too<br />
cheap for long term use, but they are readily available items that can be purchased<br />
online as new. The drawings below (from autow.com) show a typical hub and stub<br />
axle which are bought separately.<br />
You need to be ready to replace the bearings with a named brand (such as SKF). It’s<br />
easy to replace the inner cones and rollers but the outer shells need to be knocked<br />
gently out of the hub with a suitable drift. Keep them straight by tapping evenly on<br />
opposite sides, and take care not to scratch the seating.<br />

=== Section 4, involves the craving of the blades and the welding of the base for the turbine generator. ===<br />
<br />
4.1 Making the blades <br />
The drawknife is useful for thicker chunks of wood, and for cutting down into a hollow. <br />
It can make a nice smooth job of the root of the blade, whereas the plane will work better <br />
where you need a very straight finish.<br />
<br />
'''Marking the stations.'''<br />
<br />
Place the blade with its best edge toward you on its upper surface. This will actually<br />
become the back or ‘downwind’ side of the finished blade.<br />
(Most of the front or windward side is to be cut off, so defects on this underneath side<br />
are not important.)<br />
<br />
The root of the blade will be on your right, the tip at the left, 1000 mm from the root<br />
(near the left end).<br />
<br />
Measure from the root, and mark four stations.<br />
Station A at 75mm<br />
Station B at 150 mm<br />
Station C at 500 mm<br />
The Tip at 1000 mm.<br />
<br />
<br />
At each station draw a line right around the workpiece using a square.<br />
<br />
[[File:01tur.jpeg|400px]]<br />
<br />
<br />
'''Tapering the blade'''<br />
The width of the blade tapers down from full size at station C to 55 mm wide at the<br />
tip. Mark the 55 mm tip width, measuring from the leading edge side. Draw a line<br />
though your mark to the trailing edge side at C station and cut off a triangular piece so<br />
as to achieve the correct tapered shape for the blade. Any knots in the triangular<br />
off cut do not matter as this piece is discarded. Try to make this a "square" cut,<br />
perpendicular to the back surface of the blade.<br />
You can do this with a circular saw, or by cross-cutting and shaving as described<br />
above.<br />
<br />
<br />
[[File:02tur.jpeg|400px]]<br />
<br />
'''Marking the leading and trailing edges'''<br />
The next step is to cut the windward face of the blade. This face is defined by the<br />
leading and trailing edge lines of the blade. These lines need to be marked with<br />
reference to the back face of the wood which has been uppermost in the previous<br />
operation.<br />
<br />
Turn the wood over. Start by drawing two diagonal lines between stations A and B<br />
on the front or windward side (see below). One is on the front face and the other on<br />
the trailing edge which is now toward you. <br />
<br />
[[File:03tur.jpeg|400px]]<br />
<br />
<br />
Now draw the leading edge line as shown below, <br />
from station B, down to 16mm(from the back) at station C, then continuing to the tip at<br />
7mm from the back.<br />
<br />
[[File:04tur.jpeg|400px]]<br />
<br />
<br />
(This drawing does not show the extra bit beyond the tip which may remain <br />
in your actual workpiece.)<br />
<br />
Measurements are summarised in this table below. Heights are from the back of the<br />
blade which will then rest on the bench. Remove the wood above this height. "Full"<br />
refers to the full thickness of the original piece of wood you are using.<br />
<br />
<br />
<br />
[[File:05tur.jpeg|400px]]<br />
<br />
<br />
'''The trailing''' <br />
The trailing edge line starts at the bottom of the diagonal line at station B, and <br />
rises to 5mm at C, continuing at 5 mm to the tip. This view below shows the wood <br />
already removed between the two lines to form the windward face of the blade.<br />
<br />
<br />
[[File:06tur.png|400px]]<br />
<br />
<br />
Carve this flat windward face between the 2 lines. Take care that the edges are<br />
straight, following the lines. The best tool to use for finishing the outer part of the<br />
blade is a plane, to give a smooth, straight finish. You may need to work the plane at<br />
45 degrees to the workpiece, sliding partly sideways, to form the hollow shape at<br />
station C.<br />
<br />
This step is completed when you can place a ruler across the face between the leading<br />
and trailing edge lines and there is no ‘hump’ in the middle. Fill any chips or small<br />
hollows with wood filler. If there are any serious errors, or large knots that weaken<br />
the blade then it may have to be discarded.<br />
Check the “drop” using a level as a reference. Clamp the wood so that the root part<br />
sits level, and measure the difference in level between the leading and trailing edges.<br />
The difference or “drop” should be 11 mm at the 500 mm mid-point, and 2 mm at the<br />
tip.<br />

<br />
O principal obxectivo deste evento é prototipar un xerador eólico a pequena escala para camiñar xuntos cara á autosuficiencia neste campo.<br />
Temos o pracer de comunicarvos que do 16 ao 23 de outubro Biotranslab de Pin e The Foundry establecen unha colaboración para levar a cabo o evento Eco (i) Logic Queer Energy harvesting. O proxecto é posible grazas ao apoio de GOSH, unha rede para desenvolver e difundir proxectos baseados en hardware de código aberto para a ciencia.<br />
<br />
EcoLoxicas Queer para a captación de enerxía eolica. <br />
O evento ten como obxectivo abordar a falta de mulleres, queer, trans e diversidade nos ámbitos tecnolóxicos en xeral e do hacking máis concretamente. Pero aínda máis, pretende crear unha comunidade que avalía criticamente as narrativas hexemónicas arredor das tecnoloxías, os aspectos de modernidade dos seus supostos occidentais subliñados e as súas inflexións capitalistas inherentes, entre outros.<br />
O obxectivo principal do evento é desenvolver kits que se centren na interacción co medio natural no ámbito da enerxía.. o obxectivo principal pasa pola captación de enerxía do medio natural, a través dos aeroxeradores. Estes kits de enerxía serán escalables e poderán utilizarse tanto como material pedagóxico como para instalar centrais eléctricas específicas do sitio en diferentes sitios tamén. Este traballo ten un compoñente contrainfraestrutural: unha posible consecuencia sería capacitar ás persoas para xerar a súa propia enerxía en lugar de depender de grandes empresas e moitas veces extractivas.<br />

''Pedagogies of the Wind and Stars. The social relations that we (were never meant to) survive, also live in our bodies painfully, and Audre Lorde is not here to remind us of this lesson herself, except in as much that she is present in the pedagogical wind. But wind is our teacher (74). -Alexis Pauline Gumbs'' from the book Mapping Queer Space(s) of Praxis and Pedagogy <br />
Editors: Elizabeth McNeil, James E. Wermers, Joshua O. Lunn'' <br />
<br />
We have the pleasure to communicate you that from 16 to 29 of October Pin Biotranslab, Casa do Río e The Foundry establishes a collaboration to run the event Eco (i) Logic Queer Energy harvesting. The project is possible thanks to the support of GOSH, an network for develop and disseminate projects based on Open Source hardware for Science.<br />
<br />
'''Eco (i) Logic Queer Energy harvesting''' <br />
The event aims at addressing the lack of women, queer, trans and diversity in technological fields in general and hacking more specifically. But even more so, it aims at creating a community that critically assesses the hegemonic narratives around technologies, the modernity aspects of its underlining Western assumptions and its inherent capitalist inflections, among others.<br />
The main purpose of the event is to develop kits that focus on interacting with the natural environment on the field of energy.. the main objective lies on harvesting energy of the natural environment, through wind turbines. These power kits will be scalable and can be used both as pedagogical material and to set up site-specific power plants in different sites as well. There is a counter-infrastructural component to this work: one possible consequence would be to empower people to generate their own energy instead of relying on large and often extractive companies.<br />
<br />
== Introduction and values of the process ==<br />
<br />
Here starts the documentation of the long process of the prototyping the Hugh Piggott The Piggott Turbine – Wind Empowerment model of an Open source wind turbine. We were changing a bit the goals of the event from developing small kits to going to build the real 2m size wind turbine to provide energy to the rural regional areas we were working on. In that specific event we were working at The Foundry a nice project and association that we have settled on the north part of GaliZA into the Northwest of Spain.<br />
<br />
During the event many things have been activated between the doers and the visitors; In general It was a wondering experience full of new things to study, learn, doing and understand together. <br />
<br />
We chose this model because It was full of layers of interest on the levels of learning, understanding and making it, here some levels mixed up with layers: <br />
<br />
first to all is one of the ones that is '''open source''' or at least has the option to access the full documentation.<br />
<br />
really '''rich on the pedagogical level''', we were really learning through the complete building of the generator itself, about many topics as :<br />
* electromagnetism<br />
* mathematics<br />
* geometry<br />
* electronics<br />
* AC-DC<br />
* welding<br />
* wood carving<br />
* sculpting and casting pieces<br />
and much more that was reaching through the nice process of reading, learning and building together.<br />
<br />
== Glossary ==<br />
<br />
* '''AC-'''Alternating current as produced by the alternator. All thread - USA word for 'threaded' or 'spun' rod or studding<br />
* '''Brake switch''' - A switch used to short-circuit the wires from the alternator so that it stops.<br />
* '''Catalyst''' - A chemical used to make the polyester resin set solid. Catalyst reacts with 'accelerator' already present in the resin mix. <br />
The heat of reaction sets the polyester.<br />
* '''Cavalier''' - A make of car. The cavalier in the UK is not the same as the Cavalier in the USA but both have useful wheel hubs.<br />
* '''DC - direct current''' with a positive and a negative side, as in battery circuits.<br />
* '''Diameter''' - The distance from one side of a circle to another. The width of a disk right across the middle.<br />
* '''Phase''' - The timing of the cyclical alternation of voltage in a circuit. Different phases will peak at different times.<br />
* '''Polyester''' - A type of resin used in fibreglass work. Also suitable for making castings.<br />
* '''Power''' - the rate of delivery of energy<br />
* '''Rectifier''' - A semiconductor device that turns AC into DC for charging the battery.<br />
* '''Root''' - The widest part of the blade near to the hub at the center of the rotor.<br />
* '''Rotor''' - A rotating part. Magnet rotors are the steel diskscarrying the magnets past the stator. Rotor blades are the 'propeller' <br />
driven by the wind and driving the magnet rotors.<br />
* '''Soldering''' - A method for making electrical connections between wires using a hot 'iron' and coating everything with molten solder.<br />
* '''Drag''' - A force exerted by the wind on an object. Drag is parallel to the wind direction at the object. (see Lift) <br />
* '''Stator''' - An assembly of coils embedded in a slab of resin to form part of the alternator. The magnets induce a voltage in the coils and we can use this to charge a battery.<br />
* '''Drop''' - Used here to describe a certain measurement of the shape of a windmill blade. The 'drop' affects the angle of<br />
the blade to the wind. Styrene monomer - A nasty smelling solvent in the polyester resin mix.<br />
* '''Flux''' - The 'stuff' of magnetism. Similar to 'current' in electricity. It can be visualized as 'lines' coming out of one pole and <br />
returning to the other.<br />
* '''Furling''' - A protective action that reduces exposure to violent winds by facing the blades away from them.<br />
* '''Jig''' - A device used to hold the magnets in place before setting them in resin.<br />
* '''Leading edge''' - The edge of a blade that would strike an object placed in its path as the rotor spins.<br />
* '''Lift''' - A force exerted by the wind on an object. Lift is at right angles to the wind direction at the object. (see Drag)<br />
* '''Mold''' - A shaped container in which resin castings are formed. The mould can be discarded after the casting has set.<br />
* '''Multimeter''' - A versatile electrical test instrument, used to measure voltage, current and other parameters.<br />
* '''Neodymium''' - The name given to a type of permanent magnet containing neodymium, iron and boron. These magnets are very strong and <br />
getting cheaper all the time.<br />
* '''Offset''' - An eccentric position, off centre.<br />
* '''Talcum powder'''- A cheap filler powder used to thicken the resin and slow its reaction (prevent it overheating).<br />
* '''Tail''' - A projecting vane mounted on a boom at the back ofthe windmill used to steer it into or out of the wind automatically.<br />
* '''Tap''' - a tool for making thread inside holes so you can fit a screw into the hole.<br />
* '''Thrust''' - The force of the wind pushing the machine backwards.<br />
* '''Tower''' - The mast supporting the windmill.<br />
* '''Trailing edge''' - The blade edge furthest from the leading edge. The trailing edge is sharpened, so as to release the passing <br />
air without turbulence.<br />
* '''Wedges''' - Tapered pieces of wood used to build up the blade thickness and increase its angle to the wind near the root.<br />
* '''Work-piece''' - The piece of wood or metal being shaped in the workshop.<br />
* '''Yaw bearing''' - the swivel at the top of the tower on which the windmill is mounted. The yaw bearing allows the windmill to face the wind.<br />

The Foundry is a non-profit organization based in a previously abandoned GaliZA village. It functions both as a residency and as a project space. It subscribes to the ideals of self-organization, and has the following three objectives:<br />

2. Promoting the exchange of ideas and intellectual collaboration outside of the constraints imposed by state and market.<br />
3. Increasing self-sufficiency, sustainability, and an awareness of the environment using appropriate technology and open source as main resources.<br />
Taking into account this context, our aim is to reinforce the capacity to generate networks flowing from rural to urban context supporting non hierarchy and democratic exchanges of knowledge and practices that can enable new and sustainable models within rural contexts. According to that we consider that the new trans-disciplinary creative sectors in which we are entangled can have a huge and positive impact in the creation of this new paradigm. https://bravosfoundry.com/<br />
Aside from that, there is thematic focus on transdisciplinarity, transfeminism and post-humanism. While this focus is not adequately grasped by identity-political categories like race or gender, we hope it leads to the subversion of hegemonic structures inscribed in the binarisms upholding many of these categories. Our interest lies in the development of tools and technologies that subvert contemporary structures of domination, exploitation and marginalization, not in those that reproduce it.<br />
We seek to develop a more sustainable environment by opening up our practices based on a free culture framework, generating networks and interest around them, enabling a flow of exchange of innovation across creative sectors focusing on revaluation of rural contexts and its knowledge heritage.<br />

=== '''Section 2, involves the construction of '''the alternator''' parts using the devices from the section 1.''' ===<br />
<br />
'''Alternator'''<br />
Each magnet rotor is a steel disk with 12 magnets placed on it and set in resin. The magnets are each 50 x 50 x 20 mm, and they only just fit on the disk. The idea is to achieve the maximum amount of flux in a given space.<br />
The turbine runs at 650 rpm for 400W output, so the centrifugal force on the magnets is 60 times the force of gravity. To prevent them flying off, the resin casting needs to be reinforced. Stainless steel wire rope is placed around the outside of the magnets to hold the casting together at high rpm. We use stainless because it is non-magnetic, or at least less magnetic than normal steel wire rope. <br />
<br />
You will wind the coils that produce the output power and cast them in resin to form a stator between the two magnet rotors. Photos of the final pieces here <br />

<br />
Step - Generator, rotor: Preparation of the wheel hub.<br />
<br />
[[File:frame10.jpg|800px]]<br />
<br />
'''The wheel hub'''<br />
<br />
You can find a used car rear wheel hub (Golf, Toyota, etc.) that has a simple way to<br />
attach the axle, or alternatively buy a trailer hubs online new at low cost.<br />
PCD or ‘pitch circle diameter' is the diameter of the circle of the hole pattern in the<br />
hub, and usually this will be 100mm for a car wheel hub, or 4 inches for a trailer hub.<br />
Car hubs may have a brake-drum that you do not need. This can be removed using a<br />
cutting disk on a grinder. The simplest approach is to make four straight cuts around<br />
the four holes in the front, leaving a square surface to which you mount the magnet<br />
rotors. These photos show a golf rear wheel hub – first the brake-drum being cut, and<br />
then the finished hub after cutting off the drum.A typical rear wheel car hub with a <br />
flange on the back end of the stub shaft that can reused to mount it.<br />
Trailer hubs on the other hand are rather basic quality, and the bearings may be too<br />
cheap for long term use, but they are readily available items that can be purchased<br />
online as new. The drawings below (from autow.com) show a typical hub and stub<br />
axle which are bought separately.<br />
You need to be ready to replace the bearings with a named brand (such as SKF). It’s<br />
easy to replace the inner cones and rollers but the outer shells need to be knocked<br />
gently out of the hub with a suitable drift. Keep them straight by tapping evenly on<br />
opposite sides, and take care not to scratch the seating.<br />

=== Section 4, involves the craving of the blades and the welding of the base for the turbine generator. ===<br />
<br />
4.1 Making the blades <br />
The drawknife is useful for thicker chunks of wood, and for cutting down into a hollow. <br />
It can make a nice smooth job of the root of the blade, whereas the plane will work better <br />
where you need a very straight finish.<br />
<br />
'''Marking the stations.'''<br />
<br />
Place the blade with its best edge toward you on its upper surface. This will actually<br />
become the back or ‘downwind’ side of the finished blade.<br />
(Most of the front or windward side is to be cut off, so defects on this underneath side<br />
are not important.)<br />
<br />
The root of the blade will be on your right, the tip at the left, 1000 mm from the root<br />
(near the left end).<br />
<br />
Measure from the root, and mark four stations.<br />
Station A at 75mm<br />
Station B at 150 mm<br />
Station C at 500 mm<br />
The Tip at 1000 mm.<br />
<br />
<br />
At each station draw a line right around the workpiece using a square.<br />
<br />
[[File:01tur.jpeg|400px]]<br />
<br />
<br />
'''Tapering the blade'''<br />
The width of the blade tapers down from full size at station C to 55 mm wide at the<br />
tip. Mark the 55 mm tip width, measuring from the leading edge side. Draw a line<br />
though your mark to the trailing edge side at C station and cut off a triangular piece so<br />
as to achieve the correct tapered shape for the blade. Any knots in the triangular<br />
off cut do not matter as this piece is discarded. Try to make this a "square" cut,<br />
perpendicular to the back surface of the blade.<br />
You can do this with a circular saw, or by cross-cutting and shaving as described<br />
above.<br />
<br />
<br />
[[File:02tur.jpeg|400px]]<br />
<br />
'''Marking the leading and trailing edges'''<br />
The next step is to cut the windward face of the blade. This face is defined by the<br />
leading and trailing edge lines of the blade. These lines need to be marked with<br />
reference to the back face of the wood which has been uppermost in the previous<br />
operation.<br />
<br />
Turn the wood over. Start by drawing two diagonal lines between stations A and B<br />
on the front or windward side (see below). One is on the front face and the other on<br />
the trailing edge which is now toward you. <br />
<br />
[[File:03tur.jpeg|400px]]<br />
<br />
<br />
Now draw the leading edge line as shown below, <br />
from station B, down to 16mm(from the back) at station C, then continuing to the tip at<br />
7mm from the back.<br />
<br />
[[File:04tur.jpeg|400px]]<br />
<br />
<br />
(This drawing does not show the extra bit beyond the tip which may remain <br />
in your actual workpiece.)<br />
<br />
Measurements are summarised in this table below. Heights are from the back of the<br />
blade which will then rest on the bench. Remove the wood above this height. "Full"<br />
refers to the full thickness of the original piece of wood you are using.<br />
<br />
<br />
<br />
[[File:05tur.jpeg|400px]]<br />
<br />
<br />
'''The trailing''' <br />
The trailing edge line starts at the bottom of the diagonal line at station B, and <br />
rises to 5mm at C, continuing at 5 mm to the tip. This view below shows the wood <br />
already removed between the two lines to form the windward face of the blade.<br />
<br />
<br />
[[File:06tur.png|400px]]<br />
<br />
<br />
Carve this flat windward face between the 2 lines. Take care that the edges are<br />
straight, following the lines. The best tool to use for finishing the outer part of the<br />
blade is a plane, to give a smooth, straight finish. You may need to work the plane at<br />
45 degrees to the workpiece, sliding partly sideways, to form the hollow shape at<br />
station C.<br />
<br />
This step is completed when you can place a ruler across the face between the leading<br />
and trailing edge lines and there is no ‘hump’ in the middle. Fill any chips or small<br />
hollows with wood filler. If there are any serious errors, or large knots that weaken<br />
the blade then it may have to be discarded.<br />
Check the “drop” using a level as a reference. Clamp the wood so that the root part<br />
sits level, and measure the difference in level between the leading and trailing edges.<br />
The difference or “drop” should be 11 mm at the 500 mm mid-point, and 2 mm at the<br />
tip.<br />

"Pedagoxías do vento e das estrelas. As relacións sociais ás que (nunca estabamos destinados a) sobrevivir, tamén vivimos nos nosos corpos dolorosamente, e Audre Lorde non está aquí para lembrarnos esta lección, salvo na medida en que está presente no vento pedagóxico.<br />
Pero o vento é o noso mestre (74). -Alexis Pauline Gumbs "<br />
<br />
O principal obxectivo deste evento é prototipar un xerador eólico a pequena escala para camiñar xuntos cara á autosuficiencia neste campo.<br />
Temos o pracer de comunicarvos que do 16 ao 23 de outubro Biotranslab de Pin e The Foundry establecen unha colaboración para levar a cabo o evento Eco (i) Logic Queer Energy harvesting. O proxecto é posible grazas ao apoio de GOSH, unha rede para desenvolver e difundir proxectos baseados en hardware de código aberto para a ciencia.<br />
<br />
EcoLoxicas Queer para a captación de enerxía eolica. <br />
O evento ten como obxectivo abordar a falta de mulleres, queer, trans e diversidade nos ámbitos tecnolóxicos en xeral e do hacking máis concretamente. Pero aínda máis, pretende crear unha comunidade que avalía criticamente as narrativas hexemónicas arredor das tecnoloxías, os aspectos de modernidade dos seus supostos occidentais subliñados e as súas inflexións capitalistas inherentes, entre outros.<br />
O obxectivo principal do evento é desenvolver kits que se centren na interacción co medio natural no ámbito da enerxía.. o obxectivo principal pasa pola captación de enerxía do medio natural, a través dos aeroxeradores. Estes kits de enerxía serán escalables e poderán utilizarse tanto como material pedagóxico como para instalar centrais eléctricas específicas do sitio en diferentes sitios tamén. Este traballo ten un compoñente contrainfraestrutural: unha posible consecuencia sería capacitar ás persoas para xerar a súa propia enerxía en lugar de depender de grandes empresas e moitas veces extractivas.<br />

''Pedagogies of the Wind and Stars. The social relations that we (were never meant to) survive, also live in our bodies painfully, and Audre Lorde is not here to remind us of this lesson herself, except in as much that she is present in the pedagogical wind. But wind is our teacher (74). -Alexis Pauline Gumbs'' from the book Mapping Queer Space(s) of Praxis and Pedagogy <br />
Editors: Elizabeth McNeil, James E. Wermers, Joshua O. Lunn'' <br />
<br />
We have the pleasure to communicate you that from 16 to 29 of October Pin Biotranslab, Casa do Río e The Foundry establishes a collaboration to run the event Eco (i) Logic Queer Energy harvesting. The project is possible thanks to the support of GOSH, an network for develop and disseminate projects based on Open Source hardware for Science.<br />
<br />
'''Eco (i) Logic Queer Energy harvesting''' <br />
The event aims at addressing the lack of women, queer, trans and diversity in technological fields in general and hacking more specifically. But even more so, it aims at creating a community that critically assesses the hegemonic narratives around technologies, the modernity aspects of its underlining Western assumptions and its inherent capitalist inflections, among others.<br />
The main purpose of the event is to develop kits that focus on interacting with the natural environment on the field of energy.. the main objective lies on harvesting energy of the natural environment, through wind turbines. These power kits will be scalable and can be used both as pedagogical material and to set up site-specific power plants in different sites as well. There is a counter-infrastructural component to this work: one possible consequence would be to empower people to generate their own energy instead of relying on large and often extractive companies.<br />
<br />
== Introduction and values of the process ==<br />
<br />
Here starts the documentation of the long process of the prototyping the Hugh Piggott The Piggott Turbine – Wind Empowerment model of an Open source wind turbine. We were changing a bit the goals of the event from developing small kits to going to build the real 2m size wind turbine to provide energy to the rural regional areas we were working on. In that specific event we were working at The Foundry a nice project and association that we have settled on the north part of GaliZA into the Northwest of Spain.<br />
<br />
During the event many things have been activated between the doers and the visitors; In general It was a wondering experience full of new things to study, learn, doing and understand together. <br />
<br />
We chose this model because It was full of layers of interest on the levels of learning, understanding and making it, here some levels mixed up with layers: <br />
<br />
first to all is one of the ones that is '''open source''' or at least has the option to access the full documentation.<br />
<br />
really '''rich on the pedagogical level''', we were really learning through the complete building of the generator itself, about many topics as :<br />
* electromagnetism<br />
* mathematics<br />
* geometry<br />
* electronics<br />
* AC-DC<br />
* welding<br />
* wood carving<br />
* sculpting and casting pieces<br />
and much more that was reaching through the nice process of reading, learning and building together.<br />
<br />
== Glossary ==<br />
<br />
* '''AC-'''Alternating current as produced by the alternator. All thread - USA word for 'threaded' or 'spun' rod or studding<br />
* '''Brake switch''' - A switch used to short-circuit the wires from the alternator so that it stops.<br />
* '''Catalyst''' - A chemical used to make the polyester resin set solid. Catalyst reacts with 'accelerator' already present in the resin mix. <br />
The heat of reaction sets the polyester.<br />
* '''Cavalier''' - A make of car. The cavalier in the UK is not the same as the Cavalier in the USA but both have useful wheel hubs.<br />
* '''DC - direct current''' with a positive and a negative side, as in battery circuits.<br />
* '''Diameter''' - The distance from one side of a circle to another. The width of a disk right across the middle.<br />
* '''Phase''' - The timing of the cyclical alternation of voltage in a circuit. Different phases will peak at different times.<br />
* '''Polyester''' - A type of resin used in fibreglass work. Also suitable for making castings.<br />
* '''Power''' - the rate of delivery of energy<br />
* '''Rectifier''' - A semiconductor device that turns AC into DC for charging the battery.<br />
* '''Root''' - The widest part of the blade near to the hub at the center of the rotor.<br />
* '''Rotor''' - A rotating part. Magnet rotors are the steel diskscarrying the magnets past the stator. Rotor blades are the 'propeller' <br />
driven by the wind and driving the magnet rotors.<br />
* '''Soldering''' - A method for making electrical connections between wires using a hot 'iron' and coating everything with molten solder.<br />
* '''Drag''' - A force exerted by the wind on an object. Drag is parallel to the wind direction at the object. (see Lift) <br />
* '''Stator''' - An assembly of coils embedded in a slab of resin to form part of the alternator. The magnets induce a voltage in the coils and we can use this to charge a battery.<br />
* '''Drop''' - Used here to describe a certain measurement of the shape of a windmill blade. The 'drop' affects the angle of<br />
the blade to the wind. Styrene monomer - A nasty smelling solvent in the polyester resin mix.<br />
* '''Flux''' - The 'stuff' of magnetism. Similar to 'current' in electricity. It can be visualized as 'lines' coming out of one pole and <br />
returning to the other.<br />
* '''Furling''' - A protective action that reduces exposure to violent winds by facing the blades away from them.<br />
* '''Jig''' - A device used to hold the magnets in place before setting them in resin.<br />
* '''Leading edge''' - The edge of a blade that would strike an object placed in its path as the rotor spins.<br />
* '''Lift''' - A force exerted by the wind on an object. Lift is at right angles to the wind direction at the object. (see Drag)<br />
* '''Mold''' - A shaped container in which resin castings are formed. The mould can be discarded after the casting has set.<br />
* '''Multimeter''' - A versatile electrical test instrument, used to measure voltage, current and other parameters.<br />
* '''Neodymium''' - The name given to a type of permanent magnet containing neodymium, iron and boron. These magnets are very strong and <br />
getting cheaper all the time.<br />
* '''Offset''' - An eccentric position, off centre.<br />
* '''Talcum powder'''- A cheap filler powder used to thicken the resin and slow its reaction (prevent it overheating).<br />
* '''Tail''' - A projecting vane mounted on a boom at the back ofthe windmill used to steer it into or out of the wind automatically.<br />
* '''Tap''' - a tool for making thread inside holes so you can fit a screw into the hole.<br />
* '''Thrust''' - The force of the wind pushing the machine backwards.<br />
* '''Tower''' - The mast supporting the windmill.<br />
* '''Trailing edge''' - The blade edge furthest from the leading edge. The trailing edge is sharpened, so as to release the passing <br />
air without turbulence.<br />
* '''Wedges''' - Tapered pieces of wood used to build up the blade thickness and increase its angle to the wind near the root.<br />
* '''Work-piece''' - The piece of wood or metal being shaped in the workshop.<br />
* '''Yaw bearing''' - the swivel at the top of the tower on which the windmill is mounted. The yaw bearing allows the windmill to face the wind.<br />

=== The Foundry ===<br />
The Foundry is a non-profit organization based in a previously abandoned GaliZA village. It functions both as a residency and as a project space. It subscribes to the ideals of self-organization, and has the following three objectives:<br />
1. Organizing activities in the field of the arts, science and humanities outside of traditional institutions, focusing on critical discourse.<br />
2. Promoting the exchange of ideas and intellectual collaboration outside of the constraints imposed by state and market.<br />
3. Increasing self-sufficiency, sustainability, and an awareness of the environment using appropriate technology and open source as main resources.<br />
Taking into account this context, our aim is to reinforce the capacity to generate networks flowing from rural to urban context supporting non hierarchy and democratic exchanges of knowledge and practices that can enable new and sustainable models within rural contexts. According to that we consider that the new trans-disciplinary creative sectors in which we are entangled can have a huge and positive impact in the creation of this new paradigm. https://bravosfoundry.com/<br />
Aside from that, there is thematic focus on transdisciplinarity, transfeminism and post-humanism. While this focus is not adequately grasped by identity-political categories like race or gender, we hope it leads to the subversion of hegemonic structures inscribed in the binarisms upholding many of these categories. Our interest lies in the development of tools and technologies that subvert contemporary structures of domination, exploitation and marginalization, not in those that reproduce it.<br />
We seek to develop a more sustainable environment by opening up our practices based on a free culture framework, generating networks and interest around them, enabling a flow of exchange of innovation across creative sectors focusing on revaluation of rural contexts and its knowledge heritage.<br />

Because of the complexity involved on the realization of the full assembly of the wind turbine we were thinking to divide the documentation in 4 different sections.<br />
<br />

=== '''Section 2, involves the construction of '''the alternator''' parts using the devices from the section 1.''' ===<br />
<br />
'''Alternator'''<br />
Each magnet rotor is a steel disk with 12 magnets placed on it and set in resin. The magnets are each 50 x 50 x 20 mm, and they only just fit on the disk. The idea is to achieve the maximum amount of flux in a given space.<br />
The turbine runs at 650 rpm for 400W output, so the centrifugal force on the magnets is 60 times the force of gravity. To prevent them flying off, the resin casting needs to be reinforced. Stainless steel wire rope is placed around the outside of the magnets to hold the casting together at high rpm. We use stainless because it is non-magnetic, or at least less magnetic than normal steel wire rope. <br />
<br />
You will wind the coils that produce the output power and cast them in resin to form a stator between the two magnet rotors. Photos of the final pieces here <br />

Step - Generator, rotor: Preparation of the wheel hub.<br />
<br />
[[File:frame10.jpg|800px]]<br />
<br />
'''The wheel hub'''<br />
<br />
You can find a used car rear wheel hub (Golf, Toyota, etc.) that has a simple way to<br />
attach the axle, or alternatively buy a trailer hubs online new at low cost.<br />
PCD or ‘pitch circle diameter' is the diameter of the circle of the hole pattern in the<br />
hub, and usually this will be 100mm for a car wheel hub, or 4 inches for a trailer hub.<br />
Car hubs may have a brake-drum that you do not need. This can be removed using a<br />
cutting disk on a grinder. The simplest approach is to make four straight cuts around<br />
the four holes in the front, leaving a square surface to which you mount the magnet<br />
rotors. These photos show a golf rear wheel hub – first the brake-drum being cut, and<br />
then the finished hub after cutting off the drum.A typical rear wheel car hub with a <br />
flange on the back end of the stub shaft that can reused to mount it.<br />
Trailer hubs on the other hand are rather basic quality, and the bearings may be too<br />
cheap for long term use, but they are readily available items that can be purchased<br />
online as new. The drawings below (from autow.com) show a typical hub and stub<br />
axle which are bought separately.<br />
You need to be ready to replace the bearings with a named brand (such as SKF). It’s<br />
easy to replace the inner cones and rollers but the outer shells need to be knocked<br />
gently out of the hub with a suitable drift. Keep them straight by tapping evenly on<br />
opposite sides, and take care not to scratch the seating.<br />

=== Section 4, involves the craving of the blades and the welding of the base for the turbine generator. ===<br />
<br />
4.1 Making the blades <br />
The drawknife is useful for thicker chunks of wood, and for cutting down into a hollow. <br />
It can make a nice smooth job of the root of the blade, whereas the plane will work better <br />
where you need a very straight finish.<br />
<br />
'''Marking the stations.'''<br />
<br />
Place the blade with its best edge toward you on its upper surface. This will actually<br />
become the back or ‘downwind’ side of the finished blade.<br />
(Most of the front or windward side is to be cut off, so defects on this underneath side<br />
are not important.)<br />
<br />
The root of the blade will be on your right, the tip at the left, 1000 mm from the root<br />
(near the left end).<br />
<br />
Measure from the root, and mark four stations.<br />
Station A at 75mm<br />
Station B at 150 mm<br />
Station C at 500 mm<br />
The Tip at 1000 mm.<br />
<br />
<br />
At each station draw a line right around the workpiece using a square.<br />
<br />
[[File:01tur.jpeg|400px]]<br />
<br />
<br />
'''Tapering the blade'''<br />
The width of the blade tapers down from full size at station C to 55 mm wide at the<br />
tip. Mark the 55 mm tip width, measuring from the leading edge side. Draw a line<br />
though your mark to the trailing edge side at C station and cut off a triangular piece so<br />
as to achieve the correct tapered shape for the blade. Any knots in the triangular<br />
off cut do not matter as this piece is discarded. Try to make this a "square" cut,<br />
perpendicular to the back surface of the blade.<br />
You can do this with a circular saw, or by cross-cutting and shaving as described<br />
above.<br />
<br />
<br />
[[File:02tur.jpeg|400px]]<br />
<br />
'''Marking the leading and trailing edges'''<br />
The next step is to cut the windward face of the blade. This face is defined by the<br />
leading and trailing edge lines of the blade. These lines need to be marked with<br />
reference to the back face of the wood which has been uppermost in the previous<br />
operation.<br />
<br />
Turn the wood over. Start by drawing two diagonal lines between stations A and B<br />
on the front or windward side (see below). One is on the front face and the other on<br />
the trailing edge which is now toward you. <br />
<br />
[[File:03tur.jpeg|400px]]<br />
<br />
<br />
Now draw the leading edge line as shown below, <br />
from station B, down to 16mm(from the back) at station C, then continuing to the tip at<br />
7mm from the back.<br />
<br />
[[File:04tur.jpeg|400px]]<br />
<br />
<br />
(This drawing does not show the extra bit beyond the tip which may remain <br />
in your actual workpiece.)<br />
<br />
Measurements are summarised in this table below. Heights are from the back of the<br />
blade which will then rest on the bench. Remove the wood above this height. "Full"<br />
refers to the full thickness of the original piece of wood you are using.<br />
<br />
<br />
<br />
[[File:05tur.jpeg|400px]]<br />
<br />
<br />
'''The trailing''' <br />
The trailing edge line starts at the bottom of the diagonal line at station B, and <br />
rises to 5mm at C, continuing at 5 mm to the tip. This view below shows the wood <br />
already removed between the two lines to form the windward face of the blade.<br />
<br />
<br />
[[File:06tur.png|400px]]<br />
<br />
<br />
Carve this flat windward face between the 2 lines. Take care that the edges are<br />
straight, following the lines. The best tool to use for finishing the outer part of the<br />
blade is a plane, to give a smooth, straight finish. You may need to work the plane at<br />
45 degrees to the workpiece, sliding partly sideways, to form the hollow shape at<br />
station C.<br />
<br />
This step is completed when you can place a ruler across the face between the leading<br />
and trailing edge lines and there is no ‘hump’ in the middle. Fill any chips or small<br />
hollows with wood filler. If there are any serious errors, or large knots that weaken<br />
the blade then it may have to be discarded.<br />
Check the “drop” using a level as a reference. Clamp the wood so that the root part<br />
sits level, and measure the difference in level between the leading and trailing edges.<br />
The difference or “drop” should be 11 mm at the 500 mm mid-point, and 2 mm at the<br />
tip.<br />

"Pedagoxías do vento e das estrelas. As relacións sociais ás que (nunca estabamos destinados a) sobrevivir, tamén vivimos nos nosos corpos dolorosamente, e Audre Lorde non está aquí para lembrarnos esta lección, salvo na medida en que está presente no vento pedagóxico.<br />
Pero o vento é o noso mestre (74). -Alexis Pauline Gumbs "<br />
<br />
O principal obxectivo deste evento é prototipar un xerador eólico a pequena escala para camiñar xuntos cara á autosuficiencia neste campo.<br />
Temos o pracer de comunicarvos que do 16 ao 23 de outubro Biotranslab de Pin e The Foundry establecen unha colaboración para levar a cabo o evento Eco (i) Logic Queer Energy harvesting. O proxecto é posible grazas ao apoio de GOSH, unha rede para desenvolver e difundir proxectos baseados en hardware de código aberto para a ciencia.<br />
<br />
EcoLoxicas Queer para a captación de enerxía eolica. <br />
O evento ten como obxectivo abordar a falta de mulleres, queer, trans e diversidade nos ámbitos tecnolóxicos en xeral e do hacking máis concretamente. Pero aínda máis, pretende crear unha comunidade que avalía criticamente as narrativas hexemónicas arredor das tecnoloxías, os aspectos de modernidade dos seus supostos occidentais subliñados e as súas inflexións capitalistas inherentes, entre outros.<br />
O obxectivo principal do evento é desenvolver kits que se centren na interacción co medio natural no ámbito da enerxía.. o obxectivo principal pasa pola captación de enerxía do medio natural, a través dos aeroxeradores. Estes kits de enerxía serán escalables e poderán utilizarse tanto como material pedagóxico como para instalar centrais eléctricas específicas do sitio en diferentes sitios tamén. Este traballo ten un compoñente contrainfraestrutural: unha posible consecuencia sería capacitar ás persoas para xerar a súa propia enerxía en lugar de depender de grandes empresas e moitas veces extractivas.<br />
