Mentors
Marc Dusseiller aka dusjagr (Switzerland)
Marc Dusseiller aka dusjagr is a nomadic researcher and workshopologist. He is part of the Center for Alternative Coconut Research, co-founder of SGMK, Bitwäscherei Hackerspace Collective and the Hackteria network. Before travelling the world for making DIY / DIWO laboratories for creative biological experimentation with living media, Marc entered the world of DIY electronics, designing printed circuit boards for synthesizers and organizing workshops and festivals mostly in Zürich, Taipei and Yogyakarta. He was the co-organizer of the different editions of HackteriaLab 2010 - 2020 Zürich, Romainmotier, Bangalore, Yogyakarta and Klöntal, Okinawa and collaborated on the organisation of the BioFabbing Convergence, 2017, in Geneva and the Gathering for Open Science Hardware, GOSH! 2016, Geneva & 2018, in Shenzhen. He also loves coconuts.
Helmi Hardian (Surabaya, Indonesia) | BIR residensi
Helmi Hardian is a grassroots artist and ghetto scientist, with a specific interest in cooking and smoking at the same time. He lives in Surabaya, the city that is well known for its industry and technology, as well as being the center of electronic component trading (chiefly, Pasar Genteng). Hence, almost all of his works are closely related to science and technology as the medium of creativity. He is the co-founder of Waft Lab, a creative-based initiative that works at interdisciplinary practices. Currently, he focuses on tech development through DIY/DIWO culture and playing his role in researching, hacking, or deconstructing daily materials to provide some devices with new functional aspects, as well as developing workshop kits, lecturing contents, and presentation materials, which aim to learn, share, and exchange knowledge.

Background
"A workshop where participants will build small electro-mechanical solo drum machines from single DC motors and small circuit boards. The workshop will experiment with different kinds of sounding materials (metal pieces, stones, springs, paper, etc), where the machines will oscillate freely and develop their own individual sound quality. Once built the machines will be used to explore fundamental musical structures." - from Ralf Schreiber
As always, Ralf's workshops are fantastic examples combining technological simplicity, DIY electronics & soldering with a broad artistic and aesthetic creative potential for collaborative sound / kinetic art-making to explore together with workshop participants of all age groups and backgrounds.
During the TUAK residensi, we have picked up on of Ralf's workshop, the Record & Play, and experimented with different models for using it as a local workshop module in Indonesia. During the conversations with Ralf, we also found the new code, developed my ChrisMicro which allows to control 2 motors with a single ATTINY85 chip, using classes and object oriented code.

Paper PCB version, Thailand Jan 2024
Paper PCBs is the fastest and the most flexible rapid prototyping system developed by Wolfgang Spahn since the early 2K. Paper PCBs are Printed Circuit Boards (PCB) based on paper print outs combined with copper strip boards, also called Veroboards. With these boards one can easily build and modifier real electronic circuits that could be used in any devices and applications.
For all kind of media installation based on controller and electronics one requires printed circuit boards (PCB's). It can be quite a task to get the perfect one that matches your needs. Due to industrial standards it takes some time and money to get them manufactured. Another option is to create them by yourself, but most likely you'll end up with a lot of dangerous chemicals and find yourself drilling hundreds of holes.
Paperboards or Paper PCBs are a smart way to avoid the trouble. It is an open hardware system that allows you to create PCB's easily. You simply need a drawing program like Gimp, Inkscape or (Photoshop) to design or modify them on your computer (Fritzing will also do). Just print it and stick the printed circuit on a standard protoboard (available at every electronic shop) and voilà - there is your proper PCB. The system allows you to get an individual colorful design, too.
Experiments with Arnont and Workshop in Chiang Mai
How to make sound?
Wenn du ohne Gravitation schlagen willst, kannst du die Motoren ja noch mit ner Bronzefeder (30x2x0,1mm) modden. 0,1mm dicke Bronzebleche solltest du finden können. Lüsterklemme auf Motorachse schrauben, Enden der Feder an Klemme & direkt ans Motorgehäuse löten...fertig.
Interessant wird es auch mit beidseitig elastischen Anschlägen (Bronzebleche)....oder den Schlegel mit Silikonschlauchstückchen/kleinen Federn bestücken. Da bekommst du Doppelschläge / mechanisches Delays...
Testing to build the circuit on proto-board, and doing the mechanical spring with cable ties. seems to work ok... the circuit is a bit complicated to build like this for beginners...
New Dual Motor version
With the new code, we have now the option to add 2 motors, which can make especially the individuals sound sculpture more complex to take home. Also we removed the pull-up resistors to save some parts. Now only the reset pin is still available... it could be an option to flash the chip and disable reset and add another function. mbe a potentiometer for speed or something?

Making the pisibi
Workshop "Simple Kinetic Sound Sculpture" at Pazar Kaget, GOR, Bandung
Dusjagr was invited to visit GOR (Gelanggang Olah Rasa), in Bandung, and participate with a DIY electronics & art workshop during their weekend Bazaar. We took the opportunity to try out the new workshop concept adapted during the TUAK residensi, where we redesigned new PCBs for the workshop "record & play" by Ralf Schreiber.

"ultra-mega terlambat posting, tampak suasana lokakarya @fksm.indonesia merangkai pengontrol motor dc untuk kebutuhan ini dan itu. lokakarya ini diadakan oleh kemendikbudristek dan @arcolabs.id di taman budaya mataram ntb, kala itu sekitar awal juni 2023. konversi desain menggunakan inkscape extension svg2shenzhen bikinan badgeek @manticore_ , sayangnya nggak sempat order ke shenzhen, akhirnya balik ke manual lagi XeroX dan aut666n tak lupa pcb bolong. kami dari @waftlab mengucapkan yaey"
