Description coming soon....

Experience from the first workshop at Dimension Plus LAB, TW

Prepare 400% scaled, printed, laminated and cut-out smd parts.

Download the files from the github.

Discuss the difference between the "schematic" representation and "physical" implementation

Start layouting and drafting the correct connections with pencil

we should add some sticky tape to fix them...

Overlay with a transparency sheet and draw the circuit traces and pads

Make sure you take some photo of your layout to refer to the part's position later.

Scan (or photo), scale it back down, print and etch the boards

Take a decent photo, check for reflections from lamps and stuff. Edit the photo in GIMP, to select all surrounding areas and invert the selection. Fill with FG (black), copy, create from clipboard -> new file. import in Inkscape, rescale to original size (some markings on the drawing would be great). Last edits can also be done in inkscape, like adding logos, version numbers, open source coconuts or defined drill holes, cut-layer etc...

Etch the boards or send it for manufacturing

Panel, Pring and etch, or use pdf2gerber to send it for manufacturing

Workshop at GOSH2017, Santiago de Chile

See discussion on GOSH Forum.

We have been testing the new workshop that i developed for GOSH, called diy-CAD (do-it-yourself Children Aided Design), specifiically for the Gär Lämpli project (fermentation lamp). The core idea of the workshop-kit is tool for creative designs of printed circuit boards, introducing basic concepts of Open Hardware being something to re-design for your own use. going from an open/shared schematic and bill of materials to a manufacturable board, using SMD (surface mount devices) components. The design tool is mostly pen and paper, where the footprint of the parts are scaled 400% and can be freely rearranged, and then a copper layer can be painted to draw the functional board design by hand. This was the first time the kit was tested and i am very thankful for feedback if this is useful at all, or other uses of it.
