Just learned about this sick feminist hacker group that made a technique for creating PCBs out of locally harvested clay instead of plastic! Ofc the PCBs will have to be pretty simple, but ill bet you could totally make an arduino with this!
Really want to test this out and do a workshop at Sandbox (our local hackerspace) if this works!
