Nathan and company have always been supporters of OSH, but now they’re going to be putting links to the engineering files up to at least some of their kits. The first is the ClockIt kit, an alarm […]
In this clip from FMCG, Ken responds to Jeri’s capacitor deconstruction with his own very visual (and very mechanical) demonstration of how voltage is generated and how you can build a simple capacitor, with aluminum foil and plastic, to generate charge mechanically and dump it into the cap (analogous to how a Wimshurst machine works).
