Ohmsville

Ohmsville is a 1980s electronics lab that really works, in your browser.

Remember the Radio Shack "200-in-1" kits, the ones with the spring terminals and the wires you hooked between them? Ohmsville is that kit, rebuilt with a real circuit simulator underneath. Every part is modelled. LEDs light, speakers sing, capacitors charge, and if you wire something wrong, it smokes.

This channel is the shop class. Each video is one lesson from the Intro to Electronics course: what electricity is, the loop, resistance and Ohm's law, series and parallel, capacitors, diodes, transistors, oscillators, sensors, reading schematics, measuring, and safety with real parts. The footage is the actual bench doing the actual build, so what you see is what you can do yourself the moment the video ends.
