Diode – Build, program, and simulate hardware

Edit: I am ex EE. I will note that it's horrible using this view. It is marginally more horrible than using breadboards in reality. Schematics exist because reality tends to suck or have inconsistencies. For example TO-99 packages come in different pin orders, so 2N3904 has the opposite order to a BC547. Also breadboards tend not to have full length bus bars depending on vendors. At least though in this form it's an ideal representation though which doesn't have parasitic capacitors, inductors, dodgy contacts and no ground plane all over it.

It is good fun though :)

AIUI the best frontend is kicad, though I never really tried that, I just wrote the text files by hand.

Don't add unnecessary complexity just because AIs are good at vibecoding threejs demos (edit: even if this particular demo seems to predate vibecoding and was likely used for training instead of being the product of inference).
