Re: Brandon's Semiconductor Simulator
#2When spice simulation isn't deep enough... Very educational to show how circuit elements work "under the hood"...for example the LC example doesn't use an L element and a C element as building blocks, but rather it is the two metal plates in close contact which form the bulk of the circuit's capacitance and it is the loop of metal itself which form the inductance.

#3Sebastian Lague has been making one of these and youtubing it, the videos are great here's the latest one https://www.youtube.com/watch?v=HGkuRp5HfH8

Note that these are at very different levels of detail. Lague's is at the digital logic level, while Brandon's is some level around atoms/electrons.

#5Amazing work feels very similar to Paul Falstad page https://www.falstad.com/emstatic/index.html.
This really needs a WebGPU port. Multigrid on a GPU is moderately easy.

#7Fun. I am reminded of the long forgotten Zachtronics semiconductor game “KOHCTPYKTOP: Engineer of the People” [1]

The similarity is likely not a coincidence!
