[Collin] demonstrates this technique in the video, constructing a simple LED flasher circuit. He says that the process works decently enough, and was kind of fun to do. He does mention however ...

Maybe I shouldn’t be surprised, the led flasher modelled ... on the right of the circuit are pretending to be an led. Back to LTspice now, to get the thing working from 4V rather than 5V, to find some ...
