Hmm, a tesla coil on a pcb? Well, yes, tesla coil that can generate 5cm arcs into the air, powered from my 5V 3A USB C laptop jack. The tesla coil enumerates as a USB MIDI device and can be used from any synthesizer software like LMMS or Ableton. This project was posted by Niklas Fauth on this hackaday post
. Instead of the usual tall coil that we see always and doughnut-shaped capacity ball on top it took the form of 3 PCBs with spacers between them, and because Tesla coils are simply cooler that way, he had it playing music as an impromptu MIDI-driven plasma-ball lousdpeaker. Now he’s been able to write up the project we can take a closer look, and it makes for a fascinating intro not only to double-resonant Tesla coils but also to Galium Nitride transistors.
