Theremin are awesome, but designing Analog electronics is hard...

Plasma is awesome, but winding a Tesla coil is hard...

So, lets do it digitally, and use mass produced components to create a tiny, MIDI compatible, digital Time-of-Flight, plasma-speaker Theremin!

    OK, plasma speakers are GO!

    Here's the rough schematic for the plasma lighter:

    Two opposite PWM signals are fed into s1 and s2 to pulse current though the coils in the high voltage transformer, at ultrasonic frequencies.

    I plan to pulse the PWM signals to generate audible tones. More to come soon.

  • Project started!

    OK, I've stripped down a dual-arc lighter, and reverse engineered the circuit.

    Seems to be just 2 mosfets, a few resistors and the pulse generator/LiPo charger that I won't be needing at this stage.

    I've started coding a Arduino Nano clone to generate the note, as done previously here:

    http://ultrakeet.com.au/write-ups/modulated-arc-lighter

    After that, I'll add in VL53LOX TOF sensor support.
