The APC theremin doesn't use radio waves, but instead uses darkness (and light) to control the PWM and frequency of the waveform it produces. Based on the Atari Punk Console it won't produce the subtle and glaciated tones of a vintage RCA Theremin, but the harsh buzzing square waves that we all know and love instead.
2x CV in, 2x Knobs, and 2x Light Dependent resistors can modulate the circuit.
Each oscillator has three ranges too. Don't expect 1/V Oct tracking or highly linear operation of any of the controls. Expect fun and chaos instead !!!
Depth is a skiff friendly 25mm, +12V only, 2x5 pin, current is pretty low. Will measure it soon tho.
Demo's, better photo's, more specs, etc coming soon.
