Digital SMD Theremin

This is my Multi Master Micro Noise Mixer. This is a turn table producing real 1 bit music. I like it so much. It is so simple and so much fun to play around with. It's actualy simply bulit form four micro noise circuits played by a printed sequencer disc. The four light sensors of the micro noises are aligned in a row and modulated by the black squares printed on the transparent disc. This makes it a four track 16 (or more) step sequencer. The signals of the four micro noises are then mixed together.

The lower eight potentiometers control the four micro noise circuits. The there is one knob for the volume and one to trim the motor speed. On the top right side there are to switches, one to switch the whole mixer on and the other one to only turn the motor on and off.
