Device0026

This is a light-controlled square-wave generator with a pulsing effect, hand-built into an Atari paddle controller. These were originally built by Gemini for the Atari system. Pitch is controlled by a light sensor, speed is controlled by the knob, and the trigger is power. At high speeds, you can get some interesting throaty sounds. For more precise control and a wider pitch range, experiment with different light sources.

A red LED pulses with the sound. It can easily be connected to amps, effects, recording equipment, etc. At the end of the original cord is a 1/4" plug, and running from there is a wall adapter for power.

This was built as a set of four. Two have a home as a part of Night Toilet's rig. Here is a video of them performing at Clocktower Gallery in New York.
