AC Sequencer

Instrument to make music with light or other AC powered appliances


The AC sequencer console allows the musician to control any AC powered appliance that is plugged into it. The first iteration, Light Hum, controlled the brightness and sequence of 8 light bulbs. Each bulb has a photocell theremin attached to it to convert the light frequency into audio frequency. I used different photocells/phototransistors, resistors and capacitors to generate different tones. The heart of the AC sequencer is a board designed by Mark Kleback and Ezer Lichtenstein. This project is completely analog, no computers were used for the audio or the visuals.
