A Light Hum is a AC sequencer console that allows me to control the brightness and sequence of 8 light bulbs. Each bulb has a photocell teremin attached to it to convert the light frequency into audio frequency. I am using different photocells/phototransitors, resistors and capacitors to generate different tones. The heart of the AC sequencer is a board designed by Mark Kleback and Ezer Lichtenstein. Check it out, its pretty freaking awesome, kleebtronics.com/sequencer.
