Light Globe Synth

November 1, 2012 · Posted in Uncategorized 

A small synth box with 2 light sensitive Oscillators modulated by 2 pot controllable LFOs.
Circuit using a single 40106 CMOS chip freeformed (no circuit board) inside a re-purposed incandescent light bulb.
Amplification is from a single LM 358 deadbug style under the wooden control panel.
Speaker is a tweeter from a car stereo. Powered from a 9V battery.
Fun to play in the sunshine aswell.
Sound recorded with the camera mic.
Sorry for the out of focus, had trouble with the cam.
