The Countdown to Maker Faire Bay Area is On!


Breadboardless mini synthesizer

Breadboardless mini synthesizer

From the MAKE Flickr pool: This excellent “bug” synthesizer created by “noise performer” 23N!.

A mini synthesizer (VCO/SLF/Noise) based on the complex sound generator SN76477.

Three capacitors and three resistors are used to vary the sounds.
The resistors can be replaced by a photoresistor (CdS), a phototransistor or a pot.
