Sheets And Graf

Sheets and Graf contributed an article to Nuts & Volts, Sept 2003, "Lamp Controllers For Special Effects", pg 52. The article includes a circuit that makes a light flicker to sounds picked up with a microphone.

The project is available as a kit from North Country Radio
This is the published schematic.
