I sure hope there's a contest somewhere for the simplest circuit cause I think I might win. I've designed a sound synthesizer circuit that essentially has just one component, a little 8-pin integrated circuit with only 4 connections to it; 5Volts DC and Ground, an input from a logic level flasher signal and an output to an audio amp & speaker. You can hear a recording I made of it on my website under the 'Sound Synthesizer' tab, just click on the "RR Crossing Bell" link or go to

While you're there, browse around. You never know, you might find something interesting!
