Let’s Make Robots user Rob “renkku” Re is getting some pretty good results from his sound-activated camera flash system, called the Picture-Axe. Built around a Picaxe microcontroller, it has a sound detection circuit and a silicon controller rectifier (SCR) to drive a flash directly. The microcontroller can be used to adjust sensitivity and flash delay.
