Random oscillator circuit for high power LEDs


Posted on Feb 5, 2014

I`m looking for a circuit (the simpler and cheaper, the better) that can drive three or more LEDs at 200-350mA each, randomly flashing/strobing them at 5-20Hz. Input power should be low-voltage DC. A range for Vin, instead of an exact 5.0V or whatever, would be a big plus. It`d be nice if the circuit could handle more than one LED being on simultaneously, but it`s not vital. I don`t have any PIC programming stuff, and I`d rather use fewer components. If I`ve left out anything important,..
