GGW Posted November 18, 2006 Report Share Posted November 18, 2006 I ran across a circuit that looks like a good idea. It's a LED that lets you know when your battery is loosing power to your active pickup system. LoBat I've checked around and can't find an equivalent DIY circuit. Shouldn't this be fairly a simple design of dropping the voltage across a resister to just above the trigger voltage? I'm not sure what the intregrated circuit is doing there and why they claim their circuit uses so much less power; they still have to light the LED, right?
