04/13 - Battery Charge Detector
Copyright ©2006, Alan Bryant
I wired up a more or less experimental battery charge level detector with a couple (normal) LEDs and 220-ohm resistors. It seems to work pretty well. When the lights glow at almost equal brightness, the batteries are fully charged; as one grows dimmer than the other, the charge is dropping.
