Its been a while since I have done much with electronics, so I need a little help. I am trying to figure out how to make a 5 to 10 minute timer that drives multiple LEDS once I open a door on my tool box. I plan on using 3 NiMh batteries from a rechargeable led Light bar. I need something that draws minimum current, and starts timing when power is applied to the entire circuit (I plan on using a single limit switch so that I have only one input I have to worry about bumping, breaking or catching my fingers on) Any help, suggestions, schematics, or general education would be greatly appreciated.
