AA powered microcontrollers

[sprite_tm] sent in this nice little single AA battery micro-controller power hack. He’s using the uc to generate a PWM signal for a simple voltage step up circuit – the catch is that the controller has to start working before it can generate the signal. He came up with a nice little solution to this caveat – a push button start that gets things rolling once the coil charges up.

Thanks for the tips guys, keep em comin.
