2xs,
Can you post some more info about the circuit you got from the forever flashlight? I am working on a model maglev train project, and want to use electromagnetic induction to charge a large capacitor on the car of the train to power a small emergency baking system that will only be utilized for very short intervals. i'll be able to induce a pretty good sized voltage to charge the cap (about 1-2v per coil for 4 coils). so source voltage won't be a problem (like shaking may be). and i can easily clean it up and get the voltages and time constants that i would need, i'm just curious to see a layout of how those forever lights work without having to tear one apart (although i am tempted).
any help/suggestions from you and/or other members would be appreciated.

ps. don't mean to hijack thread, sorry if it seems like that, but i felt it was enough along the same lines and i'm asking specifically about 2xs's specific circuit.
