I would like to build a decently bright LED flashlight that uses a capacitor instead of a battery to power the LED. I'd like to use some sort of magnet in a tube of windings to generate the current - also may consider a little solar panel. I know they sell these "forever flashlights" for around $20, but I'm a handy, do-it-yourself kind of guy and would like the satisfaction of doing it on my own -- except for I know crap about electronics. Ok, so I know a little.
I just thought capacitors took a little trickle charge until they reached capacity and then zapped out all the voltage like a little lightning bolt, but I guess I was wrong.
So, any ideas, tips, pointers, schematics or ridicule will be accepted.
thanks -
