Hand crank mobile phone charger

This is my first instructable

I made this for my HTC wildfire which charges from a 5v power supply
al you need for this project is:

1 x handcrank tourch
1 x phone charger USB lead

all you do is replace the LED connections with the + / - wires from the USB lead and its done

or even better you can wire it to a female USB lead and charge anything USB

You can just google "hand cranked flashlight". You can also find these flashlights in most stores that sells outdoor stuff.

You could use a 78L05 regulator, but you'd need up to 7 volts and it takes 3 ma quiescent current, so you'd want to use a switch to keep it from draining the battery when not used.

You can get the hand crank flashlights for 5 bucks or less anywhere you find cheap electronic stuff. My only concern would be that there is no regulator involved, and you would have to be careful of too much voltage when you "cranked it up". I keep a crank up torch/flashlite in every one of our vehicles so we never worry about the dead batteries in the flashlight gig that I think everyone has endured. Good thinking and I need to take apart one of those cranking lites to see if it does have some kind of limiting device, or if we could make one with some old diodes and a heatsink?????
