Huh, thanks! It appears you need just a few more parts than the flashlight and bike, but still quite simple. i like it.

All the parts are actually in the flashlight I carry in my truck. It's got a hand crank, small dc motor and charging circuit for a rechargeable battery pack. One broke so it became a part source for a couple projects.

Sweet! By hand crank i assume you mean a dyanamo? Like the radios that are advertised on Coast to Coast AM? Appliances with dynamos are good to have around anyway. i should look into them. Especially if i end up getting a new job.
