Just a thought from a newbie: I wonder if anybody has thought about trying to accomplish the same thing with an old fishing reel by basically making the reel a generator/motor, adding a capacitor/battery, etc. May be a great gift for all those fishin' buddies out there.

Axle. Angle connector.

Crank the other way, or reverse the LED. Try putting in two LEDs of different colors and opposite polarity. Then you get a different color depending on which way you crank the motor.

Nice little Instructable! I fancy having a go at this and maybe adding a capacitor battery and substituting the yellow led for a blue one. Cheers for that!
