Simple dynamo generates electricity from shaking it
A prototype battery replacement - generates electricity from just shaking it. How to build a simple alternator / dynamo that generates a current from electromagnetic inductance and really simple to make and improve up on. Includes how to build a simple bridge rectifier to convert the current from AC to DC so it can be used in any circuit. Also explained in the project is how magnets and electromagnetic inductance work to produce the current. Plenty of diagrams, parts lists and step by step instructions to follow.

I'm still working on kicking out more voltage from it and using it charge a small battery. But te LEd-lined jump rope would work - just have to wind enough wire I guess :)

as previously done in a bunch of shake flashlights. Still neat, though.
Mount in vertically on a bike and you've got a tiny generator that makes good use of pothole energy.
