These are Cool! Bike generators with Neo magnets

I saw these on a youtube video with an SSG, so I thought why not try it.

YouTube - Batteryless Dynamo on Bedini

I have one, took it apart, and inside is a sphere Neo with a cylinder with very fine magnet wire wrapped around the tube.

Batteryless Bicycle bike safety LEDs lights, A non friction bicycle dynamo, generator, No battery, No friction, science DIY kit, invention, new product. is where I got mine...


I have ordered 8 (1) inch Neo spheres. I can't wait till they get here.

Questions and Answers

How much voltage and current does this dynamo generate?
About 7V, 25mA pulses.
