A Non-friction bicycle lights dynamo (Tumbling magnet)

[iwicom]

This is a new generation bicycle light system with a unique tumbling magnet generator.

No battery is needed, no friction on any parts of the bicycle. The lights flash regardless speed of the bicycle and weather conditions. Very bright.

It's a pretty good system, I've been using it for about a year now...Looks like a christmas tree going down the road but then again I have extra magnets and an extra coil set on mine.... 

I've also tried building a regular gen out of them... works pretty good for the little amount of torque it take to turn it.

here is a link to my gen setups: http://www.leebell.net/workshop/bobble.htm
