Lazyweb: Kinetic powered LED Diabolo

I have been thinking a lot, regarding the idea about kinetic powered LED diabolos,

A while ago I bought some inline skate wheels and they work exactly how I thought. However trying to attach them to the diabolo is more tricky that I thought.

Really I need to sit in a hackspace and just go at it for a day or so.

In my head there are two ways to go about this.

1. The standard diabolo route with a spinning axle.
   I could extend the diabolo axle and attach the inline wheel loose to the outside. In theory, the diabolo would spin as one piece and the loose inline wheel which has a bit of weight would generally spin far less than the diabolo axle. With this, the dynamo will light the wheel. Of course this might not work.
2. The geared diabolo route with a static axle.
   This one is much more complex but a geared or bearing diabolo gets incredible speeds because the axle has a bearing within it. The big question is to either extend the bearing out to the inline wheel or add a bearings to the inline wheel’s dynamo?
   I also been wondering if the cups could be used to hold the inline wheel?

Ultimately it seems all possible but it just needs time. I write this encouraging others to give it a try. Maybe I’ll get some time off and get myself down to Hackspace Manchester (hacman) or DoES in Liverpool?

Someone tell me the physics don’t work one way or another, heck tell me how it could actually work…
