A friend of mine just showed me this new item and i was just wondering who is going to be the first to apply it to their christmas projects for Christmas 2009?

Very cool! At only 60 bucks that is worth looking into.

Wasn't this a prize for a recent Instructables contest?

Officially on my want list - would look cooler on my bike than spokey-dokes (or footy cards) ;)

Check out Ladyada.net (http://www.ladyada.net/make/spokepov/index.html)

My son and I built a similar unit 2 years ago for our bikes.

For a display, I'd suggest taking a front wheel and fork assembly from a bike and mounting a 1/4hp electric motor to the base with a friction drive.

I thought i saw something like that before but i was not sure. The process seems pretty straight forward but the use for that is endless.

Got me thinking.. The bit that i dont' have an answer for is how to get control to the boards that are spinning.. THe Ladyada board doe'snt have one of those..

In a sequenced display you'd need a way of getting some sort of control signal.. I think i need some kind of wireless link.. And it woud'nt need to be too fast..

The 2 most common ways appear to be a slipring or RF. Elsewhere on the web I read of someone who successfully used a slipring, but you may need to add some noise filtering due to sending the signal thru a mechanical movement. I think they used a 12V signal and it worked reasonably well. There was also another approach that used the armature of a motor but I think that was just to supply power and not a data signal.
