First of all, let me say that I'm sorry if I posted this in the wrong forum. I'm new and unsure where to raise this question at.
Recently built a POV (Persistence of Vision) setup for my bike wheel. I love the way it works and how it lights up my wheels, but I don't like the way I was forced to mount it. Its currently powered by 3 AA's in a pack, zip-tied to the spokes, as close to the hub as possible. The weight of the batteries can be noticeable at times. I want to develop a way to mount the battery pack (or any future power supply) elsewhere on the bike, and route power to the wheel. I've looked into hub generators, but then how would I get the wires for my POV setup back into wheel? Do they sell setups that are basically an empty hub generator (no generator, just a hub with the connections to run wires into in a manner that doesn't twist them up when the wheel spins)? Any thoughts, ideas, or leads in the right general direction would be greatly appreciated.
