I got discouraged with my Bike Lighting project. It was going to take 2 magnets spinning on the spokes tightly mounted, which I was thinking would be big and unbalance the tire, plus a coil mounted on the bike frame which would need some fine adjustment. The alignment was going to need close tolerances and it would get screwed up thoroughly if they ever came into contact. If I can think of a way to make it easily then I might give it a try.
My wife has started bragging about my butt since I've started riding regularly.
