Hi there, I think having spoke mounted lights for side visibility is a Good Thing. I've tried out the little battery ones but they don't last very long and are generally too fiddly to turn on/off, etc, while the POV stuff like Monkeylectric seems overkill to me, and still needs batteries. Feeding something from a hub dynamo which in exactly the right spot would seem smart, but the only way I can see to do it is with some sort of rotating contact/brush on the forks, which seems riddled with problems. I just had a bit of a mind-explosion on this while procrastinating and thought I would give it a try. So my thought: Wind a small parasitic coil onto the outside of the hub (in the gap between the spoke flanges) to capture some of the energy whizzing about inside (from the AC coil if nothing else) and feed it into some LEDs on the spokes. I don't imagine it would be very efficient, but it would only need a few mA to light up some 5mm LEDs. I've just tried this with 5 turns of fairly thick wire, and spinning the hub axle with my power drill (with a dummy load attached across the main terminals) registered 0.0V on the 200V AC position of my multimeter (the smallest setting it has in AC). I really haven't a clue here, so I thought I'd turn to the collective wisdom of CPF and see if anyone has any bright ideas. Can anyone suggest what I might do to make this work, or if it is even be possible/a good idea? Cheers, Jem
