    persistence of vision (pov) wheels?

    My friend, who knows I am into bikes, pointed me to some cool pov wheel sites that he had found.

    [more info here]

    Description from above page:

    Each stick is 9" long with 32 LEDs, a microcontroller and hall-effect sensor. As the wheel turn, each stick detects a magnet attached to the chainstay which allows it to calculate current speed and 'sweep out' an image. While biking, the image appears to be static, floating inside the wheel, 3 or more sticks are needed to create a persistant image at any reasonable speed.
    He originally stumbled on the material in a friend of a friend's blog post which has a lot more information as well as instructions.

    Anyone seen this before? Forget spoke cards, this seems to be the ultimate decoration .

    cool! try http://www.hokeyspokes.com/

    they sell basicly the same wheel light system, but different designs.

    It looks like the version turd linked to would be much smaller, lighter and less expensive for doing text messages. I wonder if three or four of those could be run off a generator hub?

    Despite the coolness, I would be worried about the lights getting jacked. I guess only for special occasions .

    At the least, that would require wires. At the most it would require some sort of electrical contact system that allowed the wheel to rotate freely. Think of a trolley running on a circular track with the over head wires and contact.
    From Craig's List: IF its a singlespeed that means----all the other parts are broken cut off and dumped...dont buy singlespeeds, the bikes will make your balls fall off

    * no -- it's NOT ok to contact this poster with services or other commercial interests

    I was thinking you could run the wires directly from the rotating part of the hub to the lights on the spokes, bypassing the normal wire-out-the-side feature of generator hubs. Front wheel only, of course. It'd be a self-contained special occasion wheel to throw on the bike for critical mass rides and such.

    It'd probably be better to have the mass of a generator in the center rather than 6/9/12 AA batteries further out towards the rim. Not being a weight weenie, but putting it in the middle would minimize its effect on braking and acceleration, physics of rotational momentum and all.

    i just redesigned the small POV toy and started selling kits for those who are not experienced in making PCBs.
    i've redesigned the large POV toy to be double sided...but im having difficulties figuring out a good (waterproof?) way to attach them. i usually use lightweight rechargable cellphone batteries. never had any problems.
