Wheel display
Display messages, pictures and logos on hubcaps or spokes | |
This uses a rotating bank of LEDs like the rotating displays.
This device is mounted on a wheel with the circuitry counterbalancing the lights. A coil mounted on the rim passes a fixed magnet on the fender or fork that tells both allows the device to orient the image the right way up and also provides
power.
NB/ This is a novel gimmick or advertising display, but not something I'd put on a Bentley, so please no comments about looking silly.

spinning disk mechanical tv
http://www.tvhistor...%20TV%20Picture.htm 1920's mechanical tv system used a blinking light behind a spinning metal disk with a spiral of holes drilled in it. [macrumpton, Oct 04 2004, last modified Oct 21 2004]

It would also be illegal to use whilst driving (on public roads), but i can see this appealing to the neds!
The idea gets a (-), but as a marketable product it's a (+). |

You could put it on a bicycle. |

This would look silly. Imagine how much it would ruin the look of a lovely Bentley. |

If so, I wasn't around and my search didn't bring it up. If someone posts a link, I'll happily delete the idea. |

I made something similar to this in
1976 for an art school project. I
attached a row of 75 leds to a spinning
arm activated by a row of contacts that
skated on a glass disk. On the disk I
could make designs in adhesive copper
foil that would be reproduced in the
leds light. |
|
|
Since then I have seen frisbees and
other flying toys that used a similar
concept as well a clock that showed the
time using an oscillating wand that had
leds on it. |
|

The whole concept is very similar to the
early experimental tvs that used a
blinking light behind a spinning metal
disk with a spiral of holes drilled in it.
