Pedal bike with TRON bike lights

Ingredients:

  • Electroluminescent (EL) wire that glows when AC current is applied to it.
  • An old stepper motor to provide variable AC power
  • An old cell phone charger wired in reverse to convert low-voltage produced by the motor to high voltage required by EL wire.
  • A bicycle
  • Human power

The result: a bike that changes in brightness (and even its color, a little) depending on your pedaling speed, a little bit reminiscent of a TRON lightcycle. In the below video, the TRON bike maker is on a swing bike so it looks kind of funny, but you get the idea.

View full instructions at Instructables, and be careful not to shock yourself with this project. Unless you’re into that kind of stuff.

P.S. Twitter contest deadline is noon. You can’t win if you don’t enter!

    It’s gotta be significant. Stepper motors are hard to push.
