Twinkle Toes

Twinkle Toes
Add a flashing, tricolor UFO to your roller skates

Skatetown is our local roller rink in Bloomsburg, Pa.
For years, it's also been my artistic LED experiment
laboratory. I started by taping single-color LEDs to
skates. They were so popular that one session on
the floor looked like a swarm of fireflies.

My latest LED invention is the UFO Toe Stop. It
uses a disk-shaped "flying saucer" unit that con-
tains a red, green, and blue (RGB) LED. I wanted to
blend the colors in interesting ways, so I wired it to
a PIC-controlled RGB microcontroller that comes
with programmed routines such as fixed colors,
fast-changing rainbows, or dazzling strobe effects.

I also used some translucent jam plugs (small
bolt covers used in skate dancing) that I bought in
the rink's pro shop as light diffusers.
