Attach this fun persistence of vision toy to your shoe and write messages or patterns while you walk, run, or dance! By Dan Goldwater
The Dance Messenger is a fun persistence of vision toy. Attach it to your shoe and write messages or patterns while you walk, run, or dance!

I used a fairly generic circuit board I had lying around for this project. The circuit is really simple though; it’s just an Atmel AVR microcontroller, 10 LEDs, a programming header, and a few resistors and capacitors. You might want a button so you can turn it off. The board I used is mostly surfacemount components, but all the parts are available in through-hole form so you could easily build this on a proto-board. Figure C shows the ...
