LED rotation generation
I need more time. I just fell in love with this cool pov (persistance of vision) tool. It’s a single led row with eight leds that displays a message line by line. And of course this is only visible when it’s rotated (or moved very fast). There are other projects on the web mounted on bicylcle spokes but this version (a small metal pipe on a lanyard) is so much cooler.
I sooo want to build one of these. Preferably before someone encounters the commercial potential (so far the idea is only used for alarm clocks, as far as I have seen) and every soccer fan has something like that.
Here are more pictures from the guy that build it. Found via hack a day.
