LED Wave Display
This is a LED Wave Display. When you want to stand out from the crowd, just stick your hand out and wave away. Custom message will be displayed right above your head.
On the other side, this is nothing else but a simple POV system. A few LEDs and a microcontroller together usually do the trick pretty well. In this circuit we also have a simple accelerometer switch, but it is nothing to worry - it is a simple mechanical switch constructed with a little weight mounted on a brass (looks like it) sheet.
I really wonder why no GSM phone manufacturer ever mounted this on the back of a phone for easy cab hailing. Now that's a cool idea for a project!
