Dirt Simple POV LED Display
In case you don’t know, POV (persistence of vision) is the blur you see when you wave an object quickly. In this case, by flashing LEDs at certain times while an object is waved, a message appears in the air. Easily build your own DIY POV display.
It has a built in accelerometer so it can detect how to properly display the letters/characters when moving at various speeds. It has a built in “letter generator” I suppose you’d call it. So basically instead of typing B10001 B10101 etc to get the letter A, all you have to do is tell it to type “A” and it already knows which segments to illuminate. An outstanding yet simple project.
You can buy POV Kits too: Bike spokes or miniPOV.
