Today is POV day it seems… Oscar writes –

Here is a cool project from Spain featuring an Arduino POV and some 433Mhz Wireless modules. This project includes an IR sensor to auto-calibrate the display timing on each complete loop. This allows for very accurate precision and stability when drawing on the air! This Arduino POV is based on a old floppy disk enclosure and a old CD-ROM driver and an old car-radio for the main DC motor. Cheap and fun! I’m improving the wireless code to control text from PC to the board remotely connecting together to a USB port.
