Persistence of Vision (POV) gadgets are always cool and are easy to impress the guests. If you’re too stingy to purchase one, you could always build one yourself as a user out there managed to build such a setup himself using a PC cooling fan to spin the PCB blades. The animation effect is created thanks to illuminated LEDs which are synchronized. The board is powered wirelessly between a base transformer and a coil on the board. The firmware that powers this clock apparently took a good 3,000 lines of code, so it doesn’t seem like something that Joe Average might be capable of doing. Still, it’s a cool clock, and you can check it out in action in a video after the jump.
