[Ryan]‘s [URL="http://rucalgary.hackhut.com/2012/01/19/rgb-pov-display/"]cylinder POV display[/URL] is an amazing piece of work. Right now it’s impressive sitting on his workbench, but we’re sure it would be astonishing hanging above the middle of a dance floor. There are 64 RGB LEDs on this display and they’re certainly bright enough to liven up any space.
Power is provided through a slip ring. The ground is connected to the shaft of the motor [Ryan] picked up at an auto parts store. It’s an efficient way to do things, but the display can only be controlled by whatever image is stored in the ATMega1284′s flash memory. [Ryan] admits this isn’t an ideal setup so he’s working on a ZigBee or Bluetooth connection.
We’ve seen some [URL="http://hackaday.com/2010/11/13/lots-of-spinning-pov-goodness/"]amazing spinny[/URL] [URL="http://hackaday.com/2010/08/09/spin-peggy-get-3d-pov/"]POV cylinders[/URL], but [Ryan]‘s build looks amazingly professional. All the board files, schematics and code are uploaded, as well as an image converter for BMPs and PNGs. Check out the demo after the break.
