The Revision 2011 demo party that brought us” table for two” a little while ago along with some super demos for PC’s, retro, and state of the art, has also brought us the Photon Banner(google translate). The Photon Banner is a 96X24 led matrix that was made with (of course) 2304 5mm leds, and a atmega 644 clocked at 20MHz.
The end result is a 192cm X 48cm display area that uses the single micro controller, that has been beefed up with 2 megs of SPI flash memory, 6 driver boards, and took about a month just to construct. The software to drive the show took another 15 days, and it is pretty darn impressive.
The website above contains a bunch of photos, parts lists, and schematics. Before you go running off you should join us after the break for a couple of quick videos.
