Displaying video and gifs on RGB LED matrices


[Mathieu] was on holiday in China and picked up some fun toys while perusing the numerous electronics markets there. The most interesting things he discovered were a pair of RGB LED matrices. They came in two different flavors, one made for indoor and one for outdoor displays, sporting a 64×32 and 32×16 resolution, respectively.

If you’ve read his blog before you know he is a big fan of LED matrices, so it’s only natural that bought a whole bunch of them and started experimenting once he got home. Using the same Atmel FPSLIC LED matrix control board he showed off in this previous hack, he was able to get the LED matrices up and running in no time. He adapted his webcam project to utilize the new panels, and he added a whole new feature as well. Via MatLab, he can now display any sort of animated gif on the panels, as you can see in the video below. The panels look great, and if we had a few of these around, there’s no doubt we would probably play this video on infinite repeat.

He says that the despite their somewhat questionable origins, the panels are of top notch quality, and he is willing to organize some sort of group buy if others are interested.

    Since you’re such big fans of LED displays, did you see the 60x18m one at Eurovision 2011? http://www.youtube.com/watch?v=OF21pTGtKTw

    I like RGB matrixes, too bad they are quite expensive.

    The work presented here is well done :d

    Been a while since I heard this tune. Brings back good memories.

    Whats the estimated price range for these if we were to go in on an order?

    Hey guys,

    In china, I paid the P4 (the 64*32 indoor one, 4mm pitch made of 8*8 elements) around 160 dollars, the p6 (32*16 outdoor one, 6mm pitch made of SMD leds) around 40 and I’m also able to get 32*32 6mm pitch SMD led matrices for around 70.

    This would thus be the maximum price, as I hope to get good rebates for good quantities :)

    cool, i think some of the gifs are running a little too fast though

    Could it be setup to continuously find animated gifs on the internet, so the show always changes?

    Of course :)
