smoked or mirrored glass would have been great but much much more expensive!

you should put a mirrored or smoked glass so all the electronics are hidden but the light would still be seen and would look awsome!!!

I wonder why yours are so much brighter than mine. I see in another thread (animations) you’re updating at 50Hz. My panel has to be refreshed at 70Hz (IIRC) with not much margin for error. I wonder if that’s part of the reason for the brightness difference.

Hi, yes the panels are very bright. It is possible to read them under normal daylight conditions. Sure it gets harder when the sun direct hits the display.

[...] a lot of LEDs, and a little bit of glass cleaner. [Tobias] spiced up his IKEA coffee table by adding 6144 LEDs. This is a larger realization of SparkFun’s LED coffee table which used 64 8×8 modules. [Tobias] [...]

Nice. Is it visible in a fully lit room? I have one of the Sure panels but am disappointed by its (lack of) brightness. Yours looks brighter somehow.

After optimizing the code I managed to read 96×64 pixel images from FLASH and displaying them with about 350 frames / second (when doing nothing else). So I will go for a bigger AVR (thinking about Mega644p ones) to have some free I/O’s to connect some NES controllers and some kind of memory and maybe bluetooth.

Two arduinos, each handling 1/2 the display, and passing common elements between them? One calculates, takes half, and passes half to #2?

WOW is all I can say.

Hi Tobi,

Looks great. Any chance of posting the code so I can have a go with my own displays?
