There is a 5m x 20m room. On the ceiling, there will be 6 LED "nodes" hanging per square meter (600 nodes total). Each node is a close-knit 16x16 LED matrix (white-only LEDs, the tiny SMD type 3014 probably). It will look like 600 somewhat randomly distributed lights which, upon closer inspection, are each actually a tight cluster of 256 LEDs. Total LED count on the ceiling is 153,600 (600x256).
I want to use the video-out on a laptop, at 784x196 resolution, to drive every single LED individually (with at least 8 level dimming per pixel ... not just on/off). The goal is to control every LED with pre-rendered video clips, VVVV / Processing, or anything else.
As a final detail, the nodes will be suspended vertically. Since they will probably be mounted on PCB (unless there is another cost effective method of mass producing them), the 16x16 LEDs will only be visible on one side. So unless you have a better idea, we'd need ANOTHER 16x16 LEDs on the back side, mirroring the front (for a total of 307,200 LEDs). Each node would look something like the attached screenshot, but less complex since that example contains stuff we don't need.
It is important that this system be extremely resilient. A video sender / receiver solution such as [url removed, login to view] (which sends DVI or HDMI over CAT-5 and converts to some LED format I guess) seems the simplest.
I am seeking someone to ...
1) Design and specify the method for taking the video signal and splitting it out to the individual nodes.
2) Design the schematic for the individual nodes.
3) Solve the power management requirements of the whole system.
4) Assist in finding and communicating with a factory for manufacturing the 600 (+100 spare) nodes.
