Hey, how would you make an open source JUMBO TRON with FAST SPI?

Hey, how would you make an open source JUMBO TRON with FAST SPI? We have 100 boards each 16x8 pixels coming soon.

What chipset are the leds based on? That will have an impact.

WS2811: Here is the part: http://www.aliexpress.com/store/product/5050-SMD-RGB-LED-with-built-in-WS2811-IC/701799_656558600.html

Also, some thoughts on data, this is 12,800 LEDs you are talking about, each frame will be 38,400 bytes which means for 30 frames per second you need to be able to move 1,152,000 bytes per second, or an aggregate data rate of just under 10mbit.

Also - memory will be something to think about - arduinos have 2-8k of ram on them each, and the teensy 3 has 16kb - you can use multiple controllers together to spread the load out, there’s examples out there for how to do that.

Thanks for your insights on this project. I think we will have to hold off on this for this years conference.
