Retina is my new project – it is an 8 foot wide by 4 foot tall 8×4 multicolor LED display. The kicker? Each LED is 10watts and have an advertised white-light output at 500 lumens! That puts the combined power of the array at about 320 watts, with a white-light output of 16,000 lumens. I will be posting more details soon – but here is the solidworks rendering I made of the concept design. Each of the dark squares in the grid is a 2×2 inch printed circuit board that holds an LED and it’s driving circuitry.

I’m still investigating different technologies in driving this project but it looks like I’ll be using 6 TLC59401 IC’s from Texas Instruments to generate the PWM signals and using the TL4242 as a constant current driver for each channel.  I plan on using a WiFly module for wireless communications at high speeds without the need for an xbee module to carry around with me. To interlink all of the communications and operate the TLC59401′s I will be using an AVR microcontroller from Atmel (since I already have the programmer and I am familiar with the chipset)

To be continued..
