In my project I have to individually drive more than 600 of the following RGB LED strips:
My original idea was to have a ShiftBar (http://macetech.com/store/index.php?main_page=product_info&cPath=1&products_id=10) driving each strip and then connect a bunch of Arduinos + Eth Shields to drive the ShiftBars through Ethernet so that the frame rate gets high enough.
The problem with this approach is that it's a bit costly (adds about $6-7 to the LED strip price) and ShiftBar cannot drive more than 150mA per channel (my LED strips draw 180mA/channel).
My second idea was to use Rainbowduinos as described in http://www.seeedstudio.com/blog/?p=512 but I don't really know how many strips I can drive in this method and it also seems that this duino doesn't have enough bang to drive the 180mA either. And moreover I probably couldn't hook Eth Shild to Rainbowduino anyway. I'd like this to be Ethernet based.
There must be some other good options too, please give me some pointers.
