I have started gathering/building everything i need to achieve this. just built my 'power board' for my leds baased on the Amblone arduino board. I am waiting for my led strips to come from china ($60 each is aus).
I was able to test just a small section of the screen with a 10cm strip on boblight but it seems to react to the screen nicely.

Here is my board.
Im grabbing 12v from htpc
Bottom headers are outputs to led
Side headers are inputs from arduino mega
Added a switch to turn light on and off
Added a led to tell me if its on or off (because i can )

BTW, i have no idea if im going about this the right way but from what ive been able to test it seems to work

This one is the same as in my tutorial http://forum.xbmc.org/showthread.php?tid...=Ambilight

I assume that you will use Arduino Mega.

Now this one is even easier to build because there is also a chip with transistors included so no need for too much soldering and even less soldering skills are required. It replaces transistors and resistors.

There is the schema http://fritzing.org/projects/uln2003a-amblone/
The chip is ULN2003A and you need two for four channels. It is available on eBay.
