I have no idea why no one has made a ready to go out of the box kit for this. I myself would buy one and I'm sure others would too. It's an Untapped market which I'm sure has huge potential. I have 3 tv's I would love this on.. But these guides are just so confusing for me. I wish a simple clean DIY step for step was made. if these were being sold in best buy's or frys I'm sure lots of people would like them.

Sure, duh sorry, I'm using the lightstream PDE from https://github.com/adafruit/Adalight/blob/master/Arduino/LEDstream/LEDstream.pde
You can find my boblight config at http://pastebin.com/RkZsT6V9
I basically just used duct tape to hold the lights in place...works pretty good so far
Oh, I should add that this layout assumes you are starting at the rightmost lower corner.

I'm using a Uno and getting some pretty sporadic lights in strange places.
Will try your config tonight.

Got it working with your config file also. Thnx.

So "any" Arduino board with USB will do?
Nano, UNO, ... which one?

UNO works but is limited to two outputs, mega has 4. Just got my setup running with my mega last night.
4 outputs is nice but I was wondering if I could get more using shift registers or something similar. Any ideas?

What means is limited to two outputs?
Which impact has this on the configuration or setup of the ambilight?
Sorry I'm a Arduino noob :-)

Boblight uses the PWM outputs on the arduino. UNO has 6, mega has 14 I think. Each output is designated a color (red, green and blue). A single rgb led or strip requires 3 of these outputs (1 for each color), therefor the UNO needs 6 PWM outputs to control 2 LEDs or strips and mega needs 12 PWMs to control 4.

Sorry, one further question.
How many (WS2801 or whatever driven) LEDs can I connect via one stripe?
So let's say if I can connect e.g. 100 LEDs to an UNO and control them, why should I go and get a MEGA?
Sorry I'm dumb. :-(

It's all about the channels.
The max amount of channels is limited, so more channels mean a more realistic effect.
Beside that, yes you can use as many LEDs as you want.
As long as you drive them with enough power.
