Boblight is a collection of tools to control rgb lights hooked up to a computer, its primary goal is to create an ambilight system.

Boblight consists of 5 programs:

boblightd

Boblightd is a daemon that controls lights bases on input from clients over udp, it supports two rs232 based protocols, it can output a pwm signal with a soundcard (using alsa) and it can open a program with popen() for easy implementation of custom protocols.

boblight-X11

Boblight-X11 grabs pixels from an X11 screen and sends the average color to boblightd.

boblight-constant

Boblight-constant sends a single color to boblightd.

boblight-jack

Boblight-jack creates colors based on audio from jack, it's basically a light organ, the red color reacts to the lows, the green color reacts to the mids and the blue color reacts to the highs.

boblight-v4l

Boblight-v4l captures video from a video4linux device, you can connect the composite output from a tv to a tv card and make an ambilight system.

HOWTO: Add ambilight to your tv

It's impossible for me to test every single configuration or to get every bug out, writing documentation is also a lot of work. I am willing to help you set things up, use the contact link on the left.
