Boblight, Wylight -> Ambilight

For a long time the ambilight feature was on our list. We always believed the WyLight is capable to be used as a responsive ambilight, but we actually never did it for real.
Two weeks ago, was the right time to try it. So I did a quick search on google for 'linux ambilight' and I instantly found boblight
From the first moment it made a good impression. No hidden download, the code compiled without issues and the config files are easy to navigate.

Within minutes the boblight daemon is prepared:

svn checkout http://boblight.googlecode.com/svn/trunk/  boblight-read-only
cd boblight-read-only/
./configure
make
sudo make install

See the original docu at https://code.google.com/p/boblight/wiki/Compiling

Boblight supports different types of target devices.
We used the 'popen' type. For such devices, the boblight daemon is configured to run an executable and send RGB float values to the standard input of the created process.
This interface made it very easy to write such an executable which reads three floats from stdin, convert them to WyLight rgb values and push them to the WyLight.

You find an example boblight.conf in our GitHub Repository
For a first test all you have to do is change the 'output' line according to your own setup:

output /home/WyLight/boblight/bobwylight.bin    192.168.101.38

To create the bobwylight.bin:

# clone the WyLight repository
git clone git@github.com:polybassa/WyLight.git
cd WyLight/

# build the WyLight control library
make library

# build the bobwylight wrapper executable
cd boblight/
make

That's it! Your WyLight just became an ambilight!
Test it yourself and run:

boblight-constant FF0000
boblight-constant 00FF00
boblight-constant 0000FF

Now, you can use 'boblight-X11' to enable your ambilight

boblight-X11

See 'boblight-X11 -help' for details
