[Garrett Mace] decided to beef up his 58 inches of plasma with 60 Watts of LED lighting. After seeing a ton of Ambilight clones using his LED modules, he’s built his own powerful system. Not surprisingly, it’s nothing short of professional-grade work.
Kudos to [Garrett] for showing the entire process in the video after the break. We’re talking about his planning stages, which are so often left out of build logs. He first measures the back of the television, and does some testing for distance and angle of the Satellite LED modules to establish how many should be used and to estimate the optimal spacing. From there he modelled a framing system before getting down to the actual build.
The wood frame is made up of a box with a horizontal crossbar serving as a place to mount the drivers. Around the edges, tilting rails were added to make the angle of the LED modules adjustable. As with many other Ambilight clones, [Garrett] uses the boblight software to drive his system and we appreciate it that he included his configuration file for reference. Once up and running the effect is breathtaking (and possibly blinding).

[Don] put together a guide that will help you build your own Ambilight Clone for about $40 plus the cost of an Arduino. He’s using it with the HTPC seen above, and utilized modular concepts in building it so that you can easily disconnect your Arduino board when you want to use it for prototyping.
For RGB light sources [Don] grabbed six ShiftBrite modules. These are fully addressable cascading modules which make for very easy hardware setup. Instead of buying a driver shield he built his own using an LM317, heat sink, and wall wart to source enough current to drive all of the modules.
We really enjoy the mounting scheme used. Each module is attached to a piece of acrylic which is then mounted using the standard threaded VESA mounting holes on the back of the monitor. As with other Ambilight clones this one uses the Boblight package to get color information from the video as it plays.
[SunWind] developed his own version of the Phillips Ambilight system (translated) which he is calling LiveLight. We’ve seen more than a few of these hacks, many of them are based around Arduino, and most use LED strip lighting. [SunWind] is using strip lighting as well, but his design is clean and polished quite a bit more than anything else we’ve seen. In our minds this would be welcomed by even the most discriminating of A/V enthusiasts.
He found just the right size of project box and managed to fit everything in on a nicely milled PCB. The enclosure itself has also been milled to allow the mini USB B connectors for each of the nine RGB LED strips. But he didn’t stop there, the top of the enclosure has labels milled into it to help when hooking everything up.
An ATmega32 addresses the LED strips based on data pushed in from a computer. An on-board FTDI chip adds USB connectivity and [SunWind] used a hack to rewrite the EEPROM on that chip so that it enumerates with the name “LiveLight USB Interface”. A program called Boblight gathers the data from the currently playing video. You can see the final project in the video embedded after the break.
