More ambient lighting monitor hacks

[Christian Pigeon's] first big project was to build this ambient light system for his computer monitor. This is based on the same concept as the Phillips Ambilight system which illuminates the area behind a television to match the color on the edges of the screen. We’ve seen clones before, but this is the first one we’ve come across based on Amblone.

With Amblone as a starting point [Christian] modified the code to work with the Arduino Duemilanove which has fewer PWM channels than its bigger brother, the Arduino Mega. No word on where he acquired the RGB LED strips that provide the illumination, but the driver boards are just protoboard with groups of resistors and transistors to switch the diodes on and off. Check out the video after the break to see effects he achieves with this setup.

Phillips AmbX dissected

Electrosthetics has taken it upon themselves to open up and explore the insides of a Phillips AmbX system. The unit is supposed to help immerse you in your video games by adding ambient lighting, vibration, and wind. They got the starter kit, which is missing some bits. Interestingly they found that the hardware was not hampered in any way. You could plug in fans and such and, in theory, build the larger kit. There are lots of pics of the various pieces for you to look at. They note that the hardware all seems decent, but it’s the software that really causes issue. On their Vista64 dual core machine, the software was eating up an entire core to do ambient lighting.
