We’ve seen a few clones of the Philips ambilight tech, but [Phil] knocked this one out of the park. The hardware is a string of 12mm RGB LEDs connected to the Arduino of your choosing. After attaching the LEDs to the rear of the TV using anything from, “laser-cut acrylic to nothing more than a pizza box,” it’s on to the software.
The Processing sketch performs a series of screen captures and averages the pixels around the perimeter of the screen. Reportedly, Carl Sagan’s Cosmos looks fantastic with the Adalight but there might be a better option.
[Phil] used 25 LEDs on his Adalight, more than the usual 6-10 we see on other Ambilight clones. Check out the video after the break to see the Adalight in action.
