[Zach] is a huge Star Wars fan, and in addition to the array holiday decorations that adorn his house, he says that his wife is nice enough to let him put up a Christmas tree full of Star Wars ornaments. For the past few years, the tree sat in the corner of the room unlit, but his wife thought that it should have some lights this year.
His wife came home with a small string of battery-operated lights, but [Zach] wanted something with a bit more geek cred. He decided to program the lights to play the Star Wars theme song, translating the tune’s pitch to light intensity.
He dug through his bin of electronics and found an MSP430 along with a small target board that would do the job nicely. He sat down with some sheet music, translating the notes to PWM values, resulting in the light show you see below.
While his wife provided a lovely violin accompaniment to the tree, we think that a small audio module would make a great addition to the tree next year.

XDA forum member [craigbru] wanted to beef up the audio setup in his Jeep, and thought that his Nook Color would make a suitable replacement. Since he jailbroke the e-reader, the head unit upgrade lets him do just about anything you can imagine, all from the comfort of the driver’s seat.
Seeing that he would continue to go off-road with the Jeep, he wanted to construct a mounting solution that was convenient and sturdy – something we think he did very well.
The dock was constructed using a Quadratec iVault stereo mount, along with a plastic tablet mount he had on hand. Because convenience was a primary goal, he put together a quick release charging solution as well as a simple audio interface using a set of touch contacts. This allows him to connect and detach the tablet from the Jeep without having to fuss with a bunch of cables each time. He also added an audio equalizer along with a Bluetooth OBDII interface to the setup, allowing him to tweak his tunes and monitor his engine with ease.
We think it’s a great-looking setup, and we’d be lying if we said we didn’t want one as well.
