Having already made a name for himself with system mods for the Wii like the internal GameCube memory card and the internal Wavebird receiver, hardware hacker foobar2k shifted his attention to the Wii remote for his latest creation: a USB Wii sensor bar.
There have been other homemade USB Wii sensor bars that take advantage of the remote's "pointing" functionality, but this project wins points for stuffing all of the LEDs and wiring into a pen case. If that doesn't sound classy enough for you, he also secured the bar to his monitor with Blu Tack and branded it by scrawling "Wii" on the casing, off-center.
Foobar2k has instructions and a photo guide at his site for creating your own USB Wii sensor bar with cheap and accessible materials. Let us know if you can think of any ways to make the setup even more ghetto than it already is.
