Who knows why tech tinkerers do what they do. We're just happy to see those idle hands try the untested. Like this latest Arduino hack from modder Michael of Nootropic Design, who's seen fit to rig a 16 x 32 LED matrix up to an Android phone for use as a secondary display. The outputted video, downscaled via OpenCV software to an appropriate resolution and 12-bit color, is admittedly unimpressive, as it chugs along at a paltry four frames per second. But that's not the point of this can-do experiment -- it's all about the possibilities, however blurry and pointless they may be (although, we're sure Barbara Walters would beg to differ). Ready to see this modjob in motion? Then head on past the break for a brief video demo.
