Don’t tell the rabid Apple freaks, but the Magic Trackpad is flawed. Really, it is. There is no reason why it should be AA-powered only. A USB option would be awful nice seeing as it might never leave some users desks. But you know what they say, necessity is the mother of innovation. That’s where this bit of DIY engineer comes in. All you need is a wooden dowel, two screws, a bit of wire,  a USB cable, and an extra $70 if you mess up.

The skinny here is that you’re going to strip the USB cable and connect the hot and ground wires to screws on the end of the dowel. That’s about it. There’s no need to hack open your Magic Trackpad. Easy-peasy-lemon-squeezy.  [MacRumor Forums via Hack-a-day]
