First of all, I'm passionate about electronics, but that's just like a football fan saying he's passionate about the sport but can't actually play. I'm a programmer, so since I'm on the tech side I can get pretty ambitious, but I do need your help.
I have the Kinect with the crazy proprietary cable and no adapter. I can hack it or just buy the adapter from Microsoft to use it with my laptop, but I want to be able to use it without keeping the Kinect plugged in a socket in wall.
The Kinect needs 12v, 2A. Some people reported it should work with 1.5A as well. I found this question that should sort out the voltage problem, but there's no way I can get 1.5A, is it? Get 12 volt power supply from Dell Laptop
Ideally I'd like to be able to power the Kinect from the laptop (I realize that would drain the battery very quickly) but alternatives are welcomed. I suppose a battery pack would do as well, but it would be great if I could avoid paying $40 for one...
How do you think these guys pulled it off? http://www.kinecthacks.com/navi-%E2%80%93-a-kinect-powered-vision-aid/
