I had a spare webcam which i turned it into a night vision camera. I have to use IR emitters to be able to see with it ( http://www.instructables.com/id/Night-Vision-Webcam/?ALLSTEPS ) and i don't want to use a tv remote for that. I was wondering if i could power the emitters (4 emitters actually) with the usb port and cable of the webcam? Could you tell me how or give me a suggestion or a link or something? Thanks!
(Btw, i can do some basic soldering and stuff too)
