diy usb problem Answered
hey i saw some videos on diy usb fan, thought it was a great idea, so i tried to make one too for fun
so i took my old broken logitech usb mouse and cut it open, however when i opened it i saw black, white, red, green, a string, and a copper wire - like the picture on the imageshack link (sorry for the blurr)
so i still only use the red and black wire right? and in what conditions should i not use the usb for powering (such as the product uses more than 500 milliamp?)
and just out of curiosity does any1 know whats that copper wire with no shielding is for?
