Step 7Making the output cable
The process for making the output cable depends on what adapter you choose for your projects. This step covers how to incorporate a USB mini-B male cable, since it's a common power plug format. I used a cable that came from a dead MP3 player and had USB-A male and mini-B male ends.
Cut the cable about 5 inches from the tip of the mini-B end. Strip the USB-A end and the 4 wires inside. To determine which wires are the positive and ground, plug the USB-A into a powered USB jack. Test combinations of wires with a voltmeter - if there are red and black wires, they probably provide positive power and ground, respectively.
Strip the outer insulator on the mini-B end about 1/4 inch. Once you know which wires are positive and ground, J1(+) and J1(-), strip these wires in the mini-B end and trim the remaining two wires.
