I saw another instructable on here a while ago about soldering a power cable directly to the board and i liked the idea of not using one of our micro usb cables for a permanent power solution. I found the gpio pinout online and decided to try to make another power cable but using parts i have all over the place. I ended up making two cables, a short one and a long one and it works great. Then to connect to the pins i modified a cd audio cable from a really old pc. you may not have one of these but i also found that you can connect an ide ribbon cable to the pins and that works as well. I read that this bypasses the fuse that protects the board from voltage spikes but im not worried about that. It works and im happy with it.
