I know I can buy one, but I'd like to build my own. I have the newest edition GP2X, so I can supply the 5V power straight from the EXT port. I just want a cable that I can connect either a flash drive or maybe a wifi stick or something to it. I know it'll use power fast by having the 5V supplied by the GP2X, but that's fine with me. Is there maybe some sort of tutorial on doing this, or some kind of instructions? Thanks!
