Could I make one out of MacBook parts? The trackpad and keyboard is usb on MacBooks MacBook's seem like it would be the easiest as the keyboard/ trackpad uses one cable that looks like it only has 4 wires in it and usb is 4 wires! If you just want to recommend not trying to build this just go away! I do not want any more people saying it would be easier to use a iPod touch or iPhone as I do not have one. I would love it if someone would post the MacBook trackpad / keyboard cable pinout. I need someone to give me the pinout of the MacBook keyboard / trackpad cable. If I had this I would know weather this would work or not and it would be very useful. It would also help if anybody has a MacBook (plastic) with a broken screen that they don't want that would be very helpful if you could try to connect it to usb cables once the pinout is posted. I already know it is USB so it is possible but I need the pinout before I can continue and I go and purchase a CD MB top case for some experimenting. If you want it wireless you can put a wireless usb hub inside it and a battery to make it wireless. If I build this out of PB parts I would finally have some motivation to get a new battery if I could make the PB battery work.
