It looks more like an Xbox controller on critical-condition life support than anything else, but if you're going to do something so already frivolous as whip up a system to allow you to remote control your original Xbox from your PSP or DS, you might as well do it one of the most complicated ways possible -- mechanically (as opposed to electrically). Then again, this hack works not only on the Xbox controller, but just about any controller you can throw at it. Proceed at your own risk of though, we will not take responsibility if your innocent DIY project learns how to play and outgames you LEGO-gamebot style.
