Some people must really cherish grabbing every Achievement and Gamer point from every game. And with Microsoft promising rewards for such obsessions, who could blame them? Diego K. wanted to nab the 60 points for playing 1,000 multiplayer deathmatch games and 1,000 DarkOps games (30 points @) in Rare's Perfect Dark Zero, but obviously didn't want to sit there pushing buttons. So he built a robot to do the job for him.

With an erector set, a couple of solenoids, some other electronic stuff, and time to waste, he built the xBot (not the pejorative term), which automates the process of getting those 60 points for him. His full description of how the thing works can be found at the source (Read link), but what it does is simply presses the Start and B buttons at timed intervals, as demoed by his video below.
