One of [Caleb]‘s side projects before he left us was TheControllerProject, a place for controller and console modders to hook up with gamers with disabilities. Things must be hopping over there, because [Caleb] just announced his first contest, with prizes, even.
The goal of this contest is to make the trigger buttons on XBox and PS3 controllers able to be controlled from the top of the controller. This is a huge problem for gamers with disabilities, and no open system currently exists to solve this problem. If you can make some sort of mechanical device to turn shoulder-mounted buttons into top-mounted actuators, just host it somewhere and win a prize.
The prizes are an iFixit toolkit and magnetic mat. The first five people to send in a solution to the shoulder mounted button problem get this prize. Originally, [Caleb] thought about tearing apart these controllers and soldering extra buttons, but a snap-on mechanical solution is much easier to install.
