I've actually always wanted to build some helpful devices for people with disabilities, I know that sounds completely different than the stuff I usually do (you know, like Xbox laptops and ghost documentaries) but I see it as an interesting challenge. Here was my chance!

I managed to get both rumble controllers on this thing because I didn't want to accidentally build a Sixaxis. The right analog shoulder button has been moved down and flipped for use with the pinky finger. The X Y B A triggers, along with right bumper, have been rewired with tact switches to the middle for actuation by the middle and ring fingers. The left analog trigger and left bumper have not been moved. It will take some getting used to but everything is within reach. Pulling the right trigger with the pinky isn't that hard, though who knows after a marathon of Oblivion rat-killing what could happen.

One of the biggest challenges, at least in the brainstorming "how I am going to do this?" phase was how to do the right analog stick. Then I realized I could just put it on the bottom of the controller and reverse its wiring. You don't actually tilt the controller on the axis of the stick because that would be awkward. (Believe me, I tried) Instead you actually just move the whole thing in the direction you want for the right stick, and the analog stick then rotates against your leg. This is why you have to reverse the wiring, because the use of the stick itself has been reversed.
