[Chaos in a Can]

Based on messing with one today for a couple of hours, it seems to auto-calibrate when it is connected.
Unfortunately, it seems to auto-calibrate off center.

The closest I got to making it work was to hold the joystick off center and plug it in so that when I let it go back to center, the values were closer to 127.

After opening it up and messing with it some more, I'd say it's not worth trying to use.
