For now, our project seems complete once Xavier finishes building a case for the display and hardware. I can't think of a good way to make a controller using the joystick; the "Nintendo Wii Nunchuck" seems to be the best design for use with one hand. While my family is willing to lend one for the project, I'd have to make an adapter in addition to learning how it works.
For now, I am attempting to implement an Nunchuck based on Tod E. Kurt's "WiichuckDemo." This guy made an easy to use library for the Nunchuck.
In the future, I really hope that I would be able to use the Nunchuck and possibly program other things besides Tactile Tic Tac Toe. The Nunchuck is extremely versatile; not only does it have a joystick and two buttons, but also an accelerometer! Only now am I able to see the possibilities! Simon says? Wack-a-mole?
Battery background info:
A fire breathing pony operated by nunchuck I found that I just had to post:
Believe me, this has nothing to do with my little pony addiction (see what I did there?). Anyways, Hasbro and FurReal are completely different; I'm interested in Hasbro's colorful ponies. I completely accept the destruction of that pony. It was just cool.
