So I got the display and stuff working. It is running a small 5" lcd panel shoved into the frame of the travel etch a sketch.
There's a small 0.5" gap along one edge, but I think it'll be ok. The slightly larger panels cost about $100 more, I don't think it's worth it.
I'll post a video of the whole thing working in the next few days. Next I have to dig out the 6dof imu board I bought ages ago but never got around to using for the balancing bot idea I had.
