Cool! Back in 2012, I got impatient and put together my own resistive touch screen for the Raspberry Pi: https://www.youtube.com/watch?v=uwEwHFglq8M. I just got a small LCD, a resistive touch panel, soldered up a microcontroller, and wrote a simple kernel module (https://github.com/osandov/raspi/tree/master/tsc2007) to get it all working. Unfortunately, I never really got around to documenting how I did it, and it looks like this makes it obsolete, but it's all for the best :)
