RasPi with Touchscreen

I’ve wanted to use my RasPi with a touchscreen interface for awhile now, and have finally starting collecting the information I need.  Here’s the first haul:

First, you’ll need a screen to interface with the RasPi. For simplicity, you’ll want to find one with HDMI input and USB interface for the touch layer.  Here are some good examples:

Example 7″ Screen      Example 8″ Screen

Next, you’ll need to be able to interface with the touch drivers. Here‘s a great write-up (including Kernel building and XBMC patches).

Note: In lieu of buying one of the kit screens, you can use an old laptop screens with DVI/VGA with one of these, and then buy a matching size touch overlay.

VGA Generation with Atmega644p

I’ve always wanted to try out video with a microcontroller, and this a great example project.  It will display a flicker free 256×240 256 color image stored in SRAM.  It seems like it would be a small step to take this from a static display to moving images.
