[Andrei Istodorescu] has been hard at work building a 7″ touch-screen rig which runs XBMC. It may be upside-down, but the Raspberry Pi board which is front and center is still easily recognizable. There’s a lot of stuff connected to it in order to pull this off, and even more software configuration. But as you can see in the clip after the break he did get it working!
The screen is an eGalaxy 7″ touch sensitive module he picked up on eBay. It sounds like it was meant for a backup camera in the dashboard of a car. He compiled his own Linux kernel to add support for the screen. It uses HDMI for the video interface with the driver board, and the touchscreen connects to one of the USB ports. The rest of the setup involves compiling XBMC with touchscreen support and calibrating the screen to accurately sense input.

Nice build. What’s the estimated cost of the whole thing?
The post isn’t exactly clear about that, but here’s a parts breakdown:
1) 7″ Display with resistive touchscreen (~$60 and higher)
2) Some kind of HDMI to LVDS converter (Price unknown)
3) 4 wire resistive touchscreen controller to USB (~$20)
In the post, below the pictue, you can see the estimated price, which was, at the momemnt of building:
30$(Raspberry PI) + 80$(display with touchscreen and touchscreen controller) + 2$(hdmi to hdmi) = 112$.
You should add the SD card(which I don’t know how much it costs) and the power adaptors(which I also don’t know how much they cost). I already had these parts around my house.

Got it working right out of the box.
Yes, but this will not work with XBMC on Raspberry PI, unless you build XBMC with my patches.
I got that exact hdmi display, touchscreen controller and hdmi display pcb from a Chinese eBay seller for about 36 GBP delivered.
The resolution is low but quality is okay if not a bit washed out. I’m in the process of coming up with an enclosure because it’s very delicate with those ribbon cables.
I used a 0.15m hdmi cable from cpc (Farnell) instead of the coupler.
The touchscreen worked well on windows so I’m glad to see someone got it working on the pi
let me know what you did for enclosure. i am trying to figure something out myself
I love XMBC but am looking for recommendations on touchscreen compatible skins…. I know there are a lot out there, but am looking for one that is really good.
Also sidenote…. whats the best way to use XBMC as a home jukebox (while still having XBMC remote work)
The touch screen controller is eGalax, not eGalaxy.

Andrei
I have almost the same parts to make almost the same thing :) I’ll have to improvise to make it to hackaday ;)
show!
You could use something like this for Home Automation, have a Raspberry PI mounted to the back of the screen, and build this into a wall, to control lights, home audio and a bunch of other things – Might be something I may try….
This is a great idea – Gave me a idea to use this in a Home Automation install, having the Raspberry PI mounted to the rear of the screen, and coding it to activate things like lights, music, heating…. possibilities are endless.
Could you post how he modifyd the kernel?
