eeePC Touchscreen!

by on Jul.18, 2009, under Computers, fun, Linux, Mobile

So as some of you may know already, I bought an eeePC, for fun and to mess around with.  Well my latest fun with it was adding a touchscreen, and adding internal bluetooth!

Well, I purchased the Hoda Technology 8.9″ Solderless Easy and Fun TouchKit Touch Screen Kit, which came with a touchscreen, the controller board (with added USB hub) and the wires to connect it solderlessly to a internal USB header (I had one as I do not have a built-in cam, though even if you do, you can still use this!)

— The following pictures and more are available in my gallery —

Below is a quick guide on what I did to add in the touchscreen:

Included parts in the touchscreen kit

Here is the contents from the kit, included a dual pen/stylus!

Netbook taken apart Netbook taken apart

First I took apart my machine following the many guides to make sure I did not break anything I shouldn’t.

Finding a smooth path for wires

Next I tried to find the best path for the wires to go, without making new holes or pinching the wires.

JST SR04 and JST SR05 Connectors JST SR Jack removed Correct pinout for JST SR04 Connection

Whoops, the included wire to go from the controller to the motherboard is too short for where I am placing the controller.  Time to make a mod to the mod!  I had to very carefully take apart the JST SR04 jack and swap it with a longer wire.  Good thing they provided all the needed parts. Note the correct pin layout to make sure its recognized (the included cable had the pinout backwards!)

USR bluetooth adapter

Next, the bluetooth adapter.  The kit also had two JST SR05 to USB connector. After removing the plastic housing to my already small bluetooth adapter, I could easily fit it inside the case. Now I have all 3 external USB adapters free again, and nothing to forget or lose. Now I can tether to my cell and still look cool!

Fitting the touchscreen.  This was a PITA to get correctly centered, but I got it eventually.

Turn Camera on in BIOS Linux dmesg

After putting everything back togeather, I had to first turn the “camera” port on in the BIOS, then Fedora recognized the controller and USB devices on boot!

Now, even though I am running Fedora 11, which has support for just about every product under the sun, I still had to install drivers for the controllers, which was easier done then said.

First, I had to make a generic Xorg config, as Fedora does not make one now (its made on the fly)

[root@localhost ~]# Xorg -configure :1
~~ some output from Xorg ~~
Your xorg.conf file is /root/xorg.conf.new

To test the server, run 'X -config /root/xorg.conf.new'
[root@localhost ~]# mv xorg.conf.new /etc/X11/xorg.conf 

Second I had to download and install the latest (2.06.2905 [beta]) drivers from the website [Local Copy of Drivers].

Then extract, and run the setup utility:

[root@localhost ~]# cd /tmp/
[root@localhost tmp]# tar xzvf ~drdelaney/Download/eGalaxTouch-2.06.2905-32b-k26.tar.gz
eGalaxTouch32/Guide/How to rebuild kernel.pdf
eGalaxTouch32/Guide/How to build module.pdf
eGalaxTouch32/Guide/Driver Guide.pdf
[root@localhost tmp]# cd eGalaxTouch32/
[root@localhost eGalaxTouch32]# sh ./setup.sh
