Touch screen project

Postby stevenfalco » Fri Sep 13, 2013 1:48 am

The touch screen unit currently shown on the main wandboard page is my project. You can see the
initial posting here:

For the photo, the unit was running the prebuilt Android multi-touch demo software. My goal is
to get Fedora running on the unit. I plan to add an audio amp and speakers, and basically build a
very sophisticated "clock radio". Think a "super Chumby", and you'll have the right concept.

Thanks Steven... Yours was one of the projects I'd found most interesting - especially the case/cabinet...

How did you make this cabinet, i.e., how is the plexiglass cabinet put together? Was it glued?

Time for V2

I decided I needed better sound, so I created a new version of my touchscreen project. It is again constructed of 1/4" plexiglas.
Here is a front view.

The pushbuttons are implemented as plexiglas rods that run through a guide block to depress the tact switches on the
Future Electronics adapter board.

Here is a side view showing the volume knob, headphone jack, and power connector. These items are all contained on a
custom amplifier board I designed.

Here is the rear view. At the top are the speaker compartments, which are filled with fiberglas insulation. On the left,
you can see the WiFi connection, and the serial port, brought out on a ribbon cable. Guess I voided my warranty by
removing the 9-pin jack from the Wand PCB. :-)

On the right is the custom board I built, with a TI amplifier chip, regulators, etc. I left the back plexiglas cover clear
so as to show off the "guts".

The USB debug cable for Android can be seen exiting at the bottom. Now all I have to do is get my apps working.

This isn't my success, nor am I responsible for it, but I thought this should be posted here.
Lakka is an Emulator console that works surprising well on the wandboard even on thing like N64 roms.
There is also a prebuilt img available. (as well as for other SoCs)
