This seems really nice! I added myself to the wishlist. Is the back cover keyboard 3D model available? I have a 3D printer currently being shipped to me and I would like to try to print the cover when the printer arrives. > > But watch yourself how we think it can look like: > > http://youtu.be/WM94%5fR5eKcc > > There is also a new video showing a comparison with some other keyboards: > > http://youtu.be/wGASnE1zGh4 > > Pleas tell us if you like this idea and what you would like to pay for such an > extension unit through the Wishlist function of our shop: > > http://www.handheld-linux.com/wiki.php?page=GTA04%3AKeyboard > > Two issues are still to be developed: > > a) how to reliably connect it to the GTA04 PCB (soldering copper wires or a > FFCs is a little difficult so it should have a tiny, flexible but robust > B2B cable). > > Maybe, we can use a micro-USB socket or similar (we need to connect 6 > wires). > This may also need a redesign of the GTA04 board (for a nice plug) > > b) design a 3D printable case with key-caps that is robust enough > > If you want to support us for developing this idea, please give us a kickstart > donation. > > > Nikolaus > > PS: the keyboard driver for the TCA8418 is already part of Linux 3.3 - and has > been backported to the 2.6.32-kernel.
