Keyboard for GTA04
During the Openmoko Stammtisch Munich yesterday, we have once again discussed options to build a special GTA04 keyboard. And now I think we have found a way to really square the circle. The square being functionality and the circle being cost. The idea is to use: * off-the shelf pushbutons (Panasonic has some nice and very flat SMD buttons readily available at DigiKey) * a Shapeways made custom case * a not very sophisticated PCB with the buttons, a Bluetooth HCI module [1], a small LiIon battery and a microcontroller scanning the keyboard and supporting USB charging Now comes the key idea: having a shapeways printed case makes it possible to think about a keyboard built into a replacement battery cover. It makes it a little thicker than normal, but you can detach it and use it as a keyboard. A first cost estimate: * buttons: 25 ct each i.e. 16 EUR @ 64 keys * case: 20 EUR * bluetooth module: 20 EUR * PCB + MCU: 20 EUR * Battery, production etc. So it should be possible to build such a beast at less than 100 EUR (where we are back at the financial issues we generally have). And, it needs people working on it. Tasks will be to choose a HCI capable bluetooth module and a MCU, write software (firmware), work on the schematics develop 3D data for a Shapeways case. Who would be interested (and has time and skills to contribute) to join a team that starts working on such a project?

Re: [Gta04-owner] Keyboard for GTA04
Hi, Nicolaus, Actually detached keyboard is almost useless for phone. It is not possible to use it any conditions expect then phone lays on some surface and you not holding it. This is because if you using one hand to hold phone, you have one one hand free. Holding and using keyboard with one hand is not possible. Before implementing such detached keyboard, buy bluetooth one in shop and try it - you'll find it completely useless :) So, keyboard on phone should be build-in and usable... and i don't know how should look something better than keyboard on n900. If gta04 have hw keyboard, i buy it immediately as a every-day phone. Linux has excellent set of command-line tools and it's a crime not to have a hw keyboard on linux device.

Yes it's better than onscreen keyboard but being able to attach it to phone is the important part at least for me.

Something like double battery cover with some rails for keyboard sliding out from it would be nice (still holding one piece of hw - even if it makes whole phone extra 1cm thick).

Re: [Gta04-owner] Keyboard for GTA04
Hey, I would like to have it rather swinging out than sliding. Then you could lock it at ca. 180° (with a bar or something) and by using the full back area of the case, it would be big enough for a expanded layout. As connector I would like USB more than bluetooth, but don't know how thin a cable can be.

My main concern are that cables may break too often and connecting it to the main board plus getting it out of the device is a little fiddly. I agree that's probably the trickiest bit. Any idea how sensitive the i2c is to the cable? Would a flexible headphone lead type work, or would it need flexi-pcb? But this could be a cheaper (and easier to develop) option than BT+Battery.

Re: Keyboard for GTA04
Hi, my idea would be a very stable leather case for the GTA4. I would attach a bluetooth keyboard to the cover, that the keyboard opposes the screen, if closed. The leather case should stable enough, that if it is open, you hold it with both hands, and type with your thumbs, while looking on your GTA4 in landscape mode. Kind of the same concept as the clamshell Zauruses. The bluetooth conection has the advantage, that you can bend it a thousand times, it will not break, like cables. But ... the keyboard needs its own battery. only an idea, Joerg On Thu, 2012-03-15 at 15:30 +0100, Dr. H.

That way we wouldn't need bluetooth or a battery, nor have to connect new cables to the main board. Additionally, it would make it easier for people who prefer a thinner phone and don't mind carrying extra devices, as they can use the standard back cover and still be able to connect this keyboard. Also, if we use a standard USB keyboard module (I don't know if that's feasible), it could be tested and used with other PCs too... Of course, it does have a downside - can't use the USB port while the keyboard is connected (unless it includes a hub and/or charger passthrough), and is arguably riskier wrt. destroying the USB port if you drop the phone with the keyboard connected... -- Regards, Frode Austvik ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
