Bending should be possible, but keep in mind that the buttons we use have 4 solder joints at the corners. I don't know how easily they break when bending the PCB. But if you glue the bent PCB on a rounded stiff substrate it could work well. You could try a company like Leiton (they have an online shop for such flex PCBs): http://www.leiton.de/flex-pcb.html > - what are the dimensions of the PCB? how thick should the whole keyboard be > with the buttons included? The dimensions are following the current battery cover. I.e. it is 50x109 mm. The radius of the "ears" is 25mm. I.e. you can think of a 50x59 mm rectangle with two 25mm radius half-circles. But this is just the prototype and making a different keyboard PCB should not be a major challenge... The thickness is 1mm for the PCB and the buttons are Panasonic EVQPQ series (because they are easily available @ DigiKey): http://industrial.panasonic.com/www-data/pdf/ATK/ATKCE1.pdf Thickness is 0.55 mm. I.e. the total thickness is 1.55mm + any mechanics from housing. Hope this answers some questions...

A browser window of 480x480 + 160x480 for the keyboard is often more handy than a larger keyboard of 160x640 and 320x640 left over for the application.

Lacking reliable rotation on Freerunner, I must admit I have not often used applications in landscape; I remember some coping well, others not adjusting to the wider screen. > 4) perhaps your battery will fall out (if not secured with something) in > a lot of cases, esp. if it is the most important situation :-) ..cases, no pun intended? ;-) I guess we can come up with this securing something for the battery as well.

Maybe we can just copy motorola backflip - check videos on youtube, it has big keyboard on the backside - it looks very comfortable and mechanically one of the easier solutions.

If you move the battery inside the keyboard part and make the hinge a bit bigger, you could use it as a screen protector if you fold the keyboard in front of the display. And if you fold it the otherway, it could fit in what currently is the battery area. Just my 2 cents..

The idea is that the keyboard is integrated in the back battery cover. And if you remove it, both parts (main body and battery cover/keyboard) are connected through a small ribbon cable. I.e. you remove the keyboard, fold it by 180 degrees so that the keys show in the same direction as the display and you can us the display in landscape format. If that works out with the snap mechanism of the battery cover and/or if it needs some physical connection between both parts has to be worked out. A complete alternative could be a battery cover with a hinge.

Re: [Gta04-owner] [ANN] GTA04 Keyboard prototype
Hello, I have been thinking for a while to try a forearm-mounting casing for the openmoko. A casing that you would clip on the left (or right) forearm, that would be thin enough to fit under the sleeves or even covered with a piece of nice fabric to look like a cloth. This keyboard would probably fit well on the forearm together with the screen and it would make the whole thing easier to use. I am also thinking to place the antenna on the outside of the arm, above a piece of aluminum foil in order to reflect the radiated power and to protect the user from RF field. At the moment I don't have the GTA04, but I can make some rough drawings from the CAD files (I will need to download them). Would there be other people interested in this new way of carring your phone? I previously had some positive comments on the forum about this, so I think we could probably start a small group if there is enough interest. About the announcement itself, I think it is always good to show new ideas at early stages. This makes it possible for the community to orient the development of the project if they see better/different ways to use it. It also shows the level of interest.
