Here’s a video of it in action: https://www.youtube.com/watch?v=iDb8_ld9gOQ
I’ve been using it for almost two years now, and I’m not going back.
It’s based on a spare Blackberry Q10 keyboard and a custom Arduino-compatible board that reads the keyboard matrix and outputs it as USB HID to the phone. From the viewpoint of the phone, it’s just a regular USB keyboard, so no special software is needed.
But I do use a custom virtual keyboard to have just two rows of symbols that are not natively on the keyboard, as I didn’t want to add another layer of rarely used symbols that I’d have to memorize.
(On the image you can see Ubuntu with XFCE4 running on it. I chose Ubuntu because it’s what was easiest to get running in a chroot jail on the phone. I’m using VNC to display the GUI. I even managed to get FEX (x86/x64 emulator) and Wine running, so it runs x86/x64 Linux and Windows apps.)
Btw: Is there maybe someone who wants to make a little side money? There are tons of people who say they’d buy this, but I don’t want to make them.
The designs are all online and I’m happy to help. So if someone wants to make and sell them, that would be really cool! (I don’t want or need any financial compensation. I’d just be happy if people have access to this.)
Minimum order quantity for most of the device is 2, and it costs ~€40-50 per piece if you make 2 of them. If you make 10, this drops to ~€20-30 per piece. If you want to, I can link you up with some people that might be willing to pre-pay, so that you can get the funding to make an initial batch.
From what people told me, they’d be happy to pay €50-150 per piece, with most people being at €70-100.
Required skills would be soldering (same pitch as TQFN44) and 3D printing (PETG) for making them, and Blender or OpenSCAD for adapting the design files to other devices than the FP4.
