After spending too much time browsing this subforum and loving the look of Mr Bishop's Pawn and the Gherkin, I decided to have a crack at a mini dvorak keyboard to use with my phone or Surface Pro.
Layout is here if you want to play around with it.
linkUsing the two function keys either side of the spacebar to switch layers, with the layout based on the dvorak Flesky android keyboard layout that I use on my phone. If I can get a trader on Aliexpress to send me one, I might add a flexpoint pointing stick mouse, and use the keys either side of the up arrow on the second function layer as right and left mouse click,
Fortunately I'm a Fablab technician so making the faceplate and case should be a breeze. Will probably prototype it out of plywood and acrylic but will probably make the final one out of CNC milled wood and either aluminium and copper.
