In 2011, [Fabio] had been working behind a keyboard for about a decade when he started noticing wrist pain. This is a common long-term injury for people at desk jobs, but rather than buy an ergonomic keyboard he decided that none of the commercial offerings had all of the features he needed. Instead, he set out on a five-year journey to build the perfect ergonomic keyboard.
Part of the problem with other solutions was that no keyboards could be left in Dvorak (a keyboard layout [Fabio] finds improves his typing speed) after rebooting the computer, and Arduino-based solutions would not make themselves available to the computer’s BIOS. Luckily he found the LUFA keyboard library, and then was able to salvage a PCB from another keyboard. From there, he programmed everything on a Teensy microcontroller, added an OLED screen, and soldered it all together (including a set of Cherry MX switches).
Of course, the build wasn’t truly complete until recently, when a custom two-part case was 3D printed. The build quality and attention to detail in this project is impressive, and if you want to roll out your own [Fabio] has made all of the CAD files and software available. Should you wish to incorporate some of his designs into other types of specialized keyboards, there are some ideas floating around that will surely improve your typing or workflow.
