Overview
The Quirkey is designed for use by people who cannot use a conventional keyboard because of limited mobility or vision. It uses just 6 microswitches to emulate a full 101-key keyboard and mouse without removing any digit from over its key. As the pressure is applied by the finger pad and not the finger tip, it can be used by people with brittle bones, or joint dislocation disorders etc. The hand can be strapped to the keyboard for users with tremors. As it is not necessary to look at the Quirkey while using it, it can be used by people who have to lie down, or cannot see at all.
It is also useful for people who need to look at other things while entering data, observations, live blogging, in Virtual Reality etc. or simply have a shortage of desk space.
There is a V4 design by the same author that uses standard MX Cherry-type keyswitches, which seem to be more readily available these days.
Assembly
Full assembly instructions are in the file list. All parts print without support, though there are two break-away vanes inside the shell that should just snap out easily. The electronics needed are simple: 6 microswitches (lever, 12.8x7.5x5.8mm like DM1-01P-30-3 etc. 100,000+ cycle life) and either a Pi Pico or Arduino Leonardo mini compatible. If you are physically unable to assemble one, contact your local makerspace or the author (who sells these things complete).
Source Code
Code and full user documentation to learn how to use the device can be found at https://github.com/VikOlliver/Quirkey and the OpenSCAD source files are at https://github.com/VikOlliver/Quirkey_3D . The colour scheme suggested in the photo above is used in the tutorials, though once learned you can pop them out and put in whatever colour you like.
No driver software is needed when using the Quirkey with PC's, laptops, tablets, and mobile phones.
Downloading Files
The files for a left-hand design are prefixed with “left_” and you will need to print a shell, base, thumb key, command key, and 4 of the keycaps.
Designs are available in various sizes, and the microswitch size can be changed in the OpenSCAD source. Message the author and he will upload custom files here.
Bug Fixes
The first files released had the locating pin on the thumb key misaligned. Fixed 5-Dec-2023.
