Creators! Feel free to tip me off about your keyboard related projects to bring them to 100K readers.

Jason Allan aka @Drudge/jsallan shared the files of his flow-MX36, the first member of the flow product line. This is an MX-based keyboard, 36 keys with integrated trackball.

Hi folks, I’ve been working on this keyboard pretty much since January of this year, and I’ve finally got it to the point that I can call it done! If you’d like to build one, all files are available here – Jason.

The top design considerations of this keyboard series are:

  • proven comfort from previous split designs of the author, e.g. the MX Dacty-based Minidox and choc Trinidox
  • trackball mandatory for enhanced convenience
  • a finished look, e.g. hidden switches, smooth lines, hidden plate etc.



  • 36 keys
  • integrated 34mm trackball using the PMW3360 sensor
  • ceramic trackball bearings
  • options for both choc v1 switches and MX switches
  • USB-C interlink cable
  • trays for various microcontrollers – Pi Pico and Pro Micro (in dev)


The Github page has a bunch of details, part list with links and guild guides:
