The Dactyl-ManuForm Keyboard

This is a fork of the Dactyl, a parameterized, split-hand, concave, columnar, ergonomic keyboard.

The main change is that the thumb cluster was adapted from the ManuForm keyboard (geekhack). The walls were changed to just drop to the floor. The keyboard is paramaterized to allow either 4, 5, or 6 main rows. I plan to try the four-row version. See the following model files:

• 4 rows
• 5 rows
• 6 rows

This is still a work in progress.

I plan to use a Teensy 2++ in each half. Then, I have enough channels to wire straight to each key switch. Diodes are not needed. Then, I can connect them with a serial connection, and adapt the QMK firmware for the Let's split keyboard that implements this approach. Each half can be master.

This doesn't have a bottom. I may or may not add one. I have many test prints to try.

Assembly

Generating a Design

Setting up the Clojure environment

• Install the Clojure runtime
• Install the Leiningen project manager
• Install OpenSCAD

Generating the design

• Run lein repl
• Load the file (load-file "src/dactyl_keyboard/dactyl.clj")
• This will regenerate the things/*.scad files
• Use OpenSCAD to open a .scad file.
• Make changes to design, repeat load-file, OpenSCAD will watch for changes and rerender.
• When done, use OpenSCAD to export STL files

Tips

• Some other ways to evaluate the clojure design file
• Example designing with clojure

Printing

Pregenerated STL files are available in the things/ directory.

Wiring

Masks for the flexible PCBs I used are available for the left and right side.

A very rough guide for the brave is here - It will be improved over time (TODO)!
