* A 5x15 keyboard
This is a keyboard project. That's also my first hardware project, so
in case if somebody would want to reuse it, be careful. Though I've
built it and it works.

The keyboard has 5 rows and 15 columns (well, depends on how one
counts, but approximately that much), and intended to be handy for
emacs: has plenty of accessible modifier keys, and never requires to
get too far from the home row.

More information, photos, and the build process description can be
found in the "[[https://defanor.uberspace.net/notes/building-a-keyboard.xhtml][building a keyboard]]" note.

** Dependencies and software
The switches are borrowed from [[https://www.ergodox.io/][ergodox]] (and altered a bit), and the
[[https://github.com/LuisDiazUgena/Teensy-3.1][LuisDiazUgena/Teensy-3.1]] library for kicad is used. KiCad and LibreCAD
were used, by the way.

For the firmware, I've used PaulStoffregen/{[[https://github.com/PaulStoffregen/cores][cores]],
[[https://github.com/PaulStoffregen/teensy_loader_cli][teensy_loader_cli]]}. Changes introduced to ~teensy3/Makefile~:

#+BEGIN_EXAMPLE
 # configurable options
-OPTIONS = -DF_CPU=48000000 -DUSB_SERIAL -DLAYOUT_US_ENGLISH -DUSING_MAKEFILE
+OPTIONS = -DF_CPU=48000000 -DUSB_KEYBOARDONLY -DLAYOUT_US_ENGLISH -DUSING_MAKEFILE
#+END_EXAMPLE

Then it can be built with ~NO_ARDUINO=1 make~.

Hopefully without violating licenses of the reused bits, this project
is GPL-licensed.
