Keyboard of Disapproval ಠ_ಠ

First of all, I guess you wouldn't want to build your own keyboard,
but anyway, here it is:

In case anyone curious, it's built on scrap collected over 5 months, 2016 September - 2017 February, the plate is metal frame with 60% layout (GH60) from aliexpress, switches is gateron blue bought from Massdrop, the key caps is randomly bought from local gaming store, and the controller is arduino micro clone from Robotdyn.

The Name

Considering how much time, effort, and money poured on this, I don't think anyone will approve.
Also, naming is hard.

The Build

While the layout is totally GH60, this keyboard is somewhat built from scratch. The switches are all hand-wired with 8x8 matrix, so it's only use 16 pins. Matrix layout here. The firmware is written from scratch on top of LUFA (all USB related code was adapted from LUFA keyboard demo though). Currently there is only one base keymap, with [Fn] modifier to accomodate arrows, [pageUp]-[PageDown], [Esc], [Home]-[End], and [Insert]. (See todo below)

The Firmware

Please change the makefile according to your environment setup, run make to build the firmware. Run make avrdude to flash the firmware. Previously I plan to build the keyboard on ATTiny167 based Digispark Pro, but I scrapped the plan and go with ATMega32u4 instead. And this RobotDyn Arduino-Micro clone is dirt-cheap!

Todo

  • LEDs
  • More layers?
  • Special layer for input macro (shortcut to input some text)
  • Proper mounting/housing for the controller
