Software

Installation

1. clone my fork of qmk_firmware
2. cd qmk_firmware/
3. Grab the chibios submodules: git submodule sync —recursive && git submodule update --init —recursive
4. open up qmk msys
5. qmk compile -kb bakekujira -km default -bl dfu-util-split-left (do the right side also, you only have to do this once for each side)

Notes

• onigaku repo (not included in this repo) has all symbols and footprints
• Sorry for not using Kanji, thought Kana had a better overall fit!
• The art design is temporary. I will be changing the mascot to something easier on the eyes.

Suggestions

• Order more than you need of the diodes, caps, and leds, and kailh sockets. FYI, in most cases there is a MOQ
• The 01.uF capacitors aren't absolutely needed, but it will help with fluctuations and possibly prevent LEDs from burning out.

Soldering Hints

• It's easier to use a wider/bigger tip in some cases.
• For the small solder pads, make sure you are tinning and using flux to ensure that the very tip of your soldering tip will hold a bead of solder.
• For the Kailh sockets, you can put solder on both pads first and then pushing down on the kailh socket while heating up the ends one at time.

LEDs

• When soldering the underglow LEDs, bend the terminals/legs down so they touch the soldering pads.
• Solder the LEDs in the order that wired up and test as you go. Please see the diagram (ie solder the under glows first)
• If the LED looks broken or melted, it's probably broken.

Inspiration

Picked apart a lot of boards, including:

• Corne
• Corne Waffle
• marevelous65 split
• ganymede

TODO

• build case
• build plate
• working out breakout board for 256x32 (see other SSD1326 breakout repo)

REV2

• move proton-c and plugs out instead of tucked in line with the top row to allow for more case options
• Add holes for M2x4 or M2x9 screws/standoffs to allow for more case options
• sound and speakers
• oled 256x32, which may end up here under rev1
