README
README.mdbully-files
Bully is a keyboard designed by paaradiso keyboard design and zhol. It combines low typing angle, a plateless build, and modest but dignified design sensibilities. Its 13.5u width layout is designed for maximum compatibility with base kits that are missing minimum 40% keyboard support (“3-key”). Bully has a 22.4mm EKH, 4.0 degree angle, and bezels measuring 8mm and 3mm.
The case files are provided in the ./case directory, and alternative tops for HHKB layout (1.25u blocker) and WKL (1.25u blocker) are provided in their respective directories.
This ran in a private run and public run by Coffee Break Keyboards in Q1 2023 and fulfilling Q2 2023.
Required components
- Daughterboard
- It is designed for C3 Unified Daughterboard, but an updated daughterboard that takes JST-SH cables is provided here.
- Tadpoles
- bully's PCB is fit into the case not with screws, but 8 injection molded rubber inserts named "tadpoles", from Geonworks.
- Files, courtesy Geon
- Screws
- All screws are M2. Screws for daughterboard are 4mm, case screws are 6-ish mm.
- JST cable
- As sold, bully took a 50mm 4-pin JST-SH cable. These cables are wired 1:1. I had no issues with Adafruit Qwiic JST SH cables sourced from Mouser. If you use an alternative connector on your PCB and daughterboard, you will need to ensure those cables are also 1:1.
- PCB
- Case feet.
- bully uses SKUF feet.

Questions
How big is the Bully files PCB?
It measures 257.2 × 89.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Bully files use?
136 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Bully files KiCad files?
From the zhol0777/bully-files repository on GitHub, at the commit this page was made from: the board is pcb/pcb.kicad_pcb and its schematic pcb/pcb.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Bully files design in my own project?
Its repository states no licence, so its author keeps all rights: ask zhol0777 before reusing the design.
