README

Temporal

A 36-42 key split ergonomic keyboard with wireless support, a breakoff pinky column, and optional encoders in the thumb cluster.

Design

Layout

36-42 keys depending on configuration:
- 42/41/40 keys (0/1/2 encoders) with full pinky column
- 38/37/36 keys (0/1/2 encoders) with breakoff pinky column
Column stagger and splay on pinky and ring columns

Hardware

Kailh Choc v1 or v2 low-profile switches, with optional hotswap sockets
nice!nano or other Pro Micro compatible microcontrollers
Optional nice!view display
Optional EC11/EC12 rotary encoders in thumb cluster (up to 2)
Wireless with battery support
Reversible PCB
3D-printable cases, with an optional kickstand for tenting

Tools

Ergogen generates the layout, PCB, plates, and cases from ergogen/config.yaml
KiCad v10 holds the hand-routed traces; its pcbnew API and kicad-cli drive the scripted post-processing and the exports

Firmware

Temporal runs ZMK. The shield definition and default keymap live in temporal-zmk; curbol/zmk-config is a working config that uses it.

docs/build-guide.md covers assembly and ordering. docs/bom.md lists every component a full build needs.

Keycaps

Any Choc-compatible keycap fits. KLP Lame Keycaps are 3D-printable and sculpted; docs/bom.md lists the print quantities for a full build.

Development

Prerequisites

Node.js and npm
A package manager make deps can drive: Homebrew on macOS, or pacman and yay on Arch Linux

Setup

Install dependencies (OpenSCAD, KiCad, zip/unzip, Maple Mono NF font, and KiCad plugins):

make deps

Generate PCBs and cases:

make gen

This will:

Run Ergogen to generate PCB and case files
Derive temporal.json, the ZMK Studio physical layout, from the same points
Post-process PCBs (edge cuts, silkscreen widths, ground planes, text keepouts, via stitching, zone fills, embedded fonts)
Configure KiCad project files with defaults from scripts/kicad_config.yaml
Derive the top_plate_*_stealth variants from the generated top plates
Render assets/preview.svg and a pcb.png per board
Export gerbers for manufacturing
Generate the JLCPCB BOM and CPL files in jlcpcb/
Generate STL case files

Note: The main pcbs/temporal/ PCB requires manual steps in KiCad after generation. See pcbs/temporal/README.md for details.

Verifying

make check

Confirms the sources parse and lint, ergogen/config.yaml builds, every committed board passes DRC and carries its own silkscreen font, and the pours in pcbs/ still match the custom DRC rules and the zone settings. It then regenerates each committed derived artifact and diffs it against what is checked in: temporal.json, jlcpcb/, the .kicad_pro and .kicad_dru files, the top_plate_*_stealth boards, and the gerber zips. This is what CI runs on every push.
