WORK LOAFER EDITION · MECHANICS REV B · ELECTRONICS REV A2

A from-scratch, manufacturable parody of the Codex Micro: Fusion 360 mechanics,
four quoted CNC parts, a wired six-layer PCB, turnkey assembly instructions, and working USB HID firmware.

THIS IS NOT A DISCLAIMER.
THIS IS THE WHOLE POINT.

ABSOLUTELY EVERYTHING HERE IS 100% VIBE-CODED.

FROM THE FIRST PROMPT TO FUSION 360, KICAD, GERBERS, FIRMWARE,
AND A REAL UPLOAD INTO JLCPCB + JLCCNC.

THIS IS THE PRODUCT STORY: ONE CONTINUOUS VIBE
FROM A PUBLIC PRODUCT IMAGE
TO A REAL, QUOTED, FACTORY-READY HARDWARE STACK.

THE DELIGHTFUL PART IS THAT THE VIBE DID NOT STOP WHEN THE WORK BECAME PHYSICAL.
It crossed industrial design, parametric CAD, CNC drawings, multilayer electronics, component sourcing, USB firmware, factory testing, pricing, and vendor handoff. Every layer is editable, inspectable, and ready to continue.

One vibe, all the way to the factory

Most vibe-coded projects end at a screenshot. This one kept going until the pixels became toleranced solids, the solids became quoted CNC parts, the control layout became a routed six-layer PCB, the PCB became Gerbers/BOM/CPL, the firmware became checksummed factory binaries, and the whole stack became live JLC manufacturing jobs.

That is the fun of this repository: the same conversational build loop moves through every engineering discipline without hiding the seams. “The aluminum base is slightly tilted” became a 5° Fusion body. “Not a foot, a ring” became a purchased JIS G‑65 O-ring, a concentric retention groove, refreshed STEP/DXF/PDF exports, a successful JLCCNC import, a $68.31 live base quote, and a cleaned cart. “I do not want to solder switches” became a both-side PCBA configuration, consigned-parts manifest, 74-position placement file, manual assembly contract, flashing procedure, and functional acceptance test.

PROMPT → RESEARCH → DIMENSIONS → FUSION 360 → STEP/DXF → JLCCNC
                     ↓
              ELECTRICAL PLAN → KICAD → GERBER/BOM/CPL → JLCPCB
                     ↓
              FIRMWARE → FACTORY TEST → TURNKEY HANDOFF → A FEW FINAL SCREWS

The result is not “AI made a picture of a keyboard.” The result is a versioned hardware project in which a vibe-driven decision can be traced from sentence to parameter, from parameter to geometry or net, and from production file to a factory price. That end-to-end continuity is the project.

The whole device, not just a render

Yes: the factory does the hand work

ZERO SOLDERING AT HOME. The production route asks JLC to place both-side SMD, manually install the twelve switches and encoder, fit the joystick/FFC, flash the STM32, exercise all 20 USB HID events, inspect all 24 RGB emitters, and install the caps on the primary unit. The customer-facing operation is enclosure closure after first-article approval.

The automatic JLC matcher uses the catalog-only BOM and CPL. The complete manual/secondary-operation contract is in the turnkey SOP, expanded BOM, 74-position CPL, and consigned-parts manifest.

Live manufacturing snapshot

Quotes were captured in an authenticated JLC session on July 17, 2026. Prices are dynamic and exclude possible tax, duty, and engineering-review additions.

The $193.01 PCB/PCBA figure is a captured base, not a promise of a finished-device total. Programming, functional test, secondary manual operations, and consigned-part handling remain quote-after-review. The saved cart proves that the geometry and six-layer board can enter the vendor workflow; JLC engineering approval is still the gate before payment.

What is actually in the repository

Electrical architecture

• STM32F072CBT6, 128 KB flash, crystal-less HSI48 + CRS USB.
• USB-C device input, dual 5.1 kΩ CC resistors, USBLC6 ESD protection.
• Six layers: F.Cu, GND plane, two signal layers, +5V plane, B.Cu.
• Twelve low-profile matrix switches plus clickable encoder.
• Capacitive touch and two-channel analog planar joystick.
• 24 × SK6812MINI-E: twelve per-key, nine underglow, three status.
• Build-verified TinyUSB firmware with BIN/HEX/ELF artifacts and a browser factory test.
• Housing interface intentionally remains compatible with a future replacement ESP32-S3/BLE board.

Mechanical datum set

The coordinate origin is the device center. +Y points toward the rear edge; +Z points upward.

Confidence language is deliberate:

• CONFIRMED — explicitly published by OpenAI, Work Louder, or a component manufacturer.
• MEASURED — scaled from a public, near-orthographic product render.
• INFERRED — a manufacturable placeholder that still requires physical first-article inspection.
• ENGINEERED — a derived interface sized from known parts, tolerances, and adjacent clearances.
• PURCHASED / VERIFIED — an exact orderable catalog part with checked dimensions and a live cart entry.

CNC material directions

The current quoted Rev B build uses polished black POM for the upper housing and joystick cap, black-anodized 6061-T6 for the 5° base, clear cast PMMA for the captured light pipe, and a purchased black NBR G‑65 ring. A wood upper remains a future material experiment, but it is not the current cart configuration.

All four STEP files passed JLC's automated CNC import. The current bottom was explicitly corrected from an early flat disc to the observed 5° wedge, then revised again with the G‑65 retention groove before the $68.31 configuration was saved. Obsolete flat/no-groove parts and individual rubber feet were removed from the cart.

Reproduce it

1. Open or create the Fusion document named Codex, then run fusion/build_codex_micro_mechanical.py.
2. Export/audit CNC bodies with the scripts in fusion/ and compare them with the controlled drawing pack.
3. Open the board in KiCad 10 and verify the committed DRC report before regenerating fabrication data.
4. Build the STM32 target from firmware/stm32/ or use the checksummed release image.
5. Upload the Gerber ZIP, JLC BOM/CPL, CNC STEP files, drawing pack, and turnkey factory ZIP.
6. Do not authorize production until JLC DFM, polarity/rotation, manual-operation scope, and first-article dimensions are reviewed.

Prototype status and provenance

This is an independent private prototype, reconstructed from official public product renders and published platform/component documentation. It is not an official OpenAI or Work Louder CAD/electronics release, is not affiliated with or endorsed by either company, and contains no leaked manufacturing data.

The digital production gate is clean: Gerbers, drill files, BOM/CPL, IPC netlist, three-sheet principle schematic, firmware, STEP/DXF, drawings, and vendor quote evidence are present. The physical gate is still open: no fabricated Rev A2 board has completed electrical bring-up, EMC evaluation, or dimensional fit-check. Use a current-limited supply, verify the 3.3 V rail and SWD first, and treat the first order as an engineering prototype.

Primary research links and detailed source notes live in the manufacturing dossier and firmware-and-compliance-notes.md.
