Projects
Open Source Hardware
A growing catalog of fully-automated PCB designs. Each project ships with a structured spec, BOM, schematics, mechanical renders, and assembly instructions — generated from a single TOML file via the same pipeline that builds the boards.
DS-01 designed
Door Security Controller
ESP32-S3 door controller — 12V latch driver and reed-switch input on a 2-layer carrier for the ESP32-S3-DevKitC.

How this works
01 — Author
One TOML per project
Each project is a single TOML file under
site/src/projects/. Drop a sibling
-bom.csv and the BOM tab populates automatically.
02 — Render
Same template, every project
INFO / BOM / WIRING / MECH / INSTRUCTIONS sections render automatically from the data.
Empty sections show "Not yet populated" and link to the relevant roadmap item.
03 — Eventually
Prompt → TOML → real PCB
The same TOML format becomes the output of an LLM pipeline (see roadmap).
From there it flows into the existing designgraph + router for actual fabrication.
