Hardware × software. I design PCBs with AI agents and scripts, build IoT / embedded systems (ESP32, nRF, Raspberry Pi), and fix the open-source EDA tools I run into along the way.
| Project | What it is |
|---|---|
| kicad-scripted-pcb | Three KiCad 10 boards written entirely as Python: schematic → ERC → netlist check → datasheet design review → placement → freerouting → DRC → Gerber/BOM/CPL. Byte-for-byte reproducible builds, ngspice simulations, a 2-D field solver for trace impedance. |
| easyeda-pro-extension-notes | Field notes on EasyEDA Pro's extension host: why side-loaded extensions never activate after a restart, and how to get evidence when they don't. 中英雙語。 |
| usbc-5v-to-3v3-ldo | A USB-C 5 V → 3.3 V board designed end-to-end by an AI agent. |
| selfhosted-llm-toolkit | Connect a self-hosted OpenAI-compatible LLM (vLLM / LiteLLM / Ollama) to coding agents, a web UI and a terminal chat. |
| iot-energy-cloud | Multi-tenant IoT energy-management platform (EMQX + InfluxDB + FastAPI). |
- freerouting: CLI
-lflag read as both language and log path (#963); LLM scaffolding leaking into locale files (#964) - FluidNC: swapped MISO/MOSI arguments for SPI Ethernet PHYs (#1835)
- easyeda-agent: 14 merged PRs, including the schematic-frame y-sign bug (#238), a native Windows installer (#229) and fixes for CI on dev versions (#232)
- Bug reports to Espressif (esp-eth-drivers#178, W5500 reset timing) and EasyEDA (easyeda-api-skill#18, extension activation)

Every board here passes ERC/DRC, but none has been manufactured yet. Checks are scripted; the final review is human.
