Xiaozhi Smart Electronics Workbench Ecosystem
• Lead Architect & Developer
- Engineered an edge-to-cloud distributed lab environment connecting ESP32-S3/P4 voice satellites to a central Ubuntu hub and 7-inch capacitive touchscreen kiosk.
- Designed and published a JSON-RPC 2.0 Model Context Protocol (MCP) Server with 9 verified agentic tools, allowing autonomous AI agents (Claude Desktop, Cursor, Antigravity) to query multimeters, toggle bench relays, and manage component drawer stock.
- Implemented a dual-screen telemetry dispatch pipeline driving a high-contrast 2.8" SPI display at the soldering bench and live WebSocket browser mirrors.
Autonomous Circuit Builder & SVG Simulator
• Core Creator
- Created a dependency-free, high-performance browser-based schematic playground capable of drag-and-drop component placement (ESP32, Raspberry Pi, LD2410 radar, MQ-2 gas sensors).
- Integrated generative AI routing to parse conversational circuit requests into verified netlists and automatically broadcast pinout wiring instructions to benchtop displays.
24GHz mmWave Bench Automation & Safety Control
• Hardware & Firmware Engineer
- Constructed an automated lab safety system utilizing LD2410 24GHz microwave radar sensors to detect bench presence and automatically control dual optocoupled relays for soldering iron and glue gun power lines.
- Connected live environmental telemetry (DHT22 temperature, humidity, air quality) to Adafruit IO cloud feeds with sub-3-second polling.
Global Push-to-Talk Linux Dictation & Command Daemon
• Systems Engineer
- Developed an asynchronous Linux hardware service reading tactile switches on GPIO 2 & 22 with software debouncing.
- Pioneered dual-mode voice gesture inference: momentary hold routes I2S INMP441 audio to Groq Whisper for typing dictation; quick tap-and-hold automatically launches Konsole terminal and executes spoken CLI instructions.
04. Community & Open Source Leadership
Leading an open collective of makers and embedded engineers dedicated to open-sourcing hardware blueprints, PCB schematics, and tutorials bridging artificial intelligence with hands-on solder and silicon.
