Building CircuitSense: How I Built a Dual-Engine AI Lab Partner That Sees Your Hardware

This article was created for the purposes of entering the Gemini Live Agent Challenge hackathon. #GeminiLiveAgentChallenge $44 Billion in Electronic Waste. Zero AI Tools to Fix It. Every year, 44 billion dollars worth of electronics gets thrown away — not because it's broken beyond repair, but because nobody knows what's wrong with it. A technician stares at a PCB. Is that capacitor bulging? Are those solder joints cold? Which IC is this? Where's the datasheet? The tools haven't changed in decades: a multimeter, a magnifying glass, and Google. Meanwhile, AI can drive cars and generate movies — but it can't look at a circuit board and tell you what's wrong? Until now. Meet CircuitSense CircuitSense is an AI lab partner that sees your hardware through your camera and talks to you about it in real-time . No typing. No uploading photos. No waiting. Point. Ask. Fix. 🔍 SCAN — Identifies every component, checks physical condition, detects protocols 🔧 DIAGNOSE — Hunts for faults: burnt traces,
