90-minute hands-on jam: plug in a Coralboard, open Control Center, and build a robot that hears, sees waves, and reacts with vibes (beeps + rainbow / red / blue).
Stack: Python on the board (greeter.py, hat.py); PowerShell + browser UI on Windows (windows/hub/). Speech uses Moonshine STT; moods use keyword rules first, optional Gemma 3 270M assist — not Gemma 4 (too large for this board).
Demo video: Watch Gemy on Coralboard (Google Photos) — public shared album: LED and buzzer reactions, laughing, yes/no answers, and greetings.
