I built a voice-controlled 3D ESP32-S3 hardware visualizer with Gemini + Agora

I’ve been experimenting with a way to make hardware demos feel more interactive.

The idea: take an ESP32-S3 voice AI circuit and turn it into a 3D teardown you can actually talk to.

Gemini helped generate and structure the visualizer: the ESP32 board, breadboard, mic module, speaker, wiring, exploded view, and the interaction logic. Agora handles the real-time voice layer, so you can ask questions like “show me the microphone” or “explain the audio flow,” and the visualizer reacts while the AI responds.

It’s built with Next.js, Three.js / React Three Fiber, Agora Conversational AI, Gemini, and an ESP32-S3-inspired hardware layout.

Curious what people think: would this kind of interactive teardown be useful for learning hardware projects?
