Partial The software backend and display animations can be vibe-coded, but the project requires physical microcontroller hardware assembly, audio I/O streaming, and embedded C++/FreeRTOS programming on the ESP32-S3.
What it would actually take: Building FUMI requires an ESP32-S3 firmware layer handling I2S audio input/output, display drivers for small LCD/OLED screens, and power/battery management. The cloud backend acts as an orchestrator using WebSockets or MQTT to stream audio to speech-to-text, LLM, and text-to-speech pipelines. Embedded systems engineering and hardware prototyping expertise are essential alongside the cloud AI integration.
