He communicates in musical chords. This project implements a Dual-Device \"Voice Box & Brain\" Architecture to bring Rocky to life on a Raspberry Pi Zero 2W with near-instant responsiveness. [!IMPORTANT] Looking to build your own Rocky? Check out the Step-by-Step Installation Guide (BUILD YOUR OWN ROCKY.md) ! It covers setting up a fresh Raspberry Pi Zero 2W, installing the PiSugar Whisplay HAT and audio drivers, setting up uv , configuring Google Gemini vs Local LM Studio, and running offline Piper TTS voice models. [!NOTE] Update (May 17, 2026): Piper TTS Integration! Rocky can now speak with a human voice in parallel with his Eridanian musical chords! This upgrade is completely opt-in, fully configurable via your .env file, and allows you to load custom .onnx voice models. Check out the new demo video below! Demo Videos: Full Build Video: Piper TTS Feature Demo: --- ✨ Core Features - Lore-Accurate Eridanian Synthesis : Generates polyphonic chords in real-time. Specific words map to emotional chords (e.g., \"amaze\" is a bright E Major), while unknown words are mathematically hashed to permanent, unique 3-frequency signatures. - Dual-Brain Architecture : - Voice Box (Pi Zero 2W) : Handles recording, hardware LEDs, LCD display, and Eridanian voice synthesis. - Brain (Mac Hub) : Uses Apple Silicon-optimized mlx-whisper (specifically the Whisper-Tiny model) for n","default_branch":null,"files":null,"tree":[],"storefront":"/r/lahirumaramba","claimed":false,"request_supported":{"post":"https://gitbuyer.com/r/lahirumaramba/rocky/request-supported","requests":0},"note":"indexed from public GitHub; nothing is for sale on this page.
