tom_doerr · x · 2026-09-29

Google open-sourced Gemma Translator, a fully offline voice translator running gemma4-e2b on a Raspberry Pi via LiteRT-LM — no internet needed after setup. Built with help from Google Antigravity, it ships a retro-terminal web UI optimized for 480x320 handheld displays, a Python API server, local TTS powered by Moonshine, and a one-shot deploy-pi.sh script that installs dependencies and launches the LLM server, API, and React frontend. The repo has already earned 1.5k stars.
