OpenClaw in Your Hand: Building a Physical AI Terminal
summary
Vault handheld terminal is a text-first dual-display device built on a single ESP32-S3 and one battery cell, pairing a fast emissive OLED with a slow bistable e-paper and switching between four modes: shell, assist, control, and an LLM-native RPG. A dependency-free Python backend serves gpt-oss:120b via TensorRT-LLM locally, drives OpenClaw agents, and keeps inference off the MCU. 130 commits over three months, major power and I2C fixes, and the prototype works end-to-end.
