The project
Personal fork of Clawd Tank by Marcio Granzotto Rodrigues (MIT license), who deserves the credit for the original firmware, simulator and daemon architecture. A pixel-art crab reacts to Claude Code activity, and this fork adds 5-hour session and weekly token usage bars, a warm sunrise in the day/night cycle, Spanish text, a watchdog fix and ghost-session cleanup.
Architecture
Claude Code hooks feed a Python daemon that sends state over BLE to the C firmware (ESP-IDF, LVGL) on the ESP32-C6, or to an SDL2 simulator when no hardware is available.
