Claudigotchi: Physical Tamagotchi Device That Feeds on Claude Code Activity
What Claudigotchi Does
Claudigotchi is a physical desktop device that monitors your Claude Code activity and responds with visual and audio feedback. It's built as a pixel-art character in a 3D-printed case, running on an ESP32 microcontroller with an LCD screen.
How It Works
The system connects Claude Code to the physical device through this pipeline:
- Claude Code hooks → shell script → named pipe → Python daemon → USB serial → ESP32
A Claude Code plugin hooks into session events and sends state updates over serial connection. Every tool call, prompt, and notification from Claude Code feeds the creature and lowers its hunger level.
Hunger System Details
The hunger system operates on a scale from 0 (full) to 100 (starving), with five distinct visual states. When Claude Code is left idle, the creature becomes restless, looks around, and eventually emits R2-D2-style buzzer sounds through its speaker to prompt you back to work.
Technical Implementation
The entire project is open source, including:
- Firmware for the ESP32
- Claude Code plugin
- 3D-printable STL files for the case
The source code and files are available on GitHub at github.com/jsprpalm/claudigotchi.
