Bring Claude into the physical world with maker hardware
Claude Desktop Buddy exposes a lightweight BLE API from the Claude desktop app. It allows makers to connect Claude Cowork and Claude Code to physical microcontrollers (like the ESP32) to display states, handle permission prompts, and more.
This is a wayyy interesting bridge for Claude into physical form.
What @felixrieseberg shipped here is small, but the idea behind it is bigger: Claude Cowork and @Claude Code now expose a lightweight Bluetooth path that lets maker hardware react to sessions, recent messages, and approval prompts. The reference device is an ESP32 desk pet built on M5StickCPlus, which honestly feels like a very fitting choice — M5Stack really is one of the friendliest entry points in the hardware world🔥
It already makes interacting with Claude Code more fun to look at and touch:
But the interesting part is not just approvals. What happens when this lives on an e-ink kanban? Or when the hardware surface is something much more ambient, tactile, or playful? This is clearly the start of a much bigger hardware interaction layer for Claude!
