It’s a work in progress, but, yes, you can run Claude Code through a Furby. Hardware: • Stock Furby Connect (2016). No mods, just BLE • Mac • USB mic for voice capture BLE (Bleak): • Connects via GATT characteristic to Furby's GeneralPlus chip • Two command types: antenna LED color [0x14, R, G, B] and stock actions (eyes + motors + sound) [0x13, ...] • Write-only • Auto-reconnect on drop Voice (sounddevice + Whisper): • 16kHz mono stream, RMS energy detection • Starts recording at 0.3s above threshold, stops after 1.5s silence • Clips sent to Whisper API → checked for wake phrase ("hey furby") • Wake word only → records a second clip for the actual command Claude Code (subprocess): • Spawns claude -p "<command>" with stream-json output • --dangerously-skip-permissions (no terminal to confirm) • Whitelisted tools: Read, Write, Edit, Bash, Grep, Glob Resumes session for conversation context • Parses stdout line by line → system, assistant, result events Furby reactions: • Every Claude event maps to a stock Furby action + antenna color • Thinking → giggle + purple • Writing files → hollywood lights + green • Bash → ninja dream + yellow • Success → stars + gold • Error → eyes squeezed + red • + 12 more Working on custom DLC eyes now: • 64x64 pixel art uploaded to Furby's flash over BLE at ~4KB/s • Terminal prompt, magnifying glass, loading spinner, checkmark, X mark • 6-bit palette-indexed, packed 4px per 3 bytes I have a massive Furby-induced headache. Do not recommend trying this at home.
