Claude Usage Stick

Claude Usage Stick

Your Claude Code rate limits, glanceable on a tiny ESP32 stick.

⚡ Flash your ESP32 — right from your browser

*No toolchain, no drivers, no clone — just Chrome, Edge or Firefox and a USB-C cable.*

*5-hour & 7-day usage windows · reset countdowns · model health mascots · PIN-encrypted token · web control panel · screen carousel with 7-day chart, Anthropic news & clock (✨ Dust, v3)*

A standalone desk gadget that polls the Anthropic API and shows your Claude Code rate-limit usage in real time — no computer, no app, no cloud. Flash it, connect it to WiFi from your phone, and it just sits there telling you how much runway you have left.

What it does

On every board

- Live usage bars — the 5-hour and 7-day rate-limit windows, read straight from the anthropic-ratelimit-unified-* headers, refreshed every 30 s – 5 min
- Reset countdowns — exactly how long until each window frees up
- Model health mascots — Haiku / Sonnet / Opus / Fable from status.claude.com as blinking Clawds (Mango v2+)
- PIN-encrypted token — AES-256-GCM on the device's own flash; the PIN is never stored, and 10 wrong tries wipes it
- Captive-portal setup — no hardcoded credentials, no serial console; configure it from your phone

✨ New in Dust (v3 — T-Display S3 and M5StickC Plus)

- Web control panel — the stick serves its own settings page at http://claude-usage-stick.local: every setting, WiFi changes and factory reset from any browser on your LAN. Logging in with the PIN also unlocks the screen
- Token rotation without a reset — paste a fresh claude setup-token, confirmed with your PIN and verified live against the API; the stored token is write-only
- Screen modes — static, carousel (dwell 5–30 s) or desk clock; Button A steps through every screen
- 7-day usage chart — one…
