Open-source HUD displays live Claude usage on $38 Thermalright Trofeo Vision LCD via macOS
A developer-built tool streams real-time Claude API usage metrics to a low-cost USB-C LCD panel using local logs and Anthropic’s endpoint.
This project demonstrates how to repurpose inexpensive hardware for custom AI monitoring without cloud dependencies. It also highlights the trade-offs of relying on reverse-engineered protocols and local credential access for unattended operation.

The HUD shows session limits, token burn rates, and hypothetical API costs on a 1280×480 USB-C LCD panel.
Requires macOS, Python 3.12+, and local access to Claude Code’s Keychain credentials to function.
Uses a reverse-engineered HID protocol to bypass macOS restrictions on libusb for the display
