Show HN: Live Claude Usage HUD for a $38 Thermalright Trofeo Vision LCD

A developer released claude-trofeo-hud, an open-source macOS tool that displays live Claude usage on a $38 Thermalright Trofeo Vision 6.86-inch LCD (1280×480, USB-C) via a reverse-engineered HID protocol. The HUD shows Pro/Max session and weekly limit bars with reset countdowns from Anthropic's usage endpoint, today's tokens and hypothetical API cost via ccusage, live session details, a clock, and an hourly token sparkline. It requires Python 3.12+, uv, Node, hidapi, and Claude Code, and can be installed as a launchd agent for unattended startup.

A desk HUD that shows live Claude usage on a Thermalright Trofeo Vision 6.86" LCD 1280×480, USB-C, ~$38 , driven from macOS. Inspired by the r/ClaudeAI "$38 Claude LCD Table Display" post. What it shows: Pro/Max session + weekly limit bars with reset countdowns from Anthropic's usage endpoint , today's tokens and hypothetical API cost via ccusage https://github.com/ryoppippi/ccusage , the live session project, model, burn rate , a clock, and an hourly token sparkline. - macOS, Python 3.12+, uv https://docs.astral.sh/uv/ , Node for npx ccusage brew install hidapi C library behind the hidapi Python package - Claude Code installed and logged in the HUD reads its local logs and its OAuth token from the Keychain — read-only, nothing leaves your machine except the usage query to api.anthropic.com uv sync uv run python -m claude trofeo hud preview render mock layout to out/preview.png uv run python -m claude trofeo hud run live HUD on the LCD Ctrl-C stops uv run python -m claude trofeo hud install-agent start at login via launchd On the first run , macOS asks for Keychain access to "Claude Code-credentials" — choose Always Allow so the daemon can run unattended. uninstall-agent stops and removes the launchd agent. Config lives in config.toml /christensen143/claude-trofeo-hud/blob/main/config.toml fps, JPEG quality, night dim/off hours . Logs go to ~/Library/Logs/claude-trofeo-hud/ . The panel is not a monitor — it's a USB HID device VID:PID 0416:5302 that accepts JPEG frames over a reverse-engineered protocol. We use the device classes from thermalright-trcc-linux https://github.com/Lexonight1/thermalright-trcc-linux with its HidApiTransport IOHIDManager , bypassing its CLI — trcc's default transport routes through libusb, which macOS blocks for HID devices. The firmware blanks when idle, so the HUD streams continuously default 2 fps . See PLANNING.md /christensen143/claude-trofeo-hud/blob/main/PLANNING.md for the full protocol notes. "Access denied insufficient permissions " — something is opening the device via libusb instead of hidapi; make sure you're running our CLI, not trcc directly. Panel shows boot logo / blanks — no frames arriving; check ~/Library/Logs/claude-trofeo-hud/hud.log . Unplug/replug is handled automatically with backoff. Empty cost/tokens — npx ccusage must work in a terminal first; the launchd agent bakes the node path into its plist at install time, so re-run install-agent after Node upgrades. Limits stale — Keychain access not granted, or you're logged out of Claude Code.
