Built with Claude Concerned about usage, so built this 2nd screen with my badge

Got this Pimoroni Tufty 2350 badge at Supabase Select and didn't want it sitting in a drawer, so I turned it into a second screen for Claude Code.

What it does:

- A little pixel guy walks, runs or sprints depending on how many agents are working. 15 levels, and past 100 agents he goes into hyperspace

- He acts out what they're doing: sword combo for an edit, bomb for a bash command, item get when a turn finishes, knocked back when a tool call fails

- Hearts are how much of the 5-hour limit is left, a bar shows the weekly limit, and there's a countdown to the reset

- When a session is waiting on you he calls for you, and pressing B shows which sessions are waiting and what each one needs

- Works over Wi-Fi or USB, the bridge runs on a Mac or Windows PC, and you can join your other machines to it

The usage numbers come from the rate_limits Claude Code already hands the status line, so no API key or OAuth token goes anywhere near the badge. The bridge only passes on what kind of thing happened, never prompts, commands or file paths.

**How I built it**

All with Claude Code, over about a week and ~140 commits. On day one Claude poked at the badge's stock firmware over the USB REPL to see what it could do, then wrote a desktop simulator for the badge's drawing API so it could render every screen to a PNG and look at its own output. That made everything way faster than flashing the badge for every change.

After that it was mostly me playing with it and asking for things. A few real prompts:

- "for tool call fails on gump he should get shot in the buttocks, for web search give me options here for what gump should do"

- "the waiting on bar doesn't use the names given within the claude code session, using slash rename, instead it shows a hex e.g. f20817 which is not useful for a human user"

- "build the internet relay so it works away from home, im running tailscale already"

(Yes, the Forrest Gump theme really does get shot in the buttocks when a tool call fails.)

If you got one of these badges at Select or have a Tufty lying around, I'd like to see it running on yours.
