See every Claude Code session's state (running, waiting, stopped) live on a tiny ESP32-S3 touchscreen, and approve or deny tool permission requests by tapping YES/NO on the board itself, no alt-tabbing back to the terminal or editor. It's a $20 open-source hardware sidekick: a local Go server tracks sessions via Claude Code hooks, and the board polls it over Wi-Fi. Falls back to the normal terminal prompt if nobody taps in time, so it never blocks your flow.
Most backend benchmarks run on generous cloud boxes nobody deploys to. This one doesn't: a write-heavy telemetry service (GPS/battery/accel data) has to run — LB, 3 API replicas, storage — inside 2 CPUs and 500MB RAM total, on a real Raspberry Pi. Open, language-agnostic: fork it, implement the API, ship a Docker image, submit a PR. Scored on efficiency, capacity, tail latency, resilience, stability.
