AI usage, on the desk.

Octagon Pulse showing current-session and weekly usage bars for one provider

A small ESP32 dashboard that keeps an eye on Claude Code and Codex usage. It pairs with the laptop over Bluetooth: a Python daemon polls usage every minute and pushes it to a 2.16" AMOLED touch screen. With one provider it shows full-size session and weekly cards; with two it switches to side-by-side columns. The side buttons double as a Bluetooth keyboard for Claude Code's voice and mode shortcuts.
