I bought a Waveshare ESP32-S3-Touch-AMOLED-1.8 — a thumb-sized dev board with a bright 1.8" AMOLED screen — and turned it into a desk gauge for my Claude Code usage. It sits next to my CO2 monitor and shows how much of my current and weekly limits I’ve burned. Building it was the addictive part — programming a little screen you can hold in your hand is a deep rabbit hole.
