A small DIY desk screen for watching what Claude is doing
This DIY tool uses a $25 LilyGo T-Display S3 Long screen connected to a computer over USB-C to show Claude’s current work status. It works with Cowork and Claude Code. The screen shows the active model, the tool Claude is using, elapsed time, input and counts, and the context percentage.
Tapping the screen shows 5-hour and 7-day usage bars, so limits can be checked without opening another window. It follows the Claude session that is busy, but switches to a session that is waiting for the user and shows an orange alert. If Claude Code is logged in, it can show limit numbers that are closer to the real account limits.
A custom badge or logo can be uploaded through the app, and a starter icon pack is included. The computer-side app is a standalone executable that runs from the and shows a live preview of the display. The LilyGo device must be flashed once at the start, using a provided script.
