From Simon Willison, the guy who brings us pelicans riding bicycles – beep locator!

Our house has a box room, full of boxes that we still haven’t unpacked from our last move. A couple of weeks ago something in that room started intermittently beeping. The beeps were far enough apart that standing in the room and trying to determine the source of the noise was frustrating, and I really didn’t want to dig through every one of those boxes. So I had Claude Code build Beep Locator, a software system for triangulating the source of a mysterious beep using multiple devices scattered around the room.

Turned out it was an old carbon monoxide detector with a dying battery.

As Robin Sloan says, ask for what you want.
