He used AI to find that beep, and you won't believe what it was

A developer was haunted by an intermittent beep coming from a room full of unpacked moving boxes. Instead of digging through them, he turned to AI, asking Claude Code to build 'Beep Locator'—a software system that triangulates sound sources using multiple devices like iPads, phones, and laptops scattered around the room. The system uses acoustic ranging, inspired by a 2007 research paper called BeepBeep, to estimate device positions and listen for the mysterious sound.

The system successfully pinpointed the beep's location within about 40 centimeters. The developer finally excavated the designated pile of boxes and discovered the culprit: an ancient carbon monoxide detector screaming for a battery change. The takeaway: sometimes the most advanced solution in tech is still just finding out which old gadget needs its batteries swapped.
