Latest update (11-09 18:57): Simon Willison builds a beep locator with Claude Code and networked devices

Overview: Simon Willison says he had Claude Code build Beep Locator, software that triangulates a beep's source using several devices placed around a room. The devices listen through browser microphones connected over WebSockets. Willison says the system located the beep to within about 40 cm, which led him to an old carbon monoxide detector that needed new batteries. He says Claude Code built the project from a 2007 BeepBeep acoustic ranging paper that it found.
