The badge disciplines its internal RTC with GPS time data, achieving millisecond-level accuracy despite lacking a PPS pin. Notably, the entire 2141-line MicroPython app was vibe-coded using Claude without manually editing a single line of code. Geerling also used Claude to generate an interactive data visualization of GPS satellite fix quality logged throughout the event venue. He reflects on the irony of using AI to build a project while attending an event that felt like a refreshing escape from AI-dominated online culture. ## Full article daily.dev links to this article rather than hosting it.
