## Summary

Hosts Elliot Williams and Tom Nardi discuss David Cuartielles, co-founder of Arduino, who will keynote Hackaday Europe on compostable electronics. They analyze a research paper on hijacking Apple AirTag infrastructure by exploiting weak Bluetooth Low Energy address randomization, and detail how a flat-pack toaster by Casey Ho prioritizes repairability and user assembly over aesthetics. The episode also covers a GPS week-number rollover workaround using an RP2040, a fiber-optic display mapped via computer vision, and a review of hardware presence at FOSDEM 2025.
