## Summary

Editors Elliot Williams and Al Williams discuss a range of hardware hacks, including a 3D printed airplane duct failure due to PLA's low glass transition temperature, and a new bridge connecting RTL-SDR to Home Assistant. They review creative clock designs like a reverse sundial and a magnetic trace-line clock, alongside a volumetric display using laser-etched glass. The episode concludes with a discussion on Dan Maloney’s decision to buy a turnkey 3D printer for a specific project, and an analysis of Maya Posch’s article arguing that LLMs lack true intelligence compared to crows.
