## Summary

Hackaday editors Elliot Williams and Christina Panos review the 2024 Home Sweet Home Automation contest winners, including Stefan Schnitzer’s SKADA system and Marcus Bindhammer’s pill-dispensing robot. They discuss several community hacks, such as P1 Security’s DIY cell phone sniffer using Qualcomm diagnostic protocols, 3D Sage’s budget bullet time rig using cheap cameras and AI interpolation, and Thomas Godden’s research on 3D printed flexure whegs. The episode concludes with a discussion on NASA’s upcoming lunar time standard and various quick hacks involving probe extenders and cyberdecks.
