## Summary

Hackaday editors Mike Szczys and Elliot Williams discuss a week of hardware hacks, including a 3D-printed wire connector design by Harvey Mudrunchka and a tuning fork clock by Chris Slyka. They analyze the Texas power grid failures caused by freezing natural gas infrastructure and wind turbines, and examine Tesla's recall of pre-2018 Model S vehicles due to eMMC flash memory wear-out from excessive logging. The episode also covers reverse-engineering an air quality meter with Ghidra, spinach-based photo prints, and the use of automotive bedliner to finish 3D prints.
