## Summary

Hackaday editors Elliot Williams and Tom Nardi discuss recent community projects, including atomic decay clocks by Alan Wilson and Mihi Kuiciches, and new 3D printing filaments like polypropylene and foaming TPU. They review a guide to schematic best practices by Graham Sutherland and a project repurposing old Android smartphones as low-power Linux servers using postmarket OS. The episode concludes with a look at Lorde's transparent CD playback issues, a soluble circuit board prototype from the University of Maryland, and open-source firmware QMK for custom input devices.
