## Summary

Hackaday editors Mike Szczys and Elliot Williams review the week's top hacks, including Mike's digital hourglass built with an ESP32 and cellular automata, and Darren Schwanky's 3D-printed planetary gear transmission. They discuss Michael Osman's analysis of an analog failure in the Great Scott Gadgets HackRF1 production run and Rick McDonald's ultra-accurate GPS clock using an FPGA to eliminate microcontroller jitter. The episode concludes with a look at a neighborhood keyfob jamming incident in Ohio and an investigation into the Supermicro supply chain controversy.
