## Summary

Hosts Elliot Williams and Dan Maloney review recent hacks, including Zach Frieden's 4-axis circuit graver that uses a lathe tool to engrave PCBs with high precision, and Eric Yufang Wu's wiring-free quadruped robot that mounts motors directly to a PCB spine. They also discuss a National Academies report on the Arec Observatory collapse, attributing the failure to electroplasticity in zinc sockets caused by RF energy, and highlight Max Scheffler's portable solder paste station that uses vacuum pressure to prevent smearing. The episode covers reusing old Android phones via FTDI GPIO, hardware-in-the-loop testing, and long-form articles on installing Gentoo Linux and the mechanics of vintage video tubes.
