## Summary

Hosts Elliot Williams and Al Williams review Hackaday news, highlighting Michael Rechton's 3D-printed quadcopter that exploded due to a battery drill, and Les Wright's use of anise extract (anethole) to create a fast optical laser switch. They also discuss DIY semiconductor fabrication using a home-built tube furnace, 3D-printed thermoforming molds, and an Arduino-powered mouse trap. The episode concludes with a semi-annual debate on Vim versus Emacs editors and a look at logic analyzers for debugging serial protocols.
