## Summary

Hosts Elliot Williams and Al Williams discuss EU regulations on replaceable batteries, the winners of the Hackaday Op Amp Challenge, and the launch of the Cyberdeck contest. They review several hacks, including a Star Wars-style volumetric display by Maker's Mac using DLP projectors and 3D printing, and a cosmic ray navigation system by Japanese researchers using muons for underground positioning. The episode also covers a sonar-based car speed measurement project by G-Dub using microphones and New Radio, and a vertical-landing model rocket by TTS Aerospace featuring custom flight controllers and PID loops.
