## Summary

Hackaday editors Elliot Williams and Tom Nardi discuss the rapid sell-out of Supercon tickets, the John Deere tractor hack at DEFCON, and a critical 'rollback' vulnerability in car key fobs that allows permanent unauthorized access. They also cover the debate over 3D CAD file formats (STEP vs. STL), a DIY magnetron sputtering rig for making daguerreotypes, and software for home PCB production using SLA printers. The episode concludes with a look at a Game Boy flashcart, Starlink ground station hacking, and a deep dive into obsolete Scenix microcontrollers by Al Williams.
