## Summary

Hackaday editors Elliot Williams and Tom Nardi discuss the ESP32-S31 microcontroller's dual RISC-V cores and Wi-Fi 6 capabilities, alongside the potential removal of i486 support in Linux 7.1. They explore a 'threadless ball screw' mechanism for linear motion, a hack connecting Bluetooth calipers to FreeCAD for real-time parametric modeling, and the history of early 3D printing filament production. The episode concludes with a discussion on long-term data storage options and the Artemis II mission around the Moon.
