## Summary

Hackaday editors Mike Szczys and Elliot Williams review a week of hardware hacks, including a Purler printer by Joshua Vasquez, a modular robot arm by John Lauer, and a Coandă effect hovercraft by Tom Stanton. They also discuss Alessandro Ranellucci’s work as Italy’s open source lead and analyze why worn-out eMMC chips in Teslas cause 'limp home mode' failures. The episode covers diverse projects ranging from 3D printing software history to DIY manufacturing techniques like cutting chain sprockets from construction brackets.
