## Summary

Hackaday editors Elliot Williams and Kristina Panos review a week of hardware hacks, including an autonomous excavator from ETH Zurich that builds load-bearing walls from boulders using algorithmic placement, and a security analysis of the 'Bluffs' Bluetooth vulnerability by researcher Yiska Klassen. They also discuss a laser-cut wedge tenon joint by Yisgar Schmitz, a nitinol-based motion machine by JGJ Matt, and a film camera made from hardboard by Chicken Crimpy. The episode concludes with commentary on an Italian lunar habitat proposal and a concept for rating airline hygiene.
