## Summary

Editors Elliot Williams and Dan Maloney discuss a wide range of hardware hacks, including Stephen McCulloch's technique for printing 90-degree overhangs in 3D by using circular paths, and a teardown of a Chinese clone of Ben Katz's open-source Mini Cheetah robot. They also cover Sam Mulvey's low-power FM radio station built from dumpster-dived gear, the structural collapse of a massive acrylic aquarium in Berlin, and Jim Metcalf's stereo macro photography rig. The episode concludes with news on a Soyuz capsule coolant leak leaving ISS crew stranded and a deep dive into USB-C connector mechanics by Aria Voranova.
