## Summary

Hosts Elliot Williams and Kristina Panos discuss Bambu Labs' controversial authentication scheme that locks 3D printers to their cloud, forcing users to choose between cloud features and local control. They highlight a reverse-engineering hack of a Yamaha PSR-E433 keyboard that allows running a shell and video via MIDI, and explore the use of bone-simulating filament for surgical planning. The episode also covers a logic-gate-based Commodore 64 clone, an exploding wire experiment, and a caustic lens clock.
