## Summary

Hackaday editors Mike Szczys and Elliot Williams discuss the upcoming Hackaday Supercon badge, which features an FPGA and custom audio synthesis, and review several community hacks including the open-source Ploopy trackball, a Castlevania-playing LED cube, and a laser-induced vulnerability in MEMS microphones. They also cover a 3D printing technique for stronger parts by 'smooshing' extrusion, a Bluetooth-enabled pocket welder, and a facial projection mask costume. The episode concludes with a deep dive into the history of UNIX and Linux, and the engineering challenges of stopping deep-sea oil spills.
