## Summary

Hackaday editors Elliot Williams and Mike Szczys review hardware hacks including 3D-printed injection molds, vintage telephone tape loops, and Blender-based optical design. They discuss the Nintendo Switch Joy-Con drift issue, the Smoothie Board's microcontroller shortage, and the history of the Mercury 13 women astronauts. The episode also covers quick hacks like an 8051 keylogger and a Casio calculator internet stack.
