## Summary

Hackaday Managing Editor Elliot Williams and Staff Writer Dan Maloney review a week of hardware hacks, including Tom Nardi's manual BGA breakout, Terrence Eden's floppy disk music player, and Nicolas Geritis's wall-climbing robot. They also discuss Eric Urban's RTL-SDR antenna testing, Fabian Cousteau's Proteus underwater lab, and teardowns of a digital pregnancy test and a GPS jammer. The episode highlights creative engineering solutions, from using urine as a power switch to maximizing utility per servo in robotics.
