## Summary

Hosts Elliot Williams and Dan Maloney review a diverse range of hardware hacks, including a Raspberry Pi Pico-based bat detector by Omeni, a nostalgic cable TV simulator by Irish Crack Party, and a spring-loaded trebuchet by Andy's Machines. They also discuss a $3 board used to brute-force Android PINs, a DIY green laser for PCB etching by MakerLab Munich, and a Hallbach array experiment by Wannabe Madsi. The episode concludes with discussions on the history of duct tape and the pedagogical value of learning assembly language.
