## Summary

Hosts Elliot Williams and Dan Maloney discuss a variety of hardware hacks, including Sharam Moktari's analysis of wireless charging inefficiencies, which show 60% energy loss compared to wired charging. They cover the reverse engineering of the QuanShang UVK5 ham radio by mental detector and colleagues, detailing the destructive PCB layering process. The episode also highlights Priscilla's discovery of a Windows networking bug caused by a smart TV, Grant's demonstration of RF burns from AM radio antennas, and Joran's pitch-detection mouse using an RP2040. Finally, they review Andrews Nielsen's universal EPROM programmer and discuss using barnacles to track MH370 debris.
