## Summary

Hosts Elliot Williams and Tom Nardi discuss several hardware hacks, including two brothers who built custom ROVs to solve missing persons cases in Finland, and a new ergonomic input device called the ErgoRing. They also cover a controversy where fake data manipulated OctoPrint's plugin statistics, and a detailed stress test of NEMA 17 stepper motors that highlights the importance of modern drivers like the TMC2209 over the motor brand itself.
