## Summary

Dave Jones and Chris Gammell discuss the Keysight HD3 oscilloscope, highlighting its 14-bit ADC and Megazune 5 ASIC, and debate the practical value of such high resolution. They then explore MeshTastic, a community-driven mesh networking protocol built on LoRa, using ESP32-based hardware like the Heltec V3 to enable encrypted, off-grid communication. Finally, they touch on the new Embedded World conference in Austin and the complexities of residential smart meters and energy management.
