## Summary

Dave Jones and Chris Camel discuss the quirks of online circuit simulators like Falstad and LTSpice, specifically the confusing use of 'beta' for MOSFETs. They analyze Derek Muller's (Veritasium) follow-up video on energy flow in transmission lines, debating Poynting's theorem versus the lumped element model. The conversation shifts to embedded systems debugging with SEGGER tools, the ongoing microcontroller supply chain crisis, and the challenges of adopting open-source solar microinverters.
