## Summary

Dave Jones and Chris Gammell discuss the technical challenges of EV charging infrastructure, including Type 1 vs Type 2 connectors and DC fast charging, while analyzing Tesla's Battery Day announcements on cell manufacturing and material science. They explore embedded firmware development using the Zephyr RTOS and nRF52840 microcontrollers, highlighting the pain of setting up cross-platform toolchains. The conversation also covers historical wiring issues like knob-and-tube and rotted cables, alongside recent open-source hardware announcements from Kosagi and QuickSilicon.
