## Summary

Dave Jones and Chris Gammell discuss a useless wrist-worn multimeter, the educational value of visual tools like Blender and quantum diamonds, and the pitfalls of camera review content. They detail Dave's struggles with a DI hybrid solar inverter's drifting internal clock and Chris's hack day project implementing a remote shell for Zephyr OS devices using Golioth. The conversation concludes with a comparison of Australian and US electrical systems and a lesson on hysteresis from a car's low-temperature warning.
