## Summary

Dave Jones of EEVblog and Chris Gammell of Contextual Electronics discuss the complexities of manufacturing low-run prototypes, specifically focusing on the decision to use a contract manufacturer for a box build of the EEVblog 121GW meter. They explore the nuances of assigning part numbers for assemblies and sub-assemblies, contrasting the rigid systems of large enterprises like HP with the flexible, often chaotic approaches of startups. The conversation also covers recent FCC guidance on equipment authorization, the visual interference caused by Starlink satellites, and the geopolitical implications of the US ban on Huawei.
