## Summary

Hosts Dave Jones and Chris Gammell discuss the challenges of PCB layout, specifically the transition between Imperial and metric units in CAD software, and the iterative nature of schematic design involving component substitution. They analyze the Raspberry Pi's massive commercial success through Farnell and the ethical implications of established companies like Crystal Fonts using Kickstarter for publicity rather than funding. The conversation also covers the history of PCB design tools, patent trolling by Intellectual Ventures, and the hosts' personal projects including a new mill and homebrew RF circuits.
