## Summary

Hosts Chris Gammell and Dave Jones discuss Gammell's recent experience hiring paid tutors to accelerate his learning of GCC and debugging for a new hardware project, contrasting this with informal mentorship. They analyze the economic viability of ultra-low-cost PCB manufacturers like JLCPCB and the real-world impact of US-China tariffs on component sourcing, citing a personal $500 tariff bill. The episode concludes with a discussion on Australian legislation protecting the title 'Professional Engineer' and the history of Wi-Fi patents.
