## Summary

Dave Young of Young Circuit Designs and Blue Stamp Engineering joins Chris Gammell to discuss the persistent challenges of the chip shortage, specifically the inability to source Raspberry Pis and instrumentation amplifiers, and the resulting need to pivot designs or pay scalpers. They analyze the consolidation of the analog semiconductor industry into a duopoly of Texas Instruments and Analog Devices, noting how this reduces supply chain resilience. The conversation also covers the technical complexities of integrating the Raspberry Pi Compute Module 4 (CM4), including the difficulty of hand-soldering 0.4mm pitch connectors and the necessity of controlled impedance for high-speed signals like MIPI DSI. Finally, they explore the implications of Amazon Sidewalk for low-cost IoT connectivity and discuss strategies for fostering engineering education and maker communities in the next generation.
