## Summary

Andrew Ikenberry, founder of Electrosmith and Qu-Bit, discusses the Daisy Seed platform, an embedded system for audio processing featuring an STM32H750 microcontroller and external SDRAM. He details the 'codec saga,' where supply chain disruptions forced three hardware redesigns (AKM, Cirrus Logic, TI) due to factory fires and obsolescence. Ikenberry explains how Electrosmith manages in-house SMT assembly in San Clemente to maintain quality control and iterates on manufacturing processes like reflow profiles to ensure reliability for B2B customers.
