What this episode covers

Dave Jones, founder of Parks Audio, explains how his Puffin phono preamp uses a Cortex-M4 microcontroller to apply digital signal processing to analog vinyl records, addressing the specific needs of audiophiles. He details the engineering challenges of managing limited 64KB memory, using single-precision floating-point math, and implementing a custom pop-and-click suppression algorithm called 'Magic'. Jones also discusses his business strategy of selling directly to consumers via Amazon FBA while maintaining a single-product focus to manage his one-person factory operations.

    471: Bicycle Built For Two

    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.
