## Summary

Eli Hughes, a full-stack embedded engineer and educator, discusses his 'Super Monkey' guitar active pickguard project, which uses an NXP i.MX RT685 processor for DSP and a Nordic nRF7002 Wi-Fi chip for cloud data upload. He explains the technical rationale for choosing Zephyr OS for its standardized, reusable software stack and emphasizes the importance of a 'beginner's mindset' and rigorous hardware bring-up procedures. The episode also covers news items including the Waveshare BG95-M3 Zero cellular SBC, the Raspberry Pi M.2 HAT+, and Breadboard OS for the Pi Pico.
