    447: All Sorts of Weird Problems

    Chris Gammell, Developer Relations Lead at Golioth, explains how their platform simplifies IoT development by bridging constrained microcontrollers and the cloud using CoAP and Zephyr RTOS. He details the device-side SDKs for ESP32, nRF, and NXP, and discusses the business model of licensing the cloud software for on-premise deployment. The conversation also covers the shift in chip ecosystems, noting Espressif's move to RISC-V and the challenges of integrating Wi-Fi modules with low-power MCUs.

    The Custodial Arts

    Chris Gammell and Dave Jones discuss the Adafruit Feather form factor, noting its limitations regarding back-powering and pinout variations among vendors like Actinius and SparkFun. They analyze the new Nordic Semiconductor nRF7002 Wi-Fi chip, which lacks an integrated processor, and debate the complexity of building a countdown timer using discrete TTL logic chips like the CD4026 versus modern microcontrollers. The conversation shifts to the difficulty of sourcing TI parts like the TPIC 6595 shift register due to supply chain issues and inflated prices from third-party sellers, before concluding with a nostalgic look at obsolete test tools like the logic probe.

    Ep045: Raspberry Pi Bug, Rapidly Aging Vodka, Raining on the Cloud, & This Wasn't a Supercon Episode

    Hackaday editors Mike Szczys and Elliot Williams discuss the exhaustion of Raspberry Pi 4's HDMI signal interfering with its Wi-Fi, a power glitching attack on the ESP32 that compromises its encryption, and a hack that ages vodka in 30 minutes using an ultrasonic jewelry cleaner. They also cover Mike Harrison’s Supercon talk on LED consistency and gamma correction, the shutdown of Google Cloud Print and Best Buy’s IoT services, and the end-of-life of the Nest Revolve hub, highlighting the risks of cloud-dependent hardware.
