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.
