## Summary

Hosts Elliot Williams and Dan Maloney discuss the release of KiCad 8, highlighting its new library team, version control integration, and growing adoption in the open-source hardware community. They review several maker projects, including a solar-powered water heater using water as thermal storage, two different e-ink weather stations utilizing the BMP180/BME280 sensors, and a wireless telescope guidance system built with ESP32 and AS5600 sensors. The episode also covers technical deep-dives into I2C pin-muxing on ESP32, Power over Ethernet (PoE) standards, and the potential implications of room-temperature superconductors.
