## Summary

Hackaday editors Mike Szczys and Elliot Williams discuss a Tesla Megapack fire, highlighting the challenges of grid-scale lithium-ion battery safety and the massive water volume required to cool thermal runaway. They review several hardware hacks, including running original Tamagotchi ROM on an STM32 microcontroller, a flying wing aircraft design that replaces windows with LCD screens, and a troubleshooting case where a flipped RJ12 cable fried a Yaesu radio due to missing reverse polarity protection. The episode also covers using a laser to remove a Bayer filter from a camera sensor for spectrometry, emulating Transputer architecture with an RP2040, and software libraries for ESP8266 proximity sensing and Wi-Fi management.
