## Summary

Hackaday editors Mike Szczys and Elliot Williams discuss the Raspberry Pi 4's new 8GB memory option, driven by Micron's new chip availability and the need for desktop-class performance. They explore various hacks, including a scientific investigation into why solder smoke targets the user's face, a Python script for automating job applications using Selenium, and a crystal radio built on a credit card using its smart chip's diode. The episode also covers an Arduino-based drum machine with custom audio compression, a detailed RC tank model, and the lasting scientific impact of Cold War nuclear testing on modern materials and dating techniques.
