## Summary

Hackaday editors Elliot Williams and Mike Szczys discuss several hardware hacks, including a project by I am pro that uses an ESP32 and Gerbil firmware to turn an Etch A Sketch into a camera. They also cover a submarine built in a lemonade jug, a teardown of the new Amazon Echo Dot, and a tutorial on debugging op-amp distortion in an Arduino walkie-talkie. The episode concludes with a deep dive into the complexities of USB-C standards and an analysis of Michelin's airless tire technology.
