## Summary

Hackaday editors Mike Szczys and Elliot Williams discuss several hardware hacks, including a 770-potato battery built by Equala to power a low-power calculator, and a no-internet video chat system using Raspberry Pi and Trango software. They also cover Peter Livage’s method of using resin 3D printers to create PCB etch resist, and an analysis of Tesla’s driver-facing camera firmware revealing driver monitoring capabilities. The episode concludes with a look at a mechanical ball-bearing clock and an FPGA-based Gauntlet arcade game replica.
