## Summary

Hackaday editors Elliot Williams and Christina Panos discuss a range of hardware hacks, including a project to decode VHS tapes by digitizing raw RF signals for archival purposes, and a series of student projects using the ESP32 microcontroller for tasks like image recognition and EMG-controlled robot arms. They also cover an nRF52840-based keyboard, a GitHub-integrated OTA update system for ESP32s, and a deep dive into the engineering history of the 'TV Guardian' closed-caption censor device.
