In this episode of element14 Presents, Mark builds a DEFCON-style status display using an ESP32 and addressable LEDs. Originally intended to track global alert levels, the project was reimagined as a personal progress indicator that changes color based on task completion. The ESP32 hosts a web-based interface where users can manage tasks, with the LED sign reflecting their status in real time. This project combines simple electronics, custom laser-cut acrylic housing, and Wi-Fi control for a practical and adaptable build.
