Wi-Fi Security Analyzer

The Wi-Fi Security Analyzer is a handheld tool I built on an ESP32-WROOM-32 microcontroller to show how Wi-Fi networks announce themselves and how easily those announcements can be imitated. The finished device scans for nearby networks, listens to the signals every network broadcasts, and can stand up a look-alike network for a classroom demonstration. I assembled the Wi-Fi Security Analyzer from the ESP32 board, a 2.8-inch touchscreen, a micro-SD card, and a breadboard, then flashed open-source firmware onto the ESP32 and wrote the demonstration pages the device serves.
