We all use WiFi-enabled devices on a daily basis. But you can’t actually see WiFi with your eyes. The Hertzian Armor aims to change that. It is a wearable device that scans local WiFi and makes it visible. The developers accomplished it using a WiFi sensor and LEDs.
An Adafruit CC3000 WiFi Breakout was used to scan local WiFi. The NeoPixel Strip represents the WiFi strength around the wearer. You can find out more about this project here.
