Eye-D Badge Catches Your Attention

A DIY conference badge called Eye-D uses an ESP32-C6 microcontroller paired with an 8x16 matrix of WS2812B addressable RGB LEDs to create a customizable 128-pixel color display. Controlled via Bluetooth Low Energy from a phone, tablet, or laptop, it can show names, social handles, custom messages, animations like an eye scanning the room or Nyan Cat, and even a freehand Draw Mode. The creator, Aahan Sharma, built a custom 3D printed enclosure with a lanyard ring so it feels like a proper conference badge rather than a random gadget.
