Eye-D Badge Catches Your Attention

Head out to your next corporate conference, and you’ll probably be handed a little paper badge in a plastic holder so people can learn what to call you (or whether …. Eye-D Badge Catches Your Attention. It serves a function, but it’s a little soulless.

[Aahan Sharma]’s Eye-D badge is a touch more interesting. At the heart of the build is an ESP32-C6 microcontroller. It’s a capable part, with clock speed configurable up to 160 MHz, and wireless connectivity baked in.

It’s hooked up to an 8 x 16 matrix of WS2812B addressable RGB LEDs, creating a color 128-pixel display. [Aahan] took advantage of the onboard Bluetooth Low Energy connection of the ESP32 to enable the display to be readily controlled by a smartphone, tablet, or laptop. It can be configured to display a name, social handle, or custom message as desired.
