The horn contains:

  • Neopixel LED strip for vivid lighting effects

  • 18650 Li-ion battery for portable power

  • Teensy 2.0 microcontroller handling automatic color-changing animations

The electronics are fully enclosed inside the horn. From the outside, only:

  • a USB-C charging port

  • and a small rocker switch for power

are visible, resulting in a clean and minimal appearance.

Mounting & Stability

To ensure stability and comfort when worn, a reinforcement ring is placed inside the inner brim of the sun hat.
The horn is securely fastened to this ring using:

  • M3 countersunk screws

  • M3 brass threaded inserts embedded in the horn

This construction distributes the load and prevents deformation of the hat during use.

Features

  • Wearable LED display

  • Automatic color-changing effects

  • Clean external design

  • Secure mechanical mounting

  • Fully 3D-printable structure
