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.
