This is my own take on a Unicorn Horn for baseball caps or any type of hat. I was inspired by Adafruit’s design of the same subject, but I didn’t want to see the tabs on the side of the horn where it meets the hat – and it was a bit fragile when printed (and small). So I set out to design a new horn and mounting system (initially for my daughter’s Halloween costume this year).
After many iterations, I found one that works very well. There is a mounting bracket that you attach first to the hat with a needle and thread (since this is on the “inside”, you don’t see any ugly mounting tabs). The NeoPixel 16 and the Gemma are in this piece (The NeoPixel just snaps into place without any glue – the Gemma can be hot-glued in place if desired). The result is a seamless attachment to the hat and a tight click-lock between the horn and mounting bracket. I created the horn without a sharp point, both for durability and to prevent injury if falling.
Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!
Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
