So you would like to make your drone look like a UFO at night? Adafruit has just the project for you to try. It is all about 3D printing a custom mount to attach NeoPixels to a Phantom 4 drone. You are going to need an Adafruit Trinket, USB cables, 3D printing filament, and a few other simple parts to complete this project.
Adafruit has more information about this project here.
