I want to design such a headpiece because I want to find a way to include my night light as a part of my Halloween costume. Therefore, I decided to make this headpiece for psychics. The LEDs on the headpiece is gradually shifting from pink to green to match my crystal ball’s iridescence. And the NeoPiexl Jewel have a rainbow-color gradient.
One thing I would do differently if I had to do it again is that I will change the color of the NeoPixel Jewel. The color of the NeoPixel Jewel and that of the pixels are not matching very well and can be improved.
