 Hey what's up folks, in this project we're making a Chaos Emerald inspired by Sonic the Hedgehog. These emeralds are 3D printed and feature Neopixel LEDs and Adafruit Circuit Playground. We designed three different sizes so they can be made on a wide range of 3D printers. There are two halves that snap fit together and have a special mount for the circuit playground. A 500mAh LiPo battery is hidden underneath and plugs directly into the board. The LEDs are nicely diffused making the whole thing light up nice and bright. With Circuit Python you can easily customize the code to make the LEDs have different colors. If you have the circuit playground bluefruit you can use the mobile app to change the color of the LEDs over bluetooth. The color picker lets you change the colors and brightness so you can easily adjust the look of the emerald. We think this is a great way to control your props without having to take them apart. Circuit Python makes it easy for folks who are just getting started and looking to get their projects quickly up and running. The emeralds are 3D printed without any support material using translucent PLA filament. It's often called natural clear or Avery white but it's really the translucency that makes good diffusion. The battery is placed inside the 3D printed mount in between the standoffs. The board snap fits into the mount with the tabs grabbing onto the edges of the PCB. A separate bracket is attached to the mount using screws and hex nuts. The bracket is placed over the standoffs and gets secured with additional machine screws. This keeps the board suspended inside the emerald and allows the light to spread. The bottom half can then be lined up with the top half and they just snap fit together. We hope this inspires you to check out Circuit Python and Adafruit Circuit Playground. Thanks so much for watching and be sure to subscribe for more projects from Adafruit.
