Building Obsidian’s Sword from Steven Universe! This thing was forged from foam core and has a NeoPixel LED strip making it super bright. Customize LEDs colors and make sound effects when you swing in battle! |

It’s a bit over 3 feet (900mm) long and completely made from foam core poster boards. We used one 20x30 inch foam core boards to create this awesome sword! The handle, blade and components are detachable so it's easy to break down and travel with! We used Microsoft MakeCode to animate the NeoPixel LED strip! Codeblocks makes it fun and easy to learn how to program hardware with the Adafruit Circuit Playground Express.

The NeoPixel LED strip is press fitted into the blade with wires routed through the handle.
Alligator clips makes it easy to connect to the Circuit Playground Express!
We used a inkjet printer and vinyl cutter to make the details out of card stock!
