There are tons of foam or plastic replicas of the iconic Energy Sword, but tinkerers can make one that does more with less weight with the help of Adafruit’s guide. The company’s design uses 3D printed components and a pair of RGB LED strips to create a cool prop or toy.
The replica is based on Adafruit’s Arduino-compatible Feather microcontroller and its NeoPixel LED strip. The company also designed 3D models of the sword’s blades and handle; you’ll need to print the former with a translucent material so the light from the NeoPixel will shine through. Adafruit’s Bluetooth app will let you change the NeoPixel’s color and mode.
