Overview

NeoPixel Sword

In this project we’re making a 3D Printed Energy Sword from the Halo video game series. Inside the blades are NeoPixel LEDs which are connected to an Adafruit Feather BLE 32u4 micro-controller.

A 2000mAh lipo battery will provide several hours of energy and can be recharged over USB. The blade is 86cm (34in) tall and the whole sword weighs just under 1 pound.

You can connect to the Adafruit Feather through Bluetooth. The Adafruit Bluefruit LE Connect app for iOS or Android lets you change the animation or color of the LEDs.

3D Printing & Cosplay

This project combines 3D printing and electronics to make a cosplay prop that's massive, yet lightweight and really bright. The sword is cut up into several pieces that are optmized for 3D printing. The handle and blades are thin and shelled to minimize the amount of material. The circuit is mounted to the inside of the handle, while the LED strips are nestled inside the dual blades. The USB port from the micro-controller is accessible for repogramming and recharging the battery, so you don't have to open it up.
