In this project, we’re upgrading the Halo Energy Sword (by Mattel) with lots of NeoPixel LED! We’ll tear it down and find how what’s inside. This cosplay prop only features 11 LEDs, leaving a lot to be desired. The stock lighting is underwhelming but we can easily modify it with lots of NeoPixel LEDs. In this project, we’ll tear it down and replace the LEDs with NeoPixel LED strips. We’ll wire up an Adafruit Trinket and power everything with the built in 3x AAA battery power supply.
