Kamui Cosplay has made a number of incredible props and costumes. We’ve featured her work on the blog before, but her portfolio keeps expanding. One of her latest builds involves Adafruit products: she made a replica of the Shadowmourne axe from World of Warcraft. She started by exporting a 3D file of the axe into Pepakura Designer. She printed the model and transferred the pattern to a thin, translucent PVC foil. She tackled the hardest part of the weapon first and then eventually attached LED strips and wiring to a light piece of balsa wood that fit inside the hollow axe form. She ran the LEDs with an Adafruit Pro Trinket 5V:
So here is the final build: The giant Arduino Uno was replaced by an Adafruit Pro Trinket 5V, the power source of a 6600 mAh LiPo battery got a PowerBoost 500c for charging and a tiny switch turned the lights on and off. To stabilize the super thin foil shell I added pillars out of balsa wood in between. On those I’ve placed the LED strip core and covered it from both sides with several layers of packing material to spread the light very evenly. In total I installed around 4 meters of LED strip with around 240 single LEDs on it. Everything was super professionally covered in tape and hot glue!
She goes over the steps in more detail in the above video.
