If you like electronic music, you’ve certainly admired Daft Punk’s glowing electronic helmets. While the originals are amazing, as shown in this Electronoobs tutorial, you can now make a very good replica for around $20 and 30 hours of print time.
Print files for the helmet itself are based on this Thomas Bangalter build by the Ruiz Brothers, and similar to that one, a good amount of sanding and finishing was needed to give it a metallic look.
Electronoobs’ helmet features seven WS2812 RGB LED strips, all connected to an Arduino Nano. Everything is controlled over Bluetooth by a custom Android app made with the MIT App Inventor, along with a microphone that allows the visor to react to music.
