Stormtrooper Voice Changer Helmet uses Teensy to Mangle Audio

Halloween has come and gone, but this DIY voice changing Star Wars Stormtrooper helmet tutorial¬†by [Shawn Hymel] is worth a look for a number of reasons.

In addition, the Teensy also takes care of adding the iconic Stormtrooper clicks, pops, and static bursts around the voice-altered speech. Check out the video below to hear it in action.

Besides a microphone and speakers, there’s a Teensy 3.2, a low-cost add-on board for the Teensy that includes a small audio amp, a power supply… and that’s about it. There isn’t a separate WAV board or hacked MP3 player in sight.

Good for him, but copyright issues aren’t what interests us here. The BBC clip showing him using a vacuum former to make the Stormtrooper helmet really caught our attention. A bit of further searching led us to find the thirteen minute video after the break showing the entire process, from sculpting the mold by hand, to forming the components, and the final assembly seen above. It’s a fascinating process that makes use want to build our own vacuum former (preferably on a larger scale than this one). It would come in handy whether it’s Star Wars, Daft Punk, or any number of other projects you’ve got in mind.
