Vox Imperium: Stormtrooper Voice Changer
The Empire's finest have a distinct nasal and mechanical voice when talking through their intercoms. As you work diligently on that Stormtrooper costume and apply for the 501st, you can up your armor game by including a voice changer.
There are pre-built solutions available for budding Stormtrooper cadets, but most are bulky and sometimes require wiring outside the helmet. However, with a little bit of coding and wiring, you can build your own inside a helmet using SparkFun parts.
In this tutorial, we'll build the voice changer on a breadboard for testing. Each helmet will be different, so the wiring will have to be adjusted. The parts list below details what you'll need for the breadboard prototype.
Note that from the resistor kit you'll need:
- 1x 2.2kΩ
- 1x 4.7kΩ
We suggest you be familiar with the following before embarking upon this tutorial:
