Blinking, fading, and color changing lights are a standard for eye catching goggles. This being said, I decided to change it up a bit and make a set that would engage the wearer in the production of sound.
As always I wanted my goggles to be interactive. When it comes to audio, I figured there was no better way to achieve this than with some sort of theremin which would invoke hand waving and finger wiggling from the wearer and anyone near by. Now, I realize that traditional theremins are quite complex in their inner workings and tend to run quite large, so I poked around the internet until I found this simplified optical theremin that requires a hand full of basic components and two 555 timers.This particular design also creates a very unique, annoying sound which in this application is perfect! Here is the link to the circuit I used : Easy Pocket Photo Theremin.
