In the weeks leading up to the Denver Maker Faire, I decided to design a case to hold an Arduino and the voice changer shield that I had designed. I wanted to make it easy for people to have a go at talking like a Dalek. It turned out to be a huge success!
The voice changer was connected to powered speakers inside the Dalek, and also connected to the LEDs in the dome. This did a pretty convincing job of making it look like the Dalek was talking.
Here are a couple of photos of the final case design.
I’ve uploaded the design to Thingiverse here for any previous voice changer customers who want to print their own case.
