The challenge: this project focuses on bringing new life to the old toy that most everyone is familiar with.
So how exactly do you make a jack in the box "better"? Most people know what to expect, so they aren't surprised. But, if I change up what they think they know will happen - that brings the joy back to this toy!
I started out with an older jack in the box, but the song sounded awful and the release latch on the door wasn't great. So I bought a more modern one. I used an arduino and limit switch to monitor the state of the door. Inside I have a custom made compressed air chamber for the glitter/confetti. And finally, there's an air horn!
Here's a diagram of the basic layout of internals:
