Hacking a jack in the box

The air horn on this project was fun, but I think it could be simplified a lot. This horn takes up a lot of space and is complicated. I think I could use a small electric siren/alarm to replace it with.

I ran into a lot of issues with the confetti blaster. You have to pump it up right before it's used, it's large and it's overly complicated. I think for version 2.0, I'd used something mechanical to increase reliability and save a lot of space.
