Make the Ultimate Bluetooth Dry Ice Fog Machine

I recently needed a Dry Ice machine for some theatrical effects for a local show. Our budget would not stretch to hiring in a professional one so this is what I built instead. It's mostly 3D printed, controlled remotely via Bluetooth, battery-powered, portable and includes LEDs for fun effect. You can even design your own nozzle to create different fog patterns.I've included two nozzle designs of my own for you to try.

It works great as a stage effect and will be a hit at any Halloween parties.

If you prefer to follow an instructional video then I have created one which you can watch. It's also great if you want to see what this machine is like - I show both types of nozzles that I designed at the beginning of the video: https://youtu.be/IhL9i5he0LY
