allows you to interact with all your printers via the Cloud, and many other exciting new features.
This is a design for a 32" long cannon with room for a Neopixel "fuse", and a 4" speaker. Driven with whatever board you like, I am going with a PI for the easy audio. There is a hole for a reed switch to "fire" the cannon, which you can trigger by embedding a magnet in a torch or sword.
