Air Raid Siren - motorized

Wanted a noise maker for my son's soccer games, and found a few of these sirens here. I made a hand cranked one, but never turned fast enough to make the noise. I combined the design of 2 sirens and added some of my own ideas, and came up with this. You can see the 2 things that inspired me in the remix section.

There is a video for assembling this thing, should be pretty simple. https://youtu.be/H9kh328obUw
