Mini Siren
Here's my third mini siren, this one constructed from a cat food/tuna fish can and a smaller diameter tin can. It's being run off a model train transformer, and makes a pretty respectable noise. It's obviously much louder in person, but you still get the idea. Hope you guys and girls enjoy, and like I mentioned in the video, if you have any sort of requests or suggestions, just put them in comment form and I will definitely consider them. Thanks, and enjoy!
