I was playing around using an inexpensive alarm to make a sound reactive target. I named it the Banshee Target for the sound it made when hit.
As I was working on that "model", another idea came to me and I have had a few nights to work in it, so here is "Banshee Target 2.0".
The main "issue" I wanted to address with the new version was to extend the time the siren sounded, and that has been accomplished. The new version screams for 5 to 10 seconds depending on the power of the gun that hits it.

I dumped the alarms magnetic bar and substituted a strong magnet that I picked up at the craft store. It will shut the alarm down from a further distance, something that allowed me to have a bit more gap between the paddle and the uprights.
I intend to cover the uprights with a bit of strap steel to protect them from near misses.
I will also likely make a stand for this one like I made for the bell target.
This one really earns the title Banshee, it makes a really wild sound as the magnet swings back and forth before settling down!

Rod another great idea from you Bro., an really easy design set up to boot!! Still like alway's just one question? How is your magnet attached? I can't see any epoxy or any thing or is that magnet that strong as to stay in place.

Thanks Jay.
For now the magnet is just held in place with the magnetic force, it is pretty strong. The force of a pellet impacting the face only drives the magnet into the paddle - the backward force drives it into the back side of the paddle, the centrifugal force drives it down on the paddle's bottom "shelf".
The test shots from a 500 fps pistol did not cause it to move at all.
All that said, I do intend to epoxy it in place to avoid having it disappear during transport or handling, etc, just hadn't got it done yet.
Thanks

Another very clever one!

A great example of old school simplicity meeting new school technology! Great Job! What did you use for the target plate? Was it "off the shelf"?

EXCELLENT design and thanks for sharing!!!!
Happy Shooting!!!!

Thanks everyone.
Uncle Paulie - The target plate is "sort of" off the shelf. It is 1" wide galvanized steel stock from the rack of assorted steel and aluminum found in most hardware stores.
I cut off a length with a hacksaw, drilled the 2 holes for the eyebolts, and then made the bends using a bench vise and a hammer (a little redneck blacksmithing). If you look close you can see the hammer marks on the face of the plate.
So call it "off the shelf with a few field engineered modifications" ;^)

Great job, John, At some point, I'll probably put a couple of these together. I'm thinking one could probably find variations on these with somewhat different sounds. It would give the range a carnival atmosphere!

A couple of items.
First my plans to cover the uprights with some steel to protect them led me to another "DUH moment" that so often frequent my goofy projects. I suppose many of you foresaw this but were to kind embarrass me...
If I put steel on the front, the magnet sticks to it as it swings by....all together now "DUH!"
Two options I can think of right of the top - aluminum - readily available at the hardware store rack, or consider the uprights sacrificial, not much material there and not a big deal to replace them, just a few screws. Have to think on it.

Because there was not a lot of surface on the edge of the magnet to adhere to the paddle, I decided that epoxy putty would be a better choice. With the putty I can use that area on the back side of the magnet and much more surface on the paddle.
That's all for now.
