Hi everyone. First post here. Excited about finding this place. I bet you can help me with this. I know very little about electronics, and don't even know anyone who claims to know anything, so here goes...
I want to mount a metal plate on a spring. When this metal plate gets hit by a projectile, I would like it to activate 12v power to run an alarm bell for a given time, maybe 2 seconds. It would be nice if the bell ring time would be adjustable.
I suppose I would want the vibration to be more than the slightest touch, but pretty sensitive. Maybe sensitivity needs to be adjustable with some adjustment pot.
Maybe I should be open to voltages other than 12v dc, as I've found some used 120v alarm bells too. Maybe the vibration switch and ring timer could use any voltage, and activate any voltage?
Also, if you have any ideas on maybe just hitting the bell once, really hard, with each distinct vibration with some kind of hammer, that would be cool too.
As few parts, as cheap and easy to order as possible would be preferred, as my soldering skills are severely lacking.
Here's some vibration switches I found... A "start"?

This is what I was thinking for the bell... The 12v DC models. Again, I would be open to having something strike the bell just one time too. Maybe have the option to do both?

I am thinking 12v DC for this project, as I think I'm going to want to power the system with 12v car battery so it's portable.
Thanks!
