Sorry only 4 pictures allowed so I had to make another post.

Nice - now to see how they trigger. I had to go through some trial and error when I made mine. I used poron instead of felt to cut down on noise, but that also meant the piezo needed some wiggle room to make it more sensitive.

I just checked and mine have been going for almost a decade!

Hi to all.
I think they're pretty sensitive devices really.
I think I will get away with threshold and gain settings to get them working.
Again. That is of course what I hope.
If not I shall come up with the solution and implement.
I'll keep you all posted.
