Just curious if anyone has ever cracked open a old smoke detector/fire alarm and used the round metal piece as a piezoelectric by wiring it to a patch cord and jack? If so how did it turn out as far as sound quality? Thinking about giving it a try.

I read this article years ago and have seen othets about taking the round piece of metal inside a smoke detector & wiring it up to a patch cord and jack ,wedge it in between the neck and lid top and I thought what a Great Idea. I got a carbon monoxide detector and its round metal disk is a little bigger than a bottle cap ,by just a little ,so I figure it will be plenty big enough to get a good sound out of ,just haven't tried it w the carbon monoxide detector and Piezoes are fairly cheap ,but I just thought "what a good Idea". There was also a article about cracking open a smoke detector for the same use in Guitar World not to long ago.
I got to toss a wet blanket on this one folks. What makes a detector work is a small radioactive plate, This plate is safe until you physically touch it. Piezos are cheap enough not to put yourself in harms way.
Yeah ,if you would lane let me know how everything works out and "Wayfinder" Thank for the heads up on not going with one too small. Makes since and I have always thought you get the best sound out of a piezo by sandwiching it between the neck and lid. Thanks guys for the advice and lane ,Let me know how the window alarms work for you ,again Thanks guys!
I've got some I pulled out of magnetic window alarms. They're a little bigger than a bottle cap. I'll let you know about the sound once I get one wired in.

This is pretty cool idea.
