piezo choices and specs?
« on: April 11, 2012, 05:38:07 PM »
Most home builders use the Radio Shack piezo transducer  #273-073A and the specs are on the package. Have any other builders found other piezo offerings workable and
wondered about the specs? Operating temp seems a funny spec but as a buzzer maybe not. Still is anyone going to do a two hour buzz roll and heat the neoprene overlay beyond 140 degrees? (at which point
the piezo will do what- warp?
Mouser electronics lists about five disk piezos at workable sizes  15mm to 45mm with varying specs.
   I bought one of the first Drum Workshop's kick pedals in 1990 I think and pulled out a massive 1 3/4ths inch piezo embedded in the rubber impact stanchion to see how it worked.
There was also a pot on the pedal for sensitivity. Never did adjust it- just used the features on a midiKITI for the best results from the incoming pulse.

When I was into making my own triggers I found piezos online that were much smaller than Radio Shacks and more sensitive. I never really looked at specs. I went by price. They were much less expensive.
