Piezo Vibra Tab and the Prop

RSimonton

Just returned from UPEW, what a great time. Big thanks to everybody involved!

I purchased a couple Vibra Tabs at UPEW and the documentation shows a schematic for interfacing to a BS.

To interface to a Prop I assume I change the zener to 3.1V, what about the resistor size?
What max voltage is recommended for the zener, I see the piezo is capable of 70 volts.

Could you post the schematic for the BS interface? I have been trying to find the best way to connect the piezofilm sensor to a basic stamp.

Thanks!

It's on the Product page, (lower right):

Thanks. That is a pretty rudimentary hookup. I have seen some circuits that use op-amps. I was hoping to find·a circuit to provide some frequency filtering, etc.
