i've been trying to find information about the output of pvdf piezo elements in the interest of using a tube as an acoustic resonator (specifically a didjeridoo) that would drive led's when it produces a note. Unfortunately i haven't been able to find much. i was able to find a thread regarding the activation of led's with a piezo disc, and have looked over the schematic found here: http://www.discovercircuits.com/DJ-Circuits/door-knock.htm that was linked in that post, so i know the basic principle is possible. ultimately my question is whether a pvdf tube would be usable as a piezo element, and if so how would one go about connecting electrodes to it to run the led's...
any help is much appreciated.
