Last night a passive shielded *undisturbed* raw piezo element inside a think metal Hammond chassis was producing 9.54 volts DC! That's the record as far as I know. Although I'm confident that such piezos when exceptionally undisturbed could produce over a hundred volts DC, but so far my goal has been in trying to ...

Lots of experiments lately. I built a piezo array consisting of 5 in-series, and then made 3 of those lines, for a total of 15 piezos. After the piezos had settled for awhile, the voltages were tested on *each* piezo. One piezo was producing 5.5 volts. ...

Today I connected the Radio Shack piezo element, part number 273-073, to a *highly efficient* red LED, part number TLCR5800. The piezo element was successful in lighting the red LED for ~ one second. I was in a dark room for ~ 10 minutes. I would describe the light intensity produced by the LED as being bright, and ...
