 Subject: Re: [OT] More on piezo-electric generation please








There is an old thread on this in the archives.  basically,
you need a 1-inch piezo speaker element, a diode, and a cap,
and you support the piezo between a couple of pieces of
flexible plastic, and put it in the heel of your shoe.  i
dont remember that anyone reported results--i have the parts
in a ziplock but never tried it.
