Sound To Electricity

[DreamThinkBuild]

Hi Wings,

Actually I have some metal tube wind chimes on the side of the house mounting a piezo-speaker inside would be a good test. Although the only time I get wind around here is when it storms.

Hi IotaYodi,

Thanks for the suggestion of using water. I have a large stainless steel mixing bowl I picked up from a tag sale. I can fill it with water and try. Should resonate pretty good with a solid hit.

@All,

I stumbled across these little vibrating disk motors(3vdc 80ma draw,running around 12,000 rpm).

Something to try with these little vibrating motors would be to sandwich it between two large piezo-speakers.

Could a modified Joule Thief, by stepping down the voltage through a secondary, run these little motors?

peizos are different, in that they are "reversable".
unlike normal speakers, which would waste a lot of energy trying to use them as "recievers".

its interesting to hear that peizo speakers work better than an actual microphone. i'll have to look into this.

rochelle's salt can be grown at home, into whatever shape and size cryatals that you want. im getting pretty good at manipulating the crystal growth,. perhaps we can design our own "custom" peizo reciever/generators......

and for the Tesla fans out there,. those little vibro-motors can be Dangerous (heh heh heh)
