Collin's Lab: Homebrew Piezo

Uploaded by makemagazine on Mar 11, 2011
Piezoelectric materials are about as close to magic as you can get. They turn physical pressure into electricity and can even turn electricity into physical pressure - an amazing sort of bidirectional converter for mechanical and electrical energies. Perhaps even more amazing is the fact that you can easily 'grow' your own piezoelectric crystals overnight using just a couple of common ingredients - awesome.

If you leave it under heat and pressure you can a singular crystal to make a sonic ear device.

Ha, the crystals have cleavage! Get it?
-
if it turns mechanical pressure into electricity will it shock you if you bite it? :D

@Nickillik How about a comb-over woman? LOL

Just grab a chunk of quartz and save some money

you should realy have your own channel ! :)

It converts physical pressure into electrical pressure, aka voltage. How do you convert voltage into watts/amps? It would be interesting to see how much energy could be captured from the vibrations of a generator, it could technically improve efficiency by capturing all wasted energy. Maybe combine that with thermocouples and capture the wasted heat energy.

Don't they use crystals like these for certain types of phones?

@coolguy701 for one... you can create a hammer system and add a butane tank to make an ignition system for a flame thrower... or attach it to an amp to create a mic... probably wont be the best quality though!

@legoclockfreak710 can you tell me what i can do with it? i really dont know.

i wish he would have applied a voltage to it... it would have been cool to hear such a raw material produce sound.
