I modified the procedure and got amazing results. To 120 ml water, add 80 grams cream of tartar (kroger brand use). Hold at 95 C in a water bath, adding 1 gram sodium bicarbonate (kroger brand) at intervals until all cream of tartar has reacted. Decant and filter with coffee filter. Pour fluid on ceramic plate. Add 20 ml of 99% isopropyl alcohol 5 times at 10 minute intervals. Let stand under a fan for 1 hour and 30 minutes. Longer may yield larger crystals, however these were sufficient for my purposes. Yield is approximately 90 crystals, 40 of which are large (1 cm or more) and uniform. Crystals have a clear appearance.

This type is easy for diy. But that does not make it a good piezo. Part of what makes a good piezo Is the amount of deformation thst happens for its mass in a given electric field. This piezo though works as a piezo, is not that good of a piezo.

Sweet! Can you grow a crystal between two metal plates? When using commercial audio pickups I found that diodes/leds flatten spikes from hard smacks. An opto-isolator can make a CMOS-safe switch. But those crystals use more exotic elements.

@Z-Ack Ай бұрын

I dont know how youd get crystals to bond to a metal other than by using an electrolysis style growth like how youd do with copper and silver.. to make a crystal form on two different pieces at the same time would be super difficult to make one with a structure sound enough to bond the plates or couple the plates together.. on piezo buzzers they just use the amalgam and drop the stuff on a disc, place leads on the disc and in the material and let the crystals form but i dunno what they use in top of the disc to electromechanically isolate the material from the metal disc..

The brownish color looks like impurities in the solution. You can get better crystals if you apply a recrystallization process first. Recrystalization. 1) After filtering the solution put it on heat again to evaporate off water untill you see the first crystal forming. 2) Then chill it to almost freezing so as to get the most crystals. 3) Take all the crystals out and put in just enough heated distilled water to redissolve all the crystals you have collected. Then let the solution cool and your crystals will be much more pure than the crystals from the start. Then to get a large crystal after recrystalization. 1) taking out a good crystal you want to use as a seed crystal and put it aside. 2) Then reheat the solution along with the poor crystals untill they have disappeared add a tiny amount of water if nessesary. 3) take the solution off the heat and shortly afterwards reinsert your good crystal as the seed crystal.

Crushing Randomizes the electric fields generated on crystal deformation. Net effect is no significant electric field as a whole. I dont know if this will work but maybe you'd have something if it is possible to align all the crystals in a binder with an externally applied electric field of thousands of volts. And, the binder would needs to be non conductive and have a low dielectric constant.

I believe if you let things cool down more slowly, and have patience, you'll get bigger crystals. I didn't have time or patience since this was for a school project that needed to get done, so I think I just used the fridge. A cool basement would be better. You can also try "seeding" with crystals from an already made batch. Here is a link to some very in depth info including how to make cream of tartar (I just used store bought): www.instructables.com/id/Make-Rochelle-Salt/

Pile your small crystals together, douse in ethanol. Ignite the alcohol and allow it to burn down. Allow to cool and the crystal will fuse together with slightly weaker pezioelectric properties. Crystal's will also be white and ugly.

@@nili8529 I have a flexible ice cream container with 8 piezo ceramic disks glued to 4 of the inner walls of the ice ream container. There is a hole drilled in the top of the container with a long dowel poking out. The dowel is attached to the floor of the container using a spring, the dowel acts as a wind vein. The dowel is connected to each of the piezos via a spring. the while thing is then setup[ in series and fed into a 24-5v regulator for charging purposes. With my current setup I have seen voltages around 21V @ 0.6A. I'm pretty sure I could charge 2-3 phones off of this at once. Runs on almost no wind. 3-4Km/h. if there is enough air movement/noise to move a blade of grass then this will work. I'm still trying to improve the design as the box I'm using could be a bit taller and I want to add some extra components like indicator lights and all that.

@kreynolds1123 Жыл бұрын

Electric spark lighters need sufficent voltage to cause a break down in the gap. That is roughly 3000volts per milimeter. Your piezo needs to make 1500volts to spark across 0.5 millimeter. Then you need conductive plates on each side where the electric field in the crystal can electrostatic induct electrons on the plate to move.

@kreynolds1123 Жыл бұрын

No! Piezo electric works by deforming a nondonductive crystal. The deformation moves electrons in the lattice just a little to one side. The collective effect is a measurable electric field. That field can then electrostatic induction (push/pull) on electrons in conductive plates similarly to a capacitor. When electrons in the plates are allowed to flow in a circuit, they will eventually equalize. Once the plate's field equalizes the crystal's field, there's no more voltage potential between the plates.
