Doing these projects in my parents' basement as a kid was such a formative experience. Much gratitude for the positive educational impact you've had on people like me.

With some careful cutting, grinding, and polishing along it's crystalline axis, you can both increase usable surface area and tune frequency

He could make it a lot better if he took what he had, selected a seed, and recrystallized around it in an insulated container. That will give him bigger, more perfect and more pure crystals to facet.

@@AtlasReburdened Also, crystallization seems to have happened too quickly. The liquid was too concentrated. Would be better to dilute it, dangle in a seed, and let it evaporate slowly over a few days. Also, use distilled water to minimize contamination. Metal salts in tap water will totally ruin the crystal structure.

@@rich1051414 Indeed, I suggested an insulated container to slow the process, but it would probably be easier to go your route and just start with a lower concentration. Also yes, distilled for sure. Personally, I would take water from a freshly serviced Glacier refill machine(because I've tested a few and when they're freshly serviced they put out 4PPM water) and run it through a clean, ungreased, glass distillation rig with a heated(but obviously not to boiling) receiving flask. That should give the purest water anyone can have access to outside of a lab that specializes in 0PPM, dielectric grade water. At that point, it would probably be wise to do the crystallization in a container that's capped with a fresh carbon filter to prevent airborne volitiles from absorbing into the water.

Thank you guys that helped me a lot. @Zeek is it possible to cut multiple Piezo Crystals out of a very big one?

Dude - you're a legend. This was as good as when you made an homebrew LED.

That is so cool. It's absolutely incredible how hard and smooth the surfaces are, it's like something manmade

That is close to one of the coolest things I've seen in a long time. I would think that to make a contact microphone you would need to start by being able to cut a really thin slice from the crystal and give it a really high polish.

just bought the ingredients after over two years of first watching it

Thank you for your amazingly detailed uber nerdy video. I will be making my own piezo crystals tomorrow for a demonstration!

Thanks Colin that was great, my kids will love it and I can use it to teach them about Pierre and Jacques Curie the discoverers of the piezoelectric effect.

Just when I thought I have seen all the Collin's Lab videos I find this one. Better late than never. I miss this series of videos.

I have made some great trigger circuits recently using piezos. i love them.

It should work but usually you might need an amplifier circuit depending on the amount of electricity generated

Wow, That's cool, I made some crystals years ago, but the recipe instructions said to hang lengths of thread, and the crystals grew on the treads, "IT WORKED" But the way you Show it here is Much better & easier too I think, & I am going to give it a go. thanks. Thom in Scotland.

Bravo!

Amazing! Collin's videos are always good!!

Awesome! I'm making this just for the crystals, they look great!

The oilfield used Piezoelectric crystals in their tools to pick up Gamma Rays given off by the formation. Depending on the type of formation, it gives off different signatures. Limestone/Dolomite gives off a very LOW count even lower than what you would find in the Background radiation at surface = +/- 30 counts per second[API]. Whereas sand is typically between 30 - 45 counts, and shale is much higher 65 + counts. The crystal glows when hit with the gamma rays, and the light is measured.

Colin's videos are great.

that was awsome, who would have know piezo's are so easily made, best vid I have seen in a long time

Collin! so glad I finally found this series! pondering Piezo for an idea I am working on!!

Seal it between two thin resilient surfaces (conductive) before it dries. The disk piezo uses a similar method where the crystal forms after the disk is sealed.

@tiagofumo with such videos you understand more of the way basic things work... so they're pretty helpful

Beautiful crystals!

wow, thanks so much for the video. This is exactly what I'm looking for my project...

Collin and kipkay are the best of make Thanks by the lessons, Collin!

Wow, awesome crystals!

To make the contact mic, the crystal would have to be touching your thought so it can get the vibrations from your voicebox

Amazing explanation!

fascinating project, thanks for sharing these videos, cheers from san diego

Thanks for the great video I'll have to give it a try

THIS IS AMAZING!!

@themvp007 - you'll find one as the on-board speaker on at least some modern PC mother-boards. The crystals have a natural resonant frequency too, and just like ringing a bell, the larger the crystal the lower that resonant frequency is. Other crystals can also work. They also put out a voltage just from pressure. Squeeze it with a pair of pliers (not too hard now). This electro-/mechanical effect may explain the strange behavior of animals and rainbows before an earth-quake.

Great job Collin, thank you for sharing this knowledge, Is it possible to grind it ? Should I take the orientation of the Crystal Latis into a count?

i have a request for you please make a video on LDR and explain it like you explain in make present the multi meter,make present the ohm law etc ok thanks.

What voltage are you producing? I have an experimental design that I want to test but I need a fair amount of voltage to make it work.

@amsoil5 Thanks for the input! We tried this and also let the solution sit longer and got much better crystals the second time.

Pretty cool Collin !

Cooling of the hot saturated solution produces crystals very quickly, but they have much defects. If you re-dissolve these crystals in pure water and them let it evaporate slowly, that's what you can get: plus.google.com/photos/116542359168957860292/albums/6071596141873389857

Beautiful crystals, I haven't messed with Rochelle salt since my main thing is growing large Monoammonium Phosphate crystal clusters. www.pinterest.com/bartlett1710/ I started around April of this year and my oldest crystal now weighs a lot and the individual crystals are an inch across. I just had to move it into a five gallon bucket because the side crystals had grown flat against the 2.5 gallon bucket. I have grown large batches of single Copper Sulfate crystals as well as large clusters that only look nice because I glued clusters together before letting them grow together. I am having a big problem with what I thought would be the most beautiful specimen: a sphere with crystals growing outwards. I believe the fluid dynamics of the way the crystals grow on the sphere is interfering with it's progress. I had used a matrix of compressed rock with a hole drilled through so it could be supported on a stand. I then made a device using a simple coat hanger that has the specimen rotated 90 degrees so it is horizontal and free turning so (in theory) as the crystal growth on top gets heavier it will turn allowing the rest of the crystal equal time on top. Your crystals are beautiful so you must be good at what you do. I am having a large problem getting my specimen to 1. grow equally 2. get any larger than 3-4 inches in diameter and need a little help.

Konichi Wawa My crystals are small, I have never grew any bigger than 5 cm. But, as far as I know, one of the methods for growing big crystals involves artificial circulation of the solution. There are different ways to do it: rotate the crystal, teether the growing tank etc. Here, they use rotation: kzread.info/dash/bejne/npOJtbuukpbKmrw.html

Great video would you consider a video on ceramic pezio electric crystal? How do they work and made?

As a guitar playing chemistry student I was very entertained by this video

Awesome tutorial, thanks alot

Maybe you could hook the crystal up to a transformer/regulator to boost the voltage with a diode in between. This seems like it would up the voltage, and thusly sensitivity, of the piezo.

Great explanation

your videos are the best !

Whenever I watch Collins videos I'm just like "Huuuh, Duh I didn't get it" but he does make good things and thats where Kipkay comes because his projects are fun to do and easy to make!

Looks like the output consists of complex transient currents. Impulse and oscillating dampening waveforms. This is not necessarily an A.C voltage as the impulse wave does not oscillate back and forth, but rather pulses in one direcrion; more similair to a d.c output. This makes me think that a piezoelectric crystal could be used in place of a spark gap or vacuum tube if someone was to build say a tesla hairpin circuit, or some kind of mechanical analog to that.

Fantastic. Thank you.

by the way if you apply heat to sodium bicarbonate you get sodium carbonate and it is very useful if you cannot find any soda ash

I left the computer for a few seconds and when I came back you were cooking tartar sauce. WTF lol

great video!

Very informative and easy to follow! Why don´t you cast the liquid into a diamond or crystal shaped form and let the whole batch become one large solid crystal?

Sequel please! Next: Home made contact microphone!

Collin is the reason i live to come home every day... lol okay, that may be a bit far, but he is awesome!!

that is so cool .thank you .collin.

does the crystals break easily?... :o

Maybe and yes. The maybe being that the output voltage would not be as consistent because it would be as if you were hitting multiple crystals at the same time. it would produce a noisy signal. But for pure asthetics, yes it would work great for that.

Question: Can I powderized it and make a disk? TIA

Love your videos !! :D

WOW! thank you very much, im making a DIY drum set and drum module, and ive been experimenting with piezos alot, so i can recieve cool and weird signals to convert into sound, this homebrew piezos crystals gave me tons of ideas to work with, btw: if you apply electricity to the crystal does it make a sound o vibration?

It works just like a regular speaker, but instead of using the movement of an electromagnet through a permanent magnet to move the diaphragm, it uses the changes in size of the piezo crystal

Thanks for the demo. Have you tested any of these Rochelle salt crystals to see if they change shape/deform when voltage is applied? I would be very interested in knowing if it does, and to what degree. Thanks.

Collin should start his own channel. It would be awesome!

Now make's projects are becoming smarter and smarter :) neat video.

this is so cool, really very cool

@mastigoz Applying a dc voltage won't create a sound it will just deform it slightly, but applying an ac voltage like the one in musical signals will vibrate it and create sound similar to a speaker...

if the ceramic changes shape when a current is applied, would a crystal shatter?

Awesome video. Now I'm going to have to try this :D

Good job

Amazing crystals

I have an ultrasonic cell disruptor. In the manual they tell you that the frequency of the horn, has to match the frequency coming from the power supply. They are set by the manufacturer. If they do not match, they say that the power supply will fail. I am wondering what determines the frequency of the piezoelectric crystal inside the transducer horn? Does the geometry and size of the crystal determine it?

@ky5666

3 жыл бұрын

It's the size and shape determining the resonant frequency. Much like the size of a crystal oscillator determines it's frequency. Not sure about the damaging power supply part. Maybe drawing too much current if it's not close to resonant?

WHAT IF. when letting it dry overnight. you allow it to dry inside an electric field? will it somehow change the orientation of how the crystal will be formed?

very interesting...thanks

in metric units it´s about 2dl of cream of tartar in the same amount of water and 177 degrees Fahrenheit is about 80 degrees celsus

If you can't find soda ash check the craft section at a local big box store I know walmart has fabric dye that is mostly soda ash also this is the easy way to make colored crystals.

@flahr1 No, I meant, would it still create voltage even if you just held it and whacked it? By the way, a small voltage can still shock you, it will just not hurt much.

can you please do more with this. like have it make sound or something?

If you added an ac current would that cause the crystal to change shape or vibrate? Also while its cooling do you think if you exposed it to a sound frequency it would crystallize into different patterns?

Amazing!

if you apply electricity curent to the cristal will it make sound ?

are the cristals hard to break?I want to make some :D

Ahmmm, is there a signifcant effect in diferent sizes of crystal? Like does it increase voltage if the crystal is largr in size?

If you wanted to use this voltage in a circuit, for example, you'd have to make a transducer, right?

Hi. The weather is a bit hot in Buenos Aires, Argentina. Donyou think i showld put the mix in the fridge?

That is amazing.

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.

Could you use these crystals to produce a spark, such as the ones from piezo igniters.

I made the solution just as done here, and it didn't create crystals overnight. I've seen other people make these, and they said it took over two weeks for the liquid to evaporate and retrieved the crystals at that point. I'll just keep mine in the dark for a few days.

hi colin! if these crystals can create a voltage/charge, would be also able to charge electrical appliances with these? Or is the power output too small?? thanks!

How many ml of water do you use? and do you try to retain the temperature of 180 °F by heating the water constantly ? or do you discontinue the heat supply when it has reached the mark of 180 ° F? Thanks :)

should we wear a mask or have good ventilation with this or can it be done safely in the kitchen even with family present? is there any risk of fire or explosion that are a direct result of this experiment?
