Collin's Lab: Homebrew Piezo
HTML-код
- Опубликовано: 9 сен 2024
- 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.

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
thank you for this
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.
just bought the ingredients after over two years of first watching it
How's that crystal you made 5 years ago working out?
@@Phelan666
Interested to know
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.
That is so cool. It's absolutely incredible how hard and smooth the surfaces are, it's like something manmade
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.
Hehe I like your collection of PCB masks on the wall
You should've tried inputting a signal to see if it makes any sound
umer salim I was anticipating him doing that too.
Yes. That's the whole reason for watching; I want to homebrew a piezo pickup for a guitar with nylon strings.
That big crystal seems a bit awkward for that purpose.
Then make it smolah
@@biggreentruck4907 you wouldn't need more than a strip of that. Generally piezos will go in the same slot as your bridge on a nylon. A little stick of it would work.
It should work but usually you might need an amplifier circuit depending on the amount of electricity generated
I left the computer for a few seconds and when I came back you were cooking tartar sauce. WTF lol
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.
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.
As a guitar playing chemistry student I was very entertained by this video
that was awsome, who would have know piezo's are so easily made, best vid I have seen in a long time
Bravo!
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!
Collin and kipkay are the best of make
Thanks by the lessons, Collin!
Thank you for your amazingly detailed uber nerdy video. I will be making my own piezo crystals tomorrow for a demonstration!
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:

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: ruclips.net/video/l_USYub3djY/видео.html
Dmitry Shintyakov how can I grow diamonds?
Toki Loki you can't unfortunately
Dmitry Shintyakov Any thoughts on growing crystals in a mold?
Collin! so glad I finally found this series! pondering Piezo for an idea I am working on!!
Collin is the reason i live to come home every day... lol okay, that may be a bit far, but he is awesome!!
Sequel please!
Next: Home made contact microphone!
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.
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.
I have made some great trigger circuits recently using piezos. i love them.
collin is the only reason to sub to this channel haha
Collin should start his own channel. It would be awesome!
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.
Colin's videos are great.
i think ill do it just for the awesome lookin' crystals!
his are fake if you look at ALL the other people doing it , theirs are small so he seems to be the Only one than can or can he?
@@emilee172 maybe he just dedicated more time to it
@@emilee172 you just proved your ignorance
Best pronunciation of "tartar" I've ever heard.
@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.
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.
Awesome! I'm making this just for the crystals, they look great!
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.
Now make's projects are becoming smarter and smarter :) neat video.
HOW FREAKING AWESOME
To make the contact mic, the crystal would have to be touching your thought so it can get the vibrations from your voicebox
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.
Collin should have his own channel.
What is that special ceramic? Let crystal cool between metal contacts for later.
There's a crystal that can produce energy from pressure or impact, that's beyond amazing.
ryan dorang Oh, thanks for correcting me :)
+3hornthrasher guess could say it transforms energy
This was awesome. My nerd antennae so excited to make this.
My junkie antennae so excited to smoke this 💨
Thanks for the great video I'll have to give it a try
Amazing! Collin's videos are always good!!
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
@tiagofumo with such videos you understand more of the way basic things work... so they're pretty helpful
you are the best, together with other people
THIS IS AMAZING!!
@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...
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
wow, thanks so much for the video. This is exactly what I'm looking for my project...
Pretty cool Collin !
Beautiful crystals!
Great explanation
i wish he would have applied a voltage to it... it would have been cool to hear such a raw material produce sound.
@amandaskapp Good question. the answer is no, your altitude and quarting of the recipie dosn't matter. what does matter id the cool down time. if the solution cools quickaly, the crystals formed are like what you got; thing and stringy. the trick is to lanthen the cool-down peroid. this can be acheived by making sure that the container is sealed, and even insoluated. this is to ensure that the solution has ample time for the large crystals you desire. hope it helps!
I wonder if I can cause impurities to make different varieties of Piezoelectric Lattice
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.
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.
Wow, awesome crystals!
your videos are the best !
It appears that Rochelle salt has a melting point of 75 degrees Celsius so you could hypothetically shape it into pretty much whatever you want to
OMG thats realy cool... thanx and merry christmas time from germany!
fascinating project, thanks for sharing these videos, cheers from san diego
Amazing explanation!
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?
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?
Tremendous stuff! I am going to have a go at that :D
Honestly, I just like the beats to his theme.
1. can u cut them to a certain shape when they're done?
2. how big can u make them?
3. how much power can they produce? most piezo ive screwed around with only get miliwatts when i hit them
4. this is AWESOME!!!
0:47 You found piezo amazing... I found YOU amazing :D
Yo mr.white this is art
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?
make a drum kit with it
Collins lab is awesome.
Collin is pretty cool.
Very informative video I want to try it to create piezo microphone for my violin 🎻 😀
@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.
Collin's Labs are the best! Has Make thought about making some sort of Chem Lab videos? Something "Golden Book of Chemistry"-like?
@theshiznojudge Piezos are used in the the sparker of a lighter...
GREAT DUDE ,NICE WORK
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.
btw the freq these produce is based on their resonant frequncy. the smaller the crystal, generally, the higher the freq and visa versa. i think. just fyi. Im trying to use these in a new project
@spiderobert I had the same problem. It formed a uniform, slushy solution rather than chunky crystals
@amsoil5 Thanks for the input! We tried this and also let the solution sit longer and got much better crystals the second time.
THIS was good content
how much pressure can a piezoelectric crystal can handle ??
Collin...why is this in 240p? OH, because youtube is still shitting on it....gotcha. Hey, love your work man!
@rampike74 - I'd have to do some quick research to give you a definitive answer but earthquakes most always have a pressure buildup in rock layers that then give rise to the piezo electric effect. Exactly how that translates into causing atmospheric rainbows I don't know for sure but it would seem that there is a connection. Rainbow streaks are often seen just before an earthquake occurs.
Light is a fascinating critter, as are electric fields.
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.
great video!
this is so cool, really very cool
Potassium sodium tartrate is hygroscopic...it wouldn't hold up in any practical application unless it was cut to resonate at a specific frequency then sealed in glass in an inert atmosphere. It was once used in microphones because of its very high sensitivity.
that is so cool .thank you .collin.
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?
while heating, inner pot should not rest on the outer pot which is very hot. May be one should hang the smaller pot i such a way that it remains partially immersed in the liquid, but does not touch the much hotter heating bottom surface of the outer pot.
This is the same thing im learning at school =D
The Great Pyramid was a piezoelectric power plant that emanated electricity like the "Tesla Tower". Discuss.
You can buy soda ash for a fraction of the cost from walmart or whatever store.
Its 3 bucks for a pound of arm & hammer "super washing soda", compared to 10 for like half a pound of it from jacquard
@vw77
nope. crystal structure is a specific, unalterable property of a substance.
