Strictly speaking, it handled 1,000v *at the higher frequencies*; but at the sub-1k range it started to complain, and below .5k started to self-destruct. Interesting vid. Thanks.
I love this video, the resistor goes like: what the hell is going on? While the piezo was being strafed by no one and making some DnB live beats, love it.
I think the snapping is caused because there was considerable DC bias, which is something else which should be avoided. Connecting it to +1000V, with a resistor in parallel and a MOSFET to 0V will give it a DC bias of 500V. Try running it of 1000V peak to peak, by connecting a capacitor in series with it and a higher value resistor in parallel to minimise the effect of the capacitor's leakage.
oh one other thing is arch eye which can make you go blind and hurts mre than a stab in the back also sparks mean hot flying microscopic or nanoscopic fragments so be sure to use goggles
Classic David vs Goliath, and our humble subject fared quite well. In fact you got some music as well as a pyrotechnic light show, which is a good "bang" for the buck (pardon the bad joke, I'm a punny guy)
'ol sparky there seems to have went on to the big Piezo transducer heap in the sky..It had some potential to make a good mini-popcorn popper there for about 30 seconds or so...lol !!
Yeah, I was impressed by the 'fet. It's an IRFPG50: www.digikey.co.nz/product-search/en?KeyWords=IRFPG50PBF-ND&WT.z_header=search_go 1000v, 6.1A, so pretty beefy for its size. I'm thinking about using it in a boost converter.
Yeah, some of the specs on HV silicon get pretty silly. I have some 30kV rated diodes that have a fwd voltage drop of 47v. Had me scratching my head when I tested a rectifer bridge with 'only' 240v and was getting hardly anything out of it.
Hello gristc, you feed the piezo a frequency, which voltage it was at could you confirm the evolution of the voltage at the piezo in function of the frequency? Look it was more destructive in the low frequencies, did it mean that the voltage was greater at low frequencies?
Khwartz You are right, it was much more destructive at low frequencies, but the voltage was the same. I think it was mostly because at the lower frequency the voltage is applied for longer periods at a time. I was feeding it a square wave. My method was to find the natural resonant frequency of the speaker, which turned out to be about 3500Hz. Initially I set the generator to that and just turned up the voltage to 1kV. When it wasn't doing much I started dropping the frequency, but left the voltage at 1kV. The lower I got the more arcing I could see.
I say it still good! Because Car Audio Don't Reach 15 or 24V! Using 2.2 uF Capacitor It Should Handle Lots Of Power Because Bass is mostly amps that are blocked
gristc I mean that at the same voltage, the piezo begins to crackle only by lowering the frequency. So an high pass filter may avoid the risk of break.
It just looks nice, all the sparks are already like small fireworks, but what I really like are all the little electric arcs, like there is opening a gate to an other dimension xD
I have one of those... was just wondering what it's used for (didn't get that far in class yet)... Thank you for showing me what not to do with it... lol
+Majestic Word Also, if you put a square wave across them they will vibrate at that frequency. They are often used as cheap buzzers in toys and other things. Musical greeting cards also use them.
+William Nah, most speakers are a coil of wire and a magnet. These piezo speakers are often found in children's toys and other places where you don't need much volume and have limited space.
+gristc piezo tweeters are also found in tower speakers, mostly cheap party ones but also good ones. the piezo coin is attached to a paper Diaphragm and a horn to make it louder. the biggest problem with them is the 5khz exaggeration and the high harmonic distortion. that why they are only used above 7khz in good speakers. in cheap speakers they are mostly used in unfiltered 2 way combinations thats y they sound so awful.
3:38 that snare solo, though XD
wish there was a HAHA button or emoji, that is the best comment
LMFAO
The piezo made some sick beats.
Your pfp is awesome
@@JMNTLRDRX thank you :)

That was the coolest firework show ever.
I love this video, the resistor goes like: what the hell is going on? While the piezo was being strafed by no one and making some DnB live beats, love it.
I like my tweeter highs to sparkle... this video kinda redefines that term. lol
thank you for this video...now I finally understand creation of everything we see in nature...
lmao
in reverse
3:11 "YOU PUT 1000 VOLTS THROUGH ME! I. AM. *SHOOKETH!*
poor thing. you sadist.
+Iggytommy You're right. I did enjoy doing this. 3:^}>
gristc - pervert. :p
hmm what
This made me laugh really hard. Thank You!
I would really like permission to use this video. It's a brilliant demonstration of the reverse piezoelectric effect.
Heh, I didn't set out to make an educational video, but sure. Just credit me, I guess. :)
Haha loved it, fun!
Rust in peace piezoelectric
This is one of the most important videos on Crystal destruction online.
piezo beep sounds like Nokia 3310 tones.
Writing an important exam tomorrow about macro economics. How is this going to help me??

Cheaper than fireworks!
Now it's a piezo taser
Reporting the video as Child Abuse and Violent Content.
Umm, ok?
Man, that was cool!!!
If hotwheel cars had anti lag for their turbos
Interesting. I had a bunch i used to try and make a record cutting head, they often failed at just under 100v.
very very very gooooooooooood
This made me satisfied very much. Love the popping.
3:31 nice blowing speaker
oh one other thing is arch eye which can make you go blind and hurts mre than a stab in the back also sparks mean hot flying microscopic or nanoscopic fragments so be sure to use goggles
hey, try to put this pieso betwen two iron core of 50 hz electromagnet. The core vibrate and pieso produce a voltage.....good luck!
Its just I am watching a firecracker explosion show
Piezo speaker can produce music but if you put electrical current it makes a bass noise
It turned into a taser close to the end XD
Haha, "oooh yeah!".
Classic David vs Goliath, and our humble subject fared quite well. In fact you got some music as well as a pyrotechnic light show, which is a good "bang" for the buck (pardon the bad joke, I'm a punny guy)
RIP Piezo😐
I searched for this gold.
reminded me of pop-corn machine ;D
Thanks for sharing.
'ol sparky there seems to have went on to the big Piezo transducer heap in the sky..It had some potential to make a good mini-popcorn popper there for about 30 seconds or so...lol !!
sweet, im surprised the mosfet survived! looked friggin awesome as it broke down, what mosfet was it ? interesting!!!!
Yeah, I was impressed by the 'fet. It's an IRFPG50: www.digikey.co.nz/product-search/en?KeyWords=IRFPG50PBF-ND&WT.z_header=search_go 1000v, 6.1A, so pretty beefy for its size. I'm thinking about using it in a boost converter.
gristc damn, RDS on 2 ohms. jeepers. i guess at 1000v its less of an issue. thought of using IGBT instead of MOSFET for a boost converter?
Yeah, some of the specs on HV silicon get pretty silly. I have some 30kV rated diodes that have a fwd voltage drop of 47v. Had me scratching my head when I tested a rectifer bridge with 'only' 240v and was getting hardly anything out of it.
I love this video
you deserves even more subscribers
wow It became much louder at low frequencies.
That popping reminded me of strobes.
What is that little pizeo speaker 🔊 made of? Appreciate your curiosity and research. Thank you for sharing.

Good, and Very Thanks for these specifications, it clears me well the idea :) Thanks again for the sharing :)
+gristc I think the arcing is due to movement, so on high freqencies, due to inertia, it wont move as much as on low frequencies.
+gristc actually the voltage was lower, since piezos have capacitive impedance behavior. i think it moved to much and physically broke.
Just don't touch it or you'll be saying "that really fucking hertz!"
From 3:34 gives a cool electronic rhythm
at high frequency at 1000v there should by arc
It made me feel thor when I saw the electric sparks flowing towards centre.....oooooooooo
2:41 Sound like my panel:4002,4100ES and 4208
I say it still good! Because Car Audio Don't Reach 15 or 24V! Using 2.2 uF Capacitor It Should Handle Lots Of Power Because Bass is mostly amps that are blocked
Para un altavoz cuantos watios aguantaria..?
The music starts at 3:11
I have the same multimeter!
lol!! TOAST! the disc was damaged prior however!
could you fix that using Electrocote.
Interesting... That's why to use an high pass filter in speaker systems
I'm not sure what you mean. This has no relation to frequency filtering. Just a bit of fun with high voltage. :)
gristc I mean that at the same voltage, the piezo begins to crackle only by lowering the frequency. So an high pass filter may avoid the risk of break.
The only time these things are making any loud noise lol
Great!!! i love it!!
3:49 Sounds like Gene Hooglan!
Heh, I had to look up who that is, but you're not wrong. \m/
Now you see what happens at Tesla luckey numbers AWWINSPIRING
Sounds AND looks like its getting a tattoo 🤣🤣
Very interesting, I'm going to have to try that for my own very specific and interesting reasons.
What did you use to generate your frequency?
I have a Rigol DG1022Z frequency generator.
you should try 10kv
Cool. Thanks.
I suppose it has a slightly lower rating.
How is your Mosfet still alive :-)
Cool.
3:00 is that the famous popcorn song?
2:49 what happened to its color
+Shaheer Syed Nothing too exciting, I think I moved my arm over it or something like that. The outer ring is quite reflective.
now it's broken and it blow ups
i think its boken ! ; )
3:37 drumset mode
awesome work man :D
Firework show @3:15 :) Thank me now?
Thanks again
@3:45 looked like its just alrady shot by kim j.
I might sample this sick beat
where is schematic for drive circuit?? can you help me and show me how you are driving this please?
I just used a very simple low side MOS-FET switch with a cascade multiplier for the drive voltage.
Anybody tell me how to make the piezo discs ? Pleaseeee
This was extremely satisfying to watch for some reasom lol
It just looks nice, all the sparks are already like small fireworks, but what I really like are all the little electric arcs, like there is opening a gate to an other dimension xD
it did a beatbox😂😂😂😂
Oddly entertaining....
Cool
i know that's a speaker cuz there's a voice coil
would love to see this in slow motion
Hmm, now that you mention it, so would I. Added to the list. :)
Best music
What was the purpose of that experiment?
Someone on Reddit asked how much voltage one of these could stand so I wanted to find out.
it produced nice beat, hehe ...
great great work! lololol
You reached the dielectric breakdown voltage. That's not so safe :/
It depends on your definition of safe. I didn't die or even sustain any minor injury.
Doing something stupid like touching it however...
Gotcha
we saw 3 cats, one was on lsd 3:14
To valhalla!
I have one of those... was just wondering what it's used for (didn't get that far in class yet)...
Thank you for showing me what not to do with it... lol
AWESOME... I have one of those also... now I can take it apart! :~D
+Majestic Word Also, if you put a square wave across them they will vibrate at that frequency. They are often used as cheap buzzers in toys and other things. Musical greeting cards also use them.
cool, I will try it in class on Monday...
thank you both!
i think those are called whistle chips
Those?
thats what i learned to call them
3:43 it sounds like someone is shooting the piezoelectric element and can see blue stuff. (That's the electricity)
There is one in every speaker, right ?
+William Nah, most speakers are a coil of wire and a magnet. These piezo speakers are often found in children's toys and other places where you don't need much volume and have limited space.
I guess that piezo material isn't as precise as the coil wire/magnet combinaison. And even, costs more maybe
+gristc piezo tweeters are also found in tower speakers, mostly cheap party ones but also good ones. the piezo coin is attached to a paper Diaphragm and a horn to make it louder. the biggest problem with them is the 5khz exaggeration and the high harmonic distortion. that why they are only used above 7khz in good speakers. in cheap speakers they are mostly used in unfiltered 2 way combinations thats y they sound so awful.
to nechapu cotodilo
That's piezoelectric abuse. Sadist.
where can i have this
I'm not sure what you mean by 'this'?
Beatbox at 1k volt
