How to make a Plasma Speaker

[@yiyou6529]

MOSFET goes by gate, drain and source instead of base, collector and emitter.

[@AboubakrA]

and no current flows from gate to source (no DC current anyways)

[@ryerickson837]

Yi You ah, you beat me to it

[@KeystoneScience]

+Ry Erickson haha yeah xD

[@elektroqtus]

Yi You correct

[@theblinkstykrab3106]

Yi You incorrect

[@leemd5049]

The Mos Eisley Cantina theme was icing on the cake, for me. Epic piece.

[@timothyreheht6485]

love how your videos rely on each other !

[@Elric509]

It's a clever way to induce binge-watching, i must say i approve

[@timothyreheht6485]

it's...it's for science ... :-D

[@inthisdayandage857]

Didn't know about plasma speakers, or corona discharge, until I saw it mentioned in the Martin Logan manual for my electrostatic speakers and they had a piece about speaker history. Excited to explore other creations on your channel!

[@progamer00006]

Would be cool to see actual speakers with plasma tweeters on the market XD

[@qaaris4280]

Think about the fact that dumbasses would try to put their finger in it. Yes, it's cool, but we have too many idiots on this planet.

[@progamer00006]

Mortis XD Well, the same reason i dont like the Gun law in amerika, but well.. :P

[@qaaris4280]

Good point.

[@christopholies5617]

Natural selection?

[@Jimmeh_B]

I reckon we should start removing all the warning labels.... let Darwin sort it out.

[@mrYEEHA2]

Cool video, but you forgot to mention that plasma causes nitrogen and air to combine into TOXIC nitrogendioxide. So this is a cool project, but not something to use daily .

[@joshuamoreno2694]

What field of science did you study to be able to make all these projects

[@trulyinfamous]

You seem like a more sciencey version of photonicinductions, but less crazy

[@KeystoneScience]

+Truly Infamous haha thanks xD

[@oweltaxz8874]

Haha my thoughts exactly

[@2exSquared]

And a less autistic version of Cody'sLab. And a less commercialised version of "King" of Random. And a less "let's-make-explosions-with-hot-knives" version of Mr Gear. And a less "let's-make-explosions-with-cold-nitrogen" version of Backyard Scientist and too many others. And a less "let's-make-explosions-with-high-pressure" version of the Hydraulic Press channel. And a less "let's-make-explosions-with-low-pressure" version of a few channels who just started doing this. Basically, keep up the good work and don't fall into the trap of pandering to 12-year-olds by doing the generic trashy "science" videos with "cool explosions" that everyone else seems to be doing (even though that would probably make you the most shekels)...

[@2exSquared]

yeah I like him but you can't deny he's a tad awkward in front of the camera..

[@henryswan1374]

kreosan seems cool but it's actually full of lies

[@leozendo3500]

try solder better. And, that is a BJT, not a MosFet And, dont forget to add a flyback diode. Otherwise Fantastic job

[@gstoe5560]

I'm trying to build this. Where does pin 3 of the 555 go? And which are the positive and negative you are connecting to the mosfet in the schematic. Thanks so much!

[@michaeljones2926]

this might sound lime a dumb question, but will it shock you if the one wire is in the magnet? i dont know if it will find the fastest wat to ground, but i just wondered if it was safe to touch when your playin music like in the last clip.

[@ballisticviking0292]

how did you solder up the headphone jack? in the diagram it is unclear if you soldered the tip or the ring to it

[@martinsoendergaard-jensen9602]

That is badass. I didn't even know that was possible!

[@timbelson9522]

Could the frequency generator circuit be added to a zvs driven flyback and if so how would i wire it up? At psu input of the zvs board?

[@nitul2034]

Hey how much current does it draws...??? I mean can i run it on a 12v 1.5Amp adapter....?

[@andrewbrooks7142]

Some other videos have shown arcs that appear to have a much wider range of frequencies... how do you adjust for that?

[@power45118]

Do the arc will rotate inside the magnet if we don't play the music?

[@Ryan-lu9km]

I wonder if those arcs could transmit radio waves and if the music could be heard on an AM radio, provided an antenna and a spark-gap ?

[@iamiupa]

You can really feel the basses in it! LOL

[@yomamafatoshi]

base, collector, and emitter in a mosfet?

[@monketron]

whats the song that plays out of the purple hole?

[@nightrous3026]

Think you could use a fiber optic cable for the audio input? I want to use this to power a tesla coil. I lack badly on the component side though.

[@maniac1213]

is that arc safe to look at

[@puncherbear3561]

Can you do it without the mosfets and fly back

[@SYDSNPZ]

can you wirelessly transmit an image with this? on a bigger scale ofc.

[@thomaschristensen4281]

How many amp do it draw with the 16 Volt ?

[@TheGoodS8n]

could you add a capacitor to eliminate that voltage spike?

[@runekruger6230]

What's the name of your flyback transformer or the specifics of it?

[@islandonlinenews]

At the end of your Intro there is a device with a spark travelling up a V shape. What is that called? Thanks.

[@KeystoneScience]

Jacobs ladder, and no prob

[@islandonlinenews]

I was looking for that for a year, I didn't know the name thus could not find an image or video!

[@alexlogue8762]

I'm doing this for a 4-h protect what could I use to power it

[@DouglasLabatpaleye]

would this not prove the em drive? sound is vibration and the requies force the arc is like the cone, pushing sound out. very cool.

[@ForwardBias]

No....?

[@martinda7446]

There was one commercial plasma speaker. The Fane Ionofane which was a ball about 20cm in diameter along with a tall spindly integral stand. They were advertised as tweeters only but worked up from about 1k - Production halted due to concerns over ozone production in 1976 or so..this is from memory only.

[@ИсидорПавлович]

Dear friend, thank you for the video. Sorry for my English - I did not understand everything, the speech is very fast for me, could you explain : the 3 pin of NE555 is connected with base of the transistor ? Where it is possible to see the whole circuit ?

[@stephenluczynski8045]

finally got mine working perfectly had to switch the 1k resistor to15k, the 20nf cap to a 10nf on the audio, and the 10nf cap to a 10 pf.

[@KeystoneScience]

+Stephen Luczynski huh, well I am glad to hear that you got it working !! :D

[@stephenluczynski8045]

Keystone Science. im baffled though. i plug my components into an online 555 calculator and according to the 555 calculators on the internet my driver is making between 9 and 10 MEGA hertz and that doesnt make any sense considering the 555 can only do up to 2mhz and a flyback transformer straight from a tv operate (to my knowledge) nooooo where near that frequency. so even though its working... i dont know why lol. ne555p timer, 15kr betwen pin 7 and + , 500kpot between pins 7 & 6, 10pf capacitor between pin 2 and ground, pin 5 to audio amp +out, amp -out to ground via 10nf capacitor maybe you could build what i did and check on the scope?? :]

[@KeystoneScience]

+Stephen Luczynski yeah, sure! I'll take I look at it!

[@ELbabotas1]

So... How did it go?

[@Ghost572]

Where do you get these ideas from? I'm using a few websites for projects or is it just you've done so many projects you can come up with these ideas.

[@theminimazerable]

Is it possible to use a boost converter (such as the one used in the $5 taser video) instead of a flyback transformer? I'd assume the answer is yes, as it creates an arc, but there may be a limitation I'm not aware of.

[@KeystoneScience]

+TheMinimazer yeah, it should work. Although probably keep the voltage around 6v , and it won't sound quite as fluid, but it should still be distinctive audio! :D

[@theminimazerable]

Thanks for the quick reply! I was hoping to make a small battery-powered variant (2 18650s in series with regulator). Lower audio quality shouldn't be an issue, as it's just for fun.

[@KeystoneScience]

+TheMinimazer ahh ok cool! If you want , you could probably even just use 1 18650 battery and it should still work tbh

[@theminimazerable]

Very true, but I have 2 batteries that I'd rather use equally to reduce issues with one having more use than the other. I may just put them in parallel to extend the battery life of the device.

[@samn6201]

How did you remove the squeaky noise did you lower the capacitance

[@KeystoneScience]

+sam n yep! And tuned the resistor to get it at a frequency I can't hear

[@yume-y3m]

the spinning arc is actually similar to how a magnetron from a microwave works

[@gmakwa1]

Been having a lot of power outages lately and I was wondering is there some way I can use a big 12 volt deep cycle car/boat battery and some device to give me the 5 volts it wants to power my PSP 3000 FOR DAYS instead of a couple hours?

[@ma.lornatoledo3766]

Sir where is the pin 3 connected??? Your projects are really interesting... Please reply

[@sethcallahan6486]

Wondering about the plasma burning off air, there being nitrogen and oxygen and how ionizing the would help or hurt the o zone.

[@KeystoneScience]

+seth callahan as the air is ionizing it is producing ozone, so I guess it's helping the ozone, but at this close to the ground, ozone is not really good for the Environment... But don't worry, it's a very small amount produced by this :D

[@sethcallahan6486]

Thank you kindly.

[@lopezstallon8449]

can I use irfp260?

[@stephenluczynski8045]

so i got a flyback today and i got it working but very week spark which primary pin on the fbt is the positive normally?

[@KeystoneScience]

+Stephen Luczynski I'm not sure, it varies depending on a lot of things, what is your input power ?

[@liambewick7523]

How can I amplify electricity?

[@rodrimunoz9110]

It would be nice if you could manage to make a OZONIZER :). It could help some ill people on a buck and also it involves HV, just as you like.

[@KeystoneScience]

Sure thing! I'll make a design!

[@Teth47]

Good excuse to make a capacitive voltage multiplier.

[@ryley6077]

I have like a 20 year old one of those. Its works really good for all sorts of ailments.

[@avocado2084]

iooi dude, those were capacitors, not resistors

[@carolynmmitchell2240]

Rodri Muñoz I thought ozone was bad for you

[@lopezstallon8449]

can i also use this as a high voltage power supply?

[@lopezstallon8449]

Don't want to waste another flyback for a different projects...hitting two birds with the same stone I wanted

[@rileydowns6005]

ok so prabably pretty stupid question but where does the wire from pin 3 on the first schematic go exactly? ive been studying the schematic a lot and cant figure it out if you have an answer that would be great

[@KeystoneScience]

+Riley downs yeah, pin 3 is the output pin, so basically it gives off the signal created by the 555 timer, the other end of the signal is the negative ( pin 1 )

[@rileydowns6005]

ok thanks

[@SciHeartJourney]

Base, Collector, Emitter is for a "transistor", not a MOSFET. A MOSFET has a Gate, Drain and Source.

[@draftartmart8069]

Richard Vasquez MOSFET is a transistor just that it uses voltage to turn its gate on rather than current

[@horus2779]

Can you try using a Neodymium magnet

[@aMapleSyrupCaN7]

I think I'm going to make this just for the circular arc!

[@KeystoneScience]

Haha xD you don't need it to be musical for the circular arc, any high voltage plasma in a magnetic field like the ring magnet will do this :D

[@eeyoare]

i started watching your videos recently and love them but a small note; you should link the previous videos you recommend as background in the info of your videos

[@ms2649]

4:42 i hear a really high pitched noise

[@petermuller7687]

Nah not really cause I can hear it too

[@donnawander7710]

Michael Snip its from either the music or the transformer.

[@bocmanisbertrups9292]

AnnGell his ears are in perfect condition if he can hear high frequency noises

[@dalenassar9152]

Thanks for the great video!! ...one thing: The resistive "isolation" method is NOT the way to go, especially when you can power the function generator with a simple battery! It's just risking too much.

[@balanbogdan9160]

You can add an reverse diode to the primary to prevent Kickback!

[@cyberbruiser2515]

very informative,good work man

[@paulneilson6117]

Excellent presentation. True that MosFets are gate source drain and they are easier to use than regular silicon transistors. Also a couple of seconds more on the schematics to make it easier to pause the video. Perhaps a short video on mosfet theory would be good. How did you identify the pins for the flyback primary coil?

[@combycat]

Resistance is how you find the primary.

[@Appl314159]

Can anyone find his old video where he shows a step by step tutorial on how he made the frequency generator? For some reason I cant find it

[@guyscamp4512]

pretty cool man keep doing what you're doing!

[@KeystoneScience]

+guy scamp thank you!

[@imagine_laabs]

The transistors have about 700-900 Vds

[@Jhantow]

nice job, you should have more views.

[@stephenluczynski8045]

ive been experimenting with different adjustments even cap values all night. cant het that arc noise clean or any hint of music coming out. having the same damn problems as years ago but atleast then i could get a hint of audio through. i know 555s are very simple but i havent had much luck. any ideas?

[@KeystoneScience]

+Stephen Luczynski hmmm, could you send me a picture of you circuit ? ( my email is [e-mail] )

[@stephenluczynski8045]

Keystone Science sure thing ill send one right now

[@stephenluczynski8045]

Keystone Science i appreciate your imput btw :)

[@ShreeAkshaya-fp1vg]

Link for frequency generator

[@CollieBoyZ]

What is the best way to power the FlyBack Transformer and at what voltage/amp?

[@KeystoneScience]

+Conner Collie the higher you can get it the better, the main only limiter hear realistically is the mosfets getting too hot

[@KeystoneScience]

+Conner Collie * I meant here not hear :P

[@CollieBoyZ]

Thanks for the quick reply. Do you know of any cheap equipment that could power it easily?

[@KeystoneScience]

+Conner best thing to use is a variable power supply, although they can be around 50$ , the next think I would use that is cheaper is probably a old laptop charger power supply, then can supply a few amps at like 18 volts or something like that, and that should work ( although it would be better wi a higher voltage )

[@CollieBoyZ]

Which amount matters most? Amps or Volts

[@jellyfish1433]

loved the star wars part

[@rbmwiv]

You can use diodes on the line in as protection for your music playing device. That should keep any feedback from frying it.

[@TheBrannagan]

So cool! I certainly hope your parents hearts are bursting with pride for having such an intelligent and great son. It's awesome to see a young man making good use of his talents. I'd bet you are going to go far in life. Thank you for all of these great videos, I've found a few that I'm going to try myself. Is "Keystone Science" representative of being from PA? Just wondering as I'm originally from Pittsburgh.

[@KeystoneScience]

+Brannagan O'Brannagan that's very kind of you! Thank you! And no, ( even though PA is the keystone state ) it's more of a reference with my families business ( it's not called keystone science , nor does it have anything to do with science but keystone is used in the name ) also, it represents my last name, and finally I guess I just like it because it symbolizes a bedrock foundation of science. But yeah, that's why I guess... Thanks again! :D

[@kennethkeys2248]

Keystone Science Heyyyy my last name has to do with keys too! :D

[@riaanferreira2130]

I really love your videos man! Keep up the good work.

[@riaanferreira2130]

Just a correction: You really shouldn't use the term Mosfet, when what you are describing is actually a BJT transistor.

[@StaticYonder]

Oh my Gosh the Cantina band Music 😍 😍 😍 😍 😍

[@andrewpike2924]

Yes I did learn something new. You have fond s new type of MOSFET.

[@PulseStarz]

pls show how to make an air diffuser

[@pfabiszewski]

Am I wrong or MOSFET has gate drain and source insted of base etc?

[@KeystoneScience]

+Paweł Fabiszewski your right! Technically what I use is actually a horizontal deflection transistor , but it's more commonly just called a mosfet, and so just for the sake of teaching people basics I decided to use base collector and emmiter

[@pfabiszewski]

Keystone Science ok. I would be a little confused if you make such a simple mistake due too your great chanel and knowledge. now I see the point. thanks!

[@KeystoneScience]

+Paweł Fabiszewski haha, no problem! XD

[@KeystoneScience]

+Victor Titov yah, but technically it's not a mosfet it's a horizontal deflection transistor xD

[@Jimmeh_B]

actually, you are right, the horizontal deflection transistor is a BJT or bipolar junction transistor, not a MOSFET aka Metal-Oxide-Semiconductor Field-Effect Transistor.... two completely different beasts. His knowledge is limited to other peoples designs on google and often makes mistakes in his terminology, but the young fella is learning and teaching himself in his spare time, which is more than most of the kids these days so hats off to him.

[@yanivbk]

Great stuff man, how about building a kind of plasma audio visualizer using a plasma ball or plasma arc¿

[@NateBlanous]

Wow man that's is awesome!! I will defiantly be building this!

[@KeystoneScience]

Thanks man!

[@yourdad9168]

Such fidelity

[@thecornishmaker5285]

Now you need to make a bassy thing

[@dangerouspie0319]

This is fucking cool.

[@mmmk1414]

correct me if I'm wrong but isn't a MOSFET have Gate , Drain, Source instead of C,B,E ?? and MOSFET doesn't use in amplification ??

[@Hobartez]

These are really great videos

[@KeystoneScience]

+Matthew Barnes thank you :D

[@blockerman3d266]

I know I'm late on this. Just found your channel. Awesome stuff. Subscribed. Maybe a reflective bell as a speaker as used on a phonograph. Depending on the turns and such, it could be an interesting show in addition to sound amplification.

[@stephenluczynski8045]

you never showed how to hook an audio port to the freq gen in the video about it

[@KeystoneScience]

+Stephen Luczynski yeah, but it's shown in the schematic in this video, basically one end is connected to the negotiate, and the other end is connected to pin 5

[@emanueleperinciolo9795]

Wait how can a dc arc can sing? I mean a music signal is an ac signal,not a dc

[@gmakwa1]

Great video.

[@Felisargyle]

So can't u put this across the spark gap of a tesla coil and make the coil play music ??

[@Hosigie]

Christian Wang Tesla coil is basically the same thing. But with higher voltages and is much more expensive to make. Works a bit differently too, it uses PWM to modulate the way the coil oscillates with its own resonant frequency (that's a couple of hundred kHz which we can't hear). You'd need a different circuit but you might be able to use the frequency generator out of this.

[@nguyentu3706]

I use irfp260 and i can not see plasma :( i use wrong mosfet ??? Someone help me
