If you want to be a smart person - go to Brilliant. If you want to see my new website, and learn more about why i'm obsessed with plasma, go here - www.PlasmaChannel.net. Also, sorry about that high pitch noise in the beginning! It was mostly an artifact of the camera being too close.
Flyback can't be AC Jay, you keep making the mistake. Flyback is the name for the "topology", pulsed DC to pulsed DC... but it's not the only way to get HV DC, you already played with an ignition coil, and that doesn't even have a diode on the output, yet gives DC (if driven right) 1EabqJJnWhc
btw it would make more sense (be more efficient) to modulate a Mazilli ZVS when you're using output AC. Look what CoolDudeClem tried, but there are other more successful attempts, just can't recall channel names.
@@sFeral As long as the spark output by an ignition coil dissipates all energy in the first cycle, it will be DC. In reality, most all ignition coils i've used have a ring on their output. As for flybacks - they are AC by nature. The addition of diodes is what makes them DC, or, an offset secondary balance will also do similar. Any secondary coil that is mid point balanced will output one terminal negative voltage, the other terminal positive. I tested my custom flyback to have an AC output.
@@PlasmaChannel I love it when random commenters try to get smart with the pros but they're actually wrong. sFeral, ya made me laugh. Do your damn research before ya make corrections.
where can i buy these parts?I want to buy too I'm trying to do something
Love your videos! I did a similar circuit with my Tesla coil but my method of control was PWM and that seemed to provide a very clear and loud sound. The spark frequency was however much higher at around 2 MHz.
Another wonderful video, Jay.
Ionophones are one of the first HV projects I ever messed around with, and are always an interesting conversation piece, even to those who are familiar with this kind of work.
I love that giant table saw! Makes for some very clean builds.
damn man, who is making your videos? there is no way an engineer can have such video editing skills and sense for good quality video production... best wishes, keep them coming...
I appreciate that. The trick is...i'm not an engineer. I'm a maker :P
@@PlasmaChannel 😂👍
You might be surprised...
@@PlasmaChannel what do you do for a day job?
That flyback design looks gorgeous, the 1st one.
I also used one of those XY-P15W mini amplifiers for a big slayer exciter project. And it worked flawlessly!
This thing can power small to medium size subwoofers very well with minimal distortion under 30Hz. It's a very neat amplifier for it's size, that's one thing for sure.
Excellent video Jay, I loved the design aspect of this project. Unique as always!
Plasma is the future !! THANK YOU SO MUCH FOR ALL YOUR WORK.
Dude I love this channel. It is everything, exactly what I want to see!
Hey Jay! Love your videos and I love seeing your build process. Your clear plastic parts are so eye catching to me, I love the blue piece you made for this project so much. Would you be willing to do a Video going over most all of your tools& processes? Im interested in hearing all the tips you have to offer
Man ! The intro is just awesome as hell ! You blew my mind 🙂 🔥 That sound gives me a sci fi vibe ... Thanks 👍
Love it, amazing as always!!! Keep up the great job
Thank you so much
That is another beautiful piece of functional art, Jay 😊❤
Hey Grandad, thanks. That's my style. More of an artist than an engineer!
Nice clean build as always! I love your “giant” table saw 😭 That electronics store looks amazing! Is it in Washington?
Hey Nigel!! Thank you sir. Yeah, that table saw is the thing of dreams.
Vetco electronics is the only store near Seattle.
In Tucson we have Elliotts Electronics
@@PlasmaChannel Vetco has helped me out so many times!
I once seen a splama speaker made with two half globes curved surface to curved surface with a space between them and a high voltage arked between them. I imagine they helped the sound curve the soind radiate it in all direction while concurrently providing capacitance for a hotter louder arc.
It's amazing, the sound is very good
Loving how the channel pushes you further ;-)
Awesome content that I like to share with my kids. Thank you !
Thanks Dave, it certainly pushes me further. Every video...I learn something
That improvement in audio quality and design is amazing. Also as you said in another comment sometimes there is distortion when recording so I can see it being nearly silent in operation.
Hey Mad Scientist! Good seeing you here. Yeah, after thinking about it, my audio equipment has a good 4-6" loop of COILED wire going from the audio receiver, to the camera. The audio equipment clips ontop my camera. The camera was only......5 inches from the arc during many of those shots. So I think the transformer pulses were artificially inducing a voltage in the audio equipment. Bummer - the arcs are hot and silent in person! At the right frequency.
@@PlasmaChannel that's another good point that I didn't even consider. EMI on the pickup. I wonder if having it shielded would help. I'm thinking like that perforated or mesh metal like on the older studio mic's.
Thank you for your story arc on creating musical arcs.
This channel has everything I've been searching to find!!! Like WOW!!
Thank you. Xo
Thanks Kimberly! If you have questions about any of my projects, don’t hesitate to reach out.
bro this is epic, keep it up you are one of my favorite innovators, please create a whole plasma speaker, that arcs epic on sounds, that would be next level, and this is an interesting way of distributing sound without using magnets and membranes to shake the air.
Thank you, I appreciate your support
Can't wait. This is so tight👍
This comment is to show support for your channel... Cool project, I have to say, I'm a big fan of 555 timers... I use them all the time, but this is one of the best ideas ever for one of those... kudos!
What a quality work man....!! Love from India buddy
Very nice idea to make sound by arc! Some details interested me: switch makes meandres which transform to saw-like signals after current-field-current transformation. It will be interesting to see that. Also interesting to see some illustration of sound specter transformation.
Nice clean build
That was really cool. I'd love some more footage of the finished product in action!!
I can do a follow up video, for sure.
@@PlasmaChannel cool! 🙂
@@PlasmaChannel You sir are a badass!
Keep it up!
Also, I’m in Snohomish County. We should grab some beers and have a lively conversation regarding electricity.
I hear the frustration with AC flybacks. What I didn't know was the little ones for CO2 lasers were AC. Thanks for the info.
Great project as usual. From a plasma nerd down under
You're a geek 😎😎
I love the content you are doing ✅
that was amazing
Okay you finally convinced me to use Brilliant.
your title and thumb, never do justice to what i find in the vid, i mean, i only click cuz boreed, now, im glad, i mean, is like a vault of information and music to my brain. i feel dumb for not getting here before. i didnt imagine music from plasma, you know, literaly, but blew my mind
Hey, I want you to know that I really appreciate your comment. MAKING the thumbnail, often, can take hours. To try and figure out the best way to show the world your video, with a single frame, is nearly impossible.
But the fact that you think my thumbnails aren’t as good as my video is actually a huge compliment. Means you think my videos have good value.
Thank you
Now this is freaking cool! Loved it!
Thank you!
@@PlasmaChannel your welcome! I always love checking in every so often to see what cool new thing you come up with. Every so often I build things myself it’s always fun. But heck, it’s not even close to what you build. Maybe one day I’ll figure out how incorporate some of the things you invent and make my invention just a bit cooler 👍 always love your content! Keep it up!
Excellent video Jay, that's quite the beast! Have you considered using it to make a musical Jacobs Ladder?
And also...your mini table saw is easily one of the coolest tools I've ever seen.
Haha right?! My father actually gifted me that for Christmas. It's the best. Musical jacobs ladder sounds amazing.
@@PlasmaChannel You could play Stairway to Heaven on a loop and put it in a time-out area or use it to remove house guests that have gotten that fishy smell. I love the song but after a few hundred loops pain sets in which explains most chemical abuse in '70's nightclubs.
@@PlasmaChannel Yeah! The Jacob's ladder is one of the projects of Mehdi in ElectroBoom! You can get a good idea from it! Very high voltage with powerful arcs!!😅 You are Great man😊
This was the first video I've seen of yours, and I dont think that any combination of words has ever caught my attention faster than "plasma river table." I subbed before I even saw the clip, lol.
Also, the sound of the electrical arc was so strangely soothing. Maybe it's because it reminds me of the sound of my parents' old CRT or the plasma globe I had as a kid, but I've always loved that sound.
Anyways, great video. Thanks for the great content!
To make it even more awesome add a ring magnet as the hv ground and place the other hv lead in the midddle of the hole, and now you have a plasma vortex speaker, as the output gets spun by the magnetic field. this results in a disk of plasma in a vortex, and volume is increased.
I thought about that after I posted it this morning. I thought, "Why not a vortex speaker!?" So, i'm going to try it.
Jay, sometime in September 2005 I designed a Halloween themed circuit, from some online research that I did on arcs I discovered that using brass balls generates more noise than sharp points, your ionic speaker build could benefit from this knowledge
I usually use a variant of an astable multivibrator to power my flybacks. It allows me to change the time period for both the on and off states. I started using multivibrators because BJTs can tolerate up to 30 volts, where my 555s burned up at 15 (Under 12 without protection). I also had trouble driving a stable frequency above 21 KHz with the 555. I'm currently working with one that goes from 6 to 60 KHz. I made a mock up of the inside of a microwave magnetron, except without the resonant cavities or emitter. The arc spun around at probably 30 to 40 Hz, so no danger. An idea for a video, but I must warn you, it took a lot of current to overcome the electrostatic confinement from one anode fin and allow it to jump to the next in rotation. Enough to melt the cathode. (I'm guessing about 22 milliamps at 12KV, about 250 watts.) Oh, I also needed an RF filter between my driver and the power rail to compensate for the voltage drops when dumping around 25 amps at 20% duty cycle.
Another great vid 👍 good job
Very nice! For HV output terminals that can endure the heat of the musical arc, may be try a copper-tungsten (CuW) alloy rod segments. I hear it's easier to cut than pure tungsten.
Or just get tungsten TIG welding electrodes, which are pre-made to an appropriate length.
Every video of yours is absolute gem. Looking forward for more interesting videos. Man made whole channel based on plasma and think we wouldn't even notice.
Thank you Aryan, thats really nice of you. Glad you enjoy my videos.
Nice build as usual Jay, a great way to ensure that there will be no arcing over is to encase the windings in epoxy. Maybe you could use the remaining epoxy from your table
Thank you. Yeah, I mentioned in the video that I was thinking of encasing the windings in resin. I found a far better solution. To dunk the entire secondary in Super Corona Dope, then place in a vacuum chamber. It gets the Corona Dope in between the windings, and does total wonders.
awesome ! love it
Excellent video. I can definitely see you getting 1 million subs soon 👏
Awesome! The good old 555, works like a charm.
Thanks Chris. Man, the high pitch sounds so much worse on camera than in person. Honestly, it's almost silent in person.
@@PlasmaChannel might be audio compression from your video editing.
I haven't used one in a while since I made a power inverter!
Wow you are next level.
Could this circuit have an audio jack instead of bluetooth? Or would the arc put noise into the jack disrupting the signals? Also how much current does this draw?
Sweet project. Really impressed by your build quality. You would probably laugh at the monstrosity I built years ago to do essentially the same thing with a 2N3055HV transistor instead of a MOSFET with huge heat sinks and fan cooling for the transistor and the power resistors. 1/4" audio jack for plasma speaker operation. Done "wrong" but works perfectly with a larger footprint. :)
That whisper to your 3D printer is the ice on the cake for this video 🤣🤣🤣..love it ....nice work as always
Thanks Abbey, haha, sometimes you need to say tender things in order to get stuff done.
I would love to see an entire video dedicated to this arc playing music.
Tho, you might not be able to monetize that one.
But, for sure, this is an amazing product, (no moving parts) especially if it can play BASS frequencies.
hi jay! this build was really impressive! You should try powering a plasma globe with it!
Oh that's a great idea! Dont know why I didn't try that....
Feeling fly⚡️
Very good its a good hivoltage musical device.
Awesome build.
Thanks!
Thank you for this. Ive been struggling with this circuit for awhile and many of the other videos on plasma speakers aren't very clear or easy to follow. Quick question, can the neon bulb be replaced with a zener or ultra-fast recovery diode? Thanks again!
Keep up the good work
Hey Jay, I hope you're doing well! I've been following your content and I'm enthralled by your knowledge and passion for plasma physics. I was wondering if you have any plans to build your own plasma toroid like BackMacSci and others have made? I'd love to see your unique take on the device, its construction, and operation. I'm sure your followers would be just as interested as I am.
That video honestly is planned. I've been in talks with BackMacSci - met him at a conference in November accidentally.
@@PlasmaChannel That's awesome to hear! I remember seeing a photo of you two from that. Can't wait to see your take on the plasma toroid!
Wow. This is so nice Jay. I'm going to have a look and see if I can build one too.
~Kian
Hi Jay! Great video as usual. I'm surprised the 555 can drive a p260. I'm pretty sure if you add buffer transistors to the output of the 555, you'll get a better output and put less strain on the 555 because they'll carry the current. The mosfet will run better too.
I found very good results using a totem pole driving stage. It worked fine without it, but the 555 kinda struggled to switch the FET hard enough, so I wasnt getting a nice crisp square output. made the fet run hot and limited the amount of current it could put out. a totem pole really improved the output drive waveform under load, ran the FET cooler, and my arcs doubled in thickness and meanness. the only other mod to this unit that made a bigger difference was going from 24v to 100v, which was a MASSIVE redesign for many reasons. you should be able to shoe-horn a few extra transistors on any design without much effort.
@arjovenzia exactly. And if you check the design on the 555, you'll see inside of the output on pin 3 is actually a little mini totempole. So by adding an extra stage, it's like steroids for your pwm lol.
I wonder if only making pulses when the audio makes pulses would sound any better than adding a square wave to the music.
It likely would increase audio quality. My driver circuit was really basic - some people get crazy complex with their designs....and you get what you pay for. Rather...you get what you design for. I was most interested in voltage output, with music as a secondary. But some plasma tweeters are incredibly clear.
I’d have to experiment further by mounting a tack or something similar to the centre of a tin foil pie plate and and seeing how much more tone and acoustics you maybe able to get.
Pretty cool!
except for the mistake he keeps making of calling everything a flyback lol
Let me flyback to that comment real fast. [lolz] Yeah, I do use that term quite liberally. Flyback and high voltage, high frequency ferrite core transformer for me go hand in hand. Even though they aren't all flybacks! Fair point, good sir.
Any old radio in the neighborhood probably replicated the sounds too, from the EM pulses.
You can listen to an AM radio transmission just by gently holding a leaf on a branch against the high power antenna.
Yeah lots of interference with high voltage arks sometimes they can fry your circuits if powerful enough!
@@patrickday4206 These arcs can make TL lights closeby flicker.
@@paulmichaelfreedman8334 lol
Hello friend, it looks like your flyback is warming up! The 220n capacitor on the primary winding will create resonance and increase efficiency. Is there a link to the 3d model? I'd like to wind one too. Thank you in advance!
That flyback was more than warming up. It was melting lol
@@PlasmaChannel Ha ha! Good sense of humor) On my channel, the latest video. There the flyback works for 10 minutes, without radiators and with zero heating. The power supply is 1 bank of 18650, but you can also set it to 12 volts. By the way, can you give a link to a 3d model of the frame? I want to repeat.
You can get louder volumes and more power using an IRFP450n mosfet. It will require more input power and a bigger heat sink.
Thanks for the suggestion. I'll try that!
The begining sound made my skim tickle...oddly satisfying
I really need to get ac flybacks sometime for a voltage multiplier
Everytime you upload a new video, I feel satisfied. You are only the one who rules over the lightning and thunder. I think you are the god of lightning and thunder. ⚡⚡🤩🤩
Wow, that's an honor! Lightning and thunder are friends.
Awesome ❤️
loved it
omg, what is this table saw?? It is so tiny, yet so perfect! I've cut multiple acrylic panels " by hand" and this table saw would come in handy !
i love your giant table saw.
It’s the perfect table saw…. For when size matters
Buen dia, una consulta donde puedo comprar el nucleo de ferrita y cuales son las medidas, para fabricar el transformador
Imagine 10 in a row, tune each one to be triggered by seperate frequency ranges (overlapping slightly to avoid cutout), would be a unique little light show for each song if you could tweak it right!
Idk that much about electricity, but I really enjoy watching your videos
I appreciate that!
Highvoltageshop a german based supplier sells AC flybacks. I used one with 36v with a 300Wh battery and man the arc was over 5 cm long!
yeey you added capacitor!
A couple serious(?) questions:
1. To what is is the hand-held conductor connected? That’s the wire you’re holding making the arc.
2. So when we’re hearing music while you’re playing music wirelessly the sound is actually coming from the plasma arc?
Love all your RUclipss. As you can tell from my questions I don’t understand anything you do, but the colors and the crackling sound the plasma makes is really beautiful.
Honored you enjoyed! Yeah, the thing i'm holding is just the other side of the high voltage output from the transformers. I have a wire attached to the output, then i'm holding that wire (safely), and bringing the wire towards the other high voltage wire.
@@PlasmaChannel thank you for that explanation. I see now what you mean on rewatching your RUclips.
I built a version of this a few days ago except I used a zvs driver, and it doesn't have Bluetooth. Only a 3.5 mm audio jack. It can handle about 250 to 300 watts and makes an arc about 3 or 4 inches long.
Wow that's crazy. You should upload a video, and provide the link here.
@Plasma Channel ruclips.net/video/hiQFqK3zi5Y/видео.html here's a video, sorry if it's really low resolution-im not sure how to fix it if it is.
Imagine if you made the plasma table dim and brighten to the beats of music you play with a similar circuit :)
I would love to hear a musical symphony played by lightnings, like those which appear at thunderstorm. Make a gigantic lightning into an arc. A 2 kilometre-long arc reaching clouds. The bass would be ground-breaking. And then a voice speaks from the sky!!!
I suggest the plasma filament needs to be in a clear glass vacuum. Plasma does not need oxygen. Plasma is a state of matter that consists of ions, electrons and neutral particles. It can exist in the absence of oxygen and can also exist in a vacuum. That said, in suggesting that, I'm not sure how well the speaker part would function, if at all. However the filament might last longer.
You know you have good headphones when that arc at the start pierces your brain.
Wow you make such nice videos
Very nice!
But looking at your circuit diagram, I think you should add a LC filter or at least a decupling capacitor before the transformer as well. As it is now, almost all current will be drawn as pulses at the switching frequency, directly from the power supply. That can mess with the regulation circuits of your power supply - which can explain the problems at 5:38. It seems very unlikely to have something to do with the audio signal - the control signal input of a 555 is quite high impedance and you would fry your audio player long before any significant part of the current can take that path.
The resistors probably helped by just lowered the control signal (audio signal) amplitude and thus keep the frequency and duty cycle variations lower (a more erratic frequency and duty cycle usually causes interference problems to get worse - but the main problem can still be the pulsating input current).
Thanks for the feedback! You know, I tried (off camera) adding several values of air-cored inductors on the positive path to the transformer. I tried 1uH, 5uH, and 10uH, all with no change what so ever in performance. Though....the 10uH did seem to drop overall current draw (which makes sense). So you think I should try a Decup cap? I appreciate your feedback, greatly.
@@PlasmaChannel Yes, but it will do more to add a parallell capacitor from transformer input to ground. Which can supply the pulses needed.
Every time the MOSFET turns on, it will draw current, which stops once it turns off, while most of the stored energy in the transformer is transferred to the high voltage output (a flyback is like a combination of the inductor in a boost converter and a transformer). Adding an inductor in series before the transformer will just waste energy (since the energy stored in that inductor can not get transferred to the high voltage side - it has to get dissipated in the MOSFET or snubber circuit). The reason the total current dropped with the biggest inductor is probably just because the input pulses got choked - which doesn't help much and you may risk to blow your MOSFET due to the voltage spike when it turns off.
But a capacitor in parallell, can supply the current in pulses, without the need to travel all the way from the power source (possibly making your cables act like antennas and cause RFI).
Then adding an inductor between that capacitor and the power supply, will further help filter out any remaining ripple and get a pretty much continuous DC to flow from the power supply. But it's the capacitor that do the main work.
Awesome video, one of my favorite HV projects :) What is the brand/model of that table saw? always wanted one, but all of the seemed too big or too flimsy, until now! :)
It was (go figure) some chinese company from Amazon. Look it up, there's a few!
@@PlasmaChannel Alright, thanks! Found some on Aliexpress. For anyone interested, Ali key words are: "Multifunction Mini Table Saw" One from "NovelLife Store" looks most simmilar.
Could a bifilar coil benefit this circuit anywhere?
Was the quality better in real life? I would assume that the emitted square waves could cause interference with the microphone circuit and not truly capture the sound quality to its fullest.
Thanks for your contributions. It is great to see your continual optimization.
Plasma king 🙏🎉
This was great! Thanks for answering the call :) it was kinda cool seeing my comment up there on screen too 😎
Haha well thanks for commenting!
If there was a way to reduce that plasma noise like reducing the static of a turntable by cleaning the records, I thin it'd be much clearer sound, although kind of flat sounding.
If I remember correctly if you need the output to be cleaned then the input you run a 555 op amp into a 555 op amp as a negative feedback loop. Though for just power not sure if that's needed.
Reduce the inlet spacing. Along with that, increase voltage on subsequent stages. This mimics multiple stage compressors on and a jet engine. thats probably a lot more work electrically at least.
I have a suggestion on how to increase the thrust of a jet engine, my idea is based on the principle of a fanless fan, The thrust of a jet engine is directly dependent on 2 factors, the amount of air it blows out, and the speed at which the gas flow blows out. I want to increase the amount of air, it is known that fanless fans blow 15 times more air than the turbine itself pumps For this, it is necessary to remove the outer housings of the jet engine, and create new housings, according to the principle of a bladeless fan, part of the jet stream must be used to build up pressure inside the new housing, which will throw in a jet air stream at the beginning of the jet engine compressor, in this way it is possible to increase the amount of air in engine, you're supposed to work with a lathe for a bit, and figure out how to force some of the jet into the hulls, but then you get new types of Jet Engines.
Nice job, thanks for sharing. Now, for the unsolicited advice: Without forced air cooling, you should orient the heatsink to take advantage of convective air flow, or at least avoid obstructing the fins. Maybe drill some holes in the acrylic underneath the fins. Depending on the amount of heat, just having a large surface area can be enough, but it's bad form to block the fins.
No, it’s true advice. I just care about appearance and form more then function sometimes. It was designed to be a flat surface. So, the heat sink does get very hot after a few minutes… which is good enough for me.
@@PlasmaChannel Handsome, smart, *and* gracious :)
that 555 circuit was good
Thank you.
Best profession: "RAGHH, I HAVE THE POWER OF IMAGINATION, HUMAN INGENUITY AND CREATION BY MY SIDE, AND ALL THE TIME IN THE WORLD - YES!!!"
but nobody will hire me for that, must be too awesome.
Great video by the way, I like the background info like the difficulty of parts sourcing - thanks and have a great day and why not week :)
Jay's moans of enjoyment when he sees plasma made my family very curious as to what im watching. Awesome project tho im willing to try it.
Omg hahaha sorry about that
Great Video
Thanks!
That huff after reading the parts list 👌
Question is there any reason one of these couldn't act as an ultrasonic transducer?
I mean if I ran it close to 50khz could I get decent audio from 15-25khz? Or would I be better off rapidly changing impedance on the other input?
If you only want one frequency (and many harmonics of it) It's actually easier than that:
The ac from the transformer is already enough to get sound produced by the arc.
Note that the arc fires twice as frequent as the drivers frequency, since ac passes zero and reaches a maximum twice per period, becuse of that you'd have to drive the transformer at 15kHz to get 30kHz
If you want to have a plasma speaker for ultrasonic waves you indeed need to set the driver to a significantly higher frequency. The theoretically lowest possible would be twice the sound's frequency due to the Nyquist-Shannon sampling theorem (the 555 chip can only change once per period, and thus has a sampling frequency equal to the drive frequency)
You may be able to drive a flyback transformer at 100kHz, but for that you will likely require a larger heat sink, changes to the circuit or a totally different circuit, as well as a well picked Mosfet
Nice video! 👍
