BackMacSci - 2023-03-07
I officially have a plasma toroid generator on my desk that can run indefinitely--no more heating issues. Engineered Labs Shop https://engineeredlabs.com/ Join the mad science blog of magic_plazma : https://t.me/magicplasma SCHEMATIC AND TUTORIAL: https://docs.google.com/document/d/1AyaO-RaTiaOmyT3-89UxPdrMHEBCCrxb1irZKsVMg_8/edit Inspired by @magic_plazma on Instagram: https://www.instagram.com/magic_plazma/ Follow me on Instagram and TikTok for more science experiences! @backmacsci In this video, I explain how a plasma toroid is ACTUALLY generated, show you the experiments I've done over the past few months, and build a new, smaller, simpler, prettier, more efficient device based on Steve Ward's circuit and test it out. It was a lot of fun and my future research into the device will be using different gases like @kcakarevska to produce different colors and cheaper designs. Imagine we make one with low-pressure air and it looks like the aurora borealis, and the whole thing costs only $100! You can all join the plasma donut club then!

Great video man! Little tip for working in the shop, do not wear gloves when operating the band saw and drill press or most power tools for that matter. If they get caught up in the machinery it will pull the rest of your hand in before you can even think to pull away or shut off the machine. A little cut to bare skin is better than losing a whole finger or worse. Stay safe my friend! Keep up the amazing content!

Thank you!
@@BackMacSci On the same note, remember to drop the foot to a quarter inch above your work piece. All the way up is unsafe and bad for the blade :)
He ain't lying. I used to work on commercial food equipment and there was one call I'll never forget. A guy was operating a large meat grinder with the lid safety bypassed and dropped his knife in the hopper. When we got there the fire department guys didn't' know how to get him out. We had to switch one of the 3 phase power legs to reverse the motor and squish out what was left of him. There was another instance upstate where a guy got his arm caught in a 80qt. mixer, it ripped his arm off and proceeded to beat him with the bloody stump. You can never be too careful, to a machine everything tastes the same.
same as above except use a tool to push the work towards blade for close cuts...
I would love to see this refined even more in the future! Cheaper gases + custom PCB = win for everyone. Also, good luck pushing towards doing youtube as a career/at least ramping up the channel! Love the videos so far.
Thanks for watching until the end! Yes, what you described (cheaper gases + PCB) is my plan.
@@BackMacSci Neon would be cool, because pink. Low pressure air, would probably work as well.
It does seem rather sensitive to how the globe is positioned however. I wonder if the circuit could account for this.
I would be up for designing the PCB and sending out Gerber files for free if anybody wants them. I'm going to build one of these
@@lukehaworth5789 What program do you use to create your Gerber files?
@@Mark_Nadams idk about him, but I use KiCAD personally. Open source and free, easy enough to use while still being powerful, I feel it's a good option
Watching the phasma jump to life has got to be one of my favorite things, I would love to see a high quality 10 minute extended looping footage with that plasma ring floating in the middle in a dark room something like one of those videos with a cracking campfire or ocean waves. Great job on the video by the way.
4K 120 plz :)
Well, I guess you could say your desk is now officially out of this world! Congrats on the plasma toroid generator, and I'm excited to see what kind of colorful creations you'll come up with using different gases. As for the metallic potassium and platinum samples, I think my video idea would be a dramatic recreation of the periodic table. Can't wait to see what you come up with next!
you want the potassium sample? i like your idea!
@@BackMacSci I would love that! and hope your new youtube career works out! its exiting to see new creators, especially in the DIY tech space. super stoaked to see what comes next
@@SpeedrunnerG55 thanks man! what's your email?
I would love to see some harmonic resonance test between the toroid ring and the acoustic input - im wondering whether it would act like fire in making some interesting dancing toroid displays :) excellent work once again man, so cool seeing how far youve come with this tech!
This is one of those things where if you saw it in a movie you'd think "wow, they've got no idea of how things really work". Incredible work! I really want one of these.
Hey Tate,
I came across your video today and I want to say, excellent work. I love the content. Keep up the hard work and continue to improve your craft. You’re quite good at breaking things down for everyone to understand, you’re humble, not afraid to show accidents, admitted mistakes and willing to trying again. Yes you can make YouTube a career!!!
Suggestions:
- Try using graphics to help explain complex concepts
- Please use personal protective equipment
- Consider refining and putting into production the Plasma Toriod (different base materials, shapes, colors, variety of glass tube shapes, sizes, different color gases) these are way cooler than a plasma lamp and would look great in a kids room to an executive’s office.
Thank you Anil, I appreciate your kindness and feedback!
i'm surprised that the glass didn't shatter when you cooled it extremely quickly after it was heated by the plasma. please be careful.
great video, i've been really enjoying following along with your experiments.
Muito bom
Ikr when he dipped it in the liquid nitrogen I was TERRIFIED
Why didn't it explode. Ive had hot coffee cups explode in the sink. Im sure there was less of a temperature difference there.
This may be because pyrex glass has a smaller coefficient of expansion than ceramic and therefore can remain in one piece during a temperature change
@@BackMacSci i assumed is was regular glass. Even still, its crazy Pyrex can handle such a drastic temperature change. Thanks for the answer.
I love the wire demonstration. It's accurate but I have a feeling it confused a few people too. Your energy is infectious though and I love the editing. I love your donut sphere.
Thanks for the feedback, man. I’m hoping to make my channel more educational so it’s not just visual stimulation, but empowering people with knowledge. Was it too confusing cuz “fields” are inherently abstract or could I improve some part of my demonstration? I bet you noticed, I didn’t through any equations up there for the same reason, to keep things conceptual rather than quantitative.
@@BackMacSci I think it was great. Sorry if that came off as criticism. It was not. I was just watching it and being like "This is a good demonstration that is going to confuse like half of the audience" but you know, we are talking about invisible lines. I think Richard Feynman had a lot to say about that.
I think you did a fantastic job and I really genuinely liked the edits. I thought they were pretty and contextually appropriate and I think your videos are radhaus.
I was just chuckling a bit about your wrangling with wrangling it. I dunno. I think it's poetic. Also, yeah. I really like how you did the arrows.
@@BackMacSci As someone who isn't an electrical engineer maybe take the components and state what they are /w price so they can buy them online and slap them on/near a paper diagram. I think this would help a lot more than just saying a 10 kw ohm capacitor goes here as it would say this piece which looks like this goes at this spot in the loop. Overall though, I loved the explanation and it was very informative. Keep up the good work!
Thank you, yeah, I could have described the components more too.
@@BackMacScithank you
I love that you add little explanations and definitions throughout the video. I don’t do much with electrical stuff so it’s extremely helpful
The best kinds of YouTube videos are the ones that inspire people to go make stuff, and this here is an amazing example of that! Twenty minutes ago I didn't know this was a thing, and now I want to build one! Can't wait to see what improvements you make, and what projects you tackle next.
Also, very class-y explanation of the class-e oscillator! And I love your method of designing/fabbing PCBs. Keep at it with the acid etching, the ability to make PCBs at home is priceless (not to mention a huuuge flex)
I've never become a Patreon supporter before...until now.
Your videos are excellent and you supply files for how to etc.
You have a massive future in science communication, and as a science educator myself, you have a natural talent for explaining complexities.
Looking forward to more.
Hey Andrew, seeing this now. Thank you very much🙏⚗️🧪
This is one of the coolest things and best explanations I've seen on YouTube. I'm not familiar with Tesla coils and so I was wondering why you needed such a heavily analog drive circuit... Until you explained that it's running at 15MHz! 🤯
Really enjoying your channel!
So glad to see you test out the coil orientation to test for convection. That was an interesting result.
Nice to see it still stay locked to the coil in the way it did and was just compressed due to the convection.
Best of luck going pro, dude! You clearly have a passion for science and find joy in discovery. I hope you continue to share this blessing and inspire others. Good stuff brother.
I'm looking forward to seeing this channel expand, it's been a while since I found a fresh science channel
The editing is amazing, and the explaination is also very good, i liked this a lot
Man every video you make on this always intrigues the hell outta me! Absolutely beautiful!
Maybe see if you could use the plasma toroid as an artistic oscilloscope. If you could fine-tune it so you could see a physical representation of modulation with a base band tone for example, that'd be pretty sick.
DUUUUDE that would be doooope
@@quandarkumtanglehairs4743 it would also be the first developmental step for him to design his own device for playing music through the toroid (considering bT failed)
His parents that got interviewed at USC led me to his channel 😂
An interesting video idea would be to test how different shapes of the glass would interact with the plasma. Maybe it would form interesting shapes if you use a spiral or a tube…
I love your content and i would love to buy one of these.
dude! that is mesmerizing!!
and your video achieve some kind of perfection of "getting to the point" that is very hard to find on youtube!
love every bit of it!
good luck on your project!
You’re such a wholesome person, you deserve to be appreciated and happy in your endeavors.
Thank you very much🙏 God bless you
I really want one of these. I would love to see a kit. I also love the idea of experimenting with frequencies

Loved this video, great to see your improved version.
Great work, and great explanations! I really enjoy your videos on this project. Keep it up!
I very much like your explanations in this, fantastic vid. I’m not very good at electronics but I actually kinda got that about the mosfet resonance zero v thing!
Suggestions: If you can get all the input frequencies to match (or maybe be a multiple of) the xenon’s natural excitation frequencies, you might be able to get a lot more effective power to the plasma itself.
Alternatively, a ring of a few electromagnets around the globe, powered in a sequence like a coilgun. Might be interesting to see particle acceleration with novel electromagnetic confinement.
I really want to build one of these-do you think a variable frequency zvs driver will work for the radio frequency supply?
You could try it, yeah! I wonder what the lowest oscillation frequency is that will sustain the plasma ring.
Nice work dude, you've done it again! The audio modulation was definitely a nice touch!
Thanks Zach! I hope to actually get it musical soon.
All the Best Bro 👍. You are doing great stuff man! Keep it up.
it would be really cool to see what happens if you would use two oscillators on the bulb at the same time if it would be possible to make even crazier shapes of the donut that way. that or the two circuits gonna disturb each others fields is my guess
i believe the later yes, they do not like other fields
@@BotchedGod there is only one way to find out right ;)
It looks like everyone is using a Steve Ward circuit as the power source. Are you planning to discuss the circuit specifics in this upcoming vid? I know @kcakarevska recently shared the Steve Ward HF Plasma Driver circuit revision 1.0 from 2022. I believe the Steve Ward circuit is up to revision 4 or 5. Is there a reason you're using Rev1?
If you’re hoping for circuit theory in this video, it’s at the end of this video, Nate. The ward toroid driver is just the plasma flame driver with no “secondary” and altered component values, so yes, we are using the circuit published at kcakarevska’s page still.
Awesome! Thanks again. You guys are doing an amazing job with your improvements!
This is seriously the coolest thing I’ve ever seen.
I wonder if introduction of fields at additional angles would influence the possible loops able to form.
Perhaps through interference of different frequencies some really exotic shapes could emerge.
Anyways, very cool. Favorite channel I’ve found in a very long time!!
I LOVE finding channels like this! Keep going my man - I see 1M in your future.
I really hope you can commercialize this because I really want one, but also don't want to die of electrocution and internal radio frequency burns trying to make my own 😑
you prob won’t die but maybe surface burns
no pain no gain, how else are you supposed to get a mad scientist hair if you dont electrocute yourself a few dozen times
I thought that that plasma toroid video was somehow faked until you made your videos because it looked too good to be real. I wonder what happens if you use different Gases like Nitrogen
It will work with any gas according to the papers from the 1950s. And the color and behavior of the plasma would largely depend on the pressure of the nitrogen.
@@BackMacSci Wil it work with O2
Good luck dude!
Excellent circuit and design. And execution. And explanation.
I definitely had to sub after checking out your videos. Ill be looking forward to more
So stoked I found your Channel again! Your back!
Thank you! I am!
Fascinating project, but please stop wearing gloves when you use a saw or press run by electricity, if the glove catches the blade, it will deglove your hand removing all the skin of all your fingers leaving just a skeleton and no muscle. It’s a really ugliest thing to see when it happens. You need to use push blocks to use pliers, or hold it with a tool to give your hand distance away from the sawblade and drill press has enough muscle to do this. That’s the reason they make vices to mount to drill presses. You were safer doing it barehanded than wearing the type of glove you’re wearing that holds together very tight that if it got caught in any of these devices, it would remove all the skin and muscle off of your hand because . It took six years for me to get 85% of the use in my hand back from an accident at work. And I have never gotten 100% use back and that’s the best case scenario.
I agree push blocks are way safer
This is great! I especially appreciated your description of how a class-E oscillator achieves ZVS - you were doing a fair impression of how I'd expect a TA to handle a lab session on oscillator fundamentals (ie colpitts, pierce, armstrong, multivibrator, etc). I look forward to seeing more pretty dancing glowing plasma goodness in the near future.
Honestly I think he’s professor level at this point. I’ve not had a TA that’s built the things he has.
I’m definitely going to give a go at building one of these after I finish the 50 other things I want to build. Yours is just so cool!
Thank you Ethan’
Beautiful project! Interesting about the mosfet switching at the 0V point. Have dealt with this on thryristor firing circuits, but hadn't thought about it being a factor in a very high frequency design such as this.
I will support you anyway I can, Thank you for your time
Great little project it looks awesome, i find all this stuff fascinating, good luck with your YouTube channel!😊✌️🏴
12:09 that was amazing and mesmerizing it is also satisfying to watch the plasma form love it
At 6:15 “dancing more” sooooo awesome!
Beautiful build; plasma science is fascinating, thanks for your channel!
Thank you so much! I love it too and I look forward to exploring it with you all!
Beautiful, even more impressed by the stable ring, I just may have to make myself one and tool with it, perhaps using a universal wound coils that ive been experimenting with. Good job man.

@@m.sierra5258 It really wouldn't. Your router or microwave probably causes more RF interference than this.
