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!

[@ChopFooey]

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.

[@alexanderglass2057]

I saw the plasma channel and Inteza with their version of this, and my question and possible experiments I want to do if I get enough free time is see if you can do non circular resonators. If you could mess around with radio antennas as resonators and concentrated electric field zones around antennas with different amounts of poles, it might be possible to have a monopole whip antenna create a hollow cylinder around it and a synchronized dipole create a beam between the two rods. If we can mess around with this and start projecting in a planned direction from the resonator and ignite air with handheld systems... Well now we have real plasma light sabers, not the Hacksmith's very hot torches. And if you can send pulses that will persist for a couple feet separate the resonator down a resonator barrel now you have short range plasma weapons, likely to mess up any drones.

[@coyotedomino]

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.

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 .

Hi There! Great Job on the Plasma Toroid Generator! DEFINITELY WORTH A LOOK!!! To get the field to interact with music or sound in general... Could a small speaker or sound generator output be connected to the glass to make the Plasma move inside the glass... Or do you think the sound would not travel in a vacuum... But perhaps it would cause the glass to distort ever so slightly, maybe enough to make the plasma move in the desired way. What makes the Plasma Ring move at all once it is formed..? Fluctuations in voltage, amperage or resistance as things heat up could be in play..? What if you pulled a vacuum in the copper tubing and stabilized the copper coil with plastic clips? Really Cool Experiment and Regardless of who did it first, it doesn't take away from anything you did! Just look at how many people watched it! GOOD job with the research!

When you're trying to solder legs into the huge pads on your home made PCB, you should tin the legs first. Adding a blob of solder around the leg before attempting to solder it to the board. It helps increase heat transfer from the iron, as well as helps wet the surface so that you get nice adhesion. With huge pads covered in solder like that you're gonna have trouble getting the whole connection site hot enough to make a good connection, and you'll likely end up with a joint that is brittle and may crack and fail. You should also make sure to use some flux, even if the solder you have is flux core, flux will really help the solder wet.

Could a large clear light bulb serve the same purpose as the glass you used.

I only mention it because my understanding is most of the projects trying to harness fusion usually involve rings of plasma no?

Best of luck on your YT journey. You may be able to get some pretty interesting geometries and movements as well as just generally more control by introducing multiple coils at different orientation and adjusting your signals independently.

Thank you Danté, Steve Ward has experimented with multiple coils oriented normal to one another and the toroid behavior is sporadic and jumps from coil to coil, staying parallel with coil plane, but his experimental results are not published to the public.

[@------country-boy-------]

Awesome !!! Maybe try using separate coils - one for each current direction. It would simplify circuit design. Collapsing magnetic fields generate a voltage spike in the opposite direction but maybe that's not a problem for air cores. Spikes are usually shorted by a high speed diode or passed backwards through the inherent body diode of the MOSFET. If you got a function generator with multiple outputs you could just basically do everything with that and just amplify the weak signals with mosfets. Also a ferrite core transformer with single wound primary and dual wound secondary might do the trick to split a single input into 2 outputs (if you only have a single output function generator). Maybe use variable resistors to adjust MOSFET gate pull up or pull down. Maybe a coil could be placed on top of the bulb and one on the bottom of the bulb to help plasma float in the center. Might be able to play music in the plasma by playing audio through a third coil - just run the audio through an amp first - speaker coil to side of bulb ??? I have no idea. Anyways great video and great editing!!! I been working on an invention for about 20 years. I will make a video about it maybe next year. Too busy right now.

[@AA-gl1dr]

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!!

[@LevySkulk]

I have a few ideas for videos, mostly about the plasma toroid. It would be interesting to see what would happen if you introduce a second coil, would it be possible to make 2 toroids in the globe? They'd have to be separated enough to not interact with each other of course. As someone who's into audio design, I'm also interested in manipulating the waveform you're using to generate the toroid. If you've ever seen "Oscilloscope Music" you may know that combining a signal with a square wave duplicates an image. I believe in this case the square wave would need to be be very high frequency. Essentially using the same coil to generate two different electric fields with different positions/shapes and switching between them very quickly. I'm imagining a cool "stack" of toxoids, but it'll probably not be so simple lol. I think all sorts of additive synthesis principles may yield interesting results. Final toroid idea, having other electromagnets around the globe to manipulate the position/shape of the toroid, with some clever programming you may even be able to use external electromagnets to stabilize the toroid easier/faster. Non toroid idea, exciting Nobel gas/vacuum vessel with high voltages with samples of other elements placed inside can change the color, even when it's not a gas. For example, salt would introduce sodium ions and change the plasma orange/yellow. There has to be all sorts of solids and liquids that would add change the plasma interesting colors. Good luck on your KZbin career!

[@johnnymnemonic8487]

I believe the sound was actually the coil vibrating against the glass not the plasma. If it's AC current going through the coil, then it could be the Hz at which it oscillates. If the power for this thing comes from the outlet in your home and is unaltered from the device then I'm guessing the coil is vibrating on the side of the glass at 60Hz. As it moves the pitch changes from the vibrations carried through the glass. If it DC then there could be a vibration from the device itself and that vibration is being carried through the coil hitting the side of the glass getting the same effect.

It seems like putting a shorted copper loop on the top of the globe would help stabilize the ring - by Lenz's law, it would have the opposite current and flux, and would give you some push-back on the ring. You'd have to play around with the size and thickness of the loop, but it probably would stabilize it over a much larger range of drives. Don't forget that this ring will be dissipating some power, so it might get hot under some circumstances. I'd start out with smaller diameters at large separation from the lower winding.

thanks Scott! Would you like one of the element cubes? I think that shorted copper loop is a cool idea!

[@scottmiller2591]

@@BackMacSci I appreciate the offer - give it to someone else, and keep up the good work!

[@BackMacSci]

Thanks! And will do.

Thats really awesome dude! The best thing I ever did was use a 555 timer circuit to trigger a mosfet triggering a cars ignition coil to create a Jacob's ladder arc between 2 coat hangers. The transistor kept burning up so I then used an old ignition module from the 70s to do it. Cool channel!

Sick! I haven’t done that before. And thank you!

Chemical etch with ferric chloride. Use 3d printer to slosh back and forth. Also, use paint marker or something ontop of the permanent marker to better protect. A bit of heat form the printer heated bed can help too.

Bro its like your making flobber ! I love it

[@wesjohnson5204]

Thanks again great experiments!Probably answered already in the many comments, but the sound was audible when the separation of the glass and coil was in a close resonant range so they could talk about it.

Convection is what causes the toroid to float around. Convection also causes it to stay in one place while this device is also upside down. Modulating it with audio to play music would be epic!

You might try placing a coil around the center of the glass that might stabilize the plasma ring. Just apply a counter magnetic field at the same frequency as the primary, but adjustable power.

Great little project it looks awesome, i find all this stuff fascinating, good luck with your KZbin channel!😊✌️🏴󠁧󠁢󠁥󠁮󠁧󠁿

I would love to see the effect of two coils placed on either side. Does it form two toroid? What happens when the electric fields are switching direction out of phase with each other so they're always in opposition: because they would nullify each other at the center, would it make a sort of "8" shape? This simple ability to define a plasma's shape may be the first step to holograms, spurring the start of an interest for making high resolution electric field generators. I think I saw in a video's comments that something close to it has already been developed for some e-paper displays which use magnetic fields to turn multicolored particles so one color can be displayed, it would just need to be beefed up for the plasma.
