the circuit you built that is powering the tuube with the adjustments do you have a video or schenmatic diagram ? very interested in building one : ) thanx
Thanks for the walkthrough, Steve. So the primary is intentionally not driven at its resonant frequency to decrease the power transfer to the secondary and plasma load?
@@SteveWard I was wrong, caught in the lands between DC blocking capacitors and actual resonant driven transformers. It is only using PWM for voltage regulation and current regulation in done on the x-ray tube filament current. Most I have found, has a huge single 4-5 uF MKP capacitor, the size of a slightly thicker beer can.
X rays are not possible with the pressure of gas and voltage, you just can't accelerate electrons for long enough distance before collision. UV is possible but the borosilicate glass would block most of it I suppose. Biggest danger would be the implosion, I think..
I don't want one of these I NEED ONE So how safe is one of these actually? I had a small plasma globe and it used to shock me trough the base ornament in a couple of spots, I think the ark was jumping from the glass into my finger and into the base, the base wasn't conductive from what I know
Truly amazing work - very Impressive would love to make one - but I bet that tube cost a pretty penny unless you blew and filled it yourself (probably did). I would like to make a bagle ring maybe its the one I may make - but nobody will make a krypton filled sphere for me - - 😢 - anyway like a lasing gas has an exited and ground state - are you tuning the power supply frequency to the resonance of the gas or the cavity (tube) the gas molecules are contained in or both? Andy👍
The glass was made by a scientific glass maker, it requires exceptional skill and expertise and tools. No special resonance of the gas or chamber that I'm aware of. The gas pressure is tuned to form nice filament structures without needing too much power or voltage.
Have you calculated the power consuption of the unit? I am very curious as to how much power it uses. If I understood correctly from the video this is a beautiful 48v 200 watt light bulb drawing approximately 4amps an hour. Cost of approximately $0.04 an hour at $0.2 a kw?
That's awesome I tried to do something similar, i have a 5 toot glass tube, 2" inside diameter (from and exploxion proof fluorescent), i tried an electrode at eacch end and a NST, was hoping to get an elongated star in a jar type effect eventually, or just get some plasma like a cold cathode fluro.
Thanks for the interest, but unfortunately this is not a DIY level of construction. The glass work is handled by professional, and the gasses and equipment to properly fill one is very specialized and costly.
@@SteveWard Showing how it's done doesn't mean it needs to be at a level where ANYONE could do it. I doubt any of the videos that for example "Applied Science" publishes are in the realm of any DIYer.
@Alexander Gräf that's why Applied Science Channel is great. I'm afraid I don't have the same level of dedication and skill as Ben (or many others) for making videos, nor access to the glass shop where the stuff is made. You'll have to do *your own* research if you want to know more!
Fpga would certainly work but I'm using a micro controller to generate the variable frequency pwm and measure the current response in the transformer primary by using a current transformer and ADC to sample the peaks.
@@SteveWard Would be cool to see a pair of these as a visual audio level indicator showing the amplitudes. Seems that there is some sticking in the changes in arc lengths when increasing the frequency. Wonder if that's just due to the PD effects or ion channel that has formed from the longer arc lengths. Seems that the arc really wants to couple to the 48V power line above haha.
@Sam Catania yes, would make a cool bar graphic display element. Even smaller versions would be more predictable. I agree with your note about sticky spark length, that seems to partly be due to nonlinear response of the resonant system but also thermal convection within the tube has a profound effect on the plasma length and behavior. It's thermal convection that makes the plasma stick to the top, the wire is not a significant attractor.
Очень красиво Тоже была идея использовать кольца в качестве сердечника, но к сожалению не успел это проверить,(В связи с войной в нашей стране все эксперименты пришлось оставить и выехать.

Сочувствую вам. Я сделал DRSSTC со стивовским драйвером. Скажите такие трубки это из какого-то оборудования? Как их гуглить? Вы измеряли по ультрафиолету? Это ведь может быть очень опасно без люминофора...
that is so cool.
It really is, I want one yesterday and I was today years old when I found this
Awesome
Very neat. I thought it was xenon at first. The 3D printed multi-section transformer is nice.
So cool and well presented! Would love to see more technical details :)
the circuit you built that is powering the tuube with the adjustments do you have a video or schenmatic diagram ? very interested in building one : ) thanx
This is so damn beautiful... also the RGB plasma lights on Aaron Ristau's channel.
That is bad ass! The walking plasma is mesmerizing, i bet it's hard to not watch or just leave running, nice work!
beautiful
Wow, that's really cool!
Do you make those professionally?
that is very cool.
Very cool
What are beauty love this

Like a x-ray transformer is driven
@@KaizerPowerElectronicsDk do they use freq modulation to achieve regulation? I'd been curious about this.

If you'd put more structure into the video and showed more of the actual build process, this would be a candidate for 100k views.
Very nice setup Steve¡ Can it then be interrupter or audio/MIDI modulated?
that is beautiful, bravo... whats the risk of creating UV or even X rays with that thing, is it possible?
X rays are not possible with the pressure of gas and voltage, you just can't accelerate electrons for long enough distance before collision. UV is possible but the borosilicate glass would block most of it I suppose. Biggest danger would be the implosion, I think..
Could one have these as lamps ? Are they this noisy ? And is it fairly cheap to run?
Amazing
Does this lamp emit a lot of ultraviolet light?
I love it so much!
i want to build this for the makerspace i run, did you follow a guide?
where did steve go is he ok
What MOSFETs or IGBTs were used in the H-Bridge?
Just B.E.A.U.T.I.F.U.L.
I don't want one of these
I NEED ONE
So how safe is one of these actually? I had a small plasma globe and it used to shock me trough the base ornament in a couple of spots, I think the ark was jumping from the glass into my finger and into the base, the base wasn't conductive from what I know

How do I purchase one?
Can you make a how to video with the parts needed and the scaling possibilities of this?

I want... haha

@@SteveWard ah yes that makes sense. Looking forward to the next project.
Bad Ass!!!!
Anyone good at glassblowing? I would love to see this remade into an enegysword prop
Очень красиво
