Corona Discharge Photography
Вставка

- In this video I'll show the technique of "Kirlian Photography", which uses corona discharge off a conductive object for imaging. The technique uses two clear glass plates with salt water between them. The salt water is connected to a high voltage, high frequency AC source. An AC flyback transformer works for this, but i got better results using a solid state tesla coil operating off a slayer exciter circuit - the same circuit i demonstrated in my previous video. This generates around 40,000 volts at 350 kHz with a 12V input.
The high voltage AC doesn't conduct through the glass, but causes high voltage charges to appear on the outside surface of the glass plates through capacitave coupling. Because glass is an electrical insulator, the charges can't move freely along the surface, so when an electrode connected to ground comes near the glass, the resulting discharge "fans" out, as charges from a relatively large area will jump to a single point electrode.
When a flat conductive object is pressed against the glass, the edges and small bumps on its surface will exhibit this type of discharge and glow purple. Since the glass plates and the saltwater are transparent, the resulting glow can easily be photographed.
This results in some extremely interesting and visually impressive effects, but is mostly limited to flat conductive objects like coins, keys, blades, etc.
I've seen some videos that use acrylic insulators for doing this - which I strongly advise against, because the discharges will heat up and melt the acrylic - leaving a permanent mark or even burning a hole through the sheet.
Also, if you want to do this project and you're building an AC flyback, be mindful of the secondary coil inductance and its resonant frequency. I found that by having an enormous turns ratio at a high frequency, the transformer operating frequency was actually well above the resonant frequency between the coil and any parasitic capacitance - which causes tremendous losses and erratic performance - this problem is avoided with the solid state tesla coil.

Interesting project and very cool footage. While watching (for example the coins) I really wanted to have a closer look at the micro-discharges that were dancing around on the surface. If you get the chance, maybe try a closer macro shot or show it under a microscope. I think you will be able to record even more spectaculair imagery.
Might be tricky to keep the camera safe though
@@TiagoTiagoT You mean it would jump the camera/device? that be a killer i rekon.
For anyone who doesn’t know, @HuygensOptics has some of the best content on YT for optics. Highly recommended.
"It leaves burn marks on the outer layers of my skin."
Now, that's hard-core!
Oh man, this would look beautiful as a store front if scaled up. No digital blandness, pure real gas discharge generating beautiful colours and wonderful moving textures.
Wow, really interesting! I've never seen this before. I came to this channel for the submarines and stayed for all the other cool stuff you do 😁
I always wondered how this worked, thanks for the explanation and demonstration. By the way, that coin isn't a "British pound" but a 50 pence coin. You need two of them if you want a pound.
That's what I was thinking if only I'd be twice as rich!😂, just kidding I'm not remotely wealthy I'm skint!😂😁✌️
But a whole pound would break the glass!
if it were half a British pound it'd be 8 British ounces, or 1/28th a British stone
Awesome content lately HSP... I commend your work, very inspiring!
Very interesting. Like nature's way of "dithering" those coins!
You,sir,are a legend.🙏❤️
why isn't this channel popular. this stuff great.
I love how it crystallizes
This is a bloody fantastic video 💪
Mind blowing effects...
Also weird thing as I was just watching other video about corona discharge when you uploaded this video and now I want to make one of this, I think I still have my old high frequency AC somewhere as I was using it for other project...
Absolutely awesome project and the clips of the coins are amazing! What was the total cost of this project? I would be very interested in making something similar.
This look awesome, great work
okay well..
I take back what I said. this is absolutely sick.
and now I wish I had a coin collection.
amazing stuff man cheers.
I love this but it’s beyond my skill set. Thanks for these interesting videos.
Beautiful results 👍😃
This is great, I'd heard of Kirlian photography when I was in my teens and there were all sorts of claims made for it, that it could show the soul, a person's 'aura', that you could see ghosts with it and all sorts of other assorted 'woo'
Did I just get hypnotized? 🖤 ⚡️
¡Geniously crafted! Keep with this content!
Dude your content is really interesting and informative keep up the good work!
"Dude, I'm 14 and talk like it"
@@user-zq6pj5jo8j ?
Awesome video!
Simply beautiful
This is just SOOO kewl!
Interesting vid. Have been watning to make one of these for ages. BTW that's a British 50p, not a pound.
I really like your videos
Same
This would make awesome special effects for movies, etc.
Very impressive thanks!😁✌️
It reminds me of a movie call "Flight of the Navigator" When they return to the correct time...:)
One of my favorite movies from childhood; Imma have to rewatch that scene, thanks!
Thats was great . 👍🏻
Awesome video it would be interesting to see differant types of rocks and elements in this light.
This is Awesome ❤️
Very nice, thank you!
This is the coolest
Sir! That coin from the Brittish Isles, you identified as a pound!
'Tis no such thing!! 'Tis a fifty pence piece sir!!
I'm in love with that purple
It's ionized nitrogen. (Oxygen is green.)
Gas discharges are beautiful physics.
I built something similar back in the 70s, but it was only still photography using a car ignition coil and Polaroid film. People weren't completely clear on what was causing it at first, so the pseudoscientists jumped on it and started interpreting "auras" from the different colors. Thing is, if you stick an adjustable POT in the circuit, the colors changed along the spectrum as it turns.
Have you tried the torn leaf on yours? That would be cool.
So beautiful!
I think that you should drill glass under water
Sierra Nevada Represent!
Cool!
The Queen looks like that for real now!
Neato. I just love how everybody and their brother has 3D printers nowadays.
That "Bristish Pound" is a 50 pence piece. £0.50p
Love your content BTW. Subscribed
Fascinating! I wonder, could you do 3D surface height measurement / reconstruction by integrating arc intensity vs voltage?
You are a freaking genius
Might try using some of those electroplated leaves. That would make some interesting images.
👍🏻 Brilliant stuff, thanks for sharing! Did you try things like imaging a fresh whole leaf, compared with an image of the same leaf with a piece cut off? The second image reportedly shows a ghost outline where the piece is missing. That was my first ever introduction to Kilian photography, and I've always wondered if it was true.
If you had a British accent and dumbed these videos down by about 90 percent, you'd be getting millions of views per video.
How does this only have 18k views? I don't understand.
Great video, much enjoyed. But at 1:27, I believe that you've got the polarity wrong... a +40kV will induce a +40kV on the other side. The glass dielectric will accumulate (-) charges near the (+) electrode [ie salt water] and the other side will be (+) charged, not (-) charged.
SOOOO BEAUTIFUL!!!! Now if only Astronomers could start applying plasma and electricity to the universe around us :/
looks fun, i might give it a go.
Circuit diagram?
I still don't really understand how this works after reading the description, but it is very neat.
New video woohoo!
nice project!! Could be possible to match the image with the voltage applied to create a 3D topography map of the coins?
That is awsome and beautyfull, i'am fan of all your projects. Can you try building a metal detector or a coilgun?, with your skill at electromagnetic induction that can be easy for you.
Nice video .I was wondering If a tesla coil can be used for kirlian photography and i found your video.This high frequency ac is safer too ..
Would it be possible to make it work with skin contact without burning by using with lower voltage or perhaps some other modification? Perhaps using long-exposure to get the fainter glow?
Wow never knew about this
the Smiley Face at 8:50 looks like an album cover
Could a less powerful version be used to make self cleaning/steralizing windows or surfaces.
Hi.. Thats cool.. i was working with that kind of configuration. Instead using grounded electrode, i connected both water plates and metal plates (conductive thing) to each of the AC high voltage terminals (from the AC flyback coil).
i used 24V DC switching and zvs driver to power up the flyback.
i was wondering, which ground you used in the experiment? is it earth grounded connection?
thanks..
I wonder if you could see the magnetic lines of a magnet. Or how an ion thruster works. Maybe ion thruster tuning.
Idea: metallic paint (or other metalized coating) on a war game miniature. See how that works! Could also be an excuse to build a vapor deposition system if you want to actually metalize things with aluminum....
Great footage! Thanks! Question: Doesn't this work with DC HV as well?
if it's a capacitive effect, it wouldn't work with dc
Using HV DC sounds incredibly dangerous.
6:25 heh, unintentionally made a low pressure sodium gas discharge lamp in your input tube there ;p
Have you tried spraying an object with conductive paint? This could open up non conductive possibilities, you could print elaborate shapes then spray them.
"It leaves burn-marks on the outside of my skin." Any TRUE artist suffers for their art.
what would happen if you put the whole thing on a bed of coal? coal would be very dark giving great photography contrast, but i wonder if it would conduct enough to cause more discharge. like a coal electrode.
I think the best result was from the back of the Ohio quarter - it really looked like some kind of electron microscopy
Was this only uploaded in 720p? I tried reloading the video again after 12 hours, thinking perhaps I'd just clicked it too quickly after the initial upload, but it's still capping at 720
heaven forbid!
👍👍
can you please share your 3D files for the HV flyback coil? you have shown them multiple times but not shared them that i can find. i have a 3D printer but im hopeless at cad so cant really work from scratch
You might like the Safire Project
You kinda made an inverted what ya call it ? Those electric balls they sold in the 80s.
جميل
what’ the nake of the track at the end where you turned off the lights? is it “to the stars”? i can’ find it anywhere
I think the CFL was lighting up more from the coil than the sheet.
Ozone has a smell? Who knew! I’m curious as to whether you can get different colors some way. I do know that different gasses will allow this much like fluorescent lighting. Your device seems to operate with saline and is that’ where the purple glow comes from? Possibly using gases rather than water would create different colors
it has a very distinct smell and we can smell it just becfore it is concentrated enough to be very harmful.
Aren’t the electrons technically jumping from the grounded object to the glass and not the other way around?
Super cool too, I wonder what determines the color of the arc
I'm not sure, but I think one side of the glass gets the positive charge, that induces on the other side an negative charge, side that does conect through air to the ground object, so, it's eletrons jumping from the glass surface to the ground object.
I get the idea it's moving both directions - the electrons don't move *through* the glass, they just build up or deplete, so it needs to be an AC current or it runs out of electrons and stops working.
I'd love to see if Damascus blades would look differently than a regular carbon steel or similar blade
Was some of the coin image showing during the wrench display?
What would happen if you built this into the front of a fish tank?
I used to work at a fish store and people were always tapping on the glass, smudging it. This looks like a nice drterant!
If you do that with a leaf and first use the whole leaf, then cut it in half but don't move the leaf, take one half away and put the high voltage on it again and watch the cut off part of the leaf magically come back as if it never was away.
Would it appear differently if you changed the "air" gap gas? eg Argon or Helium? maybe not Hydrogen😅
need to try it with a big flat piece of Damascus
So if I wanted to burn off fingerprints in a cool sci-fi way I should build one of these right?
It looks like there are some places on the coin where the pattern of illuminated dots is steady, and other places where the dots seem to be moving. The stationary vs moving regions seem to change somewhat with frequency or voltage (I am not sure what is being adjusted in the video). Does anyone know why there are both steady and "dancing" regions?
Is a dielectric barrier discharge (DBD)?
Is there any way to do this , but no pain in the fingers ?
اين مخطط الدائره يا هندسه
at 5 min. . . i really laughed out loud.
Try some thin steel wool sheets cut in patterns...*or brass wool.
Could this work with flowers ?
Can we get the slowmo guys on this please
If you raise the frequency does it hurt less?
Also how do these things act in a magnetic field?
i have a question~ first, is there AC flyback transformer? i know that flyback transformer is DC source.. second, if capacitance is changed by something of ground, can tesla coil operate well? resonant frequency will be changed I think.. i want to know what output of your AC supply~
yeah don't try to drill through tempered glass. It would have worked with normal glass.
Spectacular.
I wonder what causes the change in intensity across the surface when using flat material (such as the blade 08:17)? Can it be used to show oxidation/faults/grain structure (if environment effects are eliminated of course)?
Pointy things concentrate electrons. That's why a lightning rod is pointy. In theory it ought to reveal microscopic cracks in metal.
What are the materials required for this?
Just fyi, that image of a key is clear enough that it could be decoded and a copy made
Oh yes, this was how Krilian phtography was done in the 79-80'. Crackots believed these photographs showed Aura around living things: en.wikipedia.org/wiki/Kirlian_photography
