Building a X-ray powersupply 

"well, to make sure we don't fuck up anything..." Best segue ever! 😂

I'm not really an electronics or physics guy, but you made this really interesting.

When you rewound your primary it’s likely that you adjusted the number of turns around the core which especially on a flyback will have a big difference on output voltage. As an example if the transformer had a 1:100 winding ratio then 10V on the input would be 10KV on the output if you put 2 windings on then it’s effectively halved to 1:50 and you’d only get 5KV at your same 10V input. So less turns = more voltage but also increases the risk of internal arcing of the transformer and overcurrent from the ZVS.

In printers, the high voltage (from a corotron, for example) is divided by a very high-resistance divider to a value that is suitable for the PWM controller. Then a buffer op-amp with unity gain is installed to match the impedance and then op-amp output goes to the feedback input of the PWM controller. And the PWM controller, in turn, controls the power supply of the high-voltage converter, or directly (through a driver actually) its switching elements (MOSFETs or IGBTs). This allows you to set the output voltage with sufficient accuracy.

The effect on the oil and sand is amazing

It would be useful to add a resistor for high voltage (and low inductance) to the output of the multiplier. By limiting the current a little, it extends the life of the diodes and in case of electrical discharges it prevents dangerous inductive spikes in the circuit.

Really cool stuff. I'm at this point trying to figure out how to power an old motor, and make an switch for it, and you're making this instead? Crazy!

So refreshing not to see a video on RU-vid where I feel dumber than when I went into it.

Try using a flyback from a gas grill igniter, the battery operated ones, not the piezo ones. Drive with zvs and feed output into multiplier, scary loud output from multiplier

Nice psu But using a buck converter to power an LED kinda broke me, using a series resistor would have been much easier. Also add some filtering before the ZVS as the "DC" from the rectifier will be pulsed. A capacitor will help to get a more smooth DC and maybe more output.

Despite I am designing electronics for living, I am still afraid of building high kV sources at home.

i'm getting deja vu again

Thanx For The Info!!!

That coronal discharge to the pliers!!

Your one step away from building electrobooms magic wand lol

3:20 my thoughts exactly when i built my own multiplier hahaha what x ray tube do you plan on using? i have used a $10 2x2A rectifier tube with no joke about 100kV across it and it did not burn out / overheat the heater filament. to use a very cheap tube, u need to have a high exposure time on your camera to really brighten the image to get decent scans

you should make a video on the synthesis of pure N20

Nice. Really fun stuff. Cheers

Amazing job, I may build something similar.

No current limiting? Unless you're running a very powerful X-ray tube (which has dangers of its own) you may as well limit the current. Makes it less likely to kill you should something go wrong.

Does the sand pick up the charge to align into patterns because it's silicon, or would any similar granular substance do the same thing?

Can you X-ray me? My leg has been broken for about a year and I can’t afford going to a hospital

Your numbers are way off due expecting breakdown voltage of air to be the relevant number (3 kV/mm). Due Townsend avalanche you will see arching with bit over 1 kV/mm.

So do you believe that if i were to say connect a high powered taser to a vacuum tube or X-ray tube that could in turn make a sort of hand held x-ray machine? Theoretically

Brah, where are you located? I seen your 5 htp > aeration video and went hey cool but your xray vac tube seal team 6 arc arc arc setup and this and your humor and geeky-ness-is-esses... Are you my. long lost brother? Ive been wanting to build some fun explosions and ire 😎 Edit: and hho... Srsly have I been cloned? With arduino things and more... Esit2: rockets, hydrazine, deadly pigments, yep you have my dna 1:1 da komrad! Very nice how much? And your hydrazine let's make a hydrazine rocket BUT with *the pointiest tip ever to scare the enemy* maybe I got 23&Free DNA cloned from some fence or statue I touched hmm... 🤔

Nice video ,Man how much windings do you have on the primary coil and how much on the secondary in the diy flyback?

Have you ever zapped your zipper?

you probably should have led in the front

Why is it needed to put ZVS in oil? It is on the lower voltage side. I saw people on the internet driving flyback transformers from those aliexpress ZVS without putting them in oil

I am trying to build the high Voltage x-ray power supply and need about 100KVp for 5 secords, I find most of the parts but was unable to find the exact one in the video, that is, the flyback transformer, can anyone tell me where I can get the same flyback thats in the video. Thanks

plz make a zvs circuit plz

Nice work, I wonder if you could push the current up to say 1 to 2 amps? Did you fill the electronics box with wax? Do you have your set up diagram in block from?

can you write all component you used?

Hmm how crop circles are made possibly.

How many turns did you use for the flyback?

I really want to put my hand in it

I thought it was 1kv per 1mm 🤔

What type of oil is best to use for this? Generic mineral oil, or is there a specialty oil that should be used?

3:41 contact Honeywell and see if they'd pay you for some non sleep inducing ads for their products, 😂😂😂

Please do it, nice videos btw..

Rent a house nearby substation 220kv

smack!!!! we dont swear on youtube

Did you literally fill the entire case with wax?

Sorry but that is not 90kV. 3kv per mm would be with sharp points like nails, and probably in higher humidity and temp conditions. With the balls of steel it looks like probably 25-30mm, and it could very well be about 20kV or so.

As well as the obvious danger of high-voltage, X-rays misused can lead to cancer and mutation.

Is the high voltage dangerous to be near?

why not direct hv transformer to dc hv fbr-cap

Ionic breeze... In oil 🤪! Are you an only child? I would think you were, otherwise you wouldn't be able to have something like that around without some death or destruction involved.
