- In this video, I test out my homemade High Voltage Capacitors using two microwave oven transformers (MOT's). They are ideal for spark gaps used in Tesla coils.
I also have a video showing how to make these capacitors
• How to make a High Vol...
Thank you for a nice presentation. Normally capacitors have two important things, 1. their values if uF, pF, and nF, and their working voltages, WV. It would have been a nice piece of information if you had tested these for a high voltage where it breaks down, meaning the arc jumps through the plastic of the bottle; I can imagine it is very hard, you might need 20Kv or higher, but the value would have definitely helped in understanding what size is suitable for someone wants to design it. For example if these are 10nF then definitely changing the width, and diameter of the pipe would make a bigger capacitors. But anyway, thank you for sharing your knowledge. We can do the rest of the experiment since yours gives a good push to move on. Keep up the good testing. Thanks. I liked your video.
Thank you for the positive feedback.
Great demo wow you really Sparked my attention,I'll have to build some of these thank you!!
WOW Lot of energy there, cool
I thank you people for subscribing.
MadDoctor Whitson could a man make a stick welder out of that set up ?
MadDoctor Whitson would that capacitor hold a small charge, to light a led for a second or two with out power?
I don't know yet.
@@aaaricmondroofing1703 No stick welder from this set up. It requires breaking apart one or two of the transformers, and replacing the primary coil with thick ass wire. Look it up on youtube.
Thanks for the vid man.
Mr. how long the electric current in the six capacitors that you made can last to flow electricity to other electronic media if the electric current from the transformer is cut off. thank you. good video.
I'm not sure what you're asking.
Good idea to use plastic soda plastic. Could use the bigger version of it and larger size alum can.
Do you think that can work?

I am trying to build a power supply with all diy part except the FWB...
May I ask below capacitor geometry questions?
Bigger the roll (bigger diameter) make higher capacitance.
More surface contact to + and - leg make higher Amp capacitor.
Does longer the cylinder roll make higher DC voltage?
That's an amazing idea you have. I really don't know, but you tempt me to try something like that. Aluminum cans would hold a greater charge, thus the plastic should be thicker in order to keep the capacitor from short circuiting. You mess with uncharted physics according to my books. Please be careful.
Hi,
I want to ask if you measured the capacitance?
How many Farazi was resulting?
What tensine can flow constantly?
I'd like to build more supercapacitors to power a DC engine for as long as possible.
Did you try to get 3000 Farazi at 2.7 V?
Thank you.
Unfortunately, I have no way to measure the Farads of these capacitors. The capacitors were just good enough to replace lighten jar (saline capacitors). They served as a dry alternative and took up less space in comparison to saline capacitors. Saline capacitors are risky, because they can spill over and short out HV equipment. Like I said, I was just trying to replace saline caps..
sweet man!
Yea, how about an explanation of what and why its happening .
Plasma arcs... These are usually blue because oxygen burns blue when making O3 (ozone) gas. This gas is poisonous to humans, but smells sweet as it ruptures all the living cells in your nasal cavity, full of microbes. Like H202 (hydrogen peroxide) smells sort of sweet when it ruptures the cell bodies of microbes, blood, and tissue in wounds. O3 is a good air purifier used by crime scene cleanup crews and hoarder cleanup jobs. It also neutralizes many carbon compounds in the air in polluted spaces. The current is literally burning the air gasses, hotter than fire. Fire is seen as a low temperature plasma by some physicists. Friction from the current pulsating back and forth from the Alternating Current, as the electrons use the air gases as a medium, causes so much heat, there is a fusion reaction generating O3 gas from stray gasses in the air. It is electrical combustion.
When you used 3 caps and the spark was shorter than 2, the 3rd cap probably had a short in it. Not only not functioning, but draining the other 2 as well.
Thank. I'll keep that in mind when using crappie caps in the future.
@@maddoctorwhitson
That was a guestimation. I really have no clue.
I have Ph.d in nofuckinideology. lol
Btw. Have you tried the 12v auto coil with big caps yet? I used a wiper relay single post n/c cuz its still direct. But for 12v, you can pull out some decent spark.
And about 3 weeks ago, they had an electronic scrap collection in front of the supermarket. $5 got me 4 nice sized MOTs. The guy wasnt supposed to sell them, so I had to open them up fast and start yanking and kinda put the shell back on l. Those safety screws piss me off. So I got a iron mallet and chisel. To keep the shell from popping back off, I center punched the corners since the screws were gone. Lmao. I didnt matter anyways. They saran wrapped them on a pallet when they get enough of them. But $5... Good deal. Believe it or not, none matched in size.
Is that important?
@@AngryHybridApe, I don't believe size matters when it comes to voltage, but I think that the larger ones might draw more current (unsure). What I do know is that the small MOTs' tend to overheat much sooner than large MOTs' because their core can't absorb as much heat as the larger ones. It's kind of like how high ohm (small) resistors tend to blow sooner than low ohm (large) resistors.
@@maddoctorwhitson
Yeah. Thats what i figured. I think the smaller ones have aluminum primaries too.
But something tripped me out a few months ago. Someone tossed out a microwave, so I grabbed it, opened it up...no MOT. And there was no place to put one, so I know it wasnt already removed. It looked like it ran off a flyback generator instead, however that works. And it was a small one at that. Very disappointing. So I gotta wonder if theyre going to start making them all like that.
You can go on to build a welding piece of equipment. Great.
Thanks. I strived to do that some years ago. Maybe in the future.
Your experiment is cool, but show us capacitance, voltage and surface area.
Thanks. I will try if next time.
Will this design work for 12 to 24 volt DC systems? Also to get 1 farad capacity how many layers would I roughly need to later up?
G thoman i hope your beinv sarcastic
I used a VW ignition coil and put a wiper relay to simulate AC. Got some real good spark. And if I figure out what sized cap I can use to replace the condenser without frying the coil, Im sure I could get alot bigger spark yet. One coil puts out 2200V. About the same as MOTs. And now im thinking dual coils. If dont get back to you to let you know how well it turned out, check the obituaries.
Theres a few videos on youtube with 12v coils for Darwin award candidates.
Doesn't work for low voltage ranges.
how do i know the polarity of this cap?
Whichever end you use. + will be + no matter which end.
if you want to make a polarized capacitors, then use copper and aluminum. Look for their atomic number, the higher atomic number would be positive. You can use, aluminum, copper, gold, silver, or tin. up to you.
@alocin100 Thank you!
But you can make all in one why all that work
Why all that work... Cause it does. I take it that you don't know English that well. These capacitors work similar to lyden jars, just they are smaller in size, but a greater fire hazard.
Reluctantly crouched, at the starting line....
I was too sober. Other videos, I'm too drunk.
can you actually try explaining this ? ''''' what powers microwave transformers hows it wired ' just obvious questions us learners would like to know .
120 Volts AC from wall outlet.
Microwave transformers, or MOTs are awsome. Theyre also extremely dangerous, especially with capacitors in the circuit. BE CAREFUL, AND NOT CARELESS.
MOTs have a primary and secondary coil. The primary is the coil with thick wires. The ends of that coil takes in 120VAC. Dont worry about the coil in the middle. The coil with thin wires is the secondary. This coil puts out around 2000VAC. Coils have to have AC to work. Because they're on an AC circuit, capacitors are great for doubling the voltage. When the cap is connected to the secondary in series, current flows one way through the coil and at the same time fills the cap. When the current goes the opposite direction, the magnetic field that was created collapses and the current in the cap discharges back into the circuit. That curren plus the current that is now going the opposite way is now doubled. After it discharges and cycle starts to reverse again, the cap fills again. Current reverses, cap discharges and recharges, current reverses, cap ....and so on. Adding caps to this circuit increases voltage as it stores more current. As long as the caps can handle the V/A or wattage and can charge and discharge each cycle, they can be doubled. They usually only put one or two caps in a microwave that are matched for its purpose, but this circuit can be modified for other puposes like welders and killing yourself.
Again...BE CAREFULL. DO NOT FORGET WHAT YOU ARE WORKING WITH. This can kill you and not even say it's sorry.
Look up MOTs and projects for more info.
Fake fake! This is not true !!!! One single MOT will arc much stronger than what you have here? each MOT will have around 2000 volts and a very hi arc ! I just don't undrestand your point with this so called capacitors here! you should realy demonstrate this so called "capacitors" by charging them and discharging them on thier owne, or at least to see if they will light up any lamp. Or you could use a multimiter to show how much of capacitance this capacitor has!!!!!!!!!!! Pople Please don't do what this guy is doing here ! this is very dangerous!!!!!!!!!!!!!!!
The capacitors were reducing the amperage. That's why the arcs were much smaller.
it's like you literally try to tire people out with your voice
You know ASMR is a thing. Boo yah... Mad Science ASMR!
I used 31 volts its crap and shitty doesnt work
I made it correclty
They only work with high voltage.
@@maddoctorwhitson Oh ok :( Im just A kid
put thanks does it work with stun gun mudules
oops i think the arcs reached the foil
@@maddoctorwhitson Actually nvm its working its Actually a desgin problem
