Keystone Science hey greetings from germany:) maybe you can show a circuit that makes 110/220v AC from 12or 24v DC as an backup divise ? I really Like to build one but im not good in Electronics:(
I wasn't able to get this at first, so I plotted out each possible wire combination... there were twelve. I got it on the sixth try. Love this channel.
I'm a welder, and I think after seeing this video, it would be cool for you to make a video with a power supply of this nature, to create a small, portable, welder. Nothing extravagant, just something that could tack together something thin, like 20 gage sheet metal. Either that, or make a battery powered, plasma, soldering iron. Either of those would make my day lol.
The DC versions have the Cockroft-Walton array inside of them, while the AC versions have it outside as a separate unit. It is an interesting voltage multiplier which can be made into any number of stages resulting in multiplying AC voltages (into DC) by any number you want. This device can be used to feed a Marx generator for really high pulse voltages.
I hope that everyone notices that he was using the chicken stick the first try, but then was not using the chicken stick on his second try (5:46) and ended up getting shocked because of it. Always use a chicken stick.

you should make a heatsaw. it uses NiCr or nichome (the stuff insids toasters and ovens) that converts electricty to heat with profound efficiency. a fully mobile self-contained heat saw would be dope.
The stable purple arc looks more like AC. Normally, with DC high voltage, the arc is irregular and loud. Is it possible the tripler in this high voltage transformer was not working? I made similar high voltage device from compact fluorescent. I let the fluorescent connected as a way to indicate that the circuit is still working. I connect the primary of the CRT high voltage transformer in series with the main inductance of the compact fluorescent.. Doing this, there is no question about overloading any part of the electronic. I like the videos you made (I just found a link today, watched about 5 videos). Contrary to many other youtuber, your projects are working for real. It is not click bait with clever video editing. I would like if you would use the standard 10^3 names for resistances, frequency, etc. For example, 5 kilo ohm instead 5 thousand ohm (or say both if you think it would allow other users to understand better).
4:42 It's a good practice, but the longer the stick is, its easier too loose control on it, slip it, and make high voltage short :D I advice using medium one, with caution and common sense.
It's no where near efficient because resonant frequencies of CFL LC tank and flyback don't match. It will drive power through a Flyback but not efficiently like the DC square wave the TV circuit uses that is at the 15 kHz or so flyback resonant frequency, unless it's a computer monitor/small TV flyback which can be 30-45 kHz or more. Most CFL's operate anywhere from 25 kHz up to 100 kHz, but avoid the 32 kHz range so as to not interfere with remote controls.
Yeah I have a problem. I want to re-create this project but my Flyback transformer has 4 PINS, witch is confusing, but I have the connections marked secondary+ secondary- and Primary. but how am I gonna wire this? and I don't have an old TV so where can I get that exact flyback transformer? Please let me know. 👇😃
Ehh, voltage delivers it, but current is ultimate what kills, kind of? It’s really power so it can be viewed in so many ways, but ultimately the flow of electrons is what does it
Keystone Science Thanks for your answere! Yeah ur probably right since ur like really smart. I dont really know what im talking about so i’ll leave the job about electronics over to you, thanks again.
No, if you hook the output of one CFL to the mains input of another you will fry the other, most spectacularly. You can't use them in parallel either. If you want more power go with a higher wattage CFL, or go with a true flyback driver like the ZVS driver. I've used a 55 watt large CFL circuit, equivalent to a 300 watt incandescent lamp, with some good results. An electronic ballast for large straight tube fluorescent lamps puts out a lot of power but only the largest and most robust flybacks can handle it without shorting out internally. If you do go with a more powerful driver please make sure you know what you're doing and be careful.
Have you considered immersing the cfl circuit & the flyback xmfr in mineral oil?Also you can add a 30kv or larger capacitor from the flyback xmfr output for larger sparks.
Does it matter the wattage of the CFL bulb you get the board from? Using a high voltage transformer from a CRT TV, why not rig up plazma display inside the CRT so it can be seen jumping around all over inside the screen? It would be impressive yet safely contained.
Ah, it does matter what AC lead goes where. I would advise to have the Live connect to the red wire and black to netural. Also use a polarity style plug, the bigger side (Left side) is Netural and the smaller (right side) is the live side.
Maybe you can help but I have tried your configurations with the flyback transformer and I didn't get any arcs. Also when I took my multi meter to test the connection of the flyback for the large secondary the large the wire didn't beep with any of the pins so is my flyback broken or is there a secret I am missing
I tried at least five times to use the CFL circuit but for some reason, it wouldn't power the flyback transformer. Using a light ballast worked finally got it up and running.
Hey, isn't CFL-circuit's output also AC so that it can drive transformer? I had a couple problems with setup like this. First, all my CFL circuits could detect if there was a tube attached and worked only if it was. I found that putting a capacitor across a pair of pins attached to the same end of the tube (to heat electrodes?) works fine, and shorting them with alligator clip did the job too. Next, if i play with HV more than few minutes, transformer on a circuit starts getting very hot and then something on the bottom side burns up/explodes (i think some CMD resistor gets damaged by heat). How can i work around the overheating? Maybe a circuit from more powerful bulb would last longer before dying? or was it that i shorted these pins?
Nice work. I love the way you explain everything with their proper working science. Bro I've a suggestion for you- If you connect a starter(it was used with old fluorescent ballast that had only two output pins for the tubelighr)in parallel with the primary coil then the output will be 2x higher in terms of voltage. You can use it with flourescent ballast or even with cfl ballast. But I don't know the reason for it's working. If you could please explain it explain it I'll be happy. I have a question- is it necessary that the primary of the flyback has the highest resistance? When I connect the input of the flyback to the first two pins from the right (U) the arc is 1 mm long but when I connect the input to the 1st and 3rd pin from the right then the arc is 1.5cm long. Is it that the primary is the coil between 1st and the 3rd pin from the right?
Hi Keystone! I have been reading some information about T.T. Brown (Thomas Townsend Brown.). His experiments involved using high voltage 20,000 volts and higher with conductive materials inlaid with non conductive materials (as in metal and wood held together with beeswax in 8 alternated layers) to create a force that caused it to move. Is that actually a thing? Can high voltage create a force that can propel an object? If so. Can you show is how that works? I ask a lot I know. But it sounds so cool! Thanks KS! You're the best!
Maybe I missed it.. but what was the purpose of taking out the circuit from the bulb? What purpose does it serve in this exactly? Is it just to start with a higher voltage than mains?
l make flyback from odd tv transformer driving it with 85w cfl but when l connected a capacitor across the primary the output voltage increases but suddenly the cfl blow, why did it happens so?
Ok,...so,..how are the "arc" igniters that are used in the 'torpedo', or "salamander" type of heaters made? The electrical arc, is what ignites the kerosene, diesel or propane,..& this arc, IS, "running" for as long as the heaters are being used. How are the igniter modules constructed..so they CAN operate for so many..MANY, hours of use, "without" constantly "burning out??"

Keystone Science help me it worked but i had to plug the power in and out the hole time
Jackson Curren They ARE dangerous
Keystone Science OK I will join
Keystone Science I joined :3 Btw. You make soooo cool Videos! Keep doing so nice Videos!
Thank you so much! This is way easier than building a driver circuit myself
CRT "Can be shocked" LOL that's an understatement. As always EXCELLENT video !!!!
+duf101101 haha xD thanks!
every time i learn something new . Happy subscriber
I wasn't able to get this at first, so I plotted out each possible wire combination... there were twelve. I got it on the sixth try. Love this channel.
"and see which one it arks t-- Auw! okay..."
5:46 BTW

Welding requires very low gauge wire in order to not melt, making it difficult to make a mini welder
I am lousy at building flyback drivers. This looks simple and handy enough for just testing bulbs and farting around. Thank you, Dr Keystone!
I did this with a flyback transformer from a 5 inch CRT. Worked perfectly!
You are now the official High Voltage guy.......Keep it up......
This is the stuff I wanted to build as a kid. Thanks! Im gonna build this!
Any time! I am glad :)

This is an idea I must try - thanks for your comment/suggestion!
Wow this is pretty cool and it's pretty easy too!
underrated channel
awesome! I've been waiting for something like this
شكرآ جزيلا على هذا الفيديو المفيد . تحياتي لك من تركيا.
Another fantastic video. Keep it up bro. Also, sick pen, haha.
thank Tommy!
a DC to AC easy homemade inverter .. i like those
you should make a intro to electronics series
Your videos are great young man keep it up. Been tinkering my whole life. ☺
Thanks for the video, I'm trying to do this by myself 😁🤘🏻
Notification squad, Anyone else? :)
Circuit's Everywhere yep :D
NateBlanous :D
The project is nice I was seeking if you could come up with a video showing how a joule thief circuit works🎉
Keystone, at one point in the future, we should consider a collaboration. Love your work. We specialize in HV up to 500kv.
+Plasma Channel yeah sure that would be fun! I'm down to any time!
Private message sent, good sir.

This driver is preety good but it feels better to make your own zvs driver circuit
Great video! how about showing every one how to build a bug zapper!
Really amazing technique!!!
I liked it very much!!!
4:42 It's a good practice, but the longer the stick is, its easier too loose control on it, slip it, and make high voltage short :D I advice using medium one, with caution and common sense.
This makes my hands sweaty to watch.
100k already? Holy hell your channel is growing fast.
make a video on making a medium sized Tesla coil
thank u thank u very much Nate.
Thats awesome mate,,never know that cfl circuit works as plyback driver..now i know,,new subs here
Regards to all from Philippines

wow!!!!!!!!!!!! I was thinking about this idea and going to do it !!!! nice
A compact fluorescent bulb AND a flyback transformer from a kind of TV that hasn't been popular for 15 years.
What is the voltage on your primary coil;
Pretty sweet, man!
you must feed apl pin to get hight current
7:08 "it doesn't have enough current to kill you"
electroboom, where are you?
Ehh, voltage delivers it, but current is ultimate what kills, kind of? It’s really power so it can be viewed in so many ways, but ultimately the flow of electrons is what does it
Keystone Science Thanks for your answere! Yeah ur probably right since ur like really smart. I dont really know what im talking about so i’ll leave the job about electronics over to you, thanks again.
@@KeystoneScience as long as you don't have 60+ volts at high current, or more than 0.005 amperes at high voltage, you should be good.
now you should try connecting the high voltage wires from the flyback and connect it to he fluorescent tube
If you have a soldering iron you may as well make a ZVS driver with two IRFP260Ns
+infeazhar inc. yeah, I've made one with 250Ns, but I do want to make a 260N
Great video! Could you make a video about voltage spikes and how to prevent it? Would be helpful.
Brilliant fun!
Awesome video man!!!
can you put a few fluracent bulb circuit boards in series and increase the power
No, if you hook the output of one CFL to the mains input of another you will fry the other, most spectacularly. You can't use them in parallel either.

If you do go with a more powerful driver please make sure you know what you're doing and be careful.
very nice!
i think that we sould also join capacitor wiring because it also works well
pls help me the transformer in the bulbs ciruit it only had two wire connection can it be useful as step up transformer ?..how ?.
god nice this marx genarator this knekted
Have you considered immersing the cfl circuit & the flyback xmfr in mineral oil?Also you can add a 30kv or larger capacitor from the flyback xmfr output for larger sparks.

Using a high voltage transformer from a CRT TV, why not rig up plazma display inside the CRT so it can be seen jumping around all over inside the screen? It would be impressive yet safely contained.
A video about a >big< musical teslacoil would be great!!! :D
Will you make some video like this in the future?
Very good video and I like you
This would be great to power a TEA laser.
i wonder if you could put 2 of these in series or parallel to get double the voltage or current
Perfect, I've been wanting to make a Jacob's ladder for a while and I have 2 flybacks spare. Ps. Nice watch.... Casio CA53W.. . I also wear one. 👍
Ah, it does matter what AC lead goes where. I would advise to have the Live connect to the red wire and black to netural. Also use a polarity style plug, the bigger side (Left side) is Netural and the smaller (right side) is the live side.
and so I love Keystone Science
do you think an old computer monitor would have one of those transformers?
Anticonny would it just be smaller maybe?
Jake Waddoups hell goto a junk shop and buy the oldest biggest tube tv in the place it will have a huge transformer! ☺
Yes, but size doesn't really matter.
I never heard that one.
@@annelieseocallaghan801 exactly, it's not the size of the hammer, it's the nail you're swinging it at!
Scary Movie reference...
I have a few flybacks and I have noticed that on two of them the primaries are 0.5 ohm, not 1 ohm.
Amazing
per every cm of an arc there are 1000 volts and therefore for a 15,000 volt power supply you would need an arc 15 cm long
it's 1-3kv per mm
this is very clever!!
Maybe you can help but I have tried your configurations with the flyback transformer and I didn't get any arcs. Also when I took my multi meter to test the connection of the flyback for the large secondary the large the wire didn't beep with any of the pins so is my flyback broken or is there a secret I am missing
does the Bedini circuit really work
I tried at least five times to use the CFL circuit but for some reason, it wouldn't power the flyback transformer. Using a light ballast worked finally got it up and running.

could i use an usual transformer instead of a flyback-transformer? (really not in the mood to carry one of these old tvs home)
how can we connect this circuit to a bulb to make a plasma globe
Sir why we not use cfl out put frequency to make smps
Are older flybacks more powerfull?
Nice work.
I love the way you explain everything with their proper working science.

im pretty sure that the primary is the 1st and 3rd pins and the 2nd and 4th pins are the feedback
Hi Awsome video... Will this work on a 12v ignition coil
Can you make an mini van de graf generator that u can touch
So... I have to connect the flyback to the pins that are connected to the capacitor?
i have all ofthese things lol but im afraid to try it
BIG QUESTION !! did heconect that florcent to 120volt outlet?? ???
If i use a more powerful cfl bulb it will make bikker arcs?
Hi Keystone!

Sorry! Meant to leave the previous comment on your channel page! Love this video though! Thank you! Keep up the great work!
WARNING PEOPLE. The board removed from the lamp has capacitors that hold a high voltage even when disconnected from the mains.
Is this generator capable of powering fusion reactor?
nate what is the output of the cfl circuit alone
Maybe I missed it.. but what was the purpose of taking out the circuit from the bulb? What purpose does it serve in this exactly? Is it just to start with a higher voltage than mains?
It makes a square wave that makes constant changing magnetic fields through the primary coil which drive the secondary coil to high voltages
can you show me how to make a pure sine wave inverter?
that driver fry fast maybe you can provide us some upgrade to prolong that drivers life.
As a 12 years old kid I can conclude that high voltage can look like a child's play until you touch it lol.....
Ive found that an electronic 40 watt ballast works better, and is damn near indestructible. more arc length, etc
l make flyback from odd tv transformer driving it with 85w cfl but when l connected a capacitor across the primary the output voltage increases but suddenly the cfl blow, why did it happens so?
Great videos awesome education, Have you tried to make a home made metal detector?
can you explain what are the knobs for on the flyback?
Please what the name of this tranceformer i need to know the pins
Ok,...so,..how are the "arc" igniters that are used in the 'torpedo', or "salamander" type of heaters made?
The electrical arc, is what ignites the kerosene, diesel or propane,..& this arc, IS, "running" for as long as the heaters are being used.
How are the igniter modules constructed..so they CAN operate for so many..MANY, hours of use, "without" constantly "burning out??"
Are there any differences (like lower power/ voltage) between this high voltage supply and the one with the big ballast block?
can we make a air cooler using thermo - electric generator...................?
Why is my spark so small? Nothing like what yours is. Thanks, James
I did the same but continuous resistance to the problem of how to solve the problem, how to solve the problem until after the arc is up to 1-2 seconds
what's the output from the fluorescent circuit that you're connecting to?? like.. what's the voltage output that you're getting from it?
