Thank you so much! This is way easier than building a driver circuit myself

every time i learn something new . Happy subscriber

I did this with a flyback transformer from a 5 inch CRT. Worked perfectly!

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.

Your videos are great young man keep it up. Been tinkering my whole life. ☺

awesome! I've been waiting for something like this

I am lousy at building flyback drivers. This looks simple and handy enough for just testing bulbs and farting around. Thank you, Dr Keystone!

Really amazing technique!!! I liked it very much!!!

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.

Wow this is pretty cool and it's pretty easy too!

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?

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.

You are now the official High Voltage guy.......Keep it up......

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.

Hi Awsome video... Will this work on a 12v ignition coil

thank u thank u very much Nate.

were do you get your crt tv? i had a fly back but i broke it. also can you get a satilite dish and make an fm transmitter and try and pick it up with your fm reciver

Great video. I've done this project and it worked out well. But the arks are very small, they do not even get to stretch 1 centimeter and the datasheet of my converter says that this produces 26 KV. Could it be because my fluorescent light bulb is small? If you have any idea what this could be, please tell me.

Pretty sweet, man!

Are there any differences (like lower power/ voltage) between this high voltage supply and the one with the big ballast block?

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.

Very interesting video! Can I do the same thing with 230v input(to the bulb circuit)? or will that burn the coil?

thanks man, i'm from India as well!....also,i was wondering if there was a way to find the primary of the transformer without a multimeter, as mine is showing a resistance of 7 Ohms when i'm touching the leads to themselves(cant trust it)

Brilliant fun!

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

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. 👍

very nice!

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.

This is an idea I must try - thanks for your comment/suggestion!

this is very clever!!

i wonder if you could put 2 of these in series or parallel to get double the voltage or current

you should make a intro to electronics series

Can this flyback be converted to an ignition coil of a car or a motorcycle cuz if it can burn a paper maybe it can also burn a gasolin fuel in the combustion chamber of an engine .

could i use an usual transformer instead of a flyback-transformer? (really not in the mood to carry one of these old tvs home)

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?

@jjnuni7811

im pretty sure that the primary is the 1st and 3rd pins and the 2nd and 4th pins are the feedback

nice arcing the one you achieved, mine turned out shorter using a 30 watt ballast and a flyback transformer found in a 20 something inch CRT. Why is it that when adding a capacitor between both primaries in the flyback I got longer arcs but the cfl circuit died as soon as I stretched the arc far enough to leave the circuit open?

CFLs ballasts have a built-in self destruct for when the tube burns out, killing the fragile components in the circuit.

i have all ofthese things lol but im afraid to try it BIG QUESTION !! did heconect that florcent to 120volt outlet?? ???

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.

Excuse me sir!!! I wanna discuss you on a topic related to a flyback and cfl. I wanna know about the CFL how much watt CFL is required to operate A flyback. I am in trouble. Please reply soon!!!

This makes my hands sweaty to watch.

Great video! how about showing every one how to build a bug zapper!

does the Bedini circuit really work

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. 👇😃

pls help me the transformer in the bulbs ciruit it only had two wire connection can it be useful as step up transformer ?..how ?.

can you explain what are the knobs for on the flyback?

If i use a more powerful cfl bulb it will make bikker arcs?

Very good video and I like you

The project is nice I was seeking if you could come up with a video showing how a joule thief circuit works🎉

Have you run this setup for any length of time? I was wondering if anything got excessively hot. I always wanted to make a Jacob's ladder but would like to run it for a reasonable length of time like 15 minute stretches of time. Please advise. Thank you. I just discovered you channel.

+Erick Eagle yes, you can make a trimmer capacitor, try getting 2 plastic cups and putting tinfoil halfway around each, attach wires and place one cup inside the other, as you turn the cup so that the tinfoil becomes more or less overlapping it will change the capacitance! You could also just use a set capacitance value and calculate the frequency it will broadcast at from the formula I showed! Hope this helped ! :D

Great videos awesome education, Have you tried to make a home made metal detector?

A compact fluorescent bulb AND a flyback transformer from a kind of TV that hasn't been popular for 15 years.

does it work with voltage multiplier?

Hi Keystone Science, I want to build one of these and apply it to make an outdoor rat trap. Could I use a 12 volt battery as the power source? TIA

Would this work with a 4 pin plasma ball flyback ?

As a 12 years old kid I can conclude that high voltage can look like a child's play until you touch it lol.....

Could you reconnect this to the tv and how long willl it last

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!

Sorry! Meant to leave the previous comment on your channel page! Love this video though! Thank you! Keep up the great work!

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).

Sir how much voltage you give to flyback?

thankyou

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.

hiii is is possible to connect a car ignition coil instead of this flyback trf,bcoz i got a good one with four high voltage terminal coming out hehe its from ford focus. I really appreciate and this is the fastest way to make a tesla coil....great.

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?

Ack! Too much! The first 13W ballast only worked VERY weakly once or twice for an instant. The second ballast was 14W (woopty doo) and it instantly start humming and throwing 3cm pink and purple arcs. I backed the wires further apart and at 4cm it stops the arc but continues with both tips creating angry corona fans. Backed it to 6cm and still corona hiss fanning out and angry hum. I wanted this thing for a few KV. I can go fire up the CO2 laser power supply for this angry stuff. Any ideas on the quickest way to tone it down? There is corona even coming off the bottom of the flyback.

Could you use a ballast from fluorescent tube light fixture

So... I have to connect the flyback to the pins that are connected to the capacitor?

@FredtheDorfDorfman1985

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.

Does it have to be a fly back transformer or can it be a step up transformer

@edwardsunnyboy

If it was just a regular step up transformer: A. You wouldnt even need the driver, just put in an AC current B. If it was a high voltage transformer (such as that of ignition coils, microwave transformers, or neon sign transformers) then it should work. However, if your transformer is not one of these, than you should get nowhere near the output voltage of the one shown in the video.

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?

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
