Hey Guys! Join the Discord Chat! :D discord.gg/rvnbhNN

CRT "Can be shocked" LOL that's an understatement. As always EXCELLENT video !!!!

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

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.

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.

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

"and see which one it arks t-- Auw! okay..."

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

underrated channel

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

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.

This is the stuff I wanted to build as a kid. Thanks! Im gonna build this!

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.

Notification squad, Anyone else? :)

a DC to AC easy homemade inverter .. i like those

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.

Keystone, at one point in the future, we should consider a collaboration. Love your work. We specialize in HV up to 500kv.

you should make a intro to electronics series

شكرآ جزيلا على هذا الفيديو المفيد . تحياتي لك من تركيا.

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

Another fantastic video. Keep it up bro. Also, sick pen, haha.

This makes my hands sweaty to watch.

awesome! I've been waiting for something like this

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

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

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

WARNING PEOPLE. The board removed from the lamp has capacitors that hold a high voltage even when disconnected from the mains.

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).

This driver is preety good but it feels better to make your own zvs driver circuit

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

100k already? Holy hell your channel is growing fast.

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.

make a video on making a medium sized Tesla coil

Thanks for the video, I'm trying to do this by myself 😁🤘🏻

and so I love Keystone Science

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

Thats awesome mate,,never know that cfl circuit works as plyback driver..now i know,,new subs here Regards to all from Philippines

If you have a soldering iron you may as well make a ZVS driver with two IRFP260Ns

do you think an old computer monitor would have one of those transformers?

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

can you put a few fluracent bulb circuit boards in series and increase the power

Pretty sweet, man!

thank u thank u very much Nate.

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.

Awesome video man!!!

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.

Great video! Could you make a video about voltage spikes and how to prevent it? Would be helpful.

now you should try connecting the high voltage wires from the flyback and connect it to he fluorescent tube

wow!!!!!!!!!!!! I was thinking about this idea and going to do it !!!! nice

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. 👇😃

you must feed apl pin to get hight current

im definately going to send you something

Brilliant fun!

A video about a >big< musical teslacoil would be great!!! :D Will you make some video like this in the future?

god nice this marx genarator this knekted

What is the voltage on your primary coil;

very nice!

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?

thankyou

Amazing

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?

I have a few flybacks and I have noticed that on two of them the primaries are 0.5 ohm, not 1 ohm.

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.

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

Me and my faithful servant Igor we are struggling in wrong way to catch thunders and lightnings from the sky to revive that Frankenstein with no success as far.Tomorrow we will try new strategies and we are going for wire winding coils.

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?

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!

i think that we sould also join capacitor wiring because it also works well

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

Very good video and I like you

Can you make an mini van de graf generator that u can touch

does the Bedini circuit really work

This would be great to power a TEA laser.

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. 👍

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

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

this is very clever!!

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?

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

a paper letter? I didn't know people still mailed those with a postage stamp when email is almost instant and free.

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

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.

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

I find that hanging the mail in the same place where you do the experiments, is a serious fire hazard.

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

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

sir I have tried everything but my transformer is just giving very little just negligible sparks

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

7:08 "it doesn't have enough current to kill you" electroboom, where are you?

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??"

Ive found that an electronic 40 watt ballast works better, and is damn near indestructible. more arc length, etc

Why did you use a high voltage supply to make a high voltage supply, I don't get it, what happens if you just put 230v ac into the flyback primary?

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.

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

how can we connect this circuit to a bulb to make a plasma globe

Why is my spark so small? Nothing like what yours is. Thanks, James

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

Sir why we not use cfl out put frequency to make smps

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?
