Homemade Flyback Transformer Driver

[hardstyle905]

"high voltage OOT lead"?

must be canadian.

[Shroommduke]

cool sound but I keep waiting to hear a scream... ahhhhhhhhhhhhhh! ...nothing like a 45,000v shock to rattle your cage!

What's the pin-out on your transformer?

Why didn't you use one of the transistors from the monitor circuit board?

Do the dials on the flyback transformer do anything?

[HorizonDelta]

Nice...

[asdwjure]

can you use another transistor or it must be that one??

[rammsteinfreundsonne]

i have the same switch <3

[MikeAMDXP]

can you send me a wiring diagram?

[zenosxr]

Suction cups are ... stupid love it

[whiskeyify]

I repair tv's I was looking for a way to test a flyback I think this would work.

[TheVera0321]

cuales son las patitas que conectastes del flyback??

[Jhfgsjdcd]

You guys you need a multimeter to check for continuity ,. Or just make the circuit and then connect to all the different wires until walla you have a output just becareful because if you are even touching the insulation on HV and your hand is close to ground it will give a pretty nasty shock!

[RrahimStruja]

I use to play around with crt TV components when I was a kid and the first thing that i remembered when I saw this video was the smell that flyback transformer spike produces, does anyone know what is it?

Big "LIKE"

[Alex1M6]

@RrahimStruja Ozone. It has a metallic smell and taste and can give you headaches in large amounts.

[RrahimStruja]

@Alex1M6 Thanks Alex :)

[toyu17]

whats the output voltage?

[Scorpion9709]

@toyu17 around 5000-8000 volts

[guruji243]

I've built this with a 2n3055 to 12v source. Heard the transformer sing but no spark came out from the out wire to any pin.

Any help please?

Thanks

Thanks

[Landotter1]

Someone needs to learn how to solder and use perf board....

[sonnytiger]

does anyone know what the two wires coming out of the top are? they seem to be connected to a module on the side where there are a couple of knobs for adjustments, but they are not connected to the rest of the flyback, does anyone know?

[Landotter1]

@sonnytiger I'd have to check but those controls control brightness (G2 voltage) and the other, focus, so one will most likely go to the back of the tube (base) and the other will most likely go to the yoke. I'd have to double check though. It's been over 20 years since I repaired a TV. Electronic repair in the US is almost dead. I'm in aviation now, and have forgotten much... sorry

[45llamas]

good tutorial! but I do not understand English :( i from chile

[coolaidkiller101]

why,a 9 volt?

[drtarik33]

can you please give us a schematic for this circuit, I have all the parts, the Mosfet (eventhough not the same reference but will work), the flyback Transformer, the heat sink and the switch; all I need is the schematic.

I am attending to make an air purifier.

in this case, can I make my own transformer? let say, primary is 10 turns and the secondary is 2000 turns, means if the voltage is 30 volt, will become 6000V, but I think 6KV not enough for air ionizer, I need more voltage.

thank you.

[FlameSwordWielder]

@drtarik33 Schematic is at end of the video and if you want higher voltage you might have better luck trying the cheap and easy 555+MOSFET flyback driver, google 555 flyback driver.

[drtarik33]

@FlameSwordWielder

OH yes yes, I am so stupid, it's my fault, I didnt see the end, I just left the video after I saw "thanks for watching"....!!

ha ha ha, I am so sorry for that.

by the way, I dont have a 555 IC..:)

I will send you some video about what I have and please help me to find out what pin I use for a feedback coil.

thank you

[FlameSwordWielder]

@drtarik33 You can identify the two feedback coil pins easily by measuring resistance between your pins using a multimeter, when you get a fairly low resistance you found a coil, feedback has little lower resistance than primary but i heard they can be swapped, i can`t tell the pins just by looking at the flyback.

[ExplosiveAnyThing]

if you want more power try to add a capacitor at the primary windings and wind your own primary cause the primary at the flyback is designed for 300 volts not 9.

[tyreza79]

I HAVE ON FROM A CRT TV? I NEED TO KNOW HOW TO CONNECT IT !!!!! BECAUSE IT HAS 10 CONNECTIONS DOWN BELOW? ARE YOU USING ONLY 2 OF EM § I WOULD LOVE DETAILS§ AND I WILL MAKE MY OWN RESEARSH . BUT I WAIT FOR YOU ANSWER TOO §§

THANK YOU :)

[playcss1992]

@tyreza79 dude go to my channel and look my ZVS-Flyback video ;) if u have questions feel free to ask me, but this driver is not good...

[sonnytiger]

@tyreza79 STOP YELLING AND MAYBE SOMEONE WILL ANSWER YOUR QUESTION!

[chilidress]

ps the Hz of the generator varies from 1-200Hz

[chilidress]

can i use a bike generator which is 6v 3w 0.5a to feed a flyback transformer? if yes is there a site or schematic for help? answer ASAP

[kmncztms]

If you connect 2 flyback drivers with 2 flyback transformers in series, would it create twice as big sparks as with 1?

[ihos501]

actually Canadian, lol i just knew it

[gangster010101]

It`s working on 9V but not on 12V. WHY?

[bobdole10156]

what kind of heat sink

[MrStemkilla]

@gamer1337omg no it would just give you a lets not do that agen feeling

[xXLoVeRandHaTeRXx]

do you have a diagram for this or could you make a tutorial?

[njipods]

you can definatly tell you have grown up your other vids are wank lol

[acdcfreak5745]

woah

[carlos10las]

can i use a 14 awg stranded wire besides a magnet wire?

[Secretlyastonishing]

He says hawt not hot.....I love how he says it! :D Haha it so cute

[minninulsi]

Sort of want

[abzosairis]

@LiquidChem All of the transformer is an inductor. The primary is an inductor and the secondary coil is an inductor. The primary and secondary coil are held close to each other in such away that the two coils(inductors) generate a so called mutual inductance. If one of the coils are being supplied with a voltage or current source it will induce voltage to the other coil. Yet each coil should have known inductance to calculate a desired output voltage. Unless we will consider an ideal transformer

[petermines]

@abzosairis Dont forget to mention that induction only occurs providing it is an AC or otherwise pulsed supply.

[23brandonsch]

do think they have it a radio shack mje 13009

[Ozzyzzo76]

The PICTURE TUBE is Bad, WANK WANK!!!

[ChuKoNu1]

@Ozzyzzo76 ..the fuck?

[Masamuneblade7]

@ChuKoNu1 my guess is his picture tube broke, and he smashed his tv to get his parts

[mateus39318]

@ChuKoNu1 I liked the video, your driver works very well with a 9 volt battery I did the same circuit with npn MJE13007A with a flyback DC and worked well.

Try a driver with a fluorescent lamp ballast for a 36 w​bulb, it works very well see in my videos.

[LUVB6CPPgmodcsscoder]

@Ozzyzzo76 LOL

[bleachworthy]

"I cut it off, cause suction cups are..... stupid." priceless...

[RRdigy]

I have a problem. I think that i made the circuit for my flyback transformer right but theres somethin wrong-It gives out only 19 volts when i use a 9 volt battery! there are sparks but they are only about half a milimeter long. Why it doesn't make normal sparks and big volts?

[YU1SRT]

can this staf kill you?



[ConnorXV]

will i destroy my flyback if i stuck 2,3 or 4, 9v batteries into the circuit?

[bleachworthy]

@ConnorXV I'm sure you can put 12v or better to the primary, that's what I'm working with and it's fine

[Alex1M6]

@ConnorXV I wouldn't go any higher than 24v personally.

[khqola]

suction cup i stupid HAHA XD

[footsy75g]

thanks this vid helped me alot

[a380rockerfan]

SUCTION CUPS ARE NOT STUPID!

[plecebomc]

im working on a Jacobs ladder and i robbed my monitor of its flyback transformer. how did you figure your pin outs on the monitor flyback? Mines still soldered to the board but i was wondering how you found it. i would figure you did a search for a data sheet on the part or traced the pins. video helped me a lot thank you

[reviathon360]

@plecebomc

I don't think he did. I'm watching his video and he said "3 turns primary." So it looks like he made it himself. 

[a380rockerfan]

@plecebomc search "how to identify pinout of flybacks" on the web.

[munsif55]

that's great of you, and through this video we knew how crt monitor works and how electron beam is generated inside, but presenter has done a marvellous job with battery. i am currently researching on flyback transformer, so my first aim is to check g1 and G2 pin voltage with monitor in switch on mode, can somebody tell, how to touch multimeter's probe pins on G! and G@ pins of crt's circuit board fixed behind picture tube. kindly send your explaination to munsif_44@yahoo.co.uk

[aleksei13r]

hola esta muy bueno tu video ,podrias decirme con un diagrama como lo hicistes

estaria muy agradecido

[listentotiesto]

i like how its all wires out shows how simple this circuit is coming from some one who just starting reading up on this kind of stuff was begining to feel discouraged until i came across this

[Arjoonmoal]

pretty weak. the mosfet version draws more current and also if you use 555 timer. you can adjust the frequency to get a better results

[nikHILO2]

nice......it would be better if you would put everything in order!

[ChuKoNu1]

@nikHILO2 ?

[nikHILO2]

@ChuKoNu1 ummmm.like everything is mixed up ........

[loco15912]

@ChuKoNu1 Explain how is everything build, wich attachments goes together(the circuit)

[nelsonmachupa]

"but i cut that off... cuz suction cups are stupid..." lmao

[Alex1M6]

@Zach334455 Use a multimeter to read the resistance on the various pins on the bottom of the flyback.

[marcheseDS]

Any measure of power, primary current, frequency of oscillation? Without any capacitor I think it is oscillating at very high frequency, limiting the the power: I would like to know instead of suppose... :)

[StopMotionMind]

1:36

"It had a suction cup attached to it, but I cut it off because...

-_-

suction cups are stupid"

Hilarious

[crusader84941]

2:35 lol it sounds like a guitar solo

[thecatofwisdom]

lol cuz... suction cups are stupid...

[a0r0d0i0t]

Can that thing kill you

[hardstyle905]

@a0r0d0i0t With a small 9V battery like the one in the video - no.

With more power it could cause injury, burnings etc. perhaps even muscle twitching. It also greatly depends how you touch it. The worst way to do it would be touching the electrodes with both hands so that the current flows through your heart... I don't recommend trying it haha.

I have a "touching video" on my channel but it was done with low power like this.

[maleshmawa2007]

nice driver there buddy, i kinda need help wit mine, am using 22ohms 1 Watt & 220ohms 5Watt and 2N3055 NPN transistor, similar circuit as yours, I tried to use 12v from PC power supply, sometimes it doesnt run and also I dont hear the high pitch from the transformer, WORSE no sparks, Can u plz help?

[marcheseDS]

@maleshmawa2007 A few things to check: try a lower voltage or a different resistor ratio (270,22) to keep the base to emitter voltage around 1 volt. next I would check the feedback, maybe you reversed the connection so it pulses out of phase. third you could try a different transistor or try adding a pF capacitor between base and emitter. Oscillators can be tricky

[Alex1M6]

@maleshmawa2007 Switch the primary coil polarity.

[remzi133]

can i also use a 270 ohms and a 27 ohms resistor or not?

(I can't test it because i don't have a flyback driver yet.)

[snyperbob]

Hello, can you tell me the watt rating of the resistors you used? Is the 220 ohm resistor a 5 watt and the 22 ohm a 1 watt? Thanks

[ideeman1994]

In the moderns flybacks (yours is one of those), there is a built-in rectifier diode on the high voltage output... So this transformer converts AC (the circuits sends a pulse of about 14kHz) to DC...

I think there is also something you can do to increase the voltage... Try switching the polarity of your primary (the one you soldered directly to the pins, not the one you winded). Normally, with this kind of circuit, you should be able to have an output of around 30kV...

[FailedSquare]

because- suction cups are stupid. lol

careful pulling apart any CRTs that flyback circuit can kill you

[coilsinamotor]

i did this with the mje 13003 it exploaded in 2 seconds :)

[defectindustrial]

Nice work. For more fun get yourself an oil burner ignition transformer. The primary is 120VAC and the HV secondary is around 10KV (RMS) at 25mA (yes, that's 10,000 Volts). Google it, you'll like it.

[zhmapper]

"I cut that off because, well, suction cups are stupid."

:D

[MrWanderson12345]

este sistema , que pode ser conectada a uma lâmpada de luz é um plasma

grato

[ronwire182]

but how do i know where the feedback and primary coil of the transformer is

[mapukmapuk]

battery is DC and the transformer what? if transformer is AC, how you make from DC to AC?

[ChuKoNu1]

@mapukmapuk The transformer converts the low voltage - higher amp DC, to higher voltage - lower amp AC.

[mapukmapuk]

@ChuKoNu1 tnx

[Akrurz]

@ChuKoNu1 Actually, Your driver converts low voltage DC to a Sawtooth pulse ( /I/I/I/I/I/I ), which the flyback then amplifies the voltage of.. feeding pure dc to the transformer will have no effect :p.

[bucketheadisamaster]

@ChuKoNu1 the transistor does it

[ConnorXV]

@ChuKoNu1 well the transistor switches the circuit and effectively makes it AC for the Transformer to convert into the high voltage.

[TSorovanMHael]

@ChuKoNu1

Transformers won't work at all with DC due to Faraday's law.

[ChuKoNu1]

@TSorovanMHael True, but DC Batteries will work with this circuit due to the transistor quickly pulsating the DC in the primary coil, which allows this transformer to operate using DC.

[LiquidChem]

@TSorovanMHael but flybacks arent really xformers though.. theyre actually inductors

[0BostonGeorge0]

@ChuKoNu1 Dosent theese flyback models have a build in rectifier, so the output is dc?

[ChuKoNu1]

@0BostonGeorge0 some of the newer model flybacks have a rectified output. Mine doesn't.

[mapukmapuk]

@mapukmapuk woa lol tnx

[marcheseDS]

@mapukmapuk This circuit is a self oscillator, when connected to battery the current flows in the primary coil and induces a current inthe secondary and in the feedback coils (at very different voltages due to ratio of turns in each). The current in the feedback coil opens for a moment the transistor, thus cutting the primary current. The feedback itself is then stopped and the cicle starts over again. The frequency of this cycle is very high and in this simple circuit not easy to change

[mapukmapuk]

@marcheseDS ow tnx for help

[Alex1M6]

@mapukmapuk The transistor oscillates the DC current via the feedback coil on the primary side.

[mapukmapuk]

@Alex1M6 o you mean this circuit is DC current? and the transformer out put DC too? , tnx

[Alex1M6]

@mapukmapuk Yes it is DC.

A transformer only induces a current when there is a change in magnetic field, which AC current will do on its own. To get this to work with DC you need to "pulse" the current so that the magnetic field created in the transformer (or fly-back transformer in this case) is constantly being created and destroyed in continuous cycles, and the transistor acts as a small switch controlled by the feedback coil that turns the circuit on and off at high speeds. Hope I helped!

[mapukmapuk]

@Alex1M6 you very helped me tnx man!

[Digadogup]

@mapukmapuk the transistor turns the battery on and off a a very high frequency making a magnet with the transformer that has a high frequency in other words

energy (dc ) -> transistor (dc) -> transformer (fist winding dc ) second winding (ac)

[Chewylu103]

@mapukmapuk Something in the circuit must make and break the electricity to the transformer, i see what your saying a wire wound transformer cant sustain a dc field, but if you flicked it over and over it would create a field across the primary coil that would for a split second induce current into the secondary coil making the transformer work on dc.

[mapukmapuk]

@Chewylu103 tnx man

[astriknon]

@mapukmapuk The function of the MOFSET is to switch the voltage and occillate it at a high frequency which powers the transformer.

[pieznice29]

I would recommend you use a better power source than a 9v battery, they can only supply very little amounts of current. I get great results from a 12v 7ah SLA battery.

[natna25]

i would use 20 or 18 volts if you want a longer arc but then you would need to change the whole circuit and it all depends on what the transistor can take but great job

[DigiDavidex]

facci un taser ;)

[kanfagun]

hi chukonu thanks for your reply but i couldnt make without measurement or type of component and keep moving best regards

[kanfagun]

hi I m interested on your flyback would you PW me your schematics design please thanks

[ChuKoNu1]

@kanfagun The schematic is at the end of the video, just like it says in the description.

[kanfagun]

@ChuKoNu1 hi chukonu thanks for your reply but i couldnt make it without measurement or type of all component and keep moving best regards

[0903390901]

photos ? photo HV transformator connectors?

[0903390901]

EASY :)

[cody2o0]

Wooh 101st LIKE!!

[ronwire182]

Can u pls post the circuit diagram

[ChuKoNu1]

@ronwire182 Durrr

[ronwire182]

@ChuKoNu1 sorry i dident watch the whole video my bad

[joblessalex]

Lol I cooked the 220ohm resistor after 5 seconds of it being on running 12vdc! Any fix?

[08Kutt]

please see my video, I made a flyback driver like yours, and i used a 12 battery, thanks to post this video!

[renshawhu]

That looks alsome. I've seen this project used for plasma tweeters, using a flyback transformer. I wonder if there's a way to replace standard speakers period. It would save a lot of money.

[rroge5]

how do you know which wires on the flyback transformer to connect ?

[coilsinamotor]

one qoustion does u tube pay u if you get a cirtin amout of subbies or how is the project payed by us?? thanx

[Bomberboy92]

Hello ChuKoN1,

awesome video and very simple and easy design, i was surprised it works!

could you be so kind as to put up a video detailing which connections go to which pin on the transformer itself? it would be a great help not only to me but all the other HV wannabes out there too! thanks...

[king4allstars]

It works!

[king4allstars]

Verry good work! it works!

[Srabbel]

think the secondary is inside the DST... both used coils/windings are primary... one is the power-winding, the other one a kind of signal-winding to drive the transistor...

[andymouse123]

you dont need to wind your own primary with a bit of trial and a lot of error you will find a coil you can use

my fly-back set up is basically the same...a potential divider and a high power transistor and i have ratio of about 1000:1 that is 1v in 1000v out it works well at 30 volts the transistor is a 2n3055 on a heat sink with a small 12v fan and i get 30 Kv the transistor doesn't even get hot producing 45mm sparks continuously

[bonecrime]

9V batteries are weak. Try using a better power supply, like a car battery or some form of DC adapter or lab supply capable of delivering a few amps. Watch my vids if you want to see what happens if you do! :)

[hardstyle905]

@bonecrime a car battery will prolly burn this small circuit tho lol

the "zvs" circuit is better for that...due to 2 transistors

[scuffieduffie]

whare did you take the wores from that you connect to the transformer???

[gacek999]

I made the same circuit and it works good. I used C5440 transistor and HR46203 (FQB-17A001) flyback transformer, both found in Samsung monitor.

[vitorix24]

What is your resistor? the Reference?

[asdfgghjklpoiuytr]

chukonu1 i want to make your circuit but i think to use a S2055AF transistor instead of your.Thats will be ok?Also i want to know if with this circuit i can power supply a small tesla coil...(i think dont make my own primary coil but use the transformer's one)..I looking forward for you reply!I forgot to say that your circuit is best one and simple i have ever seen!

[asdfgghjklpoiuytr]

chukonu1 i want to make your circuit but i think to use a S2055AF transistor instead of your.Thats will be ok?Also i want to know if with this circuit i can power supply a small tesla coil...(i think dont make my own primary coil but use the transformer's one)..I looking forward for you reply!I forgot to say that your circuit is best one and simple i have ever seen!

[deepcut71]

lovely little lightning :)

how would you ensure that the output was at 60 hertz ?

[codynynex]

i want one for test on my brother ahaha..!! Ty!... Love this.>! :P

[vitorix24]

if you tuch what happen you? its high voltage, but the "A" its very low.

[renekenshin6573]

Hmm i suppose i'll try making one during my spare time. I have an old flyback salvaged from an old crt monitor lol. Anyways how did you trace the secondary? The secondary based on my understanding is the output anode cap and the other one i don't know where or which pin on the bottom?

[renekenshin6573]

In short that circuit is called an inverter. If you like electric arcs better make a tesla coil, its much prettier but works with higher supply voltages and not for newbies :D

[ChuKoNu1]

@renekenshin6573 Yeah I suppose you could call it an inverter, however it is not one in the practical sense. It is easier to just call it a high voltage transformer.

[djrobotfreak]

Which pins do you have connected on the flyback?

[Chicagokilla17]

theres 2 pins on the fly back that are right next to each other but far apart those are your positive and negative terminals

[08Kutt]

Man, I did the same thing, but I Can do any arc!!!! please help me!

[fireitup9]

can u give me a schematic of this please because Google just doesn't help

[fireitup9]

Ive got a single N channel 60v power MOSFET would that work in this project

[metaltomato100]

i tried this with a 2n3055 but i cant get any sparks.. i dont no if i wired up the coils corect..som1 please tell me a good way of identifying the coils and tips on how to make this thing work

[metaltomato100]

i cant do mine... i have tryed this with a 2n3055 but no sparks no nuthin i really need help.. if som1 could help me identifie the piouts and tips on how to make this work..that would be great...great video

[metaltomato100]

i cant do mine... i have tryed this with a 2n3055 but no sparks no nuthin i really need help.. if som1 could help me identifie the piouts and tips on how to make this work..that would be great...great video

[mrtwisty]

that transistor is in larger CFLs. i just happen to break one and looked at the transistor.

[pixuma]

so what exactly is the HV output arcing to?

[uN1Qu3DZ]

Btw you should instruct people not to touch the flyback pins even after power is removed and the high voltage lead is discharged.

There are other voltages that remain in the flyback. They are not dangerous but they can deliver a nasty shock to the unsuspecting.

[gbmilan]

@ 3:01 you can see the corona, very impressive keep up the good work!

[ubuntupokemoninc]

why do you need the driver i just made a secondary and and hooked it to 240vac with a couple of huge resistors, and got it calculated at 35vk

[GearzVoNKod3]

Don't have 240 vac here, and I don't trust running mains voltage directly into the thing in the case that it shorts out or that I incorrectly insulate the wires.
