Super flyback

[shashair]

Amazing video! What's the amperage?

You didn't want your mother to know you were playing with high voltage, right?

That's why you kept the tv on :D

[CoolDudeClem]

I wish I could find some flybacks that give me these kind of arcs, I've experimented with all kinds of different flybacks, transistors and number of turns on the primary, I usually get a purple arc about an inch and a half long and a hot primary (need to get some thicker wire), still got a few ideas to try out tho.

[ExplosiveAnyThing]

This is HV AC or DC??

[CoolDudeClem]

@ExplosiveAnyThing Flybacks usually are DC, so i'm pretty sure that is DC.

[ExplosiveAnyThing]

@CoolDudeClem I saw the schematic and it's DC. Also I can get really big arcs from a small flyback using zvs driver and if you decrease your number of turns(one up one down) you probably draw bigger arcs because of the increasement of frequency.And what type of driver you use (555,3055,ZVS,push pull or what)?

[JUJO2532]

Este esta mas facil de hacer y sale mas barato armarlo buscar en proyectos ---> jjforum.webuda.com

[PyroCube]

I`ve never seen anything like this from a flyback transformer!

Good job!

[LanceCampeau]

Man... what planet did you come from? your videos are awesome fun stuff to watch... play safe!

[igor999gt]

how can a made this driver?

[a380rockerfan]

how the heck did you get HUGE arcs? i have a mini flyback from a small TV, i know, but how can I get the most power out of it? i really don't want to make something so sophisticated that it would make me and my parents pay 100,000,000 dollars or what, but please. reply. i will get a bigger flyback thou. :)

[jmartis2]

@muraturile I didn't know, but most likely it's less than 100kV- probably around 70 in this video.

[Nanovirus5995]

@muraturile Every centimetre is (+/- 5%) 1 thousand volts.. For example a spark that draws 45mm will be 4.5kV (kilo volt) however you notice that the ark is curved and takes a non linear path. So this would imply that the ark is actually stronger that the length between it and the cathode.

[zker666]

Go ozone!

[pokemonaca]

stick your finger in there lol

[zker666]

mmmm i can smell the ozone from here! Will this driver be finished?

[jmartis2]

@zker666 It is finished, see my video "Super flyback driver final version"

[mtilley3]

would it hurt if you put your tongue in between the two ends:P o.O

[randommezos]

@mtilley3 um no duh

[OnnomonnomonnO]

tak to uz je jaka fajnotaaaaaaa

[sparkie21]

This is amazing flyback setup! Well done!

[TheError404]

plz can you give me schematic bcuz my flyback can genaerate only 3 cm arcs

[jmartis2]

see my vid super flyback driver final version, there is a schematic too.

if you want a simpler but not so sophisticated circuit, send me a PM

[mapukmapuk]

@TheError404 my flyback dont generate any thing! i need help, i saw video the driver it from CFL compact fluorosent lamp, CFL has in built electronic plate and to all peope it work but not for me, :-( , pliz someone i need help too but i need something like electronic plate not to build myself i suck in this

[TheError404]

@mapukmapuk You can search Google 2n3055 driver, it's simple and not very dangerous (i touched output, it hurted :D )

[mapukmapuk]

@TheError404 lol? hh ok ill find this transistor or what this, tnx

[myman31sbob]

AWSOME

[lokeycmos]

i seem to have a problem with the IC burning out on me. ive been thru 3 of them already. any thoughts or ideas of what i can do to prevent this?

[radicalman66]

How do you wire this flyback? Do you have a schematic?

[fantasma20400]

para probar el flyback se saca del circuito o tambien puede ser probado dentro del circuito pero nada mas hay que saca el transistor de barrido horizontal para no dañarlo con la punta del multimetro en continuidad en la pata colector del transistor y con la otra punta hacia al flyback hasta que de continuidad obtendras el +b y lo mismo se repite para localizar el oscilador con respecto a + b una punta en +b y la otra en una pata de fly hasta que de continuidad y estara listo para ser probado

[lokeycmos]

i must commend you jmartis! i finished putting this together tonite and it is AMAZING. I got some serious output. i cant wait to try your newer finalized version.

[438426x1]

wats corona?

[codemsan]

its basically ionization of the air before theres a short enough gap for full breakdown of the air to strike an arc

[nyditch]

err... by "vary it" I meant the length of the arc. You know what I mean.

[jmartis2]

Of course that the voltage drop is way lower with a short arc. When I say that a power supply generates xx volts, it's meant as a open circuit voltage.

[nyditch]

It would be difficult to estimate the voltage considering the condition of the air can vary it drastically. Either way, I don't think the output voltage matters as much as the result, which I'll have to agree is very nice.

[ftynmik]

What frequency?

[jmartis2]

This is DC, but the driver runs at 21KHz

[ftynmik]

High voltage! no coment! =)

[thuzjak3]

i am making one with 555 timer and irfz44n mosfet,but it isn't strong enough!

i don't have oscilloscope to measure the frequency to make it resonate....but when i connect it to a empty coca cola can,it rises the paper in the air!!i will make a clip about it!

[miwgub]

Ok. Thanks.

[miwgub]

Do you have any schema to this circuit?

What is a driver?

[jmartis2]

hi, this is the schematic I used for this driver volny(dot)cz/jmartis/superflyb­ackdriver.png

(replace "(dot)" with "." )

[jmartis2]

and remove the space in the URL... stupid youtube

[afdhalatifftan92]

Lawlz!! Stoopid Yootoobe!!

[jerronimo3000]

it doesnt work! is there another place????

[miwgub]

Yes, I used "." earliest. Thank.

How is the type of transformer. How is he to mark?

Do you have oscylogram from primary turns?

[jmartis2]

The transformer is a DC "flyback" transformer (DST, diode split transformer) from a Sony TV. It is the type potted in some black resin with integrated rectifier.

[miwgub]

Thank you for all answers.

I am from poland and I can't english language so I want to can.

[260830107]

does a ZVS driver increase the output current and lowers the output voltage?

[jmartis2]

basically, yes

[Mosfet510]

Holy sh*t! Awesome arc's of that flyback!! At one point it looked like a propane torch flame lol. Nice one

[samssoftwareuser]

ooh sqweaky and smelly!

[OnnomonnomonnO]

crazy sparcs man :D you're not normal :D i like it xD good luck:D

[Gintaras]

is ozone from flyback HV sparks dangerous? after I build my flyback driver my whole room smells like ozone!!

[jmartis2]

I know that, if it's for a short while I don't see a problem. It only becomes a problem when your throat gets irritated, and this is a sign that you should stop, but it shouldn't cause much harm.

[djdoug99]

i love the smell of ozone when I draw arcs.

[jmartis2]

me too :)

[achahid55]

hi jmartis2 cool video well done

one question: can 12V/ 3A supply drive the circuit?

thx

[jmartis2]

thanks,

yes it can but probably with poor results.

My circuit draws about 6 amps from 32V (~200W)

[rada1224]

that purple thing , it so cool! what is it ?

[jmartis2]

its Corona discharge

[rada1224]

what happen if you touch it?

[jmartis2]

it will arc to you from the HV output and shock you, or if youre insulated from the ground, it will charge you with static electricity.

[rada1224]

does corona discharge only appear in flybacks?

[jmartis2]

no, it appears everywhere around high voltage conductors, if the voltage is high enough (approx. >10kV) and the voltage gradient is high enough.

[DonaticX]

call it ozonomat ! :D

nice one

[miwgub]

Unbelievably and beautifull.

Great project.

Electricion from Poland

[zezimashock]

in your schematic the irfp250 are parallel why?

and how can you power it with more powwer?

[jmartis2]

1) because this way they don't get warm. It will run with just one.

2) I don't recommend using more power as this can destroy your transformer...

[zezimashock]

i allready destroyed one :(

i started to smoke and smell funny,

then it caught flames :(

now i have to find a new one :(

[jmartis2]

Hi,

thanks, yes it is possible to audiomod this driver, but the quality won't be great. I have another circuit for audio arcs which uses Frequency Modulation and produces very clean sound :) (you can see my vid "More singing sparks" also note it sounds much better in real life).

[RotogenRay]

In any case, this is the most impressively driven flyback I think anyone has seen... a lot of current and a tremendous voltage coming from that little transformer!

I'm very interested, as I think all of us are, in seeing a schematic of how this was accomplished.

And my apologies about any voltage arguments i've caused, I just think that, most of the time, we like to think our devices put out more voltage than they really do... But I'm guilty of this as well

Schematic pl0x?

[jmartis2]

Thanks,

I have already obtained considerably higher powers and voltages from the transformer (arcs firing at 12-14cm, up to 300 Watts with the transistor just warm, it was also adapted to run on an IGBT).

However I have some problems with pulse current limiting which must be implemented at these powers otherwise something can go "bang" with short arcs. I hope to get this resolved soon.

I'll post a schematic when I get home.

[RotogenRay]

Brilliant!

[jmartis2]

Ok, here is the "basic" schematic:

volny(dot)cz/jmartis/superflyb­ackdriver.png

35V is the absolute maximum for supply voltage, I'd rather use 32V. Set running frequency at 20-21kHz. Duty cycle varies power.

[jmartis2]

Please remove the space in the url, intelligent youtube comment system probably thought it would be better with it.

[anon32016]

Can you post an coupling scematic on that? That would be great!

[cheatman41]

its not a flyback its a negative ion genarator

[jmartis2]

if something, then positive ion generator. But the transformer is commonly referred as "flyback" transformer.

[RotogenRay]

Also horizontal output transformer... if you were born in the 50's, which, I wasn't

[anon32016]

That was great! Uber voltage 4 teh win!

Look at those dim corona discharges... ^^

[danyk666]

já sem dělal taky výboje 10cm z IHVT, ale po minutě se mi šlehlo :)

[jmartis2]

jj, ale tohle je SUPER EXTRA OWNformer :D je to jinej typ než ty normální, z TV Sony Trinitron a má ještě na výstupu takovej "výčnělek" (předpokládám že tam sou hrubě předimenzovaný VN diody)

[RotogenRay]

God you people can't estimate voltage for shit

I'll give it 30, maybe 40kV.

[jmartis2]

Well you are right that its not 100kV, I always put a "label" on my vids based on the 1kV/mm rule. I estimate the voltage here in the 50-60kV range, its when the voltages get very high (hundreds of kV), the discharge path starts to grow quickly.

Lately I was getting 14cm sparks from the flyback between 2 nails, that may have been some 70-80kV.

[RotogenRay]

even 1kv per MM seems misleading. Thats taking it as peak voltage, I've had a small spark gap fire at just a couple hundred volts, it really depends a LOT on the geometry of the electrodes, and its a good rule to take the estimated voltage and divide it out to the rms from a peak value.

Oil insulation won't stand up to more than 50kV, especially unloaded. I burnt out 2 ignition coils when I was getting like 5 inch sparks between (now THATS what I call high voltage)

[zezimashock]

how much volts?

i mean in put :P

[jmartis2]

input is 35 volts into 10 turn primary and resonant driver

[zezimashock]

and amps?

[jmartis2]

I think around 5 to 7 amps

[kalebman5000]

that is definatly at least 100kv cuz the arcs start at like 2.5 inches (higher volts=were the arc starts, higher amps=were they stretch too)

oh and i almost bought a scope like that on ebay

[RotogenRay]

Since when was 100kV a breakdown of 2.5 inches?

I have neon sign transformers (15kV) that will almost do that.

[kalebman5000]

dude i meant that they are starting at 2.5 inches

[RotogenRay]

I'm not arguing with you on the distance- its obvious the spacing of the gap- but your voltage estimation couldn't be farther from reality.

[kalebman5000]

i was just trying to complement the guy on his flyback dude i wasnt trying to start an argument and all i meant was that the arcs are starting at a very spaced out distance so it must be a very high voltage, i may have been wrong on the estimate of voltage but i was just trying to say that the voltage is very high. i appreciate the correction but you didnt have to come off so rudely.

and again i didnt say the breakdown was 2.5 inches, i said it was starting at around 2.5

with apology-

Kaleb

[RotogenRay]

I'm not attacking you or anything, I'm just saying that everyone overestimates voltages and it kind of annoys me.

I don't mean to come off rudely, just concisely.

What is the difference in breakdown and starting to you? You said "the arc starts at" and I said "the air breaks down at" which is the same thing- different words.

[kalebman5000]

oh my bad i thought you meant when the arc you know, stops arcing, by "breakdown" gosh, i messed up!

and yeah thanks for keeping this whole misunderstanding polite and civilized, unlike a lot of people on youtube!

[samssoftwareuser]

very clever, is that just with a flyback transformer?

[djspaceport]

yes

[jmartis2]

it was SONY trinitron 21" screen.

[codemsan]

oooo! i have the same T.V and it starting to go, YAY!

[jovicakluk]

hey jan this driver is really great you should put it up on 4hv. on what topology does it work

[jmartis2]

It is flyback topology (single-switch) with quasi-resonant capacitor across the primary winding.

[jovicakluk]

ok i was just wondering becausse i find purple arcs more intresting than white arcs dont know why

lol and that fly bac really is super to withstan such a high voltage

[wuminnoname]

This is great! Do you have schematic for it?

[NorthMiamiKid]

CHIDORI!!!!

[shredmaster999]

a little messy work place but nice arc

[hvhaxor]

nice man love ur work and ur trance

[jmartis2]

thanks!

[hardstyle905]

very cool sparks. can you show me the driver?

also how much power u used?

[jmartis2]

I guess aprox. 180W. The driver is single MOSFET with a resonant capacitor. Sorry I don't have a schematic handy right now

[romalittle]

today we done this experiment with glow discharge at school.

[jeonster]

Are you a ghostbuster? :)

cool vid

[triggerhappy77707]

if you gave me a schematic i could get a real idea about how to make my own schematics.i am not going to bug you about it though

[masteropie001]

hahaha that corona would fix the ozone layer

[Szajbave]

Nice , what's the resonant frequency?

are you using resonant caps in a half bridge , and a resonant L in series with the primary or what?

[Szajbave]

Nice , what's the resonant freq ?

and do you use LC series resonance on the primary side or what?

cheers

[diymania]

Puts the ZVS driver to shame.

[jmartis2]

Voltage-wise - yes. I actually got 130KV from that flyback and I will post a video soon.

[diymania]

Lets see some schemmy! mailman brought me a flyback today.

[mumish13]

nice nice nice :D

[Kilohercas]

OMFG, u get once 5cm spark, using one mosfet, what kind of driver and mosfet topology do you use, primary turns, and voltage ?

[jmartis2]

no, these are sparks starting at 10cm :)

[codemsan]

thats like, ridiculus corona!!!
