[bundawartini]

Your Video Is Very Useful Sharing My Marx Generator producing 180kV sparks. Built using cheap chinese capacitors and standard 1W resistors.

[LUVB6CPPgmodcsscoder]

I seen those caps before

[gyopicyan999]

Sugeeeeeeeeeeee!!!

[kmncztms]

Whoa, that looks brutaal, What if you use a marx generator in a tesla coil? ;D

[Janigut]

What shop did u order the caps from?

[Uzzors2k]

@Janigut I can't quite remember, and I'm not sure they'd even have the same name anymore.

[chilidress]

zvs flyback and the marx generator?

[psycho2061]

could anyone tell me the values of the resistors and capacitors

[paulius360]

@psycho2061 cheap for few $ from ebay you can get like 50 or 100 resistors an capacitors

[lokeycmos]

good job! urs is much faster than mine!

[Uzzors2k]

@lokeycmos Thanks. I recently rebuilt it into a vertically standing version. The problem however is that without something to arc against, the sparks are significantly less bright, even in total darkness. Something to keep in mind when constructing a Marx generator with such small capacitors.

[hvpower]

Wow, really amazing results! I like your projects. Thank you for posting this.

[jeffddow]

hey please answer what do the resistors and spark gaps do for this circuit? what makes it work better than just capacitors in parallel?

[Uzzors2k]

@jeffddow With a bunch of capacitors in parallel there would be no voltage multiplication. The resistors provide enough impedance to make it appear the capacitors are in series when the spark gap fires, thus you can charge capacitors in parallel and discharge them in series.

[Gmc42082]

@Uzzors2k yeah it looks just like a voltage multiplier circuit minus the diodes.

[lokeycmos]

@jeffddow basically the marx generator charges up caps in parallel and discharges in series. the resistors are high value and charge up the caps. when the caps are charged with enough voltage to jump the first gap it causes a cascade and output is source voltage times the number of caps.

[hannobisschoff1]

Nice, but that is no where near 180 KV. 1 KV = 1 cm. That's about 30 KV

[Uzzors2k]

@hannobisschoff1 No, the rule of thumb you're thinking of is 1kV = 1mm, which isn't entirely correct either. I just used it like everyone else for marketing purposes. I've constructed, and measured the output voltage of a power supply using a meter to 60kV. This power supply would spark over in air at about 6cm distance with sharp electrodes, so I can assure you that you're mistaken.

[Uzzors2k]

@Uzzors2k Just to be clear, the 60kV power supply was a CW multiplier, not the Marx generator in the video here.

[Andreas861993]

@hannobisschoff1 no 1mm is 2-4 kV !!!

[Sk8erwms]

mit ner batterie betrieben :D

[tyronesantikaTV]

how do you make that?

[Landotter1]

what you gonna power with that monster? Maybe a small TC?

[Uzzors2k]

@Landotter1 It's actually not good for much more than show. If it was more powerful it could be used to power an x-ray machine.

[JerryGiesler09]

Ihatebrazil3, this is a spam! Take that post off or I'll flag you.

[JerryGiesler09]

Almost sounded like a sick AK-47 firing out rounds after rounds... XD

[KiKoS657]

touch it! :D

[dumle29]

would a bug zapper transformer work transformer work? (those handheld ones that run of to AA bats)

[Uzzors2k]

@dumle29 I don't know, I've never seen one before. If they produce DC, or can be rectified they'll probably work.

[dumle29]

@Uzzors2k these ones: seenontvproducts(dot)net/bug-z­apper/bug%20zapper.jpg

[Uzzors2k]

@dumle29 Maybe. Open one up and see if they are usable.

[dumle29]

@Uzzors2k well i dont really know how i should messure the output. do you think an ordenary multimeter will work?

and if im correct it should be dc for it to work.

if there isnt sufficient volts could i link up two in series?.

[Uzzors2k]

@dumle29 It would probably be easier to check the output section for diodes. The transformer of the frequency and it's voltage will probably mess up a multimeter. Since these are battery operated you can series many of of them once rectified.

[leigh7801]

just a small question. how have you measured the volts. i need to measure volts over 1000 but my multimeter only goes to 1000 (i think all do 1000max) how would i work out how many volts i achally have? cheerz

[Uzzors2k]

@leigh7801 Measuring the voltage of a Marx Generator with a multimeter would be impossible, since the voltage is only at it's peak for a very short duration. If you want to measure the voltage of a DC source you can use a resistive divider to reduce the voltage your meter reads.

[TheProPilot100]

HOW DO YOU MAKE THIS SEND ME THE COMPONENTS OR MAKE A TURTORIAL!!!

[TheBullShitCompany]

wow



[agrajag46]

I'm surprised that your video camera isn't tweaking out from the impulses.

[qrrak]

dow do you make work a transformer with dc ???

[xmlisnotaprotocol]

tidy rig!

[dundermiflinpaper]

byfar best marx generator yet, great job!

[panzuman]

this is by far the best marx generator ive ever seen 5 billion stars*****

[Uzzors2k]

Hehe, thanks. :-)

[panzuman]

you think you could make a tut?

[Uzzors2k]

Meh, tutorials require too much tutoring. I'm in this to teach myself, not others, so my website is as close to a tutorial as anything I'll do. You saw the link in the video description, right?

[panzuman]

whoops over looked the link saw it as tags thanx :)

[thedofrun]

wow great marx generator, very neat one of the best ive seen. is it possible to make a Marx Generator using only a 9V or say 12 volt supply.

thanks very much

[Uzzors2k]

This one runs from 12V, but if you mean without using a high voltage transformer then no, you can't. The spark gaps need to arc-over for this design to work, so the minimum voltage you can use in air is about 600-1000V.

[randomsrvapps]

@thedofrun yes it is with voltage multipliers

[Driv3th3hiv3]

Is this lethal?

[VitaliyStepnoFF]

Yes, very!

[coilsinamotor]

wow!

[coilsinamotor]

im pretty sure it is like its 180 kv i mean common of course its leathal!

[Driv3th3hiv3]

Thats dumb

Because even a 30 million volt shock under at low current would do nothing more than zap you, not kill you

[coilsinamotor]

im not bumb thank you but still 180kv at around only 1mah will still hurt allot so it my not be leathal but still it would hurt alot now please dont call me stupid thank you

[Driv3th3hiv3]

It's not 1mah (milli amp hour)

It's 1MA

and it is also the minimum amperage at which a human can feel an eletric shock sensation

[coilsinamotor]

oooook

[AquariumNerd1]

@Driv3th3hiv3

a 30 million volt shock would have a voltage higher than man has ever created,

[toadsEATbugs]

@Driv3th3hiv3 I can't believe your comment got thumbs up. Marx generators are the most deadly high voltage device because they send out a highly concentrated short pulse.

[RadusAndroid1]

точно :)

[TERORISTsaimonxk]

автомат какойто !

[imaqtlolz]

huge arc

[RoninGale]

Do you suppose adding a small magnet at each gap would "quench" the arc,thereby increasing the pulse frequency?Tesla was fond of this approach.

[Uzzors2k]

It could, I'm not really sure how much of an effect it would have though. Try it!

[sakcheegii]

Could you touch to the arc?

[Uzzors2k]

I was being zapped by accident on one occasion and didn't notice until I saw the sparks. This was during some experiments with a large HV rectifier, and the sparks had first traveled through oil and 3mm of PVC, leaving them significantly attenuated. A direct shock through the entire body would likely be lethal however.

[kalebman5000]

Breakdown at that length is pretty impressive!

[rabidsnakemonkey]

So if you connected a coil to one of these, couldnt you make an elecromagnetic pulse, one theoretically strong enough to really do some damage?

[Uzzors2k]

Not really, an EM pulse requires a strong magnetic pulse, which in turn requires a lot of current and not much voltage. Even ring launchers, rail guns and coin shrinkers are harmless to electronics placed more than a few meters away.

[Yumminess0]

what are the specs of your power supply, resistors and capacitors?! Awesome!!!

[Uzzors2k]

There's a link in the video description to my website, it explains how I made it.

[HLSDK]

BANGBANG! I like your site :-p

[tulvatalo]

tnx

[tulvatalo]

does this produce uv waves

[Uzzors2k]

Yes. All spark discharges in air produce radiation in the UV range in addition to visible and IR light. Using sparks as a UV source is how TEA lasers work.

[HVdischarge]

hi, i understand that all spark discharges emit uv radiation (as you said) i have also been told that they emit X-rays too... could you confirm this? as it would explain why all my camera films are wrecked! lol

[Uzzors2k]

Negative. X-rays are created when high energy electrons collide with materials causing excitation. The electrons flowing through a spark in air collide with so many molecules (creating visible plasma) that they loose too much energy to cause an X-ray photon to be created on impact. So X-rays can only be formed in a vaccum.

[HVdischarge]

ok thanks... so even if the two electrodes are really close and you pump loads of power through the air... you still won't be emitting x-rays? i just can't figure out why all my camera films are wrecked...all 4 of them. this is the only thing i could think of.

Thanks,

do you have a video of the coil gun on your site? nvm... i will look now :-).

[Uzzors2k]

Nope, air is surprisingly dense with molecules. The mean free path in air at STP is only about 65 NANO-meters. In comparison the wavelength of violet light is around 400nm. So electrons have no chance at being accelerated in air.

How are your films wrecked? The UV pulse from a Marx generator is extremely short, but intense, so it might be overexposing the images.

[HVdischarge]

hi thanks for the help.i will have a look at steves website in a sec... maybe my marx done it then :-/. do you think a sheet of polycarbonate infront of the lens would block the UV and prevent this from happening?

[biowerks]

I think that a piece of glass will block the UV light.

[HVdischarge]

glass? cool, i have loads of sheet glass laying around :-P. Thanks

[jchap26]

Actually if you overvolt a gap enough with a picosecond risetime you can create runaway electrons in air that produce hard x-rays

[HVdischarge]

HI, thanks for the reply. everybody says something different! lol.

my tutor at college attended many, many years at university studying electronics, science etc.... and he says that almost all HV discharged emit X-Rays but everyone says something different lol.

[jchap26]

Again, only in very special conditions can X-rays be produced at atmospheric conditions. They are certainly not produced in this video. The field in the gap has to reach many times the DC breakdown threshold which requires very fast risetimes.

[m3sca1]

nice.

[xmlisnotaprotocol]

cool

[minde4000]

Rofl this is nice.

[robertcruickshank]

Very nice!

[vivdal]

Hello,thanks for the advice and response.

You can see it posted as My Marx on you tube.

Sorry about the picture quality I didnt want it too close to my computer!

[vivdal]

Hi,Im stil enthralled by your video.

I contructed a eight stage 20kv 1nf,with 2M 2Watt resistors and it works instantly emitting 4 to 5 inch sparks,though i have insulated diligently,I have found that a slight increase in spark gap distance increases output.I uesd 10M resistors for blast.Thanks for sharing your gift.

[Uzzors2k]

That's great, post a video!

[vivdal]

Very inspiring.

I am attempting to construct using 1nf 20 kv ceramic capacitors and 1M restistors,with liberal use of heat shrink where appropriate.

Is my component choice sound?

[Uzzors2k]

It sure is! Standard low voltage 1M resistors or HV ones? The little 1W ones will arc over and need to be put in series. Their actual voltage rating is only around 500V per resistor. :-O 1nF capacitors will slow the charging speed but give fatter and brighter sparks.

[vivdal]

Thank you for your advice.

I will try 2Watt 1M resistors and 1nf 20kv capacitors.I will let you know the results..

Thanks again!

[TCDIL95]

holy shit, that is some good arcing!

[HVdischarge]

nice! yours sparks really quick! i was going to build my fist marx generator and am waiting for the components to arrive, i will be using a microwave oven transformer with a sec output of around 1.5-2.1kv @ 500ma.

any advice?

Thanks

[MadsKaizer]

be very careful with MOT, since the current is so high on the secondary, if you can try and find a replacement as f.ex. a flyback transformer instead, for a marx you are better of with higher voltage and lower current.

my marx is with 4kv input and 6 stages, it was good for education but you with so low voltages you need alot of steps to get good sparks.

[HVdischarge]

i know what you mean, ive had 3 shocks of it so far (im pretty sure i should be dead :-/)

i am currently looking to buy a 10kv neon sign transformer but they are so expensive, and im only 16 so i dont get paid very much

:-( lol, and im not sure about flybacks because they hold energy like caps...i think, and people say they burn out easy.

[Uzzors2k]

A MOT is total overkill and poorly suited for running a Marx generator. It will need rectification and setting the spark gaps will be difficult with such a low voltage. A standard flyback transformer works perfectly and shouldn't ever burn out.

[HVdischarge]

thanks again for the reply, ok... i have seen them go for about £10.00, could i use a cheap old ne555 timer as a driver circuit or something better? also the ones i have seen have like 8 solder points :-/ .

Thanks

[Uzzors2k]

I used a basic 555 timer circuit with no extras. It's all you need. Monitor flybacks with many pins have one primary winding which can be used, you'll need to experiment in order to find it. Otherwise you can wind your own primary on the exposed core.

[HVdischarge]

great :-).

Thank you so much for your help :-)

[HVdischarge]

my flyback has arrived...i assume the suction cup is the + hv output? but what do i do with the 2 wires going to 2 dials saying focus and screen? do i need them?

Thanks again!

[HVdischarge]

i have found a flyback on ebay... should be here in a couple of days :-). if i wind my own primary with 1-1.5mm enamelled copper wire, won't i need a current limiting resistor to limit the current to the primary everywise it will take like 80amps and burn out instantly (along with my battery).(this is on the assumtion that i can use a 12v SLA battery)

Thanks

[codemsan]

they dont hold the voltage, the CRT does, and they only burn out quickly if your trying to cram too much power into them :)

[HVdischarge]

hi, thank you for the reply... dumb question coming.... whats a crt? lol. is that the tv display?

Thanks

[codemsan]

it stands for cathode ray tube, which IS the t.v. display, the glass part!

[HVdischarge]

oh right, i thought it sounded familier lol.

thanks.

[Slu1982]

ładne :)

[FireBirdsGo]

Awesome! Nice little setup you have there. This really makes me want to build one lol :D

[triggerhappy77707]

great!now i have to build one though...i need a website too..
