Triggered Spark Gap High Voltage Switch

[@darrellpidgeon6440]

I love the sound of a spark gap in operation. Must be the "mad scientist" in me (haha). I've got a couple of those high-voltage devices laying around here somewhere. I've wanted to use one to test as a driver for a mini tesla coil. But it is nice to see there are other uses. Thanks.

[@alichank]

It's just like super high voltage non-polar transistor, but only from middle wire to one of thick wires

[@johnrouse6957]

I love to watch you and Robert Murray Smith. You both take very complex concepts and make them accessible THROUGH hands on experiments! Thank you for sharing your knowledge through experiments that can be reproduced.

[@ludicscience]

thanks!!!!!

[@Buzzhumma]

Very good simple design! You can create system to make flash graphenr with this . Would be great to see. You can also create switch using lighter ! Best use long match stick to avoid shock !!!

[@superdau]

Get rid of the crocodile clips and use soldered wire or screw terminals. The clips, the thin wires in cheap versions and the often badly crimped clips have an awfully high resistance for an experiment like this.

[@anshajkumar6542]

Please use a induction cooktop as a zvs driver for a metal heating induction or flyback

[@rob3125]

Ingenious, but if it back feed wouldn't it damage the high voltage power supply?

[@ludicscience]

No problem until now

[@Buzzhumma]

You can put diode if you like !

[@Buzzhumma]

The power is not in parallel so it should not happen !!

[@bagstermucha]

I had the same idea recently. I tried to do it in falstad and was curious if it would work. Thanks to you I am sure it will work. Thanks

[@yougeo]

also causes a very brief duration current flow like the tesla hairpin circuit because the air ionize darea is blown away by the magnetic field of the current suddenly flowing through it so is self quenching. look up tesla hairpin circuit

[@lazardjukovic1691]

Make a coilgun with this system

[@FaysalKhalashi]

i have seen spark gap.. but using another spark to trigger the spark gap switch 😵😵😵 wow. is this something new??. thanks for the video...

[@EdwardTriesToScience]

the higher voltage jumps the gap, and the lower voltage which you are switching also connects because an arc is like metal, it conducts

[@alphonsesynrem28]

Awesome, damn, spark gap as a switch?? Never crossed my mind though knowing the fact ionised air is conductive.

[@d1rtba9]

Used as switch for first nuke tests, since normal switch arcing would have caused the electric detonators to be milliseconds out of sync

[@221b-l3t]

​​@@d1rtba9Yes krytrons synced the signal to the detonators to go off within one microsecond of each other. You can actually buy them online but not shipping outside the US :( Would love to have one. There even advertised as "type usee in research at Los Alamos". What had been occupying me is if a single krytron is sufficient or if we would be dealing with a cascade. Say one triggers two, then four until you get to 32, so 6 stages. And of course all the wiring would have to be absolutely identical and same length as length of a cable does begin to matter. I do wonder if a single air gap switch would suffice or if you just hook 32 circuits up to that, there would be some delay between the first and the last signal, so hence my thinking that perhaps multiple stages of air gaps would be needed. The bridge wire detonators guaranteed that once they got power they would ho off in a very predictable way. Thin wire gets hit by 5000 V and explodes near instantly. Since it's no good to have a microsecond synced signal and then each det takes a different amount of time to go off so both components are crucial along with the lenses but you can look at declassified French video that shows the exact geometry of the lenses lol. It's actually quite simple. The baratol is in a half sphere not the often shown oval shape. Makes sense, the shockwave is spherical so it would take a spherical chunk of slow HE to slow it evenly and form a converging wave front. Thin Man was cancelled July 17 1944. Meaning the entire Trinity ans Fat Man, design, manufacturing (not trivial) and testing took place in a year. I believe this is key. It simply cannot have been too complex. It likely is the simple answer. No magic. Krytrons, exploding bridge wire dets and spherical lenses of relatively simple geometry. That's it. And the plutonium of course. That's the actually hard part. Need a reactor to make it. And U235 would be way harder again. Even the urchin is declassified... no wonder NK managed it. It's really not very hard. 1940s tech. Barely any more complicated than a microwave oven.

[@crazykoala2289]

Instead of using high voltage power supply, can we use lighter to ionize the gap? just asking

[@l3p3]

It should work, good idea.

[@alichank]

I tried to do it, but it doesn't work

[@angelocacciapaglia1746]

good morning, listen to the video, it's very instructive, a question to be able to have a pulse in a nanosecond, could you give me some advice on testing diodes. Kind regards

[@Bro1774]

Nice video.well explained

[@erdum]

make an video about spark gap transmitter and receiver.

[@foureyedchick]

This is a "one-shot" type of high voltage generator circuit, sort of like a camera flash circuit, right Mr Ludic?

[@ludicscience]

hi it is just the switch part

[@thundercats475]

where is the capacitor charging power supply in the diagram iIneed to see how you connect? Thanks a lot

[@ДҜ74Џ]

We use triggered spark gap switches for our Exploding Bridge-Wire Detonators and our Foil Slapper Detonators

[@221b-l3t]

Did you use a single spark gap switch or did you have multiple in a cascade to achieve the microsecond sync of the bridge wire dets?

[@drstrangelove09]

For that HW0000543 device. Does the plus side of the battery connect to the red lead and the negative to the green lead?

[@standbyme6395]

Would a spark gap help mitigate an emp

[@jaidheersirigineedi8110]

Nice video LS

[@thundercats475]

what would you do if you needed repeated spark gap pulses?

[@stefanpejak9131]

You are great channel. I learned 99% from you.Thank you.

[@kyuzo9999]

great video, thank you, can this set up be used for Tesla coil?

[@anshajkumar6542]

Yeah it can be used i made one

[@Taran72]

Wow! A really smart solution!! Thanks for sharing.

[@tcoo1999]

Great video as always. The high voltage supply that you are using to ionize the air, could you not use that to charge the capacitor bank and make a circuit similar to a Tesla coil LC circuit? (the primary coil spark gap circuit). That would eliminate the need for your capacitor charger. Or is it that the caps you are using are not rated high enough to with stand the Kv coming from your HV supply? Thanks

[@Buzzhumma]

The caps are only 700 v

[@adamtyler6746]

How many joules is stored in that bank< I really feel like 700 volts should blow the wire. I ask bc I plan on using a spark gap to discharge a cap bank as well, I wonder if there are losses in the gap. There shouldnt be..

[@ameristanbouli5063]

This is smart love it

[@BamaDega]

Great video, as always! Hope all is well, and best wishes!!!

[@ludicscience]

thanks!

[@foruzeshpatrick2053]

I have connected 20 Maxwell 2.7V super capacitors in series and I am going to spark, but with each spark the voltage decreases a little from the capacities. The total charger of these 20 capacitors is 55V DC. How should I connect them together that 300 output voltage?

[@ludicscience]

ok

[@davidstelmack6899]

High power thyristors aren't all that expensive anymore. Prices have gone down considerably over the last 5 years.

[@user-bh2hs3yi9c]

Paisano, reconocí la voz, Felicidades.

[@foruzeshpatrick2053]

I connected 20 Maxwell 2.7V super capacitors in series and I want to spark, but with each spark the voltage decreases a little from the capacities, the total charger of these 20 capacitors is 55V DC and when I connect them in parallel Their output voltage is 2.7 volts, how can I connect them to get 300 volts output?

[@ludicscience]

you need 112 capacitors in series for 300 v output. I do not recommend that. you can die from that discharge

[@manishnebhani6657]

Really clever 😃

[@republicoftutorials6068]

this is gold

[@DIYwithBatteries]

Heyyy 😃 what's inside it🤔, make a video on it!

[@128Wojtek]

Hey. Hmm, Diode Gone Wild has made a video about autopsy of one of this high voltage module ;)

[@electronresonator8882]

when you said to bring closer of the contact, I thought you will go for solenoid, or maybe using a speaker, ... but then you use the tazer instead, ...but yeah both ways cause a lot of noises, I wonder if there's a way to make it silent

[@ludicscience]

it is very noisy, i will enclose it in a box

[@gussygoro2469]

That's really super.
