This man's is crazy. He knows exactly what he's doing, and exactly what voltage is safe. He just knows him in pain will get him even more views. Love this dude.
Yeah ikr
It's not just views. This way he makes his videos more entertaining so they aren't just watched by electricians and now have the potential to hook someone to start playing with electronics. Also he makes sure to point out why that happened after he gets shocked. That way the information followed by the shock can be remembered for longer too.
Why do people think everything is about views???? Good content is not just about views kiddo
@@AlissonSilva-ox4uzyou thought you did something by saying this didn't you? 😂
What voltage is safe? He is using almost 100 kV! Unless the charge and energy are limited there is nothing safe with that voltage!
This circuit can be used in particle physics and high energy research. Both cockroft walton and marx generator came out of particle physics and not engineering
At first I read "cockroft" as 'cookoff', like ammunition does when it gets too hot, I had no idea how cookoff could relate to electronics but the perceived danger went through the roof there for a second.....
@@zombieregime that circuit can definitely make ammo cookoff
Also lightning tests
they are also used to test the effect of lightning strikes on power supply equipment, along with electronic insulator testing.
I've been in a high energy lab with a ginormous marx-generator. It has huge capacitors that you normally would only see inside power plants or hvdc (HGÜ) stations.
@11:00 This contraption was featured on the slow-mo guys channel. A curious thing was observed: Seems the final spark gap discharges first, cascading back towards the power source. A 1 million frames per second camera barely captured it.
I've also seen that video, I'm pretty sure it is not necessarily the last spark spark gap in the circuit, but the spark with the smallest distance which triggers everything. Basically the same what happens when he puts the screwdriver in the spark gap to trigger it.
1.75 million fps!
Makes sense as a spark gap causes electrons to actually flow, and they do so from - to +.
@@paulmichaelfreedman8334 there is a growing potential across every airgap as it charges. Which one breaks down first depends on a number of factors, probably the largest of which is the distance
@@tolkienfan1972 i think the gas between the electrodes is the main factor...although distance comes close second
Mehdi did an interview some time ago. His video where he grabs the Jacobs ladder when it fell towards him. Even though the video continues seconds, the truth is he actually got shocked pretty bad. He said he had to take a break, lay down for a few hours to recover before he continued the video. The way it fell towards him, if he hadn't caught it with hands and pulled the leads off, it could have hit him in the head and could have been bad outcome.
yeah iirc he's said in other places that was probably the closest he's been to a project killing him. better wiring (both connectivity and gauge) could've been the end... scary stuff
@@QualityDoggo yep that's why he's my engineering hero, guy is an absolute genius that acts like a mad genius on camera while teaching us with real examples what happens when you don't do things in a safely and controlled manner, sure it's fun as fuck but it's also dangerous as all hell.
Nah, he can't be killed by electricity, not anymore
Mehdi.
The only time the shock wasn't planned to boot.
@11:12 I love how dude is in his hard hat and orange, pretending to be all Mr Safety, when he loves the lightning every bit as much as ElectroBoom.
I work in an electronics factory and one of my old supervisors once told us “capacitors don’t hold a charge when they aren’t connected to anything” …. I’m no engineer but have enough experience to know he was extremely incorrect.
maby your supervisor never open old tube tv😂
Great video! Been binging these ElectroBOOM reaction videos!
Thanks so much for the support 💪
A Marx generator is also typically used on medium and high voltage cable testing, in order to simulate transients that can affect cable life (switching, lighting strikes...). The waveform needs to follow a given shape and it's a bit more complex (including resistors and trigger mechanisms). The largest I ever used was 4.2 million volts, and for sure implies more safety considerations than the ones seen on this video...
you all know that electroboom is a electric engineer and its a humor/learning channel? riiiiiiiiight?, love him
The Marx type generator is used the create very high Impulse-Voltage. Because of the stage setup you Charge in parallel and you have to insulate only for loading voltage (typical 100-200 kV).
The switches are spark gaps, semispheres with an ignition lamp in the "northpole" of the sphere. During the loading process you will set a certain distance for all the gaps above the discharge voltage. You trigger the generator by an impuls of the ignition lamp. The electic field will change from quasi homogen (sphere-sphere) to inhomogen (rod-sphere) with a big drop in discharge voltage) the gap breaks down and you will add the voltage of the first to the second stage. This will caus a cascade effect on All active stages.
The form of the voltage wave can be adjusted using different settings for the resistors.
I worked in a transformer test field in Germany for a long time and a 2MV generator was all mine.
Greetings
Ah, i love this series
Keep up the.great stuff🧡
Thanks mate 🤙
Have you watched the one where he makes his electron-shooting wand that can kill electronic devices from a distance?
Oh no but I have seen her thumbnail for it. Hmm 🤔 might need to look into this
One of the more “basic” uses for this type of generator is for high voltage, rapid discharge systems where a single high capacity capacitor is just not feasible. Things like rapid function servos or accelerators (I.e. rail guns) use generators like this so that a relatively low power input can be used for massive voltage output. A generator similar to this is used in hand-held (mobile personnel carried) rail guns and light armor piercing rapid fire rail guns (often called a needle gun as the projectiles are typically thin gauge high density metals) prototypes.
I love that guy. If you need to learn from mistakes, make sure they are someone else's.
Started watching ElectroBoom back in Year 11 as a recommendation from my Engineering teacher. Haven’t stopped watching since then and has sparked my passion for Engineering
Mehdi (Electroboom) is electrical engineer, and in his videos he knows exactly what he can and cannot do. I love his videos, they are very informative
Several comments. The first thing you should know is that Electroboom (Medi) is an electrical engineer so he knows the theory and the risks.
The second thing you should know is that his "accidents" are almost all staged. Its his trademark. He is actually getting shocked but its with very low current.
A starting point for gap measurement for a Marx generator can be estimated by using 1000 to 3000 volts/mm depending on the sharpness of the electrodes. The actual spacing is then fine tuned by trial and error.
Marx generators are used as lightning simulators to test HV equipment and aircraft. There are some very large Marx generators in test facilities that take up the entire interior of a large multi-story building. I believe that some early high power radar systems used Marx generators to generate the periodic high pulsed power. Other than that they really have no other use but are very cool to make and operate.
Medi is indeed a smart dude. You sound very knowledgeable in the area, are you an engineer?
@@thinklist Yes. I'm a retired electrical engineer. Designing and building high voltage devices is my hobby. Have a look at my channel to see some of my projects in action.
Marx generators have several key aspects that make them great for certain applications:
They operate on DC - no high-frequency required like Tesla-coils.
They have nearly no power-requirements - as long as the self-discharge of the capacitors is accounted they can be operated even from lowpower sources.
They do not require any active electronics.
The discharges can be precisely controlled as it can be triggered externally - often done either through a trigger-spark at the first stage or even through UV-light.
The discharge can have incredible high voltage and power - far exceeding similar-sized transformers or tesla-coils.
This single large discharge also makes them very safe to operate.
This simplicity and controlability made them ideal for many testing-applications. Test how something reacts to lightning-strike, how good the insulation is etc.
The adventure ends when the arc gets long enough to reach your heart. How romantic
Another application for this circuit is the testing of faraday cages such as cars etc.
Edit: so yeah now that I've finished watching the video he summed it up pretty good with lightning tests
That arc reminds me of when they lighting test the stuff built at my job.
But the stuff we build is usually between 50 kV to 1 MV.
Those arcs are a bit annoying at times, when they echo through the factory.
I love your reactions each time he gets shocked.
Loved this . Great banter mate
Some smoke detector systems are like that in the US, but I don't think it's legally required so it's mostly newer houses.
I was just reading up on this after buying a house for the first time, and apparently, new construction is required to have mains-powered smoke detectors, and interconnectivity may be required as well.
It's not required for older homes but is considered preferable. (I'm thinking I may end up wiring my house for a few, just for peace of mind and less battery changing...)
Yea like Hey_allen is saying. The mains and interconnected are recent code changes as requirements.
Old ones were battery only, and chirped like mad when the voltage in the battery got low.
I love that electroboom is an Electrical Engineer and you can tell when he explains circuits and how electricity works, but once he starts building the circuits it looks like he has no idea what hea doing
I love how we all smiled and laughed same time
Electroboom is also great with editing 🙃
This is like if Doofenshmirtz had a tech TV show. the way he says "copassators" is awesome
If a pacemaker survives Medhi then it is a good pacemaker.
😆
This circuit is used in testing facilities, albeit at a much bigger scale. I was recently in a transformer factory and they had one that was about 10m tall, each capacity being about half a meter in size. It was millions of volts but I don't remember exactly. I guess they use it to figure out the breakdown voltage of certain insulators and to stress test their transformers and test against lightning strikes.
Also my university has a high voltage laboratory and they also have this circuit, it can make at least 50cm arcs.
You are correct on your guess.
Thats correct, i am working for a distribution network operation service in Germany and we use this big marx generators in our testing facility to test insulations of big cables.
These type of Marx generators are used in transformer manufacturing facilities to perform impluse testing. The huge transformers used by utilities are basically hit with a bolt of lighting and a bunch of measuring equipment is hooked up to measure it and oil samplea are taken and tested to check for break down of the oil which can indicate shorts and other such thing. This technology is actually very useful to ensure our utility level transformers meet requirements and will not just break down when operating.
Thanks, TH-cam Recommendations for this awesome video!
Finally a new reaction i am so happy thank you please do more please please
😆 you will be happy to know I’m editing another one right now. It’s something a little different so I hope you like it 👌
@@thinklist Yeah i am very happy and amazed to here that 😅. Maybe you could start also livestreaming just as an idea it would probably give you a lot of attention. And i think you found a gap for your content where it perfectly fits in due to the fact, that you are like one of the only electricians which reacts to that kind of stuff.
The application is you can create an impulse generator. The impulse generator is used to simulate lightning impulses and switching impulses on electrical equipment to test if they meet their rated BIL strength. It is very difficult to generate a 200 kV. You can use a wave shaping resistor network to effect the charge time and discharge time of the pulses.
I suppose such high voltage discharges also wreak havoc with any electronic devices close by due to the EM pulses given off by the discharges.
His head was too close too that thing 🤣🤣🤣
He did say what it could be used for, he said lightning tests, I would imagine it could be used for any application that requires a large discharge of an extremely high voltage at a very small interval
Love this video!
There is a practical use for these circuits. Voltage Multipliers are used extensively in the Semiconductor industry, particularly on High Voltage, Low Current Ion Implanters.
this vid is older, but it is a great simple multiplier for non-AC situations, simple in construction and hard to break.
a Cockroft Walton multiplier uses diodes instead to charge the caps in parallel on one half of the wave and put em all in series on the other half of the wave, but that only works for AC, and diodes/semiconductors are sort of easy to destroy
this circuit can be used for simple DC powered tesla coils or i guess even short x-ray pulses, or EMPs...
cockroft waltons on the other hand instead are used in a lot of circuits, like most "modern" CRT flybacks have a voltage doubler inside, so do microwaves (only single stage), even those battery powered electric flyswatters, and i've had those kind of corded bug zapper lamps where i'd expect them to have transformers inside but instead found capacitive voltage doublers (also explains why they make such a "loud" noise when they discharge and zap an insect)
The marx generator can be used to emulate lightning impulse voltages or switching transients. They are used to test high voltage equipment.
I used a cockroft walton multiplier in a 12V laser power supply to boost the 3,000v output of the inverter to 18+kv to start the laser tube. Once started the CW multiplier was effectivly bypassed, as the tube only needed the pulse to start, 3kv was enough to keep it running.
I just looked up what in the hell a Cockcroft Walton Multiplier was. ITS BEAUTIFUL 🥹
@@thinklist I really love the CW Multiplier. My Neewer NW-800 mic came with a super basic phantom power supply that has a 2.5 stage CW multiplier inside of it to boost the 12VAC input to the 48VDC required to charge the condenser with a sufficiently strong electric field for audible sounds to produce clear audio signals.
everyone keep saying they're build different but the only one that can prove it is none other than the electro _immortal_ boom
IIRC when it comes to voltage gaps, the resistance of air works out that every cm of gap = 10,000v when you get a spark, so an 8CM gap would be 80,000v
I've put my arm inside a washing machine while it was plugged in once and it is an unforgettable feeling when you get shocked. Took a few moments before I could unclench my fist. For 15 minutes afterwards I had this feeling that I may have a heart attack.
I've used Marx generators to simulate lightning for large utility transformers. One customer would always require it but it is considered to be damaging so is generally not used on every transformer, more of a design verification than production test. I've always wanted one of those suckers for my back yard, my wife has a different opinion.
Oh I needed good laugh. Thanks
Never has the term, "tickling the dragons tail" felt more appropriate
Thats a real neat and clean hardhat👍🏻
There are some applications for this circuit, the one i know of, its to test electrical isolation in transformers with electrical pulses/arcs.
Hey! Electrical Engineer from Brazil here. 😃👍
I liked your react, subscribed!
The circuit has a use, besides the flyback xfrmer used in CRTs, which is HV testing of insulators and devices designed to operate at that high of a potential. However, a flyback xfrmer is extremely dangerous in itself, as well as the charged CRTs they were connected to.
I ran a repair shop at the end of the CRT type TV repair industry, and when changing out a 25-inch color CRT, which I had discharged the aguadag and plate on (25 kV), it still had a residual charge in it, I later found, and when I lifted it, I was bitten. The next thing I remember, I was waking up on the shop floor, and I was surrounded in shattered glass. It is dangerous, and I was very lucky.
This circuit and other similar circuits are used to simulate power surges and lightning strikes and equipments and are used to test dielectric mediums ✌️
When I went to electronics school in the ARMY the teacher always had a charged capacitor so if you fell asleep he would yell at you and then Tossed it at you .
electroboom is why you dont leave igor alone in frankenstien's laboratory.
6:50 your humble ozzy-mozzi made in china electric zapper! 🦟⚡⚡⚡ I scrapped one of those cascade capacitor circuits from a zapper and still have it gathering dust in the back of my desk 🤣
HV is needed to test insulators on power transmission lines, to excite lamps for pulsed lasers, to study arcs and lightening, to measure the breakdown fields in materials, etc.
Look up Z machine. Not only does it use a Marx generator at HUGE scale, but it uses a laser pulse to ionize the air gaps all within a small timeframe. The pictures are absolutely astounding!
Well if I remember correctly, a Cockroft-Walton voltage multiplier was used to accelerate ions to do the first ever man-made nuclear fusion!
The calculation for the gap is done by making the gap the largest possible while still being shorter than the distance between the capacitor leads than increase voltage until arc lol
That would make a bad ass taser
This is how you die and meet your maker in a sec
One of the uses of the marx generator is to make lightning at the lab so you can research about insolations or lightning protection
True
he has been electrocuted so many times that he is immune
Got to make me one of those. Electronics technician here with 35 years experience including EHT. So no fear, just respect for electricity.
I really love his video and your reaction. Learn to awareness and safety about electrical
That's a scary bag in the wrong conditions.
It only makes it funnier that electroboom shocks himself intentionally
You set the gap to the distance for the voltage you want, you can find spark gap calculators online
I also got zapped by a capacitor a few times 😂😂😂 I keep forgetting that it holds the charge
8:00 sick electro beat
Had an HV transformer that took 110AC to 60kV. Ran ground wire to make an air gap. We call it sparky. Sounds like a gunshot. Scared the you know what out some people in their office and one guy scared some squirrels off his bird feeder.
As for the us smoke detectors some also run off mains but there are some that do run off battery only and once the bettery gets low before it dies out it will make the smoke detector beep lightly to inform it needs to be changed
The way he scratches his head just kills me 😅
That jacob's ladder clip is bonkers. I truly hope there was someone off-camera ready to cut the power
Nope. He admitted he just got very, very lucky.
The worst zap I got was from a 150lb, 32" Sony Trinitron, HT lead and it was a stimulating 50KV. Stings a bit but less than dragging all your knuckles at 40MPH across the back of a through hole PCB.
8:50 and here is the difference between an engineer and an electrician.
We engineers are mad as hell. (sidenote: also there is the gut feeling of just how much energy can be stored in those caps... Mehdi probably dealt with higher energy sistems in the past, thus the bravery)
love that he wears a hardhat just to prove hes a engineer
Mains powered smoke detectors with interconnects are code in the US now. I'm not sure when that happened, but my old house, built in 94, had battery powered units and my brand new home (built in '22) has mains powered ones.
my guy wakes up tasting batteries
Keep in mind he is sitting on a platform that is very thoroughly isolated from ground this is why he is able to slide the wire backwards without it traveling to him its also why he was being careful at that moment to only have one hand near the project
The smoke detector in electroBOOM house is main power
Fun thing about completing intermediate voltage AC circuits (277 V): they can and will force all muscles in the line to contract at full strength, even if you have dry skin.
Source: i'm a dumbass and hand my left hand on ground and completed it with my right hand to common. That shit was surprisingly not the painful kind of electrocution i was expecting, but i was left very sore.
I know that the vast majority of smoke detectors in the US run on mains as well as having a battery backup, and also do the short, loud beeps when the battery's getting low. Ours took it a step further and went off at random times, including in the middle of the night. Good stuff.
The Marx generator could be used to do lightning impulse test in high voltage equipment. This is to test the Basic Impulse Level (BIL).
Microwave Acceleration unit for space travel, using it for cold start. Or if energy gets to a Minimum to jump start something like a Newman type motor to accelerate it to higher and Output Speed. And this scale is the perfect scale to do so.
2:08 this is the second extremely close call to death beside his jacob's ladder vid
he didn't have time to even curse and tried to hold his heart to apex, i can't even laugh of how serious this is.
I do often wonder what is real or fake but yep I agree this looked petty real
@@thinklist most of his fails are staged, as you can obviously see Mehdi is smart, and clearly knows what he is doing. But Jacob's ladder fail was real. It's a miracle he survived it. He mentioned that in one of his interviews.
@@voidseeker4394 he’s bloody lucky then
This was not extremely close to death. that supply was not powerful enough to kill you.
Oh yea this is amazing
When dude starts arcing gaps wider than 3-4 inches you slinging some voltage. I got hit by a Jacob's ladder not long ago. This stuff is fun but, it hurts bad when it bites you.
The Science Museum in London used to have a 1 megavolt impulse generator. It was a huge thing that took up two floors, in an enclosure made of toughened glass. Twice a day they would power it up and launch a couple of massive loud sparks. Amazing!
Love it 👌
This guy has had more electricity flow through him than a Luminen of the Adeptus Mechanicus.
From what I've seen the generator is basically used in physics and to test the effects of lightning strikes on aircraft, buildings and powerlines.
Electroboom seems like a great value supervillain in training.
Surprised he hasn't made an electric bong out of that
He is an electrical engineer, you are an electrician. They are not the same.
Some people are watching horror movies to relax their mind after watch ElectroBOOM videos.
They always say "don't play with fire" but I think playing with electricity is probably less safe than fire because as someone who works on a lot of electronics including very powerful commercial microwaves this shit was setting off all the danger alarms in my head.
The practical application in a world ender device like the death star.
my bruddah he's making a tazer
2:09 🤣🤣
The us has it to were the smoke detectors are connected on their own circuit but they also can run on battery and chirp at you if the battery is low
Even though his arm gets closer, the route to ground is much lower through the spark target
