The "small arc switches big current" thing is used in TIG welders. When you first strike the arc, it pulses a high-voltage between the tungsten electrode and the object you're working on, which is grounded with a clamp to the welder. Once the arc strikes, the welder switches to pushing high-amp, low-voltage current through the ionized channel created by the high voltage arc, and the heat released by the now high-current-low-voltage arc melts the metal you're trying to weld.
can this principal somehow be modified to build a device that would make a continuous arc? i would like to modify my stick welding machine to have plasma cutting capability's without complex electronics... (old school)
@@ozb2006 Connect the positive to a tungsten tig welding electrode so it doesn't melt, then you want to supply compressed air to the arc so it blows the metal through as it cuts. Boom, you've got a plasma cutter from hell. or you could just buy a Chinesium plasma cutter for less than what you'd pay for just one good tig setup probably :P
@@jimmio3727 lol amm i already modified my walmart ac stick to DC and then added flux core into the mix, i am planing to add gas to this monster so why not add a plasma dead and a high voltage source and turn it into a plasma cutter? right?
Three years ago in Keysight's giveaway, I won the same model DMM you use in this video. At the time, I was in college for my EE degree and trying to support a family of five. My cheap multimeter had recently stopped working, and a new one wasn't really in our budget. Receiving a new one was such a blessing. I'm so grateful to Keysight for their generosity, and to you, Mehdi, for promoting such an awesome event.
I'm sure this principle is indeed used in industry, but it is also used in something anyone can cheaply purchase: a disposable camera. The xenon flash bulb is wired in parallel with the capacitor, but the voltage isn't high enough to jump through the bulb and create the flash until an even higher voltage trigger pulse is applied near the bulb. It's been a while since I've messed with these things in particular, so I might be rusty on the details, but it's definitely the same principle at work in a household product. Fun stuff! All that said... Heed the warnings not to open cameras unless you want to get zapped with 330VDC. NOT a fun time!
Or, do open the camera, pay your tribute to the zap god, and then casually leave the (charged) capacitor somewhere in the lab for the next unsuspecting pokey-fingered person... ;)
Regarding the USB-C charger: A proper USB-C implementation wont even give out 5V unless there are two 5.1k resistors connected to special pins (CC1 and CC2), meaning if you connect two USB-C chargers you get 0V on the cable.
Curious, would the same implementation be an issue with USB a charger and cable? Assuming you got a male -> female adapter for one end. Why wouldn't it short due to high current?
Relatedly, Hackaday has been doing a series on USB-C for the past few weeks... I learned that male-A-to-female-C adapter plugs are _explicitly_ forbidden by the spec. Why? Because if you plug an A-to-C cable into the adapter, you essentially create a cable with two male-A ends with no control circuitry in between, that you can plug into two computers (or two ports on the same computer) and make !!Fun!! happen.
@@ProtoV33MK1 No, that's not the problem. The problem is that devices at both sides would be trying to provide 5V power to each other, and connecting different power supplies together is far from recommended. It can work, but you're opening yourself to a ton of potential problems, especially when the power supplies aren't well matched which results in back-feeding ("negative amps" for one power supply) which, unless the power supply has protection for it, can result in some fireworks.
@@ProtoV33MK1 male A to male A cables are explicitly forbidden by the USB spec. That is why B exists, simply to allow male-male cables without making loops possible.
@@TheToric meanwhile i have male A to male A cable just lying around, that was shipped with galvanic insulation module for the oscilloscope to power it. Yes, the unit has female A connector on it as power supply input.
It is so enjoyable, even satisfying, to watch some other guy go on as i did as a child with electricity and things that go BOOM. When i was 15 i experimented with radio tubes. One of the simplest constructions i made - Was supposed to flash a 220V 60W bulb at 1 Hz. It was a glimmer tube resonator operating from DC voltage made by a plate rectifier. It worked well for about 10 seconds. Then it did something else. Once a second the plate rectifier shot out a bright blueish plasma beam a metre out in the air in front of me. Problem was the mains switch for my contraption was on the other side of the plasma bursts. You learn something every day. 😋 Cheers from Sweden. 🍺😀🇸🇪
I worked in a Microbee repair shop a very long time ago. A teacher brought in a system that somebody had managed to get 240VAC down the 5V power supply line. He wanted to know if it was repairable. There were craters in nearly every chip. Very impressive
@@---------------------------.. How interesting! Looks like Tom Gleisner plays Wallaby Jack, and he was later involved in the production of Russell Coight so makes sense
"Overthinking creates problems that don't exist." -Thats a really good lesson and coincidentally the title of a book. It applies to everything in life not just engineering!
The tires (and the entire machine) often catch on fire (the tires ignite), and after a while it will fall out of the sky. Riding it out is far more dangerous than you think. Often the engine quits running so you can't back out of the powerlines. Often, the operator gets shocked when he climbs down instead of jumping. Often he becomes desperate and tries to shimmy down. VERY dangerous stuff.
Does no one in this thread understand sarcasm? I'm by no means keen to electricity in how it works, etc, but even i know that you would not want to just sit there. Pretty sure common sense says that
For esd sensitive environments, there are lots of precautions that are taken place to reduce the risk of esd. I work as a pcb assembly specialist, and in the factory for example, we have a special kind of flooring that is always grounded, conductive work mats on the work benches, wrist straps, esd shoes or heel straps and a jacket that is anti static that you have to wear whenever you're working at your bench. We also have to test ourselves every morning to make sure we are grounded and are not allowed to work or sit at our benches until we have done that. That's only a small amount of the things we do to reduce esd risk!!!
Also used as the initiator for the explosives in a nuclear weapon... all the explosive compression panels must go off simultaneously, to uniformly compress the fuel past its critical mass. Any deviation in timing could result in a nuclear fizzle. Oh, how wild it is to see how far our species has come in such a short period of time.
I designed and built high voltage / high current pulse switches based on that principle many years ago. The switch consisted of two large metal hemispheres, one of which had a surface-gap spark plug in it, threaded in from the back side. The switch hemispheres were held a fixed distance apart in a chamber that could be slightly pressurized (raising the pressure raises the self-breakdown voltage). The big capacitor bank, load, and switch hemispheres were connected in series with the load. Firing the spark plug would ionize the gas between the hemispheres, and an arc would form between them... which would dump a few hundred kiloamp pulse from the capacitor bank to the load. I'm very glad to have escaped that project with all my fingers, toes, and skin intact. :-p
9:14 I don't see an issue here he just incorrectly connected the clamp on the battery, and it was loose, so it created a bad connection. There is a specific tool called a battery drop tester that draws a huge amount of current for a short amount of time to test the battery
If you don't have a grounding wrist band your best choice is minimal clothing to minimize static charge and touching something grounded from time to time to discharge yourself, the wristband just prevents any buildup to be safer but it's still doable without it.
I used to resell old computer parts. Much of the SD-RAM was old and had dirty contacts, so I cleaned them using an eraser. Then I put them into my test bench PCs, and ran MemTest to ensure they were OK before putting them up for sale. During summer, I got a lot more failures! I finally worked out that rubbing briskly with plastic onto the memory chips while wearing rubber throngs (flip-flops) made my body into a nice little static arc generator 😏😂
The nail in the cable is a common practice. It’s called spiking a cable. In the US it’s done remotely with a device that drives the nail on it now it’s not uncommon to use a remote cable cutter. They do it because so many times cables were though to be turned off.
13:37, as someone said that anime is Serial Experiments Lain, from 1998, she's working at a massive computer she got to replace her older one, iirc she was adding a processor upgrade and yes, the thing with the clothes & ESD is a real thing after all, never happened to me... yet
I still wouldn't suggest working with high voltage with your clothes off - that's how you directly go from Serial Experiments Lain to Haibane Renmei...
The way he looms in the background with his hand up while using the "magic wand" makes me wonder if it even is plugged in to any sort of a power source, or if it's just him casting a spell
13:50 "don't peek into the factory thinking you'll see something interesting." B-b-but what if I find the process of manufacturing computers interesting?
5:41; The arc creates a bigger flash as a flashover which is a discharge from conduction to give off power from wires, transformers, or other electrical equipments.
I was working on a construction site once. Basically, owner of the shop on the street we were working on disregarded safety standards and placed a power cable half a meter underground. So, when our excavator was digging some nice hole in a ground we got quite an explosion 😁
I love your content, informative, educational, humor and just plain easy to be around in person, if ever given the chance. You make accidental shocks look accidental but knowing what you understand with Electrical conductivity.
The hammer clip brought back nightmares, just last week I plugged a wire in and was measuring it to length for an outside light, forgot it was plugged in and BANG.. thank god for fuse boxes here in the UK and thankyou me for using cutters with insulated handles.. the breaker popped and I didn’t at all get a shock!
The thing you created with the transformer is kinda like how relays work. The current is loaded through the switch but it isn’t activated (two wires not touching) and then the coil is powered through a switch or a knob and the energy induced through the coil pulls the switch closed using electro magnet. Not necessarily what you made but similar
Your test of the USB chargers plugged into each other reminds me of this one genius in my high school physics class. We had the lab power supplies out to test voltage drops across resistors or something, and this curious fellow decided he needed to find out what would happen if he took the DC probes and shoved them into the the free AC socket. What happened was he ended up in the hospital, and we never got to finish our lab...
Hitting the cable with an axe was their version of spiking. Not a way that I would try but there are tools that are designed to do this remotely. It is how you verify a cable is dead before you work on it. Turning off the breaker isn’t enough when you have half a mile of underground cable.
They show you in their class because they grew up with you bud. ... I was 15 in 2007. "we all" grew up with you. Thanks for being online so long my friend. It's been a journey so far.
OMG YES! The car battery vid at 9:00 - that was Russell Coight from an early 2000's TV show "All Aussie Adventures" and he is my spirit animal. You should see if you can find the show online, the humour is right up your alley ;)
8:15 USB-C also has two pins for bus power, so maybe it won't even matter? -The power will be sent from pin SBU1 to SBU2 and the other way around or something, perhaps?- Nope, seems like i'm wrong.
At 10:45 in, the porch light in our horse does that! As well as a couple other lights and outlets. For what ever reason our front porch light won't work unless anything is plugged into an outlet on the other side of the wall. Even then we still have to smack the wall to get it to work sometimes. This house is built in 1980 in Florida, in the early 80's there were very questionable electrician practices, for example using aluminum wire instead of copper, which is actually illegal here now to use aluminum wiring.
That's exactly how caméra flashes work. There is a large 330V cap that gets dumped across the xénon flashbulb, but it's not enough to flash over by itself. It's either triggered by a third électrode hooked up over the glass tube that creates local ionisation, or by dumping another 25KV low power cap to strike it. CFLs work in the same way too, they use the inductive kickback from the ballast (HV low power) to strike a high power mains voltage arc inside the bulb.
i want to see medhi use a flame for rectification. then some iron pyrite. in fact i would love to see him make a crystal set using a cat's whisker arrangement.
12:44 *And* the person working on the wires physically locks the breaker open using some sort of lock out/tag out system. Don't let someone else flipping a switch kill you. When igniters are inserted into solid rocket motors for space launches, the person that does all this wears *every* arming key around their neck so that no one can kill them by turning a key.
As an Aussie, it makes me unbelievably happy to see ElectroBOOM react to a scene from _All Aussie Adventures._ A bushie, by the way, is a person who lives in the bush and/or the outback - that is they live in rural and remote areas of the country.
Russell Coight is kind of the Aussie version of Electroboom. Well, he would be except that Australia doesn't really exist. (I came here after watching SciManDan).
FYI: you showed a clip from "All Aussie Adventures" which is a mockumentary from Australia. The main character is "Russel Coight" who is a walking disaster but is meant to be an expert at bushcraft. The "bushie" comment is just referring to being a "bushman", someone who can thrive on their own in the Aussie outback.
E-Boom ... I almost spit out my coffee with your "living under a rock" comment. LOL. BTW, when I learned Electronics, we called a Full Bridge rectifier circuit a Full Wave Bridge rectifier circuit. When did the name change? Keep those hilarious videos coming!
Mehdi. The four wheel drive blowing up is from an Aussie comedy called "All Aussie Adventures". Comedian Glenn Robbins played Russell Coight. Who was a survival and wildlife expert who charts his disastrous travels through Australia. It was a very funny show and hugely popular here in Australia.
Now I want to build an arc computer (use arcs in place of transistors). No clue if that'd work, and it'd certainly be very power inefficient, but it'd be very cool to watch if it did work.
@@soranuareane Quite different. Vacuum tubes use vacuum, arcing happens in not-vacuum. Arc logic gates like here, using current that can toggle more current (normally closed) would be an interesting project. Vacuum tubes impede current if voltage is applied on the grid (normally open).
Hahaha hilarious when you said people working in computer manufacturing are naked, i work in a semiconductor factory and we wear complete ESD overalls, shoes, gloves to conduct charges to the conductive carbon impregnated flooring, basically turning ourselves into a wire haha, also there are ionizers everywhere to neutralize any static to keep air at 0 volts. Love you vids ElectroBOOM ! hi from Malta :P
I want the exact opposite of that environment to exist, where absolutely everything (and everyone) you touch results in static discharges. We can call it "artistic," and give it a name like "How it Feels to Have Social Anxiety," but it's actually just about lighting people up like painful Christmas trees in the dark if they so much as think about touching _anything_ in the room. Can this be done without a wrongful death lawsuit?
The guy trying to start a camp fire with the battery is Russell Coight (played by Glenn Robbins - you might know him from Kath and Kim) from the comedy show "All Aussie Adventures" and is a parody of travel shows like the Leyland Brothers and Bush Tucker Man. In the show anything that can go wrong will go wrong.
All Aussie Adventures, also known as Russell Coight's All Aussie Adventures, is an Australian mockumentary television series that parodies the travel-adventure genre. Comedian Glenn Robbins plays Russell Coight, a survival and wildlife expert who charts his disastrous travels through Australia, spreading misinformation and causing accidents. The series originally ran on Network Ten from 5 August 2001 to 29 September 2002. There was also a 14 November 2004 telemovie, Russell Coight's Celebrity Challenge, which featured minor (fictional) celebrities joining Coight in the outback.
Great fun as always, thanks Mehdi! But... SOME ANIME you say... Serial Experiments Lain is one of the best anime ever created. And technically very accurate! Which makes the whole thing even more traumatizing...
This technique is used to simmer flash lamps in high power lasers. It avoids misfires and burns the electrodes evenly. Also used to fire off high current and voltage pulses through stuff.
I'm currently in the few days/weeks between exams and regular lecture time at Uni and so I started to relax by watching all of Latity yesterday, was done with all of them and literally thought: "I wish he would upload a new one" Guess that wish came true! 😃
The guy with the hammer reminds me. On a US Naval station in the Philippines, shipyard workers were stealing copper wire from the high power grid lines. Except once, they forgot to disconnect power. All the officials found the next day was the damaged frame from the hacksaw and nothing else.
I've worked in an environment where you needed to be grounded. You put on special shoes with a strap in your sock. Then, you test the conductivity on a plate. If you did it right, the door opened and you could go in. The whole floor was ground.

The current is loaded through the switch but it isn’t activated (two wires not touching) and then the coil is powered through a switch or a knob and the energy induced through the coil pulls the switch closed using electro magnet. Not necessarily what you made but similar
Your test of the USB chargers plugged into each other reminds me of this one genius in my high school physics class. We had the lab power supplies out to test voltage drops across resistors or something, and this curious fellow decided he needed to find out what would happen if he took the DC probes and shoved them into the the free AC socket.
What happened was he ended up in the hospital, and we never got to finish our lab...
Thanks Mehdi for making these videos, I love them!
4:25 honestly your 1million sub video is very educational, pain is a great master after all
10:51 "Pierdolone" is a swear word too, just a notice for the future
what does it mean?
@@tanker234.2it depends on the context, but in this context it means "fucking"
Thanks!
Jebane too
9:38; Mehdi, thanks for proving on this clip as an electrical advice.
im never gonna set foot in a ford again /s
I mean, that’s already good advice…
Man you don't gotta use tone indicators, it's youtube not twitter after all
My dad has a ford torris 2010
@@Guestgamesbacon you mean Taurus?
Tone indicators are for redditors
Hitting the cable with an axe was their version of spiking. Not a way that I would try but there are tools that are designed to do this remotely. It is how you verify a cable is dead before you work on it. Turning off the breaker isn’t enough when you have half a mile of underground cable.
13:21 true electric enthusiasts enjoy it too
They show you in their class because they grew up with you bud.
... I was 15 in 2007.
"we all" grew up with you.
Thanks for being online so long my friend. It's been a journey so far.
10:46 tbh this whole video should be beeped out 😁
typical polish videos 😂
no cause this is normal worlds (in poland)
9:00 ... Russell Coight's All-Aussie Adventures! I'd completely forgotten about it. That show was bloody hilarious ... 😂
13:45 you'll still see something interesting it just wont be naked people xD
OMG YES! The car battery vid at 9:00 - that was Russell Coight from an early 2000's TV show "All Aussie Adventures" and he is my spirit animal. You should see if you can find the show online, the humour is right up your alley ;)
8:15 USB-C also has two pins for bus power, so maybe it won't even matter?
-The power will be sent from pin SBU1 to SBU2 and the other way around or something, perhaps?-
Nope, seems like i'm wrong.
At 10:45 in, the porch light in our horse does that! As well as a couple other lights and outlets. For what ever reason our front porch light won't work unless anything is plugged into an outlet on the other side of the wall. Even then we still have to smack the wall to get it to work sometimes. This house is built in 1980 in Florida, in the early 80's there were very questionable electrician practices, for example using aluminum wire instead of copper, which is actually illegal here now to use aluminum wiring.
10:55 Welcome to the Polish community Mehdi, you are now an official Pole

That's exactly how caméra flashes work.
There is a large 330V cap that gets dumped across the xénon flashbulb, but it's not enough to flash over by itself.
It's either triggered by a third électrode hooked up over the glass tube that creates local ionisation, or by dumping another 25KV low power cap to strike it.
CFLs work in the same way too, they use the inductive kickback from the ballast (HV low power) to strike a high power mains voltage arc inside the bulb.
@2:25 Yeah, what did happen? I was looking away and shielding my eyes because you were plugging something in, Mehdi😅😆
I just went through the MOS school for Motor-T mechanic in the USMC and they played some of your videos for our electronics and electrical classes
1:07 if only Ford would actually follow that advice...
They do tho.
Oh, my heart. When you plugged those chargers into themselves, I was not expecting that jump scare!
i want to see medhi use a flame for rectification. then some iron pyrite. in fact i would love to see him make a crystal set using a cat's whisker arrangement.
12:44 *And* the person working on the wires physically locks the breaker open using some sort of lock out/tag out system. Don't let someone else flipping a switch kill you. When igniters are inserted into solid rocket motors for space launches, the person that does all this wears *every* arming key around their neck so that no one can kill them by turning a key.
0:37 "Ow. I just bit my tongue. Ow."
1:35 some of those arcs were making it really close to the far end of the crane bucket
As an Aussie, it makes me unbelievably happy to see ElectroBOOM react to a scene from _All Aussie Adventures._
A bushie, by the way, is a person who lives in the bush and/or the outback - that is they live in rural and remote areas of the country.
Russell Coight is kind of the Aussie version of Electroboom. Well, he would be except that Australia doesn't really exist.
(I came here after watching SciManDan).
13:32 LETS ALL LOVE LAIN!!!
Present day
@@ryujinkondoragon present time
Editing on point as always. Great video!
i did not know about initial arc vs formed arc. that was cool. I was an electrician in the service for 8 years. no one told us that...
FYI: you showed a clip from "All Aussie Adventures" which is a mockumentary from Australia. The main character is "Russel Coight" who is a walking disaster but is meant to be an expert at bushcraft. The "bushie" comment is just referring to being a "bushman", someone who can thrive on their own in the Aussie outback.
6:14 it’s a high voltage transitor
6:04 It is used in lightning arresters to prevent the thunder to go through sensitive equipments
E-Boom ... I almost spit out my coffee with your "living under a rock" comment. LOL. BTW, when I learned Electronics, we called a Full Bridge rectifier circuit a Full Wave Bridge rectifier circuit. When did the name change? Keep those hilarious videos coming!
No name change. Full wave bridge rectifier is still the official, technically correct term. It's just common to abbreviate it. :)
@@jlp1528 Thank You!
Mehdi. The four wheel drive blowing up is from an Aussie comedy called "All Aussie Adventures". Comedian Glenn Robbins played Russell Coight. Who was a survival and wildlife expert who charts his disastrous travels through Australia. It was a very funny show and hugely popular here in Australia.
Now I want to build an arc computer (use arcs in place of transistors). No clue if that'd work, and it'd certainly be very power inefficient, but it'd be very cool to watch if it did work.
You just discovered the working principle behind vacuum tubes. Seriously, that's how they work.
i hope it works better than arc video cards!
@@soranuareane like vacuum tubes without the vacuum
@@soranuareane Quite different. Vacuum tubes use vacuum, arcing happens in not-vacuum.
Arc logic gates like here, using current that can toggle more current (normally closed) would be an interesting project. Vacuum tubes impede current if voltage is applied on the grid (normally open).
Arch... computer...?so you want to run linux? :P
"as you know, those microwave energies cook food from the inside", Oh Medhi, you might want to check into that one.
Hahaha hilarious when you said people working in computer manufacturing are naked, i work in a semiconductor factory and we wear complete ESD overalls, shoes, gloves to conduct charges to the conductive carbon impregnated flooring, basically turning ourselves into a wire haha, also there are ionizers everywhere to neutralize any static to keep air at 0 volts. Love you vids ElectroBOOM ! hi from Malta :P
Ionizers to keep air neutral? How does that work
@@MrCh0o If air is ionized then it conducts static away to ground. Static can accumulate on isolators in normal air only because it conducts poorly.
I want the exact opposite of that environment to exist, where absolutely everything (and everyone) you touch results in static discharges. We can call it "artistic," and give it a name like "How it Feels to Have Social Anxiety," but it's actually just about lighting people up like painful Christmas trees in the dark if they so much as think about touching _anything_ in the room. Can this be done without a wrongful death lawsuit?
you ever bumped into a fat swedish man in malta that goes by anomaly?
6:00 a great demonstration of "flash-over"
The guy trying to start a camp fire with the battery is Russell Coight (played by Glenn Robbins - you might know him from Kath and Kim) from the comedy show "All Aussie Adventures" and is a parody of travel shows like the Leyland Brothers and Bush Tucker Man. In the show anything that can go wrong will go wrong.
I have learned a lot of things from you. So huge thanks 👍
Just what I needed today! Love the content
All Aussie Adventures, also known as Russell Coight's All Aussie Adventures, is an Australian mockumentary television series that parodies the travel-adventure genre. Comedian Glenn Robbins plays Russell Coight, a survival and wildlife expert who charts his disastrous travels through Australia, spreading misinformation and causing accidents. The series originally ran on Network Ten from 5 August 2001 to 29 September 2002. There was also a 14 November 2004 telemovie, Russell Coight's Celebrity Challenge, which featured minor (fictional) celebrities joining Coight in the outback.
Great fun as always, thanks Mehdi!
But... SOME ANIME you say... Serial Experiments Lain is one of the best anime ever created. And technically very accurate! Which makes the whole thing even more traumatizing...
I have to go watch it now!
@Don't Read My Profile Picture ok.
@@ElectroBOOM The idea of Mehdi watching Serial Experiments is not something I thought my brain would incur today
This technique is used to simmer flash lamps in high power lasers. It avoids misfires and burns the electrodes evenly. Also used to fire off high current and voltage pulses through stuff.
I'm currently in the few days/weeks between exams and regular lecture time at Uni and so I started to relax by watching all of Latity yesterday, was done with all of them and literally thought: "I wish he would upload a new one"
Guess that wish came true! 😃
I love how you beeped out all the Kurwas, but not the 90% of different curse words he screamed
8:24 I have tryed that with power bank
12:10 wait a DAMN MINUTE. THERE'S CRUNCHYROLL ON HIS FAV. BAR!
Somehow Mehdi managed to look 10 years older at 6:53 and the outtake XD

The guy with the hammer reminds me. On a US Naval station in the Philippines, shipyard workers were stealing copper wire from the high power grid lines. Except once, they forgot to disconnect power. All the officials found the next day was the damaged frame from the hacksaw and nothing else.
W końcu Polski akcent w filmie 🙂

I've worked in an environment where you needed to be grounded. You put on special shoes with a strap in your sock. Then, you test the conductivity on a plate. If you did it right, the door opened and you could go in. The whole floor was ground.
4:56 Something definitely arced here, but I don't think it was electricity...
lol
