Naa man.These thugs will live on after killing 'the tomorrow's engineers'
At a random electronic store, an eight year old girl next to me was buying enameled wire and soldering kit after referring to a similar video.She didn't even know ohm's law when I asked her. What if people like her, see this?

When I was working in Dubai, we lost a subcontractor to an earth fault on a generator. We shut the company down for 3 days while we all mourned the loss and supported those that needed it. The response from his immediate superior was "We have billion of them, we'll get you another one".

To quote Brad Majors : "Yes, life's pretty cheap to that type".

What to do?

There's a lot of people that work with exposed mains and even HV out there. But yeah, there are some that know exactly what they're doing. This thing just looks like crap though. I mean, if you're going to build something dodgy for an experiment, at least don't publish it as some sort of tutorial. :palm: Not even watching this as logged in (don't want more suggestions).

In that case, I should make "How to deadbug tube circuits". >:D

2:15 - touches the green wire.  :palm:

This specific video needs to be reported as dangerous, but its a slippery slope.  Where do you draw the line?   If Youtube were to ban all apparently electrically unsafe videos, it would gut most of Big Clive's content or even force him off Youtube, and similarly for many other scientific, technical and EE/EEE vBloggers.  OTOH at least there'd be fewer inanities from ElectroBOOM et al.

Youtube's ONLY interests are to acquire as much popular video content as possible to support their advertising platform without significant risk of loosing a major lawsuit or outraging mass public opinion.   Don't expect them to 'do the right thing' or even have the faintest idea where to find a consensus on what the 'right thing' actually is.

Any changes Youtube make, *will* be worse than the status quo.  >:D

I once posted a video of how to remove a lawn mower blade using a wrench, hammer and brick.   I was very proud of my technique until a few weeks later when I found a related video that showed that you could lock the blade by inserting a screw driver into a hole and then use the wrench and hammer.  I did remove my video quite soon after.

YouTube should be representative of all people.... stupid ones included.   :-DD

In this video I am going to make transformer less power supply using some Zenor Diode and other components , this transformerless power supply circuit produce multiple volts

So it could be argued that it shouldn't be reported, as this circuit technically does have legitimate application.
But as there is no commentary it's up to personal interpretation.

There are several risks with such a circuit and without any safeguards, it will only take a component failure or a simple mistake for someone to be severely injured ... or worse.

The danger is in how easily things could go south.

...But a couple of things all these videos have going for them are great opening graphics and music that makes it look like they are trying to outdo each other. That doesn't really make up for the sheer lack of knowledge and dangerous design though.

Most these videos look like they are documenting an unsupervised school science fair project gone bad.

There is a similar video, via youtubes recommended related videos, to click on the right hand side.
It seems to originate from the same country.

Most of its comments, are about using the circuit. Very few, actual comment on how dangerous this circuit can be.

The guy in the video below. Is demonstrating that even in the original video (in the first OPs post), apparently dangerous method of using this circuit, can be beaten.
It shows connecting to the mains without using a plug, by jamming in the wires, into the socket (3:53 in video, below)  :palm:

It has been built in an even more exposed way  (fully exposed point to point) :palm:

It is just waiting for someone to walk past and accidentally make contact with it  :palm:

He even demonstrates how to make/mess with it, while it is "LIVE", and touches it for long periods with his hand, while videoing.

tl;dr
Without starting a bad political thread  :palm:
My understanding is that some countries, have very bad safety precautions in general.
E.g. wires jammed straight into mains sockets, etc etc.
Which is generally NOT seen in the west.

He does this from time to time, but there is difference between him and them. In te beginning he puts a lot of warnings, he tells about them, he draws them etc.

The number one cause of this sort of thing is...
Copying something without understanding WHY things were done a certain way, how it was assembled, or what thoughts went into the design.

Does anyone else think the authors of these videos have never gotten an electric shock ? or far more likely, have a blase approach to everything ?

IMO, you are overreacting. Indeed, that type of power supply is NOT safe, and NOT recommended, but it won't kill you more than crossing the street without paying attention.

But witches burn as wood burns, therefore a witch must be made of wood. Wood also floats, as a duck floats, which means if a witch weighs the same as a duck she's a witch and must be burned. The "in case she turns anybody into stone" is purely incidental.

Strangely enough...
I repaired one of these Brush things the other day, it was a BaByliss brand and cost £50 I'm told.
Really poor quality inside and looked like the ones in the video! I was surprised when I was repairing it at how dodgy it looked inside and
wanted to bin it rather than repair it, they have 2x DC motors inside and have really crude rectification and voltage dropping, the one DC motor had sized so ran it up on the bench PSU for a bit with a few amps up it (This is the one that turns the brush) I think she must have jammed it at some point and the brushes had stuck.

As long as the "transformerless", solution is safely inside a case, and doesn't present any kind of safety risk, externally (e.g. unlike some unsafe/dodgy USB chargers, as shown by some of BigCliveDotComs videos). Then, it is NOT too bad.

It is when a beginner/low-end-hobbyist, messes around with these, potentially (excuse the pun) highly dangerous circuits, that people get concerned.

In fairness, it is NOT limited to electronics.

Potentially unsafe youtube videos, can be found, in all sorts of areas. Unlike, in the "old" days, of when things like that would only be usually seen on TV. With the TV company, using "professionals", to ensure that the TV programme, would only show "safe" things and supply any safety warnings as necessary.

These days, youtube videos, can show all sorts of, crazy/unsafe things.
E.g. Youths (seemingly, often Russian), climbing up, apparently hundreds of Metres, WITHOUT any apparent safety equipment, such as safety harnesses.
Then at the top of buildings, precariously, climbing round the top of the building, while only holding on to some dodgy part of it, with one hand.
Such videos, tend to make me sick and/or look away, when I've seen them.

I know what you mean. Some electronic items, are a real mess inside.
These transformerless circuits, are also possibly a fire hazard, especially if they are not fused.
Especially when the wrong type of capacitor is used.

When you do videos where the potential is risk to life and limb if you do it wrong you should put the warning INSIDE the video. Watching that as a link with no EE or electrician knowledge you wouldn't know how dangerous that shit is.

What actually made me cringe is when the guy touches the exposed wires near the end. Best case you might get a shock if you short it to ground. Worst case you end up dead.

On the other hand, I think people are too uptight about this sort of thing. When I was a kid I had an old book of electrical experiments which was clearly aimed at kids. One of them was how to make an electric hotdog cooker that consisted of a board with two nails through it, connected directly to a mains cord. I built one when I was probably 8 and used it a few times, the hotdogs tasted terrible but it was fun, and obviously I never died. Then at some point within my lifetime it seems everybody has gone hysterical about safety and tries to shield and protect everybody from everything that could possibly hurt them.

I feel old saying this but when I was a kid we did stupid stuff sometimes and learned not to do it again. Lots of people have stuck their finger in a light socket or poked a metal object in an outlet, most live to tell the tale and few try it more than once.

Things were a lot harder to "Play" with especially with Type G sockets, we also have double insulated cables and don't use that twin core "lamp" cord (I think that's what it's called in the US)
220-240 or (250v+ in some areas) is a lot more dangerous. <100V can kill too.

Not sure if it was the same in other parts of the world but throughout school we were warned about the dangers of electricity and forced to watch government educational videos on all different topics.
Some were on low voltage electricity (240v) and other videos about High voltage electricity from substations and the national grid.

In fact I recall watching TV as a child and often there were safety videos about electricity, overloading sockets, extension leads all kinds of things.
Certainly scared me as a child to mess around with anything electrical.

Has anyone else reported this video?

The carbon arc was only there as a source of negative resistance, what I was really trying for was a carrier wave in the LW band using an electric fire as a ballast, tank coil wound on the legs of a chair, and a tuning cap made of two foil covered boxes that could be slid inside each other.  I got in trouble for that one, but mainly for using dads whisky as a source of alcohol to decompose to get hydrogen in the Paulsen arc housed in a couple of biscuit tins (Hey the stuff tasted awful to me, I figured I was doing him a favour).

Yep, I was the kid out in the thunderstorm with a kite and the key (Underwhelming, modern cordage is depressingly high resistance even when wet).

So, yea we probably do bet a bit overly worried about this stuff, but back then I was getting it from books that usually at least discussed the fact that this stuff could hurt you, youtube often fails at that, or (in some ways worse) does it sort of right but fails to explain that the nitration must be done slowly, or that the supply is not isolated, you know the little things that matter.

Some were on low voltage electricity (240v) and other videos about High voltage electricity from substations and the national grid.
I remember those, they were a great source of ideas for things to try out on a wet Sunday afternoon.

Love that story, sounded a really interesting experiment!
I remember building crystal radios and remember putting the earpiece directly on a water pipe and hearing a radio station, blew my little mind.

My dad taught me to Arc and Mig weld as a kid, I was warned not to look at the Arc but did I listen, I didn't do it again after getting arc eye!

I tried my hand at making thermite with a 12v car battery charger, a nail and my dads headshell off his record player (magnesium)
when I was younger with encouragement from my friends. That didn't go down too well!

There are several people who make paulsens in their garage/shed. More dangerous than you some guy had it on his messy desk with exposed wiring, what looked like moonshine still parts for fuel, and flammable solids (rags and wood and whatnot) and liquids (paints, paint thinner, gasoline) everywhere. If that went up it would be a hell of a whoosh.

I worry that people are becoming too conditioned to things being safe, relying on protective measures and warnings on everything to warn against any possible hazard. It's more useful IMO to hammer in at an early age that certain things are dangerous and how to recognize risks and reduce the chance of becoming a statistic. Electricity can electrocute you, water can drown you. Sharp objects can cut you, power tools can slice bits of you off, hot objects can burn you, falling  from high places can kill you. Learning early on how to recognize and avoid dangers on a larger scale is better than trying to shield everybody from everything on a case by case basis.

I've seen some pretty stupid youtube videos with people experimenting with 1kW magnetrons and an open 4kV supply on the bench. Darwin award candidates for sure. Luckily they haven't go a clue about impedance matching, but still, definately Darwin award candidates for sure. You could even big it up a little bit "Free energy over unity microwave Tesla energy transfer device"...so that's why ubeam didn't work. But seriously, high voltage physics experiments and apparatus have been published in books for kids for a long time, maybe not so much now, but there were always safety warnings published alongside the construction notes or at the beginning of the book. If somebody gets killed the ultimate responsibility falls on YouTube and maybe not the content creator. LIke Mr Carlson says..."If you're playing along at home...

BigCliveDotCom, at least uses a proper mains block device (Quicktest), designed for rapid mains connections.

Yeah, but unlike those Darwin award candidates, BigClive is an actual electrician. So he knows well what to not do and how to do things safely.

When you do videos where the potential is risk to life and limb if you do it wrong you should put the warning INSIDE the video. Watching that as a link with no EE or electrician knowledge you wouldn't know how dangerous that shit is.

What actually made me cringe is when the guy touches the exposed wires near the end. Best case you might get a shock if you short it to ground. Worst case you end up dead.

Have you seen Electroboom's channel  :-DD

He does some crazy stunts but he is an EE, AFAIK, and most of his stuff is carefully staged so that he doesn't get hurt. He does know what he is doing, despite all those sparky/smoky/KABOOM! hijinks.

Electroboom is a proper engineer and he knows exactly what he's doing. He's also showing the many things that can go wrong, albeit in a humorous fashion. If anything he's advertising that you should be on your toes at all times and that getting hurt is easy.

No, the ultimate responsibility falls on the individual who did whatever killed them or somebody else. If I tell you to jump off a cliff and you do it is that my fault? If you tell me to drink a bottle of rat poison, is it your fault if I'm stupid enough to do it and die? Of course not, each of us has the individual responsibility to look out for our own safety. It shouldn't be necessary to put railings around every high place and warning labels on everything that could possibly hurt anyone if misused. Stupid people do stupid things everywhere, blindly doing something just because someone else did it and didn't explicitly warn you not to, that's on you.

Which one was that? I hope not the one where the Jacob's ladder fell on him.

Yes, and he grabbed both wires, connected to a microwave oven transformer.

I suspect that one was both staged and there was quite a bit of the "sparking" added in post-production.

Had he really grabbed both poles of the transformer connected to mains (as the video purported to do), I don't think we would have seen more videos of him afterwards. ~4kV across the chest from a high current capable source is no peanuts.
