Guy just shoved his finger in a freaking stun gun as testing rod. If I wasn't already subscribed, I would do it again.
I would love to see another troubleshooting/repair video from you. I love your ATX and drill charger repair videos. Some of the best on RUclips! Showing common problems and how to find them.
Do you plan to enhance more the metal detector / treasure finder? Thanks!
you are better than many famous youtuber, you just taught us how things are working unlike other youtubers they make content funny but not understading
Just in time to finish the weekend with a Diode video! Thanks. I was hoping you would try it on yourself 😅
@Cliff Matthews I think ElectroBoom can lick this stuff and still feel nothing by now 😅
He did, he stuck his finger in at 4:14
@@Lawless89 I saw that, but that was not a proper test 😅
The cat was right and wrong at the same time 🙂 "No schematics" -> unsubscribe. But, "cat saying anything" -> subscribe. And "cat saying: no schematics -> unsubscribe" -> ... oscillation between unsubscribe and subscribe until the battery is empty? Thankfully you did give us schematics 😂
...I'm subscribed, only because I watched the video and collapsed the wave function
@@johnwelbourn3811 I'm subbed, I like his cat...
That oscillation is a ghost byproduct of the oscillation that occurs when you strap some toast (buttered side upwards) onto a cat and drop it to the floor.
That was a stunning video.
good job, useful, well explained, & learnable!
1. I love German - ELEKTOSHOCKER!
2. I love the name 'DiodeGoneWild' lol
Fantastic video, great schematic. I had a childish urge to hide behind the sofa when I started watching this video, waiting for the inevitable application of the gadget to live human skin, thankfully only a finger. Your cat has a great sense of humour.btw
I'm planning to test it to my cat
@@omniyambot9876 cursed comment lmao
@@HoorGuvLabs why tho?
@@HoorGuvLabs I've just bought flyback transformer for my ZVS and it would be interesting!
@@omniyambot9876 awesome! Just don't comedy your cat 😂
I’ love the details man thank you so much
Interesting video.
If you use a high capacity discharge LIPO battery and a gas discharge tube as spark gap, you will get a better performance.
Greetings.
16:18 at high frequency the secondary of the first transformer would have very high resistance so the current through it won't be that high, but still I think that swapping the places of the spark gap and the capacitor would be better.
Love your work 👍
I actually didn't realize you had an Instagram! Gonna be interesting to sift through your posts there! Good call too on the oscilloscope thing too, wouldn't wanna fry a scope with the high voltage!
excellent analysis
You should try to power it with a stronger DC source (eg: lab power supply) and then increase voltage to see how far it can go.
I had that happen by accident with a stun-gun module. I was running one off of a bench supply but forgot to ground it and left it floating. The voltage from the corona eventually nuked the pass transistors and it went up to _90_ volts DC. It was very dramatic indeed. Went from some little sparks to literally a tesla coil. Surprisingly it survived it. But still seeing thick-ass 6" sparks come flying out of it was something I will never forget.
@@mysock351C Holy cow! 😳 I bet it was spectacular!
At least it doesn't say 10,000,000 volts. Great video, that is a wild accent you have. Like an Italian version of Big Clive
You can use an empty staple gun to open glued or welded plastic enclosures.
Nice video!
Nice video clip, keep it up, thank you for sharing it :)
@DiodeGoneWild You can't swap air gap and capacitor. Because in this case, flyback rectification current should go via HV transformer primary. And it will badly rectify because of primary inductance.
instead using chip as timer sefty circuit i think they can use micro thermal reset switch (NC ) and thermistor in parllel then in seriese with circuit so thermal switch let current pass through it at starting untill it get hot by transistor and cut the switch and let current pass through thermistor which is in parallel
with thermoset keeping it warm and off for long unless power is off .
Nice video
Danik you can do a teardown with schematics and a fun explanation of an HID ballast for xenon lamp for car?
Hi well explained
Stunning...
good video, very surprised to see a spark gap inside. but cheap shight must have cheap shit in it ; ) i liked the timing board although!! i'd bet the last potted part had another cap and high voltage diode inside it at the end of it also..
Definitely looks better than most chinese models. The German text uses proper german, no weird sentences or mistakes. I didn't read all of it, but it did tell you to use a specific model of battery only, and which way to insert it (you did it correctly at the end).
Glad I'm not the only one using a camera to get single shots on an old oscilloscope, lol.
I like how he sounds like a vampire.
Mulțumesc aceste persoane pentru scheme sunt în pace ionat pentru acest montaj
We need more dodgieee (dodgyyy?) stuff!
Hi Dany, i would like to see a video on modifying a DC-Powersupply, for example an old ATX or bigger server PSU to get a variable voltage output. I know the trick about changing the voltage divider on the feedback circuit but for bigger supplies you need another technique. I think many people would like to know about :-)
Why they use ferrite core in high voltage transformer?why not metal core?
Can this be somehow modified (e.g. by inserting a variac or a stepped autoformer/transformer) to turn it into an ESD test generator? Then the timing circuit could also come in handy for programming various tests. If so, where would you place the stepped transformer?
Easier to just put an adjustable spark gap there.
any recommendation about good Stun Gun design
Please, can you do a teardown with ESP Scorpy max and ESP Power max stun guns?
An interesting video, but why complicate (put a microcontroller) in a primitive device? The gas spark gap is not Epcos, a multivibrator on one transistor, although a multivibrator on two field-effect transistors would be more efficient. Well, battery power will not give a lot of output power.
do the modification you mentioned in last minutes in next video?
Does that Spark really letdown suspect ?
niiiiiiiiiiice as diodegonewild says lol
Link for buy please
somebody please explain why he doesn't get shocked like hell when he touch that ARC?
8:37 god bless your cat 😄
Shockingly surprising
I have my fire extinghuisher ready XD
can you modify?
Great vid!
This stun gun is ABSOLUTELY useless. The cap is a little over 150n @ 2000v. The trigger transformer is very inefficient which results in the output putting out barely 10uC. It does tickle a little and to be fair it does look cool. Shame on whatever company is manufacturing this. A good punch will always be more effective than this piece of crap.
Shocking Dan only makes him more powerful.
Niiiiiiiceeee!
Ideal gas cooker lighter.
DIY Or BUY Hah it feels good when we try it ourselves lol
The cat right y’all
👍
Those sparks looks weak, like a single thin spark.
A proper one should oscillate and have several hot sparks for one spark.
Should be much better if the capacitor was in another way or a "small" on the other side of the spark gap
200kV, it should produce spark 10cm to victims from each electrode like in James Bond movies.
No way the CE marking on that thing is legit
but we can see a "made in EU" on the box :D
@@tristanginod9238 idk if we can trust it... Maybe it means made in Enterprise Union"(; like "China export"
Basically a turbocharged cattle prod.
what country is this
Wow! In 1960 one would have used just 6 transistors, in 1975 a 555 chip and 1 transistor, now it has a microcomputer to do what?
Yet the "business part" has a crappy self-oscillating driver only...
Wtf dude just sticks his finger in it! I'm guessing it hurts more when used on bigger muscle groups?
Transfomer or multiplayer?
He measured low and high resistance so surely transformer.
❗️❗️❗️ And dont forget: We electricians / electronics don't sleep, we just recharge ourselves! 🔌🔋😄😄
When dealing with potted modules... an X ray would be useful.... haven't you got one stored away with your old junk somewhere? ;)
I had the same stun gun and opened it a month ago Hah
I've yet to see a stun gun properly stun anyone. I wonder how many amps and with what kind of pulse shape that would work.
are you volunteering ? you might be right, considering what's required for a taser to do the same job...still, I know from, ah, past experience with hobby work, that those things would still be a decent deterrent, no ?
@@psycronizer Not sure about volunteering, but I did conduct some experiments on myself at some point by driving a high power neon sign transformer with a high power audio amplifier while holding on to the transformer output. That way one can try different voltages, frequencies and pulses quite easily. At some point it does start to hurt quite bad and one gets really tired after getting shocked for a while. Not really recommended as neon sign transformers can kill you. It may be that there is no good way to stun a person with electricity with just two skin electrodes without increasingly high risk of killing them. Still an interesting theoretical question.
Great video, yeah I doubt that a device like this would last for very long. It's also not a good idea to use rechargeable batteries with them, due to the lower voltage (8.4V instead of 9V) and also the high current (over 2A when full?) will permanently damage the battery.
Also, I can't wait for "dangerous usb phone chargers 9"! :)
Good one lol. I made two of these for my daughters cause they live in a sketchy neighborhood lol. I used a proper fly back with no spark gap and it is way more efficient. The spark gap on the electrodes are 3.5 cm. With a good amount of juice lol.also use lithium 18650 batteries with a usb charger and board.
Did you warn them about the legal ramifications if they use them?
@@johncoops6897 no problem here. Their not lethal.
@@melplishka5978 - cool. It's a maximum 11 years jail for just carrying one here in Australia! I checked and found they also illegal in a few of the US States, but not all.
@@johncoops6897 Can you own it at home in Australia?Or was it legal to carry one earlier? Someone on a forum wrote that in the 1960s dynamite was sold in hadrware shops. As Tom from Explosions&Fire said,God bless the 1960s.
@@mernok2001 - In Australia It is illegal to possess or use a Stun Gun or Taser. In my state, the maximum penalty is 14-years imprisonment.
As far as I know It's never been legal, however before specific laws they would have been classed as a "weapon" which is also illegal. Note you can apply for a license to own weapons, but it will not be granted for general public.
Another use of the ferrite core transformer joule thief version for high voltage tiny things like an old mini stroboscopic xenon lamp, bug zapper, fluorescent tube emergency lights and a "stun gun".
High Voltage!!!!!!!!.......
Hummmmm Now we are talking....
What’s the problem with measuring the current with a clamp meter? It’s well below its range... Are you worried about HV getting induced in it because of all the interference?
Yes, heaps for RF will kill the multimeter.
@@johncoops6897 Happened with me when i was doing experiments with a microwave oven magnetron even at low power.
The accent😂😂😂😂
40 K Ohms? what? XD
A tiny Pikachu
Why not to give this silly thing some more juice? Like 12V and limit current, for instance, to 10A... and watch it melts.
What yr did this gun come out,1960s looking huge model. 😅
Stungun will get your self killed because theres no charging incator so you just over charge. The caps or resistor blows out at any time from all the shorting thats going on lol.The best way is just fire it into things not much air fire.I would soldered fishing hooks to turn it into a internal acting air projectile acting like tazer so it can arc inside the guy not the surface pain that wont work most time.I know its illegal to mod these things with fishing hooks but it works better. 😅
This stun gun is not doing 200 hundred thousand volts.its a gimmick. It only doing few 100 mabe couple thousand but never million or 100,000 from the shop.you just build one that dos few 100 thousand true volts.
Theres three spark gaps.theres one inside the gun to jump secondarily and two out front.
TRAN sister everywhere
i unironically like the way you speaaak

Agreed, claiming 200 kV on a stun weapon is like claiming 300 miles for the reception range on a TV antenna. Even when analog TV was a thing and after TV went digital, even the strongest TV signals would fade out within about 100 miles of the transmitter due to our planet's curvature (Yes, flat-earthers, the Earth is actually round like a ball, and not an infinitely large 2D Cartesian plane!). Also, I had a thought while taking a shower within the last few days where an electronics student was building a USB charger to recharge a 2S2P 4680 lithium iron phosphate (LiFePO4) battery pack (9.2 volts @ 18 Ah, ~165 Wh) like those found in the newest Tesla vehicles that powers an Elenco superheterodyne AM/FM radio kit similar to an AM-only kit I have (but for more advanced electronics enthusiasts). In the charger, the character has designed the circuit board along with a close friend of his where the board ends up with several inches of clearance between the primary and secondary sides of the board, enough to fit a series of holes in the isolation for a fan to blow air through the charger so that it can keep the components cool. Also, the transformer uses several layers of Kapton and electrical tape between the primary and secondary windings along with heavy insulation as opposed to only the lacquer on the wires, which as you say, can be as little as a few dozen micrometers. The plug on the charger ends up being grounded along with the adapter that the character has designed to go with it, which ends up making the charger include a Y2 safety capacitor between the sides of the board, along with proper interference suppression and snubber networks. On top of all of this, the charger even comes with a built-in power meter and dummy test load to see if the charger really can deliver 240 watts over USB Type C and 18 watts over USB Type A with RGB backlighting on the USB outlets for improved visibility at night. Besides a thermometer displaying both Celsius and Fahrenheit, this isn't even a complete listing of the features of this charger since overvoltage, overcurrent, and over-temperature protection are obviously mandatory.
Why did I just waste my time reading that incredibly boring and Absolutely pointless rant?
on other body parts😅😁
You are very good teacher to explain every electronic circuit and i thank you for this but you speek too fast and i am loosing you many times
Just owning something like this in the UK would be jail time if you were caught with it, never mind used it on someone, comes under the same rules as firearms, keeping them out of the hands of the people, just in case we used such tools to revolt against tyrannical governments like what we have at the moment... :P
It can produce high power wide bandwidth RF signal, which could interfere with implants in some third person who was just passing nearby.
@@iIiWARHEADiIi - So it could be used to deactivate the "Cureena Veiroos" implants? No wonder governments want to ban them 😂
Definitely criminal offence to carry in Australia too. I believe that the maximum penalty is 14-years imprisonment.
[(section 7(1) of the Weapons Prohibition Act 1998 (NSW)]
BigClive said they cant have guns because they would shoot all politicians and they also cant have stun guns because its illegal to defend yourself.
Lol people can build their own. What are they gonna do? Ban transformers and capacitors?
4:13 Looks like POS
Yes not so powerful! Where was the scream of pain?!
doddggyy
That is so bad stun gun
shitty design. They could have made the small board a fixed frequency driver and have very much better efficiency. In fact they could have used a MOSFET and got even better efficiency. Incompetent "engineer" must have stolen the design.
