The next part - what's inside the module in resin:
• Stun gun high voltage ...
Today, let's take a look inside a small cheap dodgy Chinese stun gun. It's a WS-618 type self-defensive flashlight. I've partially drawn the schematic of it. The rest of the schematic inside of the high voltage module in a resin will hopefully be reverse engineered in the second part.

But as always, don't overdo it, or your eyebrows might grow together. ;)
yep, said the one that touch Microwave Oven transformer high voltage output
@@razhterize That MOT accident was really scary. Fortunately he had flimsy jumper wires with crocodile clips and a lot of luck.
@@zvpunry1971 Well for 500mA if you can let go in 200 milliseconds you will be completely fine.A MOT can actually supply more than 1-2A so you can probably survive it if you can let go in 50-100mS.
@@zvpunry1971 still not sure if that was real. The should be dead
@@mernok2001 There is a phase of the cardiac cycle at the end of the contraction where an electric shock (of a few milliseconds) may induce ventricular fibrillation which causes death if it isn't stopped (which is done with another shock from a defibrillator). Another way high voltage may kill you is, that it easily breaks the relatively high resistance of the skin and actually allows high currents to flow and thereby cause internal burns. These internal burns may release enough toxic substances that they may overwhelm the whole organism and may cause death. A problem is, that those accidents often leave just small mark on the surface and may be misjudged as not so bad.
Even more Salt?
LMAO
Yes
ARR YIU CREIZYYY?
🤣🤣
The room is vibraiteeeenngg
You can remove the epoxy without damaging circuit by putting it in acetone for few days.
@Luiz Gonçalves Would sodium hypochlorite or hydrogen peroxide do anything?
@Luiz Gonçalves Maybe it can be dissolved by boiling in gasoline?
It's just a joule their circuit in there
That "OPEN" switch looks super flimsy, and it doesn't even have a guard mechanism, so you might accidentally activate it in your pocket. That's quite unsafe.
It's syooooper dodgey!
Well, it is a "self defense flashlight". It defends itself against anyone, even the one carrying it.
What does GirlfriendGoneWild use her stun gun for? :p
of course training BoyfriendGoneWild for the next high voltage thing he's gonna do
Maybe rectifying Danyk's diode

6:25 Next Moment: His girlfriend bring Tesla Coil as self defense
Excellent video, I always wondered when does DiodeGoneWild come with a video regarding tasers. Today, my friend has release a video about this topic.
Perfect timing.
The big one is the real thing. The output is HVAC directly from the secondary winding of the HV transformer. It can knock down a bull. It is pretty much like an automotive ignition coil, but the primary is pulsed with about 1000V from a capacitor discharge through a spark gap, making the output dangerously high (like the old HE ignition system).
The small one is a toy. It is just an oscillator pulsing some 20KHz to step-up HV-HF transformer and then the output is fed to an HV multiplier. So the output is HVDC instead of HVAC and the noise is because of capacitors discharging. These types of "tasers" are known to just make the attacker angrier, but does nothing to put him/her/it down. At least the loud sound is somewhat scary, but nothing else.
Will be waiting for the next video on it, thanks

What a stunner !
HMM My brain: *What does his gf use the stun gun for hmm?*
My Thoughts: *DiodeGoneWild Kissing His GF and getting shocked*
in the past I bought 3 different ones. The largest guaranteed that it emitted 100,000 KVolts ..... Everyone inside was the same, all with the resin minibox with oscillator and L-C discharge group inside. THEY ARE NOT VALID. that oscillator costs less than 5 euros, it is powered at 3.7 volts and after a use exceeding a minute, inside its box the final stage is shorted for very little heat dissipation. The recharging system as you said is a FRAGATURA, it is not worth 1 euro, you always have the live line inside the stungun ...... The power cable so fine is a good fuse ......
You did a great service, I follow you a lot both you and Elettroboom.
Ascanio
Nice video. And very good comments, congratulations!
Well explained
I have to see the components inside Stun gun module
Oh no the fleshlights keep coming
electirc stun gun fleshlight
Most of those modules rely on being potted to function. They have inadequate separation to function in air without being potted in resin. They would simply arc prematurely before the full voltage is formed and destroy themselves. Not that they totally function IN resin either, and will eventually destroy themselves anyway.
Helpful information
Try using a heat gun on anything with resin or potting compound, sometimes it will melt and other times it gets brittle so you can remove it with a pick and hammer or screwdriver or similar. Sometimes it doesn't work but it's worth a shot since it could let you see the components without destroying them. Maybe also try chemicals like some acids or acetone though they are likely going to damage the components.
I love the super hardcore warnings at the beginning
I have two of them for years both with black button and octagonal glass. First one doesn't charge battery probably via capacitor fail. Second one have burned LED after accidentaly turned on flashlight and stun gun in same time. Charging cable is lost too. I have also one bigger stun gun with flashlight and siren/alarm but battery is gone after long time without charging.
good stuff man =)
Now let see oh now we dont have the dogey charger. Warning keep away from children.
Touches
Well it gives some shocks
Excellent review and disassembling video. I will be waiting for next part. I'm also an engineering RUclipsr.
One thing that should be considered is if these are illegal in your own country. Here in the UK stun guns are classed as firearms. Possession of a non disguised stun gun carries a prison sentence of up to 10 years and possession of a disguised stun gun carries a minimum sentence of 5 years.
Stun guns are legal here. Everybody at least 18 years old (and not insane) can buy and own them. Tasers, on the other hand, are illegal.
Could try the bigclive acetone method to get the potting off the module.
For sure you know that clamp meters don’t show the exact DC current, the cable and the clamp should be exactly at a right angle and you must check by a reference current for very accurate measurements. I have 4 clamp meters and all of them have up to 80% inaccuracies on DC current.
I'm curious as to how long can the flyback (stun gun) module run continuosly before it self destructs if it does. Hook it to a power supply.
Let's all stop for a moment to appreciate on how he has the ability to stick his finger into a stun gun and not get paralysed.
What is the distance between the electrodes? (The electrodes where you can see the arc). Thank you for the Video. Im interestet what is inside the module. I think a hv transformer with driver and some multiplier.
I actually cringed when you held the mains wires to the charging terminals like that
My Garrelfrends StunGun
0:55 Warnings: May cause electric shock, so they admit that their device is dodgy and that it doesn't work all the time.
Hi! It s crazy to charge the battery without a transformer. I bet the ' gun module' is such an auto transformer. So you could get the live on the output.
Well thats a bonus if you tase someone when its being charged.
plz make a video on how to remove those rasin without damaging the components
Wonder what happened if we put the stun gun electrode in tap water, and turn ot on?
3:37 you just broke the world record of electroboom 😂😂
May I know what major you've taken? And what specific subject focuses on electronics like this and other experiments you've done?... im taking computer engineering, I learnt circuit theory and it doesn't seem to teach me much about power converting, ICs etcetera...
2:18 i don't think anyone wants to use this as a fleshlight
Lighting some attacker's flesh... it probably would look wiggly.
The taser is verry dangerous, when it is userd while charging. I like that simple dangerous circiut
i am working on making subtitles (polish) to this video.
The ca is also curious about it!
Please make a zvs from induction cooktop
Cute cat :3
Could you make a video on CRT TV flyback transformers? I think they are very interesting, and rather complicated.
Great video. That looked rather dodgy, those switches were certainly not rated for the current, the 5mm LED was grossly overloaded, and I doubt the batteries would be capacble of 2.2A for very long (as they are quite tiny)
When you do your follow up video please open up the packet of batteries so we can see what the rating of each cell is :) and maybe also run a capacity test using your meter :)
The module looks alot like those modules from ebay or aliexpress. Maybe they are stun gun modules. What else are they?
Could you maybe explain next time, how exactly the capacitor acts as a resistor. Is it the absolute value of the complex impedance?
it is yes, the capacitor only let's a certain amount of current through before being charged to the mains wave voltage and so on and so forth the impedance=1/(2pi×freq×capacitance)
drop down cap doesnt have a bleeder resistor either
If i extended the wire between the spark and the module, would it still work normally?
I have a stun gun with a 9v battery. It doesn't work as well as it used to. Sometimes pulling the trigger does nothing, and when it DOES spark, the spark timing is slower / farther apart. Any thoughts before I try taking it apart? Anyone? Thx in advance.
It even comes with a chainsaw!
The 250v dropper cap is not across the line so it will be okay.
This thing was on his second channel several years ago...
Replace charging circuit with tp4056 board and use a Li-ion battery. Much safer and more convenient USB charging. Unfortunately we aren't allowed such toys in the UK - but all the parts cost less than £10...
1000 year later a nice video Come 😍
That stun gun if u put it near any electronics like remote it will make abnormal or etc
What happens when you try to stun someone with the charger connected?? You both get stunned?
at least if its internal circuit is unsafe, it will only do the taser's job better lol
When it says [ «OPEN ], you know what to do.
Please make a separate video
Hey there! I love your videos but listening them through a headphone is kinda hurtful since the audio comes out only from the left channel, so if you could put your voice in mono it could be x100 better! Thanks and good luck for the future
Sorry but I did not have this problem, I think your headphones are broken :(
"My cat is curious, let's try to open it"??
Don't use that as a fleshlight
Do not plug yourself in
EleCtroBooM + DiodeGoneWilde = FullBridgeRectifier...!
How to test to fake or real ???thks
Why did you multiply by 1.5 ? What is the 1.5 ? How did it come ?
Estimated number. We know the charging isn't 100% efficient, so we make add another 1.5 times to the calculated charging time. The way the NiCd batteries are charging (sort of slowly) we can "overcharge" it without any problems like lithium does.
Did he just say it has a fleshlight?
How old is the big stun gun?
How does those batteries (3.6V) charge using just bridge rectified 230V AC????????
there's a dropping capacitor.
On the topic of the 250V capacitor, I've seen A LOT of 250V rated glass fuses on mains, not just consumer equipment (if it has a fuse, it's a 250V fuse probably 99.9% of the time) but also in industrial control systems, which is ridiculous, you'd expect industrial equipment to have properly rated components, but I've even seen the small 250V fuses on 400V circuits (565V peak) then again, industrial equipment is often overpriced by a lot (like siemens 4GB CF cards going for 10k€ and you can't use a regular card)
250V fuses are rated 250V AC but cant be used even on 120V DC.
Roswaal?
No hatey btw, your videos are great!
Can you use this device for high voltage tesla coil?
Yes you can
I think Jay from plasma channel made video about making a Tesla coil from a stun gun
Please Tell Me The Meaning Of Gucthy
can anyone tell me why this guy's channel doesn't have auto-generated captions anymore? I'm a deaf dude here... so I rely on captions to understand whats said.... unfortunately because there's no captions, I can't watch any of the videos he uploads... I originally subscribed 2 years ago with auto-generated English captions... now? there's none whatsoever, leaving me to try and figure out the video contents myself without any sort of visual aid or captions to tell me what he's saying.
P.S. DGW; I subscribed because of your cat... still subscribed, just not able to watch any of your videos due to no captions being generated by RUclips or Google.
@Acid Trip You are Bad :(
12:00 behold the magical DB107...!
Triple Aaaaaaa battereees 😂
You should heat in on oven. It will melt and you see what's inside. :P
👍👍
“Keep away from the reaching children”
Is it ilegal
What will be output voltage
DC or highfrequancy ac.
It's probably DC. Cheaper stun guns are mostly multipliers.
@@DiodeGoneWild ok
Thanks
your title does sound like "dying wild" 🤣
So you have two options....
Die by robber or by this stun gun... 😂😂
1:12 "it comes also with a fleshlight"
10:52 fast maffs
⚡️👍
After you said that it can be quite unpleasant if you hit it on more sensitive body parts then i said: the balls
I don't know but I hope it's dangerouuuuse. And I hope your cat doesn't learn to use it, of couuuurrrrse,
such a simple circuit but holds 3 years in prison in the uk
What's inside this stun gun module?
Wait for the next video. I'm trying several chemicals to see which one could dissolve the resin.
@@DiodeGoneWild I think bleach or accitone could dissolve the resin but you can give it a try and see what happens ;)Myslím, že bělidlo nebo accitone by mohla rozpustit pryskyřice, ale můžete to zkusit a uvidíme, co se stane :)
4:20 Point to pint soldering in 2020 0_O
Makesure your vibrator and your stun gun are diffent colour
Hello
You can help me please
Vždycky když pustím video tak během úvodních titulek, že vše děláte na vlastní nebezpečí tak si říkám nahlas: "So today let's take a look ....." :-D :-D
Seems 1cm of gap so about 30,000 V. Need 150,000 to really zap an attacker
I would say it depends more on energy stored in the capacitors
@@milanhlavacek6730 A real taser works at only at 3,000V for the main shock, the high voltage is only to create a conductive path. A lower voltage, higher current shock is _much_ more painful. (Yes, I have tried it!)
@@threeMetreJim i think it is called extrernal triggering scheme and it is sometimes used in pulsed lasers still, i think energy still plays most important factor. My uncle got shocked by 1.5kV supply with 0.3J of energy and he jumped up a bit and said it had hurt a lot.
@@null643 Definitely. Just try getting a shock from one of those electric fences designed to keep humans out. Not particularly high voltage, but really hurts. Not something you want to do again. Something like this (8kV no load) www.gallagher.eu/en_gb/mb1000-multi-power-fence-energiser I tried touching one by earthing my hand to one of the metal fence poles, and extending a finger towards the wire - a big, loud zap that hurt, and a white finger end for an hour or two.
but i dont care about the cheap flashlight part, i want to know aboutthe module!
Why you don't buy anything from ali or ebay...
In some videos he disassembled some cheap chinese things from eBay.
Maybe before dismantling the HV module, you might put it on continuous-spark (with a decent battery PSU) to see how long it lasts before burning out. The module in my stungun failed after, I'd guess, 5min of 'normal' use - periods of 5-10secs of sparking - so they seem fairly delicate. FYI, those Ebay 3-7kv transformers that cost just a few $, can KILL an expensive mains power supply if you try to power one from it. I found out that the hard way!!! Always power these from batteries.
