- čas přidán 8. 06. 2024
- Hey guys! This time, we make a powerful little pocket-sized rechargeable Stun Gun (Taser).
This is Version II of my Stun Gun, packed down to a cylindrical body, safer contact probes (Not sharp & pointy), easy to recharge now via Micro USB, and a brighter power indicator light for better day-time power indication.
The Stun Gun we make in this video shall not be wrongly used, this is only a self-defense tool and must be used for that purpose only. Do not try it on yourself, animals or any other people just for the "Sake of it".

Most people are stunned when they find out how bad electrician I am
I noticed you used the black epoxy I know as J-B WELD Or J-B KWIK. If this is the case then your electrical short at the terminal base is the epoxy. J-B epoxy has metal filings in it, so the voltage output will travel through it.
The problem is in Australia where It is illegal to defend yourself with any kind of weapon even with a permit. Doesn’t work too well when you have people running through houses and attacking people with weapons just for fun.
Screw the government and screw the system. I have a god given right to protect myself and my family and I will exercise it where necessary. Thankyou for the information
Naturally I take full responsibility for any legal ramifications from building one of these and using it if I choose to.
God speed my friend. You are a hero
Restrictions suck. I am glad my video helped you. Stay safe! Cheers.
This is so amazing project! Loved it 😍
Thank you so much! 😃😍
Hi technocrafts!
Nicely done man! I made one a few years back and all I did was hot glue the transformer and battery holder together and put a US to EU power adapter on top for the prongs lol. Yours is a lot more detailed. 👍 BTW I love how you called out how it does NOT output the claimed 400000 Volts, a lot of other CZcamsrs fall for the false advertising. Great job man
Thank you for your comment, Erik! Haha, you made your's the crude way, pretty cool!
Yes, many fall for believing a little module can deliver a voltage so high where it really outputs a several hundred to a few thousand volts at a minuscule level of current.
Cheers!
heres mine that i made

Wow. Nice stun gun. Good job max 👌👌👌
Thanks a lot! 😊
I want to learn more about electrical systems and this really helps! hoping to make a calculator from scratch soon.
The starting scene looked like an ad for a vape pen or something
Nice work, I love the design I was going to just do a basic one and try 3d print something but the pvc pipe idea looks great think I will try copy your design.
PVC seemed cheap and effective at the time, worked well too! Save on some filament and have a sturdier design 👍
Cheers!
Awesome Work dude!
Thanks, bro! :D
Very good video very informative

Interesting project Max 👍⚡
Thank you! Cheers!
@@MaxImaginationbro...1 to 10 how much does this hurt ? Is it enough to discourage an attacker or will it piss him off even more ?
Hello Max! What an amazing project! I'm wondering if I can use a 4v Lead-acid battery(as I have one). Is that fine?
Hello Vishal.
Thanks for watching!
Sure, a 4V battery will do, anything from 3.7-6V is totally cool to use with the Stun gun module.
Cheers,
Max
@@MaxImagination 😂
But does we can use charging module of lead acid battery
Brilliant,nice one
Thank you! Cheers!
Nice one bro 👍
Thanks, Sahil 😊
Good stun gun, Max

@@7MinutesCreative Hello
@@slyasastech Hi
So cool!!!
🙌✌
i had this same idea but i want to do it with a vape mod box that takes 2 of those batterys
Superb 🙌
Thank you! 🤜🤛☺
Discovered that if you connect the module (load) to the OUT + and Out - on the charging board, the firing will not work very well. I noticed you connect the module in parallel with the battery B+ and B- on the board.
Thanks for noting this!
Hey Max, I’m just a little curious about something…
I see in both your video and your schematic you place the rest of the circuit in parallel with the battery terminals, rather than using the outputs on the TP4056 board itself. Was there a specific reason you chose to do that?
Hi there, Lucas. Interesting you point this out...
I have done this to bypass the charging board's over-discharge protection feature that comes with when connecting the circuit to the OUT+ OUT- terminals. Another viewer found that connecting the rest of the circuit with the OUT terminals resulted in very early circuit cutoff, reducing the stun gun's reliability when one really needs it. Implementing something such as one of those cheap battery voltage level indicators into the side of the stun gun can come in handy, knowing when to recharge the battery.
Hope this makes sense. Be sure to choose wisely on which terminals you connect the circuit to.
As recommended and shown - hooking the circuit up to the same battery terminals of the board will ensure more reliable performance.
Cheers,
Max
Grate vid my friend. BTW, can you tell me where can i find a source of information in more detail about the operation of the transformer and how exactly it works? thank you!
Hi. Thank you! So far, I couldn't fink any specific sites which go into detail about how this Stun Gun's type of module works, though you could check out this site of information about the general practicality of how one works and about the danger - www.tbotech.com/stun-gun.htm
However, I did find this video from DiodeGoneWild explaining the working principle behind the Pulsating High voltage transformer - czcams.com/video/_Zs8nox4QoA/video.html
You may also find this helpful - www.hindawi.com/journals/jece/2020/6525483/

@@MaxImagination Thank you very much!
Would probes from a 125 volt power plug work or does it have to be 220 volts? All the 220 volt power plugs I've found are super expensive while the 125 power plugs aren't.
HI, a 125 volt probe pair should work just fine, I mainly chose the 220V type probes because of their shape. So, no worries on that one! :)
Made the first one and will make this one
So cool to hear! 😍
i make this this is amazing
Nice video bro 🙋♂️
Thanks! 😊
Cool 😎👍 better to make your own then the ones in the store .. they're all cheap .. I don't know why it's so hard to find a well made product these days 🤔
Thanks for watching! Yup, DIY is often the way to go!
China ! 🇨🇳 =💩
Can you make Taser Ring ???
This is wicked 😂
hey man i have a question, shouldnt the wires on the transformer go on somewhere else on the smart chargingboard instead of soldering directly with the battery wires?
Hey there! The input wires of the transformer don't go "directly" to the battery, but through a switch and a push button, yes.
@@MaxImagination ohhh ok I get it now
Nice..
would like to ask the output wires is it both positive or negative ? is it possible to connect 2 pulse generator?
They do in fact have polarity as it is amplified DC voltage! This video shows two connected in series for a bigger zap: czcams.com/video/j8HPp016GOo/video.html
Nice
I wanna make one from a flashlight but I was wondering if I can use metal as material like a old Maglite flashlight or the case must be plastic.
I would use plastic mate, with high voltages come the arcing phenomena where a pathway through the air is taken by the current in jumping to a conducting material (metal), respectfully Max’s advice here is not the best
Thanks y'all for the answers
Hi! Awesome build buddy, just a quick question, is it going to be lethal if used on an arm / leg (far from heart for instance)?
Hi there. Thank you for your comment! It shouldn't be.
@@MaxImagination Thanks!
@@francescogallo1013 No problem :)
Hello. I saw your video. I like that. Moe power bro. Love it
Bro. it possible change capacitor more powerful to weak people specially those rubbers, snatcher. And much capacitor do I buy small capacitor but strong enough to weak or stop him.
Hi there. Thanks for your comment! I don't know what you mean, sorry.
FIRST MAX THNK YOU FOR THE INFORMATION. .IS THWR ANYONE WHO REMEMBERS HOW MANY WINDING TO MAKE A PLAZMA ARC PULSE GENERATOR USING A 9 VOLT BATTERY AND SPARK PLUG I GET A ELECTRIC SHOCK BUT PULSE ARC AND USING A ULTRAISO CAPACITOR FOR THE PURPLE ULTRASONIC ARC
No problem :)
I have no idea about the number of windings in one of those. That would require more calculation...
You can in fact order these high voltage arm modules for cheap.
Cheers
bicycle handle bar grip with finger grooves would be cool and help orient hand position.
Good tip!
Hello Max, new subscriber from brazil here, i have a ask for you, can you make an arc lighter using this project base? can you make an tutorial about it? here i live its very difficult and too expensive to find an arc lighter to buy, please do this
Hi there, yes it's possible with this Stun Gun module. The taser with a narrower gap between the electrodes can simply be used as an arc lighter as well. Simple as that! 😀
Thanks for subbing!
Hey Max, I was wondering where you got the probes because I couldn't find it. But I did find a ground prong that looks like the probe you have so, like do I buy a charger and remove the ground prong because I have no idea what else to do
Hi DnD, I already had these ground-probe looking probes already lying around in my electrical parts box, I wouldn't be too sure exactly where they came from. I'd say regular cable ground probes would do the job fine. I recommend you purchase a "TP4056" single-cell battery charging module for safe recharging of your DIY Stun gun, you can purchase these on online stores such as Amazon.
Hope that helps! 😊
Cheers,
Max
@@MaxImagination okay thank you
Not bad. =)
Hello. I want to make one but more powerful. Would you advise me to put two of these modules or put one with more batteries?
Hi there. I suggest you use two of these HV modules in parallel at the inputs with one battery pack of 7.4V. Cheers.
Mine was not as nice as yours but at least it works. How long does the battery last for you? Thanks
Nice to hear you recreated the project! Cool! My stun gun lasts me a few weeks (I don't stun it that much).
Wanted to ask if the led of required, because buying a single led and resistor just doesn't seem worth the trouble
Hi there. It's not required at all, but it pays having one for peace of mind knowing when the stun gun is off. I'd recommend you salvage one of those 3 or 5mm LEDs from any old appliance. You will most likely find one.
Cheers,
Max.
hey when you use the button does it have the be square? Or can I get a circle one
It can be any shape as long as the button you choose can handle the current.
ALWAYS DE- electtrictize capacitor’s !
ALWAYS have someone with electrical experience assist ALL projects if you don’t know COMPLETELY what you’re working with .
The word is *discharge* not DE-electtrictize.
Is it possible to build this with a potentiometer so that the outout can be turned up and down?
Possible... but you will need more than a potentiometer. I recommend you use a DC-DC converter at the input like the LM2596.
Brother what if I use Power Bank Module T6845-C (5V Step-Up Power Module ) instead of Tp 4056?🤔
That will work too. You can use it and also have it as a power bank combo.
Thanks bro, for response, GOD bless you @@MaxImagination
I am looking forward to trying to make one but im not familiar with anything about physics but im going to give it a try i love these type of gadgets
Best of luck!
hey! i was wondering can like how powerfull the stun gun is be changed like i m planning to make a prototype of the same and i dont want it very powerfull, is there any way to do that?
Hi there! You can use a weaker battery, such as a 3V one with the transformer to get a less powerful stun out of it.
Can you please explain how this works because I have read that these transformers are only usable for ac input and not dc input provided by battery
To put it simply, the high voltage pulsating transformer takes a low voltage DC input and produces a high voltage DC output thanks to a voltage multiplier circuit which uses a specifically timed sequence of capacitors that charge up and build on that voltage + diodes to direct that current to keep building up. Hard to explain, though I hope you get the main idea of how it works.
@@MaxImagination yep and thanks for replying
Most youtubers don't reply. Amazing video
What if we use a bigger battery like a 7.4 volt would the power boost module be able to handle it?
Most likely it will, but not for very long (unless otherwise specified) due to the internal circuitry in most of these failing often above an input of 6V.
very interesting
Thanks for watching!
Will a 3.7V 18650 Battery work with a pulse generator with an Input voltage of 3.7V-7.4V ?
Yes, that battery should work.
I dont know why the spark wont jump from probe to probe, i glued two small metal sticks on tope of each probes and it sort of helped but the spark doesent always jump, like i could click the button and i can hear something but no sparks. Any solution?
Maybe your probes are closer somewhere below resulting in a muffled spark or the probes are too far away from each other. Best thing you can do is angle the tips and move them closer together with a narrower gap.
i use the board as a switch from a disposable vape. find where the actuator for the vape is and touch the contact s and boom touch button taser
That's a much better use of that tech, nice!
Nicely done'dude 👍! One thing: there is no safety apparently so suppose you carry it in your pocket,you can SELF-FRY ,isn't ⚡🤪?
Thanks! The switch at the bottom is the safety feature 👍
The only thing I would change is that safety switch as it could easily be push me personally I used one of the switches that's got the clear rubber box over with the switch inside as these need a bit more pressure to switch between safe and armed but yeah get little project max keep post new vids champ, is there anyway you could make one with 3 batteries
Your very intelligent I am from 🇮🇳india
I appreciate your kindness! Have a good week ✌😁
Hey bro I have 2 questions
Does a 6A switch work and can you show how to wire a switch with an integrated led
Hi there. 6A switch might be a bit overkill for this application, but I'll work. Are you referring to one of these? es.aliexpress.com/i/33003707517.html?gatewayAdapt=glo2esp
Hey man is this actually powerful? Like say if I’m attacked by someone and I stun them will it hurt
Hey there. Yes, for some it may even get them on the ground.
Hello, my battery is the 9900 mAh 18650. Will this cause harm to me if I attempt to touch it?
Hi there. If you power the high voltage module with a battery, it will hurt touching the wires on the other end.
Hey, I wanted to do this by myselfe but I dont know wich cables I should use to extend the range of the LED (How thick etc. they should be) sorry i am new to physics and science stuff in general
Hey there! 32-Gauge insulated electrical wire would be the ideal choice for connecting an LED, anything thicker such as 24 or 20AWG, etc... will also work. Cheers.
@@MaxImagination thank you fir your answer
Nice. But voltage is just voltage. The actual effectiveness of a stun gun is measured in microcoulombs. Any idea how many microcoulombs this puts out?
No idea. I wouldn't have a clue unless I review the project and measure that, somehow...
Nice job 👏
Thanks! 😁
hi its okay to use types c charging board
Yes.
I also love to do different Projects just like you. I did other projects like RC cars, RC aeroplanes, water Tornado, etc.
I would like to get in touch with you.
Fantastic!
Does it worka continuously. I also made one. But stops after few sparks
I do not advise you run it continuously as that may overheat and damage the internal oscillating transistor.
The problem has resolved. I connected directly with battery for output.
Does it have to be a 3,7v battery or can it be any rechargeable battery?
It can be any rechargeable battery up to 12V and no higher. Such as 1-cell, 2-cell, & 3-cell configured batteries. Cheers.
Wonderful
Is it possible to get a list of materials and where to buy them?
Check the links in the description.
How powerful is that (taser)?
And how does the body take that?
Can you give all the materials bro. To buy
Materials can be found linked in the video description.
Awesome 👍. I made one exactly like yours, but it only works twice. The HV component stopped working. I did verified that the HV side open.
Thank you! These cheap HV modules tend to be very sensitive to the input voltage supplied. Try to power your HV module not higher than 6V next time. Cheers.
Bro is there any chance of it blasting?Should we be careful while charging it?
The TP4056 (Lithium cell charging board) automatically stops the battery from overcharging. No need to worry about that.
can I use glue instead of epoxy to hold the probes?
Yup, depending on the glue, it should work.
what if I use 2 3,7v battery in series? or it should be in parallel?
You can as long as your high voltage module is rated for up to 9V. Otherwise, I suggest you stick to running one with a parallel battery pack.
Hey! What's the name of the device u showed in the intro next to the glue gun? This black pen looking thing
Hi there. I believe you're referring to my Soldering Iron 😄

Does it charge by sun?
It can 😃
It can be charged with the DIY solar power bank I made in a previous video
Hi what is best voltage battery to use thanks
Hi. Use a battery between 3-9V. This may vary from transformer to transformer...
Hey max. How to solve the issue of draining the battery?My project drains battery real quick just 5 clicks battery is drained.
Hi, Tarsious. Hmm, that could be due to you using a weak battery on its last legs. Are you using an old battery? What are the battery's specifications?
@@MaxImagination new but cheap baterries. P
@@tarsiousmunalembohol Normally, a battery would last pretty long when used with a stun gun module, that must mean you have really weak batteries. I suggest you try another 3.7V one.
Cheers,
Max
you could 3d print a case, it's a lot easier and will look more professional. Anyway nice job.
Didn't have a 3D printer at the time. Nowadays I would make one 3D printed. Thanks for your comment
I'm using this primarily for self-defense. Is this lethal? If so I want to avoid that.
It's not lethal at this level, but it can take someone down to the ground.
can I have a list of what materials did u use
Please check the description box below.
my battery is getting hot. Am I using wire that is too thin. Its the only thing you didnt list in your list of items to be used.
Hi, Nick. I recommend you use 24 AWG enameled wire. If your battery still overheats then, I suggest you would need to replace it for another battery.
Cheers.
is this safe to use on a person, how much would it hurt?
It made me fall to the ground when I accidentally shocked myself. So on average, it would either make you fall or nearly to the point of falling in shock.
The shocks hurt quite a bit, like getting shocked by a 120VAC power outlet.
does it also work with 3600mAh battery?
Yes
Where did you get the brass probes from????
If I remember correctly, I got them from a set of disassembled outlet plugs.
@@MaxImagination I found the plug with the brass probes on AliExpress for about $2.
Great!
