1:14 Scared the shit out of me. I thought my graphics card was dying.

Advice on your soldering technique: use a flat tip on your 'iron' when soldering to a piece of metal larger than that found on a circuit board, like the electrical contact on the micro switch. Also heat the bottom side (flat) of the contact metal, then apply the solder from the opposite side (a bit of liquid flux applied to the contact before touching the iron would be helpful, even if your solder is 'eutectic' and rosin core). Allow the solder to melt and flow to the iron on the other side. The desired amount of solder will not form a ball, only a thin skin on the contact surface then a slightly thicker 'blob-ette where the wire joins the contact. Less (solder) is more (a better) connection.

it's sad this flies way over most people's heads. your videos really deserve more views. brilliant

This raises me two questions... 1. How much of a threat is this device? 2. How long does the battery last?

Hey guys! I highly recommend you look at the instructables I made linked in the description, I changed the design a bit to keep it from overloading!

I decided it needed more volts so I used my car battery ... Tased my Yorkie now he's a freaking Pikachu

I love watching videos on diy electric devices like this

Dude, your a genius. Tasers are illegal in Canada and I needed one for a homemade potato gun out of PVC pipes that I'm making. This is a very cheap, but a pretty damn good alternative

Dude your videos are so well explained :). Thank you, helps me alot

Just to answer a few questions about the 400KV boost modules: I've personally bought these a couple times, theyr fun. I even disected one that i acidently killed. First, they actually put out about 30kV Max. You can calculate this by the spark distance. Second, they have a single transistor driving a boost transformer folowed by a voltage multiplier 3x i think, my transistor was labled C3746, a NPN rated 6A 100MHz. The secondary seams to be electrically isolated from the primary. There are 3 HV caps wired in series with a bleader resistor across the whole thing. Thats good for most ppl since they will discharge themselves when not in use to be safer. Now for the info on how easy it is to kill these things: The main HV caps are severly under rated for the job they have to do. Any atemp to let this thing run WITHOUT discharging before the voltage climbs too high WILL damage / destroy the caps, killing the unit. These units are basically built skeliton style, but then encased in epoxy, no actual circuit board in them. Letting them run too long can over heat the internal components and damage them. I would think the most heat sensitive parts would be the transformer windings, the transistor, or the voltage multiplier diodes. Now if your nice to these units, they will give you lots of fun, dont try and bring the leads too far away to get the biggest spark you can, let them spark before the voltage climbs too high, and dont run them too long at a clip. I'd keep the spark about an inch or shorter and the duty cycle under 50%

Hey Keystone! Just wondering, how badly would it affect the booster if the two terminals started apart, but were then brought within arcing distance? Because you said that having the terminals too far apart could damage it

Bro.....you're awesome ur videos are much more detailed

This is how to make a stun gun, not how to make a taser. Tasers are hand held fire arms that fire electric projectiles attached to wires attached to the gun. While stun guns are and hand held devices used for close range electrocution, like melee.

you are by and large the most useful yourtube DIYer i have seen to date. a lot of the stuff i watch and try to do is forging and such, this, however is simple and cheap. a lot of your designs can be easily changed around for a few applications. and again, this is coming from a guy with zero background in electronics. just a hungry mind.

Is it ok to use 9 volts on the converter rated 3v-6v? %100 genuine question! Does it make it more powerful or is it just convenient and works? Or is there another generator I should get?

This is very cool ...Thanks for making this video

Instead of buying a boost converter. Most hobbyists use a relay set as a buzzer. Take the EMP from the coil then through a capacitor/resistor lattice to boost the pulse into the crazy voltages you need.. Others use a flyback transformer from a CFL bulb.

Wow this channel is growing real fast! 20k to 100k in only a few months!!! Your gonna hit 1 mill pretty soon

its really great i,ve built this whit a 700Kv booster and its really effektive (ouch)😖😖

This was a great tutorial can't wait to make it.

I made one of these recently, but the arc was a max of 3 mm. Am I doing something wrong, or is the boost converter just a dud?

The article says the converter is rated for 3-6V input. Is the current draw reducing your battery's voltage enough to put it into that range? Would you use one or rather two LiPo cells as a substitute? Thanks!

Brilliant

its funny because i have made one of those using the same boost converter. but i used some big Heatswring tube over the converter and the button

I suppose if you wanted to make it a little more reliable, you could add a recessed slide switch to act as a safety, then enclose the battery in some kind of housing and leave it attached. That battery could get knocked loose pretty easily in a scuffle in its present state.

Bro you should have way more subs. You make great videos :)

I have a question. I did the same thing but I am not getting as much current. Do you have to hook it up to with the old 9 volt battery terminal exactly like you did in the video?

Hi brother..your videos very well and improving my knowledge.. I have one problem regarding Samsung microwave oven..I found fuse blowout which is in between transformer and capacitor..replaced with new but blowout as soon as start..checked magnetron ok. HV diode shows open ckt on forward and reverse check with digital multimeter.. I increased fuse capacity then I found transformer overheating. Transformer also checked ok.please tell me what's problem..

What type of transparent container could the generator be active inside of? Glass, acrylic, or …? I’m trying to create an opportunity for people to observe the electric bolt. Seeing such a thing in person is amazing!!

dont lay down with this in your pocket ;-;

My converter makes a very wimpy spark almost like a piezoelectric bbq ignition. Is it burned out?

Nice video. Thanks!

hey buddy can you make a video on making how to make the convertor having same performance please

Did you get the switch from an old microwave? I recognize it from when I took one apart.

Does the "Power Converter" that you used in the video also have an input of 3v-6v like the one in your link? I was wondering if a 9v battery would burn out the 3v-6v converter.. Also, did you measure to see what the final output was in terms of voltage and amperage (mA)? I know the converter *says* 400,000v but that's contingent on the input.. If you research stun guns you'll see a lot of conflicting information. They're marketed mostly by advertising the voltage strength, but then supposedly 30,000v is the maximum voltage that can jump across contacts spaced 1cm apart because of "physics" or whatever. Some sources say that its true strength is the microcoulombs: µC, or "charge", other sources say it's the mA, or "current": Below 1 mA Not perceptible 1 mA Threshold of feeling, tingling 5 mA Slight shock. Not painful. The average individual can let go. Involuntary reaction can lead to indirect injuries 6-25 mA (women) Painful shocks. There is a loss of muscle control 9 to 30 mA (men) Freezing current, "can't let go". The person may be thrown away from the power source. An individual cannot let go. The active involuntary reaction can lead to unintentional injuries. 50 to 150 mA Extreme pain. Respiratory arrest. Muscles reactions. Possible Death. 1 to 4.3 A There is fibrillation of the heart. Muscular contraction and nerve damage occur. Likely death. 10 A Cardiac arrest, severe burns. Death is probable So I'm curious to see how this measure up to the real thing

lol. you're SO smart. I thought you were building voltage amp circuits, but I suppose buying it is easier if its cheaper anyways

And thanks for the video it was awesome to make !

Many of the reviews I read about this particular HV Booster is that they don't last very long. i.e. They fail in a short period of time. Has anyone experienced that before?

best tutorial :D thx

Can't wait to use this at school

This channel is so cool

Do the boost converters come wired already, The red & green and the two nice shiny red zappers?

Hey! Cool video! Is there any possiblie way to connect 5 boost converters of 400Kv to make 2000Kv or any other way to connect several boost conectors to get a higher voltage?

What would you use the boost converter for beside an emp or taser?

can you show us how to do the power converter...

Is it possible to make 2 of these and have them discharge from the same wires so 2 boxes 2 batteries but only discharging from 1 set of wires if so which is the safest and most reliable way to wire it thanks in advance - Menz0

could a fluro tube inverter for a laptop work as a boost?

cool stuff

Question: The Step-Up module you used is designed for 3v-6v input, but you clearly used a 9v input. have you had any damage to the module or should we be concerned about the extra voltage? Does the module not have the ability to draw more than 6v out of the battery or something...?

Is there anyway I can make the power converter myself?

hey ,, i bought boost converter from amazon, but i am unable to use it. when i connect 9v battery , nothing happens. what to do? pls help

On the Ebay page says that the power coverter is DC 3V-6V, is there any problem using a 9v battery?

would this provide explosive results if i used a lipo / li-ion battery? i have a spare 18650 battery that i need to do something with, im aware of safety with charging, amp protection, etc.

Hey Keystone, i have a Problem. there is no spark between the wires when i press the button, only when they touch each other is that normal?

what's the different between this, the arc lighter and tesla coil?

Can those modules be used as a high voltage supply?

i did the exact same thing but doesnt have the same desire outcome. just a small spark once in a while when both output end touches one another. please assist

How do I add the heatshrink when the the wires are connected? And soder :\

how does the converter work?

will I feel pain if my both hand are touching a boost converter while it's on?

Great video I just have 2 questions. Is this deadly? and if not have you tried it on your self?

made one , nice

what kind of wire do you use in the start of the vid?

I literally bought the exact same thing with a lithium ion battery and the guy threw in a momentary switch anyway I was wanting a more sturdy set of prongs because if you touch something with your one the wires will move apart and stop working I think thick hollow plastic tubes would work what do you recommend?

I used an 18650 li-ion as it is within the voltage range spec of the unit and can easily supply the 2.3amps that I measured in operation. The 9v battery can't come close to supplying the needed current and will cause the unit to breakdown very quickly if run open circuit. Bad design.

hey dude my country doesnt supply those converters,, whats the replacement ??

Yes

Could that arc be used as a fire starter?

So you just added power and a button to an existing taser? Good job.

Hey, if you or SOMEONE could PLEASE direct me to which boost covertor you bought I would be extremely gratefull, a link to it on amazon would be extremely appreciated

Any way you can show how to make a strong electromagnet? One strong enough to keep a metal door secure or strong enough to life a few hundred pounds?

I feel like it’s been longer than 7 years since I watched this (and your other videos) did you ever have to reupload them? Well anyway, very informative as always, I’m here because I was randomly recommended your pocket emp video and I’m feeling a little nostalgic. Take care, dude!

How long will this device spark for if i keft it on costantly???

check amazon for battery charger that is capable of recharging toss away alkaline batteries. I got one for about $35 including shipping. I get about 20 cycles out of a standard Duracell alkaline.

you can just use 18650 Batteries as well.

I know this is very late compared to when the video uploaded, but when I was finding the parts (cuz this is totally cool) there was only a 700kV in stock on amazon, and i assumed it would work... will it?

If you're in Lancaster county, I'd be interested in some projects

5:29 "this thing is sure to DROP?" or just scare away?

But can you use a tactile switch?

Your comment on Nighthawkinlight brought me here. Great channel! I like the way you narrate and the general feel of everything. You should just work on having a less distracting work surface (like a white or gray table) and a set backdrop. Gotta have that pseudo professionalism.

The ones on ebay say they are rated up to ~7VDC, but you showed it working with 9v. Do they burn out with 9v, or is it still working ok? What do you think the actual maximum input voltage is?

Is possible make a mini jacob's ladder using it?

I like IT! TARS dude.

Nice

How does this DC power converter work?

you think could turn this into a taste glove? couldn't I move the switch to the index finger and the two taser wires to the middle and index finger? of course for that part I'd need to make the taser cords longer. any ideas? I would also have the rest of the parts on the back of the glove.

Where did you buy this boost converter from

what hapend when we connect a 4000v taser in a flyback tv transformer pleas tell me bro how volt is out put?

Could this be used as a power source

sorry what if i use a 3v - 7kv ??? is it still working???

What is the round disk that is taped to the battery?

what amperage comes out of this thing?

Can you make this with an 18650? I would love to see videos about projects that can be powered with 18650 batteries

is their one where you make a boots converter

Can you really get the linked (in description) switch to work? I cant.

Keystonce science, i tried to do but it didnt work, can you help me?

I wonder if you could use a mini airsoft gun to make a barb deploying one?

I have bought one too, is it Good to power it with 9V? Because it ist Named with 3-6 Volts.

I have heard that you can make a taser out of a flash, non-digital camera, those that are disposable. Can one be made out of this kind of camera?

Does it matter what size boost converter?
