I watched the first few seconds, paused then went onto ebay.. Remember that old game called Operation? The game of skill and dexterity? Well I'm going to make you more careful in how to play it lol☇
I have the same HV Modlue and I built a small tazer. An important thing to remember about these HV Modules, is to not separate the output wires too far apart or the stored energy cannot jump the wires and end up discharging inside and destroy the module. About 1 " is good.
Hi i want a tazer from one of these but i want 0 risk of it being lethal and know im probaly not going to use it on a person unless i really need to but i dont want it to me lethal and i know this comment was 6 years ago but do i need to put a resistor to lower amps or anything or does the voltage mutiplier do it
@@PIXELCRAFT_HD It will give you a good shock, but it won't damage you unless you have cardiac issues. No resistor needed. This is very low current and high voltage. Much like a dog shock collar. Have fun...
If it's any consolation, I once spent a couple weeks of spare time extremely carefully chipping the potting material off one of these modules. The one I've got uses a voltage tripler at the output of the transformer, but does not have any separate stepup pulse transformer. The sparking you're getting is just the discharging of the final cap of the multiplier. I'll send you some photos 😁
Same where I live. You can buy a 200lbs crossbow with arrows and hunting tips, but you dare not get caught with a slingshot, cause that is considered an illegal weapon.
jaaasgoed The UK government banned privately owned and police monitored pistols that were kept for sporting use (target shooting on registered ranges). The idea was to keep guns away from criminals. Now the criminals have lots of guns. Maybe someone in the government found a ready market. Maybe I am getting old and cynical.
200lbs is not the weight, but the draw-weight. In effect you are putting 200lbs of energy behind the projectile. The traditional English longbow for example had a 100-120lbs draw-weight. You'd have to train to be able to draw the bow back to it's full strength and therefore the most energy goes pushing the projectile. This tends to be true for compound bows rather than the recurve style you see on the Olympics for example. Compounds tend to require enormous physical skill, strength and technique in order to achieve raw power. Recurves tend to ditch that in favour of precision and accuracy. The idea of draw weight though did transfer over to the crossbow, though it's slightly misleading with modern crossbows. Original crossbows required less physical technique as you could hold it down with your foot and pull back the string using both hands. Equally, modern crossbows have all sorts of ratchets and such that aid in drawing back the string. Ultimately, the crossbow became popular because whilst the longbow required massive levels of training and skill to use well, the crossbow could be used by anyone with minimal training and still achieve a fair result.
No, Denis, the idea was to keep guns away from lunatics! Michael Ryan, Thomas Hamilton and Derrick Bird were all law-abiding citizens up until the day they went on double-figure killing sprees, just as how every perpetrator of a mass shooting in the US is a law abiding citizen up until the moment they snap and kill everyone in their school/college/office building.
I have build one of those inside my insect zapper, which is formed like a tennis racket. I also included a spdt switch to select whether it is running on only one single AA battery or if both included cells of the zapper are used. Running at 1.5V the zapper is quiet and only zapps when an insect is near the zapping plate. When run in 3V mode, continuous zapping with loud sparks happens all over the plate, mostly on a few single spots. This build is so much fun to zap things with, as even a short swosh through the air definately takes out every creature near by. You can even clean your bed with it zapping, as a static charge will catch small debree on the metal gates on the tennis racket like plate of this device. Small tapping on the handle will release all partikles. The power consumption is around 1A on both modes, so somewhere between 1.5W and 3W. Even operated with NiMh cells it is working reliable. To get the indicator LED of the zapper running on the single cell mode, i used a energy thief circuit. This allowed me to even change the LED to a high power 5mm ultra bright diode, which adds to the whole experience using the device. I don't regret investing the time this conversion took and would alleays do it again. From the beginning i planned for the inclusion for an ESP8266, which allows for integration in my smarthome. Count zapped things over the year and generate statistics. Through the inclusion of a small mosfet even the following is now reality: Hey Google, kill this fly for me. ...there you go, i activated your insect zapper. Please hold it near the bug which is soon to be gone... I love it!

When we get certified for use of stunguns we have to enjoy the experience of receiving a rather lengthy demonstration of the power, usually resulting in a ear splitting scream usually reserved for scared 6 year old girls or in my case a 300 pound hog screaming like a jet on take off. We have to do this for every modle we may use. I always choose to be the first, because if I watched after the first one I'd be gone and since I'm the Officer In Charge, I have to go through the certification. My best friend shot me with a stungun that fire probes. I was nervous, stunguns had just came out and we got some of the fist made for the Corps. So I'm facing my mate and I hear TAZER TAZER TAZER! He fired, one probe hiit me right on the hip bone, the other dead center in my left nipple. The there was Light, and I knew I was dead. When it was just us Officers they would call me "Proby" we also made him a huge medal that had a cardboard medallion that had a drawing of a nipple with a probe and we called it the "Order of the Nipple"
There is actually more to that, the reason you would be aiming for the base of someone's spine is that for quite a significant portion of the spinal column the nerves will all be bunched together into this thick cable like arrangement with individual isolating layers, but near the base of the spine, the nerve bundles that handle operations of your legs and everything close to them split back into separated wires that then go to their own designated areas. This part is called the (and I just know I'm going to butcher this, since Latin is not my first language and it's been years since we learned this at university) cauda equina, or horse tail. This is the area you'd want to tap for maximum carnage, since the gradient would hit a ton of nerves at different positions, and unceremoniously cause someone to crumple to the floor in horrible agony while simultaneously soiling their trousers in every way imaginable...
I've been trying to find videos of people using this on themselves but no one dares. I want to see if it is good enough for actual self defence, if not then maybe as a scare tactic atleast.
I am aware of all of this but I am not in the UK, I'm in Sweden and then it falls under the knifelaw. But the thing is at the moment there is a crimespree in my area and I have weapons, knives and etc but if you used one of them on a person no matter what it'd be assault. Same if you used the taser on them, but the thing is that no criminal is stupid enough to file a report on your for using a taser. With a knife or if you shoot them then it will be obvious you have done something towards them. If I use a taser however just to scare them away, it leaves no mark, they run away and I protect my home. If they even did decide to report that I have an ilegall taser in my home it would be the most retarded thing you could do because then they are revealing that they were the thieves that have stolen from over 50 homes in the last year. So if I buy this it is to be at home at all times and mostly for scare tactics, if I end up stunning them I will of course call the police but I will remove the taser from my household and there will be zero evidence and I will have caught a criminal, the judges are really nice here and will say I did what I had to do. And considering I stopped future thievering I won't get any fines which I would have gotten. But then again, I could might aswell just use my metal bat I keep next to my door, got a set of gloves and baseballs there so I could get away with that aswell.
Hi! I'm actually using these for some scientific experiments and we therefore had to do a couple of measurements on those. We hooked it up to a high voltage resistor, split the voltage 2 ways and hooked it up to an oscillator. We have measured the frequency of the circuit to be roughly around 10 kHz (as far as I remember...) with peak voltage around 13 kV. I'm still getting around to cutting it open with a dremel, but I also plan to use a CT to map the insides. Thanks very much for this video, it has actually provided a lot of insight for me ;)
I ordered two. One I'm going to try to de-pot with various acids and solvents ranging from Acetone, TriChlor and Nitric Acid. If I succeed. I'll post the pics.
I was thinking more along the like of one lead being attached to the metal of the car and another lead being attached to the ground. "Don't touch my car..." "Well, I *warned* you..."
Danielle Harris I thought similar with hasp on shed with a PIR or radar sensor to switch it on if anyone was around. You still need a spark gap as the will burn out also only rated for around 30 sec bursts. Think it would be illegal though.
I built 2 electric fly swatters with these in them... they vaporize any sort of flies and can protect me from thieves ¯\_(ツ)_/¯. They work still after a year perfect, that's pretty impressiv compared what i've red that they "break" really fast
Artwertable As the length of the arc goes up,, the voltage goes up. This is due to the colapsing magnetic field. And this is why we were told not to stop a lawn mower by pulling the spark plug wire. And that is why they put a shorting strap at the end of the spark plug. ( back in the day ) When the electrical path is broken, the voltage goes up to the point that the current finds a path inside the curcuitry. And often times that is inside the coil itself. Once a carbon track is made, the coil is broken, shot, kaput, fried, no good.ect... Hope this helps,,,, ;-)
so if I put the output wires close together and make the arc smaller like bigclive demonstrated in the vid , they will last longer? so a shorter arc will protect the circuit more? ( sorry I'm a noob to electronics I want to use these for a project and need the module to last more than 5 minutes).
So willy should of said: As the voltage goes up, the length of the arc goes up? all I want to know is if I shorten the length of the arc will this reduce the chance of damaging the module? as this will lessen resistance so the current doesn't find its way into the module to damage it? (if that makes sense)
@@fluffyhead6377 Yes, it will help protect it. Basically if the unit makes a continuous arc when it is running, it is a happy bunny. If however the output leads are too far apart, the voltage can rise too much (no load) and it will wreck the module. Played around with a couple of these modules and they do NOT survive even a few seconds at full input voltage and output leads too far apart.
@Yuck Foutube I think you are a bit out there - possibly just missed out a decimal point? If this was correct, then the 40-60KW from the back of an old colour CRT type TV should arc around 700mm In reality it will strike an arc about 2 - 4 cm (give or take). Sure, once the air is ionized, you can "pull it" much further. DC will also allow for a longer arc as it doesn't extinguish twice per cycle. Also, take into account that many 250v mains rated switches only have a contact separation of a couple of mm. 1KV rated switchgear typically has a contact gap of about 6mm - and that is to ensure there is ZERO chance of arc over.
I had one of them which pushed 1v up to 100000v... paired it with a 18650, a switch and a 5v usb lipo charging board and placed everything in an empty notebook power supply. 👍 works great but scary af
a bill banning fire is in the next session of parliament. i have noticed a trend towards this over the last few years. christingle a local custom involving candles and small children. have banned real candles in favour of the artificial ones on the grounds that the little sods may set fire to each others hair. i miss the screaming as they drip hot wax over there hands, or each other.
Funny you should say that but in some places it is due to pollution control and smokeless zones you cannot have garden fires and where i live you are not allowed a real fire only gas or electric heating - and if the kids build a bonfire the fire brigade either take it away or put it out - Grrrrrrrrrrrr

@@DerH0ns These modules also have capacitors, not one but 3 across the high voltage terminals. The voltage on on fly zappers can be anywhere from 400v to 2500v. The distance across the mesh will vary according to the voltage. If you current limit this module, you can get lower voltage levels easily. The change which you need to make is to put additional capacitor with across the high voltage terminals with much smaller bleed resistor to prevent the fast discharge. The capacitors inside this module have 1.5mega ohm resistor as a bleeder so it discharges it within half a second or less. Now all you need to do is order 3 mesh, top and bottom one should have large hole size to allow easy mosquito entry and the one in between on should be small enough to not allow any mosquito to pass through. I used mesh size 5 for top and bottom and mesh size 40 for the middle layer. Now, find out which one is the ground or negative on this module by putting the terminals in the water, whichever terminal has bubbles surrounding it is your negative terminal. Connect negative terminal to the middle mesh and outer two meshes to the postive one and there you go! Use a push button to charge the capacitors and discharge it on the target, the one I made lacks the bleed resistor for longer operation time after charge. I forgot, I used single 18650 cell with 1 ohm resistor (to current limit) the module and output voltage and my mesh are 4mm apart. Keep in mind without the resistor, if you keep your modules button pressed your module will burn due to overcurrent. I've made another top level comment on this video which explains why this happens.
Stun guns are illegal in Australia, at least the state I live in. These however are shipped from within that state on eBay for $5. Guess there's some loophole going on. Either way thanks, because I've bought a couple.
I've watched quite a few of your videos and I love them. I realized during this one that I haven't subscribed yet! I am ABSOLUTELY rectifying this oversight at once!
But this module doesn't have 2 transformer. It uses step up stage followed by a voltage multiplier stage then storing it a few capacitors and discharging across the terminals. What kills the module when the terminal are distanced apart is not over voltage but overcurrent. When it fails the discharge the feedback lags, oscillator lags and the transformer saturates. On staturation there is nothing to limit the current flow as the inductance zeros and this results in overcurrent which burns the transistor. You can solve this by limiting the current and now even if you keep the terminals half a mile apart, it won't kill the module :) You are right that the frequency at transformer is quite high which if touched directly will not give any sensation but serious burns. The frequency is lowered through LC circuit, where transformer (coupled inductor) is the inductor and capacitors are put next to it to lower the frequency to short pulses which we can feel. The frequency of these pulses depends on the inductance/capicantance and frequency/duty cycle. Most people here use 18650 cell, if you put a 1ohm resistor in series, your modules lifespan will improve a lot! These modules are designed for Akaline cell operated tasers which have much higher internal resistance compared to the Lithium Ion cell as a result overcurrent is limited to some extent improving the life of the module. I used a flame thrower to melt the Resin then I scopped it using an oscilloscope.
When I worked in a store developing film and enlarging photos we had to take out the film from one time use cameras and it had a flash which was a huge problem. So after opening the camera to take out the film the first thing you did was short out the capacitor for the flash with a screwdriver to avoid getting zapped, it always made a quite loud bang and made dents into the metal of the screwdriver when you shorted it.
"This video contains alcohol, Technical stupidities, Profanities and Electric Shock!" Definitely an automatic like, then! :-D. I use these as the HV spray stage for a Van de Graaf unit, and they work well for that purpose.
If you want to dissolve the resin put it in a swimming pool or any container of water with a lot of chlorine. The resin will over time become softer and brittle and all you have to do next is scrape it off with a screwdriver or something. This happened to my fountain pump that is used in a chlorinated pond
yes, cds draw too much current and the main driver tranny pops, the cd is effectively a short although for some reason, they cause more damage than actually shorting the leads...maybe because directly shorting the leads isnt fun and we only do it for a fraction of a second, not 10s of a seconds
It would have been great to see you accurately measure the voltage output on these units similar to the way you do with LEDs or appliances. Fantastic video and relevant.
Oh god yes, I have like 4 of these (exact same model), yes they are stun guns, they have the two stages of the stun gun, super high voltage and a lower but more powerful pulse embedded in the high voltage, jolly good fun they are.
Haha....I didn't have to touch it to know it's was bad...just spent $2.38, patiently waited and when arrived hooked it to a 9V and just smiled after I shit my pants a little HAHAHA
I would not recommend using electronic power supplies to run these, they take awul pulse loads and shoot back terrible voltages and noise all over the shop. Batteries don't care as much.
MyBigThing2010 the other thing with using a mains power supply is even though it may output 5v it is likely to be referenced to mains. Remember not long back a girl dropped her mobile in the bath which was only connected by a USB lead.
I remember seeing an amateur electronics handbook which detailed how to make one of these from wine corks and nails. with a breakaway prong and wire extension. And a bunch of other plans for making dangerous or sketchy devices. This book was found in a high school library in the mid 90s.
I removed the spark unit from an old gas cooker a few yrs ago , it has a similar output but the frequency of the spark is lower. I used it to set off a hairspray fueled spud gun but it left a small hole in my living room ceiling.. oh how I laughed , 'till the missus saw it...
They use those modules in those LED flashlight / Stun guns mainly. The flashlights run off a 16850 Li-Ion cell and typically have a charger circuit built into them also
I like the idea, but you'd need some way to trigger it only when a squirrel is present. Otherwise, the generator will probably burn out. Even if it doesn't, the constant arcing would be annoying. How about a long tube that fits over the bird feeder pole; two bare wires spiral in parallel down the tube; the squirrel's weight on the tube triggers a power switch...
Better off with an electric fence controller. I have a bird feeder on a wooden post with two leads spiraled around it from the controller. You need a + lead and ground lead for the squirrel to ground out. Birds never land on the post so they are safe. You can tell how much the squirrels love it by the way they ricochet about the yard while running away.
I used to work for an electronics manufacturer. That potting material is very hard to remove but it is possible. Use a heat gun to soften the material and then you can slowly pick it out. You may end up ripping some of the small SMT components, or in this case fine wiring, but it is still possible.
My friends and I brought one of these to school, and used a sharpie to notate different muscle groups on our arms, and shocked them and we were able to move our arms with it. The vice principal walked over and asked what was going on, and surprisingly walked away after and let us continue or dangerous science. This was like a year ago, before the pandemic
In the early 1980's I was working in Nigeria for civil aviation. Staying in the same hotel were UK Special Forces who were training the Nigerian Special Forces on the HALO technique, where the parachutist opens their parachute at a low altitude after free-falling for a period of time. They had the early versions of the stun gun. The plastic weapon had at the business end of this handheld device two square holes where you placed the explosive barb capsules - they look like the old camera flash cubes that were available at that time. Anyway to use you simply aimed at an object the trigger had two positions first position brought on a bright flashlight and the second shot out two very thin wires that were connected to the weapon that had barbs on the end of the wire. These would be attached/caught in what you aiming at.... clothing or skin etc then sent out a high voltage to disable a person. So there I was holding this device and told to aim it at the pillow on one of the beds - on came the flashlight and then bang the two wire connected barbs shot out and stuck in the pillow - I was told to keep the trigger pressed and you could hear and see a bright electric discharge and the pillow starting to burn... I didn't fire the second capsule I didn't know much about the SAS then and as a young 22 year old was very impressed with the device. So it's taken quite some time before what we now know as a stun gun to be with our civilian emergency services.
I use one of these along with a constant current regulator board in a DIY powder coating electrostatic gun that i hook up to my air compressor to blow the powder. Its basically some PVC pipe with a T fitting and one side of the top of the T plugged. The bottom of the T is attached to a threaded cap for a glass bottle which holds the poweder. The plugged side of the T has an air coupling on it, along with a piece of tubing that runs through the plug and down into the bottle. The electricity bit connects to a piece of copper solid wire that runs down the main piece of PVC tubing and every inch is a piece soldered to it which keeps everything centered. So air is blown into the bottle which blows the powder up and through the threaded bit, then down the tube with the copper thats electrified. This charges the powder and it sticks to any grounded metal just like a $400 gun. Works great, not one shock. And so far i've gone through 5 pounds of powder using the gun on various projects. screw paint. powdercoat rules.
I bought a pair last year when JulianIlett tried one and jumped out of his skin. Everytime i run mine (even in the garden) it tends to kill bits of my home automation system. I've seen them used as emp killers.
I did an interesting experiment with one of those. I put the contacts about 1cm apart and in a closed glass container with a hose to pump air in and another to let get out again. I put some pure water in the bottom of the container along with a magnetic stirring pill. I turned the magnetic stirring machine up to almost max. so that the water kept splashing around a lot, mixing with the air inside without touching the contacts. I then turned it on for a few seconds, blew new air into it, and repeated the process several times. I then turned everything off and measured the PH level of the water, which was around 1 because the electric arc turned some of the nitrogen in the air into Nitric Acid. This experiment is based on an experiment from the 30s I believe. If you would make it solar powered in your backyard, you could slowly produce nitric acid in your backyard for free essentially. :)
Just curious if they were still out there in 2019, sure as hell, pages of dealers selling these things for around 3 bucks US! Wish I could figure out something to use them for, but I can't so I guess I shan't order one. Back in 1973 I was working on a PD in the Dakota's, the local Sheriff had heard that I was a sort of electronic whiz (even back then, yes I am an old time radio shack guy!) so he brought me this little device he used to train horses (he was a rancher in real life, and Sheriff on the side!) It was housed in a sort of clear plastic shell, took one AA battery and had a sort of buzzer in it, as well as what appeared to be a small transformer and some other components. The two prods were the sort that when pressure was applied they collapsed and made contact inside the device, triggering the current. He used it to train his horses, giving them a jolt when they didn't do as he ordered through his knees signals or through the rains. Well I looked it over, and that vibrator thing looked a lot like points on a car, so taking the point file out of my mechanic kit that I carried in the trunk of my car, I filed them a bit and cleared the pitting and burn marks, the device began to function once more. When I was at coffee the next day at a local cafe, one of the waitresses asked what it was, and I explained, she wanted to test it, brave girl there! It looked so small and just that little AA battery could not hurt much she thought, well she was wrong and quickly learned that horses were much tougher then we puny humans. Now it didn't put her down, but the scream she emitted when it hit her was enough for the entire cafe to look our way, dishes were dropped and silverware hit the floor. I returned it to the Sheriff, who gave me a ten spot for my trouble, he was happy and that waitresses refused to serve me for a couple of weeks, oh well there were other cafe's in the town.
What is the current draw at various input voltages, such as when connected to two AA batteries I wonder? I've ordered one and it says 3-6V, so am keen to see what size gap the spark can jump when powered from a 6vdc input from a power supply and how much it draws. :-)
Another amazingly video from Clive. I maybe I should make those pained screams my new mobile phone ringtone? Thanks for taking the hit so that we don't have to, Clive!
I bought some of these recently and the furthest distance between the output wires I'd say is about an inch and a half. More than that won't establish an arc. Also something worth noting with these modules and stun guns/tasers is once a load (i.e. a person) is placed across the output, the voltage drops significantly. A stun gun might be able to produce 40-50kV on an open-circuit, but as soon as there's load it's output is limited to maybe a couple thousand volts. I have yet to test one of the modules on myself, just running them off my bench supply the arc is extremely bright and LOUD!!! Very intimidating!😳Even my tesla coil which is capable of producing >200kV feels safer lol (and yes I've touched it, however as it's high frequency it really only burns)
When I was in the States I picked up an electric fly swatter. I thought it was a child's tennis racket, by the wrong end. And it went off. I got a good jolt from the sucker. New respect for these devices. Great videos and many thanks. Greetings from Africa.
Well ya got part of the circuit for these particular modules right. Good explanation on stun guns though. I've actually bought a few of these things a little back, burnt one out, and actually went threw the hastel of slowly carving then entire epoxy fill away with an exacto knife. Couple days and many marks on my fingers from the knife later, i had a circuit diagram of the module.(maybe ill go find it again if anyone wants). On the HV side it uses a variant of a Cockcroft-Walton voltage multiplier, 3x i think, but there was something weird about it. that charges 3 series capacitors that give you your spark. there is a discharge resistor in place as well. anyways i did manage to get some values from testing the components off the dead one, diodes were fine, but the main HV caps seam to be the failure point. they seam WAY under rated for this application. Oh, and these things make for a great ignition source on potato cannons. If anyone wants ill go and find my circuit diagram findings on this thing.
That's what I suspected. I've seen plans before for voltage-multiplier DC circuits to use as "stun guns". I'm pretty sure they don't work, except to annoy someone who already wants to hurt you. If you carry a weapon, you have to be sure your assailant can't take it off you, cos then you're really Donald Ducked.
I used one of the smaller brothers of these to charge a capacitor the size of my upper leg. It was quite spectacular to discharge it according to safety regulations.
That resin potting also probably suggests stun-gun module otherwise there would likely be arcs across various components and the module would likely destroy itself.
The power supply in my Quad electro static speakers uses a small TX that gives about 600V then a rectifier then a diode capacitor ladder arrangement. The bass panels have about 6KV and the trebble panels about 1.5 KV on the grid.
its the weak and crooked politicians working for satan that done this ,you see its easier for the darkside to carry out their plans when there is little resistance , look whats happening in america ,same thing looks to be in motion !
It's not illegal to defend yourself. And at least if these are illegal, it keeps them out of the hands of the people who want to stab and rob you. You can get hold of these on the black market but they're very rare. I vaguely know, or have known, the sort of people who might be able to get this sort of thing. But nobody's ever actually shown me one. So the ban is pretty effective. The thing about carrying a weapon is, you have to be sure your assailant can't take it off you. Cos then you're double-fucked, you've just armed the bloke, and he's incredibly pissed off because you tried to electrocute him. It's not like Arnie films where you make a sarky remark and he fucks off crying. The best defence is a good pair of running shoes.
I have one of these that is 800kv that I purchased from Banggood. They are not really for stun guns, they are used for igniting gas. Like the ignition for a gas stove or LPG heater. They can be used for pest control as well, like in a bug zapper.
I don't remember where I got mine (the one in this video) but keep in mind 800kv would be able to make sparks approximately 80cm in length. I can assure you these can't.
That is the rating that the product get's, but lets face it. More than likely it is 80kv. That makes more sense as a cars ignition coil is about 45 to 80kv depending on the ignition system.
It'd be nice to be able to connect one of these to an overhead power line, and pump in a higher voltage than they normally carry. For a brief moment, you'd be powering the National Grid.
Hey! A European that agrees that weapon laws aren't blessings from altruistic government, and that maybe once in a while they have ulterior motives for doing that. We might not agree on what constitutes excessive, but we can agree that what you guys have is excessive.
The latest trend across "fly over country" where I live, is an end to the requirement to pass some sort of test, or background check before you can carry your firearm concealed, locked and loaded! North Dakota passed the law a couple of years ago, in South Dakota (where I have my concealed carry permit) the bill is setting on our very conservative Governor's desk awaiting her signature, is should come tomorrow. It is called by those who are trying to get this passed nation wide, the "Constitutional Carry Law. They are in hopes to get the law changed till it is the law of the land, and any man, or woman over the age of 21 can legally carry a loaded firearm on their person, in their cars, and of course in their homes. It should prove to be a good thing, in States that have had this law for many years, a sever drop in crime has been noted, especially in burglary, home invasion and car-jacking incidents. What criminal in their right mind would try to car-jack from someone who has the legal right, and ability to carry a loaded gun. Many of the States also have the "Stand your Ground" laws, so have no legal responsibility to run away from a fight when crime comes their way. I am sure these laws stand no chance in the coast areas of our nation, where liberal gather and wring their hands at the approach of freedom and personal responsibility, and that is where these slaughters that happen in the schools and such usually happen. Sure there was the one in Vegas, but that is an entirely different world from the rest of the US, and with all the people we have here, such shit is bound to happen from time to time, but overall we are a pretty much law abiding bunch, here in fly over country, where the sheriff can be 100 miles away, the cops 40 miles away, and the criminal at your window. We take care of our own, and our neighbors, sometimes it takes a handgun, sometimes it take an AR-15 but in the end, we do what must be done, when the shit hits the fan.
For many people asking = if this is powered but idle (ie the output circuit is open) then it burns quite quickly. Therefore you can not, say, connect it to a fence for squirrels and just leave. Perhaps some similar model would have this ability, but not this one.
Well if we don't see you again we know the UK police happened upon your channel and got evidence of you harboring a stun gun and using it. Good channel 285K subscribers will miss you.
Tech note if you have a Hot Air station you can sometimes soften 2pt epoxy and some other potting materials letting you peel it out like snot, Set temp about 115-145f and heat just enough that it becomes pliable This also has worked for me with the Tar used to seal some consumer fireworks.

I bought several of them and tried connecting 1 up to 2 charged 1860s in series and it was quite spectacular trying to get the longest spark I could out of it, but my fun was short lived and it died, never mind at least I have spares. They also work real well as cat repellents!
i thought that at first, but there would be no point. fast recovery is more important in this case .there is no shortage of voltage which is where schottkys would be better.
The UK can say they do not want you protecting themselves against criminals, but its a matter of they don't want you having weapons to protect yourselves from them. They learned a lesson that started in Boston USA years ago.
Being safer than an American doesn't suck. Having to never even consider the possibility that one of my kids will get their head blown off by a bullied classmate is quite refreshing.

S.A. Smith however if they become more common, I then have to worry about Joe Bloggs carrying one on the street when he gets pissed at my driving for no reason.

Dick's will be Dick's, let's not give them legal remit to be bigger Dick's.
Actually not, this is a power supply. I bought 4 of them and did make a stun gun. Put this output on a meter and scope and you will see that there is diode inside that charges a 2800pF capacitor which is across the output leads. When the voltage gets to the recommended arc distance, then the spark jumps. You can load this with some resistors in the megohm region and see that the output is DC. The recommend spark distance not exceeding 3/4" will show a charge of 13KV.

I have the same HV Modlue and I built a small tazer.
An important thing to remember about these HV Modules, is to not separate the output wires too far apart or the stored energy cannot jump the wires and end up discharging inside and destroy the module.
About 1 " is good.
Hi i want a tazer from one of these but i want 0 risk of it being lethal and know im probaly not going to use it on a person unless i really need to but i dont want it to me lethal and i know this comment was 6 years ago but do i need to put a resistor to lower amps or anything or does the voltage mutiplier do it
@@PIXELCRAFT_HD
It will give you a good shock, but it won't damage you unless you have cardiac issues. No resistor needed. This is very low current and high voltage. Much like a dog shock collar. Have fun...
@@valveman12 thank you
also what battery did u use into the voltage multiplier
@@PIXELCRAFT_HD
I used 2 AA batteries with my design. 2 AA Batteries create a nice arc.
If it's any consolation, I once spent a couple weeks of spare time extremely carefully chipping the potting material off one of these modules. The one I've got uses a voltage tripler at the output of the transformer, but does not have any separate stepup pulse transformer. The sparking you're getting is just the discharging of the final cap of the multiplier. I'll send you some photos 😁
+Lindsay Wilson That would be interesting. It does look like it may be a different style based on an HV transformer and multiplier.
Actually there are quite a few different versions around. Not all of them have the pulse transformer, like yours obviously has.
Lindsay Wilson can you send me them
I have seen x-ray of one of these on internet, and it does seem to have a voltage multiplier on the output
Oliwer Gumowski Neat! Do you have a link for that?
Same where I live. You can buy a 200lbs crossbow with arrows and hunting tips, but you dare not get caught with a slingshot, cause that is considered an illegal weapon.
jaaasgoed The UK government banned privately owned and police monitored pistols that were kept for sporting use (target shooting on registered ranges). The idea was to keep guns away from criminals. Now the criminals have lots of guns. Maybe someone in the government found a ready market. Maybe I am getting old and cynical.
jaaasgoed reminds me of getting full black Airsoft replicas, you have to jump through so many hoops and yet you can buy an air rifle if you're 18.
That's one heavy crossbow.
200lbs is not the weight, but the draw-weight. In effect you are putting 200lbs of energy behind the projectile. The traditional English longbow for example had a 100-120lbs draw-weight. You'd have to train to be able to draw the bow back to it's full strength and therefore the most energy goes pushing the projectile. This tends to be true for compound bows rather than the recurve style you see on the Olympics for example. Compounds tend to require enormous physical skill, strength and technique in order to achieve raw power. Recurves tend to ditch that in favour of precision and accuracy.
The idea of draw weight though did transfer over to the crossbow, though it's slightly misleading with modern crossbows. Original crossbows required less physical technique as you could hold it down with your foot and pull back the string using both hands. Equally, modern crossbows have all sorts of ratchets and such that aid in drawing back the string. Ultimately, the crossbow became popular because whilst the longbow required massive levels of training and skill to use well, the crossbow could be used by anyone with minimal training and still achieve a fair result.
No, Denis, the idea was to keep guns away from lunatics! Michael Ryan, Thomas Hamilton and Derrick Bird were all law-abiding citizens up until the day they went on double-figure killing sprees, just as how every perpetrator of a mass shooting in the US is a law abiding citizen up until the moment they snap and kill everyone in their school/college/office building.
"completely unavoidable profanities" making this module basically, a FUCKING HELL machine 😂
I have build one of those inside my insect zapper, which is formed like a tennis racket. I also included a spdt switch to select whether it is running on only one single AA battery or if both included cells of the zapper are used. Running at 1.5V the zapper is quiet and only zapps when an insect is near the zapping plate. When run in 3V mode, continuous zapping with loud sparks happens all over the plate, mostly on a few single spots.
This build is so much fun to zap things with, as even a short swosh through the air definately takes out every creature near by. You can even clean your bed with it zapping, as a static charge will catch small debree on the metal gates on the tennis racket like plate of this device. Small tapping on the handle will release all partikles.
The power consumption is around 1A on both modes, so somewhere between 1.5W and 3W.
Even operated with NiMh cells it is working reliable. To get the indicator LED of the zapper running on the single cell mode, i used a energy thief circuit. This allowed me to even change the LED to a high power 5mm ultra bright diode, which adds to the whole experience using the device.
I don't regret investing the time this conversion took and would alleays do it again.
From the beginning i planned for the inclusion for an ESP8266, which allows for integration in my smarthome. Count zapped things over the year and generate statistics. Through the inclusion of a small mosfet even the following is now reality:
Hey Google, kill this fly for me.
...there you go, i activated your insect zapper. Please hold it near the bug which is soon to be gone...

When we get certified for use of stunguns we have to enjoy the experience of receiving a rather lengthy demonstration of the power, usually resulting in a ear splitting scream usually reserved for scared 6 year old girls or in my case a 300 pound hog screaming like a jet on take off. We have to do this for every modle we may use. I always choose to be the first, because if I watched after the first one I'd be gone and since I'm the Officer In Charge, I have to go through the certification. My best friend shot me with a stungun that fire probes. I was nervous, stunguns had just came out and we got some of the fist made for the Corps. So I'm facing my mate and I hear TAZER TAZER TAZER!

There is actually more to that, the reason you would be aiming for the base of someone's spine is that for quite a significant portion of the spinal column the nerves will all be bunched together into this thick cable like arrangement with individual isolating layers, but near the base of the spine, the nerve bundles that handle operations of your legs and everything close to them split back into separated wires that then go to their own designated areas. This part is called the (and I just know I'm going to butcher this, since Latin is not my first language and it's been years since we learned this at university) cauda equina, or horse tail. This is the area you'd want to tap for maximum carnage, since the gradient would hit a ton of nerves at different positions, and unceremoniously cause someone to crumple to the floor in horrible agony while simultaneously soiling their trousers in every way imaginable...

Keystone Science I made your taser you made with it that’s how I got here
Keystone Science stun gun*
I am aware of all of this but I am not in the UK, I'm in Sweden and then it falls under the knifelaw. But the thing is at the moment there is a crimespree in my area and I have weapons, knives and etc but if you used one of them on a person no matter what it'd be assault. Same if you used the taser on them, but the thing is that no criminal is stupid enough to file a report on your for using a taser. With a knife or if you shoot them then it will be obvious you have done something towards them. If I use a taser however just to scare them away, it leaves no mark, they run away and I protect my home. If they even did decide to report that I have an ilegall taser in my home it would be the most retarded thing you could do because then they are revealing that they were the thieves that have stolen from over 50 homes in the last year.
So if I buy this it is to be at home at all times and mostly for scare tactics, if I end up stunning them I will of course call the police but I will remove the taser from my household and there will be zero evidence and I will have caught a criminal, the judges are really nice here and will say I did what I had to do. And considering I stopped future thievering I won't get any fines which I would have gotten. But then again, I could might aswell just use my metal bat I keep next to my door, got a set of gloves and baseballs there so I could get away with that aswell.

Hi! I'm actually using these for some scientific experiments and we therefore had to do a couple of measurements on those. We hooked it up to a high voltage resistor, split the voltage 2 ways and hooked it up to an oscillator. We have measured the frequency of the circuit to be roughly around 10 kHz (as far as I remember...) with peak voltage around 13 kV. I'm still getting around to cutting it open with a dremel, but I also plan to use a CT to map the insides. Thanks very much for this video, it has actually provided a lot of insight for me ;)

As the length of the arc goes up,, the voltage goes up. This is due to the colapsing magnetic field. And this is why we were told not to stop a lawn mower by pulling the spark plug wire. And that is why they put a shorting strap at the end of the spark plug.
( back in the day )
When the electrical path is broken, the voltage goes up to the point that the current finds a path inside the curcuitry. And often times that is inside the coil itself. Once a carbon track is made, the coil is broken, shot, kaput, fried, no good.ect...
Hope this helps,,,, ;-)
so if I put the output wires close together and make the arc smaller like bigclive demonstrated in the vid , they will last longer? so a shorter arc will protect the circuit more? ( sorry I'm a noob to electronics I want to use these for a project and need the module to last more than 5 minutes).
So willy should of said: As the voltage goes up, the length of the arc goes up? all I want to know is if I shorten the length of the arc will this reduce the chance of damaging the module? as this will lessen resistance so the current doesn't find its way into the module to damage it? (if that makes sense)
@@fluffyhead6377 Yes, it will help protect it. Basically if the unit makes a continuous arc when it is running, it is a happy bunny. If however the output leads are too far apart, the voltage can rise too much (no load) and it will wreck the module. Played around with a couple of these modules and they do NOT survive even a few seconds at full input voltage and output leads too far apart.
@Yuck Foutube I think you are a bit out there - possibly just missed out a decimal point?
If this was correct, then the 40-60KW from the back of an old colour CRT type TV should arc around 700mm In reality it will strike an arc about 2 - 4 cm (give or take). Sure, once the air is ionized, you can "pull it" much further. DC will also allow for a longer arc as it doesn't extinguish twice per cycle.
Also, take into account that many 250v mains rated switches only have a contact separation of a couple of mm.
1KV rated switchgear typically has a contact gap of about 6mm - and that is to ensure there is ZERO chance of arc over.
I had one of them which pushed 1v up to 100000v... paired it with a 18650, a switch and a 5v usb lipo charging board and placed everything in an empty notebook power supply. 👍 works great but scary af
Is fire still legal in the UK, or has that been banned too?
My Ingroup Idol Did Nothing Wrong No, and neither is the sun. Which is why we all go to Spain during the summer.

@@andygozzo72 Those are only 400V but rather high current due to an capacitor across the transformer output
@@DerH0ns These modules also have capacitors, not one but 3 across the high voltage terminals.
The voltage on on fly zappers can be anywhere from 400v to 2500v. The distance across the mesh will vary according to the voltage.
If you current limit this module, you can get lower voltage levels easily.
The change which you need to make is to put additional capacitor with across the high voltage terminals with much smaller bleed resistor to prevent the fast discharge.
The capacitors inside this module have 1.5mega ohm resistor as a bleeder so it discharges it within half a second or less.
Now all you need to do is order 3 mesh, top and bottom one should have large hole size to allow easy mosquito entry and the one in between on should be small enough to not allow any mosquito to pass through. I used mesh size 5 for top and bottom and mesh size 40 for the middle layer.
Now, find out which one is the ground or negative on this module by putting the terminals in the water, whichever terminal has bubbles surrounding it is your negative terminal.
Connect negative terminal to the middle mesh and outer two meshes to the postive one and there you go!
Use a push button to charge the capacitors and discharge it on the target, the one I made lacks the bleed resistor for longer operation time after charge.
I forgot, I used single 18650 cell with 1 ohm resistor (to current limit) the module and output voltage and my mesh are 4mm apart.
Keep in mind without the resistor, if you keep your modules button pressed your module will burn due to overcurrent. I've made another top level comment on this video which explains why this happens.

'I stuck it in my thigh and pulled the trigger... it had to be done!' that's Clive for ya'. LOL
But this module doesn't have 2 transformer. It uses step up stage followed by a voltage multiplier stage then storing it a few capacitors and discharging across the terminals.
What kills the module when the terminal are distanced apart is not over voltage but overcurrent.
When it fails the discharge the feedback lags, oscillator lags and the transformer saturates. On staturation there is nothing to limit the current flow as the inductance zeros and this results in overcurrent which burns the transistor.
You can solve this by limiting the current and now even if you keep the terminals half a mile apart, it won't kill the module :)
You are right that the frequency at transformer is quite high which if touched directly will not give any sensation but serious burns.
The frequency is lowered through LC circuit, where transformer (coupled inductor) is the inductor and capacitors are put next to it to lower the frequency to short pulses which we can feel.
The frequency of these pulses depends on the inductance/capicantance and frequency/duty cycle.
Most people here use 18650 cell, if you put a 1ohm resistor in series, your modules lifespan will improve a lot!
These modules are designed for Akaline cell operated tasers which have much higher internal resistance compared to the Lithium Ion cell as a result overcurrent is limited to some extent improving the life of the module.
I used a flame thrower to melt the Resin then I scopped it using an oscilloscope.
This is one of my favorite videos! Alcohol, electric shocks and profanity! What more could one ask for?
When I worked in a store developing film and enlarging photos we had to take out the film from one time use cameras and it had a flash which was a huge problem. So after opening the camera to take out the film the first thing you did was short out the capacitor for the flash with a screwdriver to avoid getting zapped, it always made a quite loud bang and made dents into the metal of the screwdriver when you shorted it.
Those were not dents.. that was metal vaporizing.
"This video contains alcohol, Technical stupidities, Profanities and Electric Shock!" Definitely an automatic like, then! :-D. I use these as the HV spray stage for a Van de Graaf unit, and they work well for that purpose.
If you want to dissolve the resin put it in a swimming pool or any container of water with a lot of chlorine.
The resin will over time become softer and brittle and all you have to do next is scrape it off with a screwdriver or something.
This happened to my fountain pump that is used in a chlorinated pond
Mine lasted for about 30 seconds, probably because I got a little carried away while vaporising the metal layer on CDs ;)
yes, cds draw too much current and the main driver tranny pops, the cd is effectively a short although for some reason, they cause more damage than actually shorting the leads...maybe because directly shorting the leads isnt fun and we only do it for a fraction of a second, not 10s of a seconds
never heard such a nice sounding man swear like that
It would have been great to see you accurately measure the voltage output on these units similar to the way you do with LEDs or appliances. Fantastic video and relevant.
It is difficult, and it's hard to choose a way of measuring it that is satisfactory.
Oh god yes, I have like 4 of these (exact same model), yes they are stun guns, they have the two stages of the stun gun, super high voltage and a lower but more powerful pulse embedded in the high voltage, jolly good fun they are.
Haha....I didn't have to touch it to know it's was bad...just spent $2.38, patiently waited and when arrived hooked it to a 9V and just smiled after I shit my pants a little HAHAHA
Best not a 9v if you don't know if it can handle it, start with 3 and work your way up.
Use the 5V output from an ATX power supply. Easily capable of more than enough current to drive this.
try a power bank. But keep in mind theses zappers draw currents far in excess of 1.5A.
I would not recommend using electronic power supplies to run these, they take awul pulse loads and shoot back terrible voltages and noise all over the shop. Batteries don't care as much.
MyBigThing2010 the other thing with using a mains power supply is even though it may output 5v it is likely to be referenced to mains. Remember not long back a girl dropped her mobile in the bath which was only connected by a USB lead.
I remember seeing an amateur electronics handbook which detailed how to make one of these from wine corks and nails. with a breakaway prong and wire extension. And a bunch of other plans for making dangerous or sketchy devices. This book was found in a high school library in the mid 90s.
I removed the spark unit from an old gas cooker a few yrs ago , it has a similar output but the frequency of the spark is lower. I used it to set off a hairspray fueled spud gun but it left a small hole in my living room ceiling.. oh how I laughed , 'till the missus saw it...
They use those modules in those LED flashlight / Stun guns mainly. The flashlights run off a 16850 Li-Ion cell and typically have a charger circuit built into them also
Could you work this into a squirrel proof bird feeder. Stimulate their nerves.
I like the idea, but you'd need some way to trigger it only when a squirrel is present. Otherwise, the generator will probably burn out. Even if it doesn't, the constant arcing would be annoying.
How about a long tube that fits over the bird feeder pole; two bare wires spiral in parallel down the tube; the squirrel's weight on the tube triggers a power switch...
Better off with an electric fence controller. I have a bird feeder on a wooden post with two leads spiraled around it from the controller. You need a + lead and ground lead for the squirrel to ground out. Birds never land on the post so they are safe. You can tell how much the squirrels love it by the way they ricochet about the yard while running away.
MrCivildefense have a weight activated switch. Should work.
haha they're tiny! it'll probably kill them not stimulate their nerves!
I used to work for an electronics manufacturer. That potting material is very hard to remove but it is possible. Use a heat gun to soften the material and then you can slowly pick it out. You may end up ripping some of the small SMT components, or in this case fine wiring, but it is still possible.
My friends and I brought one of these to school, and used a sharpie to notate different muscle groups on our arms, and shocked them and we were able to move our arms with it. The vice principal walked over and asked what was going on, and surprisingly walked away after and let us continue or dangerous science. This was like a year ago, before the pandemic
In the early 1980's I was working in Nigeria for civil aviation. Staying in the same hotel were UK Special Forces who were training the Nigerian Special Forces on the HALO technique, where the parachutist opens their parachute at a low altitude after free-falling for a period of time.
They had the early versions of the stun gun. The plastic weapon had at the business end of this handheld device two square holes where you placed the explosive barb capsules - they look like the old camera flash cubes that were available at that time.
Anyway to use you simply aimed at an object the trigger had two positions first position brought on a bright flashlight and the second shot out two very thin wires that were connected to the weapon that had barbs on the end of the wire. These would be attached/caught in what you aiming at.... clothing or skin etc then sent out a high voltage to disable a person.
So there I was holding this device and told to aim it at the pillow on one of the beds - on came the flashlight and then bang the two wire connected barbs shot out and stuck in the pillow - I was told to keep the trigger pressed and you could hear and see a bright electric discharge and the pillow starting to burn... I didn't fire the second capsule
I didn't know much about the SAS then and as a young 22 year old was very impressed with the device.
So it's taken quite some time before what we now know as a stun gun to be with our civilian emergency services.
Another weapon for derpy police to accidentally kill a load of people with, what a bright idea.

I use one of these along with a constant current regulator board in a DIY powder coating electrostatic gun that i hook up to my air compressor to blow the powder. Its basically some PVC pipe with a T fitting and one side of the top of the T plugged. The bottom of the T is attached to a threaded cap for a glass bottle which holds the poweder. The plugged side of the T has an air coupling on it, along with a piece of tubing that runs through the plug and down into the bottle. The electricity bit connects to a piece of copper solid wire that runs down the main piece of PVC tubing and every inch is a piece soldered to it which keeps everything centered. So air is blown into the bottle which blows the powder up and through the threaded bit, then down the tube with the copper thats electrified. This charges the powder and it sticks to any grounded metal just like a $400 gun. Works great, not one shock. And so far i've gone through 5 pounds of powder using the gun on various projects. screw paint. powdercoat rules.
I bought a pair last year when JulianIlett tried one and jumped out of his skin. Everytime i run mine (even in the garden) it tends to kill bits of my home automation system. I've seen them used as emp killers.

I turned the magnetic stirring machine up to almost max. so that the water kept splashing around a lot, mixing with the air inside without touching the contacts. I then turned it on for a few seconds, blew new air into it, and repeated the process several times. I then turned everything off and measured the PH level of the water, which was around 1 because the electric arc turned some of the nitrogen in the air into Nitric Acid. This experiment is based on an experiment from the 30s I believe. If you would make it solar powered in your backyard, you could slowly produce nitric acid in your backyard for free essentially. :)
OOOH! - could be useful for getting through the crowds in Tesco on a Friday evening!
Just curious if they were still out there in 2019, sure as hell, pages of dealers selling these things for around 3 bucks US! Wish I could figure out something to use them for, but I can't so I guess I shan't order one. Back in 1973 I was working on a PD in the Dakota's, the local Sheriff had heard that I was a sort of electronic whiz (even back then, yes I am an old time radio shack guy!) so he brought me this little device he used to train horses (he was a rancher in real life, and Sheriff on the side!) It was housed in a sort of clear plastic shell, took one AA battery and had a sort of buzzer in it, as well as what appeared to be a small transformer and some other components. The two prods were the sort that when pressure was applied they collapsed and made contact inside the device, triggering the current. He used it to train his horses, giving them a jolt when they didn't do as he ordered through his knees signals or through the rains. Well I looked it over, and that vibrator thing looked a lot like points on a car, so taking the point file out of my mechanic kit that I carried in the trunk of my car, I filed them a bit and cleared the pitting and burn marks, the device began to function once more. When I was at coffee the next day at a local cafe, one of the waitresses asked what it was, and I explained, she wanted to test it, brave girl there! It looked so small and just that little AA battery could not hurt much she thought, well she was wrong and quickly learned that horses were much tougher then we puny humans. Now it didn't put her down, but the scream she emitted when it hit her was enough for the entire cafe to look our way, dishes were dropped and silverware hit the floor. I returned it to the Sheriff, who gave me a ten spot for my trouble, he was happy and that waitresses refused to serve me for a couple of weeks, oh well there were other cafe's in the town.
Could be interesting, if used in conjunction with that strange pointy mushroom shaped "tens" module that you had the other week.
Yep I have a few of those. I've taken apart a cheap flashlight stungun and it had one inside.
We've all zapped ourselves working with electronics,ive done a few doosies in the shop myself but,wow man that looked painful
my biggest shock ive had from my projects was a real 400kv, over 200mm spark gap.
Now thats a proper shock. you are lucky to still be alive.
I read that they increased the amperage, certainly in the military/law enforcement devices, which makes them extremely effective.
connect a xenon strobe tube across the output!
would be interesting to see if you can get it to strike and how much light output there would be.
I bought one to replace the trembler coil on a Model T Ford buzz coil box. It's also great for firing up my pulse Jet motor.
What is the current draw at various input voltages, such as when connected to two AA batteries I wonder?
I've ordered one and it says 3-6V, so am keen to see what size gap the spark can jump when powered from a 6vdc input from a power supply and how much it draws. :-)
I have saved a few of these from old split system aircon units! So cool and fun!
Another amazingly video from Clive. I maybe I should make those pained screams my new mobile phone ringtone?
Thanks for taking the hit so that we don't have to, Clive!
I bought some of these recently and the furthest distance between the output wires I'd say is about an inch and a half. More than that won't establish an arc. Also something worth noting with these modules and stun guns/tasers is once a load (i.e. a person) is placed across the output, the voltage drops significantly. A stun gun might be able to produce 40-50kV on an open-circuit, but as soon as there's load it's output is limited to maybe a couple thousand volts.
I have yet to test one of the modules on myself, just running them off my bench supply the arc is extremely bright and LOUD!!! Very intimidating!😳Even my tesla coil which is capable of producing >200kV feels safer lol (and yes I've touched it, however as it's high frequency it really only burns)
Stun gun manufacturer orders 100k of these modules, the factory makes 200k and sells the rest on Ebay? :D
When I was in the States I picked up an electric fly swatter. I thought it was a child's tennis racket, by the wrong end. And it went off. I got a good jolt from the sucker. New respect for these devices. Great videos and many thanks. Greetings from Africa.
Well ya got part of the circuit for these particular modules right. Good explanation on stun guns though. I've actually bought a few of these things a little back, burnt one out, and actually went threw the hastel of slowly carving then entire epoxy fill away with an exacto knife. Couple days and many marks on my fingers from the knife later, i had a circuit diagram of the module.(maybe ill go find it again if anyone wants). On the HV side it uses a variant of a Cockcroft-Walton voltage multiplier, 3x i think, but there was something weird about it. that charges 3 series capacitors that give you your spark. there is a discharge resistor in place as well. anyways i did manage to get some values from testing the components off the dead one, diodes were fine, but the main HV caps seam to be the failure point. they seam WAY under rated for this application. Oh, and these things make for a great ignition source on potato cannons. If anyone wants ill go and find my circuit diagram findings on this thing.
hey, would you mind sharing the circuit diagram?
@@smithaamohanraj6516 was a while ago, dnt got it anymore
The module is a dc voltage multiplier using the cockcroft circuit. Using a combination of diodes and capacitors on the secondary of the transformer.
That's what I suspected. I've seen plans before for voltage-multiplier DC circuits to use as "stun guns". I'm pretty sure they don't work, except to annoy someone who already wants to hurt you. If you carry a weapon, you have to be sure your assailant can't take it off you, cos then you're really Donald Ducked.
Want to see this hooked up to the grids of an electric fly swatter, one with good spacing.
I used one of the smaller brothers of these to charge a capacitor the size of my upper leg. It was quite spectacular to discharge it according to safety regulations.
Funniest reaction since that firework farting Asian doll thing!
That resin potting also probably suggests stun-gun module otherwise there would likely be arcs across various components and the module would likely destroy itself.
2:00 in my country i would get more jail time then the burglar if i was to harm him even if he was armed this stuff is absolutly crazy
Finland?
these were quite the thing in 2017. still very useful even today for making stun guns.
I am not old enough to watch when he shocks himself
Stone Cold7 he died
he died... poor clive... now we have to go to ashens...
ForeverMan Did he lick it?
he didnt, thats something only Waterjet Channel can do now... go figure
just watch it
Clive. You crack me up!!! Your 'series' if videos are superb. Explained in a logical way so I can figure the stuff out. Many thanks.
Had to go re-watch don't taze me bro just for nostalgia
Geez, you are braver than I. I don't think I would have the nerve to stick my arm across a stun gun like that.
Man gets drink and shocked with a tazer, then doodles on a pad. Is it possible to make a rube goldberg machine of electronic bits?
The power supply in my Quad electro static speakers uses a small TX that gives about 600V then a rectifier then a diode capacitor ladder arrangement. The bass panels have about 6KV and the trebble panels about 1.5 KV on the grid.
Whoa ive never seen a PEGI 18 video before!
Thanks for taking one for the team, Clive
It's funny how it's illegal to defend yourself and it's OK to let yourself get stabbed to death or robbed in your own home
its the weak and crooked politicians working for satan that done this ,you see its easier for the darkside to carry out their plans when there is little resistance , look whats happening in america ,same thing looks to be in motion !
It's not illegal to defend yourself. And at least if these are illegal, it keeps them out of the hands of the people who want to stab and rob you.
You can get hold of these on the black market but they're very rare. I vaguely know, or have known, the sort of people who might be able to get this sort of thing. But nobody's ever actually shown me one. So the ban is pretty effective.
The thing about carrying a weapon is, you have to be sure your assailant can't take it off you. Cos then you're double-fucked, you've just armed the bloke, and he's incredibly pissed off because you tried to electrocute him. It's not like Arnie films where you make a sarky remark and he fucks off crying. The best defence is a good pair of running shoes.
But its not legal to get stabbed to death or robbed in your own home....
@@user-yw8sr3uj1w Well I'm sure the person who was stabbed to death will be thrilled to hear that.
I have one of these that is 800kv that I purchased from Banggood. They are not really for stun guns, they are used for igniting gas. Like the ignition for a gas stove or LPG heater. They can be used for pest control as well, like in a bug zapper.
I don't remember where I got mine (the one in this video) but keep in mind 800kv would be able to make sparks approximately 80cm in length. I can assure you these can't.
Yeah, there's no way its 800KV. Even the highest voltage power lines are less than that. Usually 400-500KV Max.
That is the rating that the product get's, but lets face it. More than likely it is 80kv. That makes more sense as a cars ignition coil is about 45 to 80kv depending on the ignition system.
It'd be nice to be able to connect one of these to an overhead power line, and pump in a higher voltage than they normally carry. For a brief moment, you'd be powering the National Grid.
dont worry BC here in new jersey in the US they consider stun guns as a real gun too.
GrayWolf rip freedom
Yep i can confirm i'm in NJ Airsoft guns are also banned.
The best first minute of any video you made
Hey! A European that agrees that weapon laws aren't blessings from altruistic government, and that maybe once in a while they have ulterior motives for doing that. We might not agree on what constitutes excessive, but we can agree that what you guys have is excessive.
The latest trend across "fly over country" where I live, is an end to the requirement to pass some sort of test, or background check before you can carry your firearm concealed, locked and loaded! North Dakota passed the law a couple of years ago, in South Dakota (where I have my concealed carry permit) the bill is setting on our very conservative Governor's desk awaiting her signature, is should come tomorrow. It is called by those who are trying to get this passed nation wide, the "Constitutional Carry Law. They are in hopes to get the law changed till it is the law of the land, and any man, or woman over the age of 21 can legally carry a loaded firearm on their person, in their cars, and of course in their homes. It should prove to be a good thing, in States that have had this law for many years, a sever drop in crime has been noted, especially in burglary, home invasion and car-jacking incidents. What criminal in their right mind would try to car-jack from someone who has the legal right, and ability to carry a loaded gun. Many of the States also have the "Stand your Ground" laws, so have no legal responsibility to run away from a fight when crime comes their way. I am sure these laws stand no chance in the coast areas of our nation, where liberal gather and wring their hands at the approach of freedom and personal responsibility, and that is where these slaughters that happen in the schools and such usually happen. Sure there was the one in Vegas, but that is an entirely different world from the rest of the US, and with all the people we have here, such shit is bound to happen from time to time, but overall we are a pretty much law abiding bunch, here in fly over country, where the sheriff can be 100 miles away, the cops 40 miles away, and the criminal at your window. We take care of our own, and our neighbors, sometimes it takes a handgun, sometimes it take an AR-15 but in the end, we do what must be done, when the shit hits the fan.
For many people asking = if this is powered but idle (ie the output circuit is open) then it burns quite quickly. Therefore you can not, say, connect it to a fence for squirrels and just leave. Perhaps some similar model would have this ability, but not this one.
These are only rated for brief bursts. I'm not sure what would be best for making a simple and safe electric fence.
Well if we don't see you again we know the UK police happened upon your channel and got evidence of you harboring a stun gun and using it.
Good channel 285K subscribers will miss you.
Tech note if you have a Hot Air station you can sometimes soften 2pt epoxy and some other potting materials letting you peel it out like snot, Set temp about 115-145f and heat just enough that it becomes pliable This also has worked for me with the Tar used to seal some consumer fireworks.
please do an teardown of Ikea's new power-bank called "Solbana" www.ikea.com/gb/en/products/lighting/batteries-chargers/solbana-charger-with-built-in-battery-black-art-60328575/
I live in America and I opened my sun gun. It has exactly the same module as that one. Except I run it off 9 volts.
I made a tazer build tutorial with one of these
I bought several of them and tried connecting 1 up to 2 charged 1860s in series and it was quite spectacular trying to get the longest spark I could out of it, but my fun was short lived and it died, never mind at least I have spares. They also work real well as cat repellents!
4:28 do you mean Schottky diodes?
i thought that at first, but there would be no point. fast recovery is more important in this case .there is no shortage of voltage which is where schottkys would be better.
The UK can say they do not want you protecting themselves against criminals, but its a matter of they don't want you having weapons to protect yourselves from them. They learned a lesson that started in Boston USA years ago.
1:49 Yup the UK self defense/gun laws completely suck. A great video nonetheless :)
Being safer than an American doesn't suck. Having to never even consider the possibility that one of my kids will get their head blown off by a bullied classmate is quite refreshing.
Rob Fraser True... Very true...VERY VERY TRUE :0
+Rob Fraser No they won't get their head blown off, they will just get their arms and legs blown off from a pressure bomb or be hit by a van.
+SpydreX Official Or get stuck by a kitchen knife, maybe we should ban those too and go back to eating with our hands. Being treated like a child by a nanny state government "naughty children can't be trusted with guns or any means of self defence" really does suck.
DavoTypeR e
Wow, the first circuit you drawed (3.33) looks like a mini coil emp circuit, it looks really the same except for the transistor.
1:01 - Peggy 18?
UK rating system I believe, like the US's E, T, M, AO, etc
PEGI* European game rating system. Like ESRB. PEGI 18 would be equivalent to rated M
Bryan Moore Also, for some reason RUclips is using those two rating systems in some of their newer video classification policies.
Ah, I kinda thought something like that. But the video played without any warning or anything and I see nothing in the video description. Thanks guys.
That's a totally different kind of video.
A CNC might help you opening such enclosed stuff… HINT HINT? Love your videos, thank you Clive!
1:28
God bless America! : )
Voltage triplers in series will work quite nicely. Radio shack used to sell them but dont know if they exist anymore.
I have a 9mm stun gun. The serious one is .45 ACP.
Is it fully auto, though, and how many rounds does the mag hold? Also, suppressed?
I've got the same or very similar one and it definitely is either HV multiplier or single very small flyback. I use it to power old NV goggles.
Stun gun classified as a hand gun? What a shame for a nation.
So is pepper spray. The only thing legal here is tiny cans of non-aerosol discharging Paint spray (because aerosols like Butane can cause asthma attacks and solvent shock/sudden sniffer's death).
Yet, I can legally own swords, knives, a shotgun, a .338 & .303 rifle legally.......
Yea...totally....sane....We need reforms in the UK for self defence.
S.A. Smith but if you use a rifle for defense you are basically fucked right?
No wonder why the news in the UK is so boring... would be great to see your news being as entertaining as the news from the USA... a mix of a horrible Reality TV show and 3rd person shooter.
S.A. Smith however if they become more common, I then have to worry about Joe Bloggs carrying one on the street when he gets pissed at my driving for no reason.
The issue isn't hardened criminals having access to weapons it's Joe Bloggs having access to them.
Look at 16 year olds with air rifles shooting cars. Dick's will be Dick's, let's not give them legal remit to be bigger Dick's.
S.A. Smith Who caused this? It's beyond me why anyone would make things this way.
There needs to be some political accountability imo.
Actually not, this is a power supply. I bought 4 of them and did make a stun gun. Put this output on a meter and scope and you will see that there is diode inside that charges a 2800pF capacitor which is across the output leads. When the voltage gets to the recommended arc distance, then the spark jumps. You can load this with some resistors in the megohm region and see that the output is DC. The recommend spark distance not exceeding 3/4" will show a charge of 13KV.
so if he put both output wires to his skin before powering the device it would not hurt ?
@@ash0787 Most likely not, there is very little current, I know if you are too close and the spark jump is small , it's not too bad.
Why am I watching a drunk gay scotman getting torrtured by electical devices?
Same reason I am baby ;)
yes they are stun gun moduels, used them as laser lamp trigger coils and gas furnace ignition module replacenents among other things.
