Intro: DIY Taser +30,000VEver wondered how fun it would be to zap someone with a taser? Now you can. :DIf you follow the instructions you should be able to get a good shock out of this that not to lethal but I'm sure its not that hard to step this up from a good shock to apowerful weapon so be responsible with this and use common sense when choosing who to shock (don't go around shocking old people, small children or any one with aheart condition its just a bad idea).Now that thats out of the way the taser we will be building sends out about one shock per second probable around 35,000-40,000+ volts at an estimated .01 milliamp(millionth of an amp) the shock is about enough to cause you to jump back a few feet if your not expecting it. Voltage and amperage are estimated since i don't have theequipment to accurately measure it.

P.S. sorry about the low quality pictures and bad lighting my good camera was KIA I'm working on getting a replacement camera to take better pictures

UPDATE: i got a new camera enjoy the high res pictures

Image Notes1. come get some

Step 1: Parts listmost of the parts cam be found at radio shack or a hardware storeElectrical Portionignition coil 12v - you can get this from an old car at the junk yard for about $5. for this project you want to get one with only 2 leads. these come in all shapes and sizesso you may have to ask the people working there to help you. also try to save the mount you'll need it later but its ok if you cant12v relay 12v relay - radio shack should sell this1000 u Farad capacitor 1000 u Farad capacitor1 u Farad capacitor 1 u Farad capacitornon conductive switch- i made the mistake of buying a metal switch and get shocked every now and thenwires- with descent insulationelectrical tapewire capes12v power source - i used 8 D-cells for thissoldering stuff

Mounting components2 foot long, 1 inch thick, 2 inches wide board6 inch long dowel 1 inch widesmall screws

Image Notes1. note the positioning of the leads on the relay since the wiring diagram doesn'thave the leads labeled just the location of the leads


Step 2: Wiringnow that you've got all the parts we start attaching 6 inch lead wires to all used the leads on the relay this will make your life simpler. connect all the wires as shown in thediagram when you finish connecting everything flip the switch to on and touch the line out and negative line out wire. if you did it right you should be very awake(AKAshocked).UPDATE:3/11/08right so i was going through and looking at this and i though I'd add a small section on whats happening here with the wiring just to clear things up.1)The switch is flipped completing the circuit.2)The the relay is closed and the 1 u farad capacitor and coil begin to charge while the 1000 u farad capacitor simultaneously charges3)when the 1000 u farad capacitor becomes charged the relay breaks the connection and the coil and 1 u capacitor discharge shocking what ever may be touching thecoils line out and the negative line out4)the 1000 u capacitor discharges and the cycle repeats at step 2 through 4 until the switch is flippedUPDATE:6/6/08ok so imagine this is your panel on the back of the relay

- 1 - 2- 3 - 4- 5 - 6| 7 | 8these numbers should be printed on the relay however may be missing

when positive and negative are connected to 7 and 8 the relay should tripwhen no current is running through 8 and 7 relay allows electric flow from {1 to 5} and {2 to 6}when current is flowing through 7 and 8 the relay triggers switching the connection from {1 to 5} to {3 to 5} and {2 to 6} to {4 to 6}if all this is true with your relay you have the same type of relay other wise you may need to rewire stuff

next 8 and 4 connect to the large capacitor on the negative side (side with NO indentation running around the rim.) 5 and 7 connect to the other side of the largecapacitor.

1 connects to the positive side of the small capacitor and 6 connects to the negative side.

2 and 3 connect to nothing

other things to check look for shorts around the relay theres a lot of wires really close together

Notesthe different colors of the wires is simply to make it easer to differentiate the wires from one anotheryou might consider using a larger capacitor in place of the 1000 u farad capacitor since i noticed the coil isn't fully charged when it discharged so the resulting shock islike rubbing your socks on the carpet and touching something metal as opposed to sticking your finger in a wall socket.


Image Notes1. not used2. not used3. the colors of the wire mean nothing i just did it to help distinguish the different wires

Step 3: Mountingby this point you have all the electrical components so your able to mount it how ever you like but this is how i did it. Mount your coil 4-6 inches from the front of the 2*4using the mounts you salvaged from the car if you weren't able to salvage it use zip ties or duct tape. Next mount the 6 inch dowel 1-2 inches from the rear of the coil. forthe batteries i mounted them on the bottom of the 2*4 but this does not work so well you can do it that way or try to come up with a better way to mount them. the switchwas also a little tricky since mounting it to the dowel would be hard. for this step i mounted the switch to the side plate on an old pair of safety glasses then mounted thatto the dowel. Finally you should have about a foot on 2*4 left this is there to counter the forward weight of the coil on mine I attached a string to help keep it level.

Notesthe batteries were falling out so i have since added a hinged section of plexiglass with a small latch

Step 4: All the wiresfinally you should have a bunch of loose wires hanging off use the electrical tape to help consolidate the wires so they don't snag on any thing then your done.have fun zapping people.

snowluck2345 says: Jan 29, 2011. 10:59 AM REPLYbasically everything, that doesn't have any thing you need for this.

lrjblaze says: Dec 5, 2010. 6:13 PM REPLYhello!just wanted to know what would be the resulting effect of this taser shock? i mean, how bad will it hurt?

z0tx says: Nov 24, 2010. 12:32 PM REPLYIs this stronger, equivalent, or less powerful than a Disposable camera with flash built tazer?

Amix9 says: Oct 22, 2009. 5:05 AM REPLYHey,

I've reached ur taser invention b/c i was looking for something to light up my Spud Gun. I've been useing hair spray and even just pure Butane gas and thespark lighter on 3V didnt work.... So here i am for the 30kV.I have a few questions about it :

The capacitors are 1uF and 1000 uF, but at what Volts?How come u charge them directly from the batery and in other guides they need a charger (liek this http://www.instructables.com/id/Coilgun-Handgun/ i wanabuilt it too), and works on almost the same tech....Tasers are made from photocams and need the charger...Whats with soo many bateries ? Its a total of 12V ? or each ...Can it get me killed ? :)) .... very importantThnx AlotAlex B

autonomousoperations says: Oct 23, 2009. 8:58 PM REPLYthe capacitors i used are 50 volts and 35 volts if i linked to the right part when i made this. not sure why other guides use a charger i have chargeddirectly from battery's before and it was a convenient solution for this. you could probably substitute 2 big 6 volt batteries but you do need 12 volts, thebatteries are taking the place of a car battery. the total battery output is 12 volts (1.5 volt d-cell * 8 = 12). the shock from this is the same as the shockfrom a spark plug on a car maybe a little worse. the only way this could kill you is if you had a heart condition and ran the voltage threw your heart or ifthe pain.shock scarred you to the point of having a heart attack. if you are a healthy 9 to 40 year old potato canon building guy then don't worry about itto much.

on a different note it you are planing to use this to ignite fuel the design that this device uses does not provide an optimal shock for ignition. I have usedthis to ignite paper socked in lighter fluid but if you you the design i am attaching as a photo them you could get a much more powerful shock with thetrade off of refire time.

lrjblaze says: Aug 7, 2010. 4:17 PM REPLYhow many volts does THIS taser give off? is it 30000 like the featured instructable?

autonomousoperations says: Aug 8, 2010. 1:45 PM REPLYIt should be around 30,000 but the exact voltage depends on the coil you use. I don't have anything capable of measuring the momentary voltageso I had to use technical data from similar products to estimate.

Amix9 says: Oct 24, 2009. 4:51 PM REPLYThnx for the answer :D

I'll try ur design for the igniter .... (same car coil btw) hope it will work .

electridanger says: Aug 4, 2010. 2:10 PM REPLYdude make one thats conselable

BlueX273 says: Sep 30, 2009. 9:21 PM REPLYThis is awesome! Yet this is beyond overkill!!! You could kill someone with this! I mean, 2000 volts is enough for fun and self-defense, but 30,000 VOLTS,yuo have to be kidding!!! But great job anyways. =)

bighead5454 says: Jul 20, 2010. 12:12 PM REPLYvolts dont kill you can have 3 million volts and you couldnt kill amps are another story


autonomousoperations says: Oct 1, 2009. 12:04 AM REPLYit's not the voltage that kills people its the amperage. plus its and instantaneous shock that repeats every .75 seconds or so. with self defense tazers youhave a continuous electrical current which still takes up to 10 seconds or longer to take some one down to a point where they cant move

BlueX273 says: Oct 3, 2009. 12:49 AM REPLYActually, it takes more than amperage to kill someone; the voltage decides. For example: 1.5 volts at 0.1 amps isn't enough, but 30 volts at 0.1 ampswill kill you. Therefor, amperage is dangerous and voltage increases the danger. Also, when I said "You could kill someone with that!" I really mean"Shock them so hard that they pass out for awhile".

autonomousoperations says: Oct 3, 2009. 2:11 AM REPLYok and some people pass out when they get a shot or give blood etc. i could hold onto the discharge points and over power the impulse to let goit hurts a bit it will make you jump if your not expecting it but its pretty safe if you only let it get you a few times. besides its barely 0.01 milliamps.not amps.

BlueX273 says: Oct 3, 2009. 8:42 AM REPLYOkay, okay... Never mind.....

Kin_Hell says: Oct 4, 2009. 5:33 AM REPLY:L its funny you calling it amperage its called current Gtfo noobfags

micromuffin says: Oct 6, 2009. 3:39 PM REPLYThe proper term could be either. Toddlers use "current" and scientists use "amperage". You are clearly a toddler with grammartrouble.

coolchris1225 says: Aug 22, 2009. 9:51 PM REPLYDoes it arc... How long of an arc?

autonomousoperations says: Aug 23, 2009. 10:53 PM REPLYIt creates an arc of about 2 cm for a instant and it discharges 1.5 times a second. These numbers are from memory since I threw it away when I moved

coolchris1225 says: Aug 24, 2009. 8:47 PM REPLYthrew it away !?!? why didn't you give it to me? :)

mr. clean says: Mar 16, 2009. 6:11 PM REPLYI like how it zaps through clothes

doityoureself says: Mar 14, 2009. 11:02 PM REPLYI would not ever advise anyone to use a 12 vDC device to assault or defend themselves from assault. All you will do is make someone mad enough topossibly really hurt or kill someone. You are only producing around 30-40 DC amps at the very maximum, for a short duration and at very low reserve powerunless you had a car battery with it. Be careful who you use these on, someone who is determined to hurt you cannot be stopped from a 12 vDC coil! Itwould probably just make things worse if they were serious about hurting you unless you were faster and immediately high-tailed it from the scene and neverseen them again. The only device that I have been able to make to stop someone is made from 120/240vAC capacitors (along with many othercomponents). Many slight disadvantages though, like only one shot before needing a re-charge from 120/240vAC power supply source(unless you havemultiple capacitors,etc.), need to find way to keep charged for more than 48 hrs(capacitors drain off eventually, some quicker than others, depending onenvironmental conditions, etc.), very, very deadly(do not play around, treat capacitors as if they are charged unless you discharged yourself). And must haveexactly the right type capacitor/s and a way to efficiently deliver line to ground (or ground to line).These are a lot more complicated than a 12 vDC shock andI am afraid if I post it it may hurt someone. So in all seriousness be careful who you shock with 12vDC or 120/240vAC even if for different safety reasons. Iespecially hope nobody's serious about defending themselves with a computer mouse size homemade device, don't take me wrong I do admire the thoughtand ingenuity to fabricate such a device, I just hope you are not depending on this in a life or death situation. This is how great inventions/inventors aremade, so by all means, dont stop.

mr. clean says: Mar 8, 2009. 7:55 PM REPLYhow many people have you shocked? and has anyone needed c.p.r. due to the shock from this, or been seriously injured.

autonomousoperations says: Mar 9, 2009. 12:27 AM REPLYI've shocked myself accidentally more times then I can count well monkeying. I've also shocked about a dozen people in addition to myself but most ofthem only once since its not exactly fun to be shocked. no one has ever needed CPR the worst shock you usually get is enough to make you pull yourarm away uncontrollably or jump back uncontrollably with some singed hairs at the point of contact but singed hairs aren't common. To be safe just don'tmake the electricity flow threw the heart.


mr. clean says: Mar 12, 2009. 3:33 PM (removed by author or community request)

mr. clean says: Mar 12, 2009. 8:42 PM REPLYalso does your coil get warm when you use it, or is it because i have mine arc to to negative?

mikemmcmeans says: Jan 21, 2009. 9:11 PM REPLYthe factory line outs o the ignition coils have a lot of resistance in them. pop it off get some 10ish gauge wire wrap it twice around the output then lead it tothere ith other line out was

Xellers says: Jan 3, 2009. 2:42 PM REPLYPlease post schematics of this thing rather than the wiring diagram that you have. Different relays have different pinouts, so this might not work for everyoneif they use your diagram. Also, can you post an explaination about how this thing works for people that don't know?

seabeepirate says: Dec 23, 2008. 4:23 AM REPLYWhat voltage capacitors are you using? 12v? You may be able to slightly rework the circuit to use higher voltage capacitors... they would probably charge alittle slower but they'd give more of a kick I think. I'm not exactly an electronics expert, and in all actuality I don't think I would have put the time into thisproject to design the circuit. I'm more of a mod-it kinda guy than a build-it-from-scratch kinda guy. Ironically when I build something from a modified design, Iusually build it from scratch haha.

ReCreate says: Dec 19, 2008. 7:11 PM REPLYouch ouch ouch! Im not shocking myself anymore

Lonewolfajk40 says: May 29, 2008. 9:52 AM REPLYOk, So I had all the parts, tried over and over, got upset and resoldiered every wire, went to hook it up an he capacitor blew =( I just want this thing to work,why wont it????

Berkin says: Nov 4, 2008. 10:54 AM REPLYDude, you could make a much simpler "Super Taser" by connecting a 12v battery to a relay oscillator, which will send a pulsing current to the primarywinding on an induction coil. For the coil, I suggest 100 windings for the primary, and 1,000 for the secondary. Then, use the two wires coming from thesecondary as the probes. Big spark. HUGE shock! Although, I am not liable for whatever you do with it, so I advise you to take caution handling it.

autonomousoperations says: May 30, 2008. 9:52 PM REPLYhmm the capacitor blew... the small one or the big one? cause the batteries shouldn't have enough voltage to blow the capacitors to blow the capacitorso the only thing that might have caused this is the positive charge shorting into the rest of the circuit one thing you can do in the short term is hook yourpower supply directly to the coil you wont have the repeated shock you get with the relay but you will get a nice shock out of it even if its shorting back into the circuit

Lonewolfajk40 says: Jun 2, 2008. 11:30 AM REPLYI'm using a 12v rechargable battery in place of all the D batteries, and it was the 1000uF capacitor that blew :( I'm using a cool looking switch (red,lights up when you flip it on), could that be messing things up?

autonomousoperations says: Jun 2, 2008. 6:05 PM REPLYok so judging from the specs the battery shouldn't have enough volts out put to blow the 1000uf capacitor theres a chance the relay doesn't usethe same wiring scheme which would allow the high voltage from the coil to travel directly into the capacitor ill take a closer look at just how therelay is wired and Produce a more detailed wiring plan.

Lonewolfajk40 says: Jun 3, 2008. 8:56 AM REPLYSweet dude, thanks. I'll be waiting, and going out to find another capacitor >
