Introduction: 2000V Home Made/DIY Stun Gun

Picture of 2000V Home Made/DIY Stun Gun

in this ibles u will learn how to make a some thing like a plastic baton+stun gun.


Step 1: Get the Stuff

Picture of Get the Stuff

all u need is:
bug zapper thing
2 pin plug
vice grips
heatshrink tubing
keeping/twisting thing(see pic)
some knowledge about electronics and common sense

all the stuff i use is legal....especially the bug zapper, which is rarely illegal in any country....even in my country.....where guns,swords,combat knives,explosives,pepper spray,stun guns,hand cuffs,thumb cuffs,leg cuffs,high powered lasers,airsoft guns lighter shaped like guns/pistols,real guns,live rounds,contraband cigarettes,drugs are ILLEGAL in my country....i live in the safest place ever.....on a ....i actually live in SINGAPORE.....oh ya country just turned 44 yesterday :)


Step 2: Open'em Up

Picture of Open'em Up

locate all the screws and unscrewthem

NOTE: some screws may be under a sticker

nce u opened it , u will see a circut board

IMPORTANT!!:"short" out the circuit before touching!!

keep everything! the 5 screws and the button in the other half of the handle

Step 3: Get the Ugly Crap Out

Picture of Get the Ugly Crap Out

next,pry open the tennis/badminton head out...u should end up with just the handle part.

u should end up with the parts that are not needed

Step 4: Make the Cool, Scary Tip

Picture of Make the Cool, Scary Tip

next, we wanna make the tip that scares most friends....using the 2pin plug

Step 5: Make Way!

Picture of Make Way!

first, file/cut/dremel in between the 2 pins so that u can screw it on later

Step 6: Scary Stuff

Picture of Scary Stuff

next, bend the 2 pin s together.......u will probably be left wit some's just fine!, get ur self some of the wire keeping/twisting thing(see pic) and get the metal

coil it around one of the 2 pin plug,making sure it's in contact with the pin u coiled around

next get another keeping/twisting thing(see pic) and some heat shrink tubing

poke a hole in 1/3 way through of the heat shrink (only 1 hole needed)

get the coiled keeping/twisting thing(see pic) and put it on the 2 pin plug....then put on the heat shrink,making sure it it sticks out throught the little hole u made earlier

next, add heat!


Step 7: Gonna Finish

next....just solder all the wires.....

the red wire on the circuit board - any one of the 2 pin plug

x2(black wire) on circuit board... - use only 1 of the 2 wires and solder to the other side of the 2 pin plug (using 2 black wires would be saferthought.....if some how 1 cable has problems)


Step 8: Assembly

Picture of Assembly

put everything back in and ....SUDDENLY it does'nt fit......then, get a jet lighter or some small torch and a big diameter screwdriver which cannot fit the screwhole on the assembly

light ur...lighter while pressing down the screwhole part of the whole assembly

this will melt the plastic into a sort-of L-shape

Step 9: Done....sort Of

Picture of Done....sort Of

once u screwed everything.....all u have to do now is test it out.....

BUT before u do that, u have to re-position the keeping/twisting thing so that it arcs to one of the 2 pin plug

don't put the keeping/twisting thing too close......u want it to arc every1 sec if the button is held down continuously

Step 10: I Applaud You

Picture of I Applaud You

u have just made a home made stun gun....NOT taser�"....... taser" is a brand!!

Step 11: ATTENTION!!

please do not test this great creation of mine on an will hate u

btw if u wanna test it on sure that they allow u to stun them......if not's just rude........i mean...u wouldn't like someone stunning u when u're drinking beer or doing ur work.....i would grab that thing and stun him back.....

Step 12: Word of Advice

after each use, by which i mean scaring them with the electric sure to discharge the thing or it still can stun ppl.....

Step 13: Voltage

Picture of Voltage

wanna check how much volts urs is gonna produce?

no prob....just take a look at a brown component on the circut board and read the printing


nutsandbolts_64 (author)2011-01-12

How come I didn't see this?!?!?! Mine only produces 500 or so volts. Still, it's circuit is incredibly simple. It uses a few diodes, one transistor, one mylar capacitor, and some resistors. Meanwhile, yours is a monster! Word of advice: check the miliamperage, anything beyond 0.06 miliamps can kill. Of course, it depends on where you electrocute yourself. Fingers are safe (duh). If you want to lower the amperage, just solder on some more resistors. It's gonna heat up though. Oh, right, connect a bridge rectifier circuit to it. It will turn it into AC voltage. Because, you see, DC contracts your muscles causing you to "suck", while AC does the usual electrocution you see on TV which pushes you away. It's kinda like force pull and force push if you ask me :P

a bridge rectifier alone is NOT going to convert DC into AC, for that, you need to build something that switches polarity from + to- and - to + very quickly, like 60 times every second, that's how you get AC. The purpose of the bridge rectifier that you mentioned is to convert AC current into DC by ignoring ONE polarity and not ignoring another one, effectively getting rid of the "Alternating" properties of AC and getting a "Direct" property of Direct Current (DC). For example, if you solder a bridge rectifier (the section marked ~ and ~) to a line connected to your AC 120 volts outlet, on the Bridge Rectifier output (the one marked + and -) you will get 120 volts DC (Direct Current) for which you can use to power a high voltage DC motor or any other DC equipment that requires 120volts DC, you cannot use a bridge rectifier to do the opposite which is what you suggested (converting DC into AC), if you want to achieve a DC into AC conversion, you can build a commutator ( a device that rapidly reverses DC polarity by use of a spinning shaft connected to a DC motor with the appropriate differentials linked through two spooler (one bigger where the commutator rotates and the other smaller where the DC motor spins the load) you will need to calibrate the commutator to 60hz (60 cycles per second) to operate most 60hz AC electronics)

Wouldn't an inverter be an easier option to turn DC into AC.

I have one fitted in my work ute.

Turns 12VDC into 240VAC, with a 5kw capacity, though I think its a bit bigger than I really need , and besides ....

VA in = VA out...right,

so 5kw on 240 volts = (5000/240)Amps = 20.8 AMPs Secondary winding

5KW on 12 Volts = (5000/12) Amps = 416 Amps Primary winding.

I think my car battery would melt..... !!!

A commutator...? really...?

Wow man, 9-month old comment. You probably should realize that if comments were posted 3 months beforehand, the person(s) would have probably figured it out by then.

so true. i would'nt be bothered to post by then.

I did a bit of digging, my bad, bridge rectifiers turn AC to DC, not the other way around. Although I soldered mine the wrong way and accidentally turned it into a 2x voltage multiplier! I'm not really all that sure why it's like that, but here's my failed bridge rectifier that actually doubles the voltage! Can anyone explain this to me? It has no logic to it in my mind; it's so weird!

Where do i get an electronic bug swatter ???? I live in usa

STEDMARS (author)2014-07-20

hey need help finding the negative power input for the 12V battery

STEDMARS (author)2014-07-20

hey i found this stun gun and i can;t find the negative input for the battery

jx88 (author)2012-12-05

hi, im from sg as well. hi five.

plasasesamo22 (author)2012-11-03

I have a question...
Can i have more voltage at the output?
How can i do that?
Its just because i want a bigger spark
And i saw on internet taser with 7.6 MILLION VOLTS!!
Its that possible?!!
Tank you!

tesla man (author)2012-07-06

So, does this make a constant spark, or only when you touch it to objects? Also what is the length of the spark?

555mst555 (author)tesla man2012-07-08

it makes a 'constant' spark. it will take a few mili second or so to 'charge up' when u press down on the button continuousy, very much like stun gun. When in contact with an object, no spark will be seen, as there will be contact between both terminals. The spark length is only around 1cm.

gonzowizard (author)2012-01-13

I built one of these things, but it has a couple of annoying limitations. Is there any way to make it give off a continuous arc or go through clothing? Otherwise, these ibles should be titled "dangerous shocking toys" instead of stun guns.

munaib rumjaun (author)2011-11-13

plzz just help me
when u add the 2 wires one black and one red
u connect one of each wire to the front of the mobile charger
then what do u do with the other 2 wires??

555mst555 (author)munaib rumjaun2011-11-14

red wire from bug killer goes to one wire of the moblie charger.

the black wires goes to the other wire of the mobile charger.

it will be an open circuit. only when u make the 2 point of the mobile charger get in contact with somethign or someone, then i'll discharge, or incapacitate them

XOIIO (author)2011-08-09

Yeah totally not 2000 volts, on 3 volts this thing puts out 300 volts, and it looks an awful lot like mine, plus you straight out say that this is all your idea, i call copycat

jdash (author)2011-04-16

what exactly do you mean 'short out the circuit' ?

555mst555 (author)jdash2011-05-17

make sure there's no more electricity in there so that it's safe to handle. trust me, this step is trial and error. you WILL accidentally shock yourself.

mnoonan504 (author)555mst5552011-08-03

cross the leads of the capacitator - the large cylinder with as few numbers ending in uf. place an insulated screwdriver across the leads and if any voltage remains you'll see sparks and pop. be careful wear gloves.

fub1985 (author)2010-10-14

in theory if you were to double the battery input would that tecnically double the output? say for instance if 2x 1.5volt AA batterys produce say 2000v would that mean that 4x 1.5volt AA batterys will produce 4000v?????

JohnMichael (author)fub19852011-06-29

No, it goes through a capacitor to build up the higher charge. The output is limited by the capacitors limits. Doubling the battery input may get it to charge faster (and discharge faster) but the current will not be higher. That might be achievable with a second capacitor, but it seems unnecessary.
I actually did something very similar to this Instructable. instead of a two prong plug I ground down some nails and built my own contacts (and did not have to heat the plastic. I don't get the sparks on mine because the prongs on mine are further apart. However, it hurts like hell and would definitely make someone wary of risking getting zapped a second time. The biggest drawback to this design that I see is that someone who knows what they are doing could easily take it away. I think that problem would be solved by moving the button switch closer to the front end.

555mst555 (author)JohnMichael2011-07-05

true. i kinda regretted bending the 2 pin plug, coz when i...(stun myself) it's more of pain, rather than muscle in capacitaion. i'm guessing this is coz the prongs are too close, probbably, cooking some meat?haha

and about the drawback, u think pasting aluminium tape at the sides would work? 2 strips of alum. tape, down about half the lenght of the stun gun. 1 strip to +ive and the other to -ve

555mst555 (author)fub19852010-10-14

hmm...i'm not sure bout that, but i have switched the original battery (3v) with a cordless phone (3.6v) battery. and it seemed abit stronger,BUT the battery went dead very fast.I guess just swapping the batteries wont make much difference unless u change some stuff on the circuit board.

darylemmanuel (author)2011-06-14

increasing the input would in no way increase the output...the 2Kv capacitor will only charge rather faster...m from India and we too have the same zappers here...

hazblitz (author)2010-04-11

They are illegal in Australia!!! Customs are very strict on these fly zappers... now I think I know why ;-)

coolfordy (author)hazblitz2011-04-11

hmmm that's interesting i got one from a local $2 store but it was $6. you should give that a try if you are still looking for one

555mst555 (author)hazblitz2010-04-13

lol...weird....i've never heard that they were illegal before 0.o

ajazzypancakes (author)2011-03-03

instead of a 2pin plug, i used to screws wired, it works good but i cant get it to arc, it only makes a tiny spark when it comes in contact with the object that im tasing, please please please respond, i dont know what to do

yonex (author)2010-11-05

imade my self a taser similar to yours mine too is 2000v

2000v for two AA batteries 800mah
if the mah of the battery go up does the voltage will go up to???

555mst555 (author)yonex2010-11-06

hmm. i'n not sure bout that. The only way is to test it on :D

MoshBoshKid (author)2010-08-23

ive made it all but i dont seem to be able to get the arcing. i know im using a differnt swatter to you so that might be the problem :(

555mst555 (author)MoshBoshKid2010-08-25

hmm...try bending the 2 prongs closer together.but not too close, or it will arc too much, which is not cool and not good for the bug zapper.

OXI2vasyl (author)2010-08-12

lol it has very low amperage, once took a shock to those in the market, I jump with fright because of the noise, but not feel anything (I was already thinking that I had no hand) rofl

jggammer (author)2010-06-17

not 2000 barely 200 it even says on the wraper of the fly swater 200 do not disesemble!

555mst555 (author)jggammer2010-06-18

oh....maybe u used a different brand

deathnote_213 (author)2010-04-22

can this thing can kill a catfish??? ASAP pls..

555mst555 (author)deathnote_2132010-04-24

erm...i guess..coz if it hurts  human  i'tll definitely hurt an animal more.....but wth do u wanna kill a catfish?

deathnote_213 (author)555mst5552010-05-02

cause we have a restaurant and we serve foods like catfish and catfish taste good went you kill it the day he will be cook but when my father kill it its very inhuman my father use baseball bat to kill the fish and it really  looks bad.. i made one but i never tried it can u try??  hehe....

555mst555 (author)deathnote_2132010-05-02

0.o....i thought cat fish has some poison or something?

yusuf786 (author)2010-01-31

hey u say u from Singapore rite...well i also anyway where u buy the zapper coz i coudnt find one...! :)

555mst555 (author)yusuf7862010-02-03

yeah....u can buy at japan home or mustafa centre.....can buy at some minimart ah...bud must ask

yusuf786 (author)555mst5552010-02-03

oh ok thanks buddy...! nice instructions by the way

tezakuri (author)2009-08-22

rise battery voltage til 5V will see high voltage spark and hear the sound....

555mst555 (author)tezakuri2009-08-24

do u know how many amp can kill a person?

SaNjA2659 (author)555mst5552010-01-03

6 milliamps coming trough heart can kill a human!

Jodex (author)SaNjA26592010-01-22

Or wasn't it 60 milliamps...?

SaNjA2659 (author)Jodex2010-01-23

Oh, I don't remember... But I think 6. You can google it or read in
