In this instructable, i will teach you how to make a very effective tazer out of a bug zapper .


Do not use this on anyone with a weak heart or pacemaker!

Step 1: Step 1: What You Need

Picture of Step 1: What You Need

You will need:
A bug zapper
A 9 volt battery clip
A soldering iron
9 volt battery
1 Blue led ( or any other color )
1 100 ohm resistor
1 220 ohm resistor
Hot glue gun and glue
Wire cutters/ strippers
Wall adaptor ( see image )

Step 2: Step 2: Start

Picture of Step 2: Start

Start by unscrewing the screws holding the handle together, make sure to keep these.

Step 3: Step 3: Remove the Zapper

You now have your very own mini-tazer

Step 12: Video(s)

Here are some videos of the tazer, I'll add one soon of me tazering my friend. ( it'l be great! )

Step 13: Random Fact

Did you know that taser stands for Tom A. Swift's Electric Rifle. Yes i know the title izzz wrong, but it sounds cooler!

I gave quickly ruined many pocket tazer by using them to make noise to scare the goats out of the feeder, ( they push and shove and knock the scoop out of my hand , knocking feed on the ground which they then won't eat) the tazer makes a great scary sound and they move away so I can fill the feeder. Will this tazer handle being set off in the air just for the sound?

mylsss (author)2016-09-01

If i want it to lessen the output voltage, what will I change or remove?

zain_de (author)2015-09-07

does it produce sparks or continuous voltage?

Varrma (author)2015-01-17

Can i put a more powerful resistor so that the zapping power reduces and it doesn't hurt much.

chala.ranjith (author)2014-09-28

how it hurts?

dillonxti (author)2014-07-22

try doing a flyback transformer taser


also I definitely could not do any of this without getting caught


what was the battery about?

freeza36 (author)2011-11-04

Can you just leave out the LED's? I am not necessarily the sharpest knife in the drawer when it comes to electronics. Plus i'd have to do it all without getting caught.

XOIIO (author)freeza362011-11-05

Yeah, I just threw them in so it looked cool, and was an obvious sign that it was on.

freeza36 (author)XOIIO2011-11-05

Ok thanks

lemonie (author)2009-05-11

I'm not going to download these videos 'cos they look a bit big - what bit rate did you save 'em at and how long are they? L

XOIIO (author)lemonie2009-05-11

well, you don't need to download it, just press open instead of save. I don't know for sure, I think they are 16 bit, I don't know what the standard is, they are each about 1 minute.

lemonie (author)XOIIO2009-05-12

I have to transfer the data from Instructables to my machine, which is a download (to me). At 1 minute each I think the bit-rate is higher than necessary ~1.5 Mbps perhaps, 512Kbps would probably do? L

XOIIO (author)lemonie2009-05-12

Probably, I don't have much experience with bit rate though.

frollard (author)XOIIO2009-05-14

just upload them to youtube, then you can a) embed them and b) save instructibles the bandwidth :D

XOIIO (author)frollard2009-05-14

I might, but it seems like too much of a hassel.

frollard (author)XOIIO2009-05-14

you already uploaded them to ibles - its 5 minutes work for the greater good of all humanity. :-)

XOIIO (author)frollard2009-05-14

ill try to do it soon, but i have a control freak mother. i hope that she ;ets me upload them to youtube.

natman3400 (author)XOIIO2010-08-12

Then, pardon my French, HOW THE EFF DID YOU BUILD THIS.

XOIIO (author)natman34002010-08-15

Meh, I was bored and I love electronics.

natman3400 (author)XOIIO2010-08-15

But how did your mom let you?

XOIIO (author)natman34002010-08-20

She didn't know ;)

natman3400 (author)XOIIO2010-08-21

That must have been hard

XOIIO (author)natman34002010-08-22

Not really, it was an overnight project.

freeza36 (author)XOIIO2011-11-04

My mom would be the same way. I might smuggle a bug zapper from my grandpas house.

eliasware (author)2011-06-29

what gauge wire??

XOIIO (author)eliasware2011-06-29

It was just some scrap from a radio or computer or something.

ARJOON (author)2011-05-20

could you reverse engineer this bug zapper and post it's schmatic it doesn't look so complex. or just take some pictures so that i do it myself. in Mauritius these things are illegal

tommiesmee (author)2011-05-10

i'd probably be better if you'd upload the video's to youtube, they load very slow this way.
i've been thinking of how to make a tazer, but never thought of using a bug zapper (never liked those). good idea! =D

Alex1M6 (author)2010-02-18

Will a 9v battery destroy any of the components if it was originally designed for 2 AA battery's?

XOIIO (author)Alex1M62010-02-18

Surprisingly it doesnt. I'm sure it puts more of a strain on it, but it functions just the same as with AA batteries. Let me know how yours works out.

Alex1M6 (author)XOIIO2010-02-18

Well I tried it and now the internal metallized polyester film capacitor has developed a huge crack and I can see the insides of the capacitor. It seemed to give more of a spark when running off a 9v but I dare not put the 9v back in in case it stops working all together as it still works fine off of 2 AA's.

Do you have any other tips on increasing the voltage? As I am trying to make a kind of "stun gun" that can at least arc through a thin layer of cloths.


XOIIO (author)Alex1M62010-02-21

Well electricity takes 10,000 volts to arc one cm, so it depends how thick and what you can afford. Taser probes are 5cm apart, thats why they say it has 50,000 volts, but thats only the arcing faze, once contact has been made it drops to 5,000 volts which is the cycling faze. this design requires open skin, so your looking at a hell of a lot more than a dollar store device. I would look into buying high-voltage capacitors, or use a coil-gun design as a tazer.

Alex1M6 (author)XOIIO2010-02-21

I would just go and buy a stun gun but they are illigal here in the UK for some stupid reason, So I am forced into making my own.

XOIIO (author)Alex1M62010-02-22

Thats too bad. Are you making yours for self defence? Why exactly do you need it?

Like I said, I would look into capacitor banks, but you would pretty much have a one use device unless you devised some on the go charging circuit,  and you would need a very high voltage to arc through clothing.

Alex1M6 (author)XOIIO2010-02-22

I don't really need one for specific reason, but It would be good to have one for some of the differnt projects I have planned which require high voltage.

I have already made a coil gun using 12 of those capacitors you get in disposable cameras hooked up in parallel and I have to say that when I shorted the out using the capacitor legs the spark it produced was bright and loud, there must be quite a bit of current!

I think I have found a way of upping the voltage by making and adding a step up coil at the end of the bug zapper as I have noticed through picture's of stun gun internal circuits on the internet they look very similar to my bug zapper circuit but just with a big step up coil at the end.

CoNiGu (author)2009-12-11

im just stuck at the end on where exactly to make connections with the resistors and the led, do the resistors need to be connected to a prong or just the switch and the led?

XOIIO (author)CoNiGu2009-12-15

The switch has 2 separate connections (4 prongs, two connections). The power for the tazer circuit is connected to one set, and the resistors lead from the battery to the switch, and then the L.E.D

CoNiGu (author)2009-12-11

if you could email me telling me all the solder connections that would be great or if you could post them up here,  my email is

XOIIO (author)CoNiGu2009-12-15

Sorry about the wait, I'll get to that tonight, I'll have to go over this again.

555mst555 (author)2009-08-10

oh crap...i just posted's excalt the same....!!i swore! but i really didnt get the idea from u....sorry ...coz i did'nt know u posted the same ibles....

XOIIO (author)555mst5552009-08-10

that's ok. I'm sure you didn't because that's an absolutely great way to kill your reputation. By the way, the "twisty wire thing" is a twist tie, and I would probably iluee a cable tie stead. And what you think may be rust is not rust, it is just the coating in the metal being vaporized. This is perfectly normal, I see it all the time. If you have any other questions or need help feel free to ask.

555mst555 (author)XOIIO2009-08-11

btw...what batteries does ur use originally....and what are u using now?

XOIIO (author)555mst5552009-08-11

well, originally it used 2 AA batteries, but a 9v gives you a much stronger charge.

555mst555 (author)XOIIO2009-08-14

so u just soldered a 9v clip?

XOIIO (author)555mst5552009-08-18


Kaiven (author)2009-06-15

I love this! clean and powerful, yet I do not know where to buy a bug racket zapper thing.

XOIIO (author)Kaiven2009-06-15

You can get them at the dollar store, or dollarama. You can also get them at hardware stores, such as Canadian tire or co-op hardware, but they use D Cells, and i prefer a smaller more discrete handle, and it fits a 9 volt well.

what is the amperage from this tazer
