Introduction: 9 Volt Secret Taser

Picture of 9 Volt Secret Taser

First off, i know conrad2468 made a similar one(hint hint "similar").
His uses only 9 volts, mine uses 330v or close to it. and my whole approch to it is differnt
last but not least i must thank rwilsford07 for the charger plans.

Well here it is a small secret taser!

Step 1: Supplies

Picture of Supplies

What you need
1. (1) 9volt battery
2. (1) disposable camera
3. (1) capacitor charger (made from camera). go to rwilsford07's coil gun instructable and its in there. there are instructions for a simpler one later on.
4. (1) AA battery and battery holder
5. (1) 9volt battery holder
6. (1) switch
7. soldering iron and solder, needle nose pliers, electrical tape,
and wire
the 9volt battery holder, AA battery holder and switch can be found at radio shack.

Step 2: Battery

Picture of Battery

For the battery all you need to do is take out all the insides.

you do this by using your needle nose pliers to pry back the bottom and take out the bottom cap. then you push the top cap out the bottom and cut the connectors.

you can throw away the insides or use them as AAA batteries.

Step 3: The Capacitor

Picture of The Capacitor

to get the capacitor you are going to need the disposable camera(you can get these free at wal-mart. ask for the used ones.), soldering iron, and pliers.

1. open the camera and get the chip board out.
2. discharge the capacitor by touching the two leads together with your pliers. you should see a spark on contact. after that it will be safe to touch. make sure you take the battery out.
3. you can either desolder the capacitor out or just cut it out with the pliers. cutting it out is easier.
4. if you dont want to make the smaller charger. the next step will tell you how to make one alittle simpler.

Step 4: A Charger

Picture of A Charger

alright. now that you have the capacitor out your going to need a charger.

All you have to do is solder in two wires were you got the capacitor out of. wal-la now make sure the wires are out of the casing when you put it back together. connect the 9volt battery holder to the two wires. make sure you get the polarity right.

Step 5: Lets Put It Together

Picture of Lets Put It Together

all you need to do here is solder the leads to the top cap. make sure it is negative-negative and positive-positive.

also the leads must be straight and the total length cant be longer than the battery casing.

Step 6: Charge

Picture of Charge

test the charge to see if you got the polarity right. (be carful this is dangerous: dont touch any of the metal).
If you dont hear a noise getting louder then you got it wrong.

Then discharge and put some electrical tape over the capacitor and its leads.

Step 7: BOOM

Picture of BOOM

finish up

1. put the capacitor in and it should look like pic one.
2. stuff some tape or whatever you can (not conductive) put in and then colse it up.
3. put the bottom cap back on and bend the metal back into place.

Step 8: Safety

Remember this project uses electricity so anyone with a weak heart should stay away from it.

Please tell which type of capacitor it is used here. Tell it's full name .

hyudryu (author)2010-03-22

Wow your friend is stupid. 9VDC does nothing unless hes going to shock a slug...

Dilong_paradoxus (author)hyudryu2010-08-15

It's using a camera flash capacitor stuck into a 9V battery case. The capacitor stores a very large amount of energy... ...and besides, 9V isn't even enough to injure a slug. Try ants. :D

wolf996 (author)Dilong_paradoxus2012-10-29

Try Salt ^ . ^

Or if he plans on zapping his tongue.

peyton14 (author)Mr.Stein2012-06-03

i like zapping my tounge :(

d1ndian (author)hyudryu2011-06-04

i once accidentally shocked myself , using a ceiling fan capacitor, it was awesome. also my power source was home power outlets in india.

fogter08 (author)2009-10-07

i've kinda demolished the 9v battery to get to the inside, haha, well uh, what would i do if i just have this rubbery thing with i'm guessing AAAA batteries? i've shocked myself like 9 times with it so far

emorulz (author)fogter082009-10-12

are you talking about the insides of the 9volt battery?

wangtrevor (author)emorulz2009-10-16

wait, isnt the insides of a battery alkanine and isnt it poisonous?

-max- (author)wangtrevor2011-05-04

yes, you get 6 batterys that are even smaller then AAA batterys. there called AAAA (um, AA, AAA, AAAA!)

RiddlywalkerB (author)-max-2016-10-23

my hearing aid uses "EH?" "EH?" batteries.....

codongolev (author)wangtrevor2009-10-18

 not 9 volt ones. they've got little AAA sized batteries ( they're a little smaller, but they work) inside.

-max- (author)codongolev2011-05-04

there called AAAA batterys

codongolev (author)-max-2011-05-05

Yeah, they're called AAAA batteries. I didn't know it at the time. now I do. :)

Colonel88 (author)wangtrevor2009-10-22

Only the Energizer brand batteries have AAAA batteries (REALLY small)

-max- (author)Colonel882011-05-04

ang duracell too. i know for a fact because a actualy took one apart.

account3r2 (author)Colonel882010-10-16

23a are much smaller (i think) and have more volts

Guys, an advanced version of above project.

Please view and like the video if you really like it. Honest comments over it are always welcomed. It would be helpful for this project and our college. Thanks for your time:-)

1.5 Volts can do a very large amount of damage-look up ultra capacitors. batteries, even though they have a very large amount of energy stored in them, cannot do much damage because they have what is called internal resistance, making it impossible to for them to transfer many amperes of power at a time. But, with the right supplies, (such as an ultra capacitor) 1.5 volts can melt metal.

wolf996 (author)rocket master2012-10-29

Yeah I Made One In Chinese Class And Melted The Table Leg In A White Hot Flash

An Ampere is a measure of current, not power. You mean Watts.

J-Ri (author)rocket master2011-05-29

1.5 volts does nothing to a human, it has nothing to do with the internal resistance of the source. Look at a car battery for example. 12.6 volts at full charge, the average one is capable of putting out 600 amps and staying above 10 volts while doing it, larger ones in light duty trucks and SUVs can put out over 1,000 amps. They will melt a wrench (I'm told), because the wrench has almost no resistance. It's primarily the amperage that makes the metal hot.

We humans have internal resistance too, IIRC mine was about 600,000 ohms gripping the leads as tight as I could. Using ohms law, that's .000021 amps, and trust me, you don't feel that!

-max- (author)2011-05-04

its propibly a god idea to add a switch to turn it off so you can put it away and turn it back on to 'arm' it

FrozenIce (author)-max-2011-11-26

smart... he must be a cyborg!! GET HIM!!

wolf996 (author)FrozenIce2012-02-26

Oh No!!! The Up Rise Has Already Started!!!

peyton14 (author)wolf9962012-06-03

dude just hack open a lithium battery... wear goggles and gloves

dume (author)2010-01-07

soooo you put a pic on th front say 9v plr plr plrits all ways like more after the frist pic

Mr.Stein (author)dume2011-12-20


The nerdling (author)2011-03-31

i have 4 of the camera capacitors and another huge one >:-E

emorulz (author)The nerdling2011-03-31

You should make a cap bank and then an awesome coil gun!!!!!!

TehMessiah (author)2011-01-09

... brings a new meaning to 'Put your touge on the battery' then

Hakman (author)2010-12-26

Slugs naturally have salt on their skin???? Wouldn't that like hurt them or something?

Dilong_paradoxus (author)Hakman2010-12-26

No, because it's incorporated into them. Table salt in large quantities placed on a slug puts the salt were the slug's body doesn't want it, in a form it doesn't like.

Dilong_paradoxus (author)2010-08-18

An AA? Brilliant. :D Lower resistance lowers heat, so it wouldn't do much.

kagflab (author)2010-02-19 make the charger you put in the leads of both the 9V connector and the AA conector into the capacitor holes. you can also add in a button (i diidnt but reccomend it) 

NeMewSys (author)2009-02-13

Omg the video... will that burn my skin?

bambam95 (author)NeMewSys2010-01-21

I did this and it burned a hole in my finger

emorulz (author)NeMewSys2009-02-13

no. it just gives a quick and nasty shock.

NeMewSys (author)emorulz2009-02-13

Have you tried it? :P

emorulz (author)NeMewSys2009-02-15

yep. many times

AKskate907 (author)emorulz2009-12-01

emos always hurting them selves, nice Instructable though

emorulz (author)AKskate9072009-12-02

lol. thanks

lunchboxslayer27 (author)emorulz2009-05-23


LILhazY (author)emorulz2009-05-24

i no ueed a capacitor but can u get it from somthing diffrent apart from a disposable cam. i mean its not hard 4 me to go out and get a dissposable cam but is there anything else that i could rip it out of something maybe lying round the house? I.E old stereo,old walkman radio,
