Build a World's Smallest Electronic Shocker! version 2.5

It is good to know if the tiny shocker is on or not, by adding a wonderful invention called the "LED", so you don't risk get bitten by the shocker again!

Disclaimer: This shocker can be dangerous if used improperly, it gives out about 400 to 450 volts, so I am NOT responsible if you or anybody are injured or killed by the shocker, the responsibility is yours...


Improved instructable!
I have been asked by comments and email how to attach a LED to a shocker to indicate it is on. So I then decide to make another instructable how to do that.

And, I have copied and pasted everything from my original shocker instructable onto this instructable and greatly improved the text on every step, also added more steps and replaced some pictures. I am hoping it would be less confusing to you and understand the project better so you can have an higher success in completing this project. :-)

If you do find anything confusing or an error on this instructable, please let me know and I'll fix it.

Step 1: What type of disposable camera should I use?

  • The best disposable camera you can use for this project are the "Boots" or "Polaroid" types, because they have everything you need.
  • The "Kodak" type is a bit more difficult, you need to find the type that uses an LED indicator, NOT a neon bulb indicator, those types will not work. Also, the LED type cameras uses SMD resistors, so you will need to find or buy one 220 ohm and one 100 ohm resistors.
  • All other types of cameras like "fuji" ect. will not work because they have an different and/or more complex circuitry.

Would this work http://m.ebay.com/itm/321095009296?cmd=VIDESC for the transformer

Hi what type of diode is being used because I'm buying my parts separately

Name of the diode?

Can i used D965?
thanks in advance :)

do you know where i can get these disposable cameras other than buying one ($9.35 at Walmart!!!)

Divergence1 month ago
does the disposable camera have a battery housing/holder that could be used for this?

can you use the other capacitor? because then you'll get way more power!

and does this charge then shock you or continuously shock you?

can you make instructions on how to attach a momentary push button?

A great disguise is a small mint tin; I used one from starbucks. You can fit all the components inside, including the battery. I affixed the leads to a 9v battery connector. When you flip open the top of the mint tin, the connector is exposed and facing up and very easy to press into skin.

I disassembled a kodak camera and I saved the components but I couldn't figure out how to connect them again, thanks for the instructable!

Also can I use another transistor, a 2222 for example? Or the high voltage will make it useless?

As long as you dont put capacitors on there its ok.

i am using a d 965 transistor but the shocker is not working although the transistor is fine

Hello! Could some help me figure it out how to make this shocker "less powerful" by discharging, lets say, 50V instead of the 400-450V? How do i do it? Should i simply increase the value of the resistor? Or should i use a different capacitor too? Thank you!

Reduce the amount of turns at the high voltage coil of the capacitor, this is quite hard to do because you'll have to disassemble it completely and unwind and rewind the coils.

The resistor would be an inefficient way to do the same thing.

PD: don't expect a steady DC signal.

Seriously, 9V input is 2700V output :O When I touch this thing, I'll be dead by now!

While it'ss certainly enough to hurt you, voltage alone will not kill you, stun guns can reach hundreds of thousands of volts, but at a very low amperage. When used on someone as they are intended, the risk of permanent damage or death is extreamly low(unless the attacker has a heart condition, but how many assailants with bad hearts can there be?). I am curious about the amperage output from this device, if it's 400-450volts with a .5 amp output, then that is an issue and it needs to be greatly reduced. It only takes .1 mA to stop your heart.

no it takes 10ma to stop a heart.

Ferrite TRANSFORMER WITH FIVE PIN'S From Which Camera You Get Can You Say The Model Number Of CAMERA PLEASE ^_^
I've just made this little thing but it DOESN'T WORK!!!!
I am sure everything works but the taser itself doesn't work!!!  :(
u couldve burn out the parts as well?
Plasmana (author)  rocketlauncher4 years ago
Obviously you have done something wrong...?
I checked and double checked the circuit but it still doesn't work!
try to reverse the connections of the transistor, it happened to me and after i did that it worked just fine...
dlcoates14 years ago
would it be possible to send the blueprints somewhere to get a pcb made for this? if so and where? btw is there a way to make this on a breadboard (protoboard) or to even make this with a 6 pin transformer? because everywhere around here i cant get the free camera shells anymore. and i have like 20 6 pin cameras
easy enough to look up the schematic of a 5 pin vs 6 pin transformer.

Will the big black capacitor work. also why is it " very dangerous" because i got shocked by it and all i got was a buzz sensation (though i am mainly desensitized to low power shocks).

If electricity happens to go through your heart, 0.015A, it can kill you
Plasmana (author)  hyudryu4 years ago
Exactly, touching the capacitor's leads with one finger will hurt. Bad. However, touching the leads in another way which will allow electricity flow through your heart is highly lethal.
Funny you should mention that, a friend of mine had made a little shocker from a camera flash circuit, and because I knew that a person could complete the circuit (albeit painfully), I told my friend to touch the positive lead while i touch the negative lead, and then we would touch our hands together. I guess you could say we experienced a "shocking" reaction.

Just so you know electricity flows from - to +
hyudryu draghi4 years ago
(removed by author or community request)
Actually, electricity does flow from - to + if you want to get technical, but there really is no difference. You could either say that it is electrons moving from - to +, or lack of electrons moving from + to -. Unless you are working with the specifics of how a diode or transistor works, it actually doesn't matter.


PS. By the way, if often bugs me when people refer to the "ground" on a circuit as zero volts, because you can have a huge difference from negative to ground. The terminals of a nine volt battery are actually +4.5 and -4.5, not +9 and -0, as many people believe.
and actually a 9 volt battery is made from 6 AAAA sized batteries
ive always heard i goes from - to + also but i hear more of the opposite now which one to believe?
Actually, I tested it once where i measured the polarity and i touched it from one hand to another (dont ask why) And i felt more of a numbing sensation on the + side and the - wire only had a little jolt. And from the high resistance on my skin, i can say that the voltage decreases once it travels more. And since it weakened a lot on the - side, i think that + goes to -. There dont argue about it anymore. Try it for yourself but use a almost out of juice AA battery so it only feels like a tingle.
Actually it is incorrect. An electrical current is defined by the movement of negatively charged particles called electrons. Try searching on google the inner workings of a battery. You will see that the chemical reaction that occur in the negative lead chamber frees electrons which when given a path will move towards the positively charged lead which loses electrons during the chemical reaction. In this spirit, technical and correct current flow is from - to + BUT!

A lot of people are still using the conventional current flow theory elaborated by
Benjamin Franklin who developed the theory of positive and negative electricity and because he was unable to scientifically verify this theory he assigned the moving particles of electricity the positive charge. This convention became widely accepted and all the following electrical formulas (Ohm's law for example) were based on this theory until Joseph Thomson later isolated the moving particles in an electrical current and realized they were actually moving in the opposite direction of conventional current.

It took a long time before accepting that the real current flow is from - to + and a lot of circuits, circuit symbols and other formulas where based on the conventional current flow which is why we are all having this discussion right now instead of doing something else. In brief, it is all Franky's fault.
