Build a World's Smallest Electronic Shocker!

FeaturedContest Winner
This amazing little shocker is very tiny and can be hidden almost anywhere and give someone a surprise shock! It can operated by almost any 1.5v batteries!

So, on this instructable, I will show you how to make shockers that is smaller than a penny!

However, the biggest disadvantage of this shocker is, it is very hard to build, but it may be easy for experienced soldering iron user (like me) to build the shocker...

Please note that I am only 15 years old and I am not very good at grammar so if you find some parts of the instructable confusing, please let me know and I will try fix it.
And excuse me for some of those blurry and hazy picture. I cannot make them better...

New and improved version!

Build a World's Smallest Electronic Shocker! version 2.5

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

Step 1: Get the things!!

Picture of Get the things!!
Hardly anything is needed for this project but the tools...
  • "Boots" or "Polaroid" type disposable flash camera (You can use a Kodak camera, but they are harder to work with).
  • Some wires (I got mine from broken electronic devices).
  • Solder.

And the tools...
  • Soldering iron with a micro-tip.
  • Desolder pump (it makes everything so much easier, but you could probably get away with out one).
  • Flat-head screwdriver.
  • Wire strippers.
  • Wire cutters.
  • Pliers.
  • Tweezers or micro pliers (or your hand, but you are more than likely to get a solder burn).

Also, if you don't know how to solder, read this great instructable!

what part number is the transistor from the camera? is it NPN or PNP?

mine only gives 37 v


very good instructable i figured out the fault in mine and its working now

can i use a transformer from a mobile charger. please reply
dudes spirit x2 months ago

you could, however a mobile phone charger usually will only multiply the voltage by 10-25 times while the transformer he is using does 300 times.

can i use 47nf capacitor istead of 22nf

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!

Hi Plasmania - I think there may be an error in your circuit diagram that may explain some of the complaints. Every component pinout I can find shows Transistor 'Base' to be the middle wire. (E-B-C, rather than E-C-B). If that is the case (and assuming the photos are correct) Transistor Base is connected to XFMR pin 1, and Collector is connected to XFMR pin 4 That also keeps the Base on the 1.5 V side of the circuit. I tried to upload a revised schematic, but that doesn't seem to be working...

Could make a good mouse zapper. If it's 250 volts @ 1.5 volts What would a 9 volt battery do? Do you know the approx current? Is the cap a discharging cap? The discharging cap could be reduced to prevent a burning ark? For use in Dogs (as in lets not mark our territory there anymore boys)?

Hello, I'm new to electronics and I was taking a look at your circuit trying to figure out how it works. If you don't mind I would like to know what is the purpose of the 220 ohm resistor. Thank you.

I recently made 8 of these and put them in parallel to charge a capacitor bank. Now, when using one to charge a capacitor I require an RC Circuit. But, when I made the 8 in parallel no resistor was need to charge a capacitor. I was just hoping you could clear up how I could have built up the resistance to not require a resistor to charge.

Mine doesn't work, it gives 1.5V output. I'm using a 500 ohms resistor since the one that came in the camera was 1k

can you connect this to wire loop game ?? where are the line 1 line 2 terminals? please tell mee :)
How fast does this shocker run at?
i have a small transformer with 5 pins and red tape around it, its about as big as my thumb, would i be able to use this?
thats all the info i have, no markings on it

can i build it with 6pins transformator? becuose i cant find one with 5pins..:(

would the transistor be a pnp or a npn?
Relate the pins of the symbol this the type of transistor:
1. The arrowed pin [Emitter] is always points at the "N" pin.
2. The pin that goes to the center of the bar is always the Base and is always opposite of what the other two are.
3. The non-arrowed pin is always the collector.

So the transistor in the schematic above has the arrow pointing out making the outside letter = N, so it has to be a NPN.
If the arrow pointed at the Base, then the Base would be N, and the ouside pins P,
thus it's a PNP.
Does that help?

what wattage is the resistor? 1/4, 1/8, 3, 5? i want to but the pieces but i dont know which one
going off of size alone i'd say 1/8. either 1/8 or 1/4 should work though, the only difference i know of between the two is size and heat dispersion.*
(assuming they're both 220ohm

What are the farad ratings on that capacitor? 1000nF? Probably 2200nF?
I've just started this project but i had found more than one transistor which i should use ?? and you wrote to be careful while desoldering it . is it possible to give the code of transistor so i can buy ?

i would be thankful if you be in touch with me
Is there a way that i can tell appart different types of transistors?
I dont know where the base, the emitter and the collector are.

Thanks in advance
It depends on if it's a PNP or a NPN transistor. Flat side up looking at the pins a NPN is E. B. C. A PNP is C. B. E. does that help?

Have you tried using google?
i managed to build a simple shocker but was unable to make one this small. i rewired the camera charging circuit so that the input went to a battery holder and there were electrodes where the capacitor was. i have tried to follow this method of "deadbugging" a number of times but could not get the thing to work. am i just crap at soldering? by the way the capacitor in this circuit isn't needed the system works just as well without it, or so i have found with my somewhat bulkier version.
320 volts at almost 0 miliamps is just painful. Not dangerous. I have touched a Jacobs ladder and am still standing. That is alot more powerful than any from of disposable camera. Just saying.

can anyone tell me the specification of transformer used in this shocker....?
Have you tried just using the stuff from a cheap disposable camera like in the ible? the cameras need to create at least 330 volts to charge the flash, so every camera should have the components the make the high voltage.
Whoa, after seeing the voltage with 4.5v input I think it would actually be feasible to power a photomultiplier tube as well as many other things with this little thing! Did you use this as your design for the 450v inverter on your Marx generator?
godwhite2 years ago
It took me a while to figure out, but it seems your schematic diagram is wrong. Based on the picture of the transistor you've shown, you've hooked them up this way.

(crappy picture I made with paint)

This makes more sense because you're giving the base of the transistor a lot of current. When you do this, you're putting it in saturation, and it allows large currents to pass from the collector to the emitter without burning up the transistor.
