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.

Can you use any 22nF capacitor, any 22 ohm resistor and what type of transistor should I use, because I willl be ordering the parts.

[qmorrow]

could you coat the transistor with a thermal compound to help it from blowing?

[gclarke2]

could i use a 1000ohm resistor instead of a 220ohm resistor or is that too big of a jump?

[manu08]

won't the wires burnt out from carrying 450v???

[dsherlock]

Just wondering... Would it make sense to build this circuit without the capacitor (and possibly the diode) and then use the output to go into something like a Cockroft-Walton multiplier? I would really like a bit of help with this because I'm quite new to electronics (I've only really soldered small kits before this) and don't know if it would work. Also, can I just make it clear that I'm not going to be using the Voltage Multiplier to make a super-evil-shocker, but to power a Marx Generator I hope to be making soon.
Thanks in advance.

[dsherlock]

And I'm not going to be using the Marx Generator as an evil shocking device either!

AAARRRRGGHHH... >:(
Mine doesn't work....
I have checked everything.

transistor : C3279
Diode : SR2T
resistor : 160 ohms (BROWN-BLUE-BROWN)
capacitor : 22 nf (233)

HEEEELP!

[cobri2206]

Why can I get just 5V?:(
Is it because of my resistants? One is 1kOhm and other is 4.7MOhm. I calculated it here:http://www.csgnetwork.com/resistcolcalc.html
First is brown black red gold, and second is yellow violet green and gold.

[nodoubtman]

the base is on the middle pin, you have soldered the Collector on pin 4 of the transformer, right?

[tesla man]

What is the amperage of the shock?

[patiram2000]

Wat kind of transistor is used?
NPN or PNP???
wat is the name of the transistor???

[dorfster]

Which side Of the transistor is facing the camera? The curved or flat

[dorfster]

Do the resistors have to be this colors. Is there a way so I don't need resistors or only need one.because my cameras have a few other resistors but Im just missing the brown/red/red

[patiram2000]

Hey can anyone help me find all the parts...
I got a disposable camera, but it dont have a transistor.
I have alot of old computer parts so if any1 could give me details on the parts i would find them. Please Help Me!!!

[dlcoates1]

Here is a quick question. I saw you attached that little yellow capacitor to the circut. Is it really necessary? There is another video of someone making the same one as you but he doesn't add the capacitor at all and it still does the same thing without the capacitor. Can you please explain the difference?

[Guardians38]

I wrecked the Transformer when i desoldered it and I dont think that I can desolder it without ruining it ... is there anywhere that i can just buy one? ive looked at radioshack

[thehackster]

to desolder it i used a propane torch it worked much better than a soldering iron

[nathanielg]

search on google inverter transformer and electronics goldmine should have one for like $3 or less

[techno guy]

You don't have to desolder anything, just cut off the huge capacitor (not the little one) and touch the contacts where the capacitor used to be.

[nprikkel]

Anyone have a downloadable eagle file for this!? it would be super helpful. I can't seem to find any of the pecies in eagle. and im expirenced in eagle... odd right? so help? please?

[draghi]

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).

[hyudryu]

If electricity happens to go through your heart, 0.015A, it can kill you

[Plasmana]

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.

[bigstiffy]

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.

[hyudryu]

Well if you touched the - lead, you will feel a LOT less of a shock because the + lead is where the electricity starts. going through your friend, it loses a lot of power already so once it gets to you, its weakened... LMAO

[draghi]

Just so you know electricity flows from - to +

[hyudryu]

Not really 0_o Wuts wrong with you. - is ground its 0 volts and + is high its > 0 volts

[maxwelljets]

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.

[Jimmy Proton]

ive always heard i goes from - to + also but i hear more of the opposite now which one to believe?

[dumle29]

well as i see it, electricity flows both ways. It depends on how you look at it.

if you define + as the side with an excess ammount of electrons, then it flows from + to -.

if you however define + as the side that is positively charged, it flows from - to +

it depends on you defination of positive and negative.

personally i prefer the + is a positve ammount of electrons, therefor i prefer the: "electricity flows from + to -" thing. just makes it easier to work with diodes i think :)

[hyudryu]

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.

[John.Henry.]

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.

[Jimmy Proton]

why no just use diodes lol

[hyudryu]

Lol that would work too but w/e i tried it with a used battery so it didnt hurt and the current is too small to damage my heart because theres no capacitor -__-

[Jimmy Proton]

on a diode does the electricity flow like this ---> ->| -----> or like this <---- ->| <------ (->| is the diode)

[draghi]

OK Gnd is not - Because this is how i remember it: - is like subtracting from a Battery's power. + is like adding to a battery's power. Gnd is is any grounded object like a water pipe eg. therefore - is out + is in gnd is get rid of.

[draghi]

thanks!

[hyudryu]

The easiest way is to desolder the capacitor, solder 2 wires in place of it, connect that out, put the circuit back in, close the camera. There Its safe and it HURTS LIKE HELL. I fried an ant... I was bored so ya

[rocketlauncher]

I've killed a 1.5" long cockroach that way!
