Instructables

Step 4: The beginning of the hardest part ever...

Okay, here we go, build the shocker, the hardest part ever...

Read step by step through this instructable until you get to the end...

Okay, get all of the wanted components, fire up the soldering iron, turn on your work lamp, get a magnifying glass, and HERE WE GO!!!

Also I made a schematic and a design that should help you how to build a shocker...


Step 0: Start with a five pin transformer.


UPDATE - 9, October, 2008
I have improved the schematics, I hope it is easier for you to read.

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.

could anyone provide a link or tell me what kind of transformer i should buy? i had a look on ebay but all i found was this :http://www.ebay.com.au/itm/13V-Output-220V-Input-4W-5-Pins-Electronic-Component-EI-Power-Transformer-/330820953105?pt=AU_B_I_Electrical_Test_Equipment&hash=item4d06772411&_uhb=1#ht_2183wt_1141
could this work without the 220 ohm resistor because i have tried it many times but failed just as often. i think it may be more successful without this resistor as it would separate the primary and secondary coils. what you have shown appears to be indentical to the circuit already in the camera which does work so why won't mine. please try and explain if i am going wrong anywhere. thanks

Man, i have one of a new printer whit 9pin and other things, can i make something whit those, can you help me?

I don't understand how this circuit works. I have seen other shocker circuits recomposed from old disposable flash cameras that are connected in entirely different ways. In your circuit, it looks like flow initially travels into the secondary coil through the 220 Ohm resistor at the center tap, and then into the top through the capacitor and diode. Then, it flows to the base of the transistor which allows current to flow through the primary coil. At this point I'm confused. How does this step up the voltage? Also, how do you have an output of 450V when the diode prevents electricity from travelling in that direction and it sure as hell doesn't travel through that 220 resistor.

Couldn't you do the same thing but bigger if you just cut off the huge capacitor from the original circuit board and touch the contacts where the capacitor used to be?

Hello Plasmana! Can you tell me the impedance between pin4 and pin5, and pin5 and pin3? Thank you. Good tutorial by the way! Keep it up!
Plasmana (author)  sousa6 years ago
Hmm, I don't know the impedance of this transformer because I don't have a impedance meter, but I can tell you the resistance. Pin 3 and 5: Between 270Ω to 330Ω Pin 4 and 5: Between 271Ω to 331Ω
that cant be right, because i have just tested all the transformers i have harvested,
and they all give readings like this

1-2 = 0.7ohm
2-3 no reading
3-4 no reading
4-5= 0.4 ohmand these are readings i get from transtformers that i cut out, not desolder.

wold somthing blow if i used a 9v

plasmana can you tell me what type of diode you use and if I can use others
Plasmana (author)  MiitheWii5 years ago
I think it was F1, I am not too sure... Use an 1N4007 diode instead.
what a coincidence, i cant find any in the cmeras but just bought about 500 for another project (it only reqired 1 but the store only sold in bulk), also, and im asking you plasmana, will a 6 pin transformer work, because i cant find a single camera that uses 5 pin transformers, only 3 pins and 6 pins

I opened up a camera, but the transformer has 6 pins, how should i connect it? one of the middle pins isn't connected to anything as far as i can see, but it could be connected to something inside the transformer... anyone any ideas?
joinaqd5 years ago
Plasmana if you can, please open one of the transformers and please write down the primary and secondary windings and how many turns they have.I know from Wikipedia that the transformer is a center-tap transformer(meaning it has a wire connected in the middle of the windings but i dont know on which one,primary or secondary?). If you can, please open one up and examine it and send me your observations so i can try to make it using a bigger ferrite core and more windings for better and higher voltage.(Im currently out of cameras, so im trying to use a bigger ferrite transformer core, like the one from ThermoElectric's Inverter). Thanks

i have a 4 pin transformer and a 7 pin witch would be better/stronger to use

i have a 4 pin transformer that i got from a kodak camera. will that work or does it haave to be 5 pin?
geeklord5 years ago
The second circuit diagram helps, because i can identify the different pins.
Plasmana (author)  geeklord5 years ago
That is good.
geeklord5 years ago
Yea, i think my Kodak transformer has the secondary coils between pins 1&2.
scuse me, primary coil between pins one and two.
girrrrrrr26 years ago
mine has 6 pins... 4 on the top and 2 on the bottom... help please? all that i can find have this config.
Plasmana (author)  girrrrrrr26 years ago
Unfortunately, the 6 pin transformer won't work, you need to find a 5 pin transformer.
ok i looked at it somemore and it seems to have a pin that is not attached to anything at all... um what i am asking is tat if i rip it out do you think it would work, because if i do it looks alot like yours, without the extra bit of plastic...
