I need to bild a tattoo power supply. I think I got all the parts but I dont know were to start ?

I have a transformer that's 12.6v , the phone jack's, the bridge rectifier, fuse holder, and electronic capacitor.

Ok, you will need a variable power supply as machines will differ in voltage to achieve the "sweet spot". What you will need:

24V 2A transformer
5k potentiometer
AC fuse holder w/fuse
4 x 1n004 diodes (bridge rectifier)
220 ohm resistor
470uF cap
10uF cap
AC female plug
Adj voltage regulator (LM317)
heat sink for reg.
Pref board
I always use a led as well a nice knob for the pot as well as a volt panel meter although if you are a experienced tattoo artist you can tell by the sound of your machine vs the actual V you are supplying. If you have all this and are still interested I can photoshop a schematic real quick and post it.


Hi there. Could you send me a schematic for the power supply? YS iq0100

bechnielsen@stofanet.dk Thanx

Anyone still has shematic for power supply email it to me as well thank you cartel100x@hotmail.com

Hey, there's a question almost just like this higher up the list.  Except that other guy doesn't know or have what he needs.  Why don't you two get together and pool your resources/brain power?

Welcome to instructables;

Assuming you already have the tattoo gun, I understand it operates on DC current - working as a mechanical oscilator on a solenoid...

So; you have the Line electric>> fuse>>transformer>>bridge rectifier>>Capacitor>>foot switch>>output to gun.

This is a simple transformer rectifier.
The fuse should go on the HOT AC line - demarked generally with a black wire (not white or green) and it will be the smaller blade on a north american electrical plug. 
  The bridge rectifier will have markings with little ~ signs denoting the AC sides, generally on opposite corners.  It doesn't matter which AC wire goes to each of these.
The power coming off the bridge will be POLARIZED and have a - and + marking.  This is important.  The capacitor will have a line on one of the sides or nearer one pin.  This is the NEGATIVE side.  Hook the capacitor in parallel between the + and - with the correct polarity (- to -, + to +). 
Now you have nice pretty rectified and smoothed dc output. 
Hook it to a switch, and to your output.
