TATTOO MACHINE

My tattoo machine! a friend of mine tried it and he now has a beautiful tattoo on his foot! ahhaha

DISCLAIMER - BE CAREFUL!!! NOT A TOY!!!! NOT FOR CHILDREN!!!

I WILL NOT respond of any damage or injuries on people / animals / objects!!! your risk! :

The story:

I designed it for a friend of mine, who needed it. 

We went out to drink a beer in a bar, and we draw a sketch. 

Later I designed it on Fusion 360, then I printed it and tested it on a BANANA! XD The result was good (see the photo)

When the machine was ready, my friend tattoed his foot and it worked! 

A simple circuit is needed to control the speed of the motor. I designed a simple NE555 PWM controller. You can see the schematic on the photo. Maybe you can design a better circuit, you can use the box to fit your design in.

I have bought sterile tattoo needles from amazon:  https://amzn.eu/d/7zfmDql

(8mm plastic diameter) ( I can't find the original link but I think they are compatibile)

The motor is a generic RC DC electric motor. You can find it everywhere, like this one: https://amzn.eu/d/ge5mQG1

You will need some little screws.

You have to be careful:

• the cartidge of the needle must be regulated and then fixed by the frontal screw
• you need a elastic to hold the needle on the rotor in right position.
• the pivot  can be replaced by a screw
• the motor has to be powered by low voltage (like 5V to not damage it)
• be careful about the circuit you make, you can be electro shocked!! maybe it is better to buy one if you are not sure.
