PCB Russian pirate metal detector in an exclusive and new way

Printing the electronic board of the Russian pirate metal detector in an exclusive and new way

1- Print the circle on white paper

2- We will use transparent paper that is used in cooking a lot, called butter paper, to draw on it the circle that we knew in the first step, and then print it on the butter paper with a black felt-tip pen or any dark-lined marker that does not erase easily.

3 - We buy a copper plate from stores that sell electronic parts. I bought a good-sized plate from a store at a price of about $7, then we cut it according to the size you want for your circuit.

4- Then we iron the parchment paper with your clothes iron on the copper plate for a few minutes.

5- Then we remove the transparent paper, which is the butter paper on which the circle was printed in Step 2, from the copper plate. There is no need to use water here, as it will not stick to the plate.

6- We prepare 10 grams of table salt and 20 grams of lemon salt, and add them to a bowl containing 50 ml of drinking water, and stir well until completely mixed.

7 - We prepare hydrogen for hair, and it is available in all pharmacies in the world. If you do not find hair oxygen, instead of it, bring it from the pharmacy, which is oxygen for hair, and we add approximately 12 ml of it to the same container in which we mixed salt with water and stir them, but my brothers, beware, be careful, because these materials are dangerous And be careful not to touch it with eyes or the body or breathe comfort when working on it.

8 - Now the solution for dissolving the excess copper that is on the plate is ready, and we only have to put the plate that we prepared in the previous steps in it for a period of not less than half an hour and not more than an hour, and our plate will be ready, and what you have to do now is to clean the plate from the black color or the color that you used By printing, this color can be removed through a nail polish remover solution, which is available in any market, and then the plate begins to be pierced and then the electronic parts are attached.
