  2. Making PCBs with magazine's paper

    No I mean electrolysis

    Here it is how it works

    You get an old car battery you take the electrolyte then you mix 1 liter of the electrolyte with 300ml of distiled water (30%).Then you put the liquid in a tub you put the plus electrode to the copper which has to be eaten away and you use for a minus electrode a piece of I`m not really sure which is the best metal I`ve tried with lead but I think that the electrode should be made of Zinc I haven`t got zinc very much so I used Lead.After that you should have a really Powerful power supply because at 24Volts I measured 23.7 Amps and the power transistors of my Bench Top PSU got really hot I think I could have frien an egg on the radiator but after 3 minutes the copper was almost gone. Then you put the board in regular acid or FeCl3 for final eating away and that`s it.There other ways for making a board.For me I etch my boards with FeCl3 or Nitrogen Acid.

    I prefer the ordinary way.

  3. Making PCBs with magazine's paper

    Haha I`ve been using this method for making PCB`s for year and more.There are a little secrets for making these PCB`s.


    First for me I`ve tried so many types of paper but I think that the best one is Ink Tec`s Premium photo paper.

    The most important process is the ironing most of people say that the PCB should be ironed for 2 or 3 minutes at full temp. That`s not true because in most ot the photo papers there is around 40% of Polypropylen and Polyethilen when you fry the paper with such temperatures the plastic in the paper stick on the PCB and happens nothing the best temp for is 140 degrees.

    Putting the board in water is a mistake because you will remove the paper harder than if you try removing it gentle when it`s dry.

    If there are broken tracks you can fix them by redrawing them with a permanent ink or straight a permanent marker I use Schneider S303.
    After that you can put it in the FeCl3 and etch it.

    I know other methods for really fast etching for about 1.5~3 minute etching using electrolysis but I`m going to write a topic about that method Has someone ever experienced with that method? ???

    Hope I`ve helped you ::)

  9. First Project

    Actually my first project was a Time Delay Relay Why don`t you try this? The first delay relay I made had only four transistors after that I tryed the 555 timer monostable,astable mode after that CMOS circuits, TTL and so on and so on.Just you`ve got to be patient.Don`t worry if you burn a chip or diode I`ve done this thousands of times.

  21. Adams Motor Project

    in Inventive/New Ideas

    Well I think that this is a little amazing and maybe all this stuff seems for me to be untrue because the motor can not recharge the source of power by itself there is always loss of power.Tell me a little more about it I saw the links that you gave me but I had a little work to do so I haven`t read them carefuly. ::)
