    Joe, I havent figured it out to the dime yet, but since you brought it up, lets take a look at the numbers.

    I got 45 boards at 3" X 4" for $35, thats about $.80 for one board.
    The Hydrogen Peroxide is $1.50 for a BIG bottle, I only use a "splash" to etch.
    I forget how much the Hydrochloric Acid is, I think it was $6 for a bottle.
    The magazine I print on for toner transfer, was free.
    The cost of the toner should be calculated, Id guess $.10 a print.
    The Acetone is used to remove the toner after it is etched.
    I already bought the drill bits. I wont calculate that.
    The software (Pad2Pad) was free.
    The laminator was $80 but Ill chalk that up to start up cost.

    So that should be:

    Board: $.80
    Hydrogen Peroxide: $.10
    Muriatic Acid: $.25
    Toner: $.10
    Acetone: $.10

    Total: $1.35 per board

    From print to board ready to solder, about 10-12 minutes. That includes drilling. And its fun.

    Wow Brian, slow night at the Hosendia? HA HA! Thanks for the interest.

    As soon as I really have some free time, I need to put together a full and detailed posting on the full process with full detail.

    Thanks for looking-

    Hello Andrew

    Do you dilute the Muriatic acid and if so what is the ratio?

    What concentration Hydrogen Peroxide do you use?

    Please dont take this wrong, but I want to point out, I spent a lot of time and energy in this thread. All the information you need is in the 13 pages of this, plus some information you dont need! HA HA!

    To just give you the information would be too easy, so I will respectfully ask you to go back and read up, plus some questions that may arise will also be answered as you read.

    Its a good read, and I promise its not a waste of time! I also promise, if you follow my method, you too can make your own 99% perfect PCBs!!

    Thanks for posting & 73s-
