I've using perforated circuit boards along with cable for some months, since I started with practical electronics. Now I'm thinking of using copper PCBs, the ones you draw the lines on it, and then put it in some acid liquid (not the photo-sensitive boards).
what things do I need, like, for example, to make the holes?
Any permanent pen would do the job?
Is there any "not-expensive" acid solution?
As I never used this before, Any clue or advice?
Thanks a lot
