Homebrew PCBs

SG,

If a hobby magazine provides a PCB layout, then it should be fine to make a
single board for home use. It would not be fair to copy the magazine and
give it out to your friend. Similarly, it would not be fair to make lots of
boards and sell or give them out to friends.

There is something called the "fair use doctrine" which governs such things:

http://en.wikipedia.org/wiki/Fair_use

Now, there is also something called Copyleft, which I routinely use. You are
free to copy and even sell anything I produce but I don't want you to change
it including but not limited to removing my name.

Rick,
Thanks for the very thought provoking mail.
Now, visualise this. I buy one hobby magazine. They provide a PCB design
with the mag which I want to get fabricated at home. I print the pcb from
the optical media provided with the mag on a tracing paper for making a
film.
Is there anything inappropriate? Kindly enlighten me.
