[sdiy] Two more questions

[charlie lamm]

As far as the 2nd question, I think for single-sided PCB creation,
assuming you don't need to make a whole bunch of PCB (more than say 10),
press-n-peel really works; I have gotten excellent results with it.

There is a lot of info on web about how to use it, but I found these links
to be esp. good:

BTW: The hardest part, I have found, is cutting down the board before or
after you get the traces pressed and peeled, short of buying a "PCB
breaking machine" (don't know the right term) which I cannot afford.  For
this, I have scored the board top and bottom with a box cutter and broken
it in a vice.  Anything involving sawing or cutting PCB's produces
horrible, choking, toxic fumes and dust, so I'd avoid it if possible.

I've also seen rub-on decals which I'm guessing are used instead of a marker.
