Homebrew PCBs

Hi Stefan-

I followed your work on this project with interest. I hoped it would
work, but I agree with you completely that it was worth the effort. 

I have heard that there are "drafting pens" which used to be used on
plotters. Has anyone tried one of those with floor polish?
Incidentally there is a PCB resist ink made by Staedtler (see website
below) but it needs a tungsten-carbide pen point to work.

There is a summary (survey?)of a debate and experimentation with
various pens (and some conflicting opinion) at:

http://eeshop.unl.edu/pen.txt

The Lumocolor 313 is commonly mentioned as a good PCB resist pen; I
have used one with mixed results, but it is better than the Radio
Shack resist pen (which is just a Sanford "Sharpie"). Anyway, I wonder
if ink from the Lumocolor would work in an inkjet? According to the
above information Lumocolor do not sell that ink (though someone was
going to try to find it in Germany) so you would have to extract it
from a Lumocolor pen.

In any event, thanks for all your work on this project.
