Homebrew PCBs

Hi

did today try the iron on again.
Damn thing won't work.
used different Papers (magazine).
Problems: the lines get sqeezed, turn out broader than they should be, but 
very irregular.
also sometimes there are holes....
a straight line looks awful... lika a very bad scan or so.
may buy photo paper monday...


BUT - i read of something new:


http://www.solarbotics.net/library/techniques/buildpcb_trnsfr.html#blender_pen

Resist pattern applied via "blender pen"
This method comes courtesy of Jesse Willis: What I did was swing by my 
local art store and pick up an Eberhard Faber Design Art Marker, Broad Nib 
311 Colorless Blender (only about $2 US). With this, you simply photocopy 
the circuit you wish, and then lay the photocopy face down on the PCB. Run 
the marker over the back of the photocopy, and the image transfers to the 
copper.

also read this message at the bottom:

does anyone has any idea what is going on there?
I assume this is some kind of solvent pen, but which, how, why, where to 
get?

stefan
