PCB plotting

Festival season equals Tinker opportunities!
I had been inspired by the wiki post at
http://reprap.org/wiki/Plotting to construct my own pen plotter in
order to enable my Makerbot to etch PCBs. That should be funny for
small prototype boards.
I started with designing the pen holder, which can be seen here:
http://www.thingiverse.com/thing:5288 and after some fiddling around I
am on the right track to create a profile for skeinforge which directs
the plotter along.

Simultaneously I designed a small servo driven shaker in which I can
put the PCBs for etching. That is not entirely finished yet. However,
if you plan to make things that move, how about reading the book:
Making things that move
(http://www.amazon.com/Making-Mechanisms-Inventors-Hobbyists-Artists/dp/007174...).
It is a very funny, entertaining and educating book. Well done, Dustyn
Robot!
