Hi Nial
I found this 'direct toner' method from 'platinen' forum at german site
http://www.mikrokontroller.net
there was reference to a real great manual (unfortnatly in german)
http://thomaspfeifer.net/
go 'trickkiste' thee is picture and long story with many pictures
some english links can be found
google PCB DIY toner
http://www.michaeladams.org/?Electronics:PCBs
have fun!
this was my first testing with that method and really worked
I spent at www.conrad.de
2 EUR for the fine aetz kristall (for acid making)
3 EUR for 20 bx 30 cm PCB
2 for plastik thing where to put the acid in
thats it. I have almost all the PCB and acid overleft so can make more
boards within a few hours from idea to ready board
Antti
PS I will post the picture of my first board to my website as soon as get
shot
.
