James Newton has collected information from this and other Yahoogroups about making PCBs. Massmind
A list has been set up just for discussion about converting inkjet printers to print etch resist directly onto PCBs. Hardware, software, inks, baking, etc. are on topic there. Go to Inkjet_PCB_Construction
Questions on general electronics should go to the Electronics_101 list.
