> 3 Were do you get your presensitised pcb's from? In NZ you can probably get this from RS Components. Probably pretty expensive, but if doing it just for hobbyist use where you only need a bit now and then this may well be a small quantity way to do it. Don't get too much as I believe the coating has a shelf life that is not too long (maybe a year or so). Check this out before buying a great bundle. Otherwise Russell's notes should help you. -- http://www.piclist.com hint: The list server can filter out subtopics (like ads or off topics) for you. See http://www.piclist.com/#topics
