I came here looking for information on etching, for an unrelated
industry. Thus far I've made one (1) board, to make use of the voltage
ref chip that Stefan Trethan directed me to over on Electronics 101, as
well as a number of sheets of brass parts for miniaturists. I use the
cheapest multi-use photoresist system I could cobble up, and I've found
that in some cases I can eliminate the darkroom work (I make litho film
masks for things I'll do more than once) by printing with my old laser
printer on plain copier paper and rubbing vegetable oil into the paper.
With my cheap roll of resist film and oiled paper masks, I haven't even
bothered trying toner transfer.
Aside from that I pick up information that might be useful to me
later, and I too decided to use my powers for Good instead of Evil. =8D
