Homebrew PCBs

I did something similar for the local amateur radio club, but as a demo.

I took along a pre-prepared transparency, a pre-cut piece of resist-coated copper laminate, my UV exposure unit, developer and etchant. I exposed the laminate, developed the image, and then etched the board. A lot of members attended and were suitably impressed. I haven't hear of any of them trying it for themselves, though.
