The traces

Vaxman -- thank you for the idea; we might revisit it when there's more time post-VCF. For now I've gone to A.C. Moore and purchased gold tape. It's actually a pretty good watch for bare wire color and has shiny (ooooh shiny) lines down the middle.

Haste makes waste. We've a nice, new, beautiful display area. It'd be a shame to half-ass it with quick-n-dirty paint job. What does it matter if it takes 2 hours or two months to complete. In the long run, a well done "mural" will add to the whole display's appeal, IMNSHO that is.

Figure out where the traces need to be, then spray a copper paint in on the wall in the approximate location (no sense wasting paint... I would suggest Krylon metallic copper) and then, using *good* painter tape -- 3M Painter tape for delicate surfaces #2080 -- lay out traces over the copper. Press down well for good adhesion. Paint over the tape with the green paint. Pull the tape BEFORE the green is completely dry to avoid egde chipping. #2080 is what I use on all of my rocket paint jobs. It's never failed me. Do some test runs before you tackle the big job. ;) Corner round cutter and a hole punch can make nice and even solder pads too. ;) The 3M tape comes in various widths too.

I forgot to mention/suggest that the Krylon metallic that's exposed be lightly sanded to allow the green paint to better adhere.

Tony, Chris F., and I will be working at the new museum Saturday from about 10am until whenever. We're going to paint one of the short walls "circuit board green" for the modern history exhibit, set up more microcomputers, and get going on a few other projects. I wish we could do this tomorrow! I'm having tremendous fun watching the new space come alive. Alas, three more days of boring real work until the weekend. :(
