There are only five weeks until VCF East. Realistically, we can only be there one day per week to work on this stuff.
In the long run, a well done "mural" will add to the whole display's appeal
I agree. How much time do you have to help us?
How large an area do you wish to cover???

The wall is approx. 15 ft. wide x 10 ft. tall. If the specific color you use is too much $$ then I suppose any generic "gold" would do the trick. Again, the point is to evoke, not necessary to exactly replicate. I have a list of about 30 items that are all now in your phone. So that's how many traces we would need to make from the edges toward the center.
Thinking out loud some more: gold traces are on the BACK of circuit boards. On the front all you usually see is a brighter/lighter shade of green. Am I nuts?

Skip the painting of the traces all together. Just paint the wall one solid color, then afterwards use self adhesive LED strips so the "traces" are illuminated.

Never heard of that. Looked them up just now. That's too Vegas for us. :)

Gold traces (if any) can be on either side of the board, or (just as often) on both sides. Card-edge connectors are the "iconic" place to find gold plating...if you throw in some of that it'll be recognizable. The green comes from two places...The top layer of glass/epoxy and the solder mask. They are sometimes different shades of green; that's what you're noticing there. There are actually many different colors of both, though green has historically been the most common. Anybody ever use OSH Park for PCB proto runs? They're purple. Very regal. ;) -Dave -- Dave McGuire, AK4HZ New Kensington, PA

You go Dave! I got a little lazy with my description but you filled in the details. :-)

Not at all, very cool. I appreciate your knowledge, experience, and thoroughness. I know a little bit about a lot of things, I just wish I knew a LOT about something. :-)

Ahh, we are opposites there. :) I know jack-point-squat about anything outside the science/engineering areas. :) -Dave -- Dave McGuire, AK4HZ New Kensington, PA

Good point. Not sure if we have a place to do that. Cray + STK block most of the bottom of the wall and there will be signs across the top.
