Not really what you thought, maybe, but true.
I've often thought about scratching a whole circuit onto copper covered in sharpie as I use the scratch method to cut the lines between IC pins, electro caps, etc. just the other day I decided I needed another 386 on a board but it was all inked up and so I drew on top of the sharpie ink with a pencil and lo and behold I could see the lines so I put in the circuit for the 386 by scratching away the lines between the bits I wanted isolated.
This led me to do this, which is a Bass paralooper, and it was completely sharpied then marked with pencil then the un-tracks scratched away.

So heres yet another way of doing PCB's. Thinlayer of wax to start might be better than sharpie though.
Looks pretty...
Does it work?
Huh, interesting way to do things. I would think that you would need some good strong & steady hands to do that well.
That looks great ! Too bad using clear enclosures is a ususly a bad idea because it would be nice to show off something like that.
I bet you could use a Dremel with an engraving bit! I use a tiny one to drill PCB holes, but never thought of using it for anything else.
Hmm... gears are turning....
Looks like my neighborhood.

It's much easier to see it before its etched, oh and my scanner needs a clean, and I've always had problems with sharpies not covering as well as they might, ends of strokes etc, so I'm going to look at alcohol based screen printing inks so I can just cover the whole board then scratch away what I need and because one isn't eating away so much copper then less etchant will be used even if the time stays the same.
I'll swap them plus some knobs for some electret capsules and a bunch of PT2399's.

I thought of this after the fact so the thread isn't an add.
Looks like the back of my head....
Anyone try an engraving pen ?
A hand held electric 'jackhammer' point tip ?
Even if it doesn't remove all the traces, perhaps it'd be a way to start so the rest of the scraping would be easier to keep on the lines...
