@foone Oh, yes I was doing that when I was a teenager with my dad in the 80s. The difficult part once etched was drilling the holes for the components. That was very tedious. You could also purchase "décalcomanies" (sorry can't find an English word) of pads and tracks that you could transfer to the copper layer.
It's now so much easier to produce Gerber files and have the pcb manufactured II :)
