Some people like to get super nerdy with them now. If I were in better shape physically, I'd probably etch my own out of some PCB copper clad and mix up some tinning solution.
Ooooooh.........yeah, I read it as you saying it would be hard to do with no upper body strength, or if you were really fat.
By "better shape", you mean you specifically as an individual. Thats what threw me off. I know nothing of the process, and thought you were saying I couldn't do it, being fat.
