I think you misunderstand the obsessive, blissful, motivations of a nerd. :)
I was like this when I was younger, where a goal like this would entirely consume me, regardless of practicality, and more of a "see if I can". Some of the best days of my life, where I was most alive, were those times of complete, detrimental, obsession. As I grew older, and patterned by employment, it slowly faded, and sometimes I miss it so much.
(funny enough, I was once nerds sniped about a grids of resistors, to understand PCB trace resistance better, for high currents, because an EE said my intuition was wrong. I made a paint program where you could paint/paste an image, with red being + voltage sources, blue being negative, and greyscale being resistance, and it would show you the current flow through whatever you drew. I was able to prove that my intuition was actually correct!).

Kind of the point of a board called Hacker News. Doing it yourself while someone else holds your beer is on a totally different level compared to someone buying something off the shelf at a fraction of the cost.
