I built a "headphone", from a kit. Basically a coil and a iron thin sheet.

It is actually simple, but using gates, not transistors. Well, 
transistors is one step further, each group form a gate. And a group of 
gates form functions, like registers. It is overwhelming from scratch, 
but if someone explains a function at a time, it becomes 
"understandable". At least an old 8 bit CPU, like the 8085 or 6502. A 
modern one is more steps in complexity.

Nobody can explain or understand a modern CPU from scratch.

And I could not write the explanation of a simple CPU, either. I have 
forgotten many things.
