Ask YC: Hobbies as a Source of Frustration?

Now that I am an engineer, I understand the amount of effort required to complete a project. The downside of this is that the natural curiosity that I had as a kid toward playing with electronics/software projects is suffering. To do anything interesting to me requires more contiguous time than I have (and for electronics, more sophisticated equipment than I own).

I secretly believe I'm just trying to recapture the fun I had playing with lego or my Atari 130 XE as a kid; projects were self-contained and could be done in a single sitting.

Does this happen to any of you? How do you deal with it?
