A large faction of engineers, especially software-type engineers, have these types of hobbies.

I’m sitting here right beside the heirloom quality (compared to most furniture) coffee table I made in my garage with my nearly complete wood shop.

I make stuff in two ways in my day job. I design something and someone else makes it, or it’s just some idea as software.

Engineers are a type. We’re just wired differently from most other people.
