It's more about the journey than the destination on most of my side projects. Yes, the end product is meant to be useable by me (hence me expending the effort). However, I tend to learn new build techniques or it's a chance to hone a skill. Do all of my solder joints look the same/consistent (hopefully good)? Did I really need to make a biscuit join? Could I have make a cleaner cut into this plastic using a hot knife vs a spinning blade?

You know non-software nerdy hacker stuff.
