Yeah, there's definitely a wide spectrum. I just kind of lump them in as makers. Most of the people I've met at my local makerspace fit this bill - they're just tinkering with something or taking up a hobby. But as I mentioned, most of these people I've met are/were engineers professionally. I think it's just that on their personal projects they were more relaxed about "process" than they would be at work.

When I was in doing my Engineering degree in college, one of my professors once tried to make a spectrum of technical ability. One the low end he put "tinkerers" and on the high end he put "engineers." I think that's where a lot of my perceptions of technical ability are coming from. Like I said, it's just my opinion
