As someone who has recently gotten super interested in soldering and other DIY matters, I would too love to have a central hub for news and relevant stuff in this subject… :)

Sounds like a project in the making.

The problem is that places like HN perverted the term "Hacker" by making it a synonym of developer/coder, which in previous meanings covered what you call "DIY'ers".

Everybody around here calls himself a hacker, when in the past it was more an achievement than just a job you can choose.

True story, haha.

I also remember used to be that "Hacker" in the programming context was looked down upon. Meaning, you had no idea what you were doing (you were a "hack") or you were up to no good (black hat).

Some fraction of HN users are professionals in the primary fields it covers. By definition DIY'ers are not professionals.
