Why a DIY section ?

For a lot of what I know and can do today in audio, I’m obliged to numerous DIY communities all over the internet. Sites like diyaudio, troelsgravesen, passdiy, linkwitz are the reason, why I got interested in audio hobby in the first place, so this is my way of giving something back.  Here you will find all kind of projects  and articles (not necessary audio related) that didn’t made to the audio gear sections.
