It has been a while, since my last post here, but I’ve been active at my second website, located at http://helikoid.si. However, in future I will publish at both sites, but possibly the site at helikoid.si will contain (randomized:)) articles about interesting-hobby-research/reviews/tests and some of my notes which I’ll share with broader public (perhaps someone would find them valuable, but at least they will be for my reference).
