Topic for a new blog

Hey ppl I am Ashmeet Singh. I am the owner of NewtrojansBlog these days I am thinking of opening a new blog. But I am confused on what topic should it be !!!!!!!. As I have a techno blog earlier then it is no point making a new one and cutting your own traffic. So please suggest me some topic except Latest gadgets or Tech News but something related to tech as I am a Techno Freak!!!1
