Grad school general...discuss your phd progress, research, phd advisor shitting on you...

/sci/, I'm a 4th year engineering phd with ZERO fucking publications (other than a few second author ones which are meaningless). In my first year I had to change advisors because my first advisor was insane. The new guy I'm working with is a super nice guy and gives me funding despite the fact that I've produced nothing, but he doesn't help out with anything unless I get stuck (and usually his help isn't that great).

What the fuck do I do? I don't want to drop, but I want to finish in 2 years, even if that means finishing with 3 shitty conference papers. How do you guys get started in a new field? How do I come up with research ideas??
