Personally I prefer sci-fi that doesn't explain anything, just write the book from the perspective of taking these technologies for granted, it feels much more natural.
When I talk about cars I don't explain how a combustion engine works, I just talk its speed, its cost, its fuel-use etc. When I talk about my computer outside of my study (which is ICT, so obviously I do go in-depth there) I don't really talk about the details of chips, algorithms and all that. I talk about the latest games, random stuff on the internet etc.
Of course, if you have a scientist as one of your character then you should explain a bit more, but even then there's certain things that such a character will take for granted as common knowledge and thus not feature in his thoughts.
To me it just seems weird when a character's internal monologue goes on to explain how certain things work (which seems the most common way of explaining technologies inside a narrative). It feels forced.
What I would do is, with every explanation you write, turn it into a current-time equivalent (interstellar travel becomes travelling between continents, starship engines become jet-engines, lasers become black-powder etc.) and see if you would still feel natural explaining the mechanics at work there. Most likely it won't feel natural, in which case you should leave it out.
