How about tickets to a techno music festival or show? You could also consider buying her a vinyl record or CD from a techno artist she enjoys listening to.

Alternatively, you could also make a personalized techno music playlist for her and give it to her on Valentine's Day.
Or you can get her a star map with the date of your first kiss.
