Sweet, thank you so much. I actually think I might still have the obsession that I had when I was a kid. (Gameboy) For some crasy reason I've been thinking about buying a rare $100 gameboy off ebay for a few months now. I've also been looking up all possible things I can do with/to them. Like installing a back light or making 8bit music. The only reason I'm not getting more stuff is because it all cost so much.
What happens when you don't 'fee'd your obsession?
Video Games can be a common special interest/obsession for those on the spectrum, I think it was for me at one point. Experimenting like you mentioned, and/or taking things apart, is also common for autistic. I do the same (though I'm not formally diagnosied, I have been unofficially) regarding money. I don't have the money for so many things so I just look up tons of ways to mod things too.
As for the other question, it depends if it calls you back or not.

My special obsession used to be art, but eventually I lost interest in that, "it didn't call me back", so I stopped feeding it and nothing bad happened. But now my special obsession is music, and if I didn't feed it, I'd go crazy.
