A lot of that sounds familiar. At least you guys are - well, guys. I was always the only girl in chess club, rocket club, science club, astronomy club, electronics club, etc. I'm old enough that back when I got a chemistry set, there were real chemicals in it. I did every single experiment. Some of them were really fun, smelly, loud, dangerous.
One of the nerdiest things I did helped a lot when I was older. I was a piano performance major at my conservatory, and it's always difficult to get access to rehearsal rooms at busy times. I was a little kid who took things apart. Once I took apart a piano just to see how it worked. And, put it back together. So, come college, I knew how to disassemble a piano just enough to make it unusable. And I carried the repair parts with me. HA! I always had a practice room!
