Hobbies for teens boys?

I am a 15 year old boy that plays sports and video games but when i don't have anything that i can do i would like to have something that could be fun. I want to have a hobby were i can do something inside for it is going to be winter soon. If their is anything outside that you have suggestions for please let me know also. I play the cello i wrestle and i play soccer if that helps with anything. I have a basement were i could work on stuff if you have any ideas for building and thats about it, so if people can list some hobbies that i could do in my spare time that would be great.
