I am just a big nerd. I have a lot of things i want to try for hobbies but time/space/money have made me unable to really get started in them.
Aside from gaming I the only real hobby i have right now is electronics. I am an Electrical Engineering Technologist according to my college certificate, so I'm always playing with something when i have a few minutes. I am "currently" (haven't had time to touch it in almost two months ) making a steering wheel for racing games. Since i had a few parts laying around I started to make one from scratch rather then using one of the existing projects which is NOT easy due to the poorly documented USB HID protocol especially for a force feedback device.
I used to play paintball and airsoft but haven't done either in a couple years.
I used to snowboard but have only gotten out a few times since i had kids (oldest is 8 ) I was even setting up to start making snowboards. I have enough fiberglass to make 40 boards and a press frame made from $600 in steel tubing just sitting around in the grandfather in laws garage.
I dirtbike when ever i can which is about twice a year as i have no where to store my bike so they are over 3 hours away at my parents.
I would say 3d printing is a hobby but really that is mainly used for making game pieces so it is basically part of my gaming hobby.
