I build and sell 3D printer parts, build robots, garden, play airsoft, modify and fix airsoft guns, shoot guns at targets, build modify and use RC airplanes/boats/airboats/cars, build model rockets and their engines, design modify build and fix electrical circuits, program, replace smart phone screens, etc. So basically anything that has to do with technology design aerospace and/or war games. Oh, I also ski and snowboard and know multiple ballroom and Latin dances (Chacha, Tango, Salsa, Rumba, swing, east coast swing, and Waltz). My room is a design laboratory, so my bed is on stilts to accommodate all my tools and storage drawers. I also play an assortment of videogames, but I don't consider that a hobby, I consider it more of an addiction

PS, no success yet with the model rocket engines, the rockets just burn up on the launch pad.
