I found the feeling sort of when I started playing with 3D printing, that led me down a rabbit hole filled with SBCS like Arduino and RPI, plus milling machines and laser cutters. It wasn't quite as exciting as the 1st time I connected my TI to a local BBS, but it was close the 1st time my RepRap started laying down filament.
