My digital logic course in college. Before that course I knew a bit about how computers worked, but after it I understood exactly how computers worked, and designed and implemented my own simple 4-bit processor. I built it from the ground up with logic gates. It had a huge effect on how I understood how electronics worked and enabled me to write my own NES game. The book and course material were lacking a bit, but the projects were great.
