* Make an 8 bit computer https://eater.net/8bit — tutorial on making a simple 8 bit computer out of a bunch of AND, OR, NAND chips. Really helps you understand how computers work, what microcode is, etc. Honestly, building it wasn't quite as much fun as I thought it would be, but just learning how to build one was very useful.
