This reminds me of http://nand2tetris.org/ (and the accompanying Coursera course). It's a fantastic course to learn about computing from first principles.
The course starts off with just a few logic gates and how you can combine these to make more complicated circuits. These are in turn combined to reach higher levels of abstraction, until you finally have a 16bit computer, with 16K of ram.
It's a really cool course that helped me flesh out my understanding of what's going in my computer.
Quick question if I may. I have a very keen interest in trying this course...is what you build (hack) using actual physical circuits / components? Or do you run it all in simulation?
