If you want pacing & support for Nand2Tetris, Coursera has it split into two courses. I've done the first from NAND gates to a working CUP & assembler and can testify it's worthy. Coursera loves to have content sales, so if you're not in a rush you can pick it up for cheap and have their (petty yet ego boosting) certificate of completion to read over one morning with you Cheerios (and then put away in a drawer to be forgotten). Here's the two links:

Part I - https://www.coursera.org/learn/build-a-computer Part II - https://www.coursera.org/learn/nand2tetris2

Some day I hope to pick up Part II, but Part I was still a lot of fun!
