I've done the Coursera course, Nand2Tetris, that inspired this website [1] and found it deeply intellectually satisfying and engaging. If anyone is interested in learning about the logical primitives that build up to a computer, and how they're implemented using logic gates, I would deeply recommend the course! ----------- [1] https://www.nand2tetris.org/

This is an attempt to make an educational online game, where the mission is to build a microprocessor starting from simple logic gates. Hopefully it is both fun and challenging, while at the same time educational about some of the fundamental principles of how a CPU works. It still lack some explanatory texts, but is should be playable as it is. It is inspired by the first chapters of the brilliant Nand2tetris course (and I have gotten permission to use…

I've been going through this with my kids and some kids from the neighborhood. They really dig it, especially the first part but then the steps become too large to comprehend and the 'show components' bit stops working. Some seem to check out around the half adder / full adder step, some don't understand why it could matter to create an optimal design and some are like fish in the water. I do my best to guide them through the…

I've just finished playing this awesome game again, it allows building computers as simple as playing factorio/satisfactory
