"Awesome! I really enjoyed this course. I have a much better basic understanding of what really is going on with a computer 'under the hood'. This can be a massive subject and I liked the way it was kept as simple as possible to get an understanding. Slowly piecing everything together to eventually have a simple computer. I honestly don't know how you could make this course better. Thanks for the awesome course!"

"Covers a lot of ground and the explanations are fantastic!

I love how the course builds towards concepts. At school, they tell you 'This is a transistor.' Then they tell you *how* it works and *why* it's useful. But this approach doesn't work --unless you're working with transistors every day, the knowledge won't stick.

So instead, Gustavo takes you on a journey to reinvent the transistor, step by step, and gives you historical context for every step. And you can feel how things just click, and how the new knowledge feels firm in its place."

"I've been trying to figure out how a computer works for a while and this course was a gem. Is a really good option for those who already know how to program but want to understand low level stuff. I will certainly buy other courses from this platform."
