brass pencil

“Rasas” is the Arabic word for “pencil”. Interestingly, it is also the Arabic word for “bullets” (plural), because a pencil can be the mercy bullet against darkness.

What is this site about?

This site is like a shared notebook, where I write, using a pencil of course :), about whatever interests me. It is mainly focused on electronics, embedded systems and programming. I have divided the site to three main sections as follows:

Here I share some of my learning journey. You will find here reviews of useful books I read and online courses I attend.
Projects rasas
The best way to learn is to do. Here you can find new projects with their detailed steps.
Tutorials and Guides
Researches and Tutorials
Here I publish solutions to some of the problems I face while doing projects.

Why is this site?

I have always believed that precisely describing a problem is a great step into solving it and that simply explaining the solution is a clear evidence that you understand it and benefit from it. This site is to share with you the projects I am doing and the problems I am facing in these projects. It is also kind of a motivation for me to continue working and I hope it motivates you and add to you as well.

Hot out of the Oven!
