Homebrew computers

Of all my electronics engineering expierence, I cannot hide the fact that I am most intersted in digital electronics. I am also a retro PC hardware enthusiast. And one result of these facts is that I really got into building homebrew computers. This page summarizes all my current work.

Here's the list of homebrew computers that I built / I am working on. I recommend reading the backstory below as well.

Backstory

However, I would also like to share how I became interested in all of this.

My passion for electronic engineering started back in my childhood. I even went to a high school with an electronics engineering specialty. When I was young, my older cousin, who knows a lot about electronics, gave me an Arduino Uno (By the way, I owe him a big thank you because he helped me learn a lot about electronics from the basics). I immediately liked it. I played with it a lot, bought additional modules for it, and had a great time. This was when I was still in elementary school. I had already learned some C++ (mostly through self-study on the internet), so programming it wasn't very hard. It taught me a lot about digital electronics. I wasn't as into homebrew computers and digital electronics as I am now, but I remember experimenting with an SRAM chip from scrap by trying to write to and read from it with Arduino. It was all fun.

As time went on, I continued to learn more and more about electronics. By the end of elementary school, I knew quite a bit. Around that time, I discovered Ben's Eater YouTube channel, especially his 6502 computer on breadboard series. His videos are very detailed and easy to understand. Thanks to him, I learned a lot about digital electronics, and I got the idea to build a 6502 homebrew computer. However, I didn't have the required parts at that time. I decided to postpone the project. During that time, I also found a program called Logisim. It's an educational tool for designing and simulating digital logic circuits. Thanks to this program, I learned even more about digital circuits. I was also happy to find that someone had created a 6502 plug-in for Logisim! Even without the necessary parts, I could start experimenting with the 6502. Its implementation was pretty good, as I later found out physically...

And that's how I got into homebrew computers, by the 6502.
