evalynOS
This is possibly one of my most advanced projects that I have worked on and it is the one that I am most proud of.
This is my hobby operating system. It is still very incomplete but I like where I am at and I am excited to where it is going to get to.
You can the project on GitHub here and get the docs here
I have many many plans for the future but for now I will keep silently working on this project by myself and if you wish to discuss about this project with me you can join the OSdev Discord and take a peek inside #os-project-specific and my forum post #EvalynOS in there.
While it will run on real hardware here is a photo of it running inside QEMU with the KVM backend

Here is a video of it running doom aswell.
PS: That is not a random frame of bad apple there for no reason, The kernel is able to play the entire video and with PC Speaker Audio
