Homemade 32-bit CPU and OS (2015) [video] launched on June 6, 2016 with 253 votes, #83 of 4,334 launches that month and more than 95% of that year's launches. The site was still online in September 2026, 10 years on.
In plain words
This is a video documenting the creation of a 32-bit CPU and operating system built from scratch. The project appeals to computer enthusiasts and engineers interested in understanding hardware and software fundamentals from the ground up. What stands out is the hands-on approach of building both processor and OS components without relying on existing frameworks, demonstrating how modern computing systems work at their core levels.

I've wanted to make my own OS since I started programming. Now, 5 years later, I did it (kind of). Sure, it is really basic, has very little functionality, but I made it and I'm proud of that. Oh, and I'm just 16 btw.
I built an 8-bit CPU simulator in Python from scratchOct 2025 · github.com · ▲72I built a tiny 8-bit CPU simulator in Python to better understand how computers work at a low level. It visualizes registers, memory, and instructions in real-time, so you can actually see each operation as it happens. You can write simple assembly code and watch how the CPU executes it step by step. The project is mainly for learning and experimentation, but I’d love feedback or ideas for improvement.

MyraOS – My 32-bit operating system in C and ASM (Hack Club project)Oct 2025 · github.com · ▲247Hi HN, I’m Dvir, a young developer. Last year, I got rejected after a job interview because I lacked some CPU knowledge. After that, I decided to deepen my understanding in the low level world and learn how things work under the hood. I decided to try and create an OS in C and ASM as a way to broaden my knowledge in this area. This took me on the most interesting ride, where I’ve learned about OS theory and low level programming on a whole new level. I’ve spent hours upon hours, blood and tears, reading different OS theory blogs, learning low level concepts, debugging, testing and working on…
We built an 8-bit CPU as 2nd year EE studentsJun 2026 · github.com · ▲108Hi! me and my friends together built an 8 bit CPU implemented in Logisim purely from scratch. The control unit of this system does not implement the generic microcode ROM or any kind of RAM. This was made purely from discrete logic gates and coded the system to run different programs. key features: Custom 16-instruction Harvard ISA, 8-bit fixed format, 4 general purpose registers Hardwired control unit built entirely from AND/OR gate logic matrix Dual-phase clocking to eliminate race conditions Bootstrap Control Unit that cold-boots via ROM-to-RAM transfer Early-exit conditional…

This is a 16bit CPU+Minicomputer from pure 74 series logic. It has user/kernel modes, virtual memory, prioritized IRQ's and DMA. It has a full C compiler and a unix-like OS. It's still in development.
