I made a programmable computer from NAND gates
I am proud to present my solo hobby project NAND. This year-long undertaking follows the completed Nand to Tetris course, but ported to the web with its own runtime, user interface, and IDE. Using the "Load example program" selector, you can try out some programs I wrote on NAND's emulated hardware such as 2048, a genetic algorithm, and a manual stack overflow to corrupt the screen. Check out NAND at https://nand.arhan.sh Additionally, I've authored an extensive writeup about the project. Read about it on the GitHub repository's readme.
In plain words
NAND is a web-based computer emulator built from NAND gates, created as a year-long hobby project extending the Nand to Tetris course. It includes an IDE, runtime environment, and browser-based interface where users can write and run programs on simulated hardware. The project comes with example programs including 2048 and a genetic algorithm, along with detailed documentation explaining its architecture and implementation.
