I have built a digital logic simulator (called BOOLR) for a high school project with Node.js & Electron. I've worked on this for a year with 2 other guys, I have built the simulator and they have built a working 8-bits computer inside BOOLR. I am really proud of it, our mentor told us the project would be impossible, but we did it and we got a 10/10 grade. Project & download website: http://boolr.me On github: https://github.com/GGBRW/BOOLR, I'm new to programming so don't blame me for the ugly and messy code.
