This is a brilliant project. I've toyed around with electronics and microcontrollers and I once wanted to build a full "desktop" PC with an STM32 and a PS/2 keyboard input and a VGA output. Unfortunately, school took over me and I left it. One thing that I am curious about though is whether you could use such a big project as yours for employment. E.g. if you had absolutely no formal qualifications and applied to a (…
Answering your question, well, even thought this is an electronics engineering project, I don't feel qualified to work with electronics professionally, for example, there's a lot of knowledge I lack. I do work as a software engineer and I have done a couple of interviews myself to hire people and I do believe this helps when applying to a job, I'm not saying it completely replaces your qualifications but it might at least give you an edge. I'm seeing this as someone who would want to hire someone skillful. A technical project certainly is on the very least a nice thing to have in a CV. Of course this is just my opinion. And if you are feeling like applying for a job based on your projects, just give it a go.
One advice I can give is: if you do have projects of your own, big or small, don't do it like me and keep them to yourself for years :P. I really had no idea so many people would appreciate my pet project.
