I have to prepare a project in Operating systems course.
Does anyone have any ideas?
It should contain 2-3 OS related parts like threads, processes, synchronisation, scheduling or something related to file systems.

I read about writing a kernel but I think that would be too difficult for me and wont be able to spare so much time also.

I need to use C or java and required to write a code of min 1000 lines.

Any topics or problems on which I could work upon?
