I can give you a few, but that would not give you as much as you would get from doing the following:

Click on "oldest" in the forum window and just start reading the subjects. You will see postings such as "tachometer" TCP/IP and so much more. When you see a heading that seems like a possible addition to your project list, read the postings, otherwise just click "next page".

If a few new subjects is enough, use "previous page" from here.

Welcome to the world of embedded, have fun
