Hi
Can you help me with some ideas for last year student project?
The project should be big enough so that i can write min. 50 pages of documentation about project and all technologies that are used for making it.
If you have any ideas it would be great, because i really don't know what to make for that project.

I don't have any ideas to throw at you, but...

I assume you're studying electronic engineering? At a 4-year university?

Do you have any hobbies or other interests? If so, maybe someone can come-up with ideas related to your other interests.
