Best Project Ideas In CS, IT, Mechanical, Civil, Electrical, Electronics etc.

For Computer Science guys, You need not go anywhere in order to search for project.
I mean to say just look around and think what can be done programmatically which is being done manually now.
Take that as project and set up the things.
I am giving some examples :-
1. In many colleges, there is an option of filling electives (subjects) which is done on paper.
In most colleges everybody has email-id and password (college mail) So why not design a software (website) where student just logins from his mail account and when authenticated can fill his subjects.I think its pretty easy to do.
2. TimeTable Generation (----A difficult one----)
Just take the sufficient information as input and generate the timetable which will be really really helpful for all faculty members.
Your software should be able to generate multiple timetables for same inputs. The user can decide which suits nest for him.
Artificial Intelligence required.But no so difficult too.

If you dont really get what to do as a project then you can take the help of internet to look for projects.
Like :-
1. Development related (e.g Develop Chess which can be played over LAN along with GUI)
2. Research Oriented (e.g. Compression Algorithm Just study some research papers and add some modification which is helpful for some particular application)
3. Development Related like developing some browser extension, develop your own download manager like IDm for linux which can be integrated into browsers too.

Hope i am not off the topic.
There are loadz and loadz of things to do.Not countable......
