Few thousand bucks and a shop for such projects.
Don’t waste your time.Generally in Indian colleges,you are supposed to make a project in a group of 2-5 members,out of which only 1 is willing to do some work.
The mentor/guide rarely understands what you are developing because he has never been into project developement(thats why he’s a teacher).
At last marks are equally distributed to every member.Those who buy it from outside get more marks than those who try to develop something.
Better,learn for yourself.Make some personal projects about what you like.Learn what industry needs,if you wanna go for job.
Unluckily, all this advise is somewhat negative.But I personally feel,if you cannot change the system,learn to beat it.
