It's YOUR final project, you need to do it!. Copying someone elses project is cheating, if you can't do it yourself you don't deserve to pass your course!.
If you've already made three and they don't work, then you don't deserve to pass your course, what good are you on the job market with a qualification that you didn't earn, and that you can't do the work for?.
You will get far more help here if you post what you've already done, and what problems you have, and we will offer advise - otherwise quit your course and go work for McDonalds!.
How about you post what your idea was, what solution you tried, and what prob you observed. This is basically the way help is done all 'round the world.
I don't think Nigel Goodwin was being hash at all. He was being very patient by actually suggesting how you should go about getting help from us, but if you don't want to liston then you can do as he says and quit your course and work at McDonalds.
