IMHO, yes. See below.

Yes, straight to the trash can. (;-)

Yes. You want your project to be a success? Then do it on something you
ALREADY know something about. Doing a practical project to make
something that works is a job in itself; to add on top of that, learning
everything fresh that you need to know HOW to do it is two jobs and a
In any case, it seems futile to me. The way to make a good clock is to
synch it to one of the standard time or frequency transmissions, not to
a PC. But those 'radio clocks' are freely available at low prices, so
you would be re-inventing the wheel.
You might get extra credit if you designed and built an aid for the
disabled. If you explore that, go to people who know what's wanted but
isn't available; don't guess.
This is what happened to me.
'Can you make something to help communicate with multiply-handicapped
children? They have a drum, which they like a lot, but it's limited in
its communication skills!'
'Are these children both physically and mentally handicapped?'
'Yes, many have uncontrolled body movements.'
'OK, here is a chair, made from a wooden cylinder, cut away to form the
back and arms. In there, unwanted movement is restricted. The seat has a
wood rim, and a metal plate in the centre. Under the metal plate, is a
loudspeaker pointing upwards. This will apply the sounds in a
fundamental manner (;-).
It was very successful indeed, even though so simple, and I believe they
are still being made.
