Can any one suggest some unique ideas for project work in hardware & networking or in electronics or in mobiles please? Answered

Have a look here!

With no idea of your skill and knowledge level

No idea of your budget or interests

No idea of the expectations of your educational establishment

I doubt anyone here can be helpful

You really need to look for a problem you can solve with your skills.

Look around Browse design sites, Spend a LOT of time wondering around the internet looking for ideas
