I am 3rdB.E(ece).I want to do mini project.please suggest me topics

You can Start on 8085/6 Microprocessor based Projects . Or else if your department allows you for fully software based Projects its better to go for Software projects

With due regard and apology, I do not agree with the suggestion of @BMTY.

Instead You must master MATLAB, Xylin, Microwind, C sharp and Tiny OS. If you can handle these,

Hello Mounlca you can take topic on social activity , government activity , or you can select business topic like project on particular business e.g. tata steel , Reliance or else any business leader . but its mostly depend upon you , find your interest and go for it if you have interest in busine
