UG level chemical engineering projects (having some ICT relation as well)?

We are a group of 4 people.
Must have some ICT (information and communication technology) relation.
Should be cheap (in terms of cost).
Not to complex for us to understand (as we are 1st semester students).
Should be challenging (requires hard-work).

Like working out what project you can do ON YOUR OWN. Anything else is what we call "cheating".

I should add.

Come up with some ideas, and we'll happily critique and offer advice. We will NOT create a project for you.
