I've been eager to use my raspberry pi for something a bit more interesting than making a temperature probe, or whatever people do with these things.
I purchased a tiny potentiostat called a "wheestat" and thought it would be cool to make a solar powered device that measures metals in water and
sends data to the internet. I can 3d print a cell and use peristaltic pumps to pump in buffer, internal standard, etc . . .
Is this even possible to do? Also, should I try to do this as a "project" at my university, or is it too amateurish

The design of a commercially viable sensor is anything but amateurish.
Low cost, rugged, reliable, repeatable. callibratable and sufficiently accurate,
anti-fouling, easy-clean/flush, pollutants and electrode-poisoning contaminants immunity, chemical compatibility ....
The rest is standard electronics, and a clever gui/hmi.
