What is the best experimental method for determining the charge of an electron?

Homework Statement

I need to design an experiment to find the charge of an electron. And I have no idea how. Could somebody give an idea on what I could do?

You could try Google and search for experiment to measure charge on electron.
You will probably get plenty of references to Robert Millikan. That could be a good starting point.

I need experiment that has not be done already. Something similar to Millikan but not the same.
