Finding Airfoil Data For Amateur Projects?

An anonymous reader asks: "I am an aerospace engineering student who is engaged in an amateur project. A major hurdle I am having is finding modern airfoil data which can be used for a non-profit project. As most aerospace engineers know, just about all modern airfoil data are guarded industry secrets, so building an amateur project that requires precise airfoil data is difficult, because of the lack of available modern information. There is plenty of dated airfoil data from the 1960s or earlier, but my project requires access to modern data. Note that I do not have access to a wind tunnel to procure this data on my own. Where would one find free modern airfoil data for use in an amateur project?"
