Nice, I'd be interested to learn more about the balloon launch. 

Cloud chambers - We built several, from fish tanks, to peltier cooled, and petri dishes. 
I have few of the petri dishes left in kit form. 

As far as FM radio, the one I have been thinking is this


There is a interferometer that was setup to map the lower part of the ionosphere (I think) :


But I have not a good feel for how it would work. In the past we used analog TV stations that
are not around anymore.
