Here is a weather balloon project.
The goal was to measure atmospheric gravity waves by using direction tubes and thermistors to detect pressure differences between the two openings of the tube. Our apparatus measures the associated temperature fluctuation, and logs ADC readings to a CF card every half second. In order to compensate for balloon rotation, we stuck a HMC6352 digital compass in the payload as well.
