A Raspberry Pi Pico is packed into this cannister designed to study air quality. Fun challenge designing multiple PCBs to stack into a soda can sized tube. From Kozma on Hackster.io:

Our Can Sat received the Outstanding Science Mission award. It recorded the air temperature, and pressure in order to fulfill its primary mission. We would have used the pressure to calculate the altitude, and we expected the temperature to drop as altitude increases. For our secondary mission, the Can Sat was supposed to record the PPM of NH3, and the air quality. Using the collected data, we would have studied the change in pullutants as the altitude increases. Although due to some hardware problems unknown to this day, most of the sensors partially or completely failed right during flight, but we managed to successfully correlate our data set with other existing ones which were relevant.
