Oh gosh no. The first year... the rocket flew with no electronics. Then Covid happened just before that segment of the class was scheduled and it never flew with the electronics.
The board on the left is a Raspberry Pi Zero-W. A WiFi based Linux computer. The ribbon cable and tiny board is a video camera. The board on the right was voltage regulator/charging board for the LiPo battery. The goal
planned was to have a real-time video feed along with a real-time BMP280 pressure sensor for measuring altitude, and accelerometer to measure boost phase accelerations and duration. All to be sent down to a laptop via the WiFi. It would also be retained on the SD card
hard disk.
The eventual plan was to design various nozzles that would restrict the flow... thus comparing low thrust over longer duration versus the higher thrust / short duration of the standard 2-liter bottle outlet. In phase 1 - Nozzles like...

In phase 2, we also wanted to study the Aerospike designs using...

And for a final phase, we wanted to attempt a two stage nozzle. The part on the right is placed inside the 2-liter bottle and its density calibrated to float in the water nose down as shown. The nozzle on the left is screwed onto the 2-liter bottle and water filled and pressurized as normal. The theory being at launch it would need the large bore and high thrust to get it going and as it
burns off water, the float nozzle would descend down until the water flow sucks it down into the large throat and the last portion of the
fuel (water/pressure) has a smaller thrust, but also has far less weight to accelerate.
It was hoped we'd be able to see these thrust curves and sudden change in thrust curves to determine what portion of water was forced out in stage 1 versus stage 2... thus being able optimize future nozzles to maximize altitude determined by the pressure gauge.
