Cansat progess during quarantine
by the Canservationists
During quarantine the Canservationists team were split up, however, we’ve all been busy to ensure our progress with the Cansat wasn’t impeded.
Firstly, the code for each sensor has been written up, as well as the integration of all of them together. Currently, the sensors are been soldered onto our shield which will fit inside the can.
Case prototype
The prototype for the Cansat case has been 3D printed and is currently being adapted to ergonomically fit all of our equipment inside.
In addition, our parachute is being tested to make sure it travels with the minimum required velocity; a velocity given to us by the organizers.
Despite solid progress, we faced a few challenging but interesting problems:
1) The GPS module and the radio module weren’t able to work simultaneously as they both made use of the serial software port of the Arduino. To fix the issue, we connected the Arduino to the serial hardware port; however we can no longer use the serial monitor, but we can use radio transmission to view the data.
2) The SD card had to be changed as the initial model had working issues.
3) The code was too large and took too much space of the Arduino's memory, making it run unstably at times. Therefore, it had to be optimized. With some neat tricks, mission accomplished :-)
As the decision for the teams who are going to the launch is approaching, we are trying to finalize our work on the can, while polishing a few rough edges and start looking at how we can interpret and analyze our data in greater depth.
