Camera ControlStill camera takes a picture every 8 secondsVideo
camera takes 10 minute video clips to prevent from turning offBoth
are controlled by digital pins
Post Launch Data ProcessingFile from data logger can be imported
into excel for analysisMATLAB was also used to analyze the
results
What went wrong?
ProblemsBattery enclosure on cameraVoltage RegulatorLow
batteriesArduino physical reset switchVoltage on arduino pins
controlling digital sensors
How can we fix it?
Circuit Board EtchingLess dependant on wire connectionsA more
reliable design would use one board rather than twoCant be easily
changed
Better CamerasVideo CameraStill CameraSome cameras can be hacked
to take pictures by themselves at a set time intervalWith better
cameras, they can be isolated from the rest of the system
OtherBetter TestingRedundant Power SystemsIs redundancy worth
the extra weight?Complexity vs Reliability
Future AdditionsPhotodiodesMore reliable sensorsDifferent
