Arduino MicrocontrollerProgrammable in C6 Analog Inputs/Outputs, 15 Digital Inputs/OutputsA multiplexer was used to extend the number of analog pins to 13Records time

OpenLog Data LoggerConnects to arduino serial pinsWrites to a standard text file

-
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 sensorsWorking Video Camera
