I’ve been working mainly on working with team Athena. They are launching a cosmic ray detector attached to a small rocket. This cosmic ray detector must be able to withstand 13 g’s, and I have been tasked with helping create the system that will be used to test if it can survive this. I have a large motor that I tested the speed of using a strobe light. Using the speed I found and the equation: (T²a)/4π², I was able to find how long the arm length would need to be to generate 13 g’s. I have also created a system to will report the RPM needed to reach 13 g’s at any given arm length. I have calculated that for an arm length of 10 cm, it will need to have a velocity of 344 RPM. The strobe light works at *100 RPM.

Presentations at poster night went well and I shared my work on the anemometer. I have begun to calibrate the anemometer and am working on collecting and analyzing accurate data. I am awaiting a new, more stable, design for the anemometer to continue my testing. I have also been making progress on implementing stepper motors needed for the fluid dynamics team’s rocketry project.

I have completed the program to print out the average of the wind speed every 500 runs of the program on the LCD. This allows the data to be readable by only displaying every few seconds. I am now waiting for the new anemometer to be built, so it can be re-calibrated and then the anemometer and display will be completed.

I have started my time at WISRD by getting reacquainted with working with Arduino. I am now working on my first real project by fixing the anemometer by rewiring and re-coding the work done by Spencer for the aerodynamics team’s wind tunnel project. I have now rewired all the components, so they are functioning. I have reworked most of the code, so that I can display values from the anemometer on an LCD. I’m still working our some bugs, then it should be usable again.
