Week 5: More Altimeter Work

Mar 25, 2019

Monday:

Today I collaborated with the SJSU graduate students and we began our code for the altimeter. Although I cannot show the code because the project is in partnership with SJSU, it is fairly simple, mainly consisting of a function to calculate when the slope of rocket altitude to time traveled—dy/dt—is negative.

 

Tuesday and Wednesday:

I continued my work with the SJSU students coding the software for our altimeter.

 

Thursday:

I began to learn about the hardware portion of the altimeter. This portion involves an infrared diode to create a transmission between the altimeter and the computer, so that the altimeter data can be viewed throughout and after the flight. The signals are frequency based, and different frequencies will correspond to different heights. Although I learned a lot about the hardware of transponders and altimeters, my group and I decided that the mechanical engineering students at SJSU would mostly cover the hardware portion of the project.

 

Friday: 

I continued to code the altimeter with the SJSU students. We completed our main function, and all that is left are the helper methods to the program. We plan to finish this code be next week.

 

Summary:

Although this week was undoubtedly less eventful than previous ones, I learned a significant amount about transponder signaling and altimeter coding. I plan to continue learning these same concepts next week, and then I will begin to build my model rockets to test for optimal fin configurations.

    It seems like you’ve learned a lot. Once you start building your rockets, can you include some pictures?

    Using frequencies to indicate different heights is a pretty clever idea. It makes sense to do the software side of the project since most students like us don’t have as much experience with hardware.

    Do you know the maximum range at which the altimeter can talk to the computer?
