8/27/20 WISRD lost some members because of the start of WIE which resulted in some groups downsizing or merging. I decided to stay in the Cosmic Ray Array Group, but the other members switched their projects. I am now the head of the Cosmic Ray Array Group. Online learning has taught me how to be productive while being online.

4/29/20 The poster presentation was 2 nights ago. I learned about exoplanets and the everyday life of someone who works at the NASA exoplanet archive.

4/9/20 Through the past few months, WISRD has gone online because of the recent outbreak of the COVID-19 Virus. I took a virtual tour of the LHC. I learned…

3/10/20 In WISRD, I am researching what a shooting star is. I was inspired to do this work because the other night I was looking at the stars and I saw a shooting star. I was able to see this because of the lack of pollution thanks to the COVID-19. I have learned…

2/25/20 In WISRD, I have expressed my interest in joining the board. I have sat in on board meetings and I am learning how a board works. Some things that I took away from my experiences as an observer on the board is how a decision is made, propositions and voting, and the different roles on the board. Throughout the next few months, I will be sitting in on the rest of the board meetings and preparing myself to be on the board next year.

The FRR (Flight Readiness Review) Presentation was a success! After many hours of practice and preparation, we presented to NASA and achieved an overall success. In the process of practicing and presenting the FRR, I learned how to present in a way that would create a positive impact on the audience.

2/10/20 Currently, In WISRD I am working on the Flight Readiness Review Presentation for the Student Launch.

1/23/20 After getting feedback about my work performance in WISRD, I have set certain goals for myself. 1: Writing journal entries about what I am learning. 2: Staying on the task at all times. 3: Take chances and opportunities even if it feels uncomfortable. I am going to apply these goals to my work performance throughout this semester.

1/16/20 The payload group is looking into the possibility of getting a reed switch to turn on the payload components. The reed switch is an electrical switch operated by an applied magnetic field.

1/14/20 Yesterday, we successfully presented our CDR (Critical design review) to NASA. After weeks of preparation, we presented with Notre Dame Academy. NASA specifically said that they admire the effort that WISRD put into addressing their previous comments. Yesterday was my first serious presentation in WISRD and I’m looking forward to many more presentations in WISRD. After the CDR, our team is going to be focusing on building the cosmic ray detectors for the WISRD data collection project. My part in building the cosmic ray detectors is part organization and navigation, and practicing soldering to eventually be able to solder parts onto a circuit board.

1/11/20 Practice presentation day for CDR NASA payload project. Today, team Athena and WISRD met at Wildwood at 10 am. We are running through the CDR to catch any errors and to practice for a flawless presentation on Monday.

Final draft: Retaining Payload Components slide #27,  #28 , and #29

Script for #27: We will have two cosmic ray detectors for a coincidence, and both of those detectors have the main printed circuit board, the SiPM printed circuit board, an SD Card printed circuit board, a plastic scintillator, and an Arduino nano on the board. They also have additional pieces like the 3-axis gyroscope and a battery. All of these parts are essential for our cosmic ray detector to function properly. The 3-axis gyroscope was added since the PDR. 

Script for #28: As you can see, these are the circuit board retainers. They have been accurately measured so that they fit inside the payload and properly secure the components. They are 3D printed using polylactic acid. PLA is a substitute for plastic. PLA is a thermoplastic aliphatic polyester derived from renewable resources, such as corn starch. Printing with PLA is beneficial because it is easy to print with as it melts at a lower temperature and is lightweight. When 3D printing, we used polyvinyl alcohol to create thin slots for the circuit board retainer. The PVA is dissolvable and saves time and resources because we do not have to sand it or cut it down. PVA is a water-soluble material. Because PVA filament dissolves in water, it is a great choice for a support material when 3D printing complex objects like the circuit board retainers.

Script for #29: Another component of the payload is the battery retainer. Like the circuit board retainers, this piece is 3D printed using PLA. It has similar properties to the circuit board retainers but instead of holding the battery horizontal, it is vertical. Since the PDR, we have 3D printed a new retainer to fit the top of the battery for stability.

How?

Why using dissolvable filament was beneficial?

1/9/20 Script for #37 CDR presentation: Another component of the payload is the battery retainer. Like the circuit board retainers, this piece is 3D printed using PLA. It has similar properties to the circuit board retainers but instead of holding the battery horizontal, it is vertical. We have 3D printed a new retainer to fit the top of the battery for stability.

1/9/20 Script for #36 CDR presentation: These are the circuit board retainers. They have been accurately measured so that they fit inside the payload and properly secure the components. They are 3D printed using PLA plastic. PLA or Polylactic acid is a substitute for plastic. It is made from fermented plant starch. Its benefit is that it does not emit toxic fumes when incinerated making it environmentally sufficient. Printing with PLA is also beneficial because it is easy to print with as it melts at a lower temperature. When 3D printing, we used PVA as a stable holder for the components. The PVA is dissolvable and saves time and resources because we do not have to sand it or cut it down.

1/8/20 As seen below, there is a centrifuge with a cosmic ray detector on one end and on the other a certain amount of mass. The centrifuge was used to see if the cosmic ray detector could stand the 13g’s of the rockets force during launch by rotating it around a fixed axis.

Centrifuge: “a piece of equipment that puts an object in rotation around a fixed axis (spins it in a circle), applying a force perpendicular to the axis of spin (outward) that can be very strong”.

1/6/20 It is a new year and I am starting to look at WISRD with a new attitude. An attitude of gratitude and opportunity. I am going to be present and focus on my current task in WISRD. After coming back from winter break, I am energized and ready to put effort into the student launch payload project for NASA. Before the break, I was working on counting and ordering the parts needed to build 10 cosmic ray detectors. The purpose of building these cosmic ray detectors is to take data from spread out parts of Southern California.

12/3/19 Today in WISRD. We faced a new problem with the payload. The cosmic ray detector has an Arduino which was supposed to be powered by mini USB connected to a battery. When testing to see if the cosmic ray detector fit in the payload, we saw that the mini USB port stuck out and did not remotely fit in the payload. After much research and consideration, we found a new way to power the two Arduinos using wires connected to pin 27. The objective was to have two Arduinos using the same battery without using the mini USB port. This alternative would fit in the payload and give us enough room. This is a 12v 1.5A supply which we would connect to the NANO Arduino using a connector and then solder it to Vin and GND on the NANO Arduino. We are using a 5V regulated external power supply (pin 27). References: https://www.youtube.com/watch?v=WZq8g782Sl8 https://www.instructables.com/id/I2C-between-Arduinos/

12/2/19 Today in WISRD. We just got back from Thanksgiving break and have a lot of work to do. I took on the task of determining the tilt for the rocket. I also have to write my WISRD job performance self-assessment. Progress report: Today I finished the part count and I determined what parts are needed and how many we have of each part.

CR DETECTOR PART LIST: what do we have and what do we need?

11/18/19: Not doing a presentation due to permit test to drive. I wrote a script for my part of the presentation: Script slide 18: Here are the initial designs for the payload. The main thing that the design revolved around was the two cosmic ray detectors. We figured out a way to put all components into the rocket. A system using poles and 3D printed holders for the components was used. After finding all the measurements of the components, we 3D printed slips to hold each component. The slips have holes for two poles which keep the whole thing stable. Script slide 19: these were initial sketches of how the instruments might fit within the payload bay, This is the scaled mechanical drawing of the payload holding the two cosmic ray detectors, one Arduino, and a battery that can withstand high altitudes as previously tested. Here, all measurements are recorded and this is the final sketch including each part and the size of each part in mass and in length.

10/17/19 Immediate Task List. Why are we using PLA plastic to 3D Print rather than APS, Nylon, wood, brass, or steel? Research PLA and write a paragraph explaining its characteristics. Why are we using it? Today in WISRD, I found the mass of the 2 CR detectors, the battery, and the Arduino. I have to reschedule my permit test for driving because it is on the same day as the PDR.

Reminders: Bring NASA release and wear WISRD shirts on Monday. GET MASS OF EVERYTHING ON FRIDAY – TAKE MEASUREMENTS ASAP

10/17/19 Today in WISRD, my group who is working on the Payload for the NASA student launch had a conference meeting where we discussed final tasks and the Gantt chart. MY TASKS: For sketches: Is it in the weight limit, Center of mass, 3+ sketches, Included dimensions, Sophisticated design, How is it fastened? We have to know the correct mass of 2 CR detector, battery, nuts, and rods (They have already done rods, but still do it. Design with measurements by Monday. 3-5 compelling reasons why we use the model – reduced mass, ease of assembly, price, temperature range (materials), strength in material (stress). 1# priority is mass. Then ease, Last is the price. Research PLA and Nylon ( PLASTICS WE USE TO 3D PRINT IN WISRD), Experience with this in a weather balloon

10/11/19 Today in WISRD, we have a lot to do for the payload. I continued to sketch three different ideas for fitting the two cosmic ray detectors and the Arduino. My 3d print finished and I tested it in the rocket cone. It fit and had the correct dimensions but now I have to figure out how to get the actual cosmic ray detector to fit into it. I will upload more sketches next class. To-do list for sketches: For sketches: Is it in the weight limit, Center of mass, 3+ sketches, Included dimensions, Sophisticated design, How is it fastened?

10/11/19 Today in WISRD, I printed the first draft of the 3D design that I made on Tinker Cad for the placement of the coincidence in the rocket. This was my first 3D printed project ever in WISRD. My group got started on our poster project.

10/08/19 Today in WISRD, My group started a Gantt chart for the poster project. I continued to sketch for the payload student launch. Our group is working on getting our name on the official NASA website because we collaborated with Notre Dame on this project and we were accepted by NASA in collaboration with Notre

10/07/19 Today in WISRD, The wifi was down due to privacy issues, so, unfortunately, I could not get onto the server or upload it to my journal. I sketched models of the rocket, specifically the section of the rocket that holds the coincidence cosmic ray detector, the Arduino, and the battery. We got a pretty good idea of how we are going to execute the positioning and placement of the cosmic ray detectors.

10/04/19 Today in WISRD, we continued to work and collaborate on the student launch. Today, I wrote and published a tweet about the progress and description of the payload project.

10/03/19 What I have accomplished and learned so far in WISRD: Techniques to solder in the process of making a cosmic ray detector. What a cosmic ray detector is and what its purpose is.

10/03/19 Tasks in WISRD: Download sketch up and start to sketch a model of the rocket for the payload. Step up and start a project to build a telescope. As I have taken the lead on this project, it is my responsibility to make a gent chart for everyone.

10/03/19 Today, my group and I got the news that NASA accepted the payload proposal! We have been working for the past five weeks soldering cosmic ray detectors, writing proposals, and ordering parts necessary to build ten cosmic ray detectors. The hard work has paid off and now we are going to Huntsville, Alabama to launch a rocket. The cosmic ray detectors that are not used for the payload will be used to create a network across southern California of cosmic ray detectors.

09/20/19 Today was the first day of our project to create a network of cosmic ray detectors all over Sothern California. All the parts were organized prior to starting and now that everything is ready, the process for building the first ten cosmic ray detectors has commenced.

09/19/19 Today in WISRD, we reviewed all the parts for the cosmic ray detector and organized them so that it is easier to know where everything is when the time comes.

09/16/19 Today in WISRD, I reviewed each and every part necessary for building ten cosmic ray detectors. After reviewing, I ordered all the parts on different websites.

09/13/19 Final edited version of the WISRD prior experience with cosmic ray detectors: WISRD first started working on cosmic rays in 2014 when it partnered with QuarkNet to detect and monitor cosmic ray showers. In 2017 WISRD became acquainted with Doctor Spencer Axani of MIT. He had built a cosmic ray detector for 100 dollars that seemed to give results that were comparable to more expensive detectors. WISRD built its first detector and launched it on a weather balloon in spring of 2019. With this experiment, WISRD will launch two detectors configured to count coincidence events that occur in both detectors. This improves the reliability of the counts. Also, WISRD will test the detector’s capacity to withstand up to 13 g’s during the launch.  If that is the case, the cosmic ray detectors can be developed as an individual wearable product to monitor exposure to astronauts.

09/12/19 Notes on past experience with Cosmic Ray Detectors: Doctor Spencer Axani of MIT did a study on Cosmic-ray detectors. He built a cosmic ray detector for 100 dollars that seemed to give results that were comparable to a more expensive piece of equipment. So, we downloaded the parts and ordered everything, everything was soldered. It was a single detector and was launched with a weather balloon in the spring of 2019. The result was that it landed in a naval base and all data was compromised and deleted. With this experiment, we are going to do a coincidence where we have two detectors where we have a simultaneous detection in order for it to count. We are interested in looking at if the cosmic ray detector can withstand the expected 12g from the launch. If that is the case then the cosmic ray detectors can be developed as an individual wearable product for astronauts to be taken up to space.

09/06/19 Today, we started to learn about soldering. It is an essential skill to have when building cosmic ray detectors. A capacitor was soldered into place as a way to practice how to solder.

We are going to launch a rocket. We are the instrumentation team and our job is to build two cosmic ray detectors for this launch. In addition, eight other cosmic ray detectors are going to be built and placed in places all around Southern California. The data will be collected and we will conduct a study about the cosmic ray showers.
