• Demo Day

  Stephanie Wallen • 11 hours ago • 0 comments

  We shared our prototype with the Caltech community and had a successful demo day. We really enjoyed sharing our work, answering questions, and connecting with others.

• Updated CubeSat Design

  Stephanie Wallen • 03/03/2025 at 23:39 • 1 comment

  We have changed our design. Instead of using corner pieces, we will now have 3D-printed top and bottom pieces. The walls of the CubeSat will be made entirely of foam, as shown in the CAD model we created using Autodesk Fusion 360. This new design is both lighter and more efficient.

• Possible CubeSat Design

  Stephanie Wallen • 03/03/2025 at 23:38 • 0 comments

  The corner pieces of the CubeSat will be securely screwed into place, holding the foam inserts in position. The foam inserts serve the purpose of insulating the system, ensuring thermal protection for the components.

• Light APRS Update

  Stephanie Wallen • 02/13/2025 at 20:40 • 0 comments

  We are working on integrating an APRS module into our sensor system. We have minimal experience working with this kind of device, so we are trying to learn using online resources. 

• Successful Integration of Carbon Monoxide Sensor

  Stephanie Wallen • 02/06/2025 at 06:42 • 0 comments

  We successfully integrated an MQ-7 Sensor onto our Arduino system. This sensor measures Carbon Monoxide and will be useful for environmental studies. 

• Housner Fund Update

  Stephanie Wallen • 02/05/2025 at 18:21 • 0 comments

  We are so excited to share that we have been granted money from the Housner Fund to complete our project. This will allow us to purchase the parts that we need to make this project a reality. We are grateful for the support, and are excited about the future of this project. 

• Successful Integration of Clock, Sensor, and SD Card Reader

  Stephanie Wallen • 02/05/2025 at 18:16 • 0 comments

  Using the Arduino Uno we successfully integrated the clock, sensor, and SD card reader. The real time clock will allow us to keep track of when measurements are being recorded. The sensor, a BME 688, allows us to get measurements like humidity, temperature, and altitude. Finally, the SD card will allow us to transfer this data back to our computer. Attached is the photo with our weather readings and their corresponding time stamp. 

• Successful SD Card Data Upload

  Stephanie Wallen • 02/03/2025 at 07:06 • 0 comments

  We successfully transferred data from the Arduino onto the SD card and opened the data using an SD card reader on another computer. We also successfully uploaded the data from the sensor onto the SD card. 

• Parallel Circuit

  Stephanie Wallen • 02/03/2025 at 06:39 • 0 comments

  We are setting up a parallel circuit so that the SD card reader and the sensor can both get 5V using the same port.

• Successful BME 688 Test

  Stephanie Wallen • 02/03/2025 at 06:01 • 0 comments

  We circuited the BME 688 sensor and used open source code to program it. We got successful temperature, pressure, and altitude readings.
