Bergen STEM Amateur Radio High Altitude Balloon (ARHAB)

1. Create and send global P.O. for parts needed. ( William ) 2. Worked on error handling within the code. ( Patrick, Nick ) 3. Worked on checklists. ( Sofia ) 4. Untangled parachute and then tested. ( Everyone ) 5. Tested writing data to the SD card and onto computer. ( Patrick, Nick, Peter ) SUCCESS 6. Shelf designing liquefied our brains. So we decided to come up with a setup for the smaller payload box, thanks to Professor Benjamin. See PICTURE 1 for orientation. ( Patrick, William, Sofia ) PICTURE 1 :

1. Test and format SD cards (Format to MSDOS (Fat)). ( Nick ) 2. Watched videos from the Bergen Academy launch to work on the checklists. ( Sofia, Nick ) 3. Brainstorm for lattice design and component cases. Use PLA and MakerBot. Styrofoam payload box inside dimensions are approximately 10 1/4" X 5 3/4" X 15 1/2" ( Sofia, Nick, Patrick, William ) 4. Sketch and dimension ideas for lattice design. ( Patrick, William ) See PICTURES 1 and 2 5. "Unbrick" beaglebone #1. The beaglebone was not functional and is now fully functional. If the BeagleBone is "bricked" follow the instructions from the blog post on Thursday, July 2, 2015. Then follow the directions on  https://beagleboard.org/latest-images  to remove the # in order to flash the image onto the beaglebone. In the /boot/uEnv.txt file, the # must be removed must be in front of 'cmdline=init=/opt/scripts/tools/eMMC/init-eMMC-flasher-v3.sh' https://beagleboard.org/latest-images ( Pe...

1. Magnetometer was disconnected from the circuit but left soldered on the board in case we decide to use it again. The clock was integrated into the circuit. The old sound experiment was removed. See PICTURE 1 as a reference for what the front of the board looks like now and PICTURE 2 for the reverse side. 2. Tested functionality of the external thermistor . ( Patrick, Nick ) SUCCESS 3. Integrated speaker into the circuit. ( William ) SUCCESS 4. Tested functionality of the speaker . ( Patrick ) SUCCESS 5. Updated pressure sensor code to write out to one file. ( Nick ) 6. Worked on Checklists . ( Sofia ) 7. Re-soldered external thermistor and put sleeves on the wiring. ( William ) See PICTURE 3 8. Sent P.O. request for 4 32G Extreme Plus  MicroSDHC UHS-I cards. ( William )   9. Worked on error handling for external thermistor and tested. ( Patrick ) SUCCESS   10. Started working on error handling for the pressure sensor. ( Nick )   PICT...

1. Removed old sound experiment from board. ( William ) SUCCESS 2. Worked on timeline. ( Patrick, William ) SEE PICTURE 1 3. Removed magnetometer from the circuit. ( William ) SUCCESS 4. Installed clock into the circuit. Helpful link here .( William ) SUCCESS 5. Cleaned up code for accelerometer , added comments and changed the output from printing in a ZYX format to printing in an XYZ format. Accelerometer program finished. ( Patrick ) 6. Tested Pressure sensor and modified code to write out to a file. ( Nick, Peter ) SUCCESS 7. Tested clock integration. ( Nick, Peter ) SUCCESS 8. Figured out how to set date on the beaglebone. NOTE: Has to be in GMT and military. This link helped to determine the process. ( Nick, Peter ) 9. Worked on code for the internal thermistor and tested functionality. ( Peter, Nick ) SUCCESS 10. Worked on code for the external thermistor but did not test functionality. ( Patrick ) PICTURE 1 :

1. Started testing experiments for communication with the software. Current Sound Experiment will be removed from the board to be replaced with new sound experiment that is consolidated. (  New sound experiment ) ( William ) Speaker tested for production of 3.8kHz tone. ( Nick, William, Peter ) SUCCESS                    See Picture 1. Reference code for the speaker  here. Accelerometer test was a SUCCESS . ( Patrick )  2. Started "Build Checklist" and "Pre-Launch checklist". ( William, Hiten from Rocketry ) 3. Sent P.O. request for 4 go-pro cases. ( William, Peter ) 4. Sent introductory email. ( William ) 5. Sent reminder email to Luis for sound experiment order confirmation. ( Peter ) 6. Created a new accelerometer program but did not overwrite old accelerometer program. New program is accel_patm7edit.py ( Patrick )  7. Noticed that the accelerometer is in...
