Sept. 15-28
- Our team is offered the opportunity to take a part in the ROCKSAT-C mission
- We accept this as our senior design project
Sept. 29-Oct 12
- Intent to Fly approved
- Begin brainstorming mission goals
- Looked into additional missions from professors Dr. Mirotznik and Dr. Zang
Oct 13-19
- Begin CoDR preparations
- I took roles in both the Mission Overview and Design Overview
Oct 20-26
- Dr. Cotton made final revisions for our CoDR before we presented to Audrey
- Got a Geiger Counter to try and work with in the meantime
Oct 26-Nov 2
- Presented our CoDR to Audrey
- Begin preparations for PDR on Nov. 13
Nov 3-15
- Geiger Counter manufacturer info is mostly in Japanese, so will need to find translations
- code exists but excessive physical shaking of device returns inaccurate data
- Meeting with Dr. Zang involving HEMT transistors
- Presented PDR
- Begin preparations for CDR
Nov 26
- Continue CDR work
- Designing schematics for INSS/Power Board
- ***Next*** Make PCB if time
Feb 21
- Began schematic design for transistor IV curve analyzer
- Learning how to write code for transferring data into storage
- Coding voltmeter/ammeter to teensy
- Searching for alternative Geiger Counter
- Khalid and I are in communication with Scott McCracken, facility specialist at the UDel Nanofabrication Lab, regarding wire bonding the transistor.
Feb 28 - Mar 6
- Transistor is currently too small for wire bonding. Asked Dr. Zeng's group to redesign transistor.
- Soldered headers onto Teensy and accelerometers
- Teensy has working code
- Teensy able to read data from accelerometer
- Accelerometer data successfully transferred to and saved on MicroSD card
- Next up is to send a PCB schematic to be made to replace wires
Mar 7 - Mar 13
- Ordered parts for geiger counter and transistor circuit
- Drawing up low- level schematics for voltage sweep circuit
- Skeleton code for Teensy to capture current and voltage data
Mar 14 - 20
- Work on voltage sweep circuit
- Made ISTR Powerpoint to prep for report
- Presented ISTR
- Brainstorm ideas for Plug-and-Play board
Apr 4-10
- Power Regulator breadboarding
- Refining part usage to get better output voltages
Apr 11-17
- Solder power voltage board for testing
- Will bring as a backup board to Wallops
Apr 25-30, May 1
- Assembled DIY geiger counter
- Code written for DIY geiger counter
May 2-8
- Soldered voltage sweep board
- Made concept CADs of physical mounting locations for all parts within capsule
May 9-15
- Full systems test
- Physical parts are working, SD card not saving data
May 16-22
- Designing Plug-and-Play board
- Sourcing 9-Pin connection devices
- Editing SD card save/write code
- Drafting Final Report
- Preparing for FSMR (Final presentation for RockSat-C Program))
