Log [12/09/2014]:
It's finals week, which is a mixed bag for most of us. Some are completely done with finals, or the end is in sight, so we have more time to devote to the project. Others are swamped and virtually unreachable. We send out our best wishes to our team, and to all other students going through the finals-week(s) struggle!

We have had some progress and updates this week so far, so here we go! 

Data:

Poster update: We did a mock presentation of our first draft of the poster that John, Erika, Daniel Canales, and Hamza will be taking to the American Geophysical Union (AGU) Fall Meeting in San Francisco next week. We got some great feedback and are looking into finalized printing options.

John Cao and Erika Marrero do a review our AGU poster with Dr. Dunbar and Dr. Bering

SD Shield update: We believe it was a hardware error (or soldering problem) that caused out heartache from Thanksgiving. Using another Adafruit datalogger shield we have successfully initialized the SD card and ran a very simple example sketch.

ADC Shield update: We have been fighting with the Iowa Scaled Engineering ADC shield and being baffled by the lack of response when we run the basic sketch that comes with the library. After a weekend of confusion, we verified that one of the jumpers on the board was misarraged. With that mystery solved, it is now time to delve into the library code and learn how to use this two-in-one multiplexer and analog-to-digital converter!

VLF Update: I worked with Dr. Bering today to get to work on the OrCAD layout file. We started from the OrCAD Capture project file, specifically the schematic: where we specific the type of connector I wanted to put into the circuit. However, when we tried to look at the footprint (i.e. the actual shape we wanted for the connector and where it should go on the board) using OrCAD layout, there was a conversion error. Dr. Bering understands what happened better than I do. We'll get back at it tomorrow.

DC EF Update: I'm not smart enough to understand what Chris is doing, but he says he feels really good about the work he's been able to get done with him and Dr. Bering in the lab at the same time, so I'm excited to his end result! He also is optimistic about having a test-able device by January 11th.

Goals For Next Few Days:
- Get ADC shield for Arduino to intake multiple sensors and write to SD card shield (test using power supplies)

- Finalize poster layour

- Print poster

Houston- we have a launch!

We don't launch rockets, we launch balloons. Sometimes those balloons have VLF wave recorders, sometimes they have arduinos, and sometimes they have air-tight Astrobiology sample catchers!
We had a launch just today with our very own Daniel Canales, the leader of the Astrobiology team which is attempting to create a device that will help look for creatures (generally microscopic in size) who can survive the incredibly harsh environments of the magnetosphere.

Check out the video here! https://www.youtube.com/watch?v=vOpdsAu_lxU&feature=youtu.be

The balloon went up... and then came back down. Into a rancher's yard! Negotiations ensued to retrieve the scientific device (and data!) from the rancher.

All's well that end's well, and now we are patiently awaiting the results from Daniel's report about this test flight!

Arduino logging shield woes

Worked with John Cao today trying to continue the work that Hamza and I did on Friday.

What we did on Friday:
We used a stack (Arduino UNO base, then Adafruit Datalogger shield on top, then ARD-LTC2499 shield on top of that) and connected a sensor (Gaseous Compounds NO2 sensor, which has two HI outputs and two LO outputs). SD card used was SDHC 32GB.
We powered the sensor through the 3.3V port on Arduino pins (SPI bus??), and connected all the GRND to various ground ports.
Then we put the HI inputs to the analog channels (A1 and A2) on the ARD-LTC shield. We used the basic example sketch that came with the ARD-LTC and its corresponding libraries.
Hamza set the output of the gaseous sensor to one of the pins and viewed the output on the serial monitor. He was getting 1's not the actual data, so we think it was right, but we're not sure.

What we did today (Monday):
We used the same stack described above, and tried get the SD card to work.
We used the "Datalogger" sketch example, set the CS pin to 10, and got the error "Card missing" telling us that it didn't initialize properly.
We used the SD card adapter to plug into my laptop and reformatted the card. We got the same error when we tried again.
We used the "Checkcard" sketch example, and got the same initialization error.
We used a different stack (Arduino UNO base, then Adafruit GPS+logger shield on top) and ran the "Checkcard" sketch example on this stack (which had a different SD card in it, SDHC 8GB) and it worked, revealing the file names and dates stored on the card.
We switch in the 32GB card to this new stack, and the "Checkcard" sketch example also worked.
We did NOT do any work with the MUX/ADC shield or code. Plan is to do that tomorrow with Hamza again.


So... It looks like there is an hardware defect with the Datalogger shield. Unless there is some connection the shield that we have to make in order for it to work that we are forgetting?? Which is a bummer, because it seems like we should buy more Datalogger shields, but what if they're just bad-quality shields with bad manufacturing? Or what if they're so delicate that we will regularly break them? I don't think this should be such a big mystery...

July 18th

Okay, we’re getting really close to the August test flight, everyone!

What’s Flying

Radiosonde

VLF Detector

Who’s Going

Hamza Ahmad

Erika Marrero

Daniel Canales

Rachel Gamblin

Darrell Anderson (ground support)

We still need to finish the MRR and the CDR. These need to be done in less than a week. Anyone not working on anything needs to obtain information and help put these together. If you have questions while you’re putting a slide together, ask them. Ask the whole experiment team, too; if someone is working and cannot answer, someone else may be able to. This is why we have the GroupMe chat.

We’ve made a lot of progress in the past two weeks and we’re really kicking it into high gear. But it needs to stay in high gear or else all of our hard work will be useless. If you cannot attend a meeting in person, please attend online. If you have currently filed for being unable to attend at all on a certain day please make sure to catch up with both the project management team and your own teams. If you are having issues and the project needs to take a backseat, even for two days, project management needs to know. Rachel and Daniel are happy to work with you if you’re putting serious effort into this project and something comes up. But they can’t work with you if they don’t know what’s going on. They need to be able to plan things and they can’t unless they know who’s on board.

Do your best to keep up with your Asana, it’s where I get these progress updates from. If they’re wrong, edit your team’s Asana and then email me. Those with no updates are ones that have not been edited in weeks, and I do not currently know their status.

Project Updates

VLF Detector: The team is currently assembling their prototype to put on the August 2^nd flight.

Gaseous Compounds: The team is currently compiling the radiosonde to send on the August 2^nd flight.

DC EF/Conductivity: The team is currently working on a circuit design, and plans to order it once it is finalized.

Spectroscopy: The team is currently discussing a project transfer. Details will be given once obtained.

Particle Detector: The team is currently attempting to order parts via Dr. Pinsky, and they are completing their calculations of the Simpsons rule with two pieces of software to ensure their results are accurate.

Astrobiology: The team is currently planning a full test in the lab on July 30^th, in order to be able to fly on the August launch.

TEC: (No update available)

Star Tracker: (No update available)

June 9th-16th

Okay, we've had a pretty hectic week past few weeks, and everyone can agree we have not been communicating. We have to communicate, people. If you're not receiving emails, make sure everyone has your correct email address. If you're paranoid, send a test email, make sure you receive a response. 

We have an August 2nd deadline. We have to make it. We do not have another option. We can make it if we budget time accordingly and talk to each other more. If you cannot make a meeting in person, please please please get on the Google hangout on the appropriate time and give someone (a faculty member) a time you will come to them and give a status update. If you don't know what times are good, ask. We have a vested interest, so do they. Sometimes we can't make meetings, which stinks, but it is a reality. That being said, don't make it a habit. If something comes up at the last minute and you cannot be there in person, get on the Google hangout. There is an app for the iPhone and iPad (for people who have these devices, yes, it is free) and it is easy to access on the computer otherwise. I do not know about Android devices but I will find out and edit this when I have. If you know you cannot make it in advance, notify the appropriate people and schedule to give a personal status update some other time during the week, preferably within two or three days.

Group communication is becoming a problem. Groups aren't talking amongst themselves or to each other. We will not make our deadline like this. Some people are being inundated with work while others who could be helping are sitting there twiddling their thumbs because no one has given them anything to do. During lab time, if you find yourself under-tasked, ask a group leader or faculty member what needs doing (they will have something, believe me, or they can direct you to someone who needs assistance). If you find yourself over-tasked, tell a faculty member or a project leader so they can assign someone to help you.

Alright, now with that out of the way, I have our status updates.

• Gaseous Compounds: A team member is procuring the UPOD from Colorado June 16th. On June 20th, they plan to retrofit it into a much lighter container, calibrate the sensors, determine methods for thermal insulation, and then use these methods to implement insulation in the container. Their planned test flight is Jul 2nd.
• TEC: The team plans to start testing their ordered model so they can be prepared for a test flight on June 30th.
• VLF: Upcoming tasks for VLF include making a VLF Gantt chart, filling out the VLF PDR questions, purchasing the iPod, choosing an appropriate antenna, observing the transfer function frequency response, reading the VLF design paper and then assembling everything with the Arduino.
• Spectroscope: A prototype telescope is built, we still need to mount a diffraction grating and sensor to it. The objective lens and ocular lens have been ordered. Three more lenses and a diffraction grating still need to be ordered. PVC pipe and styrofoam are being considered as possible materials for the casing of the instrument.
• Particle detector: The team is currently waiting on information from Dr. Pinsky on a new medipex sensor. They are in talks with Mr. Garbino about a particle detector and Raspberry pi combination. A Window Shield is being developed so the device can be handled with better care and the attenuation is being calculated.
• Star tracker: The executive decision has been made to use a Raspberry pi instead of an Arduino for image processing. The micro-schedule on Asana has been structured, and the necessary hardware components have been ordered. The team is now working on compiling the steps for a decent algorithm, and plan to use four or five reference documents.
• CPU: The team is currently reviewing their order list.
• Astrobiology: The team is currently replacing a part, which they expect to be replaced by June 18th. Along with that they are gathering various supplies needed for their instrument in order t begin lab testings in July.
• DC EF/Conductivity: The team is currently ordering parts and determining the power requirements. Soon they will move on to the circuit schematic and designing the layout so they can order a board with Surface Mount Technology.
• Telemetry: The team is currently reviewing their order list and discussing whether to have the telemetry system work through i-Met code or a new code.
  
  
  We have test flights planned for whatever projects are ready August 2nd through August 9th in New Mexico. Do your best to have your projects ready. The more we can fly, the better- it means if we messed up, then we know and don't have to panic last minute next year. Hope everyone had fun at the beach party!
