Log for Jan 18, 2015

Mostly administrative stuff accomplished today. We are scrambling to get everyone's schedules organized, and determine what times we can all meet throughout the next few weeks.

It's a late night here for me. We should all be anticipating more and more of these, since our deadlines are not moving, and our personal lives (not to mention exam schedule) will continue to get in the way.

Cheers to all the late-night workers.

See you guys tomorrow!

Crazy Friday! (Jan 16)

WHEEEEW! These past two days have been crazy.
Today is Friday. Classes start on Tuesday. I ordered cabling yesterday. We're looking for houses in Alaska. We're figuring out everyone's scheduling. we're planning regular meetings. We're finalizing payload structures.

I was here last night with Chris and Michelle til 7pm.
I'm here in the lab now with Hamza, Arian, Daniel Canales, and Dr. Bering. John just came in.

This is gonna be crazy next few weeks!

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

Michelle Nowling:

Michelle is new to the team, but she is diving right in with her astronomy based project to be revealed this Friday. She has her very own website detailing all about the cool research she has already been apart of. We're so glad to have her on our team! Her website: http://michellenowling.weebly.com/

 Rachel Gamblin: 

A senior in Mechanical Engineering at the University of Houston. She likes to swim and has a long term goal of competing in a triathlon before she is 25. More reliably, she tends plants in the UH greenhouse, and studies for exams in the Engineering Computing Center. Also she has a tendency to talk for long hours about the various projects she's working on, so for any questions about USIP-UH, being a SWE officer, or UH engineering in general, feel free to contact her at rbgamblin@uh.edu or at (832) 890-9731. She is (normally) very friendly, and always likes to help people out! Obligatory: She is also looking to start a mechanical engineering career in the Aerospace industry.

Megan Pina (gray UH shirt):

Likely to be found saving a dog in need or putting out a family fire any given day. Studying Geosciences at the University of Houston.

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.
