Write problem/project Goal
My objective is to help my team to create a hat that will light in depending upon different moods using led lights and a rubber snake

My First Task
Discovering the proper function of Diodes will help us to connect it to humans.

I found some reliable articles that helped me to get a better understanding of the diode.

http://insayne_kokane.tripod.com/diodes.shtml -helped me to understand the science and structure behind the diode

http://en.wikipedia.org/wiki/Diode -helped me to understand the different structures and purposes for different diodes

I thought my research was going to be much easier but once i realized it had to be more specific i definitely got more detailed in my mission. I also picked out some articles to give my team the gist of what i learned.

This weekend I sat a computer and started on google with the purpose of finding some form of understandable description of how a diode works.Once I realized there are many different types of diodes my research got a little more specific but I did not want to narrow down on any one type of diode because I was hoping me and my team would come to consensus. So I thought it would be best to have us all learn the science and technology behind a basic diode, look at the differences in a few of them and then decide on which one we will use for our snake hat.

Summary of actual work over first weekend
I figured out that an ecg sensor would be an easier way to detect emotion in people http://eurheartj.oxfordjournals.org/content/9/suppl_N/55.abstract-this article allowed me to see that if we could attach an ecg sensors to people while they have the snake hat on different levels of heart rates would trigger different lights to go off according to the persons emotion

Week1 Narrative
I found out that using electrodes not diodes would be the main way to connect to the brain but my team didn't look at my research on them so i fear we are behind in progress. I have already researched and found electrodes to be quite useful but my team was too focused on the wrong aspect of this project and now have given me the same task twice. But i did find that using an electrodes ability to sense even the faintest pulse to be incredibly interesting and helpful.

My Second Task
I am going to find a different way to connect to the brains waves although diodes seem like a good idea, i don't think its the only way to access the mind like using EKG electrode sensors, and find a useful product that can change a persons mood like watching tv or listening to music even sleeping.Also i want to see if there is more of a way to know for sure a persons mood has changed with out them telling us before we put the hat to the test so that our hat will be more accurate once programmed

Summary of actual work over second weekend
I thought we were going to sense emotions off of heart rates but my mission got changed once i saw this website. although my methods for changing mood have proven to be accurate and we can go ahead with using visual and musical stimulation.

Week2 Narrative
I went to union jacks and got them to save beer caps for me and i also found out about openeeg.com which may change the direction of our project

http://openeeg.sourceforge.net/doc/

this link helped me look at some specific differences in terms of our direction on this project and how this project has been done

My Third task
-i am going to get some ecg sensors and conductive gel to explain to my team how it works. i will also pick up a pace maker because i think its purpose is consistent with the sensors purpose for catching the heart rate and determining the changes in the heart.

-i will also go more in depth on how music and visual pictures change peoples emotions and when their emotions change their heart rate will change

- i will stop trying to only look at the heart rate aspect of emotion and research if there are other undetectable ways to connect to it.

Summary of actual work over third weekend
Through out this project i thought i was going to only have one task which was to create a certain type of sensor that would then be applied to my other teammates portion of the project, once i noticed that everyone was doing a lot of research and not really showing any sign of progress i decided to take the project into my own hands and on tuesday i will apply everything ive learned and constructed on my own to the finishing of this project.

Week3 Narrative
I decided to create my own pulse sensor from scratch because i assumed that everything that we would need to construct our very on mockup model would not be that hard to find and i turned out to be very much correct about that. This first link shows me the specific things we would have to make ourselves if we want to create a pulse sensor

https://docs.google.com/a/pulsesensor.com/document/d/1iOZv-ubb-cbfhLEYUawFpGXLxOGqULidrHE5UD5vx9s/edit?pli=1#

Once i got a pretty good idea about the materials needed and the process in which i would have to create the sensor i then looked up different ways to solder and this one seemed like the best fit for this type of miniscule project

http://www.youtube.com/user/digikey?v=QRW4gBcsRkY&feature=pyv&ad=5942790449&kw=soldering%20tips

this site helped me to find the designs and layouts for the pulse sensor so that me and my team would have a better understanding of how the sensor actually works http://pulsesensor.com/open-hardware/

this link is the simple shematics to the sensor and it is crucial to this project http://pulsesensor.files.wordpress.com/2012/02/pulsesensor-05-schem.jpg

I also designed how the snake hat could be worn and I think it would look way cooler, and be way more functional than some clunky hard hat

My Fourth task
I am going to make sure that the final product of the project is together and that no one is confused about the purpose of this project

Summary of actual work over fourth weekend
How is what you did different than what you planned?

Week4 Narrative
Tell a detailed story describing what you did for your team over the weekend.
