Week1 Narrative
I researched the Google to get the information of all about our polar printer. I focused more on the motor part such as the side of the motor, the number of steps per rotation and the drive cir-cult and voltage. I mainly worked on these kind of things how its single piece works. I found some of the formation of that but the description are written in foreign languages so that i had to look for more information which written in English. One thing that i had some complex is that i found many different types of motor models and i little mix up each other. The one that we actually need is the model of PM35-048-HPL2. i found couple information from several websites. I thought that has the right information of what i look for.However, it still doesn't have enough information and enough details. After finding this information, i tried to know how to control the speed of the motor, how it motor spin forward and backward. I also focused on how to connect its sigle wire stepper motor. One of the website that i found was licked by the following.http://arduino.cc/en/Tutorial/StepperUnipolar

Week2 Narrative
In week two,Base on our project we need some sort of angle brackets:therefore, i tried to design those angle brackets in the solid edge. We decided to design them in the solid edge rather than finding or building with other things,Another reason of why we choose to design is that because if we play the solid edge more time, we hope that we will be more familiar with that.Therefore, i spent some time on designing them in the solid edge. Sine we decided to design our brackets in the solid edge, everyone in our group has been trying to design them. Every time i work on designing something in the solid edge, what i always have some problems is that punching the hole on that. Similarly, I still have one problem with punching a hole on our brackets, however, each of us work on it so i think that we can figure that out how exactly do it soon. Also in week two, i tested our stepper motor with the 9 volt of the battery. The purpose of testing our stepper motor is wanting to know Is our stepper motor works well or not?,and also how our stepper motor spin including which way or which direct it's spinning. More particularly, how i started to test is that i connected that 9 volt battery to the motor and step the motor through its various rationals positions.More importantly what we have to know is that the leads on the stepping motor are color coded red, yellow black and orange and so i just power the red and black terminals with 9 volts and leave yellow and orange at 0 volt.Base on testing our stepper motor in week two, i try to explain more clearly about how i work because i think its stepper motor part is one of big challenges for me even code stuffs.

Week3 Narrative
In week three, what i did was mount our stepper motor and arduino motor shield on our hardware plate. After finishing some of our work such as testing our stepper motor with 9 volt of battery, creating our hardware plate, we decided to mount that our stepper motor and arduino motor shield on our hardware plate. We basically have two motors in this situation and mounted one on the left corner of our hardware plate and another one is mounted onto the right corner of our hardware plate. After mounting our both stepper motors, mounted our arduino motor shield d on our hardware plate as well. As we already see our hardware plate and its material, I mounted that our arduino motor shield on the center of our hardware plate because i though that we had to leave some space for mounting other materials such as our angle brackets which is not printed yet in the 3D printer. I basically used drill and drilled through our hardware plate two holes which holes are used for mounting those our stepper motor and arduino motor shield. Only after mounting those our stepper motor and arduino motor shield, we could decide that where we should mount our few brackets on it. After being done this sort of things, programmed an arduino to run both motors in unison and mounted the arduino and motor shield on the back of the plexi.

Week4 Narrative
In week four, we pretty much done our project. We are also done designing and printing our brackets so all we hand to do was mount those brackets on our hardware plate. I mostly spent my time on mounting our brackets and finishing our project page. It was the week fourth and so we need to have our finishing page so that everyone of us uploaded materials that we have on that fished page. I looked back my previous page and review about the stepper motors which i did research couple weeks ago and uploaded that information on our finished page. I also spent my time on sketching some pictures of polar printer. We actually need to put those sketching picture on our finishing page and our power point page. I already sketched some picture so all we need to do is put those pictures on our fishing page and our power point page.Now we still need two or three brackets more because our hardware plate is moved while it's spinning. We need those brackets to hold the hardware plate. We actually don't want that hardware moves SO that we need to design and print some more. The upcoming day, the brackets may be ready hopefully.

Week5 Narrative
In week five, We had our project day so that we had to present our polar printer. We prepared for that, so i basically sketched our polar picture on the paper to show on our project day. I took some picture of our polar and printed them to show on the board. Also that day i tested our polar again because we though that we may had to program that and make a run in front of the audience. I also worked on the finished page in that week. I uploaded some picture and wrote about it.

Week6 Narrative
in week six, what i basically did was that i work on mounting our another two bracket on the plastic hardware plate.Why we have to have those two brackets is that two hold our hardware plate. Without having these two brackets, our hardware plate shack while it's moving.I actually don't want it move. We basically have to brackets one is mounted on the right side of our hardware plate and one is mounted on the left side of our plate. We attached that brackets on our long metal,however, those two brackets have to move upside down while it's spinning so that i try to move those brackets smoothly while it's spinning. What the idea we had was that we get two little pipe on our little long metal piece to drive the brackets and our hardware smoothly to upside down.however i still have a problem with that because it seem like very tide and can't really move up to down, so what we think about was put two bearing for each side or fix that with different ideas. i think we can solve that problem soon because we get some ideas and suggestion from our classmate so it will be work out soon hopefully.

Week7 Narrative
In week seven, i was working on the data analysis assignment, What i basically did was i try to change the data to more improve and be a useful. The first part of my work was i copied and past to the data to the excel Microsoft office and fix that all letter and to be read and to be a useful. The original data is all mixed up and it look so confusing and unreadable, so i tried to organize them my best by using some kind material. The second thing what i did was add a value to the data for being easy to use. For example, sine i add the value to the data it's much easier to use what kind of job you interested in just type the little that leads you to there, if you in interested in electrical engineering, just type and that help you to get there. After that i work on making a chart which is very important to have in the data because that tell you how it is important and be interesting. I use some material to work it. For me this is kind of complicate thing because i have to know computer skill so fairly.therefore i just could done half way of them. Finally, i worked on the audience park and the tool used part. As we know that it's data may be interested by some people so that i tried to figure who going to want this data and why they want and then i tried to list some tools that i used to exam it.
