Summary
The first week we all competed with each other and came up with a couple of designs each. We all looked at the designs and chose the best 3. Then the 2nd week we all created one of the designs in 123d and posted them on our website. once we went to class we started on a decision matrix on the 3 top designs and found out htat the double- single- double design was the best course of action. so the third week everyone started to create the beams of spaghetti using the double single double design so we could start testing them for strength. Testing and building every beam one at a time we came up with the idea in the fourth week to hand out kits to the class so they could help us build them and we could have an unlimited supply of beams to BREAK! We waited for the other spaghetti group to create their arch so we could attach our designed beams to them and start testing a complete bridge.

Story
During the project we competed at first against each other on how to build the best design. then we choose the best design threw a decision matrix and concluded the double- sinlge- double design was the best mostly because of its strength. then we decided to mass produce these beams and did. We tested them for strength every test with our hands till they broke but it was getting very boring and was a very slow process so we all started to create kits for other people to make our beams for us so it wasn't just 3 people making beams but the hole class. so production would increase substantially. Also we waited for the other group to create their arch so we could start attaching our beams to them and start truly testing the complete bridges.

Decision List
HIGH is good

decided upon the double single double design

Material List

 * 1. List materials used, quantity, size, cost.

1. Box of spaghetti 2. Apoxy

 * 2. Describe what needs to be purchased in the future to continue working on this project.

Nothing needs to be purchased for others to work on the project. Because their is enough spaghetti and apoxy left for next group to use.

Software List

 * 1 2 3D by Autodesk
 * NCH WebCam Software

Time
41 hours and 15 minutes

Tutorials

Write problem/project Goal
Our goal is to design and create a spaghetti bridge by first brainstorming a way to make spaghetti attach to arch and base most efficiently

My First Task
I am going to create a design of where the spaghetti will attatch to the arch and also how to make the cable out of spaghetti the most effiecient and stable way

Summary of actual work over first weekend
I designed parts for the spaghetti bride where the cable connects to the arch and how to build cable. desided that spaghetti should be glued on side of the arch or drilled into arch, and have a solid spaghetti glued end to end or have a smaller spaghetti that fits into a bigger spaghetti which i think is the better design.

Week1 Narrative
I created a couple of design options for our spaghetti bridges. The first design is how to connect the cord of spaghetti to the arch just on the side. Or drill a hole in the arch and stick the cord inside of the arch directly. And my last design is to have to cords on either sideof the arch peice and glue them on the sides. we have not decided upn the design we will use becasue we have to test first before we should decide.

In addition to all of this I found different types of spaghetti that our group can choose from to specify to our agreed upon design.

I also created a tutorial of how to create a hole in 123d so the next group doesnt have the same problem with it as i did.

My Second Task
Design more parts to bridge and start testing some spaghetti design cords for strength

Summary of actual work over second weekend
I created a better and more abstract designs that combines all of the good aspects of the teams designs. Also build all designs and took pictures of then finished. then broke them with hands and found out which design was stronger or weaker. then took pictures of them broken and where they broke to show where the weak parts of the designs are.

Week2 Narrative
First thing i did over the weekend was design more cords to our spaghetti bridge in 123d. There was a double-single-double design, and a Single-double-single design. Bothe of these are made to make the breaking point of where the glue is to be not as weak and actually have the spaghetti break somewhere other then the glue. After I designed these I started preparin g to build them so i got my materials ready which were spaghetti, and bow and arrow glue which is what i used instead of apoxy just for testing purposes, and luckly was strong enough that the spaggetti broke somewhere other then where peices were glued together, but the final build we will uses apoxy. So the first thing i did was get the best uncracked spaghettiout of box to have consistant testing. Then I started constructing the designs I created. I started with the simplest, single-single design, then the single-double-single, and lastly the double-single-double. Once they were fully dried I started testing there strength by pulling on them. The first couple of times I pulled on single strands of spaghetti and the spaghetti broke becasue i was bending it by accident but after i got the pulling down and the spaghetti didnt break becasue of my bending I started to do it on the cords I designed and built. So I started with breaking the single- single.It broke just in high stress areas. It didnt take that much force to break it though probibly becuase it is a simpler and not very thought out design. So after that I broke the double- single-double.This broke just above where the 2 spaghettis on the outside and the spaghetti on the inside meet as expected and took quiet a bit of force to do. Then i broke the single-double-singlewhich broke just before the single peice of spaghetii reached the double peices. This break didnt take as much force as the double single double though so threw this testing the double single double design is the strongest.

My Third task
start mass producing spaghetti cords and also create kits to build a spaghetti cord to hand out to class so they can help me build massive amounts of cords for testing.

Summary of actual work over third weekend
I created a tutorial to make a kit to have the class help mass produce our beams to be attatched to arch. also created sample beam for call to look at.

Week3 Narrative
This week my job was to create a way to show the class how to build a spaghetti beam with our new design and i created a tutorial for the class which shows where to glue and what the design looks like when finished. I also created a final productof what all the beams should relatively look like so their is no confusion. Also I created a sample kitthat i want to get aproved by my team before i start mass producing. it consists of 7 peices of spaghetti even though our design only needs 5 peices but just incase a couple would break or if some are warped and we didnt catch it when we handed them out. Also has a link to our team page in it which leads them to the tutorial movie and final product picture that we want, just in case they cant find our team page otherwise. it has no apoxy because that would mean we would have to buy 100's of apoxy which is to much money. Inorder for someone to use our kit they need to have apoxy at home or use the schools. thats the only set back

My Fourth task
mass produce kits and also try to find a way to have mini apoxy kits also if possible so everyone can participate, also try to build a testing arch.

Summary of actual work over fourth weekend
I finaly got some apoxy to use on a peice of spaghetti. so i created a tutorial on how to use apoxy because i have never used before but it was pretty easy and also glued a peice of spagetti with it.

Week4 Narrative
Tell a detailed story describing what you did for your team over the weekend. I got apoxy for the first time and took a couple of trys to figure out at first because i have never used apoxy before so thats why it took a while. But when i got it down i thought it would be a good idea to create a tutorial about apoxy so other people could repat what I did except better even becuase they have a good tutorial. But simpley all you need is to get your materialsready before you start and have what you are going to glue ready becasue the apoxt sets in 3 minutes so you kindof have to rush and you mix an even amout of apoxy then put on desired thing to glue in my case was spaghetti and then wait an hour and its done. Also on another note, for ou rmass production kits, i found a link to cheap apoxyfor our kits since that was the only thing missing in our kits that was hjolding us back from handing them out. and because our group is staying with the bridge part but moving to the arch we will hand out the kits for everyone to use once the arch is completed, so jsut 3 people dont have to mass produce beams but 10 or 12 can mass produce them it will help our production, and testing speed an emence amount. Also ove rthe weekend i created7 beamsso we can test out an arch before we hand out the kits just to see how our beams designwere to hold up against real testing.

Engineering Projects/Coanda/Howard Community College/Spring2012/p501acm2.0

Problem Statement
To learn how to manipulate the Coanda effect such that static objects are able to gain lift and momentum.

Team Members

 * Marcus Watson
 * Chima Ezenwachi

Summary
Throughout the the latter three of the four weeks spend in development of this project, each member of our team had completed a separate task; all tasks were aimed in examining the posibilities of utilizing the Coanda effect in modern situations, as well as in future technology.

The first task dealt with the construction of two cardboard tubes; each of which contained a unique cut out that was used to expel air emitting from a air pump, used to inflate inflatable matresses. Two blades were constructed of aluminum sheet metal and duct tape, and bent, as much as possible to the curve of the tube. A skateboard like wheeled platform was constucted from detachable cart wheels and a plank of wood. The purpose of this object was to create a platform which sharp air flow, manipulated by the form of the air tube and blades would emit, and b powerful enough such that this platform could move without manual or mechanical assistance. During construction, various tests validated the cardboard tubes' function of demonstrating the Coanda effect. Both end of the cardboard tubes were enclosed with plastic cups. One example in particular, is how a small string could wrap around the from of the tubes utilizing only the sharp air flow manipulated by the curved blades. A demonstration can be shown here. The constuction of a complete Coanda effect based vehichle was the goal of this task; however, the hassles of final construction proved no good in proving the effect. The goal was to affix both cardboard tubes, and the air pump sources to the wheeled platform. The long drying Epoxy resin, poorly constructed cardboard lunette to hold the tubes in suspenstion and lack of room to fit the air pump between them impeded the testing and completion of the final design. Therefore, the design of the vehicle was alterated and an image of what would have been a final design was posted, instead.

The second task related to the project was similar to the first; the goal of this task was to utilize the Coanda effect to get a platform to move, but this time, not forward, but in a rotational (spinning) motion. Cardboard tubes, much like the ones used in the first task, were constructed to simply move objects about its form. This was done by cuting three simple openings in the cardboard tubes; two were cut on opposite ends (and on opposite sides) of the tube in order to release air emitting from an alternative air supply. As third was located midpoint between the two other openings, the alternative air source would be plug into there. Over the course of the second task, many ideas for how to supply a stronger flow of air were considered in the construction of the tube. The AC supply from a domestic house heater was used in order to create a stong air flow that could flow through the tube, was well as the air pump up hooked up to a 12V battery. A wooden platform, not wheeled like in the first task, was affixed with some handles. The goal of this was to secure the cardboard tube between the two handles such that when the platform began to spin, and the cardboard would not fall off the platform.

Story
Week1 - The first week dealt with deliberations among team members on how to continue going about the Coanda project; we ultimately decided to split the project up into two goals. Ezenwachi was responsible for the single tube Coanda effect platform, and Watson beacme responsible to demonstrating how the Coanda effect can move static objects.

Week2 - The second week started the design process. Several designs of devices that could demonstrate the Coanda effect were drawn, the most popular one recommended by class mates was implemented. Materials such as sheet metal and Epoxy resin were brought and some class resoruces were utilized as well. Due to some out-of-class issues, attendance by both team members began to shift thus causing a delay in construction of the tubes. Nonetheless, certain components were created, such as the wheeled platform, in preparation for testing. The recommended design was computer simulated via Google SketchUp.

Week3 - Construction and elementary testing proved the efficiency of the tubes in demonstrating the Coanda effect, the most notable achievement was having a string curve about 45 degrees around the form of the slot-wing tube. Power supplies such as 12V AC batteries (Watson), AC supply from domestic heaters (Chima) were tested in increasing the air flow in the air pumps, which proved successful; however, not enough to lift or move a static object from rest. In the mean time, the constuction of the Coanda apparatuses became hectic because of the poor materials used in creating them.

Week4 - During the final week, the results of our testing and experiments were reviewed and were documented. We were, nonetheless, able to prove that the Coanda effect can manipulate, with the help of a powerful air flow, the forms around it.

Individual Work

 * Marcus' individual story and work completed
 * Chima's individual story and work completed

Decision List
The consensual agreement to split the second Coanda project up into two tracks were based upon a deliberation on whether or not to continue working with the first Coanda project. In presentation of ideas, the team came up with three options:
 * Continue enhancing the previous Coanda projects from previous semesters
 * The Coanda hovercraft
 * The Coanda helicopter motor (favored by Chima Ezenwachi, and former team member Adam Rodriguez)
 * Create a new project based on the movement of static objects (favored by Marcus Watson)

We decided to spit the project to "cover more ground" in developing Coanda related prospects in technology. Which led to Watson developing a Coanda powered vehicle and Ezenwachi continuing with the development of the spinning helicopter motor.

Time
16 h 42 m

Tutorials
Online research was essential to the development of the project. Websites including documentation blogs of physicist Jean-Louis Nandin, the Meridian Internation Aeronautics Institute, and several YouTube videos were referenced throughout the course of planning, construction, and testing. Explainations of certain Coanda demonstrations are explained via our individual work pages.

Next Steps
Remnants of this project could lead to future ENES 100 project ides such as a wind tunnel using a reverse engineered air source, such as the air pump, along with a wheeled platform, to simulate flight. Another is to use the molded aluminum to create an air brush chassis that can be hooked up to an InkJet motor programmed to make unique designs on t-shirts, or maybe even cars. Despite the mild success of the intended projects, our team was able to demonstrate the Coanda effect through uncommon means and provide a idea basket for how to manipulate the Coanda effect to enhance future technologies, and to better society. Research, design, and the implementation of planning are critical aspects of a future Coanda engineering project.

Problem Statement
To create an arch and implement it with the other Bridge Team to compete in a competition that will hold the most weight.

Team Members

 * Sam Ang
 * Mirza Baig
 * Nathan Renkenberger

Summary
The overall objective was to create an arch from noodles. At first the group started with ziti noodles. A cylinder type noodle that is fairly strong. We ran into trouble due to the large gaps created between noodles when forming around the arch. The large gaps made the structure really weak and all the strength of the arch was reliant on the glue. The team moved to a different type of noodle, the penne noodle (a noodle that is cylindrical but with cuts on both ends). We tested different structure types but in the end it was a bit stronger but still too weak. The next idea was to create a box that can hold a ziti noodle and cut it to the right degree. This way all the noodle would be flushed together not relying on the glue because the noodles' surface will be touching each other and cause friction that will try to hold each other together, rather than just relying on the glue to hold the structure together.

Story

 * WEEK 1:

During this week team member came up with design ideas for the arch. We all started with ziti noodles as the main structure noodle. One member's ideas were to place a smaller cylindrical noodle inside the ziti noodle in order To increase strength. Another member decided to use thin flexible noodles on the inside of the ziti noodles to allow the ziti noodles to form around the arch and add extra support. Another member looked into arches that were not made of noodles and decided to implement those ideas using noodles.

 * WEEK 2:

Over this weekend team members tested their design ideas and tested different noodle types. All three members came to the same issue when it came to gluing the noodles together, there is not enough surface area for the glue to work on the ziti noodles. This issue leaves gaps in between the connection of noodles and in turn reduces strength. A team member decided to try a different noodle type, penne, that may solve that issue. The penne noodle has slants on each of the noodle and is similar in strength and size as the ziti noodle. Giving more of a catching area for the glue. One team member's idea was to file down each individual ziti noodle to an exact degree to fit the arch. This would remove all gaps in between the noodles but increase build time. In class the team used penne noodles with the fettuccine noodles inside to link them together and provide support. However, there was no more epoxy to fasten the noodles together.

 * WEEK 3:

Team members got together to test their different ideas on the arch, design a box that can be used to quickly grind down ziti, and to continue the penne fettuccine arch. The team continued building the arch by placing penne noodles on fettuccine. Members created several strand using this technique. Each end of the noodle was placed in the glue then onto the fettuccine. The end result was a weak structure that broke easily.

 * WEEK 4:

Team members reconvened and used wire instead of fettuccine. Since wire cannot be part of the structure it has to be removed. When we finish constructing the arch with wires inside, the wire got glued onto the noodle. We tried a series of idea on how to implement the wires and noodles without having the wire get stuck to the noodle. A member pitched the idea of wrapping the wire in wax paper because epoxy doesn't stick to it. We built an arch with wire wrapped in waxed paper, however, due to time we were not able to build a lot of arches and stick them together and test its strength.

Decision List
We had two different types of noodles we could use to build the arch, Penne Noodles or Ziti Noodles. Both has their own advantages and disadvantages. The Penne Noodles has the slanted edge already made which we hypothesized that could easily form the arch because it is already slanted. Also, we thought it would made it more durable because more of the surface of the noodle will be in contact rather than having gaps inbetween the noodle and the only thing holding them together is the epoxy glue which the glue can easily be bent and brake apart. Below is the decision matrix we created and requested friends and family to help us out. Construction Time referes to how fast we can contruct the arch with the use of this noodles regarding how much work we have to do, such as grinding the noodle down, constructing a box to cut the noodle at a specific degree, pasting each noodle together. The Structure Strength referes to the overall strength of the arch and the stability, durability, and strength of the geometry of the noodle.

With these data, we decided on to move forward with penne noodles. We also had to decide upon which design we should construct.

Design 1 - Side-by-Side Structure

After constructing this during the first week, this was tossed out because the amount of noodles needed made the arch too heavy and unstable.

Design 2 - Head-to-Toe Structure

Design 3 - Criss-Cross Structure

Majority of the time, we were building on the head-to-toe structure since both design 2 and design 3 requires arches that are head-to-toe structure. However, we believe design 3 will work the best because it will be light and thinking about the physics of it, the tension force inbetween the arches will hold them together well.

Material List
Materials Used:
 * 1) Epoxy Glue
 * 2) Ziti Noodles
 * 3) Penne Noodle
 * 4) Fettuccine Noodle
 * 5) Arch Board
 * 6) Wax Paper

Next Steps

 * 1) Applying the epoxy is the toughest part of the project
 * 2) Find the best angle to grind the pasta at to have it mesh properly.
 * 3) Wrap a bunch of wires in wax paper, insert them into the grind noodles and create several arches and test its strength.

Write problem/project Goal
To design and create a sturdy spaghetti arch.

My First Task
I am going to look online and develop design ideas for the arch.

Summary of actual work over first weekend
I looked online and searched for spaghetti arches. Most arches online had limitations on the structure from how many noodles to how much paste is used. I then looked online at arch bridges and their designs.

Week1 Narrative

 * I started searching online for spaghetti arches and most search results had building restrictions on their projects. So far the only project limitations we have are the arch. I continued with the online search to find complaints about curved noodles being weaker after the curving process. I came to the realization that the strength does not have be reliant on just the curve. I searched online for bridges with arches to gather ideas. I looked at the red cliff arch bridge that has a road on top instead of the bottom. The I looked at the Dunn's Bridge in porter county and has the road at the bottom of the arch. http://www.historicbridges.org/indiana/dunns/. It connects to an identical arch. It has multiple support beams between the curved top and bottom. Maybe a good starting point with the spahgetti bridge.

My Second Task

 * Try different noodle types or modify noodles to see which would be sturdiest for the arch.

Summary of actual work over second weekend

 * I tested different noodle types and came to the conclusion that maybe ziti noodles are not the best option but penne noodles are.

Week2 Narrative

 * I started off by looking at the pictures of the current spaghetti bridge winner. I couldn't tell what type of noodle they were using. So I set off by trying different type of noodles around the arch of a wooden table. The arch from appearance appears to be similar to the one used in class. I started with regular spaghetti noodles but they couldn't be bent around the arch without breaking. Tried lasagna noodle sheets but had the same result of breakage. Went to the noodle type (ziti) we experimented with in class. The noodle is sturdy and doesn't need to be bent due to it's size. However, when it comes to gluing the noodles together, the noodles are not flushed with each other. This allows the noodle to be easily separated from each other. I decide to try an file down each end of the noodle to fit the arch perfectly. This took a bit of time with a regular nail file and some of the noodles would crack and break when using a knife. Next I tried Penne noodles, they are just as strong as ziti noodles but they come with staggered cuts all ready in them. Penne Connection.jpg
 * These noodles do not fit the form of the arch perfectly but they have more of a contact surface area making them stronger when glued than the ziti noodles.

My Third task

 * I am going to design a box that a noodle can be placed in. Which will allow each noodle to be filed down to the exact angle each time.

Summary of actual work over third weekend

 * I created several designs for the box and attempted to construct but will have to finish in class.

Week3 Narrative

 * I started with creating a design that would be used for a single noodle. The box design will have a metal face so that the electric powered file wont degrade the box and will let it be used over an over again. The sides will be wooden so they can be cut easily to fit the degree. SKetch.jpg side block will be cut to 1.5" and the sides will have a 4.3 degree cut for the metal face to lay on. The bottom piece of wood is measured out to be a bit longer than a 1.5". The design requires a back and a middle piece with an identical hole in the front for the noodle to sit. There is no top to the box so that the user can hold onto the noodle while it is being grind ed down. I started to build the box with wood, sheet metal and glue. I tried sawing the wood with a saw but the saw broke. I used a knife but the would chipped. I decided to make all the measurement at home and all the cuts at school.

My Fourth task

 * Create new designs that would incorporate the filed down noodles and construct the box"

Summary of actual work over fourth weekend

 * I came with ideas of the arch designs that would solve the issue of sturdiness and will allow for it stand up on it's own. I also constructed the box and tested several noodles.

Week4 Narrative

 * With one arch structure it is very weak and cannot stand up on is own. I went to the next idea of connecting two arches side by side but will have the same issue of the arch falling over. I went to the next idea of connecting the arches together with joiner noodles. However, I was thinking of how the joiner noodles would have gaps between the ends of the noodle and the side walls of the noodle (will not increase strength). Making the joiner noodles not stable and adding extra additional weight. Joiners are needed to make the structure stand up by relying on each other. There only needs to be a few joiners to connect the arches together. The final design will have four arches, two of which are connected side by side. Next thing I did was finish creating the box according to the design. I cut the side wooden pieces to 4 degrees. Then glued the sides to the base. Added a rear piece and center piece. I drilled a hole in the metal piece that went though the center piece. I then used the grinder to grind down several noodles. After several test I was unable to tell if the noodles were cut that degree.

Write problem/project Goal
What is your wording of the overall problem/project goal?

To create a spaghetti arch that will support as much weight as possible.

My First Task
What are you going to do for the team this first weekend?

I will be designing numerous arch design and then will be discussing with my team mates about each other's design. Brainstorm ideas on how to attach the spaghetti together.

Summary of actual work over first weekend
I was assigned to design various way to attach spaghetti together.

Week1 Narrative
Over the weekend, I brainstormed idea on how to attach spaghetti together. Some of my ideas were to use tape and rope, but those did not hold, they were to weak and were not stable enough. I came up with a design on how to attach the spaghetti together which is shown below.

Basically, there would be a series of spaghetti inside the an outer spaghetti noodle, where there are glued together. This is an effective way of attaching them after analysing the spaghetti noodle, it is hollow inside where it would be unstable and would be easier to break because there is nothing to strengthen the inside of the tube of spaghetti, where if you filled the inside hole with another spaghetti it would be stronger because the hole would be smaller and filled where it can hold more force. This is a picture of our working progress of our arch, It has successfully curved because we do not want it to be too flexible where it can break easily and we do not want it to be too stiff where it could not curve with the arch.

My Second Task
I plan to test the strength of the arch by putting weights on and analyse the weak points and improve the structure of the arch

Summary of actual work over second weekend
Over the weekend, I brainstormed a series of designs to hold and strengthen the arch.

Week2 Narrative
Over the weekend, I sketched up a series of designs to be constructed and tested to see which ones would hold the most tension. pictures are shown below.

This design was to glue a series of noodles side-by-side, but figured this would not work because I had to glue a lot more noodles and it created more weight which is bad in competitions. This design came up, because I wanted the noodles to have more surface area touching each other rather than having the bonds be held only by glue.

This design was better because it created less weight for the noodles.

This design has not been tested, but I believe it will create even less weight.

During the construction, I found out that just having the flat ended noodles being attached with glue did not hold as well because there is no surface area for the noodles to be held on. The only thing that is holding the noodles together is the glue where there are gaps inbetween the noodles when we want to bend the series of noodles to form the arch. Picture shown below.

flat straight noodle has gaps in between when glued together to form the arch which makes the bond weaker because only the glue is holding them together

After testing out the structure on top, I recorded my frustration and tried to figure out a way for the noodles to touch each other more to have more grip on each other.

Therefore, with this problem, my team decided to file every single noodles at a certain degree or buy those slant-edged ziti noodles to have the surface area hold each other to create more grip between the noodles and be able to bend naturally, instead of forcing the noodle series to bend.

Slant-edged noodles have more surfaces touching each other, created more grip on each other, better than just having the bond held by glue.

When attaching these slant-edged noodles, we can easily form its arch without giving it tension between the noodles and the glue, just need to rearrange them to make them touch each other more and start glue them together

My Third task
Over Spring Break, I will be meeting up with my teammate to begin filing noodles and constructing the arch with a wire inside the noodle, and hopefully have time to test the strength of it.

Summary of actual work over third weekend
During Spring Break, I built the arch and began testing the strength of it.

Week3 Narrative
Over the break, I met up with my teammates on Thursday and Friday to finish glueing our arch from last week due to lack of epoxy glue in the workshop. One of my team member bought the epoxy glue for us to use. During the glueing phase, we came across some barriers, that we could not just glue on top of our pre-arranged noodle arch because some of the noodles need to be replaced because there are gaps between the noodles because they broke when moving the arch from school to the house. So, we had to remove the noodle from the fettuccine, throw away the broken piece, put new ones it, and made sure there were no gaps and begin glueing again.

As I finished glueing and waited for it to dry, I decided to test out the strength of the noodle arch by applying some weight to it. I took off my shoe and weight it, it weights about 0.5 lbs. I tied a string to the arch and place my shoe in it, it broke in three different parts. I analyzed why it broke and figured that the noodle arch broke where there was little epoxy glue applied. This meant that the fettuccine just made the arch heavier.

Seeing our first design failed, I continued to brainstorm another design. This design consist of using wires instead of fettuccine, where they did the same function to form the arch, and at the end of the construction I will be removing the wire from the inside of the ziti noodle. I came across a problem that the inside of the ziti noodles would stick into the wires as I glue the ziti noodles together. One of the possible solutions I did was to cut the wires into smaller pieces to easily remove them, but that did not work at all, it was still impossible to remove the wires from the ziti noodles. Another solution, that I made it possible was that wrapping the wire with wax paper, just like wrapping the arch board with wax paper so that the ziti noodles would not sick into the wire and unto the arch board. I began inserting the wire wrapped in wax paper into ziti noodles and will be gluing and testing the strength of the arch next week.

My Fourth task
Create a series of ziti noodle arches with the use of wires inside to form and hold the noodles together and later remove the wires inside and glue the arches together and test its strength.

Summary of actual work over fourth weekend
How is what you did different than what you planned? During the forth week, I helped my team mate build the box to find the best degree to grind the noodle. I also, tested out different ways to built an arch.

Week4 Narrative
Tell a detailed story describing what you did for your team over the weekend. After observing where the arch broke and realizing that the fettuccine noodle did not help support the strength of the arch where it only created more unnecessary weight. I thought instead of inserting wire wrapped in wax paper, I could just tape up the noodles on the arch and glue them. So as I built another bridge where there was nothing inside of it, I taped a bunch of penne noodles on the arch board trying to limit the amount of gaps in between and then begin gluing together the noodles.

During the process of gluing, I had difficultly because as I glue, each noodle would move sideways and will not align together. Some arch will move to the right or left and will misalign from the previous noodle. Also, it created gaps in between the noodles because there wasn't any pressure trying to stick the noodles together, it was lose and each noodle aren't really touching each other. After seeing this failure, I realized I have to really use the wire wrapped in wax paper because wrapping the wire in wax paper and inserting it inside the noodle, it would fill in the hallow space. Filling in the hallowed space would give me more control over the position of the noodle in the arch. The noodles would not easily slide off the wire or slide off to the left or right and make it misaligned. I would also be able to make each noodles touch each other and be able to easily glue them together. The only difficult part was removing the wire off the noodle because they were tightly filled in the hallowed noodle. I had to make small portions of the arch and then later glue them together. I only created one arch, I have to create a series of arches to finish this project.

I also made a tutorial video on how to wrap wax paper onto the wire.

User:Mwalker/enes100/myWorkWindTunnel

Write problem/project Goal
Many projects require wind tunnel testing, a need the lab currently does not provide for. Design and develop a Wind Tunnel for Projects to be tested.

My First Task
Look up on how to get the Large motor and 80 amp ESC to work in our project

Summary of actual work over first weekend
Looked up information for ESC, and starting trying to get it to work

Week1 Narrative
Found previous work done on the project. The motor and ESC were used in the HoverCraft project beforehand, and they got it to spin up and control the speed with a potentiometer, which is exactly what we need.
 * Team Page
 * Shortcut to user page of how he did it

Here is an arduino programming script to see if it can control our ESC
 * Thunderbird 9 ESC Setup

I also looked for one of these to possibly purchase, but did not find one.

My Second Task
Get the Motor and ESC to run.

Summary of actual work over second weekend
I got the Motor to spin, and cataloged the steps taken and some information about the Device. A tutorial (or addition) should be created soon.

Week2 Narrative
Important things I've learned:
 * When the arduino stops responding from com4 on the computer, the best solution is to cut all power to it, (unplug it from all things that power it) and then plug it back in. So far this has worked every time.
 * The arduino digital output is a digital square wave, and the value it reports is associated withe the length (duration) of the high pulse. The period does not appear to change.

A crude step by step instructions for getting the HexTronic HTX 80 ESC and Motor to run off of the arduino and power supply.
 * Open the arduino software and configure it to the specific arduino you are using. (I used an UNO)
 * Open the knob program under File->Examples->Servo->Knob
 * You have to change some parts of this program. There version I used is here (link not yet active)
 * Create a new line in setup, under the line " myservo.attach(9);" (no quotations)
 * This New line should read: "Serial.begin(9600);" The will get eh arduino reporting back to the computer through the USB. The value is the rate of transmission, it may be changed (to the appropriate values) to whatever suits you.
 * Create a new line in loop, under the line "val = map(val, 0, 1023, 0, 179);"
 * This new line should read: "Serial.println(val);" It will communicate the value that is going to pin 9 and display it on the "com" window of the software. Access this window through Tools->Serial Monitor or by clicking the symbol on the upper right of the toolbar.
 * Upload this program to the arduino.
 * Connect the arduino to the ESC and a poteniometer. You may need a breadboard to properly do so.
 * The White Red and Black wire triplet on the ESC:
 * Red is connected to the "Vin" or "5V" terminal. Vin is recommended because it uses a higher voltage when a 9v power supply is hooked up the the arduino. The 9v power supply in addition to the USB cable link is recommended for the arduino
 * Black is connected to the Ground
 * White is connected to the ~9 Digital pin
 * The Poteniometer. I used a 2k ohm, it is recommended, but it may not matter. There should be three pins.
 * Left most goes to arduino ground.
 * Middle is connected to A0, the analog in. (the analog in you use may not matter)
 * Right most is connected to The Vin or 5v supply. (The vin or 5v also may not matter which you use)
 * With all this hooked up, open the serial monitor with the arduino on
 * Vary the poteniometer so the serial value is zero, then vary it and note where the value of 250 is. Do not exceed the value of 250. Return to the zero value, it should be an extreme of the poteniometer.
 * Plug the power supply into the ESC Main leads. I used 12v positive to red, and ground to black on the black and red pair of 14 gauge wires.
 * Once connected you should here a single beep. If you do not, recheck you setup, and then troubleshoot.
 * If you hear the beep, the motor is ready for operation and increase the serial value to increase speed.
 * You should hear a double beep before the motor starts

Pictures:

My Third task

 * Improve ESC reliability, get it to function without either computer or poteniometer
 * Get tutorial up/updated

Summary of actual work over third weekend

 * Simplified the Setup
 * Attempted to get the Arduino to Run the ESC without the computer, to no success.

Week3 Narrative
The Set-up was simplified to that used on the ESC tutorial page.
 * Pin 9 goes to control wire (thin white)
 * 5v (or Vin) goes to leftmost potentiometer terminal, Analog 0 (A0) goes to Middle poten. terminal, and the last poten. terminal goes to ground (otherwise the values don't read correctly).
 * Power supply ground goes to black battery terminal (this wire hooked up first), +12v goes to thick red wire (this must be hooked up second, before control wire).

Through Experimentation, Using a 5v USB supply, a 9v supply, and a PC USB port, The Uno only correctly ran the sketch and modulated the ESC with the Computer Connected. Several options were tried to solve this:
 * Take out the code in the sketch that communicates the digital pin 9 output, so the Arduino won't wait for a possible reply by the computer
 * As per the Arduino Troubleshooting website, tried connecting the RX and TX pins together, to prevent unwanted chatter. This did not work either. I also did not have a 10k ohm resistor to put the RX pin to ground, which is another option to try.

The next options are to use some advice from the troubleshooting page to somehow stop sending serial port information to the board, so it starts up and runs the program correctly. A work around to test this would be to power the ardiuno up (so that it works) with the PC, then seamlessly transfer power to an external source. Also attempt to diagnose the arduino, by monitoring what comes out of pin 9 while it is not connected to the PC.

Also:
 * Counterclockwise on the Poteniometer is "off" or it decreases speed/pulse length from pin 9.
 * Clockwise is "on" on the Poteniometer, or it increases speed/pulse length from pin 9

My Fourth task
Use the proper tools to get the Arduino to run without a computer. Then, use power from the ESC to power the Arduino, so nothing but the main power-supply, ESC & motor, and Arduino (plus wires to connect) are needed to run the motor.

Summary of actual work over fourth weekend
Got Arduino to run off of 5v Power from ESC, correctly modulated ESC, and varied fan speed.

Did some updates on Tutorial: ESC Programming added Hextronik Section and Step by Step

Last Tasks to Complete:
 * Re-enter programming mode on the ESC to get it to stop premature shutdown, as it now does (need to enter programming mode?)
 * See if ESC will hook up to Arduino with though Pin set on board, no wires needed.

Week4 Narrative
Through exerimentation, I determined that the external power supply I was attempting to get the Arduino to run off of was causing it to generate a "dirty" or "noisy" signal for the digital output from the Pin 9 socket, most likely because the supply was not grounded properly. This was fixed by using the 5v supply from the computer Power supply, and then using the ESC's 5v from the red wire in the "control wire" bundle.

The Dirty Signal from the Arduino, using the bad 9v power supply

The Clean Signal from the Arduino, using power from a USB computer port.

The result from using these power supplies is increased simplicity in connecting wires and running the ESC.

Running off the Converted Computer Power Supply:

The Final Set up:

The Wire Set up with a few instructions:

 * ESC "Control" Bundle:
 * Red (Power Cable)-> Plugs into Vin pin socket on arduino
 * Black (Ground) -> Plug into any ground pin socket on arduino
 * White (Control) -> Plugs into Digital Pin 9 Socket on arduino (or whichever pin was assigned to PWM on program)
 * Poteniometer (terminals pointing away/up):
 * Leftmost Terminal -> 5v supply Pin socket on Arduino
 * Middle Terminal -> Analog 0 input pin socket (A0) on Arduino
 * Rightmost Terminal -> any ground pin socket on Arduino (This is important)

 * Not Shown in Above Picture, but essential and Should be Hooked up First
 * Ground wire (first to be hooked up) From ESC negative battery terminal (thick black wire) to ground on power supply
 * 12v Supply (Second to be hooked up) From ESC positive battery terminal (thick red wire) to 12v on power supply

The motor appears to shut down prematurely, before it is up to full operating speed, blinking its red light (indicating a fault). During experimentation with the power supplies, the ESC appeared to enter into programming mode while the dirty signal was being broadcast. It would beep four times fast then 5-7 times slowly, And I wonder if a default setting is shutting it down before it draws more than 8 amps, as it drew 9 amps at full throttle.

Talk:Controversies in Science/Are humans causing global warming/A Critique of Global warming and long term climatic changes: a progress report.

CO2 must be causing some form of pollution as it is the biggest contribution humans are releasing into the atmosphere. There has to be a reason why global warming is happening. LaurenAL (talk) 18:54, 16 March 2012 (UTC)

 * Humans may not be completely to blame but they are definitely contributing. CFC's are proven to contribute to global warming and have already been banned. We (humans) are still producing N2O and N2O, once it reaches the stratosphere, releases ozone depleting chemicals. The human population still needs to reduce the amount of damage we are doing considering that the earth naturally contributes to this as well. --Randana (talk) 00:19, 11 April 2012 (UTC)

Nuclear power greener/A Critique of Nuclear power the problems

(Review Paper) Cited in

Nuclear Power Would Not Stop Climate Change
An analysis of the possible repercussions concerning the government's decision to build a new plant is outlined. The areas discussed are: climate change, energy, security, radioactive waste, terrorism, safety, reprocessing and nuclear proliferation and costs of building the plant.

New nuclear power stations would not stop climate change. With only 10 proposed reactors by 2024, there would only be a 4% decrease in carbon emissions which as this article states, far too little, far too late.

If we were to build ten new reactors the amount of highly radioactive waste would triple. There is still no safe disposal method for radioactive waste, which can remain dangerous for up to a million years, and improper disposal can lead to contaminated water supplies.

Methods
There has been a strong financial analysis of the growth of the nuclear power industry. The analysis includes the amount of money that was used to create the nuclear power plant infrastructure and the amount of time spent on building it. They also investigated the disposal method of the nuclear power plants waste and the negative effects on the environment where greater then other forms of energy. This was then bench marked on the amount of renewable resources that cannot be developed due to the investment in nuclear power. .

Results
This article discusses that building nuclear plants can have negative results on the environment. Not only will it costly (upwards of 200 billion Euro’s), it also increases the changes of terrorist attacks, it is dangerous to dispose of, and the effects of climate change are very insignificant. In addition, the proposed new infrastructure of 10 new reactors is not only costly, but it also takes a long time to complete therefore rendering the development inefficient. The energy supply that the nuclear reactor produces does not assist with the growing need for hot water and central heating. Nuclear power only produces electricity which limits the use of the product. .

Engineering Projects/FanWing/Howard Community College/Spring 2012/689 Aeroxperts

Problem Statement
The goal was to build an aircraft using the fanwing concept.This aircraft has a cross-flow fan along the span of each wing. The fan pulls the air in at the front and then expels it over the wing's trailing edge. In transferring the work of the engine to the rotor, which spans the whole wing, the FanWing accelerates a large volume of air and achieves unusually high lift-efficiency.

Team Members
Inh117

Sali6089

deakin2074

Summary
Week 0: We mostly did Brain storming and were coming up with different ways of making the squirrel cage or the cross-flow fan of the aircraft. The cross-flow fan is basically the heart of this project.

Week 1: We drew up several designs and understood how the concept of how the fanwing works.This documentationFanWing made us understand of how the cross flow works.

Week 2: Different ideas came from everyone in the team. For the cross-flow fan, Dan came up with the idea of using window blinds, which would go through a hamster roller, but Syed's idea wasn't going to work because the hamster roller would be pretty heavy and big for the aircraft, so Ian came up with the idea of using CD's and putting the blind folds through them.Ian also created 3D design of the aircraft.

Week 3: Syed bought all the materials that we needed for the project.

Week 4: The construction of the cross-flow fan began.

Here are a few photos while working on the project

Story
This project is a big project. A lot of brainstorming is required in order to start off this project. The heart of this project is the cross-flow fan or squirrel cage, once that's done the rest is not that hard to finish off.The goal of this project is to create an aircraft using the fanwing concept. Fanwing aircraft has a cross-flow fan along the span of each wing. The fan pulls the air in at the front and then expels it over the wing's trailing edge. In transferring the work of the engine to the rotor, which spans the whole wing, the FanWing accelerates a large volume of air and achieves unusually high lift-efficiency.

Week 0, was all about brainstorming, different ideas came from everyone in the team. By week 1 everyone had an idea of how a Fanwing works, this documentation FanWing gave us a clear picture of how a Fanwing works and during week 1 Ian basically summarized all the info that was in that documentation. By week 2, everybody came with different ideas of how the cross flow will look like, Dan came up with the idea of using window blinds, the window blinds idea was great and was agreed upon everyone in the team. The window blinds have a design that would work great as fan, and would also provide a greater upthrust. Syed came up with the idea of using a small hamster wheel that would have linear holes in them in order for the blind folds to go in them, but his idea wouldn't have worked because hamster wheels are heavy and embedding them on the aircraft would have damaged the entire aircraft. So, Ian came up with the idea of using CD's instead, the CD idea was great, and was also agreed by everyone in the team. The good thing about the CDs is that the CDs spin at a very high revolution if they are attached to a generator. By week 3, during spring break, Syed gathered all the materials that we needed for this project and those materials which was agreed upon by everyone in the team. By week 4 construction of the cross-flow began. several thin pieces of wood, which were 48 cm in length were cut in half and were attached to the CD's. In the CD's, drill holes were made around the CD's and each hole had to be a less than a cm apart from each other. After attaching the thin pieces of wood to the CD's, window blinds were glued around the thin pieces of wood. By the end of week 4 1/3rd of the cross flow was done.

Decision List
The window blinds idea was agreed upon by everyone in the team. Window blinds have a design that would be great in helping the plane creating an upthrust. The CD idea was also agreed upon by everyone in the team. Attaching a generator to the CD's would result in greater revolutions per second that would result in greater upthrust as well.

Material List
Materials that were needed outside of the engineering lab.Here is the list of the materials that we used for this project:

1 Window blinds, 32 in Wide and 64 in length, $4.65

2 15 thin pieces of wood,48 cm in length and less than a cm in diameter, 76 cents each

3 CD's, 10 pieces pack, $5.89

Materials which were used from the Engineering lab

4 Mikita Drilling machine

5 clamp

6 seesaw

7 scissors

8 hot glue gun

9 100 cm ruler

10 Markers and pens

The cost of the materials was approximately $11.50

Software List
SolidWorks 2010 CAD software was used to create the initial soft designs used to construct the Fanwing. We used PowerPoint 2007 for our poster. The interface provided is simple and intuitive to navigate an easily edited as it is a software package specifically for creating presentations using images and text boxes.

Time
We worked 21 hrs on this project.

Tutorials
This documentation and video really helped us understand how the project works:

Understanding the concept of FanWing and how it works

FanWing

Next Steps
On this team pg we made 1/3rd of the crossflow fan, which is 25 cm in length, so the next steps is to make a 50-75 cm of the cross flow, but before we start building that we need to test to see whether 25 cm cross flow works or not by using a generator and identify any errors, once we do that we need to build the body of the aircraft and the 50-75 cm cross flow I.e. if there are no errors.

| Coanda Effect II

Write problem/project Goal
To learn how to manipulate the Coanda effect such that static ojbects are able to gain lift and/or momentum.

Launch of Project #2
I am drafing designs of possible blades that will be tested in the second project: manipulating the Coanda effect to create an airfraft that is dependent on three types of blades - a turbine blade, a fan blade, and a simple flowblade. Each blade will be powered by an alternative powersource. .

Summary of actual work over second weekend
I began to proceed in the construction of the final design. There were several problems which I encountered; one of them was the fact that I was using duct tape in order to create the blades for the slotwing as well as creating too many slots in the tubing. Both of which may compromise testing in that air may not be able to flow freely around the form of the tube, because of the obstuction of tape.

Closure to Project #1
In order to bring closure to the first part of the Spring 2012 Coanda project, I am finally constructing the bits and peices of the Coanda vehicle. It has taken a considerably long time to achieve progress at this point, but completion (as well as trial and error testing) is projected to be within two weeks, or four class meetings from today (3/22).

So far, I was able to form the slotted tubes, which I accomplished by taking specific and accurate measurements and using pink tape to guide the areas which I wanted cut our of the tubes. In order to gain a precise measurement of the length of the tubing I had to use a straightedge, document the total length of the tubing and placed pink tape along the narrow field of which I intended to make the incisions. (see figure #1)

First, I knew that this one large tubing with preliminary markers had to be cut in half. It was very imperative that I made the incisions in the tubing along the respected measurements and influence lines so the the tube is not bent of crushed the process of constructing the design. At first, there was a minor mismeasurement in the lengths of the two tubes, so I quickly dealt with that by using the buzzsaw to shed the extra 4-5 mm. from the end of the tube. I used a buzzsaw in order to cut out the very thin slots on the tube.

After I completed the construction of the tubings, I began to work on the wheeled platform. I found a peice of cut wooden board, and began to make lines of influecne on them because I wanted to affix roller wheels to the bottom of the board. Due to previous experiences making wheeled platforms, I learned that if the wheels are not aligned with eachother, the platform of which you are affixing them will not move, or will move with resistance. So, it took careful measurement with a straightedge to mark exactly where the wheels are most appropriate to be on the platform. The completed design is shown above, however, in the process of constructing the platform, it was very helpful to use the pink tape in marking approriate spots.

Instead of naling the wheels to the bottom of the wood, I used Epoxy Resin, a strong glue used for wood materials, to affix them to the platform. It took a while because Epoxy Resin takes a long time to dry; however, I tended to expidite this process by duct taping the wheels down around all sides so that the glue between the platform and the wheels are able to dry. Below is a snapsot of the bottom of the platform without the influence lines. When the wheels were fully dried, I decided to test the platform. It worked smoothly. At this point there is the welding of the angular blades which I will be used to direct the flow of air out of the tubes. Since I was not privy to the fact that "soldering" is made for electronics and wiring purposes, multiple solutions to getting the blades constructed are 1) taking the blades to Lowe's and having them welded and 2) having them bent with a bending machine. I believe that it would behoove me more to take the blades to Lowe's to have them professionally welded according to my sketches. It would be prudent to try and have them bent, and the metal warps, and can't fulfill its function

I was able to bend the metal blades. I used the clamping machine to cold together the edges of the blades, and bent them fowards as much as possible until a "curve" was achieved. When I got around to testing the effeciency of the curved blades, they apparently worked very wil in manipulating air flow around the tube. This video, a string was able to almost curve wholly around the form of the tube. From this testing, it can be concluded that the dynamic flow of air is sufficient; now there is the problem with the power supply. The power supply is not strong enough to emit a force full stream of air, so were are launching a second testing trial. I believe that since the air pump was not powerful enough, even at maximum voltage (12 volts, because the volt standard on the air pump was 6 volts), there needs to be efficient, alternate wind supply that will create a stronger flow of air. We found two smaller fans that would be ideal for producing a strong enough current of air. Adam is going to hook up these small fans (perhaps CPU fans; look on Adam's page for photos) to electric power supplies and test them for wind force; in the mean time, I tested the voltage extent of the inflatable air bed pump, and determined that it could be powered at a maximum 12 volts without overheating and breaking; that alone wasn't even enough to produce an appropriate air flow.

My Third task
Find a suitable power supply for the tail rotor demonstration model. Begin modeling and drafing for third design. We are scrapping our plans for Coanda Project #2 aka "best wing testing" because this Coanda fan project (Project #3) seems much more promising.

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

Week3 Narrative
Throughout spring break, I was unable to complete the remainider of project two because of the lack of strength in the wheeled platform in support of the slotwing tube and air pump. No matter how I attempted to set up the platform, either through a constructed cardboard platform or a block of wood, the entire platform still fall apart even after drying. Secondly, the cardboard stand did not support both slot tubes on the platform. Unfortunately, the Coanda project will not be able to demonstrate the movement of a wheeled platform down a specific path (for now) because I am not able to keep the platform assembled in one price; however, I will able to refocus the second project as a means to demonstrating how the Coanda effect can be used as a vacuum cell of some sort; to be able to pick up objects from a static state.

I really didn't want to give up on this part of the project; however, the tediousness creating the platform took time and trial.

Here were the issues that I encountered that didn't make the project successful as I wanted it to...
 * Epoxy resin sucks. It is too sippery and can not support large weights. I even brought it from the hardware store!
 * The weight of the slotwing tube was too great; but somehow, I managed to counterbalace the weight by taping the air pump to the opposite end of the tube. It worked, but the weak platform, made by the slippery Epoxy resin, made it difficult to mount it. I used more duct tape.

So what am I going to do? I am going to spend my last week evaluating what I can do to conduct the experiments that way I wanted them to be tested, but I will still provide proof of the use of a Coanda tube in the movement of particles from a static state.

Conception of Project #3
While I was watching more Coanda related videos so that the project is more inventive for future students, I happened to stumbled across this video. (Note that in this video, the fan unitilizes a suction pump in the base of the fan that attracts air into its annulus, then ejects it back out by blowing it along the design of the annalus. I was so impressed with the fact that suction is being used in the manipulation of air flow in the Dyson Air Multiplier, just as the inflatable bed air pumps utilize suction, that I created a sketch that can reverse engineer the bed pumps and use the suction mechanism to try and CREATE a power supply through wind force, a la the goals of the wind turbine project. With the little bit of sheet metal, I might be able to make a small scale replica of the Dyson fan, but with a less complex design than the annulus (ring shape).  Below is a possible sketch of what a final design may look like if we continue to pursue this project.

My Fourth task
I am going to futher my plans for project #3 by taking the last bit of sheet metal bending it to the form described in the Dyson air fan, and hooking it up to the air pump, as described in my notebook design. What I hope to achieve is similar to the slot wing; the only difference is that the device will be a mere fan that uses a reverse engineering air pump in order to create a sharp jet fan.

Summary of actual work over fourth weekend
Over the fourth week, I decided that there is nothing more I could possibly do in demonstration of the effect. I plan to move on to another project. I am going to document all of the possible ideas and possibillities for inventions in regards to the Coanda effect, such that future ENES 100 students will be able to emulate to utilize the principles for future pursuit of this project. I, however, and going to be thorough and complete my recreation of the Dyson Air Multiplier.

Week4 Narrative
In efforts to try and wrap up my final coanda project, I began construction of a metal peice that will be bent into a circular frame, such that the mechanic of the Dyson Air Multiplier could be emulated. As before, I am going to use aluminum sheet metal in order to manipulate the physical form of the Air Multiplier, such that the Coanda effect is demonstrated, and the total output of air is increased.

 * Note that this the same aluminum sheet metal used in the construction of the angular blades in the first Coanda project.

Write problem/project Goal
The goal of the fanwing project is to build a model aircraft using the fanwing concept

My First Task
Mostly brainstorming and looking at various videos on youtube.I don't know really know much about fanwings.Understanding the concept of FanWing This video though has helped me a lot and has given a better understanding of how fanwing works.

Summary of actual work over first weekend
This week was mostly done according to plan. I was basically trying to understand the concept of the FanWing on how it works and what's it used for. I basically brainstormed literally for 2 hrs on how to make this project into a success. I watched various Youtube videos, but the one video which really made understand the concept was this one Understanding the concept of FanWing and how it works. I'm hoping that this project is finished within the 3 week frame that we have.

Week1 Narrative
Before I started off on this project, My aunt threw a party in her house, and I had to attend (I know that this is completely irrelevant). So, while I was at her house, I saw a heater which had a roller spinning around. That roller made me think that kind of a roller could be used for our project. The structure of the roller was kind of like this How the roller looked like. Since I didn't know the product's name I was sort of unfortunate in finding out which company made those rollers. But the roller really did look like the design above. I discussed about this with my team mates over the week and they said that it is not going to work, since the rollers of the heater are pretty heavy and large and won't be able to lift the plane, since the plane is going to be made out off wood. After that I started looking for other materials that would look like the roller as it was shown in the video. I did find a printer which had a roller inside, but it was way to small for our project and other printers did not have a roller in them. I tried to search it for hrs, but I couldn't find any. After that I just gave up, and started looking for generators, because we needed a generator that hooked up to a battery and the 'generator would help in rolling the roller. We did find a black DC generator, but unfortunately there wasn't any more of them, also it didn't produce any current or voltage. The next day, I had to present the progress of our project to a panel of audience. One person in the audience gave us the idea of using a long hamster cage, the thing on which the hamster runs, and basically use that for our roller. That idea is actually pretty great since it is light weight and will help the plane with greater upthrust, so I am looking forward to talk about this with my team leader. My client also said that we don't need a generator for this project since that we will be using a 11 volt battery. But I don't think that will work, since the battery will be connected to the generator and the generator will produce power in order for the roller cage to move. I still have to discuss about that with my team leader.

My Second Task
My 2nd task is to basically decide with my team leader whether to use the hamster cage or not also whether to use a generator for this project or not. After me and my team have to start working on the design stage because a lot of work still needs to be done. Next week will be all about designing it.

Summary of actual work over second weekend
This week as I mentioned before was basically buying a hamster cage that was supposedly 1.5 meters in length, also this week I was really interested in finally designing the roller blades, so after the spring break we could finally start working on the body of the plane, but unfortunately neither of the 2 were possible. Hopefully over the spring break I will finish designing the roller blades.

Week2 Narrative
This week I was given the task of buying a hamster wheel that was supposedly 1.5 meters in length, so I went to petsco with one of my friends to look for it, they did have an hamster wheel that was 20 cm in length and had the same diameter as the CD but that was still way to small for our project. Several of those would have been great since they weren't as heavy and would have worked perfect on our project. The only thing was that it was expensive, one of those costed around $10,so it would have been worthless if almost $40 were spent on it and our project didn't work and my team leader also discouraged me from buying it since it is still going to be heavy.

My Third task
My next task, actually is to start building the rollers. Over the spring break me and one of my team mate will work on making the roller. If not then during week 3 the roller will be made, that week we also try to make the wings of the plane.

Week3 Activities
No Engineering work was done on week 3. I intended to do something over the spring break but wasn't able to because my team mate had to go to WWII study abroad trip and I had to go to Virginia due to an emergency.I, however, did do some brain storming and decided not to put the thin wood pieces on the center of the CD instead make holes on it and put the thin piece of wood in the holes and stick smaller pieces of window blinds on it.Putting the small thin pieces of wood through the middle hole of the cd would have damaged our entire project.

Summary of actual work over fourth weekend
Well over the break I originally intended to work on the roller or the squirrel cage but wasn't able to because of the reasons stated in week 3. However, after the break I did manage to gather all the materials that we needed for the project and I and my team mate finally made one part of the roller that was approximately 25 cm in length. Our goal is to make the roller that at least 75 cm and embed it on the body of the aircraft. Hopefully in the next 2 weeks or so of project 3 the project would be finished.

Week4 Narrative
After coming back from the break, I started working on the cross flow fan. We were really behind on our project. I bought several thin pieces of wood that were 48 cm in length and were approximately less than a cm in diameter they were very thin and putting them through the center of the cd's would have damaged our entire effort on the project. So my team mate came up with the idea of using those thin pieces of wood and drilling small holes around the cd's and putting them through the small holes of the CD and then cutting smaller pieces of window blinds and sticking it to the thin piece of wood with the wood connected to the CD. This idea actually came to me before during the spring break but I sill wanted to confirm it whether it would work or not. So, I started cutting the 48 cm thin piece of wood using a see saw, and i cut it in half, after that I and my team mate took several CD's each and made lines through them, lines had to be parallel to each other, and then I made a small dot on the CD in order to make holes through the CD, I was really nervous while I was drilling holes through the CD's because I thought I might crack the CD. Once the holes were made and the thin pieces of wood cut in half I just had to place them through the CD's, once they were placed through the CD, we just measured the distance between one CD and the next and result came out to be 5.5 cm in length. So, then I measured the length of the window blinds, the length was approximately 22 cm,I measured 5.5 cm of the window blinds and got at least 4 small pieces of the wind blinds, after that my team mate and I started gluing it on the thin piece of wood. We made one part roller that is approximately 25 cm, our goal is to make a 50 cm to 75cm roller.
