Corn Starch Problem Statement
Experiment with the non-Newtonian fluid, corn starch, and show how this fluid holds unique properties.

Team Members

 * Baminnick
 * Alex
 * Z. Hill
 * Epcole

Summary
The first week of this project was spent individually, but we completed the same experiment. The experiment was to develop the cornstarch mixture and determine its properties. The second week of this project was spent individually, and each team member completed different tasks. The tasks that were completed were developing a large quantity of cornstarch, experimenting with ferro fluid, and create a response in the cornstarch using sound vibrations. The last two weeks were spent on developing a ferro fluid, and determining why cornstarch's properties are so unique. During these weeks, the information determined from the first two weeks was used to branch off and explain non-Newtonain fluids.

Poster
A few of the project photos that were taken are distrubeted on the right side of this wiki page.

Here is a list of cornstarch youtube videos that were devloped by us:
 * Non-Newtonian Fluid Cornstarch
 * Mini Monsters
 * Monster Cornstarch Video
 * Difficulty with Stirring Cornstarch
 * Pushing and Pulling Cornstarch Vertically
 * Forming a Ball with Cornstarch
 * Tearing Cornstarch
 * Stomping on Cornstarch
 * Rolling Cornstarch
 * Viscosity Experiment
 * Ferro Fluid Experiment

Story
The first week of the project was spent on producing the cornstarch mixture and experimenting with it. The only problems that occured during this week were collecting the materials for the cornstarch, however this was solved by visiting a grocery store and purchasing cornstarch. The experiment produced different videos which were explaining a few of the properties of a non-Newtonian fluid.

The next week was spent more individually than as a team, we each split up and performed three different experiements: 1. Cornstarch in a large quantity, 2. Producing cornstarch monsters using sound vibrations, and 3. Using an ultrasonic horn on cornstarch. The problems in the 1st experiment were purchasing the large amounts of cornstarch and producing the mixture. By going to BJ's, large amounts of cornstarch could be purchased. To solve the stirring issue, a pattern was formed so the cornstarch mixture could be produced quickly. The problem in the 2nd experiment was producing large enough sound vibrations. Using an amplifer and a wider speaker cone produced the proper cornstarch monsters. With each of these experiments, more properties of cornstarch evolved resulting in further documentation of a non-Newtonian fluid's properties.

The last two weeks on this project were spent completeing two large experiments. One of which was explaining the properties of cornstarch with a viscosity experiment, and the other was developing ferro fluid to document that fluids properties. Regarding the viscosity experiment, the first part was researching how to measure viscosity and how to quantitatively determine it. It was determined that viscosity is the shear stress of a fluid divided by the strain rate. This information resulted in an experiment in which the shear strain and strain rate were measured. However, the results of the experiment showed large error due to the lack of control in the system. Thus it was concluded a more controlled environment was need, however the next team can continue this experiment and learn from these errors. In the ferro fluid experiment, many of the problems that occured were a result of not properly producing the fluid at first. After some mis-steps in creating the ferro fluid, MICR toner was ordered off the internet and ferro fluid was successfully created. There were a few problems with the fluid itself as it didn't produce the magnetic field's spikes as seen in the example video. The correct ratio would probably needed to be used, as the fluid created did not quite have the right ratio. The ink could have had some defects to it, or may not have been as magnetic as other inks. The magnet, while a rare earth magnet, could have been bigger to show a proper magnetic field. There were plenty of problems to solve for groups going forward.

In summation the first two weeks of this project were spent on documenting the properties of the cornstarch mixture. The last two weeks were spent on using this information to explain these properties with a quantitative value. Although this project was not completed to its full potential, a future team can continue this project with ease due to the documentation.

Decision List
Here is a list of the formal decisions we decided upon as a team:
 * 1. Collect cornstarch materials and prepare non-Newtonian fluid cornstarch.
 * 2. Experiment with the non-Newtonian fluid and determine its unique properties.
 * 3. Record results of experiment.
 * 4. Prepare the sound cone to produce vibrations.
 * 5. Place cornstarch on the sound cone and show more unique properties of this fluid.
 * 6. Record results of experiment.
 * 7. Develop a large quantity of cornstarch.
 * 8. Use this large amount of cornstarch to explain further properties.
 * 9. Record results of experiment.
 * 10. Prepare a shear stress experiment set up and procedure to quantitatively explain the properties of cornstarch.
 * 11. Measure the shear stress and strain rate of a non-Newtonian fluid (cornstarch) and a Newtonian fluid (water).
 * 12. Record results of experiment, and interpret data for complete analysis of non-Newtonian fluids.
 * 13. Collect necessary materials and develop a ferro fluid mixture.
 * 14. Experiment with the ferro fluid.
 * 15. Record results of experiment.

Material List
Here is a list of materials that were used to complete this project:
 * Sound Cone, to produce vibrations
 * Corn Starch, a component of the non-Newtonian fluid being studied
 * Water, a component of the non-Newtonian fluid being studied
 * Saran Wrap, to maintain a clean speaker while experimenting with the corn starch.
 * Various Measuring Cups, for measuring the amount of water or cornstarch used in the non-Newtonian fluid.
 * Stirring Rod, for stirring or mixing the cornstarch and water materials.
 * Container, to store cornstarch when experimenting.
 * Trough, contains a fluid so the shear stress and strain rate can be calculated.
 * Force Probe, a tool used to measure the force applied of the shear stress.
 * Stopwatch, a tool used to measure the velocity of the strain rate.
 * MICR Toner, to produce the ferro fluid mixture.
 * Vegetable Oil, to clump together the MICR toner.

Software List
Here is a list of software used to complete this project:
 * NCH Tone Generator
 * Microsoft Excel
 * Vernier Force Probe

Time
As a team, we spent two hours in class and four hours outside of class every week on average. Seperately, each individual member spent about six hours every week. So in four weeks, the team spent eight hours together. And individually, each team member spent about sixteen hours in four weeks. Therefore the total time spent on this project is seventy to eighty hours.

Tutorials
Here is a list of youtube videos of the various properties of corn starch as a non-newtonian fluid:
 * Monster Video #1
 * Monster Video #2
 * Faraday Waves
 * FerroFluid
 * Corn Starch Pool
 * Corn Starch Walk in Slow Motion
 * Ferro fluid recipe

Here is a list of links to information about non-newtonian fluids:
 * QuickSand
 * Oobleck Recipe
 * Introduction to Viscosity, Shear Rate, and Shear Stress
 * Dilatant or Shear Thicking Fluid
 * Fluid Mechanics

Next Steps
Using the videos and photos as a guide the next team should redevelop these experiments to explain the properties of cornstarch. Then using this information the team should continue where we left off with the ferro fluid and viscosity experiment. It these two projects are completed then the next team should redo all experiemtns but with a different non-Newtonian fluid, such as ketchup of syrup.

Task one was not decided on, I was supposed to meet with a group member on Friday, but due to a miscommunication and a last minute appointment, I was unable to. So the project was stalled for the weekend.

Compare actual work done to Task2
As no real work was done on the first week, the differences where no work was done over the weekend was minimal.

Week1 Narrative
Week one was about getting the speakers to work. getting the speakers to work was really the first step to this project, the speakers had to work to get the waves in the fluid and the monsters to form. We brainstormed and tried to wire the headphone jack to one of the speakers to see if it would work. I noticed that the speaker had a wire on the inside was disconnected and wouldn't work. We then tried a few other speakers, wiring the speakers to the jack to the computer to test to see if they were working. They didn't work. On Wednesday in class we tried again, and were repeating our mistakes since we are all pretty new at wiring speakers, when Professor Forester told us about the wave generator and the wire to it and voila! The speakers worked. I then played around with the wave generator box to find the proper waves and frequencies needed to create low sounds with plenty of vibrations. Sine waves and 10Mhz work really well.

Task two was to create ferro fluid out of printer ink and vegetable oil.

Week3 Narrative
I got the ink cartridge that the employee at Office Depot said contained Micr (the magnetic ink needed to create ferro fluid) but after some trial and error, the ferro fluid didn't form. After doing further research on the ink, I found out that it didn't contain any Micr after all. I then decided to order toner from the internet and it should arrive by Monday.

In this week I didn't get to do the equation, but I made a successful ferro fluid batch.

Week4 Narrative
After waiting for the correct MICR toner to arrive, I was able to successful create ferro fluid, although to a lesser degree than some of the videos online. My ferro fluid reacted, which was an improvement over the previous week, but only formed small blobs and not spikes like the videos showed. I believe this was due to the ratio of iron to ink in the MICR powder, the size of the magnets used to react the solution, and the ratio of vegetable oil to MICR toner.

My top three project preferences were Perfume, Corn Starch, and Music project, and I was assign to work on Corn starch..

Write problem statement
One of my research interests is the behavior of corn starch gels. Corn starch has interesting properties that I will try to find out why it act like this.

Assign Task1
task one for the week one to get the corn starch, and make an oobleck mixture, and find the recipe.

Compare actual work done to Task2
The Major task was done completely, I was able to get corn starch, and found how it acts when you mix it with water, it became solid and liquid.

Week1 Narrative
The starch made from the endosperm of corn, containing amylose and amylopectin starch molecules. When starch is heated in water it forms a viscous, opaque paste. The paste forms semisolid gels upon cooling and has the ability to form strong adhesive films when spread and dried. Cornstarch is not freeze-thaw stable and is used widely except when clarity or the lack of gel formation is required. It exists as fine or course powders. The coarse starch is sometimes termed pearl starch. It is used in sauces, puddings. pie fillings. and salad dressings. the typical usage level is 1 to 5 percent. It is also termed common, regular or unmodified cornstarch.

One of the most important thing was made this week was how to get the perfect recipe for the corn starch to act like solid and liquid.

At first, I got the corn starch, and because I was very excited I ended up opening the box from the bottom. After getting my materials ready, I followed the link that had the main recipe..:recipe of Corn Starch, I followed step by step and I had some issues, my first problem was less water, and I add more water and waited about 10 minute and start stirring again.The mixture was acting like glue or honey most likely and that is how it spouse to be like. After adding more corn starch and waiting little more, nothing much happen it was not as sticky as it should have been. I have decided to add more corn starch to the mixture, and find out how it is going to act, if it acts like a solid I would add more water. I finally reached my goal, it was acting as a solid and a liquid.

This part of the project was not difficult but it just needed some preciseness and accuracy by adding water and corn starch to find the perfect amount for corn starch to act like its states (solid and liquid) To see how corn Starch act, in a very short video just follow the link. The Mixture of corn starch

Things that You need to make the mixture
 * 1)Cornstarch
 * 2)Pitcher of water
 * 3)Measuring cups
 * 4)Mixing spoon
 * 5)Newspaper for covering tables
 * 6)Food coloring or tempera paint (for fun)if you want...

My task will be putting the corn starch into the speaker cone and use the vibration, to create some monsters. And perhaps before that to determine how to connect the stereo to the laptop.

Compare actual work done to Task2
In week two, I have successfully connect the stereo to the laptop and created the corn starch monsters inside the speaker's cone.

Week2 Narrative

 * NCH tone generator.jpg
 * Food color in corn starch.jpg
 * Speaker that have been for the task.jpg
 * The whole set up.jpg

In this week task, I have accomplished a massive part of the project, I have actually ,connected my laptop to the stereo, and controlled the audio system by using the software called NCH tine generator. and most importantly I have created corn starch monsters inside the speaker's cone

My first goal was to connect the speakers to the stereo and to see if they are worth working for. That was not very difficult task, it was simply connecting wires into the right place at the back of the stereo and back of the speakers. My next step was to connect all stereo to the laptop that could allow us me to control the frequency with the amplifier. I have tried using all sort of cables but it did not work. I made some research about how to hook your stereo to your PC/laptop on Google and I have found a great website that explain everything smoothly step by step just click the link for more information how to hook up your stereo to your PC I got an RCA (Radio Corporation of America) cable connector and follow the steps but still did not work, some issues occurred. There are for tune section on the stereo, : 1)CD mode : 2) AM/FM mode : 3) Tape mode : 4) VCR mode. I thought, it should be on the AM/FM mode because it is using the radio signals, but I was wrong, it was the VCR mode. After a long time I have determined that it is the VCR mode that I have to keep the stereo in in order to make the connection work properly.

Lastly, I made a the mixture of corn starch and add some green food color just for the fun of it. Poured the corn starch into the speaker cone, and turn the volume on very gently, and watching how the corn starch behave. As I was increasing the volume, I could see that vibration gets stronger and stronger at the full blast it was trowing the cornstarch everywhere. This week task very fascinating I have recorded most important parts and add some pictures as you could see it here in Wikiversity entry just click to the video links here.

Compare actual work done to Task2
I have purchased pigmented black ink and tried in my experiment this week, but after adding the vegetable oil and mixing it, I have poured the mixed ink and oil onto the metal flat surface.. and I did not work.

Week3 Narrative
material I have used in my experiment as follows
 * 1. regular ink for printing
 * 2. a clear cup to mix
 * 3. sheet of metal tray
 * 4. chopstick
 * 5. gloves
 * 6. magnets

the video of regular ink for ferrofluid

In this week task, I have decided to work on ferromagnetic fluid by using the ink and mix it with vegetable oil to create some unusual behavior of an compound. At first after getting the ink, I wanted to use a very small amount of the ink and add a little bit of vegetable oil. I poured in a clear cup as you can see on the pictures about 5ml ink and 3 ml vegetable oil. and I started to mix the mixture with a chopstick, and let it sit a little bit.. Then I put my gloves on and to make sure that I don't color myself with ink mainly to not make a mess. I put the metal flat on my desk and pour a little bit and start moving the magnet from underneath around. The problem occurred, there were no movement of ink inside the metal tray.

my solution was to pour more ink inside the metal tray and start over again, and I did that, the result was the same. Then my second solution was to add more vegetable oil and tried again nothing happened. I wanted to make some research and to determine about how to make the ferrofluid mixtures ready.. I have found the website at this link [the link how to make ferrofluid] and found that the ink I am using is wrong ink, I needed to use the magnetic ink to compelete this task..

I wanted to add here for some people who may not have heard what is ferrofluid, what does it do? A liquid magnet or ferrofluid is a colloidal mixture of magnetic particles (~10 nm in diameter) in a liquid carrier. The carrier contains a surfactant to prevent the particles from sticking together. Ferrofluids can be suspended in water or in an organic fluid. A typical ferrofluid is about 5% magnetic solids, 10% surfactant, and 85% carrier, by volume. One type of ferrofluid you can make uses magnetite for the magnetic particles, oleic acid as the surfactant, and kerosene as the carrier fluid to suspend the particles

Give instructor top 3 project choice list
My top three project preferences were Perfume, Corn Starch, and Chaos Theory, in that order. The project I am currently working on is Corn Starch.

Write problem statement
Develop the non-Newtonian fluid, corn starch, and show how this fluid holds certain properties that other fluids do not.

Assign Task1
For week 1, I will purchase corn starch materials and produce sound vibrations with the CL 129 speaker cones.

Compare actual work done to Task1
The work completed for the task one is quite extensive. The materials needed to produce the non-Newtonian fluid were purchased, vibrations from the speaker cone was properly produced, and the corn starch mixture was developed.

Week1 Narrative
Three major contributions were made towards this project this week:
 * 1. Obtain the materials to create the cornstarch and water mixture.
 * 2. Produce vibrations from a speaker cone.
 * 3. Develop the cornstarch mixture and study the properties of the non-Newtonian fluid.

First, the materials to create the cornstarch and water mixture were obtained. These materials were cornstarch, a stirring rod, a mixing bowl, various sized measuring cups, and water. No major problems occurred when completing this task. The amount of cornstarch that was obtained this week is sufficient for continuing further experiments with the cornstarch. Therefore the completion of this task is necessary for completing this project.

The next task was to produce vibrations from a speaker cone. Unlike the first task, problems did occur while attempting to produce sound vibrations from the CL 129 speaker cone. The only major problem that occurred as this task progressed was regarding the setup of the speaker cone. It was initially setup in the computer and with a youtube video, sound vibrations were to be produced. However this did not occur, therefore solutions were thought of and tested. It was determined that the solution to this problem was to set up the speaker cone with the sweep function generator, not the computer. The sweep function generator allowed vibrations to be produced from the speaker cone, and therefore completing this task.

The last task that was accomplished this week was an experiment with the cornstarch mixture. With the materials that were collected in the first task, the cornstarch and water mixture (also known as oobleck) was created. However a problem occurred at this stage in the experiment. By referring to a cornstarch non-Newtonian fluid recipe found on google, the developed mixture did not show the properties of oobleck. The solution to this was to add more cornstarch, and therefore produce a more solid and viscous mixture. The next problem was taking this experiment further and use an object that produces vibrations, such as the CL 129 speaker cones. Several solutions were devised, however none of them succeeded. Thus the experiment ended and will be continued at the beginning of next week.

See youtube video of experiment for more information: Oobleck Experiment

Week1 Peer Review
I posted a comment on Z. Hill's discussion page regarding the documentation of work that should be posted.

Assign Task2
For task two, I will show the unique properties of this corn starch mixture by developing a larger cornstarch mixture.

Compare actual work done to Task2
The work completed for task 2 was extensive. Problems mainly occured when producing the large quantity of cornstarch. But once the mixture was completed the cornstarch experiment was succesful.

Week2 Narrative
The photos taken during this week's tasks are shown on the right side of the week 2 narrative.

The purpose of this week's task is to develop a large amount of cornstarch, and experiment with it. However, problems occured. The main problems that occured were regarding purchasing cornstarch and stirring the cornstarch. Once these problems were solved, the experiment was able to begin. And with the experiment, the properties of this mixture were recorded.

The first issue was determining how much of the cornstarch should be purchased. A cylinderical container was to be used to stir and hold the cornstarch mixture, however this container was not a perfect cylinder. This problem prevents a proper volume calculation and therefore an improper amount of cornstarch to be purchased. To solve this problem, the average radius was taken instead of the top or bottom radius of the container. Another problem that occured was finding a store to purchase the large amount of cornstarch. I initially visited Safeway, however since cornstarch is not a common purhcase, the amount of Safeway cornstarch was limited. Therefore another store was to be considered. BJ's was used to purchase 22 containers of cornstarch for approximately $60.00. With the cornstarch purchased, the next step to completing this process could begin, developing the cornstarch mixture.

The next set of problems that occured were regarding how to stir the mixture. Since cornstarch and water is a non-newtonian fluid, there is a large amount of resistance when stirring it. The first problem was using an appropriate stirring rod. The original stirring rod began bending and was deemed insufficient. Therefore another stirring rod was obtained. With an appropriate stirring rod, the stirring process began again. The last problem that occured was determining how to stir the mixture. Since the non-newtonian fluid is most efficient with a two parts cornstarch and one part water ratio, it was difficult to determine a method for mixing the cornstarch. It was determined that it is best to stir a mixture that is mainly water, and when the mixture is nearly complete, only cornstarch is added. These solutions brought interesting properties not considered before to the large amount of cornstarch, however the experiment has not been completed yet.

In the experiment, 20 BJ's containers of cornstarch were used totaling 20 kilograms of dry cornstarch, and 20 liters of water. The experiment was interesting, and several new properties were determined and recorded using a camera. The videos that were during this week are shown below:

The photos taken during this week's tasks are shown on the leftt side of the week 2 wikiversity entry.

 * Pushing and Pulling Cornstarch Vertically
 * Forming a Ball with Cornstarch
 * Cornstarch Waterfall

 * Placing Feet into Cornstarch
 * Walking on Cornstarch
 * Stomping on Cornstarch

Week2 Peer Review
I posted a comment on Ayapici's discussion page regarding how he should begin posting his information for this week.

Assign Task3
For task three, I will begin researching and preparing an experiment that explains the physical properties of cornstarch as a non-Newtonian Fluid.

==Week3 Activities==

Compare actual work done to Task2

Possible experiments were researched to determine how to measure viscosity. After looking into several experiments, preparation for the shear stress vs. strai rate experiment began. This required constructing a trough apparatus, collecting the necessary materials, and forming a method for completing the experiment.

Week3 Narrative

To accomplish this task, research is needed to determine how to qualitatively and quantitatively define viscosity. Several websites were researched (shown below), however the most helpful source was this pdf file: Viscosity and Fluid Flow

Websites that were researched:
 * Introduction to Viscosity, Shear Rate, and Shear Stress
 * Dilatant or Shear Thicking Fluid
 * Fluid Mechanics

The summation of this research can be explained using the picture in the pdf file (in the first link) and this equation: Viscosity is the shear stress and strain rate ratio. Shear stress can be defined as the force applied divided by the area of the force, this value is a pressure. The strain rate is the displacement of the fluid as the force applied moves the fluid. By varying the shear stress acting on the fluid, and collecting the strain rate, I can graph this fluid and determine whether it holds non-Newtonian or Newtonian fluid properties. 'Bold text'

I spent the remainder of this week by collecting and constructing the equipment necessary to determine the strain rate and shear stress of fluids. The apparatus needed to determine the viscosity of a fluid, the trough, should properly contain the fluid and have a mobile plate on top of the fluid. The plate on the top is where the applied force will occur, moving the upper molecules of the fluid, since the bottom molecules will be staitionary a shear stress is formed. The applied force will be a mass being pulled by a spring scale along the top plate. The dimensions of the apparatus, the trough, is 5 feet long by 5.5 inches wide. The thickness of the fluid will be 1 in, therefore 3 containers of BJ's cornstarch will be used. The process of constructing this apparatus took a sufficient amount of time and the procedure of constructing this is shown by the pictures on the left and right. There are other materials that are needed to determine the shear stress and strain rate of a fluid, the materials for this experiment are listed below:

Cornstarch
 * A Newtonian Fluid, such as water
 * Trough to contain fluid (Pictures shown to the right)
 * Spring scale
 * Different masses
 * Excel Program to complete calculations

Using the information that was collected and the materials listed, I will determine why cornstarch is a unique fluid. The goal is to graph strain rate over shear stress of a Newtonian fluid and a non-Newtonain fluid. With this graph the physical properties of cornstarch and other non-Newtonian fluid can be explained. With this experiment (that will be completed next week) all of the cornstarch videos can be explained quantitatively.

Week3 Peer Review
I posted a comment on Ayapici's discussion page regarding how he should begin posting his information for this week.

Assign Task4
For week 4, I will conduct the viscosity experiment to determine the shear stress, strain rate, and viscosity of cornstarch.

Compare actual work done to Task4
The experiment was completed and the shear stress, strain rate, and viscosity were calculated. However, these values were not an accurate estimate due to problems that occured during the experiment.

Week4 Narrative
Using the tools and materials that were collected from last week, it was not difficult for me to set up the experiment. Once the experiment was set up, I began preparing the cornstarch mixture, and since this experiment needed to be more precise with the consistency of cornstarch, the ratio was measured. The initial ratio was 2 parts cornstarch and 1 part water or 3 liters of cornstarch and 1.5 liters of water. This ratio produced a rather thick fluid, too viscous to perform the experiment. With this fluid, the velocity of the shear was too small resulting in a large viscosity. To solve this problem, water was added to the mixture resulting in a less viscous fluid. With this fluid the experiment began again.

 * Viscosity Experiment
 * Rolling Cornstarch

The procedure of the experiment involved three people. One person attached the applied force apparatus to the cornstarch fluid, another noted the displacement and time values, and the last person watched the force-time graph on the force probe display to keep an even force applied. After each trial, the average applied force and time were recorded into an excel spreadsheet which calculated the velocity, shear strain, strain rate, and viscosity. However during the experiment, the force applied values changed significantly resulting in inaccurate data. Due to this large error in the results, it was concluded that the current viscosity experiment could not produce valid results unless a more controlled system were devised. The possible sources of error were:

 * The consistency of the cornstarch changed with respect to time.
 * Other extraneous forces were at work. Such as the downward force of the block acting on the cornstarch.
 * The shear block did not produce a constant velocity.
 * Inaccurate measurements from the force probe.

These problems resulted in invalid data and results. However, a future team working on this project can repeat this experiment, learn from these problems, and produce a more controlled environment for the viscosity experiment.

Week4 Peer Review
I posted a comment on Ayapici's discussion page regarding how he should begin complete the ferro fluid experiment and post it on wikiversity.

Start Next Project Week0 activities
My top three project preferences were Perfume, Chaos Theory, and Escher in that order. The project I am currently working on is Perfume.

Engineering Projects/Engines/Howard Community College/Fall2011/501 BigBlock

Problem Statement
Create a multi-cylinder Stirling Engine out of common house hold materials for little-to-no cost and make it simple in design so it can be replicated by anyone. We want to make something similar to the engine in this video.

Team Members

 * ARoberts
 * Cdiffendal
 * Joon Kim

Summary
The problem that arose in our last attempt at creating a stirling motor was that we tried to work off of an model that wasn't showing much success in use. So we decided to change and create our own working motor. This would better portray our knowledge of how a Stirling Engine actually works. We have decided to base our design from a multi-cycle engine that works in the same way a car engine would work, as portrayed in this video. To the right, you can see model of one of the piston structures that was made in Pro-e Wildfire 5. These pistons will be in a line of four in succession and be attached to a crank shaft at the top. From this, we should be able to receive motion powerful enough turn a wheel and propel itself.

Story
Over the month we worked on this project we all decided that it would be best to build engines separate from one another because it produces more results on techniques that work and techniques that failed. In week one we all gathered building materials and began making our engines. After trying to make engine out of the commons house hold materials seemed to be in effective we started using more commercial building parts like wire conduit and PVC tubing that can be found a any hardware store. After we discussed that the ruffles in the walls of most food cans were making the motion of the styrofoam displacers to hard we made the decision to make the compression cylinder with smooth walls out of the conduit. We also had other failures while working individually that led to good ideas on how to make better parts. For example we one of us tried to make a crank shaft out of welding rod because they thought it would be stronger. In fact the welding rod was tough to bend and both offsets needed for the pistons to function correctly were not bent right. Another group member suggested using a metal coat hanger because it was easy to bend with a pair of pliers and it would be strong enough to keep its shape when the pistons put stress on it. Over the four weeks we worked on this project we weren't able to make an engine that worked on its own, but we were able to find ways to solve problems for future groups attempting to this project that will jump start their work.

Decision List
Our first decision is to have one person create a design on a CAD program and the other two will build the design out of common house hold materials. We decided to make make engines individually instead of as a group. This allowed us to try and fail on our own and come back to class and discuss our problems with each other ultimately producing an engine with the greatest possibility of working.

Material List

 * Aluminum Can
 * Welder's rod
 * PVC piping
 * Rubber glove/ rubber band
 * Clothes hanger
 * Aluminum foil
 * styrfoam

Software List
Pro-Engineering Wildfire 5.0

Time
Time estimates and actual time consumed measurements helps justify salaries (grades). The only way to gain respect for estimated project time and costs is to practice.

Tutorials
The materials we used can mostly be found around the house. Any kind of aluminum or tin can may be used and other items such as wire hangers, rubber bands and rubber gloves can be found in anyones home. Some other things like the epoxy is found at any hardware store like home depot, or ace. As for putting the materials together it just takes time finding pieces are close in size and finding ways to attach them. One problem we had was finding out how to hold the connecting rods together and attach them to the crank shaft. We found that using ring style crimp on connectors are the best way to attach these pieces because they come in just about any size and are easily found at any hardware store. Most projects consist of making instructions to jump start the next team, shrink the learning of tools and software to the minimum, advice on where to purchase materials, how to assemble, etc. Tutorials modified or created are described here with links.

Next Steps
The next steps to this project will be fine tuning the engine and then reproducing the same engine a few more times and creating a crank shaft the allows the engine to perform a full cycle one after the other.

Helicopter/Howard Community College/Fall2011/501 Eagles

Problem Statement
-Download games from ITunes to play on ITouch. -Arduino -Improve instructions - associated with battery - capturing recording video -Flying with PC

Team Members

 * Chaagii
 * Dcalderon
 * Andyn6361
 * Dkromer1996

Week 1
For week 1 User:Chaagii 0817/enes100/eagles member was working how to play TargetHunter game by using Itouch and Ar.drone. That game is designed to play person who likes to play alone. In order play that game you will need only 3 things: ardrone, Itouch/Iphone/Ipad, and stickers. What you need to do is to put stickers wherever you want and basically your stickers will show up your enemy. Therefore, you need to destroy them to get credits. By earning credits you will able to upgrade your equipment. TargetHunter costs 3.99$ in apple store.

Andyn6361 was tasked to find an application that records the flight of the Ar. Drone. An application called Drone Ace was able to record the flight. A problem arised as the battery lost substantial amount of power as the helicopter was flying. Another task was assigned to find high-efficient batteries. It was determined that the longest flight time a battery has provided was 20 minutes but there is a chance of damaging the motor.

Dcalderon was to start working with the Arduino Uno. The only problem was that this member lacked the knowledge of how to function the Arduino or how it works. With some research, for week one this member was able to download the software for the Arduino on a computer. He then was forced to update the driver of the Arduino on this software due to that the Arduino was not carrying out the commands cause it was using the wrong board for the codes. After doing so, this member carried out one of the simple tasks that the Arduino has to offer as examples which is blink an LED.

Week 2
For week 2 User:Chaagii 0817/enes100/eagles member started working on AR.Race Ar.Race Game and AR.FlyingAce Flying Ace. We discovered that those games are available for free in Application store and Itunes. However, you will than two Ar.drones and two Iphones/Ipads/Itouchs because those games are designed to play on multiplayer mode. Also, AR.Race required to have traffic cones, which costs almost $100. AR.Race is designed to race through cones, but Ar.FlyingAce is designed to battle with friends by using ar.drone. This game is almost same as TargetHunter; however, TargetHunter doesn't have multiplayer mode and you have to pay to download this game. People can choose outdoor hull or indoor hull to battle, but if you are using indoor hull you should but special kind of stickers, so camera can recognize as an enemy. Ar.drone automatically recognize you as enemy when you use outdoor hull. If you want to buy indoor or outdoor hull just go Parrot store

Andyn6361 was assigned to use the battery charging station to charge batteries and record them. To record the charging, the Logview program is required. Logview was downloaded and the VCP driver was also downloaded. There was a problem with Logview not recording the charging and the rest of the week was used to troubleshoot the problem.

Dcalderon started the second week by trying to carry out a more complex task then just blinking an LED. His intentions were to blink an LED light by using an analog button. As you can see in his individual page when you click on his name and under week 2, he provides videos as well as a more into depth description of his work. Now this task was more complicated and of course surfaced a lot more problems but these problems seemed to be solved. In addition, he also added an Arduino page on wikiversity where if you visit this page you can view a tutorial of how to get started with the Arduino as well as learn more about the Arduino and it's wikibooks page as well.

Week 3
User:Chaagii 0817/enes100/eagles this member started to test TargetHunter game. What you need to do is you need to have stickers or outdoor hull as your enemy. Every time when you destroy your enemy, you will earn credits. Using that credits, you can upgrade your equipments. Also, you will able choose how many enemy that you want etc... If you want to more details, you can go here personal page

Andyn6361 was able to troubleshoot the Logview recording problem as the record button on Logview needs to be on to document the charging. After some trials of charging the batteries, there was a concern as the battery charging station continued to stop at 7-8 mAh, declaring the battery to be full. Proceeded to troubleshoot the problem.

Dcalderon went ahead and tried another task with the Arduino. This time what he wanted to do is control timing. What his intentions were was he wanted to send commands to the Arduino to blink an LED a certain number of times and for a certain amount of seconds. This task is not as simple as just blinking the LED which is pretty simple. This task you have to modify the code in a way that the Arduino will read it and after reaching the goal, it will not make any actions to the LED. This as well you can view in this member's individual page along with more links and pictures. In addition, this member started to work with DC Motors. His idea was to work a DC Motor with the Arduino just as the LED will blink with the Arduino. His attempts all resulted in failure due to that just the Arduino itself can not power a DC Motor.

Week 4
User:Chaagii 0817/enes100/eagles this member basically tested the batteries and figured out that normal battery lasts only7-9 minutes. We need more powerful battery, so we can make tournament in next spring semester. He found out that normal battery have 1000mah. However, we are able to buy more powerful battery through online. For example, you can buy 2600mah battery which you can use up to 24 minutes. One con thing about this battery is little bit expensive $85.

Andyn6361 continued to troubleshoot the problem of the battery charging station stopping at 7-8 mAh. It was discovered that the battery had reached a maximum amount of voltage and the battery charging station wanted to stop the charging before the battery went to overload. Once this was discovered, discharging the battery was attempted. Another task was to create a tutorial on operating Logview. At first, a tutorial of installing Logview was made due to the various necessities Logview requires to operate that may confuse a user.

Dcalderon continued to work with the DC Motors. This time he switched over to working with motor shields and the Arduino. He added motor shields to the Arduino tutorial page. He then started to connect the DC Motor to the motor shield which is mounted on the Arduino and tried to use one of the code sketches that ladyada.net offers. This resulted in a failure do to that the arduino software did not recognize the library of words the code was using since it came from ladyada.net. Under Downloads of that page though, this member downloaded the libraries and set them up together with the arduino software to see if that would help recognize the library but still this attempt ended up with more failures and frustration.

Story
For this project we had four members each all with different tasks to take and work on over the course of four weeks. We divided the tasks with one member, working on how the drone records while in flight and as well as worked on the batteries of the drone. The second member worked on one of the drones and trying to establish connection with the drone and a PC. The third member worked on trying to get the drones to work on an itouch and play games that can be downloaded as applications from itunes. Lastly, the fourth member tried to become familiar with the Arduino Uno in order to be able to later work with the motors of the AR Drone.

The first member, ::Andyn6361, was the one in charge with the recordings the drone made and working with batteries for the drone. He first started out by looking for ways to be able to record video for the drone while in flight. He found out about applications that can take good video as well as take pictures but these applications involved purchasing where some involved a cost of $5.99. In addition he researched and found out the life span of a battery while the drone is in use. He also did some testings using a dual power unit to see how much electricity is being charged into the batteries.

The second member, ::Dkromer1996, was the one in charge of trying to establish connection with the drone and a PC. His weeks involved the downloading of programs and softwares that he can use in order to get the drone to function with the PC. Every time though, he would surface problems that involved extracting files as well as looking for files to use to establish connections. After a lot of trials that would only result in problems and failures, he decided to start all over as when he first started to look for better programs/softwares/files. He also tried trial and errors of arranging these files in order so they can work with each other to try to establish precise connection. Toward the end, he wanted to help one of the members to establish the connections of games that will work for both apple and android powered phones.

The third memmber, ::Chaagii, was the one in charge of getting the drones to work in playing games on an itouch.This involved the purchasing of applications such as TargetHunter that was $3.99. In his progression of the weeks, this member started to play with all 3 drones. He ran across a problem with one of the new drones not connecting with the itouch so that was something he looked in to. In addition, he came across the idea of buying traffic cones ($57.99) and or donuts ($49.99). What these items are used for, are for obstacles to play in the games that the itunes market offers of applications. He then decided to use the stickers that the drones brought to put on items as obstacles. He found out how the games were played in order to beat the games and the rules of the games. He also tried working with Android but didnt find that much options to choose from for applications to buy. He only found two applications on the Android market to download for games to play with the Drone. He then found out that playing these games with the drone, it kills the battery faster and it would usually last about 7-9 minutes. He researched more information and found out about other batteries that will expand the battery life of upto 45 minutes choosing the sizes of the batteries in "mah".

The fourth member, ::Dcalderon, was in charge with working with the Arduino. In the first week, he was clueless in working the Arduino. He found out through researching and made a tutorial which is included as a link on this team page or you can simply search for Arduino in the search bar. Some of the tasks that this member was able to accomplish was making a code to make an LED blink constantly. In addition to that he also wrote a code that can get an analog button to work with the Arduino and make the LED light blink. He posted videos of these tasks on youtube.com and linked them to his individual page. Also, he was able to learn more how to control an LED and telling the Arduino how many times to blink and for how long to blink, basically controlling the timing of the commands. From their, he decided to stop working with LED and start working with DC Motors. This way he can eventually get to start working with the motors that the drones use in order to control speed and oneday be able to build a drone of our own. There were a lot of method tried which ended up in failure that included connecting the motor up to the Arduino just as he did with the LED light. This failed because there wasnt sufficient enough energy to power the motor. From there, he turned his frustration over to look for hope in motor shields. He added in the Arduino tutorial, an introductory to motor shield and what they are used for. He found out that this is exactly what he wants to use if he wants the Arduino to work with a Motor shield. Due to lack of knowledge of how the Motor shields work, he is running through a lot of problems in getting the motor shield to work with the DC Motor and arduino.

Decision List
1. Understand the Arduino software => Program the Arduino Uno to perform simple circuit tasks => Program the Arduino to work with Ar. Drone

2. Find gaming applications for the Ar. Drone => Use racing application to start tournament with other Ar.drone flyers

3. Familiarize the Logview software that documents battery charging => Test battery efficiency

4. Find program to connect Ar.Drone to personal computer via wifi => Find applications for personal computer to fly the Ar. Drone

Material List
For this project, we were able to justify the purchasing of two AR Drones more which are $299.99 each. In addition to acquiring these two drones, we were able to also get the batteries that were included in order to experiment with them and develop some theories to try to perfect the life of the batteries for the drones. Also for another part of our project, one of our members was trying to play competition games on his itouch. In order for him to play these games, he would have to download some applications and being that most of the applications required to be bought, he did buy some applications for him to play the drones in game modes. The name of this application is called TargetHunter and costs $3.99. For documenting the charging of batteries, a dual power unit was obtained along with a usb cord to connect the dual power unit to the computer and a wire to connect the battery to the dual power unit.

Software List
-Arduino software (version 0022)- a software that uses programming (C++ coding) language.

-Itunes 10.5

-I Touch 4G

- Windows 7

- Logview

Time
Team members are spending 3 hours in class to discuss project goals and decisions while spending 4 hours of individual work outside of class. In total, 7 hours is spent on working on the project every week with a total amount of hours worked on the project for each person to be 28 hours. With 4 team members in this project, the total comes to 112 hours worked on this project.

Tutorials
We found great tutorial about how to control Ar.drone. Tutorial 1 After this video we believe that you will be able to control ar.drone, so you will be able to play Ar.Race, Ar,flyingAce, and TargetHunter games. If there is anyone wants to learn how to use Arduino, Arduino here is great tutorial that you can use to learn this software. There is a tutorial to download Logview as the installation process is complicated.

Next Steps
Our next steps for the helicopter project consists of the arduino and the AR Drone battery. Our focus for the drone's battery is to have the strongest, longest lasting power to fly the drone for extended amounts of time. Currently the drone can only fly for about 10-12 minutes on a full battery before it dies and ends its flight. Also, the drone's battery charge time is over an hour so we will find alternative chargers to speed the charge duration for quicker charges. Currently, Dcalderon is working with the arduino and progressing with software and light simulation. For the next project, he will continue working with the arduino and a motor shield for the arduino to enhance its capabilities.

The Problem
We want to create a multi-cylinder Stirling Engine for little to no money at all with the help of a CAD design using free software off the internet. We want the design to be simple but effective and easy for anyone to replicate.

Task1
The goal for week one is to start with a CAD design and then determine the materials needed to create the Stiriling Engine we want.

Compare actual work done to Task1
We have a computer design that isn't complete so I went ahead and built an engine that was close to what the design looks like.

Week1 Narrative
During week one I began building my stirling engine out of the easily found materials we discuss on the team page. I used a tin food can for a compression cylinder and a 90 degree PVC elbow for the power piston's cylinder. I used a piece of styrofoam cut into a circle with aluminum foil wrapped around it to help make a seal. For the power piston I used a part of a rubber glove with cardboard glued on either side to help prevent rips in the rubber when it is flexed. I used welding rod for the crank shaft and connecting rods. I tried to put the crank shaft together I realized that the two connecting rods were located on the same point of the crank. This is when I found out I didn't off set the PVC fitting so the rods could connect to the correct spot on the crank. My next step is to pull the PVC off and relocate it at the correct angle.

Assign Task2
The new task for week two will be to re-position the PVC fitting and once all of that is corrected I will make the crank shaft to fit the modified engine.

Compare actual work done to Task2
This week I decided to start over form scratch and make a new engine since the ruffles in the side of food cans allow air to pass by too easily.

Week2 Narrative
This week I began to make a new stirling engine because the old one didn't work right. I deviated from the original plan of make the engine out of common house hold items because the ones I used were not very effective. I started off with three inch electrical conduit and cut it down to 3 and 3/4 inches tall. then I made my own end cap for one side out of 1/16 inch sheet metal and welded it onto the conduit. After that I used styrofoam and aluminum foil to create a new displacer. Also I used new PVC fittings to make the power piston. Once both pistons were made I used metal rod to make the connecting rods that go to the piston. they are all attached by ring style crimp on wire connectors. to make the top of the compression cylinder I used a tuna can that fit perfectly into the conduit and I epoxied it in place. To make everything for this engine it took about four hours,mainly because I had wait for glue to dry. I put my engine on the stove with the heat on low and did my first test run to see if the engine would work on its own. Unfortunately it didn't work but it began to move a little bit, all i need to do now is to figure out why the action isn' smooth. First attempt of my engine.

Assign Task3
For week three I am going to find out what is holding up the movement on my engine and figure out a way to smooth things out.

Compare actual work done to Task3
Over the last week I pulled the engine apart and found why I believed the engine didn't run smoothly.

Week3 Narrative
I had to deal with the problem of the action in all the moving parts being sticky. Both of the pistons were no moving properly and I had to figure out why. After looking over the engine and spinning the crank shaft with my hands I determined that it (the crank) was the problem. So I disassembled the engine and made a new crank shaft. I started by using a wire hanger because its easy to bend. I made the offset for the displacer about a quarter the height of its full stroke which was about 1.5 inches so i made the offset on the crank about 3/8 of an inch tall. Then I started making the offset for the power piston which has a stroke of only a half inch. I was told by Mr. Foerster that the offset for the power piston should be half of its full stroke so the cranks offset is .25 inches. I then reassembled the engine and spun the crank by hand and the action of all the parts was much smoother than it had ever been.

Assign Task4
I plan to make add a some kind of sleeve over the compression cylinder to keep it from having water enter the chamber from ice cubes.

Compare actual work done to Task4
I added a water tight sleeve on to the compression cylinder

Week4 Narrative
I searched for options on how to add a water tight sleeve on my engine and found that hobby shops had small diameter metal tubing that could work just fine. I got a piece of the metal tubing that had a inner diameter of 5/32 inches which would allow a very tight fit around my 3/32 inch thick connecting rod. In order to install it I once again had to disassemble my engine. Then I cut the metal tube down to 2 inches tall which was about a quarter inch taller than the tuna can I had on top of my compression cylinder. I slid the tube over top of my connecting rod and then epoxied it in place and after the epoxy dried it was water tight and it gave enough protection over the cylinder to hold up to 1.5 inches of water from melted ice cubes. Then I found that the supports I made for the crank shaft were not sturdy enough to hold the crank in place while it is spinning. To fix that problem I came up with the idea to have styrofoam cushions to help keep the supports in place. I started by cutting out 4 small cubes of styrofoam about .5x.5x.25 inch cubes. Then using electrical tape I very tightly fastened the cubes on to the supports. I made multiple passes with the tape to make sure the supports weren't going to move.

Problem Statement
We will create a multi-cylinder engine that will be easy enough to be reproduced by anyone.

Assign Task1
I will be making a CAD design of what will be our Stirling Engine.

Compare actual work done to Task1
Found some complications in trying to create the CAD making of our model. Certain functions are a little more difficult then I had anticipated. I will have to continue working on it for this week as well.

Week1 Narrative
Pro-E is a little difficult to use when it is not used on a regular basis. I tried to make one of the pistons as a model for our project but found difficulty when it came to the curve of the channel sticking out of the side. With some research and some memory I was able to get through it. The commands can be difficult if you don't know how to work them, but with the semester of training that I have had beforehand, it was not nearly as hard as it could have been. Though the design is a little basic in design, it portrays what we are really trying to do. We will have 4 of these lined up and attached to a crankshaft. This crankshaft will transfer this rotational motion into motion of a wheel.

I am going to download some games to my IPod Touch, so i can able to play games. There are three different type of games (AR.RACE, AR.FLYINGACE, and AR.PURSUIT) that i can on play on Itouch.

Assign Task1
I am going to test some games on Itouch by using AR.Drone. There is one video how to play game on ipod, iphone and ipad Game IPod Touch game.

Compare actual work done to Task1
I started work on Target Hunter game and tested how it works.

Week1 Narrative
I am downloaded application, which is called TargetHunter. This application costs $3.99 and the main goal is to play game by using Ar Drone. This the video explains how to play. In order to play this game I need to use stickers or outdoor hulls as a target. When your ammo will finish, you should charge the ammo by land Ardrone and wait until it charges. To make this game interesting you can make moving enemies by sticking the stickers. Also, you should try protect yourself; otherwise, your enemy will destroy you. Every time when you destroy enemy, you will get credits with that credit you can upgrade for the better equipments. The main problem that I had this week is I don't have stickers that will allow me to play this game. Tutorial.

Week1 Peer Review
Added positive comments to my team fellow discuss pages. I put my name and date after I read all information that they wrote.

Assign Task2
I am planning to work on Ar.AceFlying and AR.Race, so i can able to race with other AR.Drone if I can get traffic cone.

Compare actual work done to Task2
I am used two Ar.Drones and two IPod touches to connect AR.FlyingAce in two players game. It was successfully connected; however, later on I had some issue with connection. One of the new Ar.Drone was not able connect AR.FlyingAce game. Therefore, I am working on it. I am hoping that next week we will able to play that game. Also, if I can get traffic cones, I will be able to start play that game. Basically, for this week I was trying to play multiplayer games compare to week 1.

Week2 Narrative
I am downloaded AR.Race video ar.race and AR.FlyingAce video FlyingAce from Itunes for free. In order to play Ar.race, I will need to have traffic cone($57.99) or Donut($49.99). I tested how both two games work, but the big problem was connection with Ar.FlyingAce game, so I tried unpair and reset Ardrone. However, it was still not connecting. I didn't have enough time go over that, so i am going to work on that problem. Next week, I am planning to play with with my teammates. I am curious that android have those games. Maybe I will try to find out from android because it is very different from Itouch. I found some demo for AR.Race and AR.FlyingAce AR.Race and AR.flyingAce.

Week2 Peer Review
Added positive comments to my teammates fellow. Some of my teammates are not filling up personal page on time, so I am not able to write any positive comments.

Assign Task3
Next week I am planning to finish work on Ar.Race and Ar.FlyingAce. I am going to start working on Ar.drone parts.

Compare actual work done to Task3
For this week tested TargetHunter Game successfully. This game is designed for people who likes to play a single player game. However, Ar.FlyingAce and Ar.Race is built to play in multiplayer mode.

Week3 Narrative
I worked on TargetHunter game for first week, but I hadn't chance to play this game because I didn't have outdoor or stickers to play that game. However, I learned how to play TargetHunter game properly. First of all, you need download that game from application store or from Itunes. Then, when you have that application. You should turn on Ar.drone and turn on your Itouch/Ipad/Iphone wifi connection. Since you connected to that game, you should choose how many enemy. After that you have two choices you can make your enemy by putting special colored stickers or you can use outdoor hull. When you start the battle, you will see on the top right side with blue colored thing is your life. Also, you will see on the top left side there should #20 that is ammo. When you your ammo will be 0 you should land to charge your ammo. If you will go close to your enemy, your target lock will automatically detect enemy and your target lock will become red color that means you have to shot. When I completed my mission, I got some credits points that I can use to upgrade my equipment. For example, if I earn 200 points, I will able to upgrade target lock for 1.5 seconds. If I earn 300 credits, my ammo will increase to 30. Also, if I have 6000credits, I will be able to adds another weapon slot. etc... . After, I finished my mission there were results that how many enemy I am destroyed and how many credits I got. In addition, There was time bonus and accuracy bonus. What I got is my accuracy bonus was 68.97% and I got 51 credits, but for time bonus I got 0 point. Moreover, I tried to test Ar.Race and Ar.Flying games; however, I didn't have extra Itouch, so I was not able to test those games. One of my teammate had Android, so i asked to use his phone to play those games. However, when we go to android store we weren't able to see those games. There were only two application for ad.drone, which are Ar.freeflight and Ar.Pursuit. Thus, We can only play those games on Itouch/Ipad/Iphone. I just want to share you can download those applications to your Itouch/Ipad/Iphone Applications

Week3 Peer Review
None of my teammate wrote something on weekly summary page; therefore, I was not able to write any positive comments to my team fellow. I hope they will finish by Monday.

Assign Task4
I used almost 3 batteries to play 3 games; therefore, I would like to record information how long does batteries last if we play with ar.drone. Also, I would like to find out which battery is good and which battery is bad.

Compare actual work done to Task4
This week I am worked on Ar.drone batteries.

Week4 Narrative
For this week I tested two batteries of ar.drone. I found out that both batteries are last 7-9 minutes, even batteries were new. You need to charge the battery approximately 90 minutes. Also, as soon as press take off 50% of battery drops down. In order to make tournament, we should order powerful batteries. Regular ar.drone batteries are 1000mah £29.98. However, you can buy more powerful batteries online 1300mah,2200mah,1500mah, and 2600mah. Every battery has different life 1300mah $49.99 last 10-13minutes, 1500mah $36 last 13-16min, 2200mah ($48) last 16-20minutes, and 2600mah $85 last 20-25minutes. I tried to post links but wikiversity not allowing me to put link in here, so I send links through e-mail. There is video that someone tested battery life of Ar.drone from IPad battery test life. There are other ways to expand the batteries. For example,you can buy more powerful batteries from amazon.

Week4 Peer Review
Only one of my teammate filled out week 4 except him nobody did anything, so I wrote positive comments on his page. To other member I just wrote nothing.

Wikiworld - Commons and Education/Wikilearning

Wikilearning
Public EtherPad document to write Wikilearning manifesto.

Individual learning

 * Alienated forms (such as school learning in a standard classroom)
 * Emancipatory forms (such as self education, self teaching, autodidacticism http://en.wikipedia.org/wiki/Autodidacticism)

Learning with others

 * Paulo Freire's contribution
 * Collaborative learning etc.
 * Sugata Mitra's experiment http://www.youtube.com/watch?v=dk60sYrU2RU

Learning for others

 * Wikilearning
 * Contributing, collaborating and sharing
 * Amateur learning http://en.wikipedia.org/wiki/Amateur

"A working definition of wikilearning could be as follows:

1) the group is self-organized and volunteer (in opposition to pupils and students as captive audience in the school settings); this naturally includes the option of starting new groups (so-called 'forking'),

2) all (study) materials are available on the basis of open access (content is created under copy left licenses, if licenses are needed at all) and

3) everybody has equal possibility for contributing, commenting and working on the materials right from the start.

An additional condition could be 4) to limit wikilearning to activities that are mediated by computer networks (in practice, the Internet), but that seems an unnecessary move, as the point of wikilearning is also to disseminate the practices out of the cyberworld into other spheres of life.

Wikilearning can also be defined using a pedagogical maxim launched by the French philosopher Jacques Rancière (1991): "Teach what you don't know." The maxim represents the ultimate equality between students and teachers, between people, as it does not take into account any distinctions like age, previous schooling history, or gender that are often taken as a basis of pedagogical rank. Thus wikilearning in its ideal form and full fruition but also in its many practices signifies radical equality between different people, and differs drastically from the politically regulated and curriculum directed schooling systems governed by the state." (See http://suoranta.files.wordpress.com/2010/09/wikilearning-as-radical-equality.pdf)
