Write problem/project Goal
My project goal is to construct a wind turbine that can turn wind energy into storeable and useable electrical energy.

My First Task

In a wind turbine, the blades turn rather slowly. Over the weekend, i will look into gears that take the slow rotations of the wind spun blades and increase the amount of rotations needed so the motor can produce energy. Also i will test an old battery to see if it has a charge and can hold battery life.

Summary of actual work over first weekend
For my first week of work, I wanted to focus on the gears that would be needed to increase the low rpms that the blades provide. As the first week started, i realized that the most important part of our project is finding a working generator. In the process of finding and understanding a generator, i feel like our team has started working better together.

Week1 Narrative
Over the weekend i looked into the difference between voltage sources and current sources. I found out that our generator is a power source. Power is voltage x current. I want to varify this with my group when we meet today.

My Second Task
Now that my team has found a working generator with blades attached, i need to figure out how i can increase the voltage. So far our generator has only produce at max 4 volts.

Summary of actual work over second weekend
During this week, i did no work with the generator that was found, instead my team decided to make a smaller version of a wind turbine to power an LED. This week, i feel like we played alot and got somewhat off topic. However, from this playing I have learned how to measure voltage and amperage, which is really useful for where i want to take this project next.

Week2 Narrative
Over the weekend, i identified voltage and current, during this week i measured the voltage and current of the smaller turbine.

My Third task
Over this weekend, I want to get back into focus on my problem, which is converting the rotational energy in electrical energy. I'm going to bring in a hair dryer so that i can measure the volts and amps produced by a constant wind source. The compressed air runs out too fast and produces energy like a negative parabola (goes up, reaches a max, then falls to nothing). With this constant wind source, i will be able to figure out how many volts and amps exactly the turbine can produce with this specific wind energy. After finding this information, i can calculate power using one of the formulas i have stated below. I want to find a battery with the same amount of volts so i can recharge this battery, and use it to demonstrate that my turbine has worked.

Formula for Power:

P=IV P=I^2R P=V^2/R

P(power) I(current) R(resistance) V(voltage)

Summary of actual work over third weekend
At the end of last weekend I really wanted to recharge a battery and use that to power a small car. When i started thinking about it, i realized that charging a battery would take a long time and i wanted something that could wow everyone on the spot. That's when i started thinking about lights. Halfway through the week i looked up parallel and series circuits. I drew a parallel circuit that could could power LEDs. Now my end result for demonstrating that the wind turbine works is powering lights!

Week3 Narrative
On Tuesday March 6, i tested the mini turbine design for volts and amps. I brought in a Revlon hairdryer to use as a constant wind source. When i setup this test, it failed because the hairdryer could not put out enough wind energy to get the blades to spin. Next I upgraded to a leaf blower. When i set up this test, it succeeded, you can see that in this video I got a measurement of .21 volts and 1.0 milli amps. From this test i could conclude that the mini turbine would not be able to charge a 6 or 9 volt battery like i had hoped.

On Wednesday March 7, I met with my group and started working with a larger wind turbine. Then i test this turbine for volts and amps as well. I did the same set ups as before, testing current the circuit and testing voltage  the circuit with a leaf blower. For voltage, i measure 9.75 volts and for current, i measured 2.0 milli amps. With these test results, i could use the formula, P=IV to calculate how many Watts of power my turbine is producing. This turbine would be able to power a battery like i had wanted.

On Thursday March 8, I designed a circuit that i would want to design to more visually show that the wind turbine worked. I came up with this design.

On Friday March 9, I implemented my design. I found four LEDs, one red, yellow, orange and green. I wired these LEDs to a breadboard and hooked it up to the turbine. With the leaf blower again, i powered the turbine and the four LEDs lit up. You can see this in a short video i made.

My Fourth task
This weekend I want to connect more LEDs to my breadboard. Now that i'll have 8 LEDs, i need to look up how much resistance i'll need or if the voltage is divided enough along my circuit so that I won't need a resistor. This is something i'll decide over the weekend so that i won't blow out my LEDs when I'm testing the wind turbine. Since i have already proven that my wind turbine can light the LEDs, i want to get a little more complicated and try to make them blink! For this i wanted to use switches, so i could turn some LEDs on and off. Or i was thinking about using the arduino to tell the lights to blink without me having to physically do it. These are all ideas that I'm really excited to share with my group.

Summary of actual work over fourth weekend

To get the LEDs to blink, i wanted to put switches or breakers in my circuit. Instead of going further with this idea, my professor suggested a 555 timer with a capacitor. I found this video on youtube of a girl who demonstrated how to excute this idea. I want to incorporate the 555 timer into my own project.

Week4 Narrative

Over the weekend, I cut, stripped and wired 4 more LEDS to my breadboard. Now in total, one of my breadboards has 8 LEDS. I used this LED calculator that i found on Kyle's work page to calculate the resistance needed in my circuit. I calculated that i needed 680 ohms of resistance when using the turbine with the radiator fan blades. I then decided to leave my original circuit alone and start another bread board circuit that would be more organized and incorporate a 555 timer. So far I've been using this wikipedia page to learn more about 555 timers and find a starting point to incorporate it into a design. I've been playing with this breadboard to figure out the right way to wire everything together.

3D Scan

Write problem/project Goal
To use 3d facial recognition from a Kinect to take roll in a classroom.

My First Task
Investigate facial recognition software for web cams and the Kinect.

Summary of actual work over first weekend
Looked into Veriface program and it's operation of facial recognition. Used the face recognition program and saw how it worked. Noticed length of time it took for it to recognize a face. Found evidence of a database of faces for security purposes.

Week1 Narrative
First, ran the webcam program that unlocks a computer using facial recognition program named Veriface. The program took several pictures and required that there was no movement so it can make calculations on facial structures. Looked online for other programs used for facial recognition and found that there are security systems that store a database of faces. Noticed the length of time it takes for log ins (approx 5-10 seconds of facial recognition), also there needs to ample amount of lighting for the software to scan the face if not achieved the scan can take around 30 seconds of scanning. The setup of the camera is going to need a place for proper lighting.

My Second Task
I am going to find a way to to alter the program Veriface so that it can have a multiple face database.

Summary of actual work over second weekend
Searched online, through program files and discovered that Veriface goes through it's website to store photos and in order to have multiple face database you have to register each person. Through my searches I found another program that is used as an app to automatically tag people in Facebook by using their faces.

Week2 Narrative
First thing I did was looked online to find a way to make the software Veriface compatible with this project. Being that it already recognizes faces to log someone into a computer the next step I took was to see if it can store multiple faces. I tried several Google searches ("how to use Veriface to recognize multiple face," "how to store files in veriface," "Veriface hacks," "Veriface alterations," "Veriface multiple users"). My search result didn't lead to anything besides through my last search, "Veriface multiple users" I discovered that each user has to register an account with Veriface according to "http://forums.lenovo.com/t5/IdeaPad-Y-U-V-and-Z-series/Veriface-multiple-users/td-p/20954." Being that is not ideal for a large classroom setting and with no help from my other Google searches, that created a problem. The multiple solution I came up with for the problem was using a different program and look through Veriface system folders to see if the photos were stored in a folder so I could alter them. Exploring the program folder I couldn't find any folders for the pictures. I used Google("Veriface picture folder") again for some help and discovered that the pictures are hidden and that altering them will require a re-install of the program according to, "http://www.justanswer.com/computer/6a8j7-enter-picture-veriface-login.html." I went to my next possible solution and started searching for another program. Internet searched, "facial regognition" and I found a website, "http://face.com/" This software is used to organize and automatically tag people in photos that are put on Facebook.

My Third task
Look to see if programs from face.com and Picasa will work for this project.

Summary of actual work over third weekend
I looked in to how face.com works for facial recognition. Realized that the website requires internet web pares and cannot be operated locally. Went on to use picasa software and it appears that it can work to a certain point, the facial recognition part. Picasa scanned my whole computer for picture files and detected faces within my photo albums.

Week3 Narrative
Went to face.com to see if I can get the website to work locally on a computer. Came to the realization that the site is designed to work off of internet pages. Seeing that it may be complex with a classroom environment I went to my back up picasa.google.com. I downloaded and installed the software to my PC. Upon installation it asked to scan the whole computer for picture files. This process takes about 30 minutes and puts hundreds of useless photos in the Picasa library and effects the facial recognition time DO NOT DO). Once files are in the library the software automatically puts boxes around faces in the picture and allows the user to tag people in that photo. After several photo tags, some photos automatically facially recognize and get tagged by the software. From that process you can sort a person into a single album or sort by the date the photo was taken. Which can be useful to the project of taking roll and checking past attendance. The first tag is important to recognizing the rest of the photos and it needs to be a straight shot. The recognition program has a harder time recognizing faces from a profile view. Lighting is also a big factor with the facial recognition.

My Fourth task
Get Picasa to do what the project needs and come up with a way to mount the Kinect or webcam.

Summary of actual work over fourth weekend
I got Picasa to work and got another program Yawcam to work as a motion detector for the project. Now when people walk in the door Yawcam takes a series of pictures and Picasa uses it's facial recognition to identify who it is. I didn't come up with a way to mount the kinect or webcam.

Week4 Narrative
My first goal was to clear the library for Goodgle's Picasa program for a fresh new start. Learned that Picasa has an option to search files continuously and that is all how to remove files from the library. I designated one single file for a continuous search and that was the file that my webcam pictures were saved in. I took several pictures with Youcam the program used for my web cam and observed how the pictures went to Picasa instantly. Youcam has 3 second timer for every picture. From there Picasa was able to detect who I was with good lighting. Since the project is for a classroom setting and manual pictures are not ideal. I searched online to see if Picasa can detect faces in short video clips. I couldn't find any conclusive evidence but I tested it anyway. It didn't work. I looked online to find a motion sensing webcam program. I found a freeware program called Yawcam. Downloaded and installed program to my pc from www.yawcam.com. Through running the program I found the motion sensing function of the program. It has additional security features such as online streaming and password protection. Opening the window motion detection for Yawcam the program allows change in where the motion detector scans to how many pictures it takes to seconds. For this project I set the camera to take 5 pictures with an interval 1000 milliseconds. Set the motion detector to center screen to allow the camera to take pictures right when someone opens the door. Then I chose the save path to be the same file that Picasa scans continuously and used Yawcams time stamp feature for saved files. Appears to work.

 Team Page: 3D Scan

Write problem/project Goal
Use the Kinect to automatically check attendance in classrooms

My First Task
Download and explore the functions of Microsoft SDK Toolkit and Drivers for the Kinect. Explore how Kinect work.

Summary of actual work over first weekend
My assigned task was to download the SDK Toolkit from Microsoft and it went smoothly. I was able to complete my assigned task.

Week1 Narrative

My assignment was to download the SDK Toolkit from Microsoft and try to explore what the Toolkit does. As I explore the SDK Toolkit, I found that it was able to detect a skeleton view of ourself, so we can use this to detect students as they come into the classroom. I also come across a voice recognition applications where it can record and detect where the voice is coming from, this feature can probably be used to add extra security for users.

My Second Task
I will begin programming a software to let the Kinect detect and count the number of people entering the classroom.

Summary of actual work over second weekend
I was assigned to look for open source toolkits for the Kinect that have the feature of counting and identifying the number of people that enters and leaves an area. I was not able to find any toolkit for the Kinect but came across Kinemote, where we could use it for another purpose such as adjusting the lens using the computer instead of manually adjusting which isn't safe.

Week2 Narrative
I was assigned to tweak the microsoft's kinect skeleton view toolkit code that I downloaded last week to make it count and identify the number of people entering and leaving an area. As I look through the toolkit's code, it is very difficult to follow their code because it is always referencing multiple classes, and I am not very familiar with C++, I am more familiar with java. I decided to search online for an open source toolkit that might have already have the counting feature. I came across Kinemote. It has multiple files to download and needs to be installed in a certain order. This toolkit did not actually have the counting feature, but this toolkit did have something we needed for another purpose. As we install the Kinect in the ceiling, there will be in some point in the years where we will need to recalibrate and adjust the view of the Kinect. Moreover, we do not want to go up to the ceiling and manually move the Kinect's lens because the Kinect's lens doesn't feel very flexible to move, it seems like that it will easily break if you turn it yourself, so having the toolkit move it by just scrolling is much safer. Here is a link to a demonstration to the Kinemote toolkit: http://www.youtube.com/watch?v=nVha8sI4qNw&feature=youtu.be

My Third task
Look for open source toolkits for a regular webcam instead of kinect.

Summary of actual work over third weekend
My assigned task was to explore different software and programs to count and detect individuals walking by with the use of a regular webcam.

Week3 Narrative
As I was researching on youtube what others have done to achieve what we had as our project goals, I came across two different software. One software was called KeyLemon and the other one was called Digifort. KeyLemon is a facial recognition software that identifies individuals to lock and unlock user profile. One of the pros of using this program is the ability for it to track even as your faces evolve, new haircut or as we grow up it tracks the changes of our facial feature by the ability to take a picture a day for it to track our facial feature. Moreover, this software has the ability to trace where the picture was taken, this feature is really great to know where student are, if they are skipping classes in high school, or just to check attendance in schools. I found Digifort from a youtube clip in this link. However, after reading through the comments and descriptions, this was a software he programmed himself using OpenGL and OpenCV. I did not look into OpenGL and OpenCL very much, but I searched about it and came across that it was an open source programming language for computer vision as stated in this link. I did not look into OpenCL very much this week because I was exploring KeyLemon and it's feature and will be looking more into OpenCL the following week.

My Fourth task
On the Fourth Week's Task, I will be exploring more into OpenCL and OpenGL's programming language and hopefully be able to come up with what the person has in his youtube video. Moreover, I will be designing a series of structures on where and how to mount the webcam in the classroom to have the best view of everyone comeing into the classroom.

Summary of actual work over fourth weekend
How is what you did different than what you planned? This weekend, I was assigned to explore Microsoft C++'s language so that we can try to start coding a program that would be able to recognize and count people and implement it with a regular webcam. Also, I was assigned to come up with a design to mount the webcam in the classroom.

Week4 Narrative
Tell a detailed story describing what you did for your team over the weekend. Over the weekend, my assignment was to explore Microsoft C++'s language. I am not that familiar with C++'s language, but more familiar with Java. I downloaded Microsoft C++ and tried to find its similarities with Java eclipse. I came up with an algorithm that could be used in our project to count and identify people.

Motion{  //mehtod that when detects a skeleton structure implemented with Kinect's toolkit I had in Week 1's assignment would take a snapshop  int NumberStudents = 0;  if skeleton detected && skeleton moves left{  for loop (Number of face recognized) //loop until number of recognized identities been recorded in attendance chart String Name= snapshot; //goes to snapshot method and takes picture and returns name of students Attendance(Name); //goes to Attendance method uses the parameter of "Name" to check attendance.  NumberStudents = NumberStudents + 1  }else if skeleton detected && skeleton moves right {  NumberStudents = NumberStudents -1  }else{ null } system.out.print("Number of student attended class was: " + NumberStudents); //displays the number of students attended this class. }  public String snapshot{ Sting NameOfStudent; //takes picture and saves picture to hard drive. NameOfStudent = //search and identify faces from picture database return NameOfStudent; }  public void Attendance(Name){ //goes through Microsoft Excel and search through the parameter "Name" and marks the person present. }

The algorithm did not seem too complicated, The most difficult part was knowing C++'s language. Coding this in Java wouldn't be a problem, but the Kinect's toolkit can only be implemented with C++. So, I started to explore C++ and tried to have the console display "Hello World", but did not know how. So after hours of experimentation with my own knowledge, I finally looked up this video tutorial on how to code and display "Hello World". I recognized that the main(void) method was similar to java's main(String str[]) method, which is where the program would start. The code for displaying "Hello World" is shown below. Over the next week, I will continue to explore and learn the C++ language in order to have this program working.

using namespace std;
 * 1) include

int main(void){

cout << "Hello World" << endl << endl;  system("PAUSE"); }

A design I made for mounting the Kinect is shown below: I think this was the best place to mount the Kinect since it is pointed towards the door and it is below the projector where the Kinect can easily be connected to the instructor's computer and let it automatically run until class is over, without having another computer set up in the corner of the room and have the instructor keep moving to that computer to get the attendance.

Write problem/project Goal
Create a Remote control boat that can navigate a lake and shoot BBs to sink other boats.

My First Task
Create preliminary sketches of possible designs/ redesigns of the existing project. Search for RC car/boat to gut for it's RC parts.

Summary of actual work over first weekend
I did not create preliminary sketches, seeing as we have yet to decide on the final type of boat we want (sailboat, catamaran, etc) I did meddle with steam engines, however. I constructed a rudimentary steamboat out of copper pipe, a tin can, and a styrofoam platform. I am wondering if perhaps we can use steam power to propel the boat rather than electric, and use servos to open and close the exhaust ports.

Week1 Narrative
I constructed multiple rudimentary steam boats out of copper pipe, a tin can, and a styrofoam platform. The first one I built was copper pipe in a helix shape with a flame underneath the helix so that once the pipe was filled with water, the water would boil and be ejected from the ends of the pipe. I later used the same principle to build a steamboat using a tin can as the reservoir for the water, so that the engine could run for longer periods of time.

My Second Task
I will experiment with the buoyancy of styrofoam to determine the ballast necessary (if any) for our boat to remain stable while it is in the water.

Summary of actual work over second weekend
I accomplished what I aimed to over the weekend.

Week2 Narrative
I first acquired a .5 gram of styrofoam, which I floated in a body of lukewarm water. Then I took a number of nails, which had been weighed and found to have an average weight of 3.08 grams, and attached them to the block of styrofoam to determine the buoyancy of styrofoam. This is the block with the attached nails. This experiment showed that a .5 gram block of styrofoam is capable of supporting 25 3.08 gram nails (77 grams) at neutral buoyancy in room temperature water. This indicates that a 7 gram block of styrofoam can float a kilogram of weight without sinking below the surface of the water.

My Third task
Look into possible firing mechanisms.

Summary of actual work over third weekend
I looked at the firing mechanism of an airsoft gun that I own, but I'm not sure if it is the same as the one that Sam is planning on using.

Week3 Narrative
I own a Crosman Air Mag C11 Airsoft Pistol, which happens to have clear sides, so the inner workings are easily visible. However, this particular gun is not electric, so I'm not sure that it can function properly on our boat. If we did end up needing to use it, we would have to build a servo with an offset oval, that would activate the trigger every time it rotated.

My Fourth task
Record what you are planning on doing for the team during the final weekend of project work.

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

3D Scan

Write problem/project Goal
Manipulate a Kinect to have it check attendance by using facial recognition.

My First Task
Look into the open source development tools on the Kinect. And how to use them properly.

Summary of actual work over first weekend
Well I looked into open source software on using the Kinect with the PC. I found KinEmote and MEX(a Matlab Executable Software). The KinEmote is your'e run of the mill software that allows you to use the Kinect, also has a lot of built in software too. MEX allows the user to scan stuff using the 3-D modeling from the Kinect and modeling it with MatLab.

Week1 Narrative
I downloaded various open source software's for the Kinect, and basically played around with them. So I could familiarize myself with the Kinect and its intricacies.I learned that the Kinect can not recognize faces using the camera, but it can count persons as the enter the Kinect's frame. It can count up to 4 people at a time.

My Second Task
I plan on finding the ideal location to mount the Kinect. Moreover I want to edit the Skeletal program that comes with the Microsoft Kinect Software and change the code so it counts persons as they walk in and stores them into an array, and compares them to the actual count of persons in the class.

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

I was assigned and planned on working on the mounts and brainstorm ideas on how to come up with the logic for the coding to count people. I came across various internet users trying to do the exact same thing. There is also a lot of information out online and I learned a lot from forums on people discussing these things. I have attached links and pictures on my Narrative paragraph.

Week2 Narrative
Tell a detailed story describing what you did for your team over the weekend.

I looked very throughly into other work people have done on the project. Came across this YouTube Video This YouTube video actually shows the Kinect counting people as they walk in. Pretty much what we want to do. Looked into forums on people using the Kinect and noticed that many people are trying to do the same thing with the Kinect. Learned that I need to use this function "inline XnUInt16 GetNumberOfUsers const " from Online forum discussing counting people

My Third task
Start actual coding for the Kinect, (I got the logic down and the idea) now its time to implement and see how far I can take it. Use the built in functions that various other users online have recommended.

Summary of actual work over third weekend
How is what you did different than what you planned? I was assigned to code in C# using Visual Basic 2010, and see how far I can take it to start counting individuals. I have been coding over this weekend heavily. Also used Google Sketchup to make a 3_d mount

Week3 Narrative
Tell a detailed story describing what you did for your team over the weekend. What was done this weekend was I did more research into the Kinect on the built in functions and looked through the forums on how people were trying to do the same thing as I. Moreover I installed the Visual Basic Software, here is a link for anyone that wants the software too (its free-ware) Visual Basic. This as the most important thing so far because it gave me a solid starting point on programming for the Kinect There are multiple videos online that I used that tutored me in how to program for the Kinect. Here is what I basically want to do I came across this YouTube Video This YouTube video actually shows the Kinect counting people as they walk in. Pretty much what we want to do. Looked into forums on people using the Kinect and noticed that many people are trying to do the same thing with the Kinect. Learned that I need to use this function "inline XnUInt16 GetNumberOfUsers const " from Online forum discussing counting people Also that a for loop will be needed to implement this code completely. I basically have the logic down and now need to work on the coding. I was having a hard time finding the files although to edit the code.

After this is done I wrote code that starts up the Kinect and turns on all the modes such as -Depth Viewer -Camera -Audio Moreover I also added trouble shooting code that makes sure the Kinect is turned on and properly connected. Here is a link to the videos I watched Videos I also made a mount on Google SketchUp for the Kinect. Here is a 3-D picture. Came across this YouTube Video Lastly here is the Sketch i made using google sketchup Here is the sketch up I have came up with using Google Sketch Up. Basically a mount that will have velcro at the bottom to hold the Kinect.
 * Firstly I had to install the Microsoft.Kinect package so I could reference the Kinect sources when programming
 * Then add another reference which is the Kinect SDK sample

My Fourth task
I hopefully plan on finishing the coding this week so I can have a working counter using the Kinect.

Summary of actual work over fourth weekend
How is what you did different than what you planned? I planned on finishing the coding using the Kinect but ran into several roadblocks that I could not overcome. These were I hard a time modeling the Skeletal Program used by Microsoft in their user SDK toolkit. Here is a link for persons reading this that are interested and would like to continue working on this Link.

Week4 Narrative
Tell a detailed story describing what you did for your team over the weekend. I started programming in Visual Basic C#. Watch the entire video series on the introduction to programming the Kinect on MSDN website. (See previous Week 3 post for link) Learned that the I have to use a lot of references to the SDK. Which I did. Wrote code that does basic start up checks to make sure the Kinect is properly connected. Ran into problems when trying to model the skeletel program. Reason being is that the skeletel program can track users as the enter and assign a skeletal overlay to their body. I wanted to use this pre-existing code and add the which is a built in function that counts the users based of the skeletal read out. I was having trouble writing the code for this in C# coming from a Java background I thought it wouldn't be that hard but I was wrong. C# is a Microsoft language, that I had a hard time grasping. Regardless I did learn a lot about programming the Kinect and various functions that go with it. Here is a video of a successful build of what I was trying. (Note this is not me) Video My team had a back up plan which did end up working which was to use a webcam with motion detection and a facial recognition software together to check attendance.
 * inline XnUInt16 GetNumberOfUsers const (built in function that is very helpful for those that are doing the same project)

Coanda Effect

Write problem/project Goal
Use the Coanda effect in order to manipulate items to move.

My First Task
For this weekend, I am going to familiarize of the principles of the Bernoulli effect as well as the Coanda effect. When researching the Coanda effect, I will simulate it's two primary applications, with liquid and with air, and post my trials.

Summary of actual work over first weekend
In order to establish an understanding of the Coanda effect, I decided to test out the most popular techniques of demonstrating it; with water and with air. Through my research, I concluded that the Coanda effect is manipulated through three important aspects: speed, volume and design.

I personally tested the Coanda effect through air by taking a blow dryer and testing a uniquely designed paper as well as a carefully designed paper in order to demonstrate how the effect is manipulated by the design of an object, the volume (or viscosity) and the speed of the air. I also simulated a device through a unique design involving paper plates in order to simulate the effect; however, these attempts were not as successful as I hoped they would be. The purpose of my designs, and controlling the speed of the blow dryer were to affirm my aformentioned hypothesis regarding the Coanda effect.

Secondly, I tested the effect through liquid. I concluded that the Coanda effect can be demonstrated best with liquid if, and only if, a fluid fills a container at a large volume.

Week1 Narrative
Considering that there is much to be explored regarding the Coanda effect, I decided to test the effects for myself in order to gain a better understanding of its in's and out's. I have seen through YouTube demos the advanced applications of the Coanda effect; to create hovercraft, to design non motorized aircraft rotors, etc. What I attempted to do in the following videos and illustrations is demonstrate how the Coanda effect is manipulated through volume.

In this video, it is demonstrated that a pitcher of water is filled to the top, and is being poured slowly into a sink. As the water is being poured out of the pitcher, it clings to the side of the pitcher and creates a stream that trickles aound the round form of the pitcher. But in this video,the pitcher is not as full as demonstrated in the first video; it doent trickle down the form of the pitcher, rather, it pours right into the sink. The Coanda effect can not be properly demonstrated in this case as a result of the lack volume needed for a liquid to pour to the form of its container.

These examples prove my hypothesis that the Coanda effect is manipulated by volume of a fluid. In this case, volume affects viscocity. Vicosity, the stickiness or thickness of a fluid, has significent impact on the demonstration of the effect.

In this video, I demonstrated my second hypothesis that the Coanda effect is manipulated by design. This is a demonstration of how air flows in sync with a unique form. This paper that I folded to look like a curved dome was designed so that air, sourced from a blow dryer, could flow up and over the form and under the paper, thus creating a lift-attraction towards the blow dryer, which is quite odd considering that blow dryers usually **blow** things away.

In this video, I attempted to create a simulation of a hover craft which will model the Coanda effect by mocking a design. I took a paper plate and made an incision on the top of it so that there could be a source of aif flow for when I placed the blow dryer over it. I cut the rim off of another paper plate and stuck it to the bottom of the first paper plate. I used adhesive putty, commonly known as "sticky tag" near the incisions of the first paper plate to that air can flow between the two plates and down onto the surface. When actually testing this, I was mildy successful. I believe the reason for the failure of this demonstration is that my design wasnt reflective of the "air flows through, around and below" concept needed to properly demonstrate the Coanda effect. I took a second attempt, here, this time for a side angle, but the results were not much different. However, you can see the lift being created as a result of the design of the object and speed of the air flowing through the blow dryer.

My Second Task
I am stuck in a rut as to how to proceed with the project, but that is what I will do...
 * It was recommended that we could demonstrate the Coanda effect through a C.D. player. I am trying to figure out how an item can be legitimately levitated while demonstrating a true Coanda effect.

Summary of actual work over second weekend
It appears as though I'm going back to the drawing board on how to proceed with the project. What is interesting is that there is often confusion between what can be demonstrated as the Coanda effect and what is demonstrated as the Bernoulli effect. Once this is distingushed, we will be able to manipulate design in order to demonstrate them both. It will require much research, though.

Week2 Narrative
For this second week I was unable to work on the project.

My Third task
For this third week, I am going to revamp my original Coanda design and put it to use. For starters, I proposed a reshift of focus for the project from making a pre-constructed tail motor spin, to trying to utilize the coanda effect such that an object at rest on a track can move forward as air emmits from a unique design, on a surface. Air pumps to inflatable matresses were the best proposal for finding an alternative motor. The issues with this composition are that the motor needed to power the air pumps weighed a great deal and would require an immense form of energy, such as from an AC/DC battery to get the inner mechanism (fan) to spin fast enough to emit a stream of air powerful enough to move an object at rest (this apparantly will harm the AC/DC unit). But first, I will work on the revamping of the design. The purpose of this model is to simulate an aircraft moving through Coanda influences.

Summary of actual work over third weekend
This is my final pursit of the Coanda demonstration through mere design. I will conduct testing regerds to which design is best for demonstrating the Coanda effect. What I will do, I take my first failed design, create a new design that has more form (such as a bowl) and more dynamic flow, and test which design creates the most lift by utilizing the coanda effect. Using an electronic massing scale such as the one in this video, I will conduct three trials of each design to see whether a decrease in mass is relative to the amount of lift created, just as the concept demonstrated in the video. I will post my results and make conclusions based on which design can best demonstrate the coanda effect through lift and how can the design by manipulated for greater, future uses.

Week3 Narrative
''This section is pending --- I need to get my calculations and charts organized!!! I already have them but I need to get them posted.'' 303428mwatson (talk) 20:59, 13 March 2012 (UTC)

My Fourth task
We are a whole week behind on the entire process. So our team has to move forward as quickly as possible. As we fully leave the testing and theory phase of the project, It is time to put our research into application by creating a fully function vehicle consisting of two carboard tubes that will be connected to two battery operated air pumps that are usually used in order to inflate inflatable beds. These pumps will blow air through their respective tubes and excreet air for specified slits in the tube with the intention of the air flowing about the form of the tube and onto a surface. The purpose of this is to manipulate the Coanda effect such that a vehicle can move down a specific path.

The materials needed in the constuction of this final design are
 * Cardboard tubes, roughly 1 inch in diameter.
 * Two battery operated air pumps, we have one, but I have neglected to ask the professor to order one that is similar.
 * An AC/DC battery, to provide an efficient power supply that will be able to emit a powerful stream of air.
 * A black wooden board, one that is light in mass.
 * Reversalbe wheels, such as the ones seen on the legs of office chairs for smooth manuvering.

There are a couple of problems that we identified in the development of this design
 * The influence of weight and friction - just as I mentioned above, it takes a powerful stream of air, to put the object in motion, but it wont take much to keep it in motion, as per 'Newton's Second Law'.
 * The strain on AC/DC batteries could ruin it - we previosly tested our first design and it appears as though the battery immediately got overheated, which can ruin the battery. It started to emit a "burning" smell, which I believe was going to cause the battery to explode, or at least spark a fire.

What we must do to work around these problems
 * Take caution in testing
 * Use a AC/DC that will not require a substantial amount of energy, which having just the right amount of air pressure such that the rolling platform is able to move.

WE NEED THIS!!! This is what Chima has, but we need another in order to make the final design.

Summary of actual work over fourth weekend
In prepaation to launch the second part of our project, I am attempting to expedite and finalize construction of the slot-wing Coanda project. What I am doing in order to bring the first part of this semester's project to a close is buying sheet metal so that I am able to create the awning design blades as well as the curved awning blade for the slot wing project. We have to move along with the final design of the slot wing Coanda project. I anticipate that the final design will consist of...

 * The wooden platform
 * The wheels
 * The two air pumps
 * Outstanding power supply (AC battey)
 * COMPLETED slot-wing designs

What I now intend to do is purchase sheet metal in preparation of designing propellor blades for the Coanda hovercraft, our second Coanda project. It will require me to figure out possible power supplies for the hovercraft. We previously tested basic "blades" made of balsawood, which we expected that will at least redirect the air flow outside of the tube. This proved to be a complete misfire.

Week4 Narrative
The problems that we encountred when utililing balsawood is that it is way too thin; it breaks easily and is dynamically incapable of redirecting air streams whose pressure is in mass qualitity. I tried to cover the balsawood in aluminim foil so that it may have a much more sturdy design; but this was to no avail as well. Just as in the below image, balsa wood was proven a non reliable material in which to make a blade that is strong enough the direct flows of air.

The failure of the "balsawood" blade prompted me to purchase two sheets of aluminum sheet metal from Lowe's. I believe that since aluminum is highly malleable material, that I may be able to cut components of what will be the curved "awning" blade and soder them together to get a unique design. To reiterate, the curved awning blade will be crafted from cut peiced of aluminim sheet metal and will be welded together in order to make a decent blade. Two of the problems that I most likely will encounter in pursuit of making these blades are that, (1) the blades will not be big, so detail is critical. (2) The curve must demonstrate a figure that conforms most with the form of the tube. I will have to make two of them in order to move towards completion of the project.

Lastly, I finally managed to complete the final testing of the research design portion of the project. In this video, I was able to conclude through the failure of the previous designs is that the Coanda effect is moreso freeform and is not dependent of elaborade design, it is a priciple that happens as an effect of physical science. The primary reason for the failures of the revamped designs is that (1) their new design was considerably heavy, and would require much more air pressure other than from a blow dryer to force it out of its static state. (2) The air pressure emitted from the blow dryer was simply not enough to produce lift. However, when I removed the lower chassis of the revamped design (like in the second half of the aforementioned video), the air steam was strong enough to make the bowl incision lift (just a small bit), and gain momentum.

Using the arduino board, and control multiple outputs on the board to control motors to move the robot arm.

My First Task
How to use arduino board to control several servo motors and once.

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

Over the weekend I had planned to use the arduino board and the motor shield with the stepper motor. But I couldn't get the my computer to communicate with the arduino board.

Week1 Narrative
Tell a detailed story describing what you did for your team over the weekend.

My Second Task
Record what you are planning on doing for the team during the second weekend.

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

Week2 Narrative
Tell a detailed story describing what you did for your team over the weekend.

My Third task
Record what you are planning on doing for the team during the third weekend.

Summary of actual work over third weekend
Over the third weekend I worked on getting the stepper motors running so we could control the movement of the arm to have it function as if it was an elephant trunk. Also to come up with a way to control the pressure valve for on/off vacuum suction.

Week3 Narrative
I Found info on how to wire the stepper motor atStepper motor survey to find out which wires are what. After wiring it up properly I wanted to find a good sketch in the Arduinos examples section for stepper motors that would best suit our needs for the motor functions. But couldn't really find any after trying out a few, so I went on Google and searched for, "Arduino Stepper Motors" and found stepper motor sketch for arduino. Using the sketch they had for stepper motors I found I was able to control what types of steps ie.... double step, single step, and micro step, and also control the speeds. The single/double steps seemed to work the smoothest, also we will only be running at low speeds for each motor, and whether or not the motor is rotating forwards and backwards.

I know its Tuesday, but I just came up with a great idea for the pressure release on the vacuum! What we should do is use a servo motor and have a crescent shaped piece of plastic on it and have a hole in the tubing from the air vacuum and have it rotate forward and backwards to cover and uncover the hole and cover the hole to relieve pressure.

My Fourth task
Over my fourth week I plan on finding the exact movements for each motor to move the arm where exactly we want it to be. Also to finish making 2 more Motor setups to run the wire to the arm and move the arm around. I need help finding a Rubber stopper for this, I searched home depot couldn't find one! This week I will search around class for one. But if you guys have any ideas of where one could be let me know!

Summary of actual work over fourth weekend
This weekend I stuck with what I was going to originally do which was to create another stepper motor mount.

Week4 Narrative
Over the weekend I worked with the stepper motor mounts for the robot arm. After messing around with the wiring for the stepper motor i had to re-strip them because they weren't making good contact with the m1 and m2 ports, but from there on it was smooth.I currently have one that was built by a previous class, here is a video i made of it in action and what we plan on doing with it, Stepper Motor Mount. For the second one ive built started off with these materials the wheel and the metal bar I had to cut out of a printer rest of the parts where from home depot and some scrap wood. Figured the rubber wheel would be perfect for a replacement of the current rubber stopper on the original motor mount. When I first started screwing the brackets in for the stepper motor the wood kept splitting so I found a thicker and softer piece of wood to use and it worked out. Once I had the motor attached, I had to cut the metal bar from the printer with a saw which would hold the wheels and also drilled holes into the bracket to hold the bar with the wheel guide.Second stepper motor mount

Write problem/project Goal
A more sturdy robot arm configuration must be built to pick up, move, and set down objects. It also must have interchangeable hands between fin ray and coffee ground.

My First Task
Design a valve that can be controlled by a motor to allow and restrict vacuum flow.

Summary of actual work over first weekend
My work over the break was in no way different than my original task.

Week1 Narrative
I began my weekend using an idea with a wheel which controls the valve itself. The problem I had was that it is difficult to move a wheel forward and backward using only a string attached to a motor. I decided I needed a valve that would close by itself and could be opened. So I decided to use an air blowing nozzle that is spring loaded. By using a pulley it can be opened and then once tension is released it will close on its own. A 90 degree extension on the lever will allow downward pull to control the flow. I believe this will work well and be very inexpensive.

My Second Task
For the second week my task will be to build and test a model of the coffee grind robot end effector.

Summary of actual work over second weekend
My actual work over the weekend stayed on track with what I had set out to do, building the hand. But I was also struck by an idea which combines both the fin ray and the coffee grind hands. It is a hybrid of both that combines both of their gripping power. I may look into this once my original goal is met.

Week2 Narrative
The actual work I did this weekend was directly on track with my original goal. Using some parts I picked up from Lowe's: 2" coupling, 2"bushing, Sink drain with threads, blow gun nozzle, and some birthday balloons, I was somewhat successful. After putting them all together I hooked it up to the vacuum where I discovered a few problems. First of all my balloon was to small and was too constricting to get a good wrap on most objects as seen in :[|Coffee Grind Robot Hand]. Which I hope to fix by getting a bigger balloon. Next once I let off the trigger of the blow gun nozzle there was still a vacuum. So I need to come up with some kind of pressure relief valve.

My Third task
My third task is actually a combination of many tasks. First of all try and fix the problems previously stated I was having with the coffee grind hand. I will try and find a better balloon replacement and I will research and develop and pressure relief system. But also I will look into our method of suspending the hands in a fashion that is interchangeable, sturdy, and again very inexpensive.

Summary of actual work over third weekend
Over the third week my focus was on the original tasks. Which were increasing the gripping power of the hand itself and concocting a plan that to suspend this in mid air. However, I did not get a chance to look very far into the pressure relief valve configuration. This is because I felt I needed to know how my fellow teammate planned to control the original vacuum valve first.

Week3 Narrative
Over the third week I tried several different combinations to try and achieve better results. I went to party city and got the next two sizes of balloons bigger that I could find. Which were the 12" and the 36". Also I decided I would try and use a fine sand called Berkeley springs finely grated sand in replacement for the coffee grinds. I tried both coffee and sand in each of the new sized balloons and got some great results. I found the 36" balloons were way too big and not effective whatsoever, I wouldn't recommend using them, but the 12" balloons showed improvement. The sand proved to be especially effective vs the coffee : [|End Effector Round 2]. I also derived a method of attaching the hand to the wires controlled by the motors. It is very simple, but I feel like using some large hose clamps to a threaded bushing would be sufficient.

My Fourth task
My fourth task will include more work with the coffee grind hand. When playing around with it I found I am losing vacuum because of a faulty seal somewhere so I will look into this. Next will be a lot of work. Including making the table and adding my work to my teammates work to have a hopefully completely function ending model. To add my work I will have to create the attachment for the hand and use some wood working skills to create the base.

Summary of actual work over fourth weekend
What I worked on for the fourth week was right along the same lines as what I had planned. I needed to find a way to keep a better seal within the hand. But I am having a lot of difficulty.

Week4 Narrative
The problem with the suction is one that I honestly should have realized sooner. But the fact that I have realized this is still good. Now the problem seems to be attacking me from several different angles. I believe that the problem could lie just in the threaded portion of the drain itself. But after using Teflon tape I did not get quite the results I would like. So my angle of this week was the try and design a method of changing out the balloons in a secured fashioned drain. To do this I noticed in the center of the cross hairs at the top of the drain is a threaded hole. So I could use a tube with threads to hold the balloon in place. Just make it so that the balloon could be fashioned to the top and then screw the tube into place. This way it will be more securely fashioned into place.: [|End Effector Round 3] The problem with this is that I am having trouble finding exactly what I need as a piece. I have found that the size thread i need is a 7/16", but fitting that would work only come in different sizes. To take care of this I thought maybe I could drill the hole out and fasten a nut to the top of the cross hair region. But the hole is already very thin so if i do this I am afraid it will be way to easy to break. The other thing that jumped out at me recently is that it may not only be the threads. It could be that the shape of the drain does not work well with the balloon. Pressing a piece of PVC onto a balloon creates a really good seal I have noticed. So I thought maybe if I put a piece of PVC and extend it downward in the drain for the vacuum to be created. With this, however, the balloon tends to be sucked up into the pipe and could result in a rupture. So possibly if I put some screen over the pipe it could solve all of my problems. Which I will soon find out.

Write problem/project Goal
Construct a remote controlled boat that can fire bb's and compete in competitions

My First Task
1. Research boat designs and properties

2. Research motor's and begin researching how to program the arduino to control them

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

Work followed according to the plan.

Week1 Narrative
Tell a detailed story describing what you did for your team over the weekend.

For the most part, researched ways to program the arduino and attach various devices that can be used to control the motor as well as the rotary cannon platform. Since arduino is all open source software and coding, their tutorial was very easy to obtain. It seems the easiest way to control the rotation of a platform would actually just be another motor (stepper motor knob or servo http://arduino.cc/en/Tutorial/MotorKnob or http://arduino.cc/en/Tutorial/Sweep respectively). Wiring the motors is very easy in and of itself, remote controlling it would be a different story. Still searching for a way to attach say an R/C cars mechanisms to the arduino and set that whole thing up.

My Second Task
Record what you are planning on doing for the team during the second weekend.

1. Look into rc hack tutorial

2. Continue searching for the necessary parts for vehicle weapon system

3. Find a way to hook up arduino to pull trigger mechanism (probably an actuator or even still another motor)

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

For the most part, everything followed on plan. Decided for now that a remote controlled firing system is too many steps away

Week2 Narrative
Tell a detailed story describing what you did for your team over the weekend.

So over the weekend, I realized that in order to test out wiring the remote control system to the arduino would probably require an arduino and a remote control chip. Neither of which I brought home with me. So basically I had to just looked into finding parts for the boats weapon system. I contacted the leader of my airsoft team, who told me that he would take a look and see if he had any spare/broken rifles. Waiting for his response. Basically all we would need (if we dont want to just mount the entire rifle on the boat)is the rifles gearbox, possibly the barrel, and some device to hold the bbs. Generally gearboxes in a rifle chassis are spring fed, which means they feed upward. Airsoft Electric Gun (AEG) magazines have a wheel at the bottom which you wind which scoops bbs from the reservoir in the magazine into the lip where the magazine is connected to the gearbox (pictures to come). This can be problematic on a mobile vehicle because we will have no way of winding it so we will most likely rig a gravity fed reservoir like in a paintball gun. Also, for the current moment we have decided that we should go step by step instead of jumping far ahead. I think before we can try to get the arduino to pull the trigger mechanism on command via remote, we should first just get it to fire anything. In this case, we will most likely use a stepper motor and have the device fire in intervals.

My Third task
Record what you are planning on doing for the team during the third weekend.

1. Program the stepper motor

2. Hook up the stepper motor to some sort of trigger mechanism

Still waiting on a response from my arms dealer man. If only i had money, then i could just buy my own.

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

Found an excellent graphic on how an AEG gearbox works

Week3 Narrative
Tell a detailed story describing what you did for your team over the weekend.

For the most part drew up a design for the boats weapon system. I will upload a picture later when my computer decides it wants to start working again (right now im on my tablet). Basically if were pressed for space we can just use the internals specifically the gearbox and the barrel. It fill need to be gravity fed so we can find one that is top fed or we can just invert a regular gearbox. Started looking for some potential guns. Links later when i get a real computer

Update: Ideally we would have something like this or this but seriously look at those price tags. Need to find cheaper ones, while not sacrificing power and the needed specs (size, power, gearbox, etc)

My Fourth task
Record what you are planning on doing for the team during the final weekend of project work.

1. Work on the servo motor and arduino and program it to rotate

2. Research possible AEG's for purchase

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

Servo motor/arduino combo would not function correctly. Believed to be a result of wiring/soldering problems. Will fix on Wednesday when I have access to the lab or find another arduino motor combo

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

Attempted to continue working with the stepper motor. It worked back when we were in the lab but when i tried it again at home it did not work. Before when i plugged in the arduino the motor would turn on. Now it just sits there. It think the problem is with the motor or the wiring because when i tried the blink command it still works. Probably the soldering broke off or something. Im going to try to solder it back on wednesday and see if it helps. So since that had to wait i spent some more time looking into airsoft guns. Found a few good possibilities relatively cheap and compact models (mp5/7 models are preferable but g36c models or commando models are also acceptable. Must have metal gearbox though).

Update: Found 2 that would be nice, and relatively cheap and this and this (this one may be best as it is the most compact, the cheapest, and the same if not higher power)

Update: Didnt know how to upload pictures to wiki so I put them here (check it out sometime, its the frontpage of reddit)

I need to figure out the best way to manage the existing setup of the robot, then edit the bots end effector so that it becomes easily disabled.

My First Task
I will Create interchangeable parts alternating from the Fin Ray claw to the Coffee Grinds gripper.

Summary of actual work over first weekend
We decided to make two arms one for the coffee grinds gripper and another for the fin ray claw, this is different than the first plan which was to create the two interchangeable parts for the robot arm.

Week1 Narrative
During the weekend I did a lot of research on the different ways engineers created their own robot end effectors in order to help me discover the best way to create the parts needed to improve our own robot end effector. After looking up the different types of end effectors made I came to a conclusion that the only way to maintain the parts already constructed and have both claw and balloon gripper functioning with the same controlling system would be to make another arm that's separate from the other. I said this because if I tried to build upon the current arm created from glued and taped-up peaces of legos, its functioning and efficiency level will decrease. I then created sketches of a new arm that could be attached to the robot.

My Second Task
During the period of this week I will design and create a new claw for the robot using the same simple designs used in constructing the current claw.

Summary of actual work over second weekend
Nothing I did differed then I planned this week. I'm still making the robot claw using metal claws and a worm gear DC motor to move the claws.

To construct a remote control boat that can shoot BBs and navigate through the water.

My First Task
I will research how to write remote control programs as well as how to hack the television remote to control the boat.

Summary of actual work over first weekend
I had planned to actually discover a way to hack the remote wonder, but I could not find adequate information.

Week1 Narrative
I attempted to install the program for the remote wonder on my computer, but after many tries, it would not comply. Though the program installed, it would not receive the signal from the remote. I gave up on the remote and decided that it would be much more efficient to use a regular R/C receiver and transmitter; This way more time can be spent on the functions of the model boat rather than the controls.

My Second Task
I am going to brainstorm possible ways of affixing the power source to the boat.

Write problem/project Goal
Hack car remote to use voice command on phone to unlock vehicle

My First Task
What I will do is research the OBD and how the OBD for the Ford Expedition works.

Summary of actual work over first weekend
What I did was that I ended up looking through videos on youtube on how exactly an obd works and all the different functions it has. I just wanted to familiarize myself with it so that when I came back to meet with my group we had a wide range of ideas on how to push the project forward. I also did use search engines and read articles on it.

Week1 Narrative
Over the weekend I searched exactly all different parts of the inside of a car and it's computer. To be exact I researched the on board diagnostics (OBD) and how the ECU works. To be specific I also searched how to make sure to connect the OBD adapter to the car we are going to use, and how the wifi connects to Torque, a specific app that we are thinking about using. After all the reading I did what I went to next was youtube video's because I am a visual learner so seeing others do it helps me imagine how I am going to make mines different. At the end I kept on repeating this process until I felt completely comfortable with it.

My Second Task
I am going to research code for the car we are using the specific ford expedition 2002 and how to control the system with this code

Summary of actual work over second weekend
What I actually did was researched this and found a few pages that helped me find coding for obd and videos on youtube.

Week2 Narrative
I googled things for the OBD for the Toyota Corolla since we decided to switch cars. One of the webpages I found was http://www.obd-codes.com/trouble_codes/toyota/ and http://www.samarins.com/diagnose/checkengine.html which just tells a little more detail of what your car actually reads out when you plug in the OBD. Some of the coding did help, however we still need to get a functioning OBD for our car to actually read to begin hacking.

My Third task
Going to go to home depot and pick up a few things so that we have all the right tools we need and see if it is that the OBD doesn't work with the model car we are using, or that we need a OBD-II.

Summary of actual work over third weekend
I did end up going to home depot to take pictures of the different materials we needed. I searched codes for the obd that we could use as well as finding other ways to actually get the obd to work.

Week3 Narrative
Now since we got the obd-II I researched how to use this with our car hack project. We decided not to do the wifi connection to hack the car anymore because it gave us too much trouble. Instead what we are doing is using an arduino from class and plug in the OBD adapter to then plug in the obd to the car. The arduino will then be connected to the laptop where we installed the program Parallel Desktop and then we read off exact codes. This will put it in HTML coding instead of the regular "00901,etc" type of coding which is much better for us to read and figure out.

If you are interested in repeating the project but using wifi still these quick demos shows you how to power it. http://www.youtube.com/watch?v=oxn9mnvNzvY http://www.youtube.com/watch?v=EnPx4opR7o4

To read more about ECU's here is a link http://auto.howstuffworks.com/under-the-hood/trends-innovations/car-computer1.htm

My Fourth task
For this last week I will get into the car's computer system and read off the coding to see if I can get the RPM

Summary of actual work over fourth weekend
What is different than what I actually planned is that I wanted to be able to read off the RPM but unfortunately we didn't read that level. On the other hand I got to read off codes from the car with the materials we got from the class as well as outside.

Week4 Narrative
This last week I got our Arduino from class and the new OBD-II that was purchased. I needed to test this so what I ended up doing was going out to the car with all needed materials. Laptop, OBD-II, and arduino. Since we decided to work on a mac and not a windows laptop it really did help that the Scantool.net was downloaded because this specific obd only reads off codes based off of windows. What this program was able to do was to convert the mac into a windows and power it off from there. The first step into reading off these codes was one connecting the OBD to the car underneath the steering wheel. Once there was a signal from the OBD which is just the red light flashing on then this was the signal to go. We put the keys in the ignition but still didn't start the car. From this I just connected to the OBD to the arduino and on the other side the of the arduino I used the usb cable to connect to the mac. Once I connected it to the mac I opened up the program ScanTool.net. When the program successfully ran David turned on the car so that it can begin to read off codes. This is where all of us were able to read off codes from our car. We got to read initial flow rate, instantaneous rate, mpg, load value= 19.2%, timing advance= 14.0 degrees, air flow rate= 0.4 lb/min, the car's throttle which in this case was 0.780V and the average 3.52Hz. From this program we can see that reading off codes from this car is limitless. I also researched different blogs on how to read off codes from this specific toyota corrola but I didn't get very far. The problem was that the majority of car hacking pages that I found was from makes of ford and chevy the most.

Write problem/project Goal
To design and construct a wind turbine.

My First Task
Get a car 12 volt DC 110 volt AC inverter and locate a suitable motor to use as generator.

Summary of actual work over first weekend
I planned on coming up with a full design of our wind turbine. It turns out I had a lot more research ahead of me before i could do that. So I started experimenting with different motors to be used as a generator. I determined that I was going to need to find a much bigger motor then was available in the shop. The plan over the weekend was to go to a junk yard and utilize the motor from a radiator fan.

Week1 Narrative
Over the weekend my group and I went to the junk yard and found a radiator fan the would make a great foundation for our wind turbine. The motor in the fan was able to generate 4 volts from just blowing air at it with an air compressor under no load. So I believe there will be some useable energy to harness here.

My Second Task
In the second week of the project I want to develop a way to charge a cell phone with the radiator fan by blowing air at the fan blades and causing it to spin.

Summary of actual work over second weekend
In week two i wanted to go bigger scale then what i was working with in week one. In week 2 I wanted to take the radiator fan and motor to charge a cell phone. In this week I discovered that there are a lot more problems to look over such as adding resistors to the circuit to regulate the power being produced. So in this week I decided to scale down the wind turbine to a smaller motor with smaller fan.

Week2 Narrative
In week 2 I decided I needed to start much smaller then was i was dreaming up in my head. So I begun to design a much smaller prototype. Instead of setting an unachievable goal for myself I decided to light up a single LED light. The first design I build was a small motor with a small fan on the motor shaft. I wired and LED directly to the motor in a simple series circuit. The problem I faced was that there was nothing to regulate the power to the LED to I was over powering the LED and burning it out. So next instead of just playing around trying to light up the LED I started to record data of the voltage and current outputs of the wind turbine. After that I used an online calculator to calculate the kind of resistor I would need to protect the LED. Now my circuit was a series circuit with a 2 volt LED and a 100 ohm resister. Next I wanted to built a mount and base to hold the wind turbine so I didn't have to hold it with my hand anymore. I took a cat litter box and mounted a PVC pipe with the wind turbine on top into the box.

My Third task
Record what you are planning on doing for the team during the third weekend.

Summary of actual work over third weekend
In week three I planned on doing small scale testing. throughout the week I started small but moved my way up to full scale. This week mainly for md consisted of myself building the wind turbine and blades and my other two team members working on test circuits.

Week3 Narrative
I did a lot of work in week three I worked three days for about 4 hours each, so I am going to break down what I did in week 3 day by day.

3/7/12 I started off this day by checking on an epoxy bond I made on a bigger fan that was to be mounted on our prototype motor. The biggest challenge I faced with getting the bigger fan on the motor was to make sure I get in on straight so that it spins balanced. So I had a hole in the center on the fan that was slightly smaller then the motor shaft, so I heated the motor shaft with a torch so it would melt the plastic to slide on and make a perfect fit. however this did not work as well as I hoped and the fan was very unbalanced, but being impatience I decided to test it like that any way instead of making it better. As I begun to test the voltage output of the motor with the bigger fan the voltage output was very low only .5 volts because the bigger fan does not spin as fast. So since this voltage was not suffecient enough to light an LED I decided to scale up to using a radiator fan motor as a generator. the first thing I did with the bigger motor was find a new way to mount it. In the shop there was a metal pipe in a concrete base that would work perfectly so I went to work mounting the motor to the top of it. After spending about a half an hour mounting it on top I was very excited to mount the fan to it. I then became very frustrated when I found that I had not measured correctly and it would not fit so I have to spend another half an hour remounting the motor so the fan would fit. Next just out of curoscity I wanted to see if the bigger fan from the radiator would spin in natural wind. The fan was however was to small to generate the torque needed to spin the motor. for testing purposes I used a leaf blower to generate a higher voltage this bigger wind turbine with the leaf blower was able to generate 7.9 volts. Pretty impressive I thought enough to light a couple LEDs or to charge the battery in a cell phone.

3/8/12 While my other group members worked with test circuits to collect more data from the wind turbine I came up with a task for myself. I really wanted much bigger blades that would spin in real natural wind. So I made blades that were 2.5 ft long in order to make a 5 ft diameter fan. I developed a very simple way of doing this by cutting a cardboard tube into froths so they could be mounted in opposite directions on a hub. My plan for the next day was to make a hub to mount them to.

3/9/12 The last day of the week I spent all my time making the bigger fan. I needed to make a hub to mount the blades to. I started to look around the shop for something that was a circle that would work. I couldn't find anything so I decided a square piece of wood would work. I mounted all four of my blades to the hub then drilled a hole in the center of the hub for the bolt on the motor to go through. After that I took it outside to see if it would spin and to my surprise it spun relatively fast in very low wind speeds. I wanted to make it spin faster by blowing the leaf blower at it but the fan blades flexed to much causing them to hit the pole.

My Fourth task
In week four I will continue work with larger wind turbine blades to try and produce useable power with natural wind.

Summary of actual work over fourth weekend
In week four I planned on harnessing natural wind to generate useable power. This is the same as what I actually did however I side not succeed in my goal.

Week4 Narrative
In week four I sought to accomplish my goal by making more efficient wind turbine blades that would spin faster in natural wind.

The first step in making the new blades was that I needed to come up with a design the would work better then the first ones I made in week 3. The first problem I addressed is that the bigger blades although were very large and spun in very low wind speeds the speed of them was limited due to their size and that they were too flexible because of there length. I decided not only do I need to rethink the length but also the material. So I decided make them half the length then the previous design and out of PVC instead of cardboard. Since I wes making this change I had another problem and that was how can I get the blades to generate enough torque to spin in low speed wind just like the larger ones. I came up with two solutions the first would be that I would double the amount of blades so instead of 4 blades on a square hub I was gonna have 8 blades on an octagonal shaped hub. Next I needed a way to make the smaller blades generate the same torque as the bigger blades. So I came up with a way to do this which seemed counter intuitive at first because it involved decreasing the surface area of the blades. But what this design did actually allowed me to do is harness a mechanical advantage by funneling the wind to the tips of the blades furthest from the center of rotation. The way I achieved this was by cutting a diagonal line across the blade so the wind would funnel down to the tip. This was different from the bigger blades that had the same curve the whole way along them.

The beginning preliminary cut on the new blades.

After diagonal cut was made.

Full blade assembly

Full blade assembly.

Blade assembly mounted on motor

Video of the new blades spinning http://www.youtube.com/watch?v=74-k8h8T634&feature=youtu.be

After having the new blades assembled I needed to test them in natural wind. The problem I had though was the day I was working on it there was no wind outside so to simulate the wind I went indoors and resorted to using the leaf blower, although the leaf blower only simulates very high rates of wind. After testing and finding that these new blades only generated 6.5volts I needed to rethink the generator I was using. Throughout this whole project I have been fighting one major problem. That is that I have been attempting to generate power but the motor I have been using to generate power is designed to work at high RPM low voltage. So in order to actually make this work I need a better motor that is designed to work with a high voltage and low RPM. So for the next 4 week project I will continue to focus on wind turbine but my main goal will be to find a motor that will work well as a generator.

Coanda Effect

Write problem/project Goal
We're trying to create a rotating platform that uses the coanda effect

My First Task
I'm going research more about the way the Helicopters can operate with the Coanda effect

Summary of actual work over first weekend
The the first physical task I did beside research is trying to get the old coanda project, and that was a complete failure, the air just seemed to flow around and ant random. while i was playing with the project i remembered my teammate Marcus did some simple test with coanda, and i remember him saying that is all based on design, the old coanda project had the wind flow left adn down, and air doesn't curve like that, all the coanda test Marcus did the air was flow straight up o down. so i come up with the assumption that I need to come up with a whole new design.

Week1 Narrative
Over the weekend i was to go home and see if i could get the first coanda project to work. what i did was set the project of a table and used a hair dryer to blow air throw both ends of the tubes, the air would just bow right throw the tubes and wouldn't make the platform rotate, so seemed one side of the tubes, and blew air throw them, seemed the opposite side and blow air threw it. nether attempt were successful...

My Second Task
Find new tubes we can use for a new design for the coanda project

Summary of actual work over second weekend
Why i planned to do at first is use CD player to make an object hover, but i couldn't find a proper CD player to use. But what i did find is two air pumps that I can probably use for the project air pumps

The one on the right is cordless, but doesnt generate enough air to move the platform the one of the right is more powerful but needs an outlet, In the end i think we'll use both an just a attach an external battery to the cordless to boost it's power

Week2 Narrative
I really didn't do much, i was just playing around with the air pumps i had found

Wind Turbine

Write problem/project Goal
To design and construct a functional scalar wind turbine
 * | Funtional Wind Turbine Prototype

My First Task
To charge and test batteries that will be used for power storage and to research inverter designs and create a schematic for an inverter.

Summary of actual work over first week
I had planned on charging a 12v battery with a trickle charger. The trickle charger was unsuccessful in charging the battery. I had also planned on creating an inverter schematic. I was able to recreate a schematic but I was not able to understand exactly how an inverter works. To fully grasp the concept I must learn how exactly a transistor works.

Week1 Narrative
I began drawing up ideas for the Turbine design. I analyzed contemporary designs both professionally manufactured and home-made to get a starting point. Then I referenced available tools and materials to come up with a strong, effective, simple design.

My Second Task
To test more batteries and to disassemble a computer fan which I believe is from a power supply.

Summary of actual work over second week
All batteries tested (two 12V and one 6V) and successfully charged. I had a minor mishap with the fan when I took it apart.

Week2 Narrative
I disassembled a small computer fan in order to scavenge the fan blades. During the removal of the shaft I cracked a fan blade. I proceeded to disconnect the DC motor from the fan blades to understand how to get the next one apart because this set of blades was broken. I roughly documented my steps at home; I planned on disassembling another on Tuesday with a full detailed tutorial to show to my team. The reasoning behind my detailed tutorial following my initial attempt is so that I understand how to properly take it apart without breaking any blades during the detailed documentation.

My Third task
So far the plan is to research a way to have two separate LED's turn on at different amperages. For example, when our motor is only producing 2V a yellow LED is emitting and when the generator is producing 3.86V (max V from generator spun with an air compressor @ 100PSI-tank pressure and ~35PSI-output pressure) a second LED is emitting as well or when the HI-V is being produced the LOW-V LED is off. I am not sure which is possible or which is less complicated. The idea is still very rough, hopefully through some thorough research and progression through my Principles of Electrical Circuits text, I may arrive at a solution. I have been drawing up circuit diagrams for my goal: I am postponing the idea of a HI-V and a LOW-V LED display. I have transferred my focus to producing a parallel circuit that uses a pull down resister to regulate voltage and current to my LED and on the other leg of the circuit using the amperage to charge a battery. With 150mA I should be capable of charging a small 1.6V NiCd battery or a lithium ion battery (a cell phone battery). In order to charge a cell phone battery I will take a Micro-USB connector, sever the wire and direct wire it to my circuit (assuming that I have the proper resistance within the circuit; this is achievable by deriving my resistor value by calculating my desired Voltage and Amperage).

Summary of actual work over third week
The original plan fell through completely because I destroyed our miniature prototype fan blades during a test. The blades came off the crankshaft during the test for two reasons: first, because I had not fully secured the blades to the shaft; second, because I applied maximum (35) PSI from an air compressor. Instead I had to scale up our project design incorporating the DC motor we scavenged from a radiator fan during week 1. Because I had to redesign a whole new prototype, I have postponed my LED circuit testing. I have also had to retest motor output using a leaf blower instead of compressed air. Instead of redesigning a base and shaft I scavenged a pipe cemented into a plastic bin and used that for the main shaft and support.

Week3 Narrative
I designed new motor mount for larger motor on the new shaft. My plan is to use a dremel with a cutting wheel to make slits equal to the fins on the motor, use a sanding wheel to create a cup to sit the motor in, and drill two opposing holes and run a bolt through the pipe and the motor.

 * Because I am working with a larger motor with higher voltage and current output I have redesigned my test circuit to include greater resistance so that we are not flowing too much current through the diode. In order to calculate the resistance necessary for the circuit I had to do some LED testing to determine their optimum voltage and current, turn on voltage, and what current exceeds the desired range.

 * During a test of the 12V DC-Motor, using a 1HP electric leaf blower, we were able to produce 8.1V maximum. Using this information and an LED Calculator I was able to determine that my circuit would need 330 Ohms total resistance. From that I was able to design a simple LED circuit with 330 Ohms resistance incorporating an ammeter and voltmeter to measure our motors output. During the creation of the circuit, I was unable to find a 330 Ohm resistor so I had to improvise by soldering a 220 Ohm resistor and a 110 Ohm resister in series. Finally, I attached the test circuit to the wire harness that was part of the DC-Motor assembly. Next step was to test the circuit while attached to the generator. I decided to use ambient wind speed and see if I could get usable power. During the test I was unable to get a voltage or amperage measurement. I later realized that my circuit resistance was so much that the amount of current created from the wind was not great enough to forward bias the diode. This caused my circuit to be open and the result was no Amp or Volt readings. Next, I decided to use the 1HP leaf blower in addition to the ambient wind speeds. Before I could take a measurement, the additional wind pressure caused the long cardboard blades to collide with the shaft. I propose that I cut the blades in half and increase our number of blades to 8.

 * Next, I planned on using a 12V cigarette USB adapter to charge a cell phone using a traditional USB to Mini-USB cable. In order to do so I severed the cables leading to the adapter and soldered them directly to the wire harness. During the test, I was unable to produce a charge at maximum output with two leaf blowers. I tested the circuit directly with a variable power supply. During the test I heard a large popping noise. I checked the fuse to see if it was the source of the noise, it was not. I'm still not sure what it was but I did discover that I had reverse wired the circuit from the harness to the adapter.

My Fourth task
Over the next week I plan on testing, finishing, and implementing my charging circuit as well as testing my LED voltage detector circuit. Also, I plan on redesigning and constructing a new fan. Lastly, I will record a video tutorial on how to disassemble a PC fan (will include my documented steps from earlier in the project) and a video tutorial on disassembling a radiator fan and motor.

Summary of actual work over fourth week
I had originally planned on rewiring the wire harness and USB adapter circuit. The adapter circuitry was destroyed resulting from the reverse biasing of a capacitor. This caused the capacitor to burst and was the source of the loud popping noise during the initial test. I eliminated the possibility of fuse failure because the fuse was still measuring voltage, proving that it remained a closed circuit. I was unable to find an identical PC fan so I've decided not to create a video tutorial. Also, the PC fan is obsolete within our new design specifications. Lastly, I have successfully created and tested an LED voltage detector circuit. I am working on a way to implement the design onto the main chassis of the turbine.

Week4 Narrative

 * In an attempt to reduce time spent soldering and hard wiring my circuits together, I began experimenting with breadboards. Since I am not familiar with wiring circuits on breadboards I began with some simple tests. First, I wired a single LED using 4 jumpers. One from the power source to the positive column, one from the power source to the negative column, then a positive and negative to power and return. I later realized that the same task can be accomplished using only two leads, directly from source to row. Now that I have understood how to supply power via jumpers on a breadboard, I tried wiring two LEDs in parallel. To connect them in parallel I set my positive row on row 15 and my negative (return) on row 18. Then I attached the LED's Anode to the positive row (15) in column A and the cathode on the negative row (18) in column A. The next LED I set had a 1 column 3 column gap on the board so its anode was in row 15 column E and its cathode was in row 18 column E. Remembering that series circuits divide voltage and parallel circuits divide current, using a variable power supply I was able to see that the circuit operated at 1.8V at 40mA. This means that the current doubled in order to power both LEDs meaning that the circuit was indeed parallel. Next, I wired three LEDs in series and I tiered each one cathode to anode. This circuit took 5.4V at 20mA to power all three LEDs. Because the voltage was divided, the circuit was wired in series.

 * Next, I placed a 1 Ohm resistor in parallel between my LEDs causing the first LED1 to turn off and LED2 to remain on. This is because the current flows to the path of least resistance and the resistor caused the current to bypass LED1 because it was not forward-biased and therefor had greater resistance. In another test, I had three LED's wired in series, when a parallel resistor is introduced between LED2 and LED3, only LED3 turns on. Using the same series LEDs, if the resistor is introduced between LEDs 1 and 2, both 2 and 3 remain on.
 * ParallelLEDCircuits.jpg
 * Continuing on my train of thought, I decided to wire my side-by-side test circuits together in parallel and see the outcome. Only LED 1-2 was functioning. This illustrates the same concept as the first two tests using a parallel resistor. This lead me to the conclusion that I would need an initial pull down resistor before the LEDs to draw enough current to forward bias each leg of my circuit.

 * Using the same LED Calculator as before, I calculated my initial test circuits resistor values:

I would need a 100 Ohm resistor in order to drop the voltage down to 1.8V. I will also need an initial pull down to draw current through the initial LED. Then using a variable power supply set to 2.7V, I lit the LED. This was a fast test in order to check my resistors and LEDs.
 * I've added another leg on to the original circuit in an attempt to regulate the turn on of the LEDs at varying voltages. I attached the positive and negative leads on the breadboard to the variable power supply. First, I increased the current just enough to allow voltage flow, then I adjusted the voltage regulator until my first diode turned on. Then I switched the display to amps and measured the current flow. Next, I switched the display back to volts and adjusted the voltage regulator until the second diode turned on. The circuit worked! I've recorded the results below.

Because this double-LED circuit is designed to divide 3.2 volts, I must increase the number of LEDs to 3 in order to handle 6V. I may even need to include a fourth LED.

 * I've added another leg and noticed the same pattern of turn on as with two. What is interesting, and possibly incorrect, is my data. I've noticed that the middle LED requires 17mA to turn on while the third only requires 5.2mA. I may have misread the meter so I will have to retest the circuit and make sure my data is accurate.

 * Another interesting characteristic of my circuit is that it is only capable of soft-switching. Meaning that the LEDs do not turn on at full brightness, they fade in and out depending on the voltage. My next goal is to solder a hard-wired LED voltage detector on to the wire harness and connect it to the wind turbine generator.
