Write problem/project Goal
Create a Wind Tunnel for other projects to test aerodynamics.

My First Task
Mount motor in wind tunnel part. Look for Straws!

Summary of actual work over first weekend
Found Some Straws and Started to find the materials for mounting the motor in the propeller housing.

Week1 Narrative
The straws we need: 8.5 inch Straws 200 for $1.90

My Second Task
Mounting Motor, Refining control scheme, Run motor off new power supply

Summary of actual work over second weekend

 * Attached Motor to inside housing
 * Trouble shot Motor and power supply, got it to run correctly off new power supply
 * Tested, then removed new control scheme.

Week2 Narrative
The wooden bar in the center of the motor housing was put in and the I assisted in mounting the motor to that bar.
 * Picture here: [[File:BrushlessMotorMountedInHousing.jpg]]

Next the wiring was sorted out and the entire housing can function, Testing soon followed, but the ESC was not functioning properly. Even with the use of the new power supply, the Motor spun backwards before starting a very slow spin, then stopping, then starting again.
 * Picture: [[File:WireAttachmentInMotorHousing.jpg]]

The new control interface was added, with a switch so a speed could be selected and the motor turned off without having to change the poteniometer position.
 * Picture:[[File:NewArduinoControlSchemeForMotor.jpg]]

Since the motor was not working, the was taken out to ensure this was not the problem that needed to be trouble shot.

The issue first arose, and normal power supplies were being used. Switching to another more durable and more consistent supply allowed for the elimination of the possibility the problem originated in the power supply. This took some work as the wiring was not compatible and a wire needed to be made and connected.

After the wiring was sorted and the new control scheme reverted to the older one that was sure to work, the Motor still did not spin up correctly, and also did not emit beeps when first plugged in and before it started, though it still flashed the red light.

Once I had realized that the problems arose after we disconnected the motor from the ESC to mount it, and it blew air in the opposite direction briefly before this behavior, I reversed the wire connection between the ESC and the motor, fixing the problem as this had happened when I reconnected the motor and ESC after mounting.

My Third task
Better Shroud in Motor Housing

Summary of actual work over third weekend

Wind Tunnel/Howard Community College/Spring 2012/BJ560

Problem Statement
To create a usable desktop Wind Tunnel to be used in an engineering lab to test object's aerodynamics.

Team Members

 * Michael Walker
 * Justin Jones

Summary
The project advanced in creating the wind tunnel. The Basic wooden structure was fabricated and put together. The main wooden components being the floor of the test chamber, the motor and fan housing, and the box that is responsible for lamination of the airflow. The Motor was hooked up to a reliable power supply, and runs effectively with the Arduino and potentiometer setup. The major wooden components have been assembled using wood screws and Goop glue. Plexiglass was cut and shaped for the test section.

Story
The project started with a working motor on an unstable mount, a square box for holding the straws to create laminar flow,and the control components for the motor running off of a separate power supply.

The first project push was getting the arduino to run off the power from the ESC. This eliminated many issued with powering the arduino and fixed many problems associated with power supplies using different grounding methods, such as one having a floating ground and the other having an earth ground. The latter differences can cause "dirty" or "noisy" signals, causing improper operation possibly damaging components.

Next a square motor shroud was created to encase the fan motor and propeller. During this phase the laminar box and the motor shroud were sealed. The wooden base for the major wind tunnel component was cut. A bar to mount the motor in the shroud was screwed into place.

Next the Motor was removed from it's unstable mount and mounted in the fan shroud. The ESC and wires were connected, placed, and mounted in the fan shroud. A hot wire anemometer component was created by removing the glass from a regular light bulb.

The three pieces of the wind tunnel, the laminar box, the tunnel base, and the fan shroud were connected together with sealant glue. a reliable power supply was also located and is used to run the motor/ESC through 12v and ground, and the hot wire anemometer through 5v and ground.

Decision List
No formally recorded Decisions were made.

Material List

 * Adruino Uno
 * Potentiometer and Wires
 * Hextronik HXT 80 Electronic Speed Controller
 * Brushless Motor
 * Converted computer power supply
 * 1/2" 4'x3' plywood for construction
 * 1/8" Plexiglass
 * Wood Screws
 * Goop sealant glue
 * Wood Glue
 * 2"x2" 10" wooden bar

Software List

 * Arduino Uno Compiler Software
 * Google Chrome
 * Microsoft Office Word

Time
Approximately 45 Hours of work were preformed on the project.

Tutorials
No Tutorials were made, but some were useful:
 * Arduino ESC Programming

Next Steps

 * Complete the Plexiglass Part of the wind tunnel
 * Fill Rear section with straws to create laminar flow
 * Tweak Arduino control to user preferences
 * Configure and calibrate hot wire anemometer
 * Inside rectangular ran shroud, use sheet metal to create a circular fan shrowd

Write problem/project Goal
To build a small wind tunnel which can test the aerodynamics of objects.

My First Task
Over the first weekend it is going to be my job to finish the compressor and diffuser as well as begin working on the test section of the wind tunnel.

Summary of actual work over first weekend
Over the first weekend it was intention to simply make the base for the entire wind tunnel by taking a sheet of particle board and making multiple cuts to it to form the shapes necessary for the perimeters set forth by the group. This changed because there was a few problems that I ran into which altered my path to completing the task. This included measurement problems, improper equipment, and human error which I had to take into account afterwards and correct.

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.

Over the next weekend it will be my responsibility to cut the plexiglass for the test section and begin research on the wind speed monitor and the device we will use to monitor air flow over objects.

Summary of actual work over second weekend
Over the second weekend, I only planned on making the feet for the wind tunnel. However, I realized that on the mainframe I mis-measured one of the cuts so I had to also cut out two wedges to compensate for my mistake.

Week2 Narrative
Tell a detailed story describing what you did for your team over the weekend. First I brainstormed Ideas for how to attach the mainframe to the other pieces. I realized that I could not nail or screw them on due to the length of the board. I also realized that glue would not be a good compromise because it would be a loose bond capable of bending and breaking. Because of these issues I decided the best Idea would be to attach them with feet on the bottom that overlap the edges. Not only would this secure the pieces in place but also it would give us the opportunity to place some sort of anti-vibration compound on the bottoms of the feet so that the wind tunnel does not vibrate or move due to the power of the fan. I then decided to take a sheet of 1/2 inch ply wood and cut out 10 feet for the wind tunnel. Each foot is about 1"x2". 4 will be placed on each end of the windtunnel in a box shape with two in the middle of the wind tunnel. I then had to factor in my mistake on the measurements for the mainframe into my work. So, I cut out two wedges which could be adhered onto the edge of the mainframe making a tight seal. I measured out two wedges which were about 1 inch wide and angled down to a minute width. I then cut these with a circular saw.

My Third task
My third task will be to start cutting the plexiglass and finding a way to cover the feet so that there is no vibrations from the fan.

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

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

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
Over the fourth week I simply thought I would have to repair the missing wedge on the wind tunnel and attach the anemometer along with beginning the standardization of the device. however, instead I found myself beginning to cut the plexi glass and attaching it to the wind tunnel.

Week4 Narrative
Took a piece of 1/2 inch plywood and cut out a wedge to attach to the windtunnel. Applied wood glue and attached the piece to the windtunnel. Then applied a vice to bond the wood.

Anemometer -found a light bulb that had a working filament -Heated the bulb with a heat gun thoroughly for 2 minutes then placed the bulb in a cup of cold water This effectively shattered the glass but kept the filament in tact. -I then dried the bulb _after it dried I soldered on two wires to the filament. One to ground and one to the current so That it could be hooked up to a power source. -then I hooked up the filament to an external power supply and attached a meter to the filament to read the current. - to find wind speed readings I blew on the filament. This changes the temperature of the filament and increases the current. -The anemometer still needs to be standardized so that specific measurements for speed can be attained.

Plexi-glass -I took sheets of 1/8th inch plexi glass and viced them to the table. -I then marked out my measurements with a dry erase marker. -Following that step I scored along my marks with a box cutter. - Then I placed the scored edge along the edge of the table and snapped the plexiglass. -Sometimes this did not work and left uneven edges and shards, however after practice the edges became clean. -To attach the plexi-glass I took a rabbit and then grooved the edges of the wind tunnel so that I could insert the plexi glass along with liquid nail compound to bond the plexi-glass to the wood.

Engineering Projects/Power projects/Howard Community College/Spring2012/p3550K

Problem Statement
The main purpose is to make LAB power supplies like other power supply projects.

The specific goals of this project are:

 * 1. Figuring out how this power supply works

 * 2. Converting its outputs in order to become usable in LAB as a power supply

Team Members

 * Keyvan

Summary
Tried to add binding posts to a variety of power supplies, but none worked as well as the PC power supply.

Poster
''Put a graphic in wikimedia, include the graphic here or link to it here. The graphic should be suitable for creating a traditional project poster.''

Story
Checked power supply of old HP plotter, power supply of laser printer, and some other random power supplies. Could not take them apart and get them to work ... when disconnecting them from the original equipment something was lost that disables them. I tried putting loads on the what appeared to be the output power lines, but they still did not work. They are all switching power supplies which are delicate. Some were in the rain outside for a while.

Decision List
The only decision made was to give up on everything but pc power supplies.

Material List
Need the following tools:
 * wire stripper
 * multimeter
 * soldering iron and solder
 * drill gun

For each power supply need:
 * 5 binding posts
 * 1 power cord
 * 10 ohm power resistor
 * LED
 * 360 ohm resistor to protect LED
 * quarter roll of electricians tape
 * switch

Time
7 hours

Tutorials
Tutorials were created in previous projects, none new here.

Next Steps
There are about thirty pc power supplies that can be converted in the Lab as of 5/10/12. The next step is to create an assembly line with the following stations:

1. Test ... see if fan spins, if it spins it will work. If fan does not spin, strip green, red and two black wires. Hook green to black, then test voltage between red and the other black. If there is 5 volts, it will work.

2. Drill holes

3. Cut and strip off all the wires, leave room to twist them all together and then stuff the wires back into the power supply and put the lids on.

4. Solder the same colored wires together.

5. Insert binding posts and solder wire to binding posts. Solder one wire of each color to a binding post.

6. Put switch in the green wire, put led and 360 ohm in series between the gray and an unused black wire.

7. Hook power resistor up to discharge the capacitors.

May want to rotate the drilling the holes. This can get tiring. Need to invest in some sharp bits and using drilling oil with the drill press.

Write problem/project Goal
The main purpose is to make LAB power supplies like other power supply projects.

The specific goals of this project are:

 * 1. Figuring out how this power supply works

 * 2. Converting its outputs in order to become usable in LAB as a power supply

My First Task
This stuff is the most complicated power supply that I've ever worked. I expect it to produce lots of current because of its size. Its size indicates that it had taken apart from a big machine, and it has a big and complicated circuit. As I observed, its outputs have computer-like sockets. I should take apart it and try to recognize wires and their powers, then connect them to binding posts in order to get power from them easily.

Summary of actual work over first weekend
I opened up the power supplies lid. I is made up of two electrical boards: power supply and a complicated board containing lots of ICs. I tested the voltage of its switch. I realized the switch works properly. I followed wires from the power supply board to the other board. I cut and striped them. Then, I measured their voltages; I tested any combinations of two wires. I got no power. Again, I tested the voltage of the switch. I figured out it does not have power, neither works. I guess the complicated board give orders to the power supply board, so because I've cut the wires, even the switch does not work. After that, I started tracing the input power on the power supply board. I traced it until the half way between input wire and outputs, but it became so complicated. I gave up. Next, I made a tutorial for creating a test protocol for ATX power supplies. Here is its link: How to make a test protocol for ATX power supplies

Week1 Narrative
I opened up the lid, this big guy is made up of two parts, power supply and another board with lots of ICs; it looks like main board of a computer.

After that, I tested the switch again. I realized that the switch does not work anymore. I guess that the main board gives orders to the power supply board to make power. Now because the connection between the two boards does not exist, the power supply board also does not work. Then, I remove the switch and shorted the input power to the board and started tracing the power. I followed the power until the half way between input and outputs. I passed a couple of capacitors and get to ICs which I lost the trace; therefore, I finally gave up.

I got to create a tutorial for making a test protocol for ATX power supplies. Here is the tutorial:

How to make a test protocol for ATX power supplies

My Second Task
I have to do some research to determine that if there is a way to fix it again and get power from the power supply board.

Summary of actual work over second weekend
After trying many things to get power from the power supply, it was confirmed that the power supply board must be connected to the electrical board to make power. Therefore, I, with a little difficulties, figured out which power supply's wires had been connected to which slots on the electrical board before I cut them off. And I put them back. I measured their voltages; their maximum voltage is 1.6 volt although under the slots it's written that it produces 24 volts. So, I guess the electrical or the power supply board had been damaged which causes this shortage of voltage. I also found out that the electrical board has several outputs, so I measured their voltage and I got 1.6, 0.6, and 0.3 volts.

Week2 Narrative
First, I tried to figure out in what order the wires from power supply board were connected to this slot.

My Third task
I am going to drill 3 holes and put binding posts into them in order to get power from the system easily.

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

Talk:Analysis of variance

Sorry, I'm not a statistician, and don't really feel qualified to edit here, but I am unhappy about classing ANOVA as a technique of multivariate statistics. Isn't it helpful to keep the clear distinction between multivariate situations and multifactorial situations? ANOVA is a superb example of a multifactorial technique, where perhaps we have only measured one dependent variable, but we've done so with multiple treatments (experimental factors) on which our measured variable depends. This contrasts with multivariate experiments where we have measured many (perhaps hundreds or thousands) of variables, but may have done so in only two treatments (control and treated). The distinction isn't just a matter of words. The two situations are very different, and carry different risks (although there are parallels in obscure situations). In multifactorial experiments we don't have the curse of dimensionality, but we do have the problem that multiple pairwise comparisons would be likely to create false-positive results. In multivariate world we know that some combination of our measured variables is bound to correlate (purely by chance) with our treatment, which complicates interpretation. Sorry to be fussy about this distinction... 81.141.32.251 22:30, 12 April 2012 (UTC)

Problem Statement
Build a stand for the bridge

Team Members

 * Javiereduturcios
 * Mir07
 * Engsihn

Summary
Initially we agreed to make a case for the bridge, and decided to design the bridge in 123d. We also started thinking of what would be the best weight system for the bridge. We researched on linear actuators, however they were not the best choice due to the fact that there were too expensive and their specifications did not match up to what we had in mind. Linear actuators are designed to move a certain distance and their force varies depending on the distance. Therefore we decided to work with some that was like a tension testing machine.

Story
The Main idea of this project was to create a case or house for the bridge so that when the weight is applied to the bridge it does not go all over the place when it explodes. We first started on the design part of the case. There were some issues as to the size of the bridge, however we just decided on the design part first and not worried about the scale of the actual bridge case. We chose 123d is our primary designing software mainly because its free and easy to use. There were also tutorials for 123d in case we got stuck on something. The housing for the bridge was the first part of project, the second part involved the weight system that would create tension on the bottom of the bridge in order to break it. It would also tell us how much weight was applied to make the bridge break. The weight system would be comprised of either linear actuators or some other tension testing machine. One of the team members was responsible for gathering data on the bridge,the casing and the weight system. The other team member was in charge of researching and designing and case for the bridge in 123d and the last member was responsible for coming up with the best way for creating the weight system.

Decision List

 * I. Case for the bridge

1) Design:            - Create a design for the bridge    2)  Software: - can use any 3D package - 123D 3) weight system:              -linear actuators               -tension testing maching

Material List

 * 1. Software is free however the tension testing machine may range from $200 to $2000.
 * 2. Linear actuators or tension testing machine will be required for this project.

Software List
123D software from 123dapp.com is used for designing the case for the bridge

Time
10 Hours

Tutorials
Tutorial on how to download 123D software
 * MakerBot/How to download 123D

Next Steps
Next step is to find the software that goes along with the tension testing machine and build the case for the bridge either using wood or metal.

Write problem/project Goal
Build a piston system to pull apart the spaghetti bridge.

My First Task
Design a stand for the bridge, kind of a housing for the bridge so that the debris from the bridge can be contained when its pulled apart

Summary of actual work over first weekend
My task was to design a kind of a housing or a case in which the bridge can be put in so that it does not go all over the place when it breaks from the weight applied to it from the bottom.I thought of using Maya2012 for the design, but decided to use 123D instead because of its ease of use and because of its friendly user interface(UI).

Week1 Narrative
The following steps will show my process from downloading to creating a design in 123d software.

Sotware Required
1) 123D

Tutorial
How to download 123d This tutorial shows how to get stated with 123D.

 * MakerBot/How to download 123D

My Second Task
Research on Linear actuators, they are mechanisms used to provide a linear motion from a rotating motor. This can be used to create the weight system that pulls on the bridge.

Summary of actual work over second weekend
In Week two I decided that I would research on Linear actuators. This is one of the important mechanisms that could be used to provide linear motion that would be used as a weight system creating tension to break the bridge.

Week2 Narrative
I researched on actuators and stumbled upon this website http://www.trossenrobotics.com/linear-actuators.aspx, on this website there are a lot of actuators, however the one I was looking for was not available. The problems I encountered with linear actuators were

 * 1) No USB Port To connect to the computer
 * 2) It does not hold 1000N
 * 3) No rod

The linear actuators provided on this website did not match for what I was looking for because the stroke was not 100N. I found another website http://progressiveautomations.com/ on it I found “Linear Actuators (PA-02)” http://progressiveautomations.com/linear-actuators-c-8.html?osCsid=eb2b995d4efefeb44b421162fb61b060. Some positive and negative things about this actuator Negative:
 * 1. It does not hold 1000N
 * 2. It is very expensive
 * 3. It does not have a usb port to be able to connect to a computer

Positive:
 * 1. It has a rod that allows it to be connected to the wood on the bridge

Another actuator I found on the same website looked a little promising, the PA-02-10-400 http://progressiveautomations.com/linear-actuators-linear-actuator-stroke-size-force-400-lbs-speed-059sec-p-58.html

Positive:
 * 1. It has a rod that can be easily connected

Negative:
 * 1. It only holds 400lbs

After researching some actuators I went on to youtube and looked up spaghetti Bridge world Championship 2009 videos. http://www.youtube.com/watch?v=_pejHjPJlcE. I tried to see if I was able to see the brand of the linear actuators, but the video barely showed the linear actuator. I looked on some other videos but I was not able to see what kind of actuators were used and how they were able to use the linear actuator to show the weight on the computer. There were other videos that had a different weight system, most of them used sand or other types of weight to break the bridge, but the only problem with that is carrying that much weight is problematic and not accurate enough. http://www.youtube.com/watch?v=fhdx2HTH7to&feature=related I was not able to find the perfect actuator but I have some idea as what kind of actuator would be right for the bridge project. It has to be some thing that can be controlled with andurio so that it would be easy to control the weight on the bridge.

My Third task
My next step will be to look for linear actuators that can be control by arduino and redesign the bridge in 123D.

Summary of actual work over third weekend
In Week two I researched linear actuators but they were not suited for the bridge, and they were expensive and also they did not have an easy way to program them. In week three I then stated to research on tension testing machines for the weight system for the bridge.

Week3 Narrative
I researched on tension testing machines and found this website http://www.sciencebuddies.org/science-fair-projects/project_ideas/MatlSci_StressStrainStrength_h005.shtml, which seemed promising in providing some information about tension testing machines. It even showed the formula that is used for calculating tension.

 * 1. Stress = force/cross-sectional area
 * 2. Strain = change in length/original length

This formula could be used in creating a program that could go along with the tension system to actually measure the weight applied to the bridge. However I think that this kind of software could easily be found without the need of it ever being coded by myself.

These kinds of machines can easily be programmed and therefore would be able to tell how much pressure is being applied to the bridge.

I found a tension testing machine called - Zeus ultimo. However I could not find the price for it, I found helpful specs that could aid when actually purchasing the machine.
 * 1.Computer Bases Tensile Testing Machine - Zeus Ultimo
 * 2.Capacity : 250 Kgf ; Least Count : 100 gm
 * 3.Type : Floor standing ; C.R.E. Type.
 * 4.Grip to Grip Separation : Minimum 25mm and Maximum 700mm.
 * 5.Two sets supplied with the machine.
 * 6.Cross Head Speed : 50mm - 500mm / min. With Servo Motor Variable Speed.
 * 7.Speed Control : Through Graphic user interface PC. Cross
 * 8.Head Travel Length : Overall travel length 800mm without Grips.
 * 9.Load Sensor : Universal "S" Type / Pancake Type.
 * 10.Load Sensor Accuracy : +0.5% of the Load Cell capacity.
 * 11.Calibrated by NPL approved proving ring dynamometers.
 * 12.Load Sensor Sensing : Auto - detect / sensing through advance electronics. Electronic Auto-Zero
 * 13.Over Load / Travel Safety : Auto stop through software : 10% above load cell capacity / Built in

System Controls : Advance Micro - controller systems From my research I was able to find some website that offer the tension machine and the price ranges $200 to $2000 depending on the quality of the product
 * 1.http://www.alibaba.com/product-gs/491054528/Universal_Material_Tensile_Testing_Machine.html?s=p

Problem Statement
Our goal is to create a program that uses images scanned from a webcam to track the attendance of students coming into the Engineering room.

Team Members

Summary
Our first goal for the project was to learn how to use the software Yawcam and Picasa. After watching tutorials on the programs we decided to split the project into two, one member would work on the webcam and the other would work with the face recognition software. Installing and setting up the webcam was fairly simple, but the settings proved to be the big issue. We needed to adjust the settings just right so it wouldn't take too few or too much pictures whenever it captured a motion. Once we decided on the adjustment we wanted, we set up the webcam in the engineering room to collect as much image data as we can get before moving on to the software section. After our first test, the images were not very good, so we had to adjust the camera location and angle. We placed the camera at the front of the room and mounted it to the wall. We then decided to keep testing the camera to find the right placement for the camera location. Once we find the best location, we plan on shifting our focus to the face recognition software.

Story
For this project we decided to split the project into to parts, one member will test the camera and the other will test the face recognition software. For the webcam, we used the YawCam software and a generic webcam provided to us by our professor. For the face recognition, we used Picasa. We also tested several Webcam programs to make sure we had a user friendly program. The only one that work fairly well was iSPY, but we ran into an issue where only one camera would work at a time, so we decided that we should stick to YawCam to avoid getting side tracked. To test the webcam, we placed it at different locations throughout the engineering room and left it to take pictures for a day. We then went back everyday to make adjusts depending on the outcome. If the camera took to few pictures, we adjusted the capture image rate and lower the sensitivity of the camera. If the camera wasn't in the right angle, we moved it to a new location. The first location pointed direct at the door, but it only captured one side of the face. The second location was at a 45 degree angle from the door, but we had to move it because too many people were using the area so we couldn't get a good shot of people entering the room. We then decided to mount the camera to a wall mount and place it in the front of the room pointing down towards the front door. This way we would be free of any obstructions and we would have a good angle on the door. Because it took so long for use to get any pictures, we did get to use Picasa very much ad it will most likely be the next step for the project to move forward.

Decision List
For this project we decided to split the project into two parts. One member worked on the webcam setup and the other member worked on the face recognition software.

Write problem/project Goal
The project goal is to design a webcam that will take the attendance of students as they enter the engineering room.

My First Task
My first task will be to learn how to use YAWCAM

I also watched several tutorials on YouTube:

YawCam Tutorial

YawCam Tutorial 2

YawCam Tutorial 3

Summary of actual work over first weekend
This week I setup a webcam using YawCam to take pictures of any motion it detected in a designated area. The camera was able to take pictures, but it took too many pictures. I lowered the tolerance level, but this time it took too few pictures. After testing the tolerance level, I attempted to adjust the zoom setting using YawCam, but all the settings were blacked out. I will need to find a program that will adjust the zoom settings on my Webcam.

Week1 Narrative
This week, I did further testing with the Yawcam by setting up a designated area for the webcam to detect motion, take a picture, and store it in a specific folder. After I set up the folders and basic settings, I began testing the accuracy and speed of the motion detection. By adjusting the tolerance level, I was able to control how often the camera will detect motion. By adjusting the speed, I was able to control how often the camera took a picture. But I was unable to get an optimal setting because I didn't have enough motion traffic to test all the settings. In order to get an optimal tolerance level I will need to set the camera some place where there is a lot of moving traffic. After adjusting the settings, I worked on correcting the zoom, but all the zoom settings were blanked out and I could make any adjustments. I will probably need to find a new program or find a specific program for the webcam.

My Second Task
My second task will be to find a program that can control the zoom function of the webcam. I will also need to test the tolerance level of the webcam in a place where there is a lot of people constantly moving.

Summary of actual work over second weekend
I searched online for a starting point to get the zoom function to work, but after further research the camera itself does not have a zoom function. So in order for the camera to take accurate pictures, it will need to be placed relatively close to its target area.

Week2 Narrative
I searched through YawCam's Forums, but was not able to find the exact settings to control the zoom. YawCam does have a camera control setting, but it seems like the camera I'm using doesn't have any zoom functions. I tried looking for a serial number and manufacturer, but couldn't find anything on the webcam to get me started. Being unable to find the serial number for the webcam, I can only assume that the webcam is fixed at its current zoom. After further research I found the camera at WebCam, but it's only a generic camera without any zoom control. I also searched |&filterName=platform=Windows CNET and found several webcam programs, but many of them were similar to YawCam or I couldn't get them to install because they were outdated.

My Third task
My third task will be to setup the camera in the engineering room to test out the sensitivity and tolerance level of the camera.

Summary of actual work over third weekend
This week I worked on setting up multiple webcams to take pictures from different angles/rooms and uploading them to a single folder.

Week3 Narrative
The webcam I'm using lacks zoom control so I decided to add multiple cameras to be placed in different locations to compensate for the lack on controls on the webcam. I searched online and found iSPY. This program runs similar to YawCam, but it allows the user to setup multiple cameras in different locations. The user is able to view all the cameras at once. After I installed the program, I was only able to get one camera to work. I tried to add a camera manually through the iSPY program, but I kept running into the issue of one camera recording while the others remained blank. I tried running both Yawcam and ispy together, but I ran into the same problem, only one camera would work despite running two separate programs. I can only conclude that this issue is a operating system problem. I checked the iSPY forums and found that I wasn't the only one with the multiple camera issue. I decided to search online and found a tutorial from the makers of iSPY, however it didn't provide any solution to my problem. I also read through the help section and discovered that I can run a webcam on another computer and connect to it through IP.

My Fourth task
I final task is to get two cameras working through IP

Week4 Activities
This week I decided against using iSPY and continued using YawCam. I setup the WebCam in the engineering room and left it on overnight to test if I needed to keep or change the settings on the camera. I checked on the camaera and found that I will need to make some adjustments to get better quality pictures.

Week4 Narrative
I was unable to fix the dual camera issue, so to make better use of my time, I went back to using YawCam. Although I have tested the camera outside of the engineering room, the ultimate goal was to have it working in the classroom. So I setup the webcam on one of the computers near the door in class and left it on overnight to see the what kind of pictures it would take. I came in the next morning and found that the camera took a lot of pictures, but some of pictures didn't have anyone in them, some were blurry, and others only had partial images. To fix the issue I adjusted the settings to take a 5 pictures every 1000ms, improved the image quality, and mounted the camera in a different location.

To mount the camera I used the mount off an unused IR sensor and taped the webcam to one end. I then added USB extensions to connect it to one of the computers near the front of the room. Once all the parts were connected and taped together, I mounted the webcam to the front wall and pointed the webcam down towards the front door. Once the web cam was mounted to the wall I setup the camera to take pictures over the weekend to test the picture quality and location. After the weekend I checked on the outcome and found that YawCam was taking was taking a picture every second, so I turned off the option to take images without motion detect and set YawCam to only take a picture when it detected motion. The camera was able to take good pictures of people, so I'll leave the camera where it is for now.

Summary
We came up with an arch but that arch broke, and it was too unstable. We have a strong hanger design. First we used a decision matrix to decide which design of the arch would work better. We decided that the single-single arch would work out the best. We started to put together the arch but we realized that it would just go straight up in the air, so we had to find the angle at which the noodles would go around the arch. Then we had to make them that angle, it took awhile so we created a board that would hold the noodles so we can sand multiple noodles at once at the same angle. And then we ran out of time.

Story
For the start of the project we all came up with a design and did a 3d drawing of it, then we split the work up by having one person figure out how to do the hangers another building the arc and another helping the 2 out. The obsticles were getting the right angle, a;so when building the arc getting it to settle and nt fall while the apoxy dried in the time it took to dry and become a glue holding things togethor. The testing that was done was getting the calculation for the angle and then checking to make sure it is the right angle.Also we tested the first arc that was not altered just pasta glued to pasta and it broke under 1 pound of stress. the informal decessions that were made were what to start first which turned out to be the arc. The assumptions were that the ideas would work and everyone would do their part, everyone did their part and the test without apoxy looks like the pasta will now work making an arc that is strong and stable.So the results are that the pasta needs tgo have some of the angle talen off to make a barc with maximum pasta toughing more pasta.

Write problem/project Goal
To make an arch for the bridge.

My First Task
To create an arch.

Summary of actual work over first weekend
It was difficult to make the arch without knowing the dimensions of it.

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

My Second Task
Draw an arch on big piece of paper to draw where hangers should go.

Summary of actual work over second weekend
I wasn't able to draw an arch on a piece of paper because I didn't have the dimensions.

My Third task
My third task is to create some clamps for the end of the hangers so we can add tension when we attach the hangers.

Summary of actual work over third weekend
I was having trouble coming up with a different designs for the hanger strechter.

Week3 Narrative
I designed a stretcher for the hangers but still need to make them to see which will work better. I came up with using balsa wood to create the clamp because regular wood would break the spaghetti, when balsa wood would just form around it. Then I had to come up with something that would spread out the pressure or else the balsa wood would flatten out. I came up with either putting normal wood on the top and bottom or making the clamp out of normal wood but then lining the inside with balsa wood.

My Fourth task
I need to make these two different style of clamps--to stretch the hangers--and test out which will work better.

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

Problem
First attempts had little design. The team built, tried, assumed too heavy, made lighter. No design, no measurement of weight, no computation and physical location of center of mass, no theory of flight, no testing of lift.

Fall 2014: Blimps are rare and extremely expensive. Need an affordable product that can be used for same purposes as a blimp and more. Can be used for constant surveillance for weather and/or traffic, military purposes, and for wireless internet services that hovers wherever you go.

Conceive
Fall 2014: Build an airplane that can successfully stay in the air for over 30 seconds and only be powered by a rubber band. Eligible to compete in the Free Flight competition.
 * Build an airplane to compete in a Free flight competition.
 * video of competition

Design
Actually design the airplane on a computer with drawing software using some established technique.

Test lift using the air handling system within a building big rigging a balance similar to the Wright brothers from the ceiling.

Fall 2014
The first design incorporated a flat wing made out of a wooden coffee stirrer frame and covered with plastic wrap, the propeller was also made out of wooden coffee stirrers and plastic wrap.

After Design Attempt 1, we decided that we should focus on making a working glider before putting efforts into the propeller.

No need to make a complicated Center of Gravity test. All that is needed is something to balance the plane on.
 * video showing center of gravity of model airplane
 * using fingers and friction

We created test protocols in Project 2 Week 1
 * 1) Find open area with no obstructions and minimal wind.
 * 2) Twist propeller in opposite direction of its natural spin 100 times to tighten rubber band.
 * 3) Hold plane 6 feet above ground in hands, making sure propeller doesn't start yet.
 * 4) Before throwing, let propeller start spinning.
 * 5) Throw plane by moving hand forward around 4".
 * 6) Use stopwatch to count how many seconds the plane stays in the air.
 * 7) Record other notes (nosedives, heavy tails, any propeller issues, etc.).
 * 8) Repeat test 5 times per model to make sure numbers are repeatable.

This test was revised during Project 2 Week 2 using more definite terms for "minimal wind" and the amount of time the propeller should spin before launch.

 * 1) Find open area, preferably inside where wind is not a factor.
 * 2) Twist propeller in opposite direction of its natural spin 100 times to tighten rubber band.
 * 3) Hold plane 6 feet above ground in hands, making sure propeller doesn't start yet.
 * 4) Before throwing, let propeller start spinning for 3 seconds.
 * 5) Throw plane by moving hand forward around 4".
 * 6) Use stopwatch to time how many seconds the plane stays in the air.
 * 7) Record other notes (nosedives, heavy tails, any propeller issues, etc.).
 * 8) Repeat test 5 times per model to make sure numbers are repeatable.

Lift is generated by the turning of a moving fluid. This involves curving the wing so the aft end of the wing points slightly downward, turning the air streams downward.

Implement
Build the airplane designed. Compute expected lift versus actual lift. Build wind tunnel if necessary. Build apparatus to measure lift. Compare measured versus computed center of gravity. Build apparatus to judge time, take pictures.

Supplier specializing in Free Flight kits using rubber instead of bands.

Choose to build airplanes individually and compete against one another or split up building parts of a single designed airplane, build separately, assembly together.

Used hair dryer to shrink plastic wrap.

Fall 2014
Brainstorm ideas, sketch designs, document everything, build design, build more designs, weigh all the models, narrow down and pick 1 for final presentation.

This Wikipedia page explains why a longer, higher aspect ratio (AR) wing can help gliders. Basically, a wing has the effect of a cylinder of air, with the diameter being the wingspan. If the wingspan is longer, with the same width, the amount of air the wing pushes downward is greater than with the shorter wingspan.

Materials needed:
 * Plastic wrap
 * Wooden coffee stirrers
 * Glue/adhesive (used Duco Cement)

The coffee stirrers are wooden sticks with a length of 6.875 inches and a width of 0.1875 inches.

Steps:
 * 1) Lay out plastic wrap over workspace.
 * 2) Take 2 coffee stirrers to act as the middle two sticks going long-ways and place adhesive on tips.
 * 3) Place the 4 coffee stirrers on each tip going long-ways.
 * 4) Cut 2 coffee stirrers in half.
 * 5) Glue 2 of the halves to the ends of the outer coffee stirrers to connect the lengths together.
 * 6) Take the wing lengths and mark at 1/4 of the length and 3/4 of the wing.
 * 7) Place the last two halves under the 1/4 mark and the 3/4 mark of the lengths. These act as ribs to make the wing more sturdy in crashes.
 * 8) Flip wing over.
 * 9) Wrap plastic wrap around the finished wing tight.

After noticing this, I placed a coiled spring on the front for weight. I used a pen cap as a temporary way to keep spring on.

Weight with coiled spring: 19.2g

Average flight: 1 second

Flight notes: Flew straight. No flips. Descended quickly though. Maybe too front-heavy, but better than stalling.

Though it flew longer with the heavier weight than without it, it was decided that the plane was way too heavy. Along with this, we determined that the flat shape of the wing was not producing enough lift for the velocity of the plane. Flat wing designs will not work. We considered other options for wing shapes, but it seems that the wing camber (shape) definitely needs to have a curve, with the aft end of the wing slightly curving downward.

Operate
Figure out the rules of a free flight competition. Create a mini competition and run it. Figure out the minimal competition that could be staged in 15 minutes or 2 hours for various audiences (K-12), engineering seminar.

Demo
presentation presentation fall 2014

Next Steps

 * Design in 3D CAD software
 * Build many models
 * Build balance to check lift
 * Structure a competition, figure out how to make a sanctioned competition
 * Test various model designs to the point that can predict performance

Airplane Float

Write problem/project Goal
To create an air plane that will glide in air for the longest amount of time.

My First Task
To brainstorm light weight structures to be used and design an airplane.

Summary of actual work over first weekend
My objective this week was to construct an airplane structure.

Week1 Narrative
During this week, I was looking through previous designs and structures of airplane and I found out that most of the airplane design has a winding propelling system. I figured that would be a difficult task because the propeller has to rotate at a velocity that would overcome the force of gravity that would enable it to keep it up in the air. My approach to that problem was to make a glider plane instead. I analyzed the structure of an airplane wing and how it is rounded and higher at one end and flat at the bottom.

According to Bernoulli's Principle the air on top is moving faster, the pressure on top is less. Since the air on the bottom is moving slower, the pressure on under the wing is greater. I started building the same structure for my airplane wings where the top portion of the wing is a little bit higher to have the rounded end at the top and the bottom is flat. I built my airplane with bbq sticks. I formed a rectangle, 12x6 inch in dimension and placed another bbq a little bit of the center to make the top part higher to increase the wind's velocity and decrease pressure on top and increase pressure on the bottom.

After glueing all the components together with the glue gun and glue sticks I wrapped the structure with a saran wrap to increase the surface area so that it would slowly glide down the ground. I tested the wing system by just throwing it in the air, it indeed glided and stayed in the air for about 5 seconds.

My Second Task
I next task for next week is to create a light thin body for my wing so that it will glide smoothly and not glide to randomly positions in the air

Summary of actual work over second weekend
I decided to create another airplane due to problems caused by my first airplane

Week2 Narrative
Over this weekend I decided to make another airplane because due to the previous airplane design, it was too heavy. I only created the wings last time, but after creating the body for it and gluing everything together made the whole plane too heavy and would just drop to the ground when lauched. After analyzing my airplane I believe what made it heavy was the amount of hot glue I used. So for this next airplane design I decided not to use any glue at all. My design consist of cutting slips of holes and just sliding pieces together. I first had to brainstorm which materials to use that are light weight and came up the decision to use styrofoam because it is easy to cut and it is very lightweight. So I then drew out my structure on the foam to be cut, I drew out a 14" X 3" for the body, 3" triangular rear wing, and 25" X 3" inch for the wing span. After drawing out my airplane in the styrofoam, I cut out my design with an exacto knife.

After cutting it out, the endges were a little jagged, so I smoothed out the edges with a sandpaper to have the air flow smoothly. Afterwards, I cut out a 3 inch long slit in the middle of my body to insert the wing and cut a small slit to insert the rear wing.

After assembling all my components I tested out the center of gravity and it was not right where the wing is at, so I decided to put glue two BBQ sticks at the wings to create stability and move the center of mass towards the wings.

My Third task
My next task is the test my airplane and see how long it glides and to improve upon it.

How is what you did different than what you planned? I designed a plane that is light weight made from light weight materials. Thin pieces of wood and plastic wrap. I used the propeller and rubber band system from a kit.

Week1 Narrative
Tell a detailed story describing what you did for your team over the weekend.
 * I started the project with slivers of wood.(1/18)*(1/18) by 24" and (1/8)*(3/16) by 24". I used the thicker wood as the main support for the plane. I used the thinner (1/18)*(1/18) wood for the wings due to them being lighter in weight. I cut the main frame piece to 18" and attached a propeller from a plane kit. I then created the wing structure to be 21" in length with 3" width. I used 4 pieces of wood as support beams. IMG 20120419 151103.jpg
 * I then used the thicker wood to attach the main wing to the center frame. By cutting 45 angles on the top and the bottom of the 3" pieces of wood IMG 20120419 154451.jpg.
 * I glued them together but could not match them exactly as they should be. After that I created the tail using the (1/18)*(1/18) by 24". I made the wing start as 3" then widen to 7" with a width of 2". I used the thicker wood to attach the tail wing. By cutting 45 degree cuts in the top and bottom of 3 inch piece of wood. I glued those together. Next I needed a back support to hold the rubber band. I carved a hole in the main beam and stuffed a little bit of wood into the hole with some glue. This design doesn't float well and needs have the rubber band go for longer. Maybe a more powerful propeller needs to be disdained instead of using an already made one.

After the test, the plane did a quick climb but instantly went to a nose dive. I then tested the flight with out the propeller. The current propeller system seems to have no affect to the flight.

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

 * Modify my previous design for better results. Come up with designs to a stronger propeller.

Summary of actual work over second weekend
How is what you did different than what you planned?
 * I modified my previous design but didn't come up with a new design for a propeller.

Week2 Narrative
Tell a detailed story describing what you did for your team over the weekend.
 * I took off the extra support beam that held up the wings and glued it directly to the main beam. The I found the center of balance and moved the rear wing up closer to the front wing to properly adjust it. Overall I lowered the weight and adjusted the center of balance. After test flight the plane glided a few seconds longer but still had the same issue with the propeller having no affect.

My Third task
Record what you are planning on doing for the team during the third weekend.
 * Design a propeller to help the aircraft stay up for longer.

Summary of actual work over third weekend
How is what you did different than what you planned?
 * Instead of working on a propeller I just enhanced the rubber band duration. I then made designs to fix a parachute on the top of the plan.

Week3 Narrative
Tell a detailed story describing what you did for your team over the weekend.
 * Over this weekend I came up with designs for parachutes to attach to me plane. One design had one large parachute attached to the front and back using similar material to the G.I Joe parachute using lightweight string. Realizing on large parachute would create to much drag as the plane is thrown. I moved to the idea of using smaller parachutes attached to the front and tail wing, two chutes on the front wing and larger one on the tail to make it level. I then realized that wings make block the function of the parachutes. Then I came up with the idea of using two smallish parachutes on the front of the plane and the back of the plane to level it out. There was still an issue of drag and the chutes opening when the plane is being launched. I came up with an idea of using double sided tape to attach to the frame and partial the chute. Leaving an opening on the bottom to allow it to be opened up when falling. The last thing I did was incorporate a launcher to it. I was thinking a sling shot to shoot it far into the air allowing a longer distance for the parachutes to work.

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

Summary of actual work over fourth weekend
How is what you did different than what you planned?
 * I did not create the chute mechanism but looked up propellers to buy/design.

Week4 Narrative
Tell a detailed story describing what you did for your team over the weekend.
 * The first thing I looked into is how to build one and I came across this design that can vary in design and gives step by step instructions,http://www.sciencetoymaker.org/plane/propeller.htm. On the website it also mentions a place where a person can buy different variations of propellers, http://www.kelvin.com/Merchant2/merchant.mv?Screen=CTGY&Category_Code=LRPPPR. These range around the five dollar range. I searched several different websites but the propeller construction was very similar but did not have pictures as the one provided earlier. I also was looking into what they used on the propeller and discovered they a rubber strip not rubber bands. The strip provide a longer duration of spin time especially when the strip is lubricated to provide less friction. http://www.faimodelsupply.com/ this website sells the rubber and sells kits to build your own gliders.

Write problem/project Goal
Create an arch to start testing and find a way to hold the maximum weight

My First Task
Come up with a design on how to create a arch and how to attach beams

Summary of actual work over first weekend
I created designs of different types of arches we could build and also created a tutorial of how to insert a compnent.

Week1 Narrative
I created a tutorialof how to insert a part that you have already designed into a new design so you dont have to recreate it. Simply their is a button that says insert component and you open the component you wnat to be inserted. In addition to this tutorial i created many different design options for my team to choose from. The front veiwof all the designs are the same so all all the designs are from a top veiw. The first design I created was the single archit is the simplest and lightest which is a big part of the criteria to our project but the down fall is the strength. The second design was the double archit is the 2nd lightest of all the designs and has moderatly good strength so is most likley what we are going to be building but if the team likes the other designs we can go a different direction. the next 2 designs are a little more out of the box and will be much harder to build and make work but the next design is the double- double arch. It is the heaviest and most difficult arch for us to build so probibly will not be arch we pick to build. The last design is single- singlearch design. The arch i would vote on is the double arch but my team members are create designs to and we could choose for one of those or even combine 2 designs together.

My Second Task
deside upon a fianl design and start designing it then try to start building it

Summary of actual work over second weekend
I created an arch

Week2 Narrative
i created an arch with the dementions 42" by 21" and used zeti spaghetti for the wholething and also put string threw it so it could be pulled tight to let dry and stay on the arch easier but will be easy to get out of the spaghetti.

My Third task

Write problem/project Goal
create an arch that wil hold the most wieght that it can.

My First Task
i am going to create a design for the arch.

Summary of actual work over first weekend
i did as planned since i made a 3d model of the arc that is made up of small cylinders to represent the pasta that i decided to use for my arc, it took going through pictures of pasta to decide which type to use.

Week1 Narrative
over the weekend i looked at different types of pata and decided to use the cylindrical type that is hollow and i will justglue the pieces togethor so that they stay togethor and bend to make an arc. in 123d i made the little cylinders and then i started to attach them in an arc to make our arc.

My Second Task
my second task will be o start making the arc.

Summary of actual work over second weekend
my weekend went as planned because i started to build the arc.

Week2 Narrative
Over the weekend i made the arc to the bridge and took pictures as i built the bridge i used the epoxy to glue togethor peices of penne pasta to make the arc. also i thought about how to attach the hangers to the arc and decided it would be best to glue them to the joint of the pasta to give the best structural support. Also i started to design a peice to get the angles right for the perfect bridge were every piece is touching.

My Third task
for the next weekend i will finish a design and start to make a piece to sand down the pasta.

Summary of actual work over third weekend
what was different instead of making another arc i made a holder so that we could get the pasta to the correct angle and i made some designs for the arc to get the best idea.

Week3 Narrative
over the weekend i got a piece of wood and marked spots one inch apart along a line and then drilled a hole that fit the noodles the best for a tight fit. Also i came up wit two designs one which was a block of wood with holes in it and the other with the hole that went throughit at a slight angle so i could just sand it down and know i had the right angle. The prototype that i made was to thin since if you sanded with to much force the noodles would break.

My Fourth task
for the fourth week i will continue making the noodles with the right angle and make the arc.

Summary of actual work over fourth weekend
This went as planned as far as making the noodles have the angle but i did not get to building the arc since getting the noodles to the right angle took so long.

Week4 Narrative
Over the weekend i used the board that i made to hold the noodles and sanded them down to make a slightly bigger angle by taking alittle off so it would be about 3 degess taken off. I did this for a bunch of noodles but it took a while and some broke while others had to much sanded so they would not work. So by thinking i decided that the board would be fixed if it was thicker, i started working on it but the piece of wood i was working on had already been drilled partially on the other side and i just went back to the first one and was just more careful.

Problem Statement
To program an InkJet printer so that we can integrate its mechanics in the construction of a miniature golf course obstacle.

Team Members

 * Marcus Watson
 * Chima Ezenwachi

Summary
Over the course of four weeks (the final engineering design phase), we constructed a putt-putt golf green obstacle by reverse engineering an InkJet motor that has been dismantled from an unused desktop printer. We manipulated the movements of the InkJet motor by modifying simple example Arduino programs (Motor Party), and hooking the AC supplies up to the InkJet motor. In order to achieve the ultimate goal, to attach the reverse engineered InkJet motor to the side of a pendulum such that it could swing simultaneously with the motor, we had to deliberate on several methods of which we could affix the motor to the pendulum, while considering its bulkiness in size and the weight of the pendulum being too much for the motor to try and move efficiently. Eventually, after applying elementary physical concepts, such as center of mass and rotational dynamics, we were able to mount the motor to the pendulum at a place where the weight is equal with respect to its fulcrum (the hook of the pendulum to the frame), and managed to get a swing of about 12 inches.

However, our next problem rose from the fact that the base of the frame of the pendulum measured about 30 inches in width, and the 12 inches is not sufficient enough to block any object, let alone a golf ball. The solution to which we agreed on was to attach two wooden blocks to the sides of the pendulum to make up for the lost coverage, which gained about 8 inches in coverage overall. Considering that the pendulum's swing coverage is still about 10 inches short of the entire base of the frame, we are still considering multiple solutions as to how might we able to maximize coverage of the pendulum, and ultimately program a motion detector camera to the Arduino and frame so that the pendulum can move automatically and on sight of an approaching object.

Upon receiving the project, we were a bit confused on what or objective was; however, after examining what should be done in order to move the project forward, we got right to work on writing Arduino programs to make the pendulum swing in concordance with the InkJet motor on the printer.

Marcus Watson handled a great deal of Arduino work; he was responsible for writing a script for the arduino to move back a forth, without hitting the sides of the printer chassis, which could damage either the InkJet motor, or the Arduino. Multiple tests were ran before creating an ideal program that could achieve this goal, but also provide an extra power boost to the Arduino so that the pendulum could swing farther.

Chima Ezenwachi worked on the platform that would be used to mount the InkJet chassis to the pendulum; however, it took knowledge of rotational dynamics to determine the height at which to mount the platform so that the InkJet motor could provide the best (or farthest) swing. First he had to take some measurements. At first, the printer was supposed to attact to the pendulum throw a hanging type of platform but Chima thought to create a self for the printer to sit on, so he brought in a self and to two self supports and made the self platform for the printer so it sit right next to the pendulum with plenty of space to put the Arduino and InkJet motor.

Story
Week1 - The first week dealt with deliberations among on how to begin the project; what was the purpose of the project, what technologies could be involved in order to facilitate the progress of the project; what problems facing us now need to be resolved in order to complete the project. Things moved quite slow; however, once the goal was known and established, progress picked up quickly.

Week2 - The second week started both the design and testing process. Testing of original Motor Party Arduino program, testing various power sources; decided that no new program needed to be created, rather, modification of the speed values and commands of the current program were needed. Early measurements of the pendulum, final product was envisioned and broken down for task assigning. Watson was responsible for writing a script for the Arduino to move back and forth. Ezenwachi was responsible for creating a platform that would be used to mount the InkJet chassis to the pendulum, so that it could swing simultaneously with the Arduino programmed InkJet cartridge.

Week3 - Construction of the platform to place the chassis at particular level with the center of mass of the pendulum. Took numerous measurement to try and determine center of mass. Finally got the platform built and mounted securely. Used tape to connect the InkJet cartridge to the side of pendulum. Initiated testing of swinging pendulum.

Week4 - Deliberated on possible solutions on how to get the pendulum to swing farther and cover the base of the pendulum. Modified Arduino program speed values. Came to a solution to "use what we have;" decided to tape blocks to the base of the pendulum to increase coverage of pendulum swing and provide a greater "challenge" for objects to get past the frame. Continuing to examining possible solutions on how to better hook up cartridge to the pendulum.

Decision List
Our application of physical principles in regards to pendulum dynamics were derived from this website.; however, it was through testing that we were able to determine an appropriate height for the mounting of the platform so that the InkJet chassis could connect to the pendulum.

From Simple Pendulum dynamics we were able to conclude that being able to distinguish center of mass from the fulcrum (bolt and screw), and determine weight distribution.

From this principle, we concluded that any place higher than the center of mass would result in decrease in period. Anything lower than the center of mass would require a greater length of Inkjet motor movement.

Software List
Arduino Open Source Programming Software program; used in creating and modifying Arduino programs such that the InkJet could move back and forth at certain times, certain speeds, and on certain commands. This open source program can allow you to manipulate the functions of various electronic programs.

Time
15 hours 7 minutes

Tutorials
The Arduino encoding project is being developed by 1sfoerster. We used the described process in order to hook the appropriate wires onto the Arduino. This also covers a bit about the soldering job and the encoder used to program the InkJet motor.

Next Steps
Considering that this project is made to be an obstacle course, there are various starting points from which later students can choose from. Future students could modify the current saved Arduino program to achieve maximum swing coverage of the pendulum. If they are satisfied with the current program, the next step would be to find an appropriate apparatus, besides tape, that will connect the InkJet cartridge to the pendulum; achieving this will provide a better swinging dynamic and could also increase pendulum coverage.

A really good advancement to this project would be to also modify a digital output encoder module, such as this one, and program the Arduino to respond to a domestic security motion sensor, or perhaps a webcam, such that any object that approaches the pendulum, could run a single program that could block it from passing through the frame of the pendulum.

A sound sensor may also be a good alternative to try and program. This here is the cheapest type of sound sensor. There are others; but they seem to be very expensive.

Write problem/project Goal
Create a computer program for a reverse engineered InkJet Printer in order to manipulate its movements. Utilize the InkJet motors to contol the movements of a pre mounted pendulum, which will be affixed to the frame of the pendulum such that the InkJet and pendulum can move in a simultaneous fashion, thus simulating an obstacle for a golf course.

My First Task
To try and manipulate the movements of the InkJet Printer.

Summary of actual work over first weekend
Over the course of the week, I spend a couple of hours in the Engineering laboratory trying to manipulate the movements of an InkJet motor via a Arduino Uno. It took me several atttempts to try and program the Arduino; however, I was unsuccessful. After consulting Chima, he was to identify the issues that I was enounctering with hooking up the Ardunino to the InkJet motor, and possible solutions to them. After resolving these issues, we were able to manipulate the power supply of the InkJet motor and make it move in accordance with its already set program. The InkJet moved back and forth with some mechanical resistance; however, I found it very progressive that I could manipulate the movements by changing the voltage (and moving its connector cord out of the way as needed.)

1 2 3 4

Each of these different videos are the configuation of the power supplies, AC black/red on different power arrangements of the Arduino. I learned that it is NOT beneficial to alterate the various power supplies of the InkJet in risk of wearing out the InkJet motor, or corrupting the basic functions of the Arduino. So with that being explained, I figured out that my goal was to create an appropriate Arduino program that would smoothly make the InkJet move back and forth without it hitting the far extremes of the printhead, or inducing mechanical resistance.

I am still developing a program by cutting and splicing parts of the current Motor Party Arduino program. I am able to manipulate the actions of the InkJet and the print head by testing various input and output values.

Our goal is to research and create a computer program that will not only have the InkJet move in a consise motion, but also to seek objects that will cause the InkJet motor to move the pendulum in a motion which tries to block the object from passing through the frame of the pendulum.

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

Week2 Narrative
Over the second weekend I continued to develop an Arduino program that meets the specifications I established for the behavior of the InkJet in relation to the motor. 1) It must not hit the far extremes of the printhead. 2) No mechanical resistance. 3)Must move left and/or right on command prompt. First and foremost, I must download the appropriate motor shield driver to run the Motor Party program for Arduino which I obtained from this tutorial. I had much trouble trying to syncronize the Motor shield driver with the Arduino; thus, it took a long time for the Arduino to respond to command prompts sent from my computer.

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 wrote four different programs that were all modified from the original Arduino Motor Party application.

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

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
Over this last weekend, I completed all of the Arduino programs that programs the InkJet motor, to move both right and left without hitting the railings of the InkJet chassis, and to move back and forth (the entire length of the chassis) without hitting the railings. We finally mounted the platform to the frame of the pendulum, after making measurements and determining the center of mass of the pendulum, to which an equal weight distribution would not cause such a strain on the Arduino motor, and the Inkjet. The primary issue surrounding these final steps of the project were to create enough swing in the pendulum such that the whole bottom frame of the pendulum could block an object, such as a miniature golf ball, from passing through it.

Week4 Narrative
In creating the connector piece to the pendulum, I had to use the resources then available to me. I took a small wooden block, about 1 cm thick, 2 x 4 dim., covered it with duct tape. Then I had taken a strip of duct tape, wrapped it about the pendulum while leaving a sinew of tape sticking out. I used this piece to attach the wooden block to, then wrapped another ream of duct tape around the block. I finally used some pink marking tape, to connect the wooden block to the InkJet motor; however, I used a very light ream that is strong enough not to break when the InkJet was moving the pendulum, but not strong enough that the InkJet would resist the Arduino program (in other words, I made sure not to put so much tape on the pendulum and InkJet that I wouldn't "tape down" the InkJet to its rail.

After testing all programs on the InkJet motor, I decided that it is not lack of programming that causes the InkJet to move the pendulum at such a small length; rather, it is the the tolerance of energy that the motor can withstand being exceeded because of the weight of the pendulum. In this video, the power of the InkJet motor is only enough to swing the pendulum at a gradual, but small rate. This was our problem - How could we make the pendulum swing farther (cover the base of the frame) while utilizing the same Arduino program? One solution we considered was to lower the platform that connects the InkJet motor to the pendulum to a point where weight is equally distributed along the length of the pendulum (center of mass). Reviewing this video, I realized that the reason because of the inefficient coverage of the base of the pendulum is because of the platform being mounted at such a high height, thus creating an unequal weight distribution (as seen in the video). At first, the height of the platform was too high, so I had to make my measurement again, and remember to account for the fact that the pendulum is already about 3 cm from the ground. So, Chima measured the length of the pendulum (as about 26 inches) and nailed metal holdings at about half that length( about 13 inches from bottom of pendulum). I then lowered it a bit. Testing the program again after lowering the height of the platform, the swing covered much better space, but not all the space at the base of the pendulum.

As a result of the InkJet motor not containing enough power pendulum ot getting maximum coverage, I decided that I could maximize the coverage of the pendulum frame by adding two blocks to the bottom of the pendulum. In this video, the goal is to use the two blocks to try and get the pendulum to span the entire opening at the base of the frame. However, the inkjet motor is too weak to push the weight of the pendulum to each end of the base of the frame. I had to push the InkJet motor manually. From this issue, I decided to revise the original Motor Party Arduino Program, and changed the "set.Speed" value from 3 to 6, thus increasing the speed; however, not the power of the InkJet motor. I did this in order to take advantage of the physical principle "increase speed -> increase in kinetic energy." This way, more the swing of the pendulum could cover more ground (not as much as desired), but also add a little difficulty to the function of the pendulum. By adding on these two wooden blocks, and at an angle of about 100 degrees, not only would objects need to avoid hitting the pendulum, but also not get caught in the angled bin.
