Problem Statement
Developing power supply apparatus solutions for other projects.

Converting a computer power supply to a lab power supply.

Team Members

 * Keyvan
 * Chris Nunez

Summary
Computer power supplies cost around US$30, but lab power supplies can run you $100 or more! By converting the cheap (free) ATX power supplies that can be found in any discarded computer, you can get a phenomenal lab power supply with huge current outputs, short circuit protection, and reasonably tight voltage regulation on the 5V line.

Story
We converted three ATX power supplies to LAB ones, and fortunately all of them work perfectly. Here is the detailed process:

First, the power supply should be opened. then, all wires were made shorter. Next, a 20 ohm power resistor was connected to a red and black wire. The power resistor helps to discharge capacitors, so the possibility of getting electrical shock decreases. After that, the green wire was shorted to a black wire to turn on the power supply. If you got a switch, it would be better to connect them to the switch. Next, the gray wire was connected to the Cathode of a LED, and a 360 ohm resistor was connected to the Anode of the LED while the resistor was connected to a black wire. For determining Cathode and Anode of a LED, we used the "diode" feature of a multimeter. If a multimeter is connected correctly to a LED, the LED turn on, so you can realize which leg is Cathode, or positive, and the other leg is Anode, or negative. Then, all remaining same-color wires were gathered and connected to each other; blacks, reds, oranges, yellows, and blue go with each other. The most challenging part of the project was drilling holes on the case of the power supply. It was a little difficult because we wanted to drill holes on metal. We used 2-3 different size of drills from thin to thick and used water for cooling down the drills. After drilling 6 holes, 5 for binding posts and 1 for LED, we attached binding posts to them and connected each wire to each binding post. We soldered all connections. We placed the LED to its hole and closed the power supply. Then, we labeled binding posts. Finally, we plugged it in and checked the output voltage of each binding posts by a multimeter. Black is ground; orange is 3.3 volt; red is 5 volt; yellow is 12 volt; and blue is -12 volt. We did same process for the 2 other power supplies.

We confronted several obstacles during this projected. First, we started working on one power supply, so one of us was able to take it home and work on it, and the other one had to do research about it. Therefore, from the 2nd week we decided to work on two power supplies, so both of us were able to take a power supply home over weekends. The 2nd obstacle was that we only found one 20 ohm power resistor and used it in the first power supply, so we've got to parallel two 20 ohm resistors in order to get the same resistance in the circuit for the 2nd and 3rd power supplies. The third problem was about the power supply itself. Two of our power supplies were DELL, and they had a big transformer which was attached to the top of their cases, so we got less room for our work. The 4th problem was that the LED hole of the first power supply was in the way of putting the ATX power supply together. So we had to shift the hole to another location.

When each power supply finished, we tested the output voltage of their binding posts by a multimeter. Black is ground; orange is 3.3 volt; red is 5 volt; yellow is 12 volt; and blue is -12 volt. Also, other combinations of two binding post give different voltage. For instance, 5 volt with 12 volt give 7 volt; 12 volt with -12 volt give 24 volt and so on. In addition, their LED's work properly. Two power supplies' LED turn on steady and one of them blinks.

List all formal decisions made with links to their documentation such as a decision tree or decision matrix.

1. For the first weekend, we decided that one of us take the power supply home and work on it, and the other one do some research about power supplies's safety: | working on the power supply

Doing some research

2. The 2nd week we decided to start converting another power supply while we were still working on the first one.

Start working on the 2nd power supply

Material List
An ATX power supply of any rating above 150 Watt (can be found from an obsolete computer, online, or at your local computer store) Wire cutters Needle nose pliers Drill Reamer Soldering Iron & Solder Electrical Tape Heat Shrink Tubing & Heat Gun (optional but would recommend) Binding posts LED (optional) Current limiting resistor for the LED (330 ohms)(optional, only need if adding a LED) Power resistor to load the power supply Low Wattage Switch (optional, but helps to turn on and off the output of the power supply.) Computer Power Cable

Software List
No Actual software was used besides web references.

Time
30 hours

Tutorials
Here is a good tutorial web page for converting a ATX power supply to a LAB power supply

ATX Power Supply to a Lab Power Supply Video on how to convert an ATX power supply to a Lab power supply

Next Steps
I would definitely recommend others who take this project to:

1. Solder all connections carefully. w/o soldering, wires will be easily disconnected, so the power supply will not work.

2. Use 2-3 different size of drills from thin to thick. First, make holes with the thin one and then make them bigger by the thicker one. Also, each 2 or 3 seconds, cool down the drill by oil or water. If you do not cool them down, the drills get too hot and start melting, so they lose their sharpness.

3. Use heating gun and shrink tube for covering all stripped wires and connections.

4. Be careful not to touch Capacitors or other interior parts of the power supply's board.

Problem Statement
Develop an Arduino based autopilot system for a RC Hovercraft.

Team Members

 * Josh Bers
 * Justin Jones
 * Wendell Phipps
 * Imane Badra Tate

Summary
Initially we agreed to construct a basic hovercraft from scratch. However, after a working toy hovercraft was located, the project changed directions to trying to program the hovercraft to react to sensor inputs.

Story
The project began with the group deciding to design/build a basic working hovercraft. Initially work on this hovercraft commenced with us breaking up the work between group members. The project was split into 4 parts; design, hovercraft movement coding, ESC programming, and hovercraft construction. However, between weeks 1 and 2, we were able to locate a working toy hovercraft. This pushed the project forward alot. All the group members came together to decide upon new jobs and a new direction for the project.

With a working hovercraft already available, our group decided to work on powering/controlling the hovercraft via an Arduino and various sensors in place of the RC controller's potentiometers.

New jobs were decided upon; power control, RC Hack, ESC programming, and infrared sensor programming. However after some slow progress, a few jobs were swapped, and the final project jobs were divided as follows; power control, RC Hack, infrared sensor programming, and touch sensor programming.

We got each individual job finished, but we have not gotten to make them all work with eachother yet.

Decision List
List all formal decisions made with links to their documentation such as a decision tree or decision matrix.

Material List
Materials used
 * Toy Hovercraft
 * Arduino
 * Motor Shield
 * Infrared Sensor
 * Touch Sensor
 * Soldering Iron
 * Solder
 * Camera

Software List
We used the Arduino software for tutorials for use on the RC Toy Hack, as well as creating new code to allow for additional potentiometer.

We also used 123D for preliminary design of a hovercraft.

Time
30 Hours

Tutorials
All projects create new tutorials of technical details future participants are going to want to know. They are going to be separate pages that are linked to here.

Next Steps
The next project should included fully hacking the RC Controller to control the hovercraft via the arduino. After RC Control is integrated, work should be done to replace the RC Controller input with a sensor input(infrared/touch/sonar).

The overall goal I was assigned is to take the fans from two CPUs, mount them onto something, and get that something to float off the ground

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

Attempt to mount fans on cardboard or plastic plate

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

I used just one motor, which was different than planned. The I mounted it onto a paper plate, but forgot to cut a hole to allow a flow of air. My goal for this weekend was not reached, but I have learned a lot. I am looking forward to learning even more net week.

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

My Fourth task
My Fourth Task is to take the arduino, hook it up to a motor shield, and power them both with the batteries from the hovercraft

Summary of actual work over fourth weekend
I did what I had planned to do. In addition, I took a spare motor and tested it to see whether or not the way I had hooked everything up worked. Fortunately, the motor ran well.

Week4 Narrative
When my group got back together, I hooked up the arduino/motor shield to one of the motors on the hovercraft, and powered it on. At first it wouldn't work because of some wiring issues, but with some help from my team, it worked. During the next four weeks, my job will be to get it to work consistently, and to get it to respond to a remote control. Once that is done, I will need to get it to respond on its own to an infrared sensor.

Hovercraft team page

Write problem/project Goal
To create a hovercraft.

My First Task
Create various possible prototypes using design software.

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

I planned to make multiple prototypes of hovercraft without much problem. However, I spent most of the weekend instead learning to use 123d so that I could have a full understanding of the software package.

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

Over the weekend I used 123d to design a prototype of a hovercraft to fulfill our needs in the project. I looked a various other hovercrafts to gain some understanding of the design and added many of my own elements. I created components of the craft to assist with being able to operate autonomously as well as weight distribution, steering, and air manipulation. After combing over sketches and blueprints of various components by engineers and enthusiasts alike I created my idea of the ideal hovercraft for my team.

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

Over the second weekend it will be my responisibility to edit and manage the team page and its information.

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

There wasn't as much work involved in my responsibilities as I thought so I had to push forward in the project to stay busy.

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

Analyzed and learned Lego NXT software used with the brick device. Equipped the NXT light sensor to the brick and ran the software package. Learned how the software package analyzes and distributes data. Found the pin layout for the light sensor and which wires correspond to which function.

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

My Job over this weekend will be to figure out how to wire the NXT light sensor to the hovercraft so that a brick does not need to be incorporated in the design.

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

I did exactly what I had planned to do over the weekend. However, there was issues which made me take different approaches. For example, there was issues with the software which made it difficult to get the light sensor running.

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

cut and stripped the wires from the NXT light sensor so that they can be wired to the arduino instead of the brick.

soldered on solid wires to the NXT copper wire to promote connectivity.

Researched Wire layouts for NXT light sensor with the arduino board and tested all of them.

Tried to find the software that works with the NXT light sensor so that data can be read from it.

Write problem/project Goal
Catalog old high voltage science demonstrations and update/repair/create them.

My First Task
Take home Various Science demos, catalog and learn more about them.

Summary of actual work over first weekend
I took all of the materials in the bin and fiqured out their function.

Week1 Narrative
Over the weekend various equipment was taken out of respective plastic bags, assembled, manuals read, function researched, and cleaned.

There were:
 * -Two charge spheres: These metal spheres are insulated from their bases and are intended to hold a charge. They could be used as a part of a Van de Graaff generator
 * -One Power Supply: This 100 watt supply provides power from 2-12 volts in 2 voltage intervals
 * -A cassette tape eraser: Uses a coil to produce a magnetic field and erase the magnetic strip on a cassette tape.
 * -"Dr Ficher Bulbs": A stoutly constructed light bulb
 * -Electrometer: Unopened since 1987, this electroscope has extremely low impedance (pico-amperes) but will be damaged if it is used to measure voltages higher than 100. It is intended to measure static electric voltage potential.
 * -Flat Disk and Tapered Cylinder: These are a part of a science kit intended to measure voltage potentials between differently shaped surfaces. Could be used as a conductor surface.
 * -High Voltage Probe: To be used in conjunction with a multimeter or voltmeter to measure high voltages normally outside the meter's range.

In addition various manuals were put into a three ring binder.

My Second Task
Update Wikiversity with project information and possible add tutorials on how to use certain devices, such as the handheld Tesla coil. Also work on creating a Thomson Elihu Coil (ring-flinger)from the coil in the cassette tape eraser.

Summary of actual work over second weekend
Some Wikiversity pages were updated. I created a miniature Elihu Thomson Coil. In my journal, the outlines for tutorials for using the handheld Tesla coil and probe were written.

Week2 Narrative
A miniature Elihu Thomson coil was created, It uses wall socket power in a small electromagnetic coil and and extended magnetic field to induce current in a circular conductor around the ferric core. The current produces its own magnetic field, causing the "ring" of electrically conductive material to float, and, if the field is strong enough and the material light enough, flung off the end of the core. I also experimented with the Handheld Tesla coil and wrote down a tutorial (in my journal) on its proper usage. A tutorial was also worked on for the usage of the high voltage probe.

My Third task
Create the Tutorials on wikiversity

Summary of actual work over third weekend
I've created some wikiversity pages for tutorials of various devices, however, no actual work was done. What I need to do if figure out what I can be doing for the project, since cataloging the various devices function is not what the project is about.

Week3 Narrative
The tutorials
 * Tesla Coil
 * High Voltage Probe

Picture of the Coil I worked on. The wires visible need to be made safe, they have 115-120v ac running through them, and have no switch

My Fourth task

 * Diagnose Tesla coil Problems with inconsistent spark production.
 * Make Model of Elihu Thomson coil safe for usage.

Summary of actual work over fourth weekend

 * The Tesla coil was taken farther apart, and its functions looked over. Parts were cleaned to improve function and reliability.
 * The Elihu Thompson coil model was made safe for usage, no more exposed wires. Also an attempt at creating an aluminum ring for the "ring flinger" failed, and I learned that you cannot solder aluminium.

Week4 Narrative

 * [[File:CoilSwitch1.jpg]]

The switch to be attached

 * [[File:CoilSwitch2.jpg]]

The switch with contacts insulated

 * [[File:TestingCoilSwitch1.jpg]]

The Switch being tested to determine the open and closed positions. This is closed.

 * [[File:TestingCoilSwitch2.jpg]]

The switch open

 * [[File:CoilBefore.jpg]]

The coil with the leads tinned and ready for the switch to be soldered on. Before the bare leads had 115-120v AC going through them, not ideal to have un-insulated.

 * [[File:CoilAfter.jpg]]

The coil with the leads attached, notice there is still bare wires that are unsafe.

 * [[File:CoilInsulated.jpg]]

Finished coil model, with attached switch and no bare wires or leads.

 * [[File:AluminumRing.jpg]]

The failed attempt to create an Aluminum ring for the "ring flinger" (Elihu Thomson Coil). The ring was made by folding a piece of aluminum foil into a strip, then rapt around a metal dowel rod to created the ring shape. Then it was attempted to be soldered together, but solder does not work well with aluminum.

 * [[File:TeslaCoilInside.jpg]]

The Casing removed from the coil, ready to be observed and further taken apart for diagnosis of parts and finding the cause for inconsistent operation.

 * [[File:SparkGap.jpg]]

A picture of the coil in operation, specifically the area inside where a small spark (arching) takes place, to generate the larger sparks at the tip.

 * [[File:SparkAreaDisassembled.jpg]]

The spark gap assembly taken apart to clean contacts. The file used can be seen in the photo.

Write problem/project Goal
Design and make the Escher Impossible Ball Illusion

My First Task
My first task is to research the Escher models and find out what they are and which one I should make.

Summary of actual work over first weekend
I not only did some research, but also started planning a course of action and design

Week1 Narrative
I researched Escher the person and also his work. I got some pictures and video. And finally I decided what design to use to build the ramps.

My Second Task
Build the Escher Illusion with the supplies given to me last week

Summary of actual work over second weekend
The only difference was that I had originally planned to make the model and the viewing apparatus, but I ran out of time, so I just made the Model.

Week2 Narrative
This week, I built the Escher Gravity Illusion Model (Different Angle). It took me only four hours, however I was not able to complete the viewing box.

My Third task
Over the third weekend, I am planning on constructing a viewing apparatus, which will only allow the Escher model to be seen at the exact angle that creates the illusion. Also I am planning on uploading some pictures of the building process of both the model and the viewing apparatus.

Summary of actual work over third weekend
What I did over the past week is exactly what I said I would do.

Week3 Narrative
Over this past week, I built a box that allows people to view the Escher at the angle which creates the illusion (by looking through a window I cut out of the box). I also glued a frame onto the base of the box so that the model won't move, but it can be removed to observe. Finally I took and uploaded pictures of some of the individual pieces and the finished project.

My Fourth task
For the final week of the project, I am going to try to build the Escher waterfall illusion

Summary of actual work over fourth weekend
Well I was going to make the waterfall illusion, but then found out I have over 2000 points so decided to finish the team page instead.

Week4 Narrative
I completed the Escher Team Page

Write problem/project Goal
Developing power supply apparatus solutions for other projects.

Converting a computer power supply to a lab power supply.

My First Task
I am going to try to connect a power supply to a digital circuit in order to make it work. All power supplies produce maximum 12 volt, but I need 24 volt for my circuit. Therefore, I should connect two power supplies in a serial form to produce the proper voltage.I need some Resistance to have a proper current.( I need to produce 1.2 Amp for the specific circuit.)

Summary of actual work over first weekend
I find out the new purpose of the project which was converting a computer power supply to a lab one.

I made holes, attached binding posts to the them. connect all same-color wires together; one black to green wire. I measured the voltage of each bunch of wires.

Week1 Narrative
First, in class, I made 4 holes in one side of the power supply and attached 4 binding posts to them.

I took the power supply, power cable, a 10 Ohm Resistor, and a multimeter home. I connected the resistor to a black wire and a red wire. I connected another black wire to the only green wire. then, I gathered and connected all remaining black wires together. I did same for red wires, but I connected the only purple wire to them as well. I did same for orange wires; also, I connected them to the only brown wire. moreover, I connected all yellow and white wires together. in addition, I kept a black wire for connecting to a LED with the gray wire. Finally, I measured the voltage of each bunch of wires by multimeter. here is the results:

Black: Ground. Red: 5 volt. Orange: 3.3 volt. Yellow and White: 12 volt. And Blue: -12 volt.

According to results, the power supply should have 5 binding posts which already has 4.

I also uploaded a video which shows my work. Here is the link of my youtube video:

[| Power Supply Video 1]

My Second Task
I've got to attach another binding post. Also, because there are many wires and it is difficult to gather them in a small place, I want to make 5 new holes on the opposite side of the power supply and attach binding posts to them; therefore, I'll have more space for wires. In addition, I will make a tiny hole for LED. Finally, I will connect wires to binding post and the power supply will be ready.

Summary of actual work over second weekend
On Thursday, I made holes bigger and connected 5 brand-new binding posts to them. since, the power supply was almost done, I took another power supply home for converting it to a Lab power supply. I took apart it and did same as the previous one. I connected two 20 ohm power resistors in parallel form to get 10 ohm ,then I connected a red and a black wire to them. After that, i connected a black wire to the green wire to turn the power supply on. Next, I gathered and connected all remaining same color wires together. Finally, I determined the locations of binding posts and LED on one side of the power supply by pen.

Week2 Narrative
I took apart the power supply. I connected two 20 ohm power resistors in parallelform to get 10 ohm because I couldn't find a 10 ohm power resistor. I cut sockets and all wires to make them shorter. I connected a red wire and a black wire to the resistors and stuck them inside the case of the power supply. I connected the green wire to another black wire to turn the power supply on. I gathered all same-color wires together, made them shorter, connected them together, and finally connected a same-color piece of wire to each bunch of wires to make them long enough to reach the binding posts and to make my work more organized. After that, I wrapped the bunch of black wires, red wires, yellow wires, and orange wires together and placed them in the space I got in the power supply. At the end I had, a blue wire, a brown wire, and pink wire. I knew the blue wire is -12 volt, but I was not sure about the rest;therefore, I checked them by multimeter, I used each with ground, but I got 3.3 volt for brown and 5 for pink, so I connected the pink to the reds, but the power supply turned off and didn't turned on for about 15 minutes, so I realized I did something wrong. I guessed that the pink could be -5 volt and brown -3.3 as well. I turned on the power supply on and I connected the multimeter to pink and the reds. It showed 0, so I found out that my guess was correct. I did same for brown and orange and got same result. Finally, I determined the locations of binding posts and LED by pen. I need 7 binding posts: Black as ground, yellow as 12 volt, red as 5, orange as 3.3, blue as -12, pink as -5, brown as -3.3.

After measuring the pink and the brown by multimeter and comparing with the red and the orange, I realized they are same, so i need 5 binding posts.

I have added new pictures.

Also, I've uploaded a video on YouTube. Here is the link of the video which shows my work:

Converting the second power supply

My Third task
I am going to drill 5 holes and attach binding posts to them, make a tiny hole for LED, connect the gray wire to its cathode and connect a black wire to 330 ohm resistor while the resistor is connected to the LED's anode.

Summary of actual work over third weekend
In class, I connected a 360 ohm resistor to a LED and a black wire. I connected the gray wire to the cathode of the LED. I drilled a tiny hole and put the LED in it. I also drilled 5 more holes and attached the binding posts to them. Then, I connected each wire to each binding posts and checked their voltage by multimeter. Finally, I closed the power supply and stuck a label under binding posts and wrote their voltage on it.

Over the weekend, I took the 3rd power supply home. I did exactly same process. Connecting all same color wires, connecting a balck and a red wire to two 25 ohm power resistors, connecting the green wire to a black wire, connecting a 360 ohm resistor to a black wire and a LED, and connecting the gray wire to the LED.

Week3 Narrative
In class, I connected a 360 ohm resistor to a black wire, then connected its other leg to anode of the LED. Next I connected the gray wire to cathode of the LED. For determining the anode and cathode of the LED, I used the diode feature of the multimeter. I put the mutimeter on diode and connected it to the LED. The LED turned on, so I figured out which leg is cathode and which is anode. After that, I wrapped them by electrical tape. Then, I drilled a tiny hole for LED and placed it in it. Next, I drilled 5 holes and attached 5 binding posts to them. Then, I connected each wire to to each binding post and screwed them. After that, I put a label under binding posts and wrote their voltage. Finally, I checked their voltage by multimeter for making sure that they work properly and closed the power supply and screwed it. I do not know the reason, but the LED blinking when the power supply is on, instead of being solid on. I guess it is related to the brand and model of power supplies.

I've added some pictures.

My Fourth task
I am going to drill 5 holes and attach 5 binding posts to them and connecting wires to binding posts. also, I will Drill a hole for the LED, label binding posts, and done!

Summary of actual work over fourth weekend
In Class, I drilled 5 holes and attached binding posts to them. I also drilled a smaller hole for the LED. I connected each wire- black, red, orange, yellow, and blue- to a binding post and soldered it. Then, I placed the LED in its hole and closed the power supply. Then, I labeled the binding posts. Finally, I checked the power supply.

Week4 Narrative
I held the power supply by vise and used 3 different size drills. I also put the drill, which I used, into a glass of water from time to time to cool it down. It really worked and I easily and neatly drilled holes. Then I attached binding posts to the holes tightly. Next, I connected each wires- black, red, orange, yellow, and blue- to each binding posts and soldered them. After that, I put the LED into its hole, closed the power supply, and labeled the binding posts. Finally, I checked the power supply by multimeters.

Summary of actual work over fourth weekend
This week my project changed directions again. With the other groups getting the ESC controller working with the power boxes built, I moved on to completing the RC Controller/Toy Hack, and applying what I had learned to the hovercraft.

Week4 Narrative
My first task was to complete the Arduino Tutorial, [|RC Toy Hack]. I worked my way through the tutorial to gain a solid understanding of how the Arduino/RC Controller/control board all interact. I also needed to study some of the Arduino programming language in order to figure out what the example in the tutorial was doing. After completing the tutorial, I was able to successfully read data via the Arduino serial monitor, for the action of one of the switches on the RC Controller. With this understanding of the rc controller, I was then able to start expanding on what I had learned by adding the code necessary to read data from both controls simultaneously. This was mostly a matter of copying certain lines of code and creating a few new variables to identify the second input and output. After much trial and error, I was able to create the proper coding to allow the rc controller to communicate with both motor outputs at the same time.

My next move was to apply this understanding of the RC Toy Hack tutorial to my group's hovercraft. The first thing I had to do was take disassemble the hovercraft in order to get at the control board. With the hovercraft body taken apart, access was now granted to the internal components. The first thing I had to do was separate the hovercraft into two pieces so that Wendell and I would be able to work on separate parts of the project at the same time. The hovercraft's battery pack was separated from the rest of the body and given to Wendell. He will use that power source to try to power both the Hovercraft and the Arduino controller. With my half of the hovercraft, I was responsible for wiring the hovercraft fans and power into the Arduino and establish communication between the motors, control board, Arduino, and rc controller.

After running through some initial testing I have found that the Arduino is capable of supplying

3D Scan Team Page

Project Goal

 * Use the Kinect to capture a 3D image and print it using the Maker Bot

My First Task

 * Reading all of the project's history which was started last semester, Fall 2011, by 501_cupcakes, and moving the most prevalent

information to the 3D Scan page on wikiversity so that it is more accessible will be my first task. I will research 3D scanning and explore

the subsystems to the project.

Summary of actual work over first weekend
How is what you did different than what you planned?
 * First of all, I spontaneously created a team collaboration page in Google Docs that is accessible to my team members through Canvas,

the school's course management system. Then, I noted the accomplishments of the past teams that have worked on the 3D scan project.

Next, I started preparing a presentation about the issue of not having an easily accessible 3D scanning device here at Howard Community

College. Finally, I looked for inspiration on 3D scanning and tips on giving a good presentation.

Week1 Narrative

 * Last Thursday, I promised my team that I would review the project history and research to obtain a better understanding of the

challenges we face in completing the project. Before leaving, I started a Google Doc collaboration through Canvas, Howard Community

College's (HCC) course management system, so that my team could keep in touch quickly and easily. In the document I defined the project's

requirements in using particular subsystems. I wanted to make sure that the focus was on getting the Kinect to work with the Maker Bot

because the last team working on 3D scanning was unable to create a quick and easy way to scan, model, and print 3D objects. Similarly, I

wanted the processing stages to use a software that will be easy to use and extremely helpful to future students and engineers at HCC.
 * Upon starting my research, I found a full tutorial on how to turn the Kinect into a 3D scanner. After a while of researching, I had found

several images of objects that had been scanned and printed in 3D, instructional methods of working with model files, some of the recent

history on 3D scanning (there is not a lot, so HCC students should start writing it), and a couple fun/inspirational links to websites like

The Top Ten Best Kinect Hacks and 3D Printing Is The Cover Story Of USA Today. I shared all of this in the collaboration document to

give my team a better understanding of the project and inspire and motivate them to push the project forward.

My Second Task

 * This weekend I plan on using the tutorial here on Wikiversity to set up the MakerBot and print a 3D object file which I will download from

an internet archive. If I come across any obstacles in doing so, I plan on documenting them in my notebook, so that I can improve the tutorial.

Also, I sent a message to the software developer engineers at INUS Technology, Inc. the creators of RapidForm XOR about receiving a

demo copy of their state of the art unreleased 3D software and having a presentation from one of their engineers for HCC's engineering club,

and I have already received a personal e-mail from them that told me to expect a call from one of their engineers tomorrow. I plan on doing my

best to put these plans into action.

Summary of actual work over second weekend
How is what you did different than what you planned?
 * I left a message for the Rapidform developers, but haven't heard back. Over the weekend I re-installed the drivers for the MakerBot, and was

able to print out a cone shaped model with a few additional instructions from a student worker.

Week2 Narrative

 * In order to force the MakerBot to print at a lower temperature, I needed to change a line of code in the generated g-code. Notably, the new

necessary temperature setting is 180 degrees Celsius. I hypothesize that the reason for this is an error in the MakerBots calibration, since

new parts have been installed on it. And, the actual temperature of the machine and the one specified originally in the code is 220 degrees

Celsius. I learned that the MakerBot prints a reflection of the model that is seen in the ReplicatorG software by printing a key chain that has

the words; "Start Making." Thus, to print something and spell it from left to right, the words must be backwards in the software (reflected

across the x-axis.) I drew up some sketches of the subsystems that might attract attention if they were made into 3D visual props and/or

added to the project poster as drawings or pictures. At the end of the week, I installed AutoDesk Maya, watched the basic tutorials, and

became familiar with the controls and most of the interface buttons.

My Third task

 * For my third task I plan on learning how to clean up a point cloud in MeshLab, save it as an object file, and render it in Maya in

preparation for it to be printed. Also, I will organize materials for a project poster/backboard/exhibit.

Summary of actual work over third weekend

 * I did not make it to Office Depot or Kinko's to pick up presentation tools. I also was not able to work on a point cloud because I did not

have the tools to make one. Instead, I spent some time learning to use the MakerBot.

Week3 Narrative

 * I was unable to print with the MakerBot upon arriving, but I was able to troubleshoot the problem and found that the easiest solution

fixed the problem. Filament was not being extruded. Though, there are many reasons this might happen, the solution involved tightening

the thumbscrew pressing the material wire into the CNC motor. I outlined this and the steps I took when I had to re-install the drivers in

the MakerBot tutorials.

My Fourth task

 * Make almost done.jpg plan on taking pictures while pushing the project forward. This way I will have material to create a presentation without taking too

much time away from successfully getting a scanned object printed. I will work with the Kinect and processing software to get a point

cloud ready for Meshlab. Afterwards, I will edit and convert the file until it can be printed using the MakerBot.

Summary of actual work over fourth weekend
How is what you did different than what you planned?
 * Worked through every step of the project alone, including designing a turnatable.

Week4 Narrative

 * Throughout the week I was sidetracked with the MakerBot tutorials, my LCD side project, and organizing presentation materials for

the project. However, I came to school Friday afternoon and made a great deal of progress. Dr. Foerster rolled back one of the computers

to a Windows 7 32 bit operating system, so that I could push the project forward. Both software packages that I have found to create a

three hundred sixty degree three dimensional view are designed to run on the Mac OS or Win 7 32 bit OS. I began by downloading the

software packages. From this point on, I took screenshots of every step I took in preparation to build a tutorial here on Wikiversity. I

tested each of the execution files in the RGB demo. I started to realize that I was going to need some additional instruction to callibrate

the Kinect so that it would build a 360 degree mesh of the appropriate object. However, I found that I could still create a 360 degree view

of a symmetrical object such as a soda can as long as I centered it in the Kinect's focal point. I created a temporary turntable made out of

a cardboard box and a circular platform that had a rotating ball-bearing bracket attached to it's bottom side. Also, I put tape inside the

box, but that turned out to be an unnecessary step because the tape method or use of a checkerboard pattern on a paper is used when

calibrating the Kinect, which I did not do. When I scanned the soda with my new turntable I had placed the Kinect almost directly above the

composition, so my point cloud consisted of data points for solely the top of the can. Next, I quickly captured a point cloud of myself from

a frontal view. Then, I opened the mesh of myself which is saved as a polygon file (.ply) in MeshLab. I deleted the point cloud of the room

in the background and performed some sampling and reconstruction filtering to connect the dots and turn the mesh into an object that can be

saved into the file type used by the MakerBot for printing. However, some objects may require a few additional editing techniques before they

can be printed. For example the model of me was just a contour and did not have a base. After watching several more youtube videos, I have

come to the conclusion that the better software for creating a 360 degree view of an object is ReconstructMe. I plan on making a tutorial

related to the subject matter seen in this example video in addition to the 3D Scanning with RGBDemo tutorial (will create link here asap).

Bring everything i've worked on so far and create a 3d scan of an object using xbox kinect.

In week one I decided to work with Microsoft sdk for the kinect, however the sdk did not allow for the saving of the depth scan in any file format. Therefore I decided to work with another sdk based on the libfreenect-software from http://openkinect.org. I scanned an object using Dlibs demo software from https://github.com/diwi/dLibs and the Xbox 360 kinect and then saved that file in an obj format. I was able to complete my task, I successfully scanned a 3D model of myself,saved it as an obj file and rendered it in Maya.

Week2 Narrative
I downloaded the drivers required to make the kinect work with the computer from https://github.com/diwi/dLibs. I downloaded the zip file which contained the examples, library, reference and src folders, however for this project I only needed the examples folder and the library folder. The examples folder holds all the demo software which allows the kinect to scan and save a 3D model. The library folder holds the Drivers for the kinect, it has three drivers and they are individually installed in the device manger. Furthermore, in order to run the demo software the processing environment needs to be installed http://processing.org/, it is an open source programming language and editor which is really good at creating interactions. Finally I was able to scan and save a 3d image of myself by running the example program kinect_basic_3D_export_scan in processing. I also used mesh lab to tweak, rotate and export the 3d model as an alias wave front object extension, which would allow me to open the mesh in any 3d package.

My Third task
Up until now I was able to scan an object only from a single point of view and it was only a single snap shot, for my third task I will begin working with other demo software’s that would allow me to scan an object from multiple points without have to scan multiple times. This will create a 3d model which I would be able to rotate in all directions 3d modeling package like Maya or 123d.

Summary of actual work over third weekend
In week two I decided that I would look for demo software for the kinect that would allow me to scan an object in 360 degree and save that model as an obj format. I was able to find this software as well as the drivers required to make the kinect work with the software. http://labs.manctl.com/rgbdemo/index.php/Main/Download

Week3 Narrative
To make the kinect work with the software I installed three drives, however there is another all-in-one installer provide by Zigfu that take cares of the entire process of installing drivers. I download and installed the Zigfu installer http://zigfu.com/browserplugin.html or http://labs.manctl.com/rgbdemo/index.php/Main/Download. After installing the drivers I downloaded the RGBDemo-7.0 from http://labs.manctl.com/rgbdemo/index.php/Documentation/Demos. This software demo contains exe files that take depth data from kinect and show it as point cloud data, there are also other demos that can render in other 3d formats, ie triangles. The one I was interested in most was the Demo of object model acquisition with markers, this demo software allows for the scanning and saving of an object in full 3d, the model can then be rotated in full 360 degrees in any 3d package and even printed using a 3d printer. However I encounter a minor problem, the demo software is available only for 32bit operating systems and does not work well with the 64bit systems. I was able to run some of the components, such as the point cloud and save it but I was not able to run the object model acquisition demo. Therefore I was not able to create a 360 degree view of an object. There are a few other things that are needed for the object model acquisition demo to work properly in addition to the 32bit operating system. First the kinect needs to be collaborated using one of the demos provide in the rgbd demo with a marker board Some of the details can be found here http://nicolas.burrus.name/index.php/Research/KinectCalibration and here http://labs.manctl.com/rgbdemo/index.php/Documentation/Calibration. After running the collaborating demo software, the kinect collaborates with the checkered marker board should able to scan a 360 degree model.

My Fourth task
For my fourth task I want to run the demo software on a 32bit operating system and try to scan an object in 3D and hopefully get the same result as in this video.http://www.youtube.com/watch?v=iK_r2Ru3wP4

Summary of actual work over fourth weekend
At the end of week three I decided that I would make use of a 32 bit computer to run the rgbDemo software, however I was unable to find one and was not able to scan an object in full 360 degree view. I decided to take a different approach that involved cloud point data from kinect to create a model that looks 3D. The process for creating a cloud point requires installing some software and libraries,I have covered the steps in the following tutorial.

 * Tutorial on scanning object using kinect

Week4 Narrative
The first step was to create a cloud point of an object, in this case i decided to make a cloud point of my face. This was done using kinect and processing. I then brought the mesh in mesh lab for cleaning up. The actual cleaning up of the mesh requires several steps which I have covered in this tutorial. I was able to create a clean version of the cloud point mesh which can be brought into the maker bot software for preparing it to be printed.

Complete Project Page
I was able to get the kinect to work on the computer using drivers, I was also able to make use of some of the features of kinect such as the depth data and cloud point data. I was able to scan and save cloud point data which I cleaned up using mesh lab and created a file ready for 3D printing. However I was not able to scan an object in full 360 degree view due to the fact that I was not able to find a computer with 32bit operating system installed on it, but the process of creating a full 3d scan is covered in my 360 degree scan tutorial.Scanning an object using kinect: Full 360degree view

Write problem/project Goal
Design and Create a StrandBeest

My First Task
To bring to the global page the highlights of the work done by the previous group.

Aditional tasking was to research the working of the mechanism that create movement within the Beests and to create a base knowledge to draw from. This was a general tasking to be done by each member seperately.

Summary of actual work over first weekend
Updated the global page with the cream of the crop from the previous groups work. Also researched and created a leg assembly from Jansen's design.

Week1 Narrative
I have edited the previous groups work where apropriate due to preceived negativity within the group, added content that may or maynot be new since the time the previous group worked on the project. Updates to their work include adding 2 additional links and additional written content. The spirit and intention of the previous group has been maintained to the best of my ability. 18 edits of the global page to include 5 minor edits. To meet the spirit of the additional tasking I build 1 leg assembly from Jansen's original design HERE.

My Second Task
My tasking for the second weekend is to design the drive assembly. Another member of the group is also going to work this same assignment seperately. Tuesday we will compare and take the best ideas from the two designs and merge where aplicable. A third member of the group will design the hinges and the forth will measure out and cut of required pieces.

Summary of actual work over second weekend
I designed and built a model of the drive assembly.

Week2 Narrative
While the exact dimentions of the strandbeest hasn't been hammered out yet, I designed a drive assembly from an approximation. The first problem I had to deal with was the materials and tools. This was only intended to be a model so after failing a second time trying to bend a thick wire I had bought for the crankshaft the first weekend I decided to go for ease of use and work with plastic. This actually lead me to the same straight angle design that my group-mate thought of as well... Great minds. 1 groupmember did not attend class on tuesday so his progress is unknown.

My Third task
My task for the third weekend so far is to research the cost of having a crankshaft professionally welded. Additional tasking for each member is to start migrating cream of the crop of each "mywork" section to the group page.

Summary of actual work over third weekend
one of the things I decided to do differantly is create a -->> /tutorial/ <<-- to progress the group page. Additionally I sanded and filed all of the wooden pieces to prevent the rubbing problems we were having with the models we've built.

Week3 Narrative
The first thing I focused on was moving some of my work to the group page, I had starting moving some things from my teammates pages but thought that they should be the ones to choose which they wanted or at least for everyone to agree on it. Next I spent another day at home depot trying to get ideas for materials and construction of the crank shaft. I am becoming very familiar with the layout of that store since i have been in there for at least 5 hours in the past 3 weeks working on this and another of my own projects. One day I was able to get out of work to spend a day in the school filing and sanding all of the pieces of the leg assemblies to avoid the rubbing that we were experiencing with the model Brian had made. This made a considerable mess and took far longer than I had expected when I undertook this task. After I completed this i got around to testing out some of the ideas I had for the shaft. Ideas: copper piping with small welds was rejected because the welds would have to be done around the wooden assmblies with very little room, PVC elbow joints was rejected due to the fact that they would require a large gap between the part of the leg assembly attached to the "spindle" part of the crankshaft and the part that attached to the "raised" part of the crank. The pieces of wood that were designed to be flat against each other would be forced to have a 40* angle and this would cause scrapping and rubbing from each leg rendering it imobile. Wood glue was rejected based on my testing but this needs revisiting, the instructor says the woodglue is sound but requires a flat piece and small amount. Unfortunately there may not be time enough for continued testing.

The nail in the ends of dowel was the best bet in my testing. While ineligant it seems to have held fairly well. The dowel would have to be of sufficiant diameter to allow multiple nails. This is however extremely difficult to construct around the legs and would only allow for minimal preconstruction. Several hinges were also designed and tested. I was able to find already in the possesion of the engineering supplies plastic tabs that fit nicely and with the application of a little super glue seem to be able to withstand the forces of the moving assembly.

My Fourth task
Each member was tasked with the construction of two leg assemblies. I was also Tasked with continued work on the crank shaft.

Summary of actual work over fourth weekend
I came in to school and constructed two leg assemblies. Additionally I continued work on the crank shaft.

Week4 Narrative
The bulk of the remaining work was assembling the legs of the beest. I came into school and put together the two that i was assigned to do. I noticed the others hadnt yet come so i was going to put one or two more together but couldnt find the rest of the pieces required. As it turns out what i was looking for was just moved across the room. Some additional trimming of pieces will still be needed due to a problem with the number of each of the pieces, but nothing that cannot be worked around. Altimately the leg assemblies that we had agreed to put together over the weekend hadnt been assembled, save for the two i put together and the one we collectively assembled last week.

The crankshaft has continued to present difficulties for me as listed in previous narratives. However, in discusion with the group we rehashed an idea I had dismissed early and found that it may end up being our best bet. A thick, ridged wire reinforced by securing it to the wooden part of the crank from the design. Testing would need to be done and an order of parts. The best way the collective mind of the group could think of to secure it was heavy duty staples in a back and forth (zipper) design to keep the wire from moving back and forth. required part: Lincoln Electric 3/32 in. Fleetweld 180 Stick Electrode Model # ED031152

Additionally I created a 3D model of the crankshaft to provide a better understanding of what I was going for using 123D. Each member was also separately to create the project poster and e-mail it and total hours worked to each other for final group page.
