1.0 Introductory Material

This section will give the basic background information needed to understand the senior design lab project. The introductory material is broken into the following sections:

Executive summary Acknowledgement Problem statement Operating environment Intended users Intended uses Assumptions and limitations Expected end product and other deliverables

Figure 1 – Current Senior Design Lab in Use

1.1 Executive Summary

This section will summarize the senior design lab project and is broken down into the following sections.

Need for this project Project activities Project results Future work

1.1.1 Need for the project

Architectural plans are currently being developed to renovate and expand Coover Hall. When these plans are completed and funding is available, the senior design facilities will

6

be moved from their current location back into Coover Hall. The objective of this project is to produce a document that will facilitate the transition to the new lab. In addition we will produce a multimedia presentation facility that will allow students to easily control and allow for recording of their presentations.

1.1.2 Project Activities

The team conducted a survey of senior design students and took inventory in order to assess the needs of the new lab facilities. A layout was created to reflect this information, and a 3-D walkthrough was used to help test the layout.

An addition to scope of the project was added in April of 2005 when the client requested the creation of a multimedia presentation facility (MPF) for the new lab. The MPF should allow senior design students to easily control all aspects of their industrial review presentations, and allow for recording of the presentation.

1.1.3 Project Results

This document, the end product report, has been created and specifies the requirements of moving senior design to Coover Hall, and details how the facilities should be laid out. A 3-D walkthrough and layouts have also been created and will aid in this transition.

1.1.4 Future work

Recommendations for future work would include the following. The addition of an embedded systems station would facilitate the creation of embedded systems that are required in many senior design projects. This dedicated computer workstation would have all the tools needed to create an embedded system.

Also, a website for tool checkout and room reservations would allow students to check out tools or rooms to be used for their senior design projects. This would help students to easily see what is available, and allow the senior design coordinators to easily track tools and help prevent tools from being stolen.

1.2 Acknowledgement

The members of this team would like to thank Dr. Lamont and Prof. Patterson for their contribution of advice, and technical expertise. The team would also like to thank Dr. Jacobson, Chair of the ECpE Building Committee, for allowing the team to be involved with the senior design portion of the new Coover Hall. The team would also like to thank Dr. Rover and Dr. Kushner for their help with the possible addition of a multidisciplinary senior design component to the new facility. Finally we would like to thank Matt Darbyshire from ITC and Tim Wright from Pratt Audio Video for their technical expertise.

1.3 Problem Statement

Upon completion of the expansion and renovation of Coover Hall, senior design will have to vacate their current space on the third floor of the Town Engineering Building. When these plans are put into motion, it will be possible to establish a senior design lab in Coover Hall. A senior design lab will require the necessary tools, instruments, and space to be utilized by senior design project groups. Pictures of the current senior design facility can be seen in Appendix A.

The goal of this project was to provide a document to assist in the transition from the current lab in the Town Engineering Building to the new senior design lab. The document includes sections detailing all the needs of senior design, and how these needs can best be fulfilled with the resources provided by the new facilities.

1.4 Operating Environment

The operating environment for the new senior design facility will be a high tech laboratory for senior design students and will include the following types of facilities and capabilities.

Circuit fabrication Software development Meeting and presentation facilities Limited mechanical facilities

1.5 Intended Users

The intended users of this document are the senior design coordinators and any other individuals involved in moving senior design to its new location in Coover Hall.

1.6 Intended Uses

This document should be used to in moving the facilities of senior design from Town Hall to Coover Hall. The document includes detailed descriptions of each room, and what the final contents of these rooms should be. Using this document during the transition will help ensure the new senior design facilities are as useful as possible to the students.

2.1.3 Approaches considered and used

This section explains the approaches to the project that were considered and eventually used and will be broken into the following sections:



For the end product report detailing the design of the new senior design lab, a number of approaches were considered.

The first approached considered was designing an ideal senior design lab. This had the advantage of allowing work to be done on the project with having the required information from the architects and the building committee; however, an end product document of this nature would be less useful to the client.

The second approach considered was designing the actual senior design lab. This option was desirable because the final product would be more usable for the client; however, it also required information that was not available at the time, such as the final layout of Coover Hall.

In the beginning of the project, the first, ideal lab, approach was taken. This allowed the team to determine what would be needed and what could be added to the actual senior design lab. When the information that was needed became available in August of 2005, the team transitioned to designing the actual senior design lab. This allowed the team to add some improvements into the actual lab design, while still producing a useful document for the client. To complete this process, the second semester students of senior design were surveyed to try to determine what was needed that was not available. An inventory was taken of the current senior design labs and facilities, everything was laid out, and a 3-D walkthrough was created to help see how the end product would look.


12

The audio video system is complex. The first approach considered was running all the video inputs to the projector. This would have made switching the video much easier because it would have been done at the projector. The advantage was that we wouldn’t have needed the expensive switcher/scalar unit. However, the disadvantages affect the client’s requirements that it be easy to use and mobile. A bunch of bulky cables to hook up and store did not allow the system to be very mobile or easy to use.

The second approach considered was switching all the audio and video internally. The advantages are that just one cable is running out to the projector making the cables easy to store and hookup per the client’s wishes. The disadvantage was that the switcher/scalar unit added a significant cost to the project, and a serial controller had to be manually programmed to control it.

The team decided to use the second approach because that approach fulfilled the client’s requirements, and the budget allowed for the extra expense.

2.1.4 Implementation process

This section explains the implementation process for the project and will be broken into the following sections:



Implementation of the end product report required a number of different activities.

First, a complete inventory of the senior design labs was taken. This allowed the team to know what was available to work with, and the facilities for which room would be needed. Later the inventory was used to assign equipment and tools to specific rooms in the new design. From this design a 3-D walkthrough was created.

Also a survey was taken from the second semester senior design students. This survey covered topics such as test equipment, storage space, available software and computer equipment, and was used to help design the new lab.


Implementation of the MPF required a number of different activities.

First, all the audio and video equipment was connected together and tested before the equipment was installed in the MPF enclosure. Then all the equipment was fit into the lectern enclosure and tested once more for functionality.

13

The only problem encountered with the first step was that a capacitor exploded on the LCD screen. The capacitor was replaced and the LCD functioned properly once again. Another problem encountered was that the enclosure wasn’t designed for the LCD display to be tilted back at an angle to reduce glare and make it easier to see. This problem was handled by adding spacers to the top mounting holes of the display. This did not provide as much tilt to the LCD display as desired, but was a large improvement from the original, vertical position. If anything was done differently on this project, the LCD would have been mounted at a greater angle. This would also have allowed the final height of the lectern enclosure to be reduced.

2.1.5 End product testing

Because of the nature of building design, testing of the design will not be possible; however, a layout and a 3-D walkthrough of the design were created to help envision how the final design will actually look.

For the multimedia presentation facility, simple black-box testing techniques will be used to ensure are parts are working correctly. First all components will be connected outside the enclosure to ensure all parts are functioning correctly. After this has been confirmed, the components will be assembled inside the enclosure and tested again.

2.1.6 End results of the project

The end product report, layout, and 3-D walkthrough have been completed successfully. The design, construction, and testing of the multimedia presentation facility is also complete.

3.0 Senior Design Facility Requirements

The senior design facility requirements section will provide a description of what is required for each section of the new senior design facilities. This section is broken down into the following sections:

Project workspace Tools Instrumentation and equipment Storage Meeting and presentation facilites Computer hardware Computer software Utility items

14

3.1 Project workspace

The first and foremost aspect of this project is to define the necessary workspace required for senior design teams to congregate and design their projects. This section is broken down into the following sections:

General workspace Test stations Mechanical workspace

3.1.1 General workspace

The general workspace is the space required for each group to make progress on its project. The general workspace is needed so groups can function in a controlled environment that allows them to complete work on their projects. Space will be provided by allowing each group to have its own space or shared space depending on the size of the project and its security requirements. Larger scale and higher security project teams will have designated work areas devoted solely to the project. Resources for the design and implementation of smaller projects will be found in the general project shared space or in two smaller rooms that can be reserved for project work.

3.1.2 Test stations

Test stations will allow students to test their project designs for accuracy and functionality. Testing equipment will include oscilloscopes, multimeters, general computer software, and project specified computer hardware/software. This workspace must be easily accessible for all senior design teams as well as having all necessary equipment, safety provisions, and proper instrumentation guidelines. Some of these test stations will be located on mobile carts. The mobile carts will be located within the two larger labs.

3.1.3 Mechanical Workspace

Mechanical workspace will account for project space needed for large shop tools such as drill press, soldering stations, and bench space/workstations regarding use of other hand or power tools. The workspace and tools must be easily accessible for all senior design teams as well as having all necessary safety provisions, and proper instrumentation guidelines.

15

3.2 Tools

Tools are a crucial aspect of the senior design facilities. A variety of hand tools, portable tools, and machine tools are necessary for teams to develop their projects. These tools will be located in two tool chests and within the designated mechanical workspace. A list of currently available tools can be seen in appendix A.

3.3 Instrumentation and Equipment

A variety of instrumentation and specialized equipment will be required for various teams to complete their projects. The instrumentation and equipment will allow teams to test and develop their projects within a controlled environment. General instruments include:

Power supplies Oscilloscopes Function generators Multimeters Counters RLC measurement

3.3.1 Power Supplies

The triple dc output supplies provide a necessary power source for specified projects. The power supplies will be located on the mobile carts.

3.3.2 Oscilloscopes

Applications of the oscilloscope are entirely dependent on the aspect of the project under testing. Oscilloscopes are needed to test the correct functionality of projects through measuring signal frequency, voltage, and current. The oscilloscopes will be located on the mobile carts.

3.3.3 Function Generators

Function generators are needed to provide a specified signal consisting of voltage, current, and frequency characteristics to a project. Function generators are usually used as an input signal for a project. The function generators can be located on the mobile carts.

16

3.3.4 Multimeters Multimeters provide a measured reading of voltage, current, or resistance between two “points/nodes”. Multimeters can be used to measure these characteristics of a project to test project functionality. The Multimeters can be located on the mobile carts.

3.3.5 Universal counter

Universal counters are used to accurately measure signal frequency. The Universal counter will be located on a mobile cart.

3.3.6 LCR meter

The LCR meter is a $10,000 piece of equipment used to read inductive, capacitive, and resistive characteristics for impedance testing. This piece of equipment is sensitive enough to read and balance contact resistance and capacitance. The LCR meter will be located on a mobile cart.

3.4 Storage

Many teams will have a designated area to store projects and project related materials. However projects are of varying sizes and as such, require different amounts of storage space. The following are the categories for storage:

Small storage Medium storage Large storage General storage Supply storage

All of the storage categories have the following in common:

Must keep the project secure from outside interference Must allow for all project contents to be kept together Must be accessible to all team members Must allow the workspace to be kept neat and organized

3.4.1 Small storage

This type of storage is for projects that could fit into a locker that measures roughly one cubic foot in size. These will be kept secure by a locking mechanism such as a padlock.

17

These storage units will be located within the major project workspace defined in Section 4.1.

3.4.2 Medium storage

This type of storage is for projects too large for small storage space but will still fit into cabinets that measure roughly 4’ X 3’ X 1’ and will be secured by a locking mechanism similar to small storage areas. These storage units will be located in the major project workspace and the main presentation lab defined in Sections 4.1 and 4.2.

3.4.3 Large storage Large storage areas will be needed for several of the ongoing projects and require a separate room devoted for each particular project. These will be secured my some sort of locking mechanism on the doors such as real-estate locks or numerical key locks. These storage areas are located in the large scale project rooms defined in Section 4.7.

3.4.4 General storage

This will allow for easy reference to former projects and project works. This will need to be a separate room that the administrators use to store this type of material for their future use. This room is defined in Section 4.5. As mentioned, access to this room will be limited to the administrators.

3.4.5 Supply storage

This is required for the storage of extra materials that are needed in day to day operations of the facilities, such as extra printing paper, solder, various reference materials for the equipment, and software programs. This could be located inside a lockable filing cabinet or some other general container that can be secured.

3.5 Meeting and Presentation Facilities

This section will describe the different meeting and presentation areas avalible for use by the senior design students. This section is broken down into the following sections:

Conference rooms Multimedia presentation facility

3.5.1 Conference rooms

Conference rooms will be utilized for design groups to convene with their advisors to discuss project progress and status. Conference rooms will require sufficient resources

18

such as seating and table placement to conduct meetings and to create or display documentation. Conference space will be provided within the reservable project rooms.

3.5.2 Multimedia presentation facility

The presentation facility will be used for project presentation through using special multimedia equipment. A review panel will use the presentation facility to evaluate the project and the presentation. Sufficient space will be provided for the review panel in the main presentation lab. The main resources that make up the multimedia presentation facility will include the following:

Multimedia housing Projector and projector screen Whiteboard and markers Table and chairs to accommodate the industrial review panel

The multimedia housing is the main feature of the multimedia presentation facility. The intended use of the housing is to enhance project presentations for senior design teams. The housing is a wooden framed podium containing a variety of equipment to enhance project presentation performance. The equipment contained within the housing includes:

Document projector (ELMO) Notebook tablet PC Sound system 4 channel wireless microphone system Desktop PC

The equipment provided within the housing will enhance the quality of senior design presentations. The 4 channel microphone system and speakers will enhance the sound quality. The notebook tablet PC and the ELMO will enhance the presentation quality by giving more options and control to the presenters. Spare cameras will also be used to record the presentation. The audio and video outputs of the equipment will be connected to a piece of equipment called the switcher/scalar. The switcher/scalar will allow the desired video output to be sent to the projector and the desired audio output to be sent to the speakers. The software program CAMTASIA will be used to record the presentation and provide a picture in picture format of the presentation. This will allow the audience to view the notes that the presenter is referring to as well as a view of the presenter.

The housing is designed to give the presenters the option to relocate their presentation to another room. It consists of wheels to make it mobile so it could be easily relocated into another room. Mobility is also supported due to the housing having one video VGA output to the projector.

19

3.6 Computer hardware

Computer hardware will be important to students creating their senior design projects. Currently senior design facilities include a mix of different types and ages of machines.

Because computer hardware becomes obsolete much faster than other types of equipment, it is recommended that all these machines be replaced before or at the time the new lab facilities are completed. The computer equipment purchased will need to meet the minimum system requirements for the University. In addition, it is recommended that at least 2 machines placed the large project workspace room and the main presentation room be high-end desktop systems for projects with higher processing needs. It is also recommended that at least one of the reservable meeting rooms include a higher end desktop machine, while the other room may include either a mid-range or higher ender-end desktop machine. Finally the large-scale project rooms should include two machines each. The type of machines may be determined by the type of project assigned to that room. Otherwise, it is recommended to include at least one higher end machine and one mid-range machine in each large-scale project rooms.

Because computer specifications change so rapidly, “mid-range” and “high-end” desktop will have to be defined at the time of purchase.

3.7 Computer software

The software available to senior design students needs to allow them to successfully complete their projects. From the survey that was completed, it was determined that the software currently owned by Senior Design is sufficient. Of course, in the future new versions and new software will be released, and it may be determined that new software would be useful, or required.

When new software is acquired, it would be best if licenses could be purchased for all of Senior Design’s machines. If this is not possible, the coordinators should try to evenly distribute software in all of the rooms used by Senior Design, with priority given to the major project workspace and main presentation facility.

A list of software currently available is included in Appendix B.

3.8 Utility items -Trash receptacles will be placed within all of the rooms. Recycling bins will be placed within the major project workspace and the major presentation lab. Telephones will be placed within the reservable rooms, the large scale project rooms, and the mail room. The mail room will include a paper shredder, copy machine, and a fax machine.

20

4.0 Detailed Room Descriptions

Following is a detailed description of each of the rooms that that make up the senior design facilities. This section is broken down into the following subsections:

Major project workspace Main presentation lab Machine room Mail room Administrative storage area Reservable rooms Large scale project rooms.

Unless stated under each sections description, all rooms will be accessible by current senior design students by a secure locking mechanism such as a numeric keypad. Schematics of each of these areas are located within each section.. A spreadsheet of all of the equipment needed for all of the workspaces will be located in appendix C.

4.1 Major project workspace

The major project workspace is where most of the project related work will occur. This lab is a 37’ x 18’ room. Within this space, teams will have access to the materials that are needed by each individual group. The eighteen small storage lockers, four medium storage cabinets, and two tool chests are all located within this area. In addition to the storage, four workbenches are provided for project use. Each workbench can, if needed, have a computer for project data storage and testing. Also located within this room are two of the mobile electronics carts. These carts allow the students to have test equipment readily available, and easily accessible. Also available for use is a four drawer filing cabinet that has reference materials for a wide variety of software programs and hardware user manuals. A soldering station will also be located within this space. There will also be a projector screen located above a white board.

5.2 Schedules

The key to a successful project is meeting deadlines. The following projected schedule for the completion of tasks and subtasks through December 2005 has been developed.

5.2.1 Project Tasks Schedule

The project spanned the length of two semesters with a break during the summer. The project schedule began in January and ended in early December. Figure 6 on page 31 depicts the original schedule with projected tasks and subtasks to be completed versus the proposed project calendar. The original tasks and subtasks are shown in blue. The technologies considered subtasks have not been completed according to the original schedule. Figure 7 shows the updated schedule with new deadlines for these subtasks. The revised tasks and subtasks are shown in red. The updated schedule was followed very closely which resulted in the actual schedule for the project shown in Figure 8.

6.0 Closure MaterialsThis section is broken down into the following sections:

Project evaluation Commercialization Recommendations for additional work Lessons learned Risk and risk management Project team information Closing summary References Appendix A

6.1 Project evaluation

This section describes what milestones were used, and how the project was evaluated for success.

For each milestone, a score will be determined from Table 10.

Table 10: Rating system used for the projectEvaluation ScoreMet/Exceeded Expectations 4Almost Met Expectations 3Partially Met Expectations 2Did Not Meet Expectations 1Did Not Attempt To Meet Expectations 0

At the end of the project, an overall score will be determined using the score and importance for each milestone. A final rating of three or better will be considered successful.

Below is a listing of milestones used for evaluation.

Milestone: Project DefinitionDescription: The project needs to be adequately defined in order for work to begin. This ensures the team members and the client agree on the scope and desired end product of the projectOverall Importance: 15%

Milestone: Technology Research and SelectionDescription: The team needs to research possible technology, equipment and layout for the design. Then selections must be made to best fit into the goals of the senior design coordinators, the department, and the team.

34

Overall Importance: 25%

Milestone: End-Product DesignDescription: The end-product design needs to detail the layout of the new senior design facility and be able to be implemented in the new building. It needs to be usable, meet all functional requirements, and come within budget.Overall Importance: 40%

Milestone: Project ReportingDescription: Project reporting will take place through the design process. This includes the project definition, project plan, project poster, end-product design, and final report. The final report needs to be usable and account for any changes made to functional requirements, assumptions, limitations, or design made throughout the development processOverall Importance: 20%

For the project, the scores were assigned as seen in Table 11:

Table 11: Score assigned to milestonesMilestone Score Weight Weighted ScoreProject definition 4 15% .6Technology research & selection 4 25% 1End product design 4 40% 1.6Project Reporting 4 20% .8

The sum of the weighted scores gives an overall final score of 4, a successful score for the project.

6.2 Commercialization

Although the end-product report is not suitable for commercialization, the multimedia presentation facility could be. The potential market for commercialization would include medium and large companies as well as universities. The final cost to produce and an estimated sale price has not yet been determined.

6.3 Recommendations for additional work

A number of recommendations for additional work on the project: Embedded systems station Website for tool checkout and room reservations

The addition of an embedded systems station would allow the creation of embedded computer systems, which are required in many senior design projects. This dedicated computer workstation would have all the tools needed to create an embedded system.

35

A website for tool check and room reservations would allow students to check out tools or rooms to be used for their senior design projects. This would help students be able to easily see what is available, and allow the senior design coordinators to easily track tools and help prevent tools from being stolen.

6.4 Lessons learned

During the course of this project the team felt its communications and teamwork skill worked out very well. There were rarely if ever any miscommunications, and, as is evidenced by our personnel resources, it was possible to distribute the work load well between the group’s members.

There were some difficulties encountered due to the unconventional nature of the project. For example, many times it was not easy to fit the project into the standard report and presentation formats, as many sections do not really apply to the type of project being completed. Another problem encountered was information availability. For the first semester the team could not obtain the final layout for Coover Hall. During this time work was done on designing the ideal senior design lab. Once more information became available, the team started working on the actual senior design lab.

The members of the team feel they gained a good amount of knowledge from the project including the use of SketchUp, the software used to create the 3-D walkthrough, and knowledge of combining audio and video formats. This was complex because each type of video must be scaled up or scaled down appropriately to the proper resolution, and combining the different types of video required a lot of knowledge and some unusual pieces of equipment. The team also feels that they learned a lot about project development and management. Large scale projects of this type require careful planning and documentation, and these are skills that were learned from this project.

Overall, the team feels the project went very well and no changes in approach would be made.

6.5 Risk and risk management

This section will explain the groups risk management and will be divided into the following sections.

Anticipated risks Risks encountered

6.5.1 Anticipated Risks

This section will discuss the risks that were anticipated at the beginning of the project:

Risk: Loss of a team member

36

Assessment: To minimize the impact of losing a team member all members will be kept informed of current progress of each other team member. Each activity will have a lead person and a backup.

Risk: The project will not meet expectations of the clientAssessment: All design requirements need to be determined as early as possible to prevent last minute problems that may be irresolvable. The client will be kept informed of progress and will need to review the project definition, plan, and other documentation to ensure satisfaction with the team’s progress.

Risk: The space provided will not be adequate to fulfill all the needs of the senior design studentsAssessment: In the case that the space needed to fulfill the goals of the project is not available; the first action necessary will be communication. If the situation cannot be resolved, the team will have to make a prioritized list of the needs, and communicating with the department and the team’s advisors, determine which needs could be eliminated in order to attempt to make better utilization of available space.

Risk: The budget provided will not be adequate to fulfill all the needs of the senior design students.Assessment: In the case that the budget granted to the project is not sufficient to fulfill the goals of the project, communication will again be the first step to resolving the issue. If communication fails, the team will again need to make a prioritized list of the needs, and communicating with the department and the team’s advisors, determine which needs could be eliminated in order to best use the funds available.

6.5.2 Risks encountered

The first risk encountered was not having enough space available in the layout for everything needed or requested by the client. This was managed as expected through communication with the client. Fortunately, in the final layout of Coover, senior design was allocated more space, and the revised amount was sufficient.

Another risk encountered but not anticipated was the addition in scope to the project. In April of 2005 our client added the creation of the multimedia presentation facility to the project. This was managed through redistribution of the team members’ workloads.

6.7 Closing Summary

Senior design classes provide ECpE students with their only opportunity to simulate a large scale team project. The projects allow students to apply what they have learned, and prove they are ready for an engineering career. The communications, team work, time management, and other skills learned in senior design are integral to a future engineer’s success in the workplace.

Because of the high importance of these classes, the facilities used by these students must be carefully planned to incorporate the needs of their projects and to help replicate a workplace environment. The team believes that the new senior design facilities will benefit students by allowing them to better research, implement, and test their projects. This, in turn, will help them become better engineers and lead to more successful careers.

The work that has been done will help ensure that the new facilities are utilized in the best possible way, and will help create a smooth transition to the new facilities.
