Electrical Engineering/Computing EngineeringSenior Design Project
The Senior Design Project
The project is a CAPSTONE requirement because it allows you to apply the analytical and synthesis skills you have developed during your undergraduate coursework and appreciate how different areas of the curriculum relate to each other.
It involves- Identification and analysis of a real problem- Design of a hardware or software solution- Construction of the solution
It should be done as a team of 2-4 students
It can be multiple terms

In-store Promotional Display Tracking using RFID Technology
Brandon Cole, Sam Taggart
Sponsor: Norm Elliot, GSK
Advisors: Dr Mickle
Dr. Marx
Purpose: To recommend to GSK a gen-2 RFID tag to replace the tag that they currently use to track their promotional displays.
Benchmarks: Performance of tags, both in air, and attached to the displays, as measured by power consumption, and read distance will allow us to determine which tag is least affected by the cardboard and presents the best readability.
Tags Tested:
Symbol:RFX6000 Series 2” x 4”
RFX6000 Series 4” x 4”

Symbol 4 x 4 – in air
Symbol 4 x 4 – on Sensodyne Display
Test procedure: Test each tag both in air and attached to each of the 4 displays that we were given. Align the display and reader so that the maximum amount of interference would occur. Record power consumption and read distance at each frequency.
Results: The Symbol tags outperformed all of the other tags that we tested. The graphs at right show how the frequency response of the Symbol tag was affected minimally by the Sensodyne display.

Interactive Radio Station Exhibit for the Children’s
Museum of Pittsburgh
Objectives:
Educational Design
Receiver Design
Coverage Area (Professional):
Coverage Area (Kit):
Transmitter• FCC Part 15 Compliance
• AM vs. FM transmission
• Propagation Method
Receiver• Interactive • Educational Value
• Cost • Sustainability
Commercial professional and educational kits were tested with the transmission system described. The professional radio significantly outperformed the radio kit in terms of audio quality and coverage. The receiver design includes the use of a high performance stereo FM chip used in consumer products such as mobile phones and MP3 and CD players. Because of its excellent performance characteristics, it is expected that the receiver will perform more similarly to the professional receiver.
Transmitter Design
A PowerPoint presentation was created to explain the basics of radio and FM to children. The educational material will be used in conjunction with the receiver kits by museum staff to teach the children.
A RadioSign FM Transmitter was selected because of its compliance with FCC Part 15 power regulations. Upon testing, it was determined that the FM transmitter from the radio station to the desired area of coverage was too weak; therefore, a UHF link was implemented
A handheld, cost effective, educational receiver was designed. The RF, IF, and detection stages were placed within a closed box which plugs into a base box containing the power supply. To incorporate a hands-on educational aspect, the audio amplifier was designed to be constructed by children
The Saturday Light Brigade is a weekly radio program produced by the Children’s Museum which is broadcast over FM radio on Saturdaymornings. The objective of this project was to design, build and implement an educational, interactive radio exhibit to allow children to tuneinto a looped broadcast transmitted within the museum throughout the week while learning about radio.
on a breadboard. All sections of the receiver are hard-wired to each other within the base box.

[Chairman, ECE Dept.]
Purpose: To develop a tunable white light device using red, green and blue LEDs for commercial/industrial building applications.
Justification: Energy savings; Emulating sunlight (progression of peak wavelength) increased productivity/morale in workers; Faster learning, higher test scores for students; Faster recovery time in hospitals.
Any color can be matched by a linear combination of three other colors: R, G, B:
C = aR + bG + cB

Teams
• Teams should not be homogeneous– Analytical / Experimental / Prototyping Skills
• Teams always have a leader– It may move around
• All team members need to be given a chance to contribute
• Teaming skills are not trivial• The grade is essentially a group grade
Electrical Engineering/Computing EngineeringSenior Design Project
Funding
There will be limited funding for hardware available through the Department.
Groups can include in their proposals a request for support for any significant major equipment or supplies, including a justification of why it is needed, who the vender should be, and an estimated cost.
The equipment or supplies will normally remain the property of the Department at the conclusion of the project.
