Babar Moghal
3. Fielded Project
4. Second Phase Objectives Lightning Detector
Design and construct lightning detector circuit
Interface with a computers serial port
Log each lightning strikes date and time into a data file
1 minute interval minimum between strikes so 1 lightning strike isnt counted more than once
Network wide data capability (Website)
Take weather software and lightning data files and post information on website
Graph and Plot Data using Excel
5. Lightning Detector
6. A snapshot of the circuit
7. Where are we now We have gathered all the parts and components and built a prototype circuit
We are currently testing and debugging the circuit
We have a plan to finish by semester end
8. Gantt Chart
10. Where we are going We have to continue further testing and check for the correct output
With the completed circuit we will interface with a computers serial port
A data file will be made with the date and time of each lightning strike
11. Where we are going Website will post links to download both weather station and lightning detector data files
Website will be host of current weather variables
Skeleton excel file will be made so students can import weather data to view graphs and figures
12. PENDULUM PROJECT
13. Purpose To demonstrate and help understand the physical Concept of Pendulum motion to the high school students
To produce three working pendulums using electromagnetic force, optical sensors, stopwatches, circuitry, and a car race track to create students interest in engineering
14. Basic Principles Explained Helps in understanding if frequency changes with
changing length of the pendulum
changing the mass
by the use of stopwatch and the race-car track
15. Proposed Shape of Pendulum (Fall 2004) T-shaped one piece metal rod that is hung from the beam by metal brackets. Ball bearings between rod and brackets reduce friction considerably
16. Plans for Spring 2005 Use a T shaped one piece metal rod supported on a knife-edge to reduce friction considerably
To account for the small angle approximation, use a spring at the top of the pendulum
Use the optical sensors on the side instead of putting them below the pendulum
17. Questions that need to be answered When will Pendulum frame come back from Womens Prison

Circuit board missing (1) (at Smittys)
Stop Watch missing (1) (at Smittys)
18. Things Not Working Stop Watch
Solenoids not able to hold the Pendulum
Circuit
Connection with the race-car track (unknown)
19. Motorized Cart Michael Y. Chung (Project Leader)
John Beasley
20. Problem Identification Physically challenged students have a difficult time coordinating their bodies
They are not able to use the regular physical education classroom 4-wheel carts due to their inability to coordinate their feet
Mrs. Angela Sutton teaches a class of physically challenged students at Amelia Earhart Elementary School
Motorized carts are needed to assist the students in maneuvering around the wooden gym floor in a similar fashion to the 1 x 1 4-wheel cart
21. Objective To design a device that assists a physically challenged student to interact in an elementary school physical education (P.E.) class
Sub-Objective
To design and construct a motorized cart which allows the physically challenged student to maneuver on their own while ensuring safety
22. Current Status Upon reviewing the project status from fall 2004, the motorized cart project team has decided to start over with the Problem Identification Phase of the EPICS Design Process
Problem Identification Phase Tasks
Identify the problem
Determine project objectives
Determine motivation for the project
Identify outcomes or deliverables
Determine duration of the project
Identify community partner contact
23. Current Status Important Dates:
January 24, 2005 5:30 PM PHYS 114
Meeting with Fraz Ahmed and Mukund Raghu (previous motorized cart project members) with current motorized cart team members Michael Chung and John Beasley
Questions were asked regarding the concluding status of the motorized cart project from fall 2004
January 28, 2005 12:30 PM ME #87
Meeting with Professor Galen King with motorized cart team members Michael Chung and John Beasley
Questions that were to be asked to Mrs. Angela Sutton were brainstormed and conferred
January 31, 2005 8:00 AM Amelia Earhart Elementary School
Meeting with Mrs. Angela Sutton with motorized cart team members Michael Chung and John Beasley
All customer specifications were acquired and noted
24. Current Status Customer Specifications (Results from Mrs. Angela Sutton)
Students are roughly 3 feet tall and under 50 lbs.
Cart will be used on a wooden gym floor where students can move/roll around
Slow speed (roughly walking speed)
Children have physical disability where they cannot coordinate the body all at the same time (but hands can be coordinated)
Most likely a joystick will be needed for maneuvering
Storage of cart can be either upright or flat
Motorized cart will be used for a duration of 30 minutes and twice a day
Project will be a continuing use for ongoing years
Indoor use only
An emergency stop function for the teacher would be beneficial
The cart should be manageable to move around
Flat area use only (no ramps)
Velcro straps will be required to secure the student in the cart
Child should be oriented either in the sitting position of laying down on their stomach
28. Current Direction of the Project The motorized cart project team will be entering the Specification Development Phase Tasks
Complete users and beneficiaries analysis
Evaluate design constraints
Develop engineering specifications
Compare benchmark projects
Determine design targets
