Team #3: Total Resources
• 1000 Manhours
• $500 or key part availability for material and
prototyping
318-595 Capstone Project
Team #3: Decision Making
• We will make decisions based on a group consensus
• If teams cannot make effective decisions according
to their agreed upon guideline, they may appeal to
their Lab Assistant and upwards to the Prof/Lect
• The Prof/Lect has the final call on any team
decision

318-595 Capstone Project
Project Idea #1
• Automatic Pool Cleaner
• Add chlorine or ph balance depending on ph level, turn on pool filter
depending on turbidity. Save time on testing ph of pool and adding
chemicals, and save money on electricity by only running filter when
needed. Also water temperature sensor to let people know the
temperature of their pool.
• Plug-in to wall outlet, keypad and LCD interface for programming and

Project Idea #2
•Radio Direction Finding System
•This project will be used for locating:
–small rockets
–radio controlled aircraft
•The Transmitter will radiate a signal. The Monitor will receive the signal
through a directional antenna and circuitry providing location data. The
location data may be displayed in analog, digital, or audio fashion.
•Small physical size and weight, Low power consumption, Portable,
Minimum ½ mile detection radius, Indicate direction and distance,
Frequency counter or modulated signal.
•This rocket retrieval system is an excellent design project
–All technology required for design is known
•Many circuits are available to use as is Transmitters and Receivers
–All components are inexpensive and available

Project Idea #3
•
•
Automatic Fish Feeder
Proximity sensor detects fish near the feeder which in turn causes food to be
released.
–
–
–
–
–
–
•
Submersible (possibly)
Power supply to last a week (possibly solar)
Logs various data while deployed
Can equip with temperature sensors, date, and time
Precision motor control
Can use IR, laser, or acoustic sensor
This would be a good senior design project for our group because this is a device
that does not currently exist, but could yield important data about the feeding
habits of fish.

Project Idea #4
• GE Healthcare L9 Ultrasound Video Card Conversion
• Combine AGP Video Card and PCIDGVIC into one board.
• Requirements:
– 1280 x 1024 & 1024 x 768 Digital Video output
– 800 x 600 Analog Video Output
• Power sources would be defined by motherboard inputs
– Can be modified for board use
• User Interface would be through the CPU
• Need to include: Schematics, Requirements, FPGA work, Signal
Integrity, Highspeed Data Transmission, Digital and Analog Design,
Software, Drivers, Layout, Power Supplies, Power Up Sequence,
DaVinci Software.

–
–
–
–
Interference and/or reflection of signal
Correct antenna selection
FCC Regulations transmission signals
Signal/Data Processing
Radio Direction Finding System
• Why were other projects rejected?
– Automatic Pool Cleaner
• Lead time / availability of sensors
– Fish Feeder
• Non-familiarity with optical sensors
• Data is process intensive
