  5. 318-595 Capstone Project Team #3: Total Resources • 1000 Manhours • $500 or key part availability for material and prototyping

  6. 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

  7. 318-595 Capstone Project Roles to Define & Assign • Lead Project Integrator (LPI): Dave Worden • Lead System Designer (LSD): Patrick Staley • Lead Presentation Manager (LPM): Dan McGowan • Lead Report Manager (LPM): Josh Zagorski • Lead Manufacturing Mgr (LMM): Paul Baierl

  8. 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 • Blocks: • Power supplies (one for the sensors and one for the display) • Wireless Communications • Display interface • Sensors and interface • Logic and activators

  9. 318-595 Capstone Project 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

  11. 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. 318-595 Capstone Project Project Idea #3

  15. Selection Matrix

  16. The WinnerRadio Direction Finding System • We chose this project because: • Familiar Technology. • Ability to produce working prototype. • Components are inexpensive and readily available. • Data is not process intensive. • There are no other economical products on the market. • Unique application to rocketry and RC aircraft

  17. Radio Direction Finding System • Major Risks in Project • Interference and/or reflection of signal • Correct antenna selection • FCC Regulations transmission signals • Signal/Data Processing

  18. 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 • Logiq 9 Video Card • Lots of programming involved! • Lack of time / lack of knowledge • Unanimously Supported • YES!

  19. Radio Direction Finding System • The RDFS will allow the user to locate rockets and RC aircraft. • The RDFS is a two part system. • The User holds the receiver and places the transmitter inside the rocket or RC aircraft.
