  6. Team #1: Weekly Project Meeting Plan • Mandatory Weekly Meeting : IEEE office, Thursday 5 - 7 PM • Emergency Weekly Meeting 1: IEEE office, Friday 12 - 4 PM • Emergency Weekly Meeting 2: IEEE office, Sunday 10AM - 1 PM Note: Meeting Owners Send Weekly Email Notices, Record Business-Issues-Actions, Keep Weekly Attendance Records

  7. Team Fundamentals Resources • 780 Resource hours (calculated at 12 hours per week per person for 13 weeks) • $250 (calculated as $50 per team member) Decision Making • We will attempt to reach a consensus for all decisions, in the event that we are unable we will make decisions based on majority rule.

  8. Proposed Projects • Cellular Automotive Door Alarm • RF Triggered Pet Access Door • Electronic Musical Instrument

  9. Proposed Project No. 1 Cellular Automotive Door Alarm Key Features • Sensors located across from each other, one on the door and one on the frame. • Microcontroller is activated by power door locks. When door is opened and the controller is active, the transmitter sends a text message to a specified cellular phone. Requirements • 12.4 volt battery • Transmitter flexible with cellular standards Justification of Dismissal • Unable to clearly define how to design the transmitter • Cellular technology differs too much

  10. Proposed Project No. 1 Cellular Automotive Door Alarm Power Supply CELLULAR CONTROLLER Microcontroller Power Locks Sensors Transmitter Receiver/Cellular Phone

  11. Proposed Project No. 2 RFID Triggered Pet Access Door • An access door for a pet that would unlock to allow the pet access through the door. • Triggered by tag embedded under the pets skin. • This tag is available for tracking lost pets and is already widely distributed. • No need for a separate collar that could be lost. • Allows pet owner to determine if the pet is in or out. • Would run on AC power and have a user friendly interface with LCD display to instruct user on setting up the device. • Also manual unlock button. • Only one block outside of current areas of expertise to promote high probability of success.

  12. Proposed Project No. 2 RFID Triggered Pet Access Door Controller Input/Output Buttons / Beeps Output – RunningLED Reader Control Transmit/Receive of Antenna Mechanicals Lock On/Off, Door Design, sensors Antenna (including cable to Reader) Power Supply / Conversion

  13. Proposed Project No. 3 Musical Instrument (Analog Synthesizer) • Unique interface provides unique control over sounds • Digital effects processing for timbre control • Analog effects for even more timbre control • Modular nature of this project allows for flexibility of scope

  14. Proposed Project No. 3 Musical Instrument (Analog Synthesizer) • Interface • Selects different voltages corresponding • to different musical pitches • Low Frequency Oscillator • Creates audio signal from interface voltages • Power Supply • From 120v or battery to supply power to the other blocks • DSP Effect • Performs wave-shaping using DSP • Analog Effect • Optional “overdrive” effect using analog circuit

  15. Project Selection Process • Evaluate Proposed projects (3) • Feasibility Assessment • Interest • To bring the project choices to two • Majority Vote • 3 to 1 in favor of the Instrument • Dissenting vote based on skepticism of project feasibility. • Risks • Failure • To produce sounds. • To implement interface successfully. • To mix signals.

  16. Selected Project • A musical instrument • Enables user to produce varied sounds with effects • Unique interface • Unique sound production • New variation on synthesizer • Requires both hands to play Musical instrument driven by touch sensitivity to produce electronic sounds
