4.  Persistence of vision  Phi phenomenon:  In the phi phenomenon, a sequence of images causes us a movement sensation Introduction - Ideas FDA Team

5.  Beta movement  The LEDs, electronically, are individually controlled, but our eyes and brains perceive them as a snake running clockwise around the four edges of the square picture Introduction - Ideas FDA Team

FDA Team Introduction - Risks IDRisk DescriptionProbabilityEffectStatusAction 1 Project Management skill: Team leader lacks of actual project management skill HighSeriousOccurred Team leader prepares knowledge from text book and ask for advise from experienced PM 2Hardware knowledge: There might be problems with hardware design due to the lack of knowledge in this area HighModeratePotential Ask for support from our supervisor and experienced acquaintances.

Very highSeriousOccured Ask members to rearrange their schedules. After that find a time when everyone can work together 4Human resource: Some members still have to work at Fsoft, they could have to work over-time in the future HighSeriousPotential Add buffer time to the project plan.

10. Functional Requirement  Customized power supply unit can provide enough electricity to the whole system.  Rotate the circuit board by a motor at a speed of at least 1400 rounds per minute.  The system can turn on/off the LEDs properly, so that we can see the illusion of an analog clock with three hands: hour, minute, and second.  Display multiple colors (optional). Use RGB LED to create multi-color illusion.  The system can radomly switch its display way, user also switching manually using remote.  When the main power is cut, the system will use a small integrated pin to keep timing. When the main power is on, the system will display the right time. FDA Team

11. Non-Functional Requirements  “Propeller Clock” system must display correct time over operating time. The different time must be less than 1 second after 24 hours of running.  When the “Propeller Clock” system operate, the noise should be small so that it will not disturb users.  The numbers and clock’s hands must be clear and easy to see.  The hands of the propeller clock must have different size, so that we can distinguish each one.  The system can operate normally in a normal living environment (study room).
