Persistence of vision Phi phenomenon:
In the phi phenomenon, a sequence of images causes us a movement sensation

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 - Risks
ID Risk Description Probability Effect Status Action
1 Project Management skill:
Team leader lacks of actual project management skill
High Serious Occurred
Team leader prepares knowledge from text book and ask for advise from experienced PM
2 Hardware knowledge:
There might be problems with hardware design due to the lack of knowledge in this area
High Moderate Potential
Ask for support from our supervisor and experienced acquaintances.

3 Human resource:
It’s hard to work together, as each team member has very different schedule.
Very high Serious Occured
Ask members to rearrange their schedules. After that find a time when everyone can work together
4 Human resource:
Some members still have to work at Fsoft, they could have to work over-time in the future
High Serious Potential
Add buffer time to the project plan.
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.

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).
