Whats Completed

• Feb. 28Mounted rabbit socket above sensor
  circuit.Began on sensor array.
• Feb. 25Built the sensor circuit.
• Feb. 24Began on circuit layout for the sensor
  circuit.
• Feb. 22Analyzed that the motor-driver wasn't
  properly working due to three burnt mosfets.
• Feb. 20Tested and began debugging of
  motor-driver circuit.
• Feb. 19Built motor-driver circuit.
• Feb. 18Went to IC supplies in order to obtain
  connectors for motor-driver circuit. Built
  chassis for out mouse.

Sensor Array

• Adjustability
• Vertical adjustments of 0.5cm
• Horizontal Adjustment (if possible)
• Still in progress/planning
• Separate connectors
• Non-soldered sensor connections
• Circuitry NOT located on the array
• Leaves a light array

Sensor Array

• Sensors are labeled in terms which will be used
  in the coding.

Incomplete Tasks

• Algorithms
• Coding
• Mounting of the Sensor Array
• Combining all the separate pieces
• Debugging
• Really Debugging
• Extreme Debugging

Future Thoughts

• Problems/Outstanding Issues
• The completed sensor circuitry may malfunction
• Soldering
• Burnt Chips
• Broken Mosfets, etc.
• Programming Errors
• Communication and Teamwork Problems
• Not completely visualizing the problem(s) that
  may occur
