In this design review, you will show, as applicable for your project:
Complete populated PCB(s)
Basic functionality of all of your electrical/computer systems by using basic device drivers
Characterization of your power supply
Models/prototypes of all mechanical systems
All parts will be properly placed and soldered on your PCB(s).
You will demonstrate working models/prototypes of all mechanical systems. The models/prototypes must demonstrate that the key concepts of your project will work properly when fully built. Examples:
Drivetrain: Demonstrate that motors/actuators/etc. can
successfully produce the desired movements
Filtration: Demonstrate that the mechanical filter can produce a clearer output
fluid
Thermal: Demonstrate that your thermal conduction systems can transfer heat
Strength: Demonstrate that your system can meet strength requirements (CAD
models are acceptible)
You will demonstrate that all of your digital and analog hardware devices are "alive" by showing basic functionality. For digital devices, this means writing basic device drivers. For analog and mechanical devices, this means showing correct basic operation.
Basic device drivers will have been written for all hardware devices. These will be used to confirm that all hardware is functioning at a basic level. Your team will demonstrate that all hardware and device drivers have basic functionality during the design review. Some examples of "basic functionality" are:
ADC: Demonstrate that the microcontroller can read an input from
ADC using the ADC driver and that it changes when the input voltage is varied.
DAC: Demonstrate that the microcontroller can vary the output of the DAC using
the DAC driver.
LCD: Demonstrate that the microcontroller can use the LCD driver to display a
character or point on the LCD.
LED: Demonstrate that the LED can be turned on and off using the LED driver.
Buttons: Demonstrate that the action of buttons can be read by the
microcontroller using the button driver.
Amplifiers: Demonstrate that a small signal becomes larger without unreasonable
distortion.
Filters: Demonstrate appropriate attenuation/gain using a function generator.
Your team will have completed a complete characterization of your power supply(s). Your team will demonstrate the power supply(s) working with an output voltage within 2% of the spec'd output voltage at the expected load for your project.
Your team should have turned in the following documents by 11:00 AM on the day of the review, as applicable:
Device Driver Specification
Power Supply Characterization
Schedule with up-to-date progress marked - email to instructor
All team members must be present at all design reviews. Students with unexcused absences from design reviews will receive a zero grade for the design review.
All team members should be familiar with the basic operation of each subsystem and with the basic performance of the power supply. Each team member should be intimately familiar with the software/hardware for at least one subsystem.
Categories (below) will be weighted according to their importance to your project.
Complete populated PCB(s)
Basic functionality of all of your electrical/computer systems by using basic device drivers
Characterization of your power supply
Models/prototypes of all mechanical systems
