Summary of any changes to overall design, costs, schedule, or risks as a result of the preliminary design.

Part A: Preliminary Design Documents
You should first complete the Preliminary Design:
· Any functional blocks which were not designed in week 1 should be designed.
· The software flow charts should be completed and critical software written.
· Subsystems which can be simulated should be simulated to verify the designs. If designs do not work, changes should be made.
· Critical software should be tested to the extent possible.
Narrative of design methodology for various functions along with resulting design schematics.
· Results of simulation
· Narrative explaining the software architecture and results of tests of any coded software
· Summary of any changes to overall design, costs, schedule, or risks as a result of the preliminary design.
· Appendix A: Design calculations and circuit analysis calculations. Voltage, current, and power for all electrical components should be considered in the analysis to make sure you don’t exceed the component’s capability. If a microcontroller is used in the project, include controller power requirements, input / output voltage and current requirements as well as the circuit analysis involved with connecting the external devices to the microcontroller (example specification: the programmed output port for controller X can source a maximum of 100mA of current at 5 volts Vout). The information from the specifications will aid in determining how to connect external devices. This information will go in Appendix B of your final report.
· Appendix B: Detailed software flowchart
· Appendix C: An updated list of components. At this point, the list is just a table with three columns: Item Number (1, 2, 3, etc.), Part Descriiption (ex. 100 ohm resistor), and Quantity.
Note that the component selection document will be finalized and updated after the circuit or system is built and tested. Thus, it is expected that minor adjustments will be made to the component values initially chosen in order to achieve the desired outputs.
Part B: Role of Physics or Other Sciences (This will also be included in your final project report as this is used for assessment of your understanding of the scientific concepts and calculations underpinning your project.)
Write at least several paragraphs addressing in a technical and non-superficial manner:
a. the role that physics or other scientific concepts play in the operation of your project
b. how the mathematical treatment and design of your project relies on mathematics/equations associated with physics or other sciences.
