1. Introduction Title page Statement of Purpose (Motivation) Project title, group members, TA, date, course # Statement of Purpose (Motivation) Why did you select this project? Objectives Goals: What problem is being solved? Functions: What is the product supposed to do? Benefits: How is it good for the consumer? Features: What aspects make it marketable?

Example: Swim Pace Aid Objectives Goals Functions Benefits Features Improve athletic training and coaching for swimmers Functions Light a sequence of LEDs at a set pace to guide swimmers Benefits Provide real-time visual indication of pace to swimmer Features LED panels submergible in up to 2.5 meters of water Lap pace ranges between 8 and 45 seconds, 0.5 second increments

2. Design Block Diagram Block Description Modular Interconnections Consider high-level and detailed-level diagrams (example on website) Block Description Matches block diagram 1-1 Describe function of each block Contribution to overall system Interconnection Functionality Use quantitative, specific language Summary of system followed by specific descriptions

Example: Swim Pace Aid

Example: Swim Pace Aid Power Supply Not quantitative The power supply will provide power for all of the components in the system. The power supply will consist of 3 AA batteries wired in series to provide a 4.5 V voltage source. The power supply will have reverse voltage protection in the form of a MOSFET reverse voltage protection circuit. The MOSFET circuit is a much more efficient alternative to a diode reverse polarity protection circuit and will increase the lifetime of the batteries in the voltage source. A low dropout regulator (LDO) or linear regulator will be used to step down the voltage source voltage to 3 V in order to provide power for the microcontroller and communications modules. The voltage at the output of the reverse polarity protection circuit (~4 V) will be sent to the LED module. Not quantitative

Requirements and Verification At least one per block Concise and specific – don’t need full sentences Define functioning behavior Project should work if all requirements satisfied Verification Test procedure for each requirement Quantitatively define “passed” test Describe how results will be presented (i.e. tables, graphs)

Example: Power Supply Requirements Verification Power Supply must provide 12 V ± 0.2 V at output. Connect output of the power supply to multimeter. Check that output voltage falls within spec. The measured value will be presented on a number line with specified voltage range indicated. Quantitative values on this side

Tolerance Analysis Critical part of the design process Pick 1 significant component of your design Why is this component significant? What is an acceptable tolerance and why? Relate back to requirements on that module What is the test procedure? How do you check the component is operating within that tolerance? Use quantitative language If I choose resistors with +/- 10% tolerance, will the resulting variation in gain of my amplifier be within spec? Tolerance analysis isnt an experiment done after the project is constructed to find the tolerance of some parameter. At any point in the semester: Test this component at the extremes and include results in lab notebook and final report.

4. Cost and Schedule Cost Labor = (Ideal salary) * 2.5 * (hours to complete) Sum labor costs for each partner in the project, to compute the total labor cost Parts = Sum of cost of all parts Include part # GRAND TOTAL = LABOR + PARTS

Example: Swim Pace Aid Person B Person C Person A

Example: Swim Pace Aid

Keep careful track of all costs and schedule changes along the way—you’ll need them for the final report!

Schedule Use the modularity of your design to allocate responsibility Weekly time-table outlining project completion Only one person responsible for each task At least one task per week per person Responsibility ≠ workload Define tasks in terms of deliverables Research and ordering parts not considered weekly tasks (by themselves) No "To be determined" weeks Be SPECIFIC Use the modularity of your design to allocate responsibility

Example: Swim Pace Aid Person B Person C Person A
