Project Plan, Task Checklist, Estimates Project Prototyping

1. Project Plan, Task Checklist, EstimatesProject Prototyping • Objectives • Introduction of Project Checklist Estimate Spreadsheet • Compile Project Plan, Estimates, Gantt Chart • Introduction to Prototyping Techniques • Determination of Best Prototype Strategy • Introduction to Circuit Board Layout - Exercise • 3 Major Deliverables • Team & Individual: Overall Project Plan (due for P2) • Team: Prototype Plan • Individual: Schematic and Layout Exercise: Thermal Sensor Circuit

2. Project Plan, Task Checklist, EstimatesProject Prototyping • Deliverables - Individual and Team • For Each Block Owner: Completed Excel template for Block Level Tasks • For Each Block Owner: Create Block Line Info for Team Level Prototyping Summary Plan • For Each Team: Completed Excel task template for Project Level Tasks with Block level tasks integrated for project totals • For Each Team: Summarize your overall plan on 1-2 Powerpoint Slides incl Gantt chart

3. Project Plan Summary Templates Suggested Overall Project Plan Summary Slide Contents • 1st Slide: Estimation-Reconciliation Summary • Total Manpower Estimated vs Available (from lab 1) • Total Material $ Estimated vs Available (from lab 1) • ~ % of total manpower for system design tasks, detailed design tasks, verification tasks, and documentation tasks • Suggested down/up scope if needed • 2nd Slide: Project Plan Graphical Summary • Create single page high level GANTT chart for entire project • Show chronological interdependencies (example: can’t prototype until parts are procured, can’t procure parts until part list is compiled, etc)

4. Excel Task Estimation Tool • Project Level Task Estimation Sheet • Manhours Totalize at bottom of Sheet • Material $ Totalize at bottom of Sheet • Data Is Entered into Beige Shaded Blocks Only ! • Start/End Date should be realistic and be dependent on other tasks • Use Week.Day Numbering (ie. Class Week #, Monday=1, Sunday=7) • Example: 4.4 = 4th class week, Thursday • Customize for your own use by • Number of Design Blocks • Cut/Paste the Detailed Design Section for Each Block Owner • Use as Project Plan for Tracking Team Members to Weekly Deliverables

5. Excel Task Estimation Tool • Project Level Task Estimation • System Design Tasks • Detailed Design Blocks from Next Sheets • Material $ and Manpower Hrs Totalize in the Green

6. Excel Task Estimation Tool • Project Task Estimation Tool • Verification & Integration Tasks • Presentation, Report and Validation • Manhours Totalize at bottom of Page • Material $ Totalize at bottom of Page

11. Basic Electronic Assembly and Test • Deliverables – Individual: Develop the schematic and layout files for the Example Thermal Sensor Circuit to exactly match the layout shown. The PCB design should encompass the following requirements • Dimensions of 1.5” x 2.2” • 2 Layers (double sided) • Through Hole + 1 SMT Part • Placements as Shown for all parts • 25 mil power & ground traces, 10 mil signal traces • 56 mil power & ground input pads with silkscreen Labels • 56 mil output signal pads ExpressPCB is suggested due to simplicity and tutorials

12. Basic Electronic Assembly and Test • Deliverables – Individual: Compute the board cost. Capture Itemized Popups • Keep Dimensions of 1.5” x 2.2” • Layout  Compute Board Cost (Use Lowest Cost Option) • Capture Itemized Cost Popup in a Powerpoint Slide • Revise your Board Dimensions to 3.8” x 2.5”, Recost using special • Capture Itemized Cost Popup

14. Example: Temp Sensor Circuit • 3 ICs: LM35 SO8, OP07 Dip 8 • 6 Capacitors: Ceramic Monolithic Axial • 3 Resistors: 0.125W Axial 10 Total Nodes
