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)

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
