Overview of Status of Analysis, Design, Fabrication, Tests, etc.
First functional prototype base plate and PCB were redesigned to accommodate USB 3.0 connections and footprint.
Accomplishments from Previous Week
Order baseplate, PCB components - Harald
USB/Locking mechanism redesign requires different parts, ordering will take place asap
Order PCB before end of this week - Leigh
USB 3.0 standard redesign, USB 2.0 design scrapped
USB 3.0 redesign requires only minor changes, base design principals remain constant
Figure out way to incorporate buckle lock into one of the U-dots - Jesse/Trent
Buckle lock design presented too many manufacturing issues re: assembly
New design incorporating a "plunger lock" in preliminary stages, see attached sketch
Start CAD for buckle lock after implementation is figured out - Jesse/Trent
Locking mechanism redesign precluded completion of this line item.
Goals for Next Week (list names after each item). Use specific and measurable objectives.
Redesign base plate to accommodate USB 3.0 footprint - Harald
CAD for locking plunger design - Jesse
Redesign base plate for plunger accommodation - Trent
Purchase redesigned PCB incorporating USB 3.0 - Leigh
Sponsor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
USB 3.0 implemented as the default standard due to backwards compatibility and updated communications standards.
Decision to design a dummy load to simulate a cubesat for demonstration purposes, which will incorporate some form of easily distinguishable power and data transmission.
Instructor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
Threadserts suggested for aluminum to aluminum connections
Redesigned baseplate to eliminate the need for threaded aluminum connections.
Will incorporate threadserts if aluminum threads are required.
Comments from Other Students in the Class (indicate date of comments and if via email or in person)
Fatigue/Vibration analysis based on the launch profile for the vehicle.
Risks and Areas of Concern
Redesign of locking mechanism and PCB adds extra time to the project.
Resources or Information Required but not Available
N/A: No longer working with EXOS means we have more freedom in our design
Schedule
Describe upcoming milestone
Update Gantt chart.
Budget (list amount spent and amount remaining)
