Overview of Status of Analysis, Design, Fabrication, Tests, etc.
PCB design is finalized
Additional features will either become modular or suggested in final report (Thermocouple, micro SD card, etc.)
Software design is underway
Final hardware design has been updated
Final hardware will be manufactured and assembled this week
Final test will be scheduled sometime tenth week with sponsor
Accomplishments from Previous Week
Final Design Presentation given (18-May-2015)
Pressure vessels of various diameters tested (19-May-2015 --> 22-May-2015)
Second Draft of Report submitted (21-May-2015)
Water-sealed gland tested dynamically in pressurized environment (22-May-2015)
Axial force of release mechanism tested (22-May-2015)
Final PCB design reviewed by electronics contact at SPAWAR, Alex Phipps (22-May-2015)
Modified Design completed (23-May-2015)
Quoted price for three boards estimated at $240
Goals for Next Week (list names after each item). Use specific and measurable objectives.
Release final PCB design (Mike)
Secondary electronics objectives will feature modular design and be suggested in final report
Create memory storage interface and installation/setup UI for programming timed release (Katherine)
A MATLAB/python GUI will be considered/designed
Create final pressure vessel and release mechanism (Alvin and Matthew)
Sponsor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
External storage like a micro SD card could be suggested in future improvements to system (22-May-2015 during meeting)
An alternative to teflon tape might be plumber's compound (22-May-2015 during meeting)
On the issue of flooding in pressure vessel, test different sealants without the gland in order to validate each method (22-May-2015 during meeting)
Make sure to use a wrench while installing the threaded pipe caps, because any extra engagement of threads will make a difference under pressure (22-May-2015 during meeting)
Create assembly/fabrication instructions which can be followed without necessarily going too much into technical detail (22-May-2015 during meeting)
Assuming the final parts have been machined from the released drawings, it should follow that assembly can be done by reading the assembly instructions section in the appendix of the report
Coordinate final testing time and location (22-May-2015 during meeting)
Instructor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
If the motor is only going to be on for at most thirty seconds, then thermal heating should not bee too large of an issue (18-May-2015 during presentation)
Comments from Other Students in the Class (indicate date of comments and if via email or in person)
We should be able to give a rated accuracy of time with the real time clock (18-May-2015 during presentation)
