Overview of Status of Analysis, Design, Fabrication, Tests, etc.
Immediate focus has been on securing the longevity of the pump by eliminating the voltage spikes that occur while multiple components are active at the same time, such as the cart, the fans, and the pump.
Leaks from the water tanks corroding the pump are to be looked at next. However, the tank in question is not available.
Concept sketches of a universally adjustable mounting system for the moveable misting head/fan combination have been made.
Accomplishments from Previous Week
The voltage spikes from the converter have been addressed within the self-contained misting system through means of a filter.
A cheaper pump has been found that still provides the 80 psi used in the misting system.
Goals for Next Week (list names after each item). Use specific and measurable objectives.

Sponsor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
Two mister designs, one for each major cart model, would be fine, but one is the ideal result. (3-23-17 in person meeting)
We will look into (sketch/CAD) creating a single design that looks good on the alternative cart model, EZ-GO.
The cost of each unit should be below $150; effectively cutting the cost by 50%. (3-23-17)
We will worry about trying to lower cost once our prototype is built and ready (we know what needs to be bought, but are there better prices for these materials?)
A Seaflo pump is being considered for the newer units, which cost significantly less than the existing $80 pumps.
Will be in contact with supplier
Instructor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
Different battery configurations should be considered, since some cart models will have 6 batteries of 8 volts each, instead of the 4 12 volt batteries in the cart model available to the team. (3-14-17 meeting with Dr. Silberman and Gravish)
Will talk to Steve Roberts about our circuit design and implementation

N/A
Risks and Areas of Concern
The enclosed tank cannot be refilled without a specific hose and the tank that leaks is not in yet
Related files to the design of the two misting units are held up.
The final system is to be roto-molded, and as such a physical finished product may not be available for the final presentation.
Resources or Information Required but not Available
The bar mounted misting unit does not have the associated molded water tank
One-way refilling hose is needed for further misting head tests
SolidWorks files of the two misting systems have not been received due to logistical reasons.
A Bill of Materials (BOM) is also expected
Schedule
For our next milestone, we hope to CAD and sketch our final design and present it to our sponsor. Also, there are still lingering voltage spike issues, so we need to talk to Steve to fix our electronic issues.
