Overview of Status of Analysis, Design, Fabrication, Tests, etc.
Begun data collection in the frontyard sprinkler system.
Halfway through test bed construction. Require poly-carbonate pieces, additional 80/20 nuts and bolts (to attach polycarbonate to aluminum extrusions), water pump (sponsors are providing).
Piping configuration for the testbed is glued (rise valve requires assembly).
Preliminary tests on testbed completed.
Accomplishments from Previous Week
Sam purchased drill bit to help machine a part for the pressure sensor.
Purchased water proofing materials for testbed.
Front yard data trials begun.
Goals for Next Week (list names after each item). Use specific and measurable objectives.
Drill holes in testbed for water drainage (Sam and Madeline)
3D print new case for accelerometer (Madeline)
Varnish (waterproof) the testbed (Sam)
Purchase polycarbonate (Bryan)
Machine part for the pressure sensor (Sam) Ensure that pressure sensor works for data collection (Gordon and Bryan)
Improve team website (Gordon)
Perform experiments on testbed and correlate amount of air in pipe with the phase difference of the accelerometer signal (All)
Sponsor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
Find a way to correlate the amount of water out with the time difference between the first and second spike in the data and test the theory above (aka the phase difference).
Investigate different statistical methods to establish thresholds of different scenarios (moving average, standard deviation, negative area, root mean square)
Instructor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
More figures with clearer labels and dimensions.
More figures for pre-existing solutions
Make conclusions based on more data
Risks and Areas of Concern
Electronics used for testing and data collection being damaged by water
Resources or Information Required but not Available
Schedule
Upcoming: Drill holes in testbed for drainage and varnish the surface. Perform more experiments on testbed.
Budget (list amount spent and amount remaining)
$16 at Big Lots for storage container to be used as water reservoir.
$123.08 spent at Home Depot for varnish + accessories and pipe accessories.
