Overview of Status of Analysis, Design, Fabrication, Tests, etc.
Graphs and data produced by Tim consistently show that device is feasible (within +/- 5% without calibration).
Fieldscout probe seems to provide wildly inconsistent readings.
Accomplishments from Previous Week
Started design of insertion probe with ESI sensor integration. (Evan)
Obtained second bucket of biosolids (Armando)
Performed gravimetric method of second sample of biosolids and confirm moisture content green waste compost after oven was unplugged during the weekend. (Tim and Paulie)
Goals for Next Week (list names after each item). Use specific and measurable objectives.
(Evan) Finish probe design and manufacture prototype in aluminum in the machine shop.
(Team) Test feasibility of working prototype onsite.
(Armando) machine the handle for insertion probe
(Paulie) Organize the report for a presentable first draft.
Sponsor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
18 January 2016:
Design Proposal: "Invasive" approach (leaving probe in to settle between scarab turnings) or "semi-instantaneous" approach
Conference call with Mary (owner of compost facility) regarding leaving probe in piles; she confirmed, not an issue
Instructor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
26 January 2016 meeting in EBU II:
Include the application of standards (OSHA, hard hats, vests, ect.). Data needs to be more consistent around the same spot on the pile, verify using the gravimetric method.
From Mary, Owner Agronomist on 22 January 2016:
Consider the amount of time that has elapsed since a pile has been turned; observe variation, if any, in probe readings.
Possibly schedule a meeting with Nathan O'Connor to discuss applicability and usage.
Comments from Other Students in the Class (indicate date of comments and if via email or in person)
No comments.
Risks and Areas of Concern
Detection method: Insertion or semipermanent.
Resources or Information Required but not Available
Still waiting on the 4 foot ESI probe to arrive to reotemp.
Schedule
The upcoming milestone: Get new probe from Nathan. Same technology as ESI probe, except there are 8 sensors divided by diodes. Testing will include readings of the 8 sensors (individually) and an average. Ram rod design will need to be developed in order to gather empirical data over the weekend and/or on Friday.
Manufacture prototype.
Update Gantt chart.
Budget (list amount spent and amount remaining)
No student purchases have been made since last meeting.
Spent: $1479.93
Remaining: $4520.07
Progress on Report and Webpage
First draft of the report to be completed by Friday and additional information and progress posted to the website.
