Week 3 Progress Report
(1/17/2014 – 1/22/2014)
Team 1: Fluorescent Label Simulator
Overview of Status of Analysis, Design, Fabrication, Tests, etc.
Test bed for preliminary prototyping and testing built by 1/17
Photosensors, bandpass filter, and larger LED's to arrive by next week
Microcontroller and Labview software testing in progress
Accomplishments from Previous Week
Dominant wavelength test performed on preliminary test bed prototype
Test bed designs generated and discussed.
Suitable Labview software packages for sponsor's laptop identified
Goals for Next Week (list names after each item). Use specific and measurable objectives.
Testing of preliminary test bed to identify potential risk areas (James, Kyle)
Test bed design process to continue (John, Marina, James, Mike)
Test bed prototype build by 1/31 (John)
Aimed completion of dark room by 1/27 (James)
Continue trialing of DAQ system and creating VI's (Kyle)
Continued research and ordering of density filters, polarizing filters, pinhole apertures, Fresnel lenses, near field diffraction patterns, and appropriate focal lengths (Mike)
Design of pertinent circuits for photosensor-to-DAQ compatibility (Marina, Kyle)
Sponsor Comments from Last Meeting and Actions Taken to Address these Comments
· Comment: Labview software for sponsor needs to be identified. Action: No software is required because UCSD's available Labview package can generate stand-alone executable VI's. The full or professional Labview package is preferred to allow editing of VI's by the sponsor.
· Comment: Project deliverables were approved by sponsor. Action: Deliverables have been noted and included into the final report.
· Comment: Density filter, pinhole filter, and adjustable polarizing filters suggested as options to explore. Action: These filters are in the process of being acquired
· Comment: Temperature stability requirement to identify drift in data after ~20 min of continuous operation Action: No temperature sensors are necessary. Identifying a drift in photosensor log intensity is most important.
· Comment: High accuracy photosensor with single photon detection capability should be included in design. Action: This photosensor has been ordered
Instructor Comments from Last Meeting and Actions Taken to Address these Comments
· Comment: Have sponsors give set deliverables ASAP. Action: Final deliverables have been clarified with sponsor.
Risks and Areas of Concern
Completion of test bed prototype by 1/31. Delay in completion date is acceptable due to schedule buffer; however, the resulting reduction in testing time is unfavorable.
Resources or Information Required but not Available
Photosensor light sensitivity, light saturation, dark current specifications. Vendors only have limited data on specification sheets and communication with vendor is slow and sometimes unreliable.
Schedule
Standalone testing to be completed by 1/29
Test bed prototype to be built by 1/31
Gantt chart updated to reflect delay in LED standalone test and microcontroller standalone test. These tests are still on schedule to be performed prior to arrival of the test-specific photosensors
Budget (list amount spent and amount remaining)
Spent: $557.80
Remaining:$5942.20
