Skin Color Monitor Progress Report # 11, November 22, 2007 Client: Prof. John Webster Team: Jack Ho (Leader) Patrick Kurkiewicz (Communications) Joseph Yeun (BWIG) Brian Ginter (BSAC) November 16 to November 22, 2007 Problem Statement Develop a miniature electronic device that records change in skin color during hot flashes. Last Weeks Goals • Continue testing o Different LED’s o Different Phototransistors • Wait for materials Summary of Accomplishments With another short week, we (except for Joseph, who left on Tuesday for break) managed to get together on Tuesday to get testing done on our device. We managed to get good readings when testing on solid surfaces, however when we ran tests on skin, we weren’t able to get solid readings due to the current material being too soft and deformable. The output voltage varied too much depending on how much pressure was being applied to the skin. We’re hoping, however, to receive our acrylic and polycarbonate materials on Monday, so that we can create a new case out of these more rigid materials, which we believe will alleviate this problem. Noting the deadlines, we also discussed the things that needed to be done and things we would like to be done, and set up a meeting with Webster on Monday to discuss these things as well. Other topics included how to keep the skin to be tested immobilized when the device was worn, getting a chip ordered and getting a battery as a voltage source, and attachment of the device. This coming week we plan to be in the shop and fabricating devices as soon as we get our materials. This Weeks Goals • Fabricate devices • Look into getting a chip printed and getting a battery connection. • Meet with clientActivities Jack: Team meeting (1.5 hrs) Work on design (2.0 hrs) Total: 3.5 hrs Brian: Team meeting (1.5 hrs) Work on design (2.0 hrs) Total: 3.5 hrs Patrick: Team meeting (1.0 hrs) Work on design (2.0 hrs) Communication (0.5 hrs) Total: 3.5 hrs Joseph: Team meeting (via email/phone) (0.25 hrs) Total: 0.25 hrs Project Schedule 9/7 Form team, contact client, assign team roles, set up client meeting 9/14 Literature search, create problem statement, begin PDS 9/21 PDS, brainstorming, begin developing designs 9/28 Brainstorming 10/5 Decide on 3 design alternatives, prepare for mid-semester presentation 10/12 Work on presentation 10/19 Mid-Semester Presentation 10/25 Hand in report (and PDS) and notebooks, decide on final design 11/2 Work on final design 11/9 Work on final design 11/16 Work on final design 11/23 Thanksgiving Break 11/30 Work on final design, poster presentation and paper 12/7 Final Poster Presentation 12/12 Hand in final written report and notebooks 12/14 Final meeting with advisors Expense Date Place Purchased Price 9/17/07 ECE parts shop LED’s, breadboard, wires $9.82 9/21/07 UW Bursar’s Office Keycards $50
