156B Week 2

Overview of Status of Analysis, Design, Fabrication, Tests, etc.

• • Lenses have been designed and can be printed with different etchings; ready for testing (photoresistor is ready) 

  • Temple frames have been designed and need to be checked to see if circuitboard can fit while maintaining aesthetics

  • CAD designs for tree stress wave housing have been finalized and primary designs have been conceived; minor alterations may be needed for operating purposes 

Accomplishments from Previous Week

• • Further refined our tasks and work breakdown structure; we realized that task groups for individual projects are more useful and productive than doing both projects simultaneously. 

  • CAD designs for both tree stress and jet lag 

  • Testing phase begins 

Goals for Next Week (list names after each item). Use specific and measurable objectives.

• • Testing for both projects (Chris and Khoa) 

    • Forces need to be measured for tree stress 

    • Lens' photoconductivity for jet lag (Chris and Brian)

• Temple Frames (Arthur)

• Housing (Brenda)

Sponsor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)

• • Tree Stress sponsor was receptive to our Risk Reduction presentation and wants to address operation manual and instructions for production purposes. (156A Finals week) 

    • Arranging meetings to demonstrate completed housing 

Instructor Comments from Last Meeting and Actions Taken to Address these Comments  (indicate date of comments and if via email or in person)

• • Instructors approved of Risk Reduction charts and WBS, now the team needs to dive into specified goals for both projects.

Comments from Other Students in the Class (indicate date of comments and if via email or in person)

• • From the Risk Reduction Presentation, certain housing elements such as protrusion of base plate appeared to be obstructing the housing and making it even more inefficient.  

Risks and Areas of Concern

• • Snapping mechanism for the housing may not be as secure as we'd like 

  • Power transfer between frames of glasses 

Resources or Information Required but not Available

• • Force Gauge to measure forces on hammer strike

Schedule

• • Begin Testing throughout Week 3 and hope to finalize design after that 

Budget (list amount spent and amount remaining)

• • $10 spent for Jet Lag Glasses

  • $0 spent on Tree Stress 

Progress on Report and Webpage

• • Report has been started and Webpage has been updated
