156B Week 2

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

• • The design will now include a linear inductance (shaking) power generator rather than cranking or squeezing due to size constraints

  • Emailed and will stay in contact with the organization Arclight that is currently working with solar powered ophthalmoscopes in developing countries

Accomplishments from Previous Week

• • Called an ophthalmoscope manufacturer and obtained a lot of information about the lenses, expenses, and light requirements for the ophthalmoscope head

  • Purchased and tested a squeeze, crank, and shake powered flashlight

  • Used a DMM to acquire information on the voltage generated per shake in the shake powered flashlight

  • Emailed the organization providing eye and ear examinations in developing countries

  • Emailed an optometrist that worked with a device for developing countries

  • Completed individual component analyses for different power generation components, energy storage components, and the ophthalmoscope/otoscope heads

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

• • CAD the handle for our device

  • Purchase components: copper wire, magnet, capacitor, circuit board, ophthalmoscope head, otoscope head

  • Begin constructing our own linear inductor

  • Update website to hit Week 2 deliverables as listed on MAE 156B website

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

• • Updated our sponsor via email about our power generation and design with LED's

  • First meeting of spring quarter rescheduled to week 2

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

• • Need to get financial information sorted out with our sponsor - Emailed our sponsor and they deposited $1500 into an index for our team

  • Email organizations that work on providing eye and ear examinations in third world countries

  • Purchase and test the different power generation devices

  • Perform experiments to determine the amount of power/voltage generated by the different types of mechanical devices

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

• • NA

Risks and Areas of Concern

• • Need to ensure that shaking the inductor will not misalign the lenses in each head

  • Make sure the shake is capable of lighting up 2 LEDs

  • Device must be rugged

Resources or Information Required but not Available

• • Funding problem resolved

Schedule

• • Finalize power generation (We are most likely going with linear induction)

  • CAD the handle

  • Buy ophthalmoscope and otoscope heads

Budget (list amount spent and amount remaining)

• • Spent: $30

  • Remaining: $1470

  • Total: $1500

Progress on Report and Webpage

• • Individual component analyses completed and uploaded to page
