156B Week 5

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

• • 1st handle design 3D printed

  • CAD of otoscope drawn

  • Design justifications need to be validated

Accomplishments from Previous Week

• • Handle designed and printed

  • Supercapacitor chosen

  • Created working model of power generation with springs

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

• • Validate design theory

  • Build circuit for proof of concept

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

• • Determine theoretical vs experimental of voltage output from each shake

  • Measure voltage using oscilloscope or Arduino

  • Talk to Tom Chalfant about electronics of project

  • Steady testing from movement

    • Simulate with working model

    • Restricted by length of 2 batteries

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

• • None

Risks and Areas of Concern

• • Need to ensure that tests will validate theory used

  • Ensure whole design will be small enough to be implemented

Resources or Information Required but not Available

• • None

Schedule

• • Record voltage generated by linear inductor

  • Validate and justify design of linear inductor

  • Build and test full circuit with linear inductor, supercapacitor, and leds

Budget (list amount spent and amount remaining)

• • Budget: $1500

  • Spent: $204.47

  • Total remaining $1,295.53
