156B Week 6

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

• • Power generation components have been purchased and validated

  • Solenoid will be manufactured in machine shop

  • Entire circuit with LED's will be built this week

Accomplishments from Previous Week

• • All major electrical components purchased

  • Ergonomic handle CAD'd and 3D-Printed; Received positive feedback from sponsor

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

• • Edit handle CAD using sponsor feedback - Ariyan

  • Construct Solenoid in machine shop; Test with purchased magnets - Chris/Charmaine

  • Construct circuit (using a breadboard) with power generation, capacitor, and LED's attached - Chris/Andrew/Charmaine

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

• • From in-person meeting on (5/2/18):

    • Handle does not need as many curves as it currently has. More geometric, cut-edges would be better

    • Length of handle cannot be too long or "it will look like a staff"

    • Actions taken: CAD of handle edited, components that were purchased (capacitor, switch) need to be small enough for size requirement

  • Time it takes to charge (from our calculations) is good

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 measure the power output when a load is applied to the power generation device (from meeting on 4/30/18)

    • Actions taken: Experiment was set up using an oscilloscope to validate the power generation of the device and 

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

• • N/A

Risks and Areas of Concern

• • The structure of the handle must be small but still fit all power generation and circuit components

  • The handle must withstand vigorous shaking

  • The heads must be precisely CAD'd to ensure lenses will fit properly

Resources or Information Required but not Available
