156B Week 6

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

• • 9 coil array constructed, testing has begun, it is not as functional as we hoped

  • Metal for magnetic cores and plates has arrived

  • Many other things ordered, ready to be assembled

Accomplishments from Previous Week

• • 9 coil array constructed

• • CAD model of the final product created

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

• • Magnetic plates and cores machined and attached to the coils. - Edward, Jordan

  • CAD models updated, case 3D printed. - Siddarth, Edward

  • Specifics of coil dimensions and analysis completed. - Nick

  • Report work completed. - Chris

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

In Person - 5/3/2017

• • Showed 9 coil array, said that we may want to spread apart the coils - Going to look into the right spacing of the coils

  • Should look like "an iPad", be very very thin - Continuing to optimize design for thickness

  • Would look impressive if the case was made out of metal - Asked Ian about making the case out of metal

  • Sponsor would now like the total height of everything to be under 5mm

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

In Person - 5/1/2017

• • Ian said that making a case out of thin aluminum would be very difficult and time consuming - Looking into 3D printing, but designing it such that it may be made out of metal easily later

  • Prof. T was worried about finding a way to stir larger beakers using the 4 stirring position model. - Plan for later on, if our 4 stirring position design is successful. Don't need to worry about it for now

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

In Person - 5/1/2017

• • Will batteries fit within the dimensions? - Yes, we will make it work out. Thickness is a bigger priority than the other dimensions, and thin batteries definitely exist.

Risks and Areas of Concern

• • The specific dimensions of the coils, the spacings, and the optimal current are still being figured out. No single equation works well to find it all.

  • The magnetic cores and plates still need to be machined correctly

Resources or Information Required but not Available

• • None

Schedule

• • Working 9 coil array by the end of the week, including magnetic plates and cores

  • Update Gantt chart.

Budget (list amount spent and amount remaining)

• • Spent: $1081.54

  • Remaining: $3918.46

Progress on Report and Webpage

• • Report being continuously worked on, filling in spots for final design decisions

  • Weekly team meeting notes on drive uploaded under Files tab.
