156B Week 2

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

• • Items were ordered to continue development, we're waiting on a lot of stuff

    • Wires, so we can try different size wires

    • Raspberry Pi, so we can control the stirrer

    • Iron, so we can make cores and plates

  • Extra coils were printed

Accomplishments from Previous Week

• • Ordered many items from online vendors.

  • Completed Individual analysis

  • Completed Design Proposal Presentation

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

• • Complete segments of the final report. - Everyone

  • Do basic Raspberry Pi code, to control coils. - Jordan

  • CAD model of stirrer. - Siddarth

  • Make iron cores. - Edward and Nick

  • Make new coils. - Christopher and Siddarth

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

5 April 2017 - In person

• • Suggested looking into cooling materials to disperse heat from the coils.

    • Still need to see if this is necessary after using bigger wires. Bigger wires may reduce the heat enough that cooling materials are not required.

    • Using fans is impossible due to size and sealing requirements.

  • Can calculate temperature of coils by measuring current in them and voltage across them.

    • Will look into doing this

  • Gold wire wouldn't really gain us anything other than expense.

    • Right, silver wire would be slightly better than copper, but probably wouldn't be worth it. Copper is good enough.

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

• • None

Risks and Areas of Concern

• • Making the iron plates is still an area of concern, we don't quite know how to do it, but we'll make it work.

  • Making the Rapberry Pi fit into the size requirements is still a big question.

Resources or Information Required but not Available

• • None.

Schedule

• • Start final report by Friday.

  • Get coils working under Raspberry Pi control by this weekend.

  • Update Gantt chart.

Budget (list amount spent and amount remaining)

• • Spent: $148.38

  • Remaining: $4851.62

Progress on Report and Webpage

• • Getting started this week.
