156B Week 8

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

• • Heating

    • both heating pads have been wired up

    • will be using insulation foam so that brewing container makes proper contact with heating pads

    • attaching heating pads to insulation 

  • Gate Valve

    • 3D printed arm attached to solenoid to depress spring loaded valve

  • Stirring

    • teflon coated magnetic bar used to stir milk 

    • motor with magnets attached to it will spin to turn the stirring stick

Accomplishments from Previous Week

• • Heating

    • was able to obtain heating pads and wire them together 

      • tested the heating on the container/measured temperatures with water

        • is able to keep water warm

  • Gate Valve

    • different shapes of arms 3D printed

    • trying solenoid and stepper motor to see which one can work better for our application

  • Insulation

    • recently bought, need to test it to see if it'll work as expected

  • Stirring

    • everything else done, just need to attach raised base and test for tipping

  • Controls

    • met up with both their electrical engineers and was able to go over necessary objectives and test relays

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

• • Integration

    • attaching new base that complies with tipping standards (IAN)

    • attaching solenoid/stepper motor to 3D printed arm and test with water (ARUN)

    • integrating heating pads with insulation and testing whether proper contact is made with brewing container (SOO)

Progress on Report and Webpage

• • Notes from 1st draft taken into account and edited

    • need to add parts on the 3D printed arm, insulation, etc

  • Webpage

    • multimedia has been added

    • prototype pictures have been added

    • need to
