156A Week 10

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

• • Finished brainstorming key plunger mechanism for separating coffee grinds and coffee

Accomplishments from Previous Week

• • Thoroughly explored three ideas for the plunging mechanism

  • Performed coffee brewing experiments to validate plunging mechanisms

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

• • Finalize plunger design choices (all members)

  • Order parts (all members)

  • Fabricate proof-of-concept builds for chosen designs (all members)

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

• • All comments made in person on Monday 12/3

    • Automatic cleaning is not required

    • Pump Design

      • Make sure pump is fast enough, care from splashing, ensure mixing of coffee

      • Explore different ways to remove beans. Could we automate it?

    • Linear motion methods look like cool solutions, but a lot of moving parts

    • Really want ground beans, even if it means just buying a grinder and taking it apart

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

• • All comments made in person on Tuesday 11/27

    • Focus on plunging method for the rest of the quarter, figure out rest of system later

      • Come up with designs for both extremes: completely automated vs completely human

      • Make at least 2-3 drawings

    • Electrical system is not the biggest safety concern, hot water is

    • Order Parts

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

• • Plunging Mechanism

  • Water Temperature Control

  • Grind Size Control

Resources or Information Required but not Available

• • Still looking for the right parts to use which depend on the design we solidify

Schedule

• • Build Brewing module prototype

  • Gantt chart updated

Budget (list amount spent and amount remaining)

• • Burr Grinder from Amazon $32

Progress on Report and Webpage

• • Gained understanding on how to navigate and what to edit/add to webpage

  • Added team info
