156B Week 10
Overview of Status of Analysis, Design, Fabrication, Tests, etc.
Achieved 2nd place in E-Challenge finals on 5/29/15
Machine is almost finished: potential changes to be made are entirely optional
Stepper motor addition to solids dispensers
Machine currently being cleaned and prepared for final delivery to sponsors
Accomplishments from Previous Week
Greatly refined Chai taste
Multiple meetings with sponsors since last project management post
Worked together to fine-tune the process so that a more authentic taste is achieved
More tea and masala
Longer boiling time after milk is added to increase cream flavor
Supported sponsor presentation at E-Challenge finals
Created and installed side panels onto machine for greater aesthetic appeal
Installed more powerful pump
Faster fluids dispensing rate
More effective flushing
Installed a "solids slide" of bent sheet metal to facilitate insertion of solids through the funnel
Goals for Next Week (list names after each item). Use specific and measurable objectives.
Finish final deliverables:
Report
Poster
Webpage
Entirely wrap up the machine and deliver to sponsor
Instruct the sponsors on proper operation, handling, and cleaning
Present project at poster presentation

Comments made through e-mail on 5/31/15:
Meeting schedule with interested parties:
Monday June 1: 5:30 PM
Tuesday June 2: 5:30 PM
Thursday June 4: Tentative
Add stepper motor for solids dispensing
Adjust cooktop and stirrer code so that even greater consistency can be achieved (sans frothing)
Organize tea tasting sessions at Rady and MAE
Actions taken:
The group is prepared for the meetings
Stepper motors have been ordered and will be implemented upon arrival
Cooktop and stirrer code to be refined throughout the week
Instructor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
Comments made in-person on 5/23 presentation:
Obtain taste surveys from sponsors
Implement cursory surveys through presentation feedback from class
Actions taken:
Requested surveys from sponsors but have yet to receive them
Comments from Other Students in the Class (indicate date of comments and if via email or in person)
Comments made in-person on 5/23 presentation:
Use stepper motors to better quantify solids dispensed
Possibility of chiming a bell when tea is finished
Chai needs a stronger flavor
Find a way to cover the machine
If printing out any more acrylic sheets, use bright colors
Actions taken:
Stepper motors have been ordered
Chiming a bell would be novel but not a major concern: moreover we have run out of Arduino ports
Flavor has been fixed:
Significantly more tea and a bit more spices are being added to each brew now
Cover has been made using yellow-colored acrylic
Risks and Areas of Concern
Timeline for planning taste testing and passing out surveys
Only a couple days left until finals week
Stepper motor will be difficult to integrate with the preexisting hardware
Mounting solutions
Code troubleshooting
Random catastrophic failure of the machine
Resources or Information Required but not Available
N/A
Schedule
Meeting with various interested parties throughout the week
Arranged by sponsors
Begin shifting focus from hardware to report, webpage, and poster
Finish cleaning machine to prepare for final delivery to sponsor
Implement any last-minute changes required
Budget (list amount spent and amount remaining)
Spent: $1007.30
Remaining: $-7.30
