Overview of Status of Analysis, Design, Fabrication, Tests, etc.
Hoping to achieve a working prototype by this Thursday for a sponsor meeting
Accomplishments from Previous Week
Tested valve, confirmed that we could pump out (Alec)
Ultrasonic sensor testing (Phil)
Ordered additional parts (Phil & Alec)
Report (all)
Assembled 8020
tab-screw mechanism validation
Goals for Next Week (list names after each item). Use specific and measurable objectives.
finish modules, mount modules unto frame
Validate (and improve) tab-screw mechanism (printing material, watertight coating)
Update electrical schematic AND process schematic
Control pumps with Arduino/PWM
Get acrylic / cut out for mounting
Hole in kettle
Order amp for temp sensor
Print parts
Get power supply plugged in and working
Prototype mesh filter
Start looking at displays / user interfaces
Sponsor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
Peristaltic pump not necessarily off the table, depends on prototype
Get new bolts at hardware store
Don’t need to buy special 3DP plastic if we’re coating it anyway (only issue is dimension change)
Pump: figure out PWM through motor driver
Go with thermocouple for now
Instructor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
RTD vs. thermocouple
Variable PWM for pump
Seats and seals for valve (stainless steel)
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
