Sponsor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
Meeting on 5/17/2019 in Lab Space to show current design
Impressed with team's progress
Further stressed user interface importance
Team is looking into incorporating GUI on LCD
Questions about safety protocol and procedures to have lab techs test our device
Team is seeking approval or certifications for device
Meeting on 5/20/2019 in CALM Lab to view Hematek
we brought frame to the lab for sizing measurements
Need to increase length slightly to fit around Hematek
Team has ordered longer t-slots to arrive this week
Sponsor suggested we make the LCD angle adjustable
Team will add this to our stretch goals
Instructor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
Meeting on 5/17/2019 in Lab Space
Need to take human factors more into consideration (electrical, interface, maintenance)
Team is beginning to incorporate GUI, PCB, Cleaning manual
expresspcb
easypcb
ask other teams for GUI and PCB help
material compatibility with common lab cleaning products, IPA and bleach (how often do parts need to be replaced)
Use mosfet transistor for fan
using this now
Ask other for help
For wire routing
Use SolidWorks features
80-20 routing solutions
caterpillar or festoon for servo cable management
Comments from Other Students in the Class (indicate date of comments and if via email or in person)
NA
Risks and Areas of Concern
Making as many features as adjustable as possible (design for manufacturing)
making angles, heights, smear, code adjustable
Resources or Information Required but not Available
Steps to have device inspected and approved for basic testing with human blood?
