156B Week 2

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

• • Two main designs will be tested out now

    • using a stiffer materials than a straw (ie, glass rod) to smear

      • based on last previous teams design

    • using a premade disposable smearer

      • dispose of smearing device after each sample

  • Goal is to get both of these tested and CADed this week 

Accomplishments from Previous Week

• • eliminated the tape method

    • patented design 

  • completed trainings required for lab saftey- cindy

  • set-up beaglebone and LCD screen - Marco

  • list of new possible methods for smearing

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

• ALL

  • Presentation- due wednesday night

    • Report- due friday night

    • Add final report

• Kevin

  • Blood smears with pig blood

  • Design for rod smearing

  • Linear guide- source

• Marco

  • Order op-amps and resistors

  • Force sensor tests and codes

  • Beaglebone setup

  • Cindy

  • Order disposable parts (do they have patents?)

    • Lab coats for everyone

    • Update meeting notes on webpage

    • Design for disposable perfect smear thing

• Christopher

  • • Automated blood dispensing

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

• Design Idea 1: Tape for smearing

  • Using just the tape (maybe a stiffer one) to guide the blood to smear

  • Wicking instead of smearing (no patent infringment)

    • Verify vs validation

    • Because of this, disposables are much easier and don’t need to “prove” cleanliness

    • Nonadhesive tapes give the thinnest layer of blood

• Design Idea 2: Glass rods

  • Geometry issues

  • Need to figure out the best cleaning method/liquid

  • we could potentially use disposable rods and eliminate the need to verify and validate cleanliness 

  • ***no liquids. All disposable stuff

• Electronics

  • • Prefer simple bootup as opposed to desktop screen

    • Eventually want a wifi module to review images remotely 

• Best design

  • plastic rod and dispose of it after every smear- sponsor

  • Most guaranteed way of decent smear
