156B Week 8

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

• • Changed camera again

    • testing in progress

  • More ideas/prototyping for physical design

    • cases designs

      • dovetail mount****

    • hat prototype

Accomplishments from Previous Week

• • Camera testing:

    • ambient temperature effects determined!

    • background effects still unknown

    • changed the python script

  • Case/mount

    • prototyping go-pro case -- still needs updating

    • dovetail design -- needs to be 3d printed

  • hat prototype testing

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

• • finish camera testing

  • print and test dovetail design

    • make design modifications

  • Finish wiring camera

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

• • Change plots from scatter plots to box and whiskers

  • Change method of data acquisition

    • currently each second is its own data point

    • suggestion: change so that 10 seconds get averaged to one point. Then get several points

  • likes dovetail design

    • modification suggestions -- from side to further back on case

  • potential for microcontroller without raspberry pi

  • verification -- digital glasses aren't really our concern

  • No plans to have this mass produced. Just for research use at UCSD and UCSD hospital

  • camera might be affected by humidity

    • for reference on the report, air particles emit BB radiation. That's why larger distances are less accurate

      • more particles in between messing up our measurements

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

• • Likes dovetail design/universal mount

Comments from Other Students in the Class (indicate date of comments and if via email or in person)

• • looping wire under shirt?

  • Glasses? how does that play into our project

Risks and Areas of Concern

• • Time!!!! Will we be able to put everything together in time?

  • Case/mount strength

Budget (list amount spent and amount remaining)

• • Used this week: $139.55

  • Used total: $439.44

  • Remaining: $570.56
