156B Week 7

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

• • Currently beginning fabrication of enclosure and adapter(s)

  • Continuing some modified configuration tests to determine some preliminary design aspects

    • Adding components to dampen vibrations, reducing heater distance/changing orientation, etc.

Accomplishments from Previous Week

• • Configuration testing resulted in temperature variation of <1 degree Celsius

    • Proof of concept validated

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

• • Progress on fabricated parts

  • Consensus on key design features from testing

    • Agree to a presentable preliminary design

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

• • Take care to reduce vibrations caused by the fan heaters as it will affect image quality

    • Conducting an in-lab imaging test on Wednesday meeting with sponsor

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

• • Elaborate on the background of the project

  • Explain testing configurations and the progression into other configurations

  • Think about using hollow thread rods for aspects that are difficult to machine

  • Use a comparison table to summarize test findings

    • General action(s) for comments: Will be taken into consideration if applicable in next presentation

      • Will see if hollow thread rods can be substituted into design

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

• • Could a circulation method be incorporated?

  • Try pressfitting the circular components

  • Improve legibility of powerpoint

  • Elaborate on background of experiments

  • Adding a video may help in explanation

  • It may be good to consult an engineer for the PID control later on

  • Explain the general design of the project more

Risks and Areas of Concern

• • Vibrations caused be the fan heaters

  • Stabilization of PID controller with changing configurations

Resources or Information Required but not Available

• • How to replicate/deal with issue of sample holders

Schedule

• • Finalize preliminary design specifications

  • Fabricate enclosure and adapter(s)

  • Check for/order any remaining parts that are missing

Budget (list amount spent and amount remaining)

• • Amount Spent:

  • To date: ~$600

  • Amount Remaining:

    • Highest Possible (assuming $5000 reserve): $4400

    • Lowest Possible (assuming $3000 reserve): $2400

Progress on Report and Webpage

• • Working on Second Draft of Report (Due Friday 5/18/18)

  • Working on Second Draft of Team Webpage (Due Friday 5/18/18)
