  • Stage found in the lab
  • Has relatively fine

adjustment

  • Need to fabricate base

plate to mount it securely to the isolation table

  • Approached Dr. Lam to discuss speaker dampening
  • Two really important points

○ Added noise in graphs due to lights ■ No way to get rid of that ■ Can implement a filter to reduce the noise ○ We should be wearing earplugs!! ■ Certain frequencies can be damaging to our ears ■ All feasibility testing was done wearing earplugs ■ This was really great advice

  • Ordered Materials
  • Developed designs

○ Redesigned 3 times ○ Discussed with Dr. Lam ○ Suggested a change in the internal pitch angle ○ 3 different fixtures for each ■ Creating one of each first for proof of concept ○ Rob - machining

The Next 3 weeks

Slide 28 11/19/2015 RIT Thermal Analysis Microfluidics and Fuel Cell Lab

For the next three weeks, our team plans to complete the following tasks:

  • Complete fabrication of the speaker enclosure for the large speaker.
  • Complete feasibility testing with PID controls and an oscillating

meniscus.

  • Take appropriate steps to ensure that oscillations aren't damped out

within the system.

  • Follow-up with subject matter experts as appropriate.
  • Demonstrate proof of concept for each subsystem.
  • Develop a detailed test plan for each engineering requirement.
  • Continue purchasing materials as necessary.
  • Continue risk mitigation.
  • Identify areas that we need further help with.
  • Continue baking delicious foods.
  • Purchase bicycles for bike ride.
