● 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 2811/19/2015 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.
