Team Status Report for March 6

This past week, our team finished up our design review presentation; we also went over the feedback from the project proposal presentation and incorporated it into our project. Cambrea set up the respeaker and created a set of test audio data. Ellen tested the ML software on the test data and eliminated one of the ML options that we considered, and investigated the other option that Abha, our TA, suggested. Mitchell continued working on the website.

Some parts of our schedule have been shuffled around earlier as we got our hardware earlier than expected, but according to our modified schedule, we are still on schedule. We did encounter a risk this week. We spent a time chasing models that are duds and we eliminated it by testing early and finding alternatives. One of the models had a 100% error rate. Design change wise, we also are adding a LED indicator when audio is not being picked up and audio preprocessing for the ML. Next week, we will be finishing up our design report and continue our first phase.

Mitchell’s Status Report for Feb. 27

This week I setup the server and worked on the design slides outline and design document. I first attempted to deploy the server on Amazon Linux 2, but encountered difficulties after recompiling python for a newer sqlite, so I redeployed the server on ubuntu 18.04. The server is currently in a condition that it can be run, but is empty. We also decided that we wanted to create a custom fitting for our device, so I looked into three options based off of previous projects: woodworking, laser cutting, or 3d printing one. After looking into it, I directly eliminated woodworking as it would be time consuming and requires more manual dexterity. Laser cutting and 3d printing would require CAD work. Laser cutting would allow reuse of old iterations as do not have to scrap the entire housing, while 3d printing would require printing the whole object if iterating. I think that using a mix should work for our project

I filled out the design slides outline and design paper generally, so that the information is there and can refine next week.

In terms of progress, I believe that I’m on schedule. Next week I’ll start testing scipi and audacity for the audio filtering, and continue working on the design document and presentation.

 

 

Mitchell’s Status Report for Feb. 20

This week my efforts were focused on research and slide preparation. On the research end, I looked into audio filtering methods, aws setup, and methods of testing. I looked into the ReSpeaker, PyAudio, Audacity, and SciPi libraries for methods of audio processing and to see what we could leverage. I also looked for research papers for processing the audio, microphone feedback, and user design. I also looked into methods of testing like stress testing to make our system more robust.

I believe that I am currently on schedule. Our project proposal slides are complete and our initial gantt chart has been created.

From our gantt chart, I will be starting to setup the AWS server and website next week as well as starting to prepare the design presentation.
