Team Status Report 4/12
What are the most significant risks that could jeopardize the success of the project? How are these risks being managed? What contingency plans are ready?
The most significant risk at this stage of our project is ensuring that we have enough time remaining for integration. To mitigate this, we’re integrating components as they’re developed, rather than waiting until all parts are complete. In addition, we’re thoroughly testing each component during development, since the time we have for final project testing may be limited. This helps us catch potential issues early and reduces the risk of running into issues during the integration phase.
Were any changes made to the existing design of the system (requirements, block diagram, system spec, etc)? Why was this change necessary, what costs does the change incur, and how will these costs be mitigated going forward?
No changes have been made to our block diagram in the past two weeks.
Now that you have some portions of your project built, and entering into the verification and validation phase of your project, provide a comprehensive update on what tests you have run or are planning to run. In particular, how will you analyze the anticipated measured results to verify your contribution to the project meets the engineering design requirements or the use case requirements?
To test our end-to-end integrated system, we plan on using event logs at each stage of our system to measure the latency and ensure it meets our design requirements. We plan to closely monitor the synchronization between audio and lyrics, ensuring that the delay is small enough as to not impact the user experience. In addition to system integration testing, we plan to each thoroughly test our components as described in our individual status reports.

What did you personally accomplish this week on the project? Give files or photos that demonstrate your progress. Prove to the reader that you put sufficient effort into the project over the course of the week.
This week, I worked on cleaning up some of our UI including pulling, displaying playlists, lyric display, and miscellaneous CSS. I also used some sample data to simulate output from Hugo and Kiera’s scoring algorithms to allow for
Is your progress on schedule or behind? If you are behind, what actions will be taken to catch up to the project schedule?
My progress is on track. However, it will be a push to integrate the components of my group members works into my application.
What deliverables do you hope to complete in the next week?
As above, I will integrate Hugo and Kiera’s components into the web application. Additionally, I will deploy the web application so it’s accessible by URL (or at least port) instead of needed to be locally deployed.
Kiera’s Status Report 4/12

This week, I worked primarily on writing a python script to use the motion data, sent from the Arduino via Bluetooth, to detect significant changes in motion and match the timing of the change to the beat of the song. To determine timestamps of the beat, I retrieved the BPM of the selected song from the https://getsongbpm.com/api. Once the start function is triggered, timestamps for each beat are generated at intervals based on the song’s BPM. These are compared to the timestamps sent along with our accelerometer data to determine how accurately the user is moving along to the beat.
In addition to beat tracking, I worked on capturing a signal from the microphone to the Arduino, but the mic output wasn’t strong enough for the Arduino to detect. Instead of building an amplifier for the current system, I decided to order an Arduino breakout microphone component with a built-in amplifier.
Is your progress on schedule or behind? If you are behind, what actions will be taken to catch up to the project schedule?
My progress is still behind schedule because of the delay from ordering the new microphone component but I’ve been working on other aspects of the project to catch up to schedule.
What deliverables do you hope to complete in the next week?
By next week I hope to have a fully working microphone prototype and a microphone casing designed in SolidWorks.
Now that you have some portions of your project built, and entering into the verification and validation phase of your project, provide a comprehensive update on what tests you have run or are planning to run. In particular, how will you analyze the anticipated measured results to verify your contribution to the project meets the engineering design requirements or the use case requirements?
To verify the change of direction detection algorithm, I move the Arduino through a series of distinct motions and check that the detection timings align with my movements. For testing the beat tracking algorithm, I run the system twice: first moving the Arduino in time with the beat as accurately as possible, then moving it randomly. I compare the resulting scores to confirm that following the beat results in a higher score. Our use case requirements don’t prioritize scoring precision, since it is intended to be a fun feature rather than an actual metric for improvement.
Hugo Status Report 4/12
Over the last two weeks I have had a lot of good progress with regards to finalizing our hardware. After all of the parts arrived last week, I was able to build the first full prototype of the filter and had a lot of issues with it. The sound quality was very poor, with mostly crackling and static at the speaker output. I looked into what issues could cause this, and decided that the most important part to fix were the loose connections. Because I am using a breadboard for prototyping, I did not have the ideal protoboard pin connections to hook up the input jacks that I ordered, and so I had originillay just tried to essentially tie on the wires, but these connections were extremely poor and I feel that was a large reason for the struggle. However, I have now soldered on the wires and made firm connections which hopefully will create a big boost in performance.
Additionally, I realized another obvious issue was that I was building my setup with a single 9V battery with a +Vdd and ground. This is an issue because the opamps require +Vdd and -Vdd, and so obviously this was leading to cutoffs with my audio output. I am now looking into two possible solutions, either using two batteries with the intersection as ground, or creating a virtual ground and splitting the 9V. I am currently leaning towards the former and am hoping to test it out this week. Additionally, I have started building the circuitry for connecting the microphone input into the circuit. There is some worries about how well the ESP32 bluetooth part we are using will work but I have found some examples online about how to use it to build systems like bluetooth speakers and so I am feeling better about the forecast for that.
That will be the first major part of implementation for my work, as the vocal removal is already connected to our webapp.
