This past week, we worked hard on writing the remaining pieces of the design report, revising, and adding in figures. I spent a lot of time figuring out how to access the I2C ports on the Jetson. Unlike Adafruit, NVIDIA doesn\u2019t provide a friendly little tutorial to hold your hand through the process \ud83d\ude41 but I figured out what packages to install and what modules to import, so now I can get I2C input from the mics. My analog microphones and ADC arrived sooner than anticipated, so I didn\u2019t bother trying to work with the two-microphone I2S setup and just dove into the I2C setup. However, this past week was absolutely wack for me, so I didn\u2019t achieve the goal I set last week to get the algorithm working. I did, however, write the pseudocode, so the primary hurdle will be using what I learned about I2C on the Jetson in my actual code. I also tested the range of our new microphones (which we\u2019ve been a little concerned about), and they seem adequate for our expectations.<\/span><\/p>\n

In addition, I realized that, in our mechanical design, we have the microphones on the side of the base, but that wouldn\u2019t work for audio detection because the mics would only be able to catch the audio on that side of the device. We originally wanted to put the microphones on the top of the base but later moved them to the side, in order to distance them from our noisy motors, which remain a problem. I\u2019m wondering if it would be possible to have one mic on each of the three sides of the base (one of the sides is open and is where we\u2019ve inserted the Jetson)\u2026 I\u2019m just worried that that would capture sound differently than anticipated in our design.<\/span><\/p>\n

For this week, I\u2019ll experiment not just with the arrangement of the mics, but also the orientation of each microphone to see how that changes sound detection. I will also work on writing the acoustic location code.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
