Note: Our team has compressed our images and videos, but the media upload quota is still full, so this report does not have photos that we would have liked to attach. A lot has gone on over the past two weeks. I created a frame for mounting the battery, Read more…

Note: Our team has compressed our images, but the image upload quota is still full, so this report does not have photos that we would have liked to attach. This week, I made adjustments to the servo mounting, and added in holes to accomodate the heatset inserts to the lid Read more…
This week, I adjusted the inserts of the main Visor body to fit the basket more flush. I also condensed the sensor cavity because the top opening just needed to accomodate the mounted sensors. Because the sensor cavity combined with the main body was too big for the printer Read more…
This past week, I worked on designing, modeling, and constructing the air dam prototypes. The designing took a bit of time because while we were adapting an existing 3d model for the rack and pinion system, we needed to keep a few things in mind. The servos have a maximum Read more…
This week, I finished a second iteration of the Visor’s sensor cavity and main body 3D models. For the sensor cavity, I included the outer casing for the intake, expanded the size to accomodate the sensors since the first iteration was too small, and started working on creating lids. For Read more…
This week, we did a bit of testing with the constructed prototypes. The printed sensor box is a bit too small to house the sensors in the way we want it to, but we should be able to get a lot of mileage out of this prototype for testing. I Read more…
This week, our parts arrived and we were able to continue to make progress on the hardware side of our project. Our team met with both Sofiya Filippova, who worked on a project similar to ours during her time at BU, and Professor Michael Taylor, whose thesis was on low cost air Read more…
This week, I helped with working with the API for the ACHD database of air quality measurements. In addition to this, the team and I continued to refine and nail down our design requirements for Jaehyun’s presentation next week, which will be important for our project trajectory. I also started working Read more…
This week, Jaehyun, John, and I continued to refine our parts list. We specifically focused on our planned LoRa network, researching how to use LoRaWAN and LoRa, as well as looking into how we wanted to put together our LTE board setup. For the cellular network we are planning to Read more…
