We believe that the most significant risk that could jeopardize the success of the project would be integration of the software and hardware end. We foresee potential compatibility issue with RPI Pico W’s communication with the cloud using blues notecard. The risk here is being managed by starting the hardware implementation side as soon as possible to test whether cloud connectivity is possible. Blues notecard is very well-documented with how to connect with RPI Pico W so William will deep dive into the documentation in Week 5. If the blues notecard does not work, we may alternatively change the hardware of the RPI Pico W into one that has built-in wifi capability. Blues notecard seemed more reasonable as our first choice due to its strong documentation with wifi connectivity and location data. Thus, using Blues notecard reduces the complexity on the hardware end.
Another important risk mentioned in William’s status report is the power consumption of the components on the glasses. We are hopeful that the selected 2000 mAH battery will be sufficient to continuously power all components on the glasses based off of William’s research of the consumption of the Blues Notecard and Arducam. However, complications may arise, and we may need to purchase a higher mAH battery to power the glasses.
A third significant risk may be the 2 MP arducam may not be good enough quality. William chose this camera due to its lower power consumption and strong resolution at 1600 x 1200. A contingency plan of this risk may be to upgrade our arducam to 5 MP with an image resolution of 2592 × 1944. However, due to the tradeoff of lower processing speed and higher power consumption, we are leaning towards 2 MP being “good enough” for our LLM analysis on the software end.
There has been no changes to the existing design of the system. We have been in the research stage and now we are focusing on the implementation stage next week. Currently, we don’t have any photos to display our progress, but next week William will start the RPI Pico W startup process while Dhruv and Rohit will work on the software end and have a UI ready via Figma or hand-drawing. Dhruv will additionally assist William in the connectivity/software aspect of the Pico’s connection to the cloud. We hope to implement and test this aspect ASAP because this is a key feature our design relies upon.
