This week marked another major step forward as we continue refining both our hardware and system integration. With steady progress across electrical, mechanical, and communications efforts, we are getting closer to completing a fully functional prototype.

On the electrical side, we successfully finished the second PCB prototype and confirmed that it is fully functional. This iteration builds on what we learned from the first version and provides improved support for our system components. Having a reliable second prototype gives us greater confidence as we move toward full system assembly.

The mechanical team also made important progress by refining the enclosure design to ensure a proper fit with the PCB. Achieving a precise fit is critical for both durability and usability, and these adjustments help move the design closer to a final, manufacturable solution. We continued researching CNC manufacturing as a potential method for producing a stronger and more robust enclosure.

Our communications system also saw improvements this week. We enhanced the protocol to increase both security and reliability, which is essential for consistent device performance in real-world conditions. These updates will support more dependable data transmission as we continue testing and integration.

In addition to technical progress, we began preparing for the upcoming PID presentation by outlining key goals and identifying the content we need to communicate. This preparation ensures that we can clearly present our design, progress, and next steps.

The prototype coming together.
