After having fully recovered from the tolls of traveling, and addressing the feedback provided during our PDR presentation, we shifted our sights to the next goal: Prototype Inspection Day!

Prototype Inspection Day is a way for teams to present their current progress to other teams, mentors, and sponsors. For our prototype, we plan to present two physical models: an electrical model, which shows the interconnection of circuit boards and subassemblies, and a physical model, which gives a general idea for the size, shape, and form of the completed project. We plan to provide both CAD models and physical representations of both models, which will allow everyone to understand the general concepts and intricate details of both elements.

After multiple delays, we received our ESP32 development boards last week. We plan to heavily base our electrical model off of these boards- not only do they provide a comparable amount of I/O and features to the desired project, but they are also approximately the same physical size!

For the physical model, we plan to create a shell for our devices that matches DIN-rail dimensions, with multiple module slots. We plan to 3D-print our finalized model before Inspection Day, to provide a tactile representation to our audience. We created a rough concept here:

See you next week!
