Team Status Report 3/21

We didn’t hit any major new roadblocks this week. We spent a good chunk of time doing some preliminary testing on our 3D-printed clamp design, and the results were actually pretty encouraging. It feels sturdy enough to handle what we need. The biggest “problem” continues to be the overall mechanical fit. Now that we have the physical components, it’s clear that a lot of the parts we ordered don’t work great together. We also lost some testing time this week because we were missing a microSD card for the Pi, which kept us from really diving into the display and sensor integration.

Because the mechanical side is more complex than we originally thought, we’re making some adjustments to the chassis. We also realized the current mechanical connectors weren’t going to work, so we’ve ordered some new clamps and connectors to replace them. Moving forward, our plan is to pivot toward 3D printing a lot more of our own custom components rather than forcing the original parts to work. It’s a bit of a shift, but it’s the best way to make sure everything actually fits together securely.

Steven’s Status Report 3/21

This week, I spent most of my time digging through the electrical schematics for our Raspberry Pi port adapter. Since the adapter hub takes up all the GPIO pins, I had to trace everything back to figure out which ports we can actually use for our Hall effect sensor. It took a bit of research to find where those pins lead, but I needed to be sure we could read the sensor data properly. We also hit a small snag because we didn’t have a microSD card for most of the week, which meant I couldn’t actually get the Pi and display up and running for testing.

To be honest, we’re running a little behind. When we first made the schedule, we didn’t really account for how soon the first product demo was coming up. Most of the electrical stuff is in good shape, but the mechanical side is way more complicated than we thought it would be. Now that we have the parts, we’ve realized a lot of them aren’t going to work the way we planned, so we’re pivoting to 3D print more of the components ourselves. That mechanical design is definitely our biggest hurdle right now.

Now that we have the microSD card, my main goal for next week is to finally get the Pi connected and try to drive the LED display. I’m also going to start testing the Hall effect sensor to make sure we’re actually getting the data we need.
