[Charlotte] Status Update 12.7.2019

[Charlotte] Status Update 12.7.2019

What did you personally accomplish this week on the project? We got everything ready for the final demo this past Monday.  We did more testing of our whole system to gather metrics on our project.  We created a presentation.  I deliver the final presentation on Monday.  I finished some last touches on the CADed pieces of our project and laser cut out the boxes that would be storing our Sensor Hubs.  I also working more on the final paper. Is…

[Charlotte] Status Update 11.30.2019

What did you personally accomplish this week on the project? I have worked on the CADing wedges, cones, and boxes to hold our sensor system.  I have also worked on design schematics that will go into our final design doc, and I have put in work moving towards our final in-class presentation. Is your progress on schedule or behind? If you are behind, what actions will be taken to catch up to the project schedule? Alisha and I are right…

[Alisha] Status Update 11.30.19

I’ve been in lab nearly every day this week to get us demo-ready by Monday. It’s been quiet but productive over the holiday. [UI] From the perspective of the UI, I’ve separated Hunt Library into several zones, with one sensor hub per zone and each zone containing up to 12 carrels. Our demo will have 3 carrels representing 2 zones, with 1 desk in one zone and 2 desks in the other. I cleaned up the UI to show the…

[Alisha] Status Update 11.23.19

[Circuits] This week I implemented our Charlieplexing scheme with 4 pins and wrote up the Python code to drive those LEDs in groups (see photo below). We’ll be using a single LED per carrel and have them lit for available desks and unlit for occupied desks. From a design perspective, this is cleaner and less intrusive for a space that’s meant to be quiet and distraction-free. From a cost perspective, this allows us to maximize the number of carrels per…

[Charlotte] Status Update 11.23.2019

What did you personally accomplish this week on the project? I built 2 more study carrels so we now have a total of 3 study carrels built out of foam poster board.  I also painted sheets with the conductive paint.  I worked with Alisha to get the wiring ready so that she could solder the PIR sensors on a solderable breadboard.  I created wedges from left over scraps of foam at different angles that we used to test the best…

[Alisha] Status Update 11.16.19

[Problem-Solving] We had two primary problems to solve this week: (1) come up with a cleaner composition for connecting all our components together and (2) successfully incorporate the LEDs into our scheme (something we’d overlooked). Accessing the pins with the PiCap in place was cumbersome and offered limited access to the full range of RPi pins. We originally wanted to use a pin header between the RPi and PiCap; the intermediate pins we needed to access would be bent out at…

[Charlotte] Status Update 11.16.2019

What did you personally accomplish this week on the project? Towards the beginning of this week we made sure that at Pi Cap and PIR sensor worked properly when both connected to the same RPi.  We also updated the object that we are sending from our sub hubs to the UI, so it receives a list from each sub hub and that list is made up of objects that contain a zone, rpi ID, carrel ID, and the occupancy status. …

[Charlotte] Status Update 11.9.2019

What did you personally accomplish this week on the project? This week Alisha and I worked together on tasks more than we have in the past few weeks because we are in the process of bringing our whole project together.  Last Sunday and Monday morning we got ready for our demo at the beginning of the week.  It was on Wednesday that we actually demoed.  After that, I worked on researching how to write a script that would automatically execute…

[Alisha] Status Update 11.2.19

[UI] Incorporated the actual seat map of Hunt instead of the original generic map. Cleaned up some of the UI elements, adding a cleaner visual for the seat map and occupancy indicators. Started researching the feasibility of adding a live location feature to help students navigate to a given desk. [System] Spent most of the time working on connecting the sensor system to the app to make sure we have a completed pipeline from the PIR sensor to the sub-hub…

[Charlotte] Status Update 11.2.2019

What did you personally accomplish this week on the project? This week I was able to get wifi communication working between the Rpis.  Our focus for this past week/weekend was to get the pipeline of our system working.  By that I mean getting a sub hub to send information about the status of a PIR sensor to our main sensor hub that will then send this information to our UI built using React.  The majority of the pipeline is now…
