We are currently on schedule
What deliverables do you hope to complete in the next week?
Next week, I’ll finish helping the team assembling the bottle and review any potential issues we have on our final assembly
Erin’s Status Report 4/20
What did you personally accomplish this week on the project? Give files or photos that demonstrate your progress. Prove to the reader that you put sufficient effort into the project over the course of the week (12+ hours).
This week I resoldered the bottle hardware due to a microcontroller breakage. I also cadded the bottle and worked on the calendar page of the app
Is your progress on schedule or behind?
On schedule
What deliverables do you hope to complete in the next week?
I need to work on the level seperation between different liquids on the app
As you’ve designed, implemented and debugged your project, what new tools or new knowledge did you find it necessary to learn to be able to accomplish these tasks? What learning strategies did you use to acquire this new knowledge?
I realized that hand soldering is really difficult to maintain and tends to break especially when the wires are tiny. We learned about a new connector that is tempory so things should not break as often

This week, I worked on getting the prototype ready for the MVP demo. I worked on 3d printing an entirely new bottle due to complications we had regarding the bottle starting to leak liquid despite the sealant and glue that we had used. I also helped get potential parts we would need, such as voltage regulators to power down the voltage needed from 9v to 5v or 3.3v depending on the circumstances. I also worked on the physical prototype with the team(as a team effort)
Is your progress on schedule or behind?
On schedule
What deliverables do you hope to complete in the next week?
We wish to have a new model of the bottle prototyped so that we can 3d print it, as well as making sure that we have enough space to fit in the sensors that we could not fit in on our MVP, such as the color sensor.
Now that you have some portions of your project built, and entering into the verification and validation phase of your project, provide a comprehensive update on what tests you have run or are planning to run. In particular, how will you analyze the anticipated measured results to verify your contribution to the project meets the engineering design requirements or the use case requirements?
We are planning to run tests on ultrasonic accuracy, determining if the amount of liquid that is currently being held is reliably close to the amount that is being estimated by the ultrasonic. The turbidity and tds will be used to help differentiate liquids by comparing them to the values that we got through reference liquids such as coffee, milk, water and such. The color sensor will be used to find a case where there are two different liquids with similar turbidity/tds values and differentiate them through visuals.
We will test these results in a classifier and check whether the results are within a reliable level of tolerance, and calibrate according to the data that we receive in return.

This week, I mostly worked on fabricating the bottle for the interim demo. I planned and drilled holes for the sensors, and sealed them in place with our food-safe sealant. It took a few days (the curing time for the sealant is 24 hours) and about three layers, but we now have a leak-free bottle! I also worked with Erin on soldering our circuit so we would no longer need a breadboard (she did most of the soldering; I did some of it, supported her on pieces that took two people, helped with planning for the circuit, modified the code to make connections easire, and tested the sensors once they had been soldered).
Is your progress on schedule or behind?
On schedule.
What deliverables do you hope to complete in the next week?
At the start of next week, I’ll focus on the interim demo – rehearsing my part of the presentation, helping define content, and troubleshoot any issues that come up so we can do to have a successful presentation.
I also plan on working some on connecting the battery, on working with Erin on the app to parse bluetooth data and implement the classifying logic in the app, and on the mechanism for testing whether the bottle is upright. We may need to purchase more pressure pads for this last part. I will also work on waterproofing solutions for the circuits in the bottom compartment (in case the sealant becomes leaky, which should not happen, but we will add a contingency measure to protect our circuit better).

Matthew’s status report 3/30/2024
What did you personally accomplish this week on the project? Give files or photos that demonstrate your progress. Prove to the reader that you put sufficient effort into the project over the course of the week (12+ hours).
I made CAD models of all of the assembled parts and 3d printed components to extend the bottom of the water bottle, as well as to hold the ultrasonic in place.
Is your progress on schedule or behind?
We are on schedule.
What deliverables do you hope to complete in the next week?
I hope to complete an MVP model and have a functioning product for the presentation
Erin’s Weekly Status Update 3/23
What did you personally accomplish this week on the project? Give files or photos that demonstrate your progress. Prove to the reader that you put sufficient effort into the project over the course of the week (12+ hours).
This week I wrote the app side code to connect the bottle to the app via bluetooth. Alan & I designed the bluetooth protocol for the bottle to app connection. Finally, I wrote app backend code to save past state data for water intake in the actual db and fixed some styling issues.
Is your progress on schedule or behind? If you are behind, what actions will be taken to catch up to the project schedule?
On schedule
What deliverables do you hope to complete in the next week?
I hope to complete the bottle to app communication protocol and test it next week. I also hope to make the calendar show different months instead of just the current one. I will support Matt and Alan once app mvp is done.
Matthew’s status report 3/16
What did you personally accomplish this week on the project? Give files or photos that demonstrate your progress. Prove to the reader that you put sufficient effort into the project over the course of the week (12+ hours).
I tested the new ultrasonic and capacitance measurements over several different liquids and types of cups to determine a correlation between capacitance and the liquid/cup material. Doing so required soldering the copper tape to wires, as well as setting up arduino code to accurately measure capacitance.
• Is your progress on schedule or behind? If you are behind, what actions will be taken to catch up to the project schedule?
Behind schedule, since the ultrasonic that we received was bugged, returning a constant value only
• What deliverables do you hope to complete in the next week?
I plan on having the ultrasonic and capacitance all working so that we can begin making an overall draft for the MVP, and start to turn the data we receive into more user friendly pieces of data such as volume
Matthew’s status report for 3/2 & 3/9
What did you personally accomplish this week on the project? Give files or
photos that demonstrate your progress. Prove to the reader that you put sufficient
effort into the project over the course of the week (12+ hours).
I developed the schematics of the electronic components, taking into account additional components and parts to switch out, such as a new microcontroller, OLED display, and removal of the accelerometer. Along with that, I helped edit the Design Review report, and tested out a modified ultrasonic sensor(we cut a bit of the wire from the ultrasonic that we got), discovering that it could not sense anything properly
• Is your progress on schedule or behind? If you are behind, what actions will be
taken to catch up to the project schedule?
We are slightly behind schedule, since we have to order a new ultrasonic/laser sensor instead of our old one to determine if it is compatible with our new microcontroller, but we will begin assembling the parts together as soon as they come
• What deliverables do you hope to complete in the next week
Roughly assemble all of the electronic components to determine if they can all work together, and order potential parts that we may have missed out on to get a final idea of what the CAD design will look like with potential wire mishaps.
