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 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.

What did you personally accomplish this week on the project? Give files orphotos that demonstrate your progress. Prove to the reader that you put sufficienteffort into the project over the course of the week (12+ hours).

I discussed compressing the number of components we truly needed to get our MVP to work and helped the team limit the design of the bottle to only use 1 microcontroller placed at the very bottom of the water bottle. I also drew out a schematic of the final microcontroller setup, and discussed options on setting up the ultrasonic without having to place it at the very top of the bottle.

 

Is your progress on schedule or behind? If you are behind, what actions will betaken to catch up to the project schedule?

We are on schedule

What deliverables do you hope to complete in the next week?

We hope on having the CAD MVP product and work on directly connecting wires instead of a breadboard

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 orphotos that demonstrate your progress. Prove to the reader that you put sufficienteffort 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 betaken 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.

Matthew’s Status Report 2/24

What did you personally accomplish this week on the project? Give files orphotos that demonstrate your progress. Prove to the reader that you put sufficient effort into the project over the course of the week (12+ hours).

At the start of the week, I got started on soldering the SEEED microcontroller, as well as making modifications to the ultrasonic so that it could be directly connected onto the microcontroller, as well as accounting for reducing the length of the wires.

Unfortunately, Alan and I noticed the flaws of the SEEED microcontrollers, due to connection issues with our respective computers, so we are currently debating using a different microcontroller, such as an Arduino NANO BLE or Adafruit BLE models. We also reconfirmed the usage of the copper wire to be used as plates for a parallel capacitor setup.

 

Is your progress on schedule or behind? If you are behind, what actions will be taken to catch up to the project schedule

I am ahead of schedule with testing, but behind schedule with bluetooth testing and overall assembly thanks to the issue with the SEEED boards. I will have more time next week to work on the boards or even finding new microcontrollers

What deliverables do you hope to complete in the next week?

By next week I am hoping to have received a new microcontroller setup, and making modifications to the sensors that we have so that we can assemble all of the components together onto a breadboard setup.

 

Team Status Report for 02/17/2024

 

 

What are the most significant risks that could jeopardize the success of the project? How are these risks being managed? What contingency plans are ready?

The most significant risk for our project is related to the sensors since the only way to verify that they will work as intended is to directly test them out on a microcontroller. Our main contingency plan is to come up with different sensors that we can use in case our primary plan does not work, such as an implementation of piezosensors instead of an ultrasonic to estimate volume of liquid in the water bottle.

 

Were any changes made to the existing design of the system (requirements, block diagram, system spec, etc)? Why was this change necessary, what costs does the change incur, and how will these costs be mitigated going forward?

Most changes regarding the system were mostly hardware-related, as we found more sensors/utilities that we may potentially want for the product, such as a temperature sensor, gyroscope sensors,  and even an OLED display and solar panels. These changes were mostly for battery purposes, and potential costs may include the need to waterproof these specific parts as well.

 

 

 

Part A: … with respect to considerations of public health, safety or welfare. Note: The term ‘health’ refers to a state of well-being of people in both a physiological and psychological sense. ‘Safety’ is the absence of hazards and/or physical harm to persons. The term ‘welfare’ relates to the provision of the basic needs of people. (Alan)

Welfare – encourage more water drinking, help people track, prevent health issues

Health – reading about sensors, following 3-A standards

Our bottle helps promote welfare by promoting more water drinking. The act of carrying a water bottle can increase water intake and hydration [1][2]. Given that most Americans (86%) drink less than eight sixteen ounce glasses of water per day, and 47% of Americans drink woefully little water, at less than  three sixteen ounce glasses a day [3], increasing hydration could help prevent health issues among the population. This would be especially true with our smart bottle, that can track how much water a person drinks and motivate them with the social component of comparing their hydration levels with their friends.

As for health, we are carefully considering the materials we use. For sensors, we’ll abide by the 3-A standard – we are looking for sensors that have surfaces that are“smooth, non-porous, non-reactive, and easily cleaned” [4]. Similarly, we want a bottle that can be simply opened for cleaning, and be safely used in support. Reusable water bottles, when not properly cleaned, can accumulate dirt and mold [5], so we will make sure our bottle is easy to wash.

Part B: … with consideration of social factors. Social factors relate to extended social groups having distinctive cultural, social, political, and/or economic organizations. They have important to how people relate to each other and organize around social interests. (Erin)

With the recent Stanley and Hydroflask trend, people have been more and more concerned about their hydration levels. Many people have brought into this trend and Stanley has made over $750 million from water bottle sales. On Tik tok and instagram, people have begun advertising their “It Girl” lifestyle which is an extremely healthy lifestyle that includes a early wake up, healthy eating, working out, and staying hydrated. The need to become like these influencers have caused a craze to buy these bottles.

Our bottles will also fit into this social need. With a cute aesthetic to the app and a well designed bottle this could be easily advertised as part of the it girl lifestyle. We hope that we can support this demographic’s hydration goals by allowing them to better track their intake. Instead of figuring how many Stanley refills are 8 glasses of water and if they counted that matcha latte, we will be able to track that all for them. The social media aspect of this app will also be beneficial for the gamification and social connection for users. We hope that we can make this bottle accessible cost wise and safe for use especially since the user base can be young teens or young adults.

Part C: … with consideration of economic factors. Economic factors are those relating to the system of production, distribution, and consumption of goods and services. (Matthew)

Our product helps promote reusability. Rather than having to use one-time cups and discard them, it would be far more efficient to have a bottle to reuse which could also potentially keep track of the liquid being consumed.
Such usage can help reduce the amount of plastic/paper being wasted for one -time use, leading to more efficient usage of limited resources rather than wasting production costs. Furthermore, the reusable water bottle market has been headed towards a steady upwards trend, making a total of 8.3 billion dollars in 2020 with an estimated growth of 4.8 percent per year. This implies that there is a constant demand for reusable water bottles, and it is only fitting for a high-tech water bottle, with several consumer-friendly notifications to perform well in that market.

The product may not just directly impact the water bottle market, but other markets as well, such as the gym industry. The gym industry is all about achieving personal accomplishments, and the introduction of the smart water bottle can help them accurately keep track of the amount of water/liquid
that they actually intake to keep up with hydration goals. Therefore, consumption of this product would primarily be correlated to the people who are willing enough to keep track of their hydration. This is not an issue of concern, as the gym industry is also a growing market, with around 180 million
gym memberships, and is estimated to grow by 7 percent each year. Since the product will be part of a growing market, and also targets members who are part of a growing industry, this product can easily be distributed with the help of well-placed advertising

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 sufficienteffort into the project over the week (12+ hours).

I finalized research on the sensors we would be using, as well as organizing schematic drawings on how to set up the microcontrollers and potentially wiring everything through. A primary concern was how we were going to set up the different sensors, and the course of action we took was to divide the electronics into two different sections and use two microcontrollers for each section. Along with that, I started to help order parts, such as a second SEEED that we would use for our product

  • Is your progress on schedule or behind? If you are behind, what actions will be taken to catch up to the project schedule?

My progress is on schedule

  • What deliverables do you hope to complete in the next week?

By next week we hope to begin assembling the electronic components to create a prototype before trying to fit everything into a water bottle. I will be using the SEEED xiao to implement ultrasonic and gyroscope implementation at the same time. I will also be working with the team to turn in the Design Review draft looking at the feedback we received.

 

 

 

 

Matthew Choi Status Report 2/10/2024

  • What did you personally accomplish this week on the project?

I took a look at the parts that we needed and made a simple arduino model in order to test whether it was possible for different ultrasonic sensor models to detect water level to an accurate level. The process involved soldering wires and assembling parts within a breadboard. A different model of the microcontroller was used with the same amount of pins in order to estimate how many different items we could fit onto the microcontroller. I also ordered the bluetooth microcontroller that we will use for our product, as well as a new, waterproof ultrasonic sensor. I also CADed a brief model of a cylindrical water bottle we may potentially use, since it would be easier for us to estimate the volume of water thanks to the simpler shape.

  • What deliverables do you hope to complete in the next week?

 

I  hope to assemble the photodiode with the rest of the microcontroller assembly to start assembling a model without using a breadboard. We want to get a general idea on how many sensors we can fit inside of the SEEED microcontroller. I will also work on soldering specific wires to directly connect the microcontroller to the waterproof ultrasonic sensor
