# Problem

There is a problem with the inconvenience associated with maintaining the perfect temperature of beverages. Drinks can cool down quickly, making them no longer enjoyable. The need to reheat a drink can also be time consuming and inconvenient especially with a packed schedule. There is also a problem with waste. Disposable cups and reheating drinks can contribute to waste and negatively impact our environment.
During our research, we found a smart mug called Embur Mug which can detect the temperature of the beverage and keeps it to a desired temperature. However, this mug is way too expensive for people to purchase with a price of 130 dollars.

# Solution

We propose the creation of a smart mug. Our design will improve the Embur Mug functionally and financially. Our mug will be equipped with a temperature control system that will automatically regulate the temperature of its contents to keep the drink at a desirable level. The mug will also have an app interface that will allow users to easily set up their preferred temperature, track their liquid intake and how fast they consume their liquid. The smart mug has the ability to keep drinks at the perfect drinking temperature and will eliminate the need for reheating. The smart mug will also track the amount of liquid in your cup at the moment. We will use a sensor to detect the weight of the liquid and display the number of ounces on your app. The smart mug not only improves the hot beverage drinking experience but also helps promote sustainable habits.



# Solution Components

## Subsystem 1 Temperature Sensor
- Will be integrating the industry standard temperature sensor by Maxim Integrated https://www.digikey.com/en/products/detail/analog-devices-inc.-maxim-integrated/DS18B20%2BT%26R/3478852?utm_adgroup=Sensors%2C%20Transducers&utm_source=google&utm_medium=cpc&utm_campaign=Shopping_Supplier_Maxim%20Integrated_8022_Co-op&utm_term=&utm_content=Sensors%2C%20Transducers&gclid=CjwKCAiAleOeBhBdEiwAfgmXf-hIaZj1YjASEiDZOg5dMMVtSrDlfEeoC1fjx_hQg3LjqtbzHDXz3xoCAXYQAvD_BwE
- Senses the temperature of the liquid

## Subsystem 2 Microcontroller with Wifi transceiver
- ESP8266 SoC board: standard Arduino generic microcontroller with a serial Wifi transceiver to regulate power, control the other subsystems, and send logs to a server that visualizes/analyzes data and handles app notifications.

## Subsystem 3 Warning System
- LED indicating the temperature scale of the beverage (on the mug)
- Send notification to phones if too hot or too cold. (user setting on the apps)

## Subsystems 4 Weight scale system
- Displays the number of ounces of liquid in the mug
- Give notification of refiling via LEDs on the mug

## Subsystems 5 Heating System
- Maintaining the beverage to a desired temperature/healthy temperature.


# Criterion for Success

- Detecting the temperature of the beverage and showing it on the mug via LEDs.
- Tracking drinking habits and visualizing the data on the apps
- Tracking the amount of liquid in the mug and giving refilling notifications via LEDs on the mug.

Prosthetic Control Board

Featured Project

Psyonic is a local start-up that has been working on a prosthetic arm with an impressive set of features as well as being affordable. The current iteration of the main hand board is functional, but has limitations in computational power as well as scalability. In lieu of this, Psyonic wishes to switch to a production-ready chip that is an improvement on the current micro controller by utilizing a more modern architecture. During this change a few new features would be added that would improve safety, allow for easier debugging, and fix some issues present in the current implementation. The board is also slated to communicate with several other boards found in the hand. Additionally we are looking at the possibility of improving the longevity of the product with methods such as conformal coating and potting.

Core Functionality:

Replace microcontroller, change connectors, and code software to send control signals to the motor drivers

Tier 1 functions:

Add additional communication interfaces (I2C), and add temperature sensor.

Tier 2 functions:

Setup framework for communication between other boards, and improve board longevity.

Overview of proposed changes by affected area:

Microcontroller/Architecture Change:

Teensy -> Production-ready chip (most likely ARM based, i.e. STM32 family of processors)

Board:

support new microcontroller, adding additional communication interfaces (I2C), change to more robust connector. (will need to design pcb for both main control as well as finger sensors)

Sensor:

Addition of a temperature sensor to provide temperature feedback to the microcontroller.

Software:

change from Arduino IDE to new toolchain. (ARM has various base libraries such as mbed and can be configured for use with eclipse to act as IDE) Lay out framework to allow communication from other boards found in other parts of the arm.
