Developed and deployed an Android Application using Java in Android Studio to track COVID-19 Statistics in Trinidad and Tobago. The backend of the application used Heroku to host a python webscraper while the data was stored in Google’s Firebase. The second version of this application was published to the Google Play Store which included basic reporting of the number of deaths, recovered, confirmed cases and active cases.
Developed and deployed a React web application which allows users to book their COVID-19 vaccination appointment at any vaccination site from the interactive map of Trinidad and Tobago. Twilio was used to allow users to sign up via SMS and get reminders or notifications about their appointment. A chatbot was also created using Rasa to answer FAQ type questions about the pandemic. The backend of the system was hosted on Heroku while the web application was deployed using Firebase Hosting.
Created an adventure RPG game using C# in Unity to teach users about financial literacy. The game featured only one scene where the main character would have to traverse the terrain to locate the Financial Wizard. The game development incorporated elements of visual scripting, animations, level design, audio design and storytelling. It also used C# coding for the main character control and interaction with environment objects.
Designed a Pulse Oximetry Sensor using an ESP32-01S Microcontroller along with various electronic components. A Real Time Operating System (FreeRTOS) was used on the ESP32 to manage all the tasks required to make the system operational. I2C communication was also used to be able to communicate with the Analog-to-Digital Converter (ADS1115). The project utilized a Power Budget to determine the expected operational time of the system which was determined to be 20 hours for a standard Duracell 9V battery.
Constructed a 4 Digit 7 Segment Display using four individual 7 segment displays. This project used a copper board and solder to secure the components. Resistors were appropriately sized to limit the current and protect the power supply in the event of a short circuit. An additional switching circuitry or multiplexer would be used to allow each digit on the display to have a unique value.
Researched and implemented using the various peripherals that come with the STM32F401 Development Board. These peripherals include USART, SPI and I2C Controllers, Analog to Digital Converters (ADC), Timers, Power Configuration, Permanent and Temporary Memory.
Designed and constructed a Voltage Regulator Circuit with Overcurrent, Overvoltage and Temperature Protection Circuits. The voltage regulator incorporated sensing circuits whose analog values were fed to an ADC which outputted the digital equivalent to a Nexys 3 Spartan 6 FPGA Board. The board also displayed the current, voltage and temperature values on a 4 Digit 7 Segment Display.
Designed and constructed a Single Stage H-Bias Amplifier using 2N3904 Transistor with a pure gain of 30. It also had a lower cut–off frequency of 105 Hz and maximum symmetrical swing of 17 volts peak to peak. The circuit was tested using an oscilloscope to derive the frequency response and bode plots.
Constructed a Flat Blade Screwdriver from 316 Stainless Steel Rod (Blade) and Teak Wood (Handle). The project used metal and wood turning lathes, vertical band saw and bench type drill press which were all located in the Mechanical Workshop. The finished product was a Flat Blade Screwdriver that could be used for Electrical Applications.
