Welcome to my website
About
I am a proactive entry-level hardware engineer with strong desire to apply programming and embedded systems knowledge in firmware product development. Determined with ability to work with all types of personalities. Knowledge in schematics, block diagrams, and control diagrams. Experienced in printed circuit board design and population with meticulous attention to detail. Committed to working both independently and as part of an engineering team. Looking for opportunity to work with cutting-edge technology and services organization.
Projects
These are some projects I've been involved in in the past few years involving software and hardware engineering, embedded systems, as well as engineering as a whole.
Robotic Nose
Summer 2019 - Current
This project is a currently ongoing research project. The goal of this project is to to be able to detect harmful chemicals in a harsh environment. This project uses a tank-like body and robotic arm to traverse its environment, with a camera to display the environment for the user. Alcohol sensors are being used in place of harsh chemical sensors at this stage so that the tank can take this data and move towards the source of the chemicals as a proof of concept. Wind and temperature sensors are being used to monitor the air through the nose, and an IMU is being used to detect the tank's orientation. When finished, this project will be used to detect pipes and chemical leaks to help repair these environments after a disaster.
Muon Detector on a Rocket
Fall 2019 - Current
This second iteration research project creates a low cost energetic charged particle detector compact in size compared to those used in the past for use in high-altitude and near-space applications. The sensor is comprised of a silicon photomultiplier and plastic scintillator which attribute to the compact and portable design. The overall system will use a 32-bit ARM microcontroller and will be launched on Blue Origin's New Shepherd Rocket, to reach heights it never has before. This sensor will detect charged particles up to 100km above sea level where it only reached 35km before, and is expected to measure charged particle flux as well as other charged particles through the mesosphere and the beginning of the thermosphere. Pictured below is the Spring 2018 version of the project created by current team members Nadine Martinez and Jonathan Kornich.

Head Motion Controlled Wheelchair
Fall 2018
The head motion controlled wheelchair project was intended to create a non-invasive solution to electric wheelchairs without hand controls. This project used a BNO55 IMU, Tiva TM4C123GH6PM micro controller, PIC16F877 microcontroller, and an XBee transmitter and receiver. To provide mobility to the wheelchair, we used 2 CIM motors, H-bridge drivers, a pulley system, and pipe grips and plywood to connect the apparatus to the wheelchair. In its final stage, the BNO55 was able to send information to the PIC16F877, through the XBee, to the Tiva, which then encoded the information received to the wheels so that the rotations on the IMU directly drove the direction and speed of the wheelchair.
Temperature and Humidity Detection
Spring 2018
This embedded systems project utilized a PIC12F1572 micro controller, a thermistor, and a HIH-4030 humidity sensor to detect the temperature and humidity values of the air. Â The humidity and temperature values were sent through ADC to the PIC, which interpreted this data and encoded its values into a frequency to be sent through an RF transmitter. This package was flown on a weather balloon 35km high, where it transmit data to a ground station in real time, along with other packages sending position data, so that the humidity and temperature data could be mapped to altitude in real time.
Amphibious Bicycle
Spring 2017
This mechanical engineering project, the goal was to create a bike that could function on both land and water. To do this, struts were welded together and bolted to the hubs of the bike to create fold able wings in the front and back of the bike. Two 5 gallon buckets were attached together vertically, and these were placed on the 4 metal strut structures by using ratchet straps. PVC pipe was cut on a table saw and attached to the spokes of the bike to create propellers. Ultimately, the bike was able to function as a bicycle outside of water, and the floats were able to fold down and provide support when in the water. The propellers didn't provide as much propelling force as was hoped, and the floats had a tendency to bend upwards due to a lack of an A-frame support above them, but overall the bike functioned in both land and water as intended, and was generally regarded as a success.
