Hello World! My name is Luis Fabregas and I am an electrical engineer and programmer with 16 months of software experience
and 4 years of academic electrical experience.
Here you will find my personal, student and work projects that showcase my wide set of skills ranging from working with
power electronics to creating user interfaces.

• Utilized OPAL-RT Hardware, HYPERSIM software, voltage/current amplifier and a feeder protection relay to develop
interactive laboratory exercises for students, enabling them to gain hands-on experience in Rapid Control
Prototyping and Hardware-in-the-loop simulation.
• Created comprehensive instructional manual for HYPERSIM and OPAL-RT, providing clear and concise guidance on
utilizing the software and hardware for analyzing and validating transient electromagnetic phenomena in power
system circuits.
• Designed, and implemented complex power systems using HYPERSIM to optimize system performance and stability,
while conducting extensive Hardware-in-the-Loop (HIL) testing with OPAL-RT hardware to validate the functionality
and reliability of power grid protection systems.
• Designed the Wilkinson Power Divider to divide the incoming signal into 2 equal parts by using even-odd analysis
to determine the characteristic impedance and the physical constraints of the transmission lines
• Fabricated the device by soldering microstrips and the SMA connectors to the circuit board and used a multimeter
to check if soldering connections were satisfactory
• Measured the performance of the device using VNAs and presented the S-parameter data in a report illustrating the
discrepancies that could have appeared in the device
• Constructed an embedded system that utilized a microcontroller, a time-of-flight sensor, and a stepper motor to
create a 3D model of your environment
• Programmed the embedded system in C based assembly to rotate the stepper motor and collect the spatial data
around the embedded system using the time-of-flight sensor when a button is pressed
• Transferred the data from the microcontroller to a PC (using a simple UART program) so it can be visualized in
programs such as MeshLab.
• Worked in a group of 5 to replicate the functionality of a pacemaker using a FRDM K64F board
• Modeled the different states of a pacemaker to optimize, verify, and validate the overall system design by
testing the embedded system in a simulation environment (in this case Simulink).
• Created a user interface using Python and QT Creator. Allowing the user to change the mode of the pacemaker and
various parameters, as well as display an electrogram of the atrial and ventricle signals.
• Documented the software development lifecycle specifying the requirements, design decisions, testing, and
anticipated changes to requirements and design.
• Collaborated with a team of 5 people to develop extra storage for our client’s wheelchair for the class
Engineering Profession and Practice
• Prepared detailed engineering drawings of the prototypes of our
wheelchair design
• Designed improvements for our storage on client’s wheelchair to maximize productivity and
reduce breakdowns
• Designed and developed a full-right-hand prosthesis, with the opening-and-closing of the fingers and thumb being
driven by a gearing mechanism that connects to a single motor
• Modeled the gears, hand frame and fingers,
assembled the mechanism and validated my design using Autodesk Inventor
• Utilized a high level of attention
to detail to construct engineering drawings of gear trains for prosthetic hand that are in accordance with ANSI
Standards
