Intro

Hello, my name is Wilber Hernandez. I am a driven and detail-oriented undergraduate student pursuing a Bachelor Degree in Electrical Engineering at the University of Costa Rica, with a strong passion for software and hardware development. Robust problem-solving, programming and tutoring skills.

I divide my work time between university courses and freelance projects. Currently, I am more focused in developing a computer cluster using refribushed business class hardware for testing new skills in coding, networking, server management, and virtual machines. Also, I dedicate some time in tutoring in math and physics.

This site is aimed to present more information about skills, current and former projects. I built a personal web page to post content about my projects that can't be in a resume because it becomes easily bloated. CVs and resumes are meant to be for an introduction of yourself no longer than two pages, something meant to be read in less than 5 minutes.

I live in San Jose, Costa Rica.

Projects

Personal homelab: Electronics and computer workshop (2021).

Since I began my courses in engineering, I had a place to make projects for school and personal ones. It is a small apartment that didn't have a use after one of my sisters and her family left to his own house. Now I use it as a personal homelab, where I can test new skills in coding, networking, server management, and virtual machines. Also, I use it to store my tools and electronics components for my projects.

DC Motor Regulatory Control Design

  • Designing a DC motor regulatory control using PLECS and Code Composer Studio.
  • Conducting cascade PID control tuning using a Texas Instruments Delfino Microcontroller in a C2000 Launchpad XL Development Kit.

Smart Home Plant Irrigation System

  • Developing a smart home irrigation system using Arduino Uno controlling a DC motor water pump and two sensors to measure soil humidity and temperature.
  • Programming the system using C and integrating it with Thingsboard IoT platform for remote control and monitoring.
