Hobby: Electronics & Prototyping

Status: Active / Ongoing

> Overview

Moving beyond software and industrial PLCs, I regularly design printed circuit boards (PCBs) and build embedded prototypes. This hands-on integration of microcontrollers, analog sensors, and custom 3D-printed chassis components allows me to bridge the gap between code and physical hardware.

> Active Bench Builds

• Geiger Counter: Designing a custom circuit to detect and measure ionizing radiation, processing the analog sensor data into a clean digital readout.
• Handheld Game Emulator: Building a portable retro gaming console from the ground up. This involves integrating display drivers, battery management, and custom input arrays on a compact footprint.

> Completed PCBs & Controllers

• 4-Axis Robotic Arm: Engineered the control logic for SG90 micro servos using Arduino UNO and Nano R4 platforms, complete with a custom PCB and custom-modeled components.
• Paludarium Weather Monitor: An automated controller built to manage a custom aquatic habitat. The logic monitors humidity and temperature while simulating realistic sun cycles and cloudy weather patterns.
• Solar Charge Controller: A custom board designed to safely regulate voltage and current from solar panels to a battery bank.
• Lighted Display Boxes: Programmable LED arrays and power distribution boards designed for custom display pieces.
