Projects

I have designed and engineered a unique USB business card on a custom PCB. This device leverages my personal software creation, utilizing and adapting the V-USB library to emulate a keyboard (HID interface). When plugged in, it automatically opens Notepad and types out my CV. The key advantage of this approach is its ability to bypass security software restrictions, ensuring seamless functionality across various systems. 

I have designed an electronic wearable trinket inspired by the Romanian Mărțișor tradition, blending modern technology with cultural heritage. This piece was crafted with affordability and ease of replication in mind, making it an ideal gift to celebrate the occasion.

I have developed a sophisticated system designed to monitor and regulate the temperature in remote locations, ensuring that rooms with water pipes stay above freezing temperatures. The system employs an ESP8266 module as the "edge computing" device, which communicates via MQTT to a central server, a Raspberry Pi 3. The server-side logic is implemented using Node-RED, providing a flexible and visual interface for configuration, logging the on/off states of electric heaters, tracking power consumption, and serving as a central monitoring point for the system.

This project required a multidisciplinary approach, combining electronics, software development, high-voltage design, safety protocols, and system engineering to create a reliable and safe solution. This setup ensures energy-efficient heating and seamless control, making it ideal for environments where temperature regulation is critical.

This project was designed to monitor air quality, with a specific focus on detecting carbon monoxide levels. At its core, it used a Microchip PIC 8-bit microcontroller, providing a compact yet powerful platform for real-time data processing. The system featured a capacitive input method for intuitive control of a 16x2 LCD, displaying sensor readings and navigating a proprietary menu system.

The LCD was interfaced via I2C, utilizing an MCC (Microchip Code Configurator) driver that I enhanced to improve functionality and performance. One of the unique aspects of this project was its origin—it began as a challenge where I encouraged my friends to gift me sensors for my birthday, promising them something both interesting and useful in return.

This project combined embedded software development, sensor integration, and user-friendly interface design, resulting in a practical air quality monitoring device.

I have built a custom CNC machine based on the chassis from OpenBuilds, where I designed and fabricated the mechanical components. The electronics were sourced from various vendors to meet the specific needs of the machine. It is controlled via OpenBuilds CONTROL software, and I personally handled the configuration and calibration to ensure precision and optimal performance.

To enhance the machine's design, I integrated 3D printed parts that I created and adjusted plates, which were plasma cut from 1/4 inch steel for added durability and accuracy. This CNC machine reflects my hands-on approach and commitment to creating a reliable and versatile tool for various fabrication tasks.

I have designed and built a fully functional outdoor kitchen, blending various skills and techniques. The project included power electronics for the actuation of the kitchen lid, welding for constructing the sturdy frame, carpentry for the kitchen counter, and masonry for laying the tiles on the wall.

The kitchen features a gas stove and grill, both installed by me. To prevent heat damage to the wooden counters, I used a plasma cutter to craft a steel counter surrounding the grill, effectively isolating the heat. Additionally, I designed and cut lighting fixtures using the CNC machine I built, adding a unique touch to the kitchen's ambiance.

Throughout this project, my focus was on attention to detail, striving for a perfect balance of aesthetics and functionality. The experience was a valuable hands-on learning journey, bringing together my diverse skills in a practical and rewarding way.
