Biography

Even after many years, electronics remains a field in which I continue to find new challenges and opportunities for further development. From the first projects I built in the late 1970s using technical magazines and the available literature, I gradually progressed to the comprehensive development of modern electronic devices.

Today, I focus on the complete design of electronic circuits and printed circuit boards. This work includes developing the overall concept of a device, selecting suitable components, designing the schematic and PCB, and preparing complete manufacturing data. I place particular emphasis on correct functionality, reliability, manufacturability, serviceability, and high-quality mechanical and structural design. Clear and unambiguous production documentation for manufacturing, assembly, inspection, and possible servicing is also an essential part of every project.

My work also includes software development for ARM Cortex-M microcontrollers, primarily the STM32 family. In addition, I design and describe digital circuits implemented in CPLD and FPGA devices, including their implementation and subsequent verification in real hardware.

A significant part of my work is the design of control, user interface, and communication systems for amateur radio transceivers, receivers, and related equipment. These projects bring together my experience in analog and digital electronics, microcontroller programming, radio-frequency technology, and amateur radio operation.

I aim to develop each device into a fully functional prototype. I arrange the manufacture of printed circuit boards and also carry out manual assembly and soldering of SMD components. This is followed by initial power-up, measurement, testing, and, where necessary, modifications to the circuitry or software.

I also pay close attention to the overall mechanical and structural design of each device, including the CAD design of mechanical parts, front panels, the layout of controls, and the user interface. The development process also includes prototyping and the production of selected mechanical parts using 3D printing. In my view, a finished device should not only function correctly, but should also be well engineered, clearly arranged, practical, and pleasant to use on a daily basis.

I am also occasionally active in amateur radio and operate under the callsign **OK1XTG**. For me, amateur radio is not only a long-standing hobby, but also a valuable source of technical experience, inspiration, and new ideas for future projects.
