I have assembled several computers, some to order, some for personal use.

ETH tracker This is a simple project on PI zero. It uses an electronic link display to display the current price of Ethereum (cryptocurrency). It is updated every minute and is connected to Wi-Fi. Bluetooth Speaker This is an interesting project that I have done from 3D modeling to programming. First, I got acquainted with the existing products and outlined the main characteristics. Then I made some drawings and chose the best one. After that, I worked on the code and the electronic part. Then I modeled the case and the location of the electronics in 3D. Then I printed everything on a 3D printer and assembled it into a finished product. What I got, you can see.

I did this project when I was about 15 years old, but it still remains one of my favorites. This is a screwdriver made of two parts: an aluminum handle and a tip made of high-carbon steel. The handle was made of a length-cut extruded hexagon and sharpened on a central lathe. The high-carbon steel end was heated to a cherry-red color, flattened on an anvil, tempered, and then leveled with a band saw.

Remember, I told you that being driven by my scientific aspirations, one day I decided to create a small design workshop that would attract a variety of like-minded people. This is a place where we regularly meet and collaborate on various projects that have few clear goals, apart from the pure joy that practical training brings. Although we have created some great things, from radio-controlled cars to smart pet feeders and Bluetooth speakers, the main thing for me is actually the process, not the result. I want to tell you in more detail about metal projects that I can inspire other young scientists to put their knowledge and scientific research into practice.

This is my Christmas Java Jframe project. Using the Java feature of drawing objects, I created code to generate white circles (snowflakes) slowly moving down on a background resembling New Year’s snow.

Sitting at the kitchen table with my mom, I couldn’t help but feel grateful for the opportunity to have this kind of intense, but at the same time loving discussions between generations. We often hold opposing political views, and sometimes completely different points of view, but we have always enjoyed these debates and the opportunity to find justification and common ground that they offer. It was on this evening that the idea of artificial intelligence was touched upon. My mother, a relatively cautious person, was curious to learn about the potential impact that artificial intelligence can have on society, especially about the possibility of its self-sufficiency. Although she doesn’t have much technical knowledge in computer science, she has a deep understanding of society and its perception of artificial intelligence – often little more than a demonic robot from Terminator. My instinct in this debate, as with many, is to take…

One thing that really excites me is the idea of using “first principles thinking”: the practice of actively challenging every assumption I think I “know” about a given problem or scenario, and then creating solutions from scratch. Although this method certainly has limits, since all areas of knowledge are based on what was before, for my intellectual growth as a young design engineer, the process of bringing things to their fundamental truths and reasoning based on them was necessary.

Like many young design engineers, at an early age I assembled, disassembled and rewired all the electronic devices that came to my hand. After my first project at the age of 10 – a ventilator constructed from a disassembled radio–controlled helicopter – I was fixated on all sorts of self-funded experiments with the development of hardware and software: from repairing radio-controlled cars to creating an installation for mining Ethereum (by the way, my blog began with a story about mining). However, just at the moment when my extreme curiosity began to blossom, Russia invaded my native territory in the Crimea, and I suddenly found myself cut off from the information and materials that my impatient mind craved. Suddenly I found myself in an occupied state, where sanctions and harsh government intervention severely restricted my access to Google, YouTube (the most important source for many engineering projects) and the purchase of…

An independent project led by Ioannis (John) Kimissis, Professor of Electrical Engineering at Columbia University, on the development, visualization and marketing of a smart chessboard using a number of components, detailed drawings and complex calculations, presents all possible technical problems that need to be solved. The chessboard operates on sensors of a rheostatic switch (an electric switch operating under the influence of a magnetic field), LEDs and a microcontroller with a magnet and is designed to be high-quality and affordable. The main idea of the design is to create a system that is easy to reproduce and interactive for the user. Using rheostatic switches to determine the position of chess pieces (self-design of the pieces), the LEDs will demonstrate the moves on the computer. Figures moved manually will be highlighted on the computer screen, then the computer makes a move, which in turn is indicated by another LED. In addition…

Today on a run again with headphones Måneskin – Beggin’ With every stroke, I feel a step on the treadmill at 4:30 in the morning. With every word I feel that I need to complete another task, another breakthrough. This song makes me feel alive. And when it ends, I feel happy.
