The Beginning of a Blockchain Journey: Ethereum, Solana, Rust, and Solidity

Welcome to my journey through the world of blockchain technology! As a developer passionate about innovation, I have always been intrigued by the potential of blockchain beyond cryptocurrency trading. My interest began when a former University assistant introduced me to the concept of decentralized applications (dApps) and their revolutionary possibilities. This series of articles will be my personal diary, a notebook in which I will document my experiences, challenges, and solutions as I delve into development on the Ethereum and Solana blockchains, using the Solidity and Rust programming languages. Whether you are a developer or just curious about blockchain, I hope you will find my journey inspiring and useful.

From Old Computer to CNC Machine: My DIY Story with Arduino

The Initial Spark: Why I Decided to Build My Own CNC Machine

A love of technology and a desire to create something practical and functional from what others consider waste — that was my motivation to start my first DIY CNC project. With a modest budget, but with a lot of enthusiasm, I decided to build a miniature CNC machine using an Arduino controller and recycled parts from an old computer.

Controlling Lightbulb: A Beginner’s Guide to Using Relays

Introduction to Relays and Arduino

Relays are electrically operated switches that allow low-voltage circuits to control higher-voltage devices. In the context of using Arduino, a popular microcontroller, relays serve as a crucial interface between the low voltage output of the Arduino and the high voltage required by lightbulbs. This capability is essential for projects that involve home automation or any applications requiring control over high-power devices while ensuring user safety and device integrity.

Migrating from Arch Linux to OpenSUSE: A New Perspective

As a long-time Linux user, I have always enjoyed the freedom this operating system provides. However, as time passes, needs and priorities change. For many years I have used Arch Linux , a distribution that fully introduces you to the world of control and customization. If you are not familiar with Arch, it is known for requiring the user to be fully responsible for the system – from installation to configuration of all components. This DIY philosophy is what appeals to many, including myself.

DIY Arduino Project: Room Occupancy Counter with 7-Segment Display

In this post, you’ll learn how to use a shift register (IC 74HC595) and a 7-segment display (model 5161AS) to track people entering and leaving a room. With these components and a few buttons, you’ll build a system that displays the current number of people in the room. Previously, I covered using the 7-segment display and shift register separately; now, I’ll show you how to combine them and add some cool effects to the display.

WordPress Multisite experience and blog setup

WordPress Multisite – the ability of WordPress to have multiple sites for the same installation immediately attracted me. I ran a blog in two languages using a WordPress plugin. The plugin offered basic translation of blog content, while advanced options were available in the paid version. By advanced options I mean URLs, tags and meta tags that mean a lot to SEO. Using the multisite feature eliminates the use of plugins and allows a greater degree of freedom in optimizing your WordPress site. A little more about migration to WordPress multisite follows in the rest of the text.
