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.

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 – 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.

This project, although simple, contains several elements essential for working with Arduino and in general with microcontrollers. In addition to working with the RGB diode, the project involves using the analogWrite function to work with (certain) digital pins. Using this function implies the use of PWM signals, and also includes usage of user functions.

In the age of classic cameras and darkrooms, photography involved developing images in light-proof rooms using chemical mixtures. To ensure successful image development, preventing light from entering the darkroom was crucial. This project involves developing an electronic circuit to control the operation of two LEDs, indicating the darkroom’s availability.

In today’s tech-driven world, laptops have become indispensable. They offer numerous benefits like portability and compactness. However, they also come with certain drawbacks. One major disadvantage is the limited battery life, and another significant issue is the small screen size. When you’re accustomed to working on a 27-inch desktop monitor, a laptop screen can feel quite cramped.

I have been using Fedora Linux for some time now. I switched from Arch Linux in search of some more “peaceful” distribution. However, I’ve been using Arch for too long to accept the KDE spin of Fedora that comes with a bunch of bloatware by default. I searched and of course found a tutorial for a minimal installation of the KDE Plasma environment on Fedora. I wrote about it almost a year ago, and now a new version is coming!
