This tutorial details enabling LVM2 on Ubuntu for Raspberry Pi. Ubuntu kernels for Raspberry Pi include LVM2 drivers natively, so no kernel recompilation or creation of initrd initramfs needed.
This tutorial provides step-by-step instructions to disable auto bed leveling (G29 commands) on the Creality Ender 3 S1 Pro when using PrusaSlicer with OctoPrint integration. Newer versions of PrusaSlicer automatically insert G29 commands into the start G-code for printers with bed leveling capabilities, which can cause unwanted auto leveling cycles during prints. By switching to Expert mode and editing the Custom G-code in printer settings, you can remove these commands entirely while maintaining compatibility with OctoPrint for seamless print uploads and monitoring.
Learn step-by-step how to expose your MySQL server running inside an LXD/LXC container on Ubuntu by creating a dedicated profile with a proxy device. This setup forwards traffic from the host’s port 3306 to the container’s MySQL instance, making it accessible externally without direct network bridging. Ideal for secure, isolated database hosting on any Ubuntu system.
Use Docker and Docker Compose on Raspberry Pi to run OctoPrint in a container and automatically start it when your Creality Ender 3 Pro USB serial adapter appears.
I decided to build a Git-based tool to manage Kubernetes secrets more efficiently. The whole idea was to automatically encrypt password and value fields in my Kubernetes YAML and Helm files before committing them into Git, and decrypt them effortlessly when checking out.
Configuring OpenVPN can often be a tedious task, especially when managing multiple clients with varying network settings. The OpenVPN Config Generator project offers a streamlined solution that automates key generation, static IP assignments, and configuration management to create your own private VPN LAN effortlessly.
Simple configuration generator for OpenVPN which supports static IPs, udp/tcp
This config generator is type of a tool I was always looking for. Actually you do not have to type some command to generate every simple config and you have all clients configurations in one config file - YAML. Every time you run a config generator it looks to YAML for a new config entries and generates only them. It automatically generates all certificates, not just client, but also CA authority, server keys, etc.
Recently, I ran into challenges backing up my MicroK8S cluster hosted on HyperV (essentially, my desktop workstation). While searching for backup tools for Windows, I found that most consumer-grade solutions—including Ashampoo Backup—are lacking, particularly for robust S3 support.
Discover how to configure MicroK8s to use NodePorts below 1024, a key step for setting up efficient ingress controllers like Traefik. This guide simplifies the process, ensuring a seamless integration of lower NodePorts in your Kubernetes environment.
Have you ever wondered how to measure battery voltage with a Raspberry Pi? The PCF8591 ADC (Analog-to-Digital Converter) module, which can be purchased for as little as 2 USD, provides a simple solution for measuring analog voltages via I2C on your Raspberry Pi. This tutorial explains how it works, how to deal with higher voltages like those from a lead-acid battery, and how to calibrate the setup to get accurate readings.
As Raspberry Pi projects grow more complex and critical, reliable backup power solutions are essential. While UPS HATs have been popular for seamless power backup, their limited capacity often falls short for demanding or long-duration setups. In 2025, new trends favor compact power stations, 12V mini-UPS systems, and advanced DIY battery solutions — providing longer runtimes, better efficiency, and enhanced monitoring for your Raspberry Pi ecosystem.
