  • Raspberry Pi CM4 powered system available as SBC or mini-PC

    Kontron announced a “Pi-Tron CM4” industrial mini-PC (or SBC) based on a Raspberry Pi Compute Module 4 with GbE and 10/100 LAN, 3x USB, 2x COM, CAN-FD, DIO, HDMI 2.0, MIPI-DSI/CSI, 40-pin GPIO, and M.2 B-key.

    Kontron unveiled an update to its Pi-Tron CM3+ industrial mini-PC. The Pi-Tron CM4 advances from a Raspberry Pi Compute Module 3+ to a Raspberry Pi Compute Module 4 (CM4). Like the Pi-Tron CM3+, which launched as an SBC but now offers an enclosure option, the Pi-Tron CM4 will be available as either an SBC or an embedded computer.

  • Making Laser Cut Raspberry Pi Cases Using The Atomstack X7 40W - The DIY Life

    Today we’re going to design and laser cut some new Raspberry Pi cases from 3mm plywood using the Atomstack X7 40W. This is a new laser engraving and cutting machine from Atomstack which is largely the same as their flagship X7 Pro, but with a slightly lower power 40W laser module.

  • RFID music player delivers vintage charm | Arduino Blog

    By every objective measure, with the possible exception of durability, today’s technology is superior to that of the past. That is certainly true of music players, with modern devices having the ability to stream almost every song ever recorded and the capability to do so with high fidelity. But old stuff looks cooler, which is why Redditor flatulentdisaster crafted this modern RFID music player that still delivers vintage charm.

    One could be forgiven for assuming that this device is legitimately vintage, because the wood enclosure looks like something straight out of the mid-century. If you saw this sitting on your grandma’s shelf, you would think it had been there since the ’50s. But the electronics and functionality are all modern. Users select from one of several RFID cards, each with a cassette tape label associated with a specific playlist. When the user taps the RFID card on top of the wood music player, it starts the associated playlist.

  • How to install go1.19beta on Ubuntu 22.04 – NextGenTips

    In this tutorial, we are going to explore how to install go on Ubuntu 22.04 Golang is an open-source programming language that is easy to learn and use. It is built-in concurrency and has a robust standard library. It is reliable, builds fast, and efficient software that scales fast. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel-type systems enable flexible and modular program constructions. Go compiles quickly to machine code and has the convenience of garbage collection and the power of run-time reflection. In this guide, we are going to learn how to install golang 1.19beta on Ubuntu 22.04. Go 1.19beta1 is not yet released. There is so much work in progress with all the documentation.

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
