Hardware With Linux: Raspberry Pi, Arduino, Nordic Semiconductor, Gigatron and LibreRouter

Hardware
  • Ever evolving

    A recent core movement has been greatly helped by the Raspberry Pi Foundation. Makers around the globe had been tinkering more and more with open hardware – with the Arduino for one – as the price and complexity fell. The Raspberry Pi was the icing on the home-made cake, with all the abundant resources the Foundation brought with it. This issue we’re celebrating maker culture and helping all the many people that we expect will be wondering what to do with their new toys after Christmas. So jump on board and join the maker revolution and build something fun, something shared and something open source!

  • Customizable, Atom-based DIN-rail PC supports Linux

    Lanner’s “LEC-3034” is a fanless, Intel Bay Trail based DIN-rail box PC with up to 4x GbE, 4x USB, and 8x isolated serial ports plus SATA and mSATA storage and M.2 support for 4G.

    Lanner’s line of industrial computers, which includes its recent, Apollo Lake based NVA-3000 embedded vision computer, now has a new DIN-rail mountable PC that harkens back to Intel’s previous Bay Trail generation of Atom SoCs. The fanless, 169.5 x 127 x 69mm LEC-3034 runs Linux 2.6 or Windows 7 on a dual-core, 1.33GHz Atom E3825 and supports -40 to 70°C temperatures.

  • Nordic Thingy:52 Dev Kit (First impression)

    Today I'm playing around with a Nordic Thingy:52 Bluetooth 5 development kit from Nordic Semiconductor.

  • Gigatron – some assembly required

    I don’t know if 74 chips have got smaller since I was a kid or if I’ve just got bigger but this is a test of dexterity.

  • The LibreRouter project aims to make mesh networks simple and affordable

    In the city, we’re constantly saturated with the radio waves from 10 or 20 different routers, cell towers and other wireless infrastructure. But in rural communities there might only be one internet connection for a whole village. LibreRouter is a hardware and software project that looks to let those communities build their own modern, robust mesh networks to make the most of their limited connectivity.

    The intended use case is in situations where, say, a satellite or wired connection terminates at one point, the center of an area, but the people who need to use it live nearby — but well outside the hundred feet or so you can expect a Wi-Fi signal to travel. Often in such a case it’s also prohibitively expensive to run more wires or install cellular infrastructure.

Samsung, Red Hat to Work on Linux Drivers for Future Tech

The metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. Read more

  • 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.
