  • Add an audio jack to Raspberry Pi 400 with the DACBerry 400 - CNX Software

    The Raspberry Pi 400 is a keyboard PC with most of the features of Raspberry Pi 4 SBC, with one of the exceptions being the lack of AV port. But you can now add a 3.5mm audio jack to the Raspberry Pi 400 through the DACBerry 400 S expansion board that connects to the 40-pin GPIO header.

    It’s a neater way than using a cheap USB audio dongle with microphone and headphone jacks, as it takes less space, and does not occupy any of the USB ports from the Raspberry Pi 400, and it does not prevent you from using the GPIO header. It’s also better suited for headphones with both microphone input and analog stereo audio output into a single jack, and probably comes with better audio quality than the low-cost USB dongles.

  • Marvell 7040 based networking SBC features 10GbE port, 5G, and WiFi 6

    On Kickstarter: Globalscale’s $159 “Mochabin” SBC runs Linux on a quad -A72 Marvell 7040 with up to 8GB DDR4, 10GbE and 1GbE SFP, 4x GbE, WAN/PoE, 2x M.2, and an enclosure. A $199 model adds WiFi 6.

    Globalscale Technologies has announced a more powerful follow-on to its EspressoBin networking board. The Mochabin advances to a 1.4GHz, quad-core, Cortex-A72 Marvell Armada 7040, compared to the earlier quad -A53 Armada 3720, and offers more Ethernet ports including a 10GbE port. The Ubuntu or OpenWrt driven board is supported by the same EspressoBin.net community, and supports a variety of firewall, networking, SDWAN, and NAS applications.

  • Portenta H7 Lite Connected hits another sweet spot for pro users

    We launched the powerful Portenta H7 last year. The more targeted Portenta H7 Lite just a few weeks ago. And we’re back (already!), with another new product that fills the gap between the previous two versions.

    It’s known as Portenta H7 Lite Connected, but we like to call it “the best of both worlds.”

    The Portenta H7 Lite Connected is powerful, with integrated wireless connectivity, yet remains cost-optimized. You could think of it as the H7 with only one secure element and no high-resolution video interface. Or if you prefer, the H7 Lite with the ability to connect.

  • What’s On Your Bank Card? Hacker Tool Teaches All About NFC And RFID | Hackaday

    The Flipper Zero hacker tool is a multipurpose hacker tool that aims to make the world of hardware hacking more accessible with a slick design, wide array of capabilities, and a fantastic looking UI. They are struggling with manufacturing delays like everyone else right now, but there’s a silver lining: the team’s updates are genuinely informative and in-depth. The latest update is all about RFID and NFC, and how the Flipper Zero can interact with a variety of contactless protocols.

  • Hackable Smart Watch Is Also Open Source | Hackaday

    When they first came to market, many detractors thought that smart watches would be a flop or that there wouldn’t be much use for them. Over the past few years, though, their sales continue to increase as people find more and more niche uses for them that weren’t previously considered. The one downside to most of these watches is unsurprisingly their lack of openness and hackability, but with some willpower and small circuit components there are a few options available for those of us who like to truly own our technology.

  • 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.
