  • Cincoze DI-1100 is a fanless embedded computer with an optional external fan - CNX Software

    Cincoze DI-1100 is a rugged, modular embedded computer powered by an Intel Whiskey Lake processor that comes in a fanless metal enclosure with heat dissipation fins, but the company also offers an external fan that clips on top of the metal case for additional cooling when using high-power peripherals such as PoE cameras.

    Designed for autonomous robots, in-vehicle use, environmental monitoring, and other industrial applications, the computer supports -40 to 70°C wide temperature range, 9 to 48 VDC input voltage range, and comes with plenty of I/Os including two Gigabit Ethernet ports, six USB ports, two RS232/422/485 interfaces, as well as mini PCIe sockets, and CFM and CFI expansion modules.

    [...]

    The company offers Windows 10 and Linux operating systems and tested the operating temperature with PassMark Burn-In Test (100% CPU, 2D/3D Graphics) without experiencing thermal throttling.

  • Arduino IDE 2.0 release candidate exits beta, adds new features

    We’re looking for you to help with the Arduino IDE 2.0 Release Candidate (RC), which is available right now. Whether you’re an Arduino power user or new to microcontroller coding, there are a variety of ways that you can contribute to this exciting new release.

  • Blink an LED on ESP32 board with Tuya Link SDK - CNX Software

    Tuya is an All-in-one IoT Platform that enables the user to build smart IoT solutions by connecting devices efficiently, securely, and reliably. This is a getting started article to set up the Tuya platform with the Espressif’s ESP32 boards via tuya link SDK. Further, we use it to control an LED through an Android device. When the switch in the Tuya Smart App is turned ON, the LED connected to the ESP32 board glows and vice versa.

  • Active Pickguard Makes For A Great Guitar Mod | Hackaday

    The project reimagines the electronics of an electric guitar from the ground up. Instead of typical electromagnetic pickups, six individual piezo pickups are built into the bridge – one for each individual string. The outputs of these pickups is conditioned and then read by the analog-to-digital converter of a Freescale Kinetis K40. The DSP-capable chip can then be used to apply all manner of effects. [Eli] demonstrates the guitar providing an uncanny imitation of an acoustic guitar, before demonstrating jazz and overdrive tones as well.

  • New Pi Zero Gains Unapproved Antennas Yet Again | Hackaday

    We’ve only started to tap into the potential of the brand new Pi Zero 2. Having finally received his board, [Brian Dorey] shows us how to boost your Pi’s WiFi, the hacker way. Inline with the onboard WiFi antenna can be found a u.FL footprint, and you just know that someone had to add an external antenna. This is where [Brian] comes in, with a photo-rich writeup and video tutorial, embedded below, that will have you modify your own Zero in no time. His measurements show seeing fourteen networks available in a spot where he’d only see four before, and the RSSI levels reported have improved by 5 dB -10 dB, big when it comes to getting a further or more stable connection.

    [...]

    This trick should be pretty helpful if you’re ever to put your new Pi Zero in a full-metal enclosure. Curious about the Raspberry Pi antenna’s inner workings? We’ve covered them before! If you’d like to see some previous Raspberry Pi mods, here’s one for the Pi 3, and here’s one for the original Zero W – from [Brian], too!

  • Atari 130XE Keyboard Now Goes Clack | Hackaday

    Performing a resto-mod on a beloved piece of childhood technology can be quite a ride. In [Bertrand]’s case, it was the keyboard to their Atari 130XE. Although it has those cool double-shot keycaps, they’re hiding a crappy membrane underneath that could really benefit from a mechanical upgrade. Relax — the membrane part was broken.

    [Bertrand] designed and printed some new stems for Kailh box pinks that can accept both of the two known variants instead of the standard Cherry MX receptacle. He also made a new PCB (natch) and a keyboard adapter to replace the membrane interface, and had a steel keyswitch plate custom cut. The so-called Atari 130MX mod can be used with an Atari 130XE computer, or as a regular keyboard for a PC if you solder in a Pico.

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.
