  • Ferrari unveils open-source ventilator for COVID-19 patients
  • Hospitals Open Source the War on Covid-19

    As the coronavirus hit, staff at the Texas Children’s Hospital raced to invent a new device that would better protect doctors, nurses and patients during intubation procedures. The hospital then open-sourced their novel product design for others to use, and found a manufacturing partner called Sawbones that put their "Airway/Respiratory Containment System" up for sale.

  • Lilygo TTGO T-Watch-2020 is a Nicer Looking Arduino Programmable ESP32 Watch

    We’ve covered several ESP32 watches over the last year include TTGO T-Wristand, Watchy, and DSTIKE ESP32 watch. Those don’t really have the nicest looking design, and some people complained about various shortcomings including the difficulty to customize/program the watch.

    Last year, Lilygo introduced TTGO T-Watch smartwatch that, due to support for expansion boards, was relatively thick, but at least documentation and Arduino code samples can be found on Github. The company has now launched a slicker version with Lilygo TTGO T-Watch-2000.

  • This 3D printable “laboratory-grade” open-source microscope will set you back $18

    A team of researchers at the University of Bath, UK, have developed an open-source design for a 3D printable “laboratory-grade” microscope, costing as little as $18.

    The OpenFlexure microscope is a fully automated device with motorised sample positioning, focus control and a precise mechanical stage.

    As well as being easy to use, the microscope has also been designed to be more affordable than a commercial microscope. Its open-source, 3D printable design gives labs across the world the opportunity to 3D print their own precision microscopes as well, equipping them with the means to analyse samples and detect diseases.

  • Open Source Pick And Place Has A $450 BOM Cost

    Give your grizzled and cramped hands a break from stuffing boards with surface mount components. This is the job of pick and place machine, and over the years these tools of the trade for Printed Circuit Board Assembly (PCBA) have gotten closer to reality for the home shop; with some models diving below the $10,000 mark. But if you’re not doing it professionally, those are still unobtanium.

  • Open Source Raman Spectrometer Is Cheaper, But Not Cheap

    Raman spectrography uses the Raman scattering of photons from a laser or other coherent light beam to measure the vibrational state of molecules. In chemistry, this is useful for identifying molecules and studying chemical bonds. Don’t have a Raman spectroscope? Cheer up! Open Raman will give you the means to build one.

    The “starter edition” replaces the initial breadboard version which used Lego construction, although the plans for that are still on the site, as well. [Luc] is planning a performance edition, soon, that will have better performance and, presumably, a greater cost.

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.
