  • This dad built an adaptive USB keyboard for his son and other kids with muscular conditions

    Having a disability can severely impact one’s ability to perform tasks that others do regularly, such as eating, walking, or even speaking. One maker by the name of ‘gtentacle‘ has a son who needs to use a ventilator constantly in order to breathe as he suffers from a myotubular myopathy, a disease that greatly impacts the strength of his muscles. Due to his condition, he is unable to talk; however, that that didn’t stop his father from coming up with a solution. This project involves five Logitech Adaptive Buttons and an Arduino Micro to type in letters for a text-to-speech (TTS) system to read.

    Up to 20 letters can be entered in total, and each one can be accessed with a grid-type system. For instance, the letter ‘T’ can be typed by pressing the 3 button followed by the 2 button. The ‘Enter’ command is sent whenever button 5 is the first key pressed. Thanks to the ATmega32u4, the system works with any device that supports a USB keyboard and has TTS software. The project’s creator even used it with Android Talkback.

  • Arm introduces Open-CMSIS-Pack and Keil Studio Cloud for MCU software development - CNX Software

    But apparently, not all components are, and Arm has now announced the Open-CMSIS-Pack project that will move part of CMSIS into the open project in collaboration with the Linaro IoT and Embedded Group.

  • Sync Google Drive with Arduino Science Journal projects

    Students and teachers can now sync Google Drive with their Arduino Science Journal experiments. This means you can access experiments from any device using your Arduino account. The brand new Google Drive integration is available through the latest app update.

  • Create your own low-cost contactless IR thermometer with Arduino | Arduino Blog

    In the age of COVID-19, being able to know when someone’s sick is vital, especially in countries where the disease is currently surging. It’s for this reason that Open Green Energy decided to build a battery-powered portable thermometer that not only takes a person’s temperature but also alerts other if it’s too high.

    At the heart of the device is an Arduino Nano that takes in temperature data from a GY-906 module and displays it on a 0.96” OLED screen. Additionally, there’s an IR emitter/receiver that detects when a person is in front of the thermometer so their temperature can be read. If the value falls within the acceptable range, a green LED lights up, but if the value is too high, such as in the case of a fever, a buzzer begins to sound, and the red LED turns on.

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.
