Open Hardware/Modding: Wilson the IoT Hat (Arduino), Purism, and COVID Patient Health Assessment Device

Filed under
  • Use your smartphone to control Wilson the IoT hat | Arduino Blog

    Wearable displays are nothing new, but many of them lack that all-important “fun” element. That’s why OlivierZ over on Instructables created Wilson the IoT hat. The smart hat contains a large 232mm by 22mm flexible LED strip on its front that prominently shows rainbow text across a 71×7 LED matrix. The whole thing runs on a single 9V battery, which powers an Arduino Nano, HC-05 Bluetooth module, and LED matrix. All of these components are nicely tucked away within the top of the hat to prevent wearers from seeing unsightly wires.

  • Software Updates that Respects Civil Liberties – Purism

    Yet-another reminder of how disrespectful Apple, Google, and Microsoft are with their software update process was highlighted to Android phones that were in Massachusets, USA. The unintentionally descriptively named “MassNotify” application was installed to all Android phones in Mass.—en masse—without consent.

    Mass Upgrade, Without Consent

    From a forced album install by Apple, to the forced upgrade to the Microsoft Edge browser, to the truth is stranger than fiction forced removal of the book 1984 from Kindle devices, mass forced upgrades/updates has been abused as technological dictatorship in the name of “security”. All technological advancements—even software updates—can be done where it respects the freedoms and civil liberties of humans. Not only can it be done, we can look at one of the earliest (and one of the most secure) operating system distributions and how they did software updates the right way.

  • This pocket-sized uses tinyML to analyze a COVID-19 patient's health conditions | Arduino Blog

    In light of the ongoing COVID-19 pandemic, being able to quickly determine a person’s current health status is very important. This is why Manivannan S wanted to build his very own COVID Patient Health Assessment Device that could take several data points from various vitals and make a prediction about what they indicate. The pocket-sized system features a Nano 33 BLE Sense at its core, along with a Maxim Integrated MAX30102 pulse oximeter/heart-rate sensor to measure oxygen saturation and pulse.

    From this incoming health data, Manivannan developed a simple algorithm that generates a “Health Index” score by plugging in factors such as SpO2, respiration rate, heart rate, and temperature into a linear regression. Once some sample data was created, he sent it to Edge Impulse and trained a model that uses a series of health indices to come up with a plausible patient condition.

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.
