  • How to Build Your Own Futuristic Smart Mirror

    A smart mirror can show your calendar, weather, and news like something out of a sci-fi movie. Powered by a Raspberry Pi, you can build your own with some simple tools and hardware.

  • Arduino launches new Nano board range

    Arduino has established itself as one of the leading small open source single-board microcontroller and microcontroller kit makers on the market with its designs popular with enthusiasts through to schools and universities. Founded in Italy, the company has launched its new Nano range of compact project boards that also happen to be among the cheapest it currently offers. They range in price from just US$9.90 for the Nano Every through to US$29.50 for the Nano 33 BLE Sense that includes Bluetooth as well as a range of proximity, gesture and environmental sensors.

    [...]

    Also new from Arduino is a MKR GSM 1400 Cellular SIM Kit. The Nano Every and the Nano 33 IoT will ship from mid-June while the Bluetooth-equipped Nano 33 BLE and Nano 33 BLE Sense will ship from mid-July.

  • An Open Source ESC For Brushless Motors

    For something basic like a brushed DC motor, speed control can be quite simple, and powering up the motor is a simple matter of just applying voltage. Brushless motors are much more demanding in their requirements however, and won’t spin unless driven just right. [Electronoobs] has been exploring the design of a brushless speed controller, and just released version 1.0 of his open-source ESC design.

    The basic design is compact, and very similar to many off-the-shelf brushless ESCs in the low power range. There’s a small PCB packing a bank of MOSFETs to handle switching power to the coils of the motor, and a big capacitor to help deal with current spikes. The hacker staple ATMEGA328 is the microcontroller running the show. It’s a sensorless design, which measures the back EMF of the motor in order to determine when to fire the MOSFETs. This keeps things simple for low-torque, low-power applications.

  • A Customizable Open Source Mechanical Numpad

    Mechanical keyboards with reduced key counts are all the rage these days, but while those streamlined input devices might look cool on your desk, there are times when the traditional number pad or navigation keys are quite handy. Rather than just going without, [Mattia Dal Ben] decided to put together his own mechanical auxiliary input device for when the main board just isn’t cutting it.

  • Little Printer returns as an open-source messaging device

    Berg’s Little Printer, an adorable internet-connected box that printed out tiny snippets of news, Instagram photos, and to-do lists, stopped working when the studio and its servers shut down in 2014. Now, design consultancy firm Nord Projects has brought it back to life with a brand-new app, and it added the ability to send messages between devices, as reported by Core77.

  • Perfecting the Open Source RC Controller

    For this entry into the 2019 Hackaday Prize, [Vitor de Miranda Henrique] is working on his own version of the ultimate open source remote control. His design follows some of the trends we’ve already seen in terms of outward design and hardware expandability, but also branches off into some new territory with features such as dual integrated displays.

  • HestiaPi Touch open source Raspberry Pi smart thermostat

    This month Google has made a number of changes to its Nest smart thermostat platform and services, some of which will have a profound effect on the integration of the thermostat with other Internet of Things services. If you are interested in moving away from corporate smart thermostats a new open source thermostat specifically designed for controlling HVAC and water systems has been created by the team at MakeOpenStuff.

    The HestiaPi smart thermostat is powered by integrated Raspberry Pi Zero W to offer wireless connectivity has been equipped with the 3.5-inch LCD display together with a host of sensors to monitor and control home heating and water. What she demonstration video below to learn more about the open source system that allows you to build your very own smart home thermostat and offer root access and increased privacy and security from the prying eyes of large corporations.

  • Raptor's Blackbird micro-ATX POWER9 System Is Ready To Take Flight This Week

    The much anticipated Raptor Blackbird is set to begin shipping over the days ahead. Blackbird is the lower-cost (compared to the Talos II Secure Workstation) micro-ATX motherboard for IBM POWER9 systems and offers open-source firmware as currently one of the most open, high-performance systems available.

    The Raptor Blackbird supports up to 8-core 160W Sforza POWER9 CPUs, two DDR4 ECC modules, one PCI Express 4.0 x16 slot (and one PCIe 4.0 x8), dual Gigabit Ethernet, 4 x SATA 3.0 ports, four USB 3.0 ports, and other standard connectivity.

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.
