  • Turn your hair trimmer into a musical instrument with Arduino

    Electric trimmers allow you to shed unwanted hair, with the side effect of a constant buzzing sound. This noise is related to the motor’s speed, which as shown in Device Orchestra’s video below, doesn’t necessarily have to be continuous. It could instead be tuned to play music.

    After removing the stock circuit board on a trimmer and attaching new leads, the concept was first proved out on a benchtop power supply, varying the motor speed and notes via the voltage level. This behavior was then duplicated by an Arduino Due and motor driver module, using PWM output to produce a rousing rendition of “When the Saints Go Marching In.”

  • Networking SBC boasts 2.5GbE, GbE with PoE and optional 5G and WiFi 6

    Wally’s $200 “DR6018 v2” router SBC runs Linux on a quad -A53 Qualcomm IPQ6010 and features 2.5GbE, 3x GbE, GbE with PoE, and 2x M.2 and SIM slots for 4G/5G and 802.11ax (WiFi 6).

    When Wally’s Communications launched its DR6018 router board in May, company reps noted it was a prototype that would be improved after customer feedback. The result is the DR6018 v2, which offers improvements such as a smaller size, dual SIM card slots, and a second M.2 slot, but with one less GbE port.

  • Tiny $10 module runs Linux on Cortex-A7 SoC

    SigmaStar’s $10 “IDO-SOM2D01” compute module runs Linux on its dual-core -A7 SSD201 SoC with built-in 64MB DDR2. The module offers 128MB to 2GB flash, dual LAN controllers, WiFi/BT, and an HD ready DSI interface.

    Chinese SoC manufacturer SigmaStar, a spinoff from MStar when it was acquired by MediaTek, has released a 29.5 x 29.5 compute module that costs only $10. The IDO-SOM2D01 module runs Linux on SigmaStar’s dual-core, Cortex-A7 SSD201 SoC clocked to 1.2GHz.The SSD201, which is documented along with other SigmaStar SoCs on Linux-chenxing, has 64MB of built-in DDR2. SigmaStar also sells a similar SSD202D SoC that boosts RAM to 128MB DDR3.

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.
