  • Pico Wireless Pack adds ESP32 WiFi & Bluetooth module to Raspberry Pi Pico - CNX Software

    Pimoroni Pico Wireless Pack is an add-on board for Raspberry Pi Pico adding a MicroSD card socket and ESP32 WiFi & Bluetooth module to the popular MCU board.

    While it’s a nice idea to add wireless connectivity to Raspberry Pi Pico, ESP32 is a dual-core Xtensa LX6 processor clocked at 160 to 240 MHz with WiFi, Bluetooth, and plenty of I/Os that should be able to handle most tasks better than Raspberry Pi RP2040 dual-core Cortex-M0+ processor clocked at 48 MHz by default, although we’ve also seen it overclocked up to 252 MHz.

  • The MonKlock tells time using the Cistercian numeral system | Arduino Blog

    Way back in the 13th century, an order of monks known as the Cistercians created a unique numbering system that used a series figures and rotations to represent numbers up to 9,999 in just a single character. Because these numerals are so great in compact displays, using them in a dot matrix to display the current date and time was a no-brainer for danjovic.

    Danjovic combined a DS3231 real-time clock with an Arduino Nano to keep track of the current time, plus a large 4″ 5×7 LED matrix. All of these components were placed onto a custom PCB, along with two buttons that cycle between various modes and the time, day, month, and year. Finally, he made a wooden base that props up the PCB vertically and provides a convenient path to run the USB cable.

  • UG65 LoRaWAN gateway supports Node-RED, up to 2,000 nodes - CNX Software

    Node-RED is a popular flow-based, visual programming development tool originally developed by IBM for wiring together hardware devices, APIs, and online services as part of the Internet of Things.

    But despite being designed for the IoT, I’ve seldom seen Node-RED support for LoRaWAN hardware, the only exception being the Axon platform, a tiny WiFi & LoRaWAN board. But there’s at least one more option with Milestone IoT’s UG65 LoRaWAN gateway, launched late last year, getting a firmware update that adds Node-RED support.

  • 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.
