  • This Arduino device will sort your M&M's by color | Arduino Blog

    If you were challenged to design a device that could sort M&M candies by color, how would you make it work? You might consider using machine learning, which has become accessible in recent years. There are even ML models available today that can run on Arduino boards. But Jack Monaco (AKA Jackofalltrades_) found a more elegant solution when he created this Arduino Uno-controlled M&M’s sorter.

    We perceive color based on the wavelengths of light that an object reflects. A white object reflects all visible wavelengths well. A black object doesn’t reflect any visible wavelengths well. A blue object reflects blue wavelengths better than others. This machine relies on those facts to detect the color of an M&M candy.

  • paperd.ink 4.2-inch ESP32-based e-Paper display ships with a 3D printed enclosure (Crowdfunding) - CNX Software

    We’ve covered a fair amount of connected e-Paper/e-Ink displays based on ESP32 WiFi & Bluetooth SOC including several Inkplate displays, with the latest Inkplate 6Plus model including a touchscreen, TTGO T5 displays with small sizes, or even the fully enclosed M5Paper ESP32 IoT development kit with a 4.7-inch touchscreen e-Paper display. There’s also Watchy ESP32 smartwatch with a 1.54-inch display if you really need something small.

    But here’s another option courtesy of Rohit & Prasad, two young engineers from India, with the paperd.ink 4.2-inch ESP32-powered e-Paper display that ships with an optional 3D printed enclosure.

  • Raspberry Pi CM4 based controller offers isolated serial and DIO

    OpenEmbed’s $159-and-up “EdgeBox-RPI4” industrial controller builds on the Raspberry Pi CM4 with GbE, optional WiFi/BT, HDMI 2.0, 2x USB, isolated RS485 and DIO and M.2 and mini-PCIe for NVMe and 4G.

    OpenEmbed, which has introduced products such as the RK3399-based em3399 module and emPAC-RK3399-EVB eval board, has launched a compact, semi-rugged edge controller and IoT gateway based on the Raspberry Pi Compute Module 4 (CM4). The EdgeBox-RPI4 is on pre-order at Seeed with July 7 shipment.

  • TI's AM64x powers three modules and two new HummingBoard SBCs

    TQ’s TQMa64xx, Phytec’s phyCore-AM64X, and SolidRun’s AM64x SOM modules run Linux on TI’s new FuSa-enabled Sitara AM64x with up to 6x GbE, 4x of which support TSN and fieldbus. The AM64x SOM also powers two new HummingBoard-T SBCs.

    Yesterday, we explored Texas Instruments’ new functional safety (FuSa) oriented Sitara AM64x SoC along with a pair of TI eval kits. Here we look at the first compute modules to showcase the AM64x: TQ Embedded’s TQMa64xx, Phytec’s PhyCore-AM64X, and SolidRun’s AM64x SOM. SolidRun’s AM64x SOM is also appearing on HummingBoard-T AM64X Base and Pro SBCs (see farther below).

    The headless, 16nm FinFET fabricated AM64x runs Linux on 1x or 2x 1GHz Cortex-A53 cores and offers up to 4x 800MHz Cortex-R5F cores for real-time duty. The SoC also supplies up to 2x programmable real-time units (PRUs) for managing up to 4x GbE ports with time-sensitive networking (TSN) and fieldbus protocols.

  • 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.
