Open Hardware: Arduino and RISC-V

  • No opponent nearby? Not a problem! This automatic chessboard lets you play others remotely | Arduino Blog

    Chess is an excellent game to play with friends, but what if you don’t have any to compete against nearby? This is what prompted maker Carlos Pendas to create an automatic chessboard that’s not only able to record which pieces got moved, but even move the pieces itself. This means you can play a game of physical chess with someone thousands of miles away.

    To begin, Pendas started out by designing and milling his own chess pieces with a special cutout underneath to hold both a weight and a magnet. The magnet is vital here as it’s what gets detected by the array of 500 Hall effect sensors underneath the board and moved by the articulating arm. After a player makes their move, an Arduino Nano reads which Hall sensors were activated and in what order to determine the piece moved. This data is then relayed to a Nano 33 IoT that communicates with a Lichess server to send movement and general game commands.

  • RISC-V Functional Safety Processor IP Core introduced by Fraunhofer IPMS and CAST

    The Fraunhofer Institute for Photonic Microsystems IPMS and semiconductor intellectual property provider CAST, Inc. announced the immediate availability of EMSA5-FS, a fault-tolerant embedded RISC-V processor IP core designed to meet the most stringent functional safety requirements of automotive, air-borne, and other safety-critical applications.

  • Intel Reportedly Interested In Acquiring RISC-V Firm SiFive

    Back in March during the announcement of Intel Foundry Services it was mentioned that SiFive and Intel were working together to allow RISC-V chips to be fabbed within Intel's facilities. Additionally, Intel Capital previously invested in SiFive during prior funding rounds. Now it turns out Intel is reportedly positioning to potentially acquire SiFive.

    According to a Bloomberg report out today, Intel has made an offer to acquire SiFive for more than $2 billion USD. The report is unconfirmed and said to still be early on in talks as well as other firms being potentially interested in acquiring SiFive otherwise there is also investor interest if they just pursue a new round of funding instead.

  • China's ISCAS to build 2,000 RISC-V laptops by the end of 2022 as nation seeks to cut reliance on Arm, Intel chips

    The Institute of Software at the Chinese Academy of Sciences (ISCAS) is working to build 2,000 laptops using the free and open-source RISC-V instruction set architecture by the end of next year, as the nation looks to reduce its reliance on foreign technology giants like Arm and Intel.

    First developed at the University of California, Berkeley, in 2010, RISC-V is an open-source alternative to proprietary processor architectures including Arm and x86. Anyone is free to build chips based on RISC-V, which can themselves be open or closed source, and anyone can modify or extend the architecture as they see fit.

  • 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.
