Open Hardware: CHIPS Alliance, Elk Audio OS, Raspberry Pi, Arduino and More

Submitted by Roy Schestowitz on Monday 11th of November 2019 03:57:45 AM
  • CHIPS Alliance announces technical milestones, three new workgroups including Chisel and the 3rd Chisel Community Conference

    CHIPS Alliance, the leading consortium advancing common, open hardware for interfaces, processors and systems, today announced the creation of Interconnects, Rocket and Chisel workgroups. In addition, a November verification workshop in Munich and a Chisel conference in January will be held giving engineers an opportunity to learn about open source development efforts in CHIPS Alliance. Lastly, the CHIPS Alliance toolchain and cores workgroups have made contributions to open source development tools.

    CHIPS Alliance is the project hosted by the Linux Foundation to foster a collaborative environment to accelerate the creation and deployment of open SoCs, peripherals and software tools for use in mobile, computing, consumer electronics, and Internet of Things (IoT) applications. The CHIPS Alliance project develops high-quality open source Register Transfer Level (RTL) code and software development tools relevant to the design of open source CPUs, RISC-V-based SoCs, and complex peripherals for Field Programmable Gate Arrays (FPGAs) and custom silicon.

  • Elk Audio OS goes open source with a Raspberry Pi development kit

    Elk Audio OS is an audio operating system from Elk (formerly MIND Music Labs) that can run plug-ins on hardware instruments and audio devices in realtime with low latency. The company has now made the system open source and has released a development kit for Raspberry Pi. This could be a good solution for hosting some of those CPU heavy software instruments and effects at an affordable price.

    You can get your hands on the Elk Audio SDK and Development Kit for Raspberry Pi today through the Elk Audio website, but the company is working on a beta version of the OS to be released in the upcoming weeks. The Raspberry Pi Development Kit includes a custom Elk Pi Audio Hat, which Elk say is “one of the most advanced pro Audio Hats in the markets with down to 1ms latency”.

  • Xaxxon’s OpenLIDAR sensor is tiny, inexpensive and open source

    Xaxxon’s OpenLIDAR Sensor is a rotational laser scanner with open software and hardware, intended for use with autonomous mobile robots and simultaneous-location-and-mapping (SLAM) applications.

    Xaxxon Technologies is a Vancouver-based developer and manufacturer of open source robotic devices. Its most recent offering is a standalone, OpenLIDAR sensor for robotic developers, educators and hobbyists. It consists of a Garmin Lidar-Litev3 sensor that is wired through a rotational slip ring, with stepper motor drive, two 3D-printed frame parts, and an Arduino compatible printed circuit board (PCB). The resulting offering weighs 180 grams and has a maximum range up to 40m, a sample rate up to 750Hz, a resolution of 1 to approximately 2.5cm and a scanning speed up to 250 RPM.

  • Traffic Updates On The Seven Seas: Open Source Chart Plotter Using A Raspberry Pi

    Automatic Identification System (AIS) is a GPS tracking system that uses transponders to transmit a ship’s position data to other ships or receiver stations in an area. This is used for collision avoidance and by authorities (and hobbyists) to keep an eye on shipping traffic, and allow for stricken vessels to be found easily. [James]’ DIY chart plotter overlays the received AIS data over marine charts on a nice big display. A Raspberry Pi 3B+, AIS Receiver Hat, USB GPS dongle and a makes up the core of the system. The entire setup cost about $350. The Pi runs OpenCPN, an open source chart plotter and navigation software package that [John] says is rivals most commercial software. As most Pi users will know the SD card is often a weak link, so it’s probably worth having a backup SD card with all the software already installed just in case it fails during a voyage.

    We’ve seen AIS receiver stations built using the RTL-SDR, as well as a number of projects around the AIS equivalent in aviation, ADS-B. Check out [John]’s video after the break.

  • The Open Source Smart Home

    [Tijmen Schep] sends in his project, Candle Smart Home, which is an exhibit of 12 smart home devices which are designed around the concepts of ownership, open source, and privacy.

    The central controller runs on a Raspberry Pi which is running Mozilla’s new smart home operating system. Each individual device is Arduino based, and when you click through on the site you get a well designed graphic explaining how to build each device.

  • 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.
