  • Arduino Blog » Optimizing a low-cost camera for machine vision

    Arduino recently announced an update to the Arduino_OV767x camera library that makes it possible to run machine vision using TensorFlow Lite Micro on your Arduino Nano 33 BLE board.

    If you just want to try this and run machine learning on Arduino, you can skip to the project tutorial.

    The rest of this article is going to look at some of the lower level optimization work that made this all possible. There are higher performance industrial-targeted options like the Arduino Portenta available for machine vision, but the Arduino Nano 33 BLE has sufficient performance with TensorFlow Lite Micro support ready in the Arduino IDE. Combined with an OV767x module makes a low-cost machine vision solution for lower frame-rate applications like the person detection example in TensorFlow Lite Micro.

  • iPod Classic given new life with Raspberry Pi Zero W & Spotify

    Guy Dupont got a bunch of 2004, fourth-generation iPod Classic MP3 players from his mother-in-law, and instead of playing MP3 files on the media players, he decided to repurpose one with a Raspberry Pi Zero W to be able to stream music from Spotify over WiFi. The resulting project is called sPot (ess-pot), and looks just like an original iPod, but it’s a Linux device that can stream/search via Spotify with a UI written in Python and based on the original iPod experience.

  • [Old] BeagleBoard.org® and Seeed introduces the first affordable RISC-V board designed to run Linux

    BeagleV™ will be available for early access in March with larger availability in September. The early access version encompasses StarFive Jinghong 7100 SoC with powerful AI performance (3.5T NVDLA, 1T NNE), built-in ISP, 1 Gigabit ethernet, and a dual core 64-bit SiFive U74 RISC-V CPU with 8GB of LPDDR4 memory. It also has a dedicated hardware encoder/decoder supporting H.264 and H.265 4k@60fps, making it a perfect edge computing device with powerful AI capability. Supported by mainline Linux and a Debian-based BeagleBoard.org® open–source software image, BeagleV™ is ready for development out-of-the-box and prepared for the future.

  • [Old] RISC-V Comes To The BeagleBoard Ecosystem With Upcoming Beagle V SBC

    Seeed Studio pegs the cost of the board at $149 for the 8 GB RAM version, although currently you must apply and be selected to purchase a board in this early stage. It’s unclear if the price will remain unchanged after this first run; the product page notes a coupon code is necessary and the Seeed Studios article indicates this is an introductory price. However, the same article also lists the 4 GB RAM variant at $119. The BeagleBoard page shows a timeline of April 2021 for a “pilot run for community”.

  • 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.
