  • Bluefin International Debuts R Series All-in-One Digital Signage System – rAVe [PUBS]

    Bluefin International has debuted the R Series all-in-one (player and display) digital signage system capable of running Android 10, Debian 10 and Linux.

  • Apollo Lake telematics system features Hailo-8 NPU

    Nexcom’s rugged, Linux-ready “VTC 1021” in-vehicle telematics system combines Apollo Lake with an up to 13-TOPS Hailo-8 NPU with GPS, 2x GbE, 2x optional PoE, 2x mini-PCIe, SATA, HDMI, USB, CAN, COM, and DIO.

    Nexcom continues to sample different types of edge AI NPUs for its embedded systems. In 2020, the company announced three Apollo Lake systems equipped with Google’s Coral Edge TPU mini-PCIe cards for AI acceleration, including the VTC 6222-GCIoT. Last month, Nexcom introduced a smaller AIEdge-X 100-VPU edge AI system for smart retail that combines Apollo Lake with up to 2x Intel Movidius Myriad X VPUs. The company has now announced a partnership with Hailo to launch an Apollo Lake based VTC 1021 in-vehicle system aimed at telematics and ADAS that is loaded with Hailo’s 3-TOPS per Watt Hailo-8 NPU.

  • Making a Board for the PIC32 VGA Signal Generation Project

    Although I have tried to maintain an interest in computing hardware over the last two years or so, both contemporary and somewhat older technologies, I haven’t really had much time or energy to devote to electronics projects. However, I was becoming increasingly bothered by my existing VGA signal generation project taking up space on a couple of solderless breadboards, demanding lots of jumper wires, and generally not helping me organise and consolidate my collection of electronics-related acquisitions, components, and so on. I was also feeling a bit bad for not moving the VGA project to the next step, which is what I had virtually promised to do. Having acquired a new computer in 2020 but not having really looked at KiCad since migrating to the new machine, I finally picked up the courage to set out translating my existing notes into a proper circuit diagram, reacquainting myself with KiCad’s peculiarities, and then translating this into an actual board layout.

    [...]

    Several weeks later, I received the boards in the post, thankfully without any customs fees or other charges. In the meantime, I had also ordered components that I needed from a supplier in the UK, Technobots, who happen to sell logic chips and other things that suppliers targeting the “maker” community tend not to bother selling. Thankfully also in this case, the components arrived without incurring fees and charges, although I had kept the value of my order fairly low. In Norway, the industrial lobby hate to see people importing things, often taking the tone that people should buy locally produced goods, but since nobody makes these things here, anyone “local” that sells them has to import them, and the result is often just the cheapest stuff at ridiculously high prices and some middlemen making all the money, rather than anyone earning a decent living out of actually producing anything. But anyway.

    The boards themselves were well made, as I have seen before, although I was disappointed with the “tabs” around the edge. When boards get made, people will tell you that they are all put on a big panel together and that they therefore need to be attached to each other somehow. The manufacturer will then typically spell out that apart from separating the boards by snapping them apart, they don’t do any further finishing work on the edges because we, the customers, aren’t paying for that level of service. However, I don’t remember the remnants of these inter-board connections – the tabs – being so awkward on previous boards from OSHPark. If I had to do anything before, I’m sure it just involved some gentle trimming, but these needed the application of glasspaper to grind down the tabs to be level with the actual board edge. Given the sub-millimetre tolerances involved in board fabrication, I find it perverse that such finishing would fall to someone – me or someone in the factory – to do this by hand.

  • This insane kinetic clock robot flips itself into position

    Displaying the time these days is trivial — you could do it with any Arduino board and a simple four-digit seven-segment display. But as humans, we crave novelty and it isn’t uncommon to see a clock that is more art than a practical timekeeping device. That is true of AKUROBATTO, which is an insane kinetic clock robot that flips itself into position.

    AKUROBATTO consists of a skateboard deck-shaped platform and a motorized robot. The robot acts like the hands of an analog clock, with two arms joined by a pivot joint. One can tell the time by judging the relative angular positions of the two arms. That sounds straightforward, but it gets more interesting when you realize that the pivot point between the two arms is not hard-mounted. So to change the angle between the arms, the robot must lock itself into place on the platform and then flip around.

  • Why I will never buy another Samsung device

    One day, I took the phone out of my pocket and the screen had a black part in the middle and the top half no longer responded to touch. When I got home the black part has expanded and kept growing. The screen clearly had failed from the fold. But hey, no worries, I had not dropped the phone, it was in case and I’ve only used the phone the way I’ve always used my other phones. So I’ll just send it to Samsung for repairs and all is good. Folding is still new tech so shit happens, I didn’t really mind.. until I received a response from Samsung repair: [...]

  • I’ve switched from Samsung phones and will never come back.

    Samsung has the steepest subsidies, because you get the phone, and then you realize that one of the things they do, it’s like buying a new PC with Windows and then having to root through 40 pieces of bloatware, spyware, and trial software, only with the Samsung phone, you can’t even disable a lot of it.

  • 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.
