  • ANAVI Gardening uHAT adds soil and other sensors to Raspberry Pi (Crowdfunding) - CNX Software

    We’ve been covering and reviewing ANAVI open-source hardware boards for several years now, either standalone boards based on ESP8266, or add-on boards for Raspberry Pi.

    The ANAVI Gardening uHAT is the latest board from Leon Anavi. It is a micro HAT designed for Raspberry Pi Zero to Raspberry Pi 4 SBCs that offers interfaces for soil sensors and other environmental sensors allowing measurements of soil moisture, atmospheric pressure and humidity, temperature with a waterproof sensor, and light intensity for gardening applications.

  • ZB-GW03 ESP32-based Ethernet Zigbee gateway works with Tasmota firmware - CNX Software

    ZB-GW03 is an Ethernet Zigbee Gateway compatible with eWelink mobile app and with a design similar to SONOFF ZBBridge gateway but replacing ESP8266 SoC by ESP32 SoC, and adding an Ethernet port.

    The ZB-GW03 gateway is apparently based on the same Silicon Labs EFR32MG21 Zigbee Arm Cortex-M33 chip and has been hacked to run Tasmota open-source software for people preferring more flexibility and/or integration with OpenHAB or Home Assistant open-source home automation frameworks via Zigbee2MQTT.

  • Arduino Orchestra Plays The Planets Suite | Hackaday

    We’ve seen a great many Arduino synthesizer projects over the years. We love to see a single Arduino bleeping out some monophonic notes. From there, many hackers catch the bug and the sky is truly the limit. [Kevin] is one such hacker who now has an Arduino orchestra capable of playing all seven movements of Gustav Holst’s Planets Suite.

    The performers are not human beings with expensive instruments, but simple microcontrollers running code hewn by [Kevin’s] own fingertips. The full orchestra consists of 11 Arduino Nanos, 6 Arduino Unos, 1 Arduino Pro Mini, 1 Adafruit Feather 32u4, and finally, a Raspberry Pi.

  • 3D Printed Research Robotics Platform Runs Remotely | Hackaday

    By patching Ubuntu Linux, and enabling preemptive multitasking for real-time scheduling, as well as carefully selecting Wi-Fi drivers, it was possible to get raw packets out to robot in about 1 ms, enabling control loop bandwidths of around 1 Khz. And, that, was fast enough to run at least sixteen motors in parallel.

  • Automated Window Blinds Using MQTT And Home Assistant | Hackaday

    Finnish software engineer [Toni] is on a quest to modernize his 1991 house, and his latest project was to automate the window blinds and control them using Home Assistant. Unless your blinds have built-in motors, most of the effort of such a project centers around how to integrate and attach the motor — and as [Toni] points out, there are tons of different blinds with all kinds of operating mechanisms. But once you solve that issue, half the battle is over.

    These particular blinds require less than one turn of the control rod to go from fully open to fully closed, and [Toni] selects a 270-degree range-of-motion, 20 kg*cm torque servo motor to drive them. He really wanted to install the motor inside the window, but it just wouldn’t fit. Instead, each servo motor is mounted in a custom 3D-printed case installed on the window frame just below the operating rod. An ESP8266-based controller box is installed above the window, hidden behind curtains, and operates all three servos.

  • Valve launches Deck Verified, to show off what games will work well on the Steam Deck | GamingOnLinux

    We've been wondering what Valve had planned to show off Steam Deck compatibility for games and now they've launched Deck Verified as their answer. Valve say they are reviewing the entire Steam catalogue on the Steam Deck, with each of them gaining a category that it falls under that will show up across Steam from the store to your own Steam Library. The ratings will be split across Verified, Playable, Unsupported and Unknown. This is good because there's a lot of reasons why games will mix between perfect and unplayable on Steam Deck and the Arch Linux-based SteamOS it ships with.

  • Valve Launches "Steam Deck Verified" Program For Games That Run Well On The Steam Deck - Phoronix

    Valve is introducing a Steam Deck Verified system for helping gamers find out what games have been verified to work well on their forthcoming AMD+Linux-powered handheld game console.

  • VKD3D-Proton 2.5 Released With Experimental DXR 1.1, More Games Working - Phoronix

    VKD3D-Proton as Valve's Direct3D 12 over Vulkan implementation for Steam Play's Proton is out with a big feature update. VKD3D-Proton 2.5 brings experimental, opt-in support for DXR 1.1 ray-tracing. DXR 1.1 isn't yet fully implemented but does add inline ray-tracing support and other features. DXR 1.0 ray-tracing meanwhile is now considered effectively feature complete with VKD3D-Proton 2.5.

  • VKD3D-Proton v2.5 is out for Direct3D 12 on top of Vulkan, improving DirectX Raytracing | GamingOnLinux

    VKD3D-Proton is the project that translates Microsoft's Direct3D 12 to Vulkan, another big part of Steam Play Proton and there's a new release out. If you wish to know more about Steam Play and Proton do check out our dedicated section. A continued focus of VKD3D-Proton is bringing up support for DirectX Raytracing (DXR). As of this version 2.5 the developer notes that DXR 1.0 "is more or less feature complete". A few weird issues are left and eventually the config variable to enable it will be removed when it's stable enough. Further work went into improving DXR 1.1 and it's now experimentally exposed, with it being enabled by setting VKD3D_CONFIG=dxr11. They say that DXR 1.1 cannot be "fully implemented" just yet, although the feature support missing doesn't seem to currently be used by games. As of now DXR 1.1 inline raytracing is also fully implemented.

  • Timberborn: a cute beaver colony sim with an unrewarding late game

    The game only supports Windows. However, it runs excellently on Linux in Steam Proton compatibility mode.

  • Swarming RTS Age of Darkness: Final Stand is in Early Access and works great on Linux | GamingOnLinux

    Age of Darkness: Final Stand is like a fantasy version of They Are Billions, and compared with the latter it runs great on Linux thanks to Steam Play Proton. No native Linux version here but honestly it runs so well you can't tell the difference, it's click and play thanks to Proton and as such a massive fan of real-time strategy games I couldn't resist playing this one myself. Note: key provided by Team17. The world in Age of Darkness is one of constant fear. Darkness brings out Nightmares, strange hellish creatures with a taste for flesh and destruction. It's a constant battle of preparation. Right now it only has a survival mode, which sees you build up a village as you attempt to survive each night. All the traditional elements of a base-building RTS are here with population management, resource gathering, army building and more. A game very much for those of you who like "turtling", where you focus on building up a heavy defence.

  • Playing Deltarune: Chapter 2 natively on Linux | GamingOnLinux

    So, some time ago Toby Fox released the second chapter of the Deltarune series. Sadly, as was the case with the previous chapter, this one too comes without official Linux support. However, if the [HeartShapedObject] is willing, there is a way to play the game natively on Linux, albeit without official support. The trick is essentially the same as I described back in 2018 when the first chapter of Deltarune was released. Essentially, Deltarune is made with the GameMaker engine, and you can do a "port" of games like that as long as you can find a compatible GameMaker runner binary to pair up with the game data.

  • War Thunder is getting more terrain deformation in the upcoming 'Ground Breaking' upgrade | GamingOnLinux

    Ground Breaking is the name of the next major update for War Thunder and it sounds quite exciting, with some game engine upgrades to allow for more terrain interactions and deformation. Not only will you see huge craters left over from some of the more explosive ordinance, you will also be able to push around the ground. Soil, sand and snow will be movable with your tanks, allowing you with a little patience to create your own little protective barriers. That's right, self-entrenching is going to be a thing. In the Ground Breaking update the developers will add in a new animation for vehicles digging in.

  • Hugely popular mobile roguelike Shattered Pixel Dungeon is coming to Steam | GamingOnLinux

    For the PC release the developer now has a Steam page live and they've confirmed it will have a native Linux version.

  • Arduino Nano Floppy Emulator For When Your Disk Is Not Accessible | Hackaday

    Among the plethora of obsolete removable media there are some which are lamented, but it can be difficult to find those who regret the passing of the floppy disk. These flexible magnetic disks in hard plastic covers were a staple of computing until some time in the early 2000s, and their drives could be found by the crateload in any spares box. But what about today, when there’s a need for a real floppy drive and none is to be found? Enter [Acemi Elektronikci], with an Arduino Nano based floppy emulator, that plugs into the floppy port of a PC old enough to have one, and allows the easy use of virtual floppy disks.

  • HarmonyOS development board shows up for $11

    Last year, we noted the Hisilicon Hi3861 based HiSpark WiFi IoT development board with supports LiteOS and HarmonyOS that was available in China for just under $10, or as part of a devkit with baseboard and modules for around $60. Although not very practical, buying from Taobao was possible, but there’s now what appears to be a new revision of the Hi3861V100 based HarmonyOS development board in a wider form factor on Banggood for $10.99.

  • These Open Source SCAMMERS are getting out of control! - Invidious

    No, Inkscape isn't a scam. In fact, it's the best vector illustration tool on the planet. But, much like Krita just a few weeks ago, scammers have registered official-looking domains that are meant to trick people into downloading and installing ransomware. It's sad to see and I can't think of many ways we can combat this besides raising awareness.

  • Josh Bressers: Episode 293 – Scoring OpenSSF Security Scoring

    Josh and Kurt talk about the release of OpenSSF Security Scorecards version 3. This is a great project that will probably make a huge difference. Most of the things the scorecards are measuring are no brainier activities. We go through the list of metrics being measured. There are only a few that we don’t think are fantastic.
