  • This guy created an open source 3D printable solution to A7III overheating issues

    We thought with the Sony A6500 that the overheating issue days with Sony would be over, but apparently not.

  • Someone Made an Open-Source Body Cooler for Overheating Sony Cameras

    Sony’s mirrorless cameras have been known to have overheating issues, prompting Sony to release firmware fixes and photographers to come up with novel solutions such as mounted sunshades. Now one guy has created an open-source design for a Sony camera body cooler.

    Brian Windle of Wilmington, Delaware, has shared a design for a Sony a7 III body cooler over on Thingiverse, where you can download all the files needed to 3D print and assemble your own.

  • Industry leaders to present Open Source on Arm insights at Linaro Connect Bangkok 2019

    Linaro Ltd, the open source collaborative engineering organization developing software for the Arm® ecosystem, announced today the keynote speakers for Linaro Connect Bangkok 2019. Joining the hundreds of engineers at the Centara Grand in Bangkok, Thailand 1-4 April 2019, will be industry leaders invited to share their insights into different segments and topics relating to the Arm ecosystem.

  • Open Source LIDAR Lets You Get Down To The Nitty Gritty

    If you’re unfamiliar with LIDAR, you might have noticed it sounds a bit like radar. That’s no accident – LIDAR is a backronym standing for “light detection and ranging”, the word having initially been created as a combination of “light” and “radar”. The average person is most likely to have come into contact with LIDAR at the business end of a police speed trap, but it doesn’t have to be that way. Unruly is the open source LIDAR project you’ve been waiting for all along.

    Unlike a lot of starter projects, LIDAR isn’t something you get into with a couple of salvaged LEDs and an Arduino Uno. We’re talking about measuring the time it takes light to travel relatively short distances, so plenty of specialised components are required. There’s a pulsed laser diode, and a special hypersensitive avalanche photodiode that operates at up to 130 V. These are combined with precision lenses and filters to ensure operation at the maximum range possible. Given that light can travel 300,000 km in a second, to get any usable resolution, a microcontroller alone simply isn’t fast enough to cut it here. A specialized time-to-digital converter (TDC) is used to time how long it takes the light pulse to return from a distant object. Unruly’s current usable resolution is somewhere in the ballpark of 10 mm – an impressive feat.

  • DIY Arduino weather station is open source, tweets and more

    Hackster.io member Jonty has published a new project providing details on how to build your very own DIY Arduino weather station. Aptly named TWIST the open source environmental monitoring system is capable of sending tweets and collecting meteorological data thanks to its include gas, rain, light, temperature and humidity sensors. The weather station takes approximately two hours to build and has been classed at an intermediate skill level project.

    Powered by the Intel Edison Board the Internet of Things weather station can be modified further and is compatible with a variety of sensors. All code, design files, schematics and PCB layouts are open source enabling those interested to share their modifications and new sensor support with others.

    “Ever wanted to monitor your city’s Current Weather Conditions, Carbon Footprint, Noise and Pollution levels? Do you want be a Climate Change Crusader or set-up your own Tweeting Weather Station and share your local weather conditions with the world?”

  • Internet, meet things: This starter kit is perfect for makers

    Spend any time at all around creative-minded techies, and you'll likely hear about Arduino. Whether you're making a simple motion sensor or a fully internet-controlled robot, Arduino is the platform of choice. If you're just diving in, we can't think of a better entry point than the Arduino Uno Ultimate Starter Kit & Course Bundle.

  • Arduino Enters the Cloud

    Love it or hate it, for many people embedded systems means Arduino. Now Arduino is leveraging its more powerful MKR boards and introducing a cloud service, the Arduino IoT Cloud. The goal is to make it simple for Arduino programs to record data and control actions from the cloud.

    The program is in beta and features a variety of both human and machine interaction styles. At the simple end, you can assemble a dashboard of controls and have the IoT Cloud generate your code and download it to your Arduino itself with no user programming required. More advanced users can use HTTP REST, MQTT, Javascript, Websockets, or a suite of command line tools.

    The system relies on “things” like temperature sensors, LEDs, and servos. With all the focus on security now, it isn’t surprising that the system supports X.509 authentication and TLS security for traffic in both directions.

Wine 4.0.2 Released

  • Wine Announcement

    The Wine maintenance release 4.0.2 is now available.

  • Wine 4.0.2 Released With 66 Bug Fixes

    Wine 4.0.2 is out today as the second stable point release to this year's Wine 4.0 cycle. As is customary for Wine stable point releases, only bug fixes are allowed in while new features come by way of the bi-weekly development releases that will lead up to the Wine 5.0 release in early 2020.

  • The stable Wine 4.0.2 release is now available

    If you prefer to walk on the calmer side of life, the Wine 4.0.2 release has been made available today. As it's just a "maintenance" release, there's no big new features which are reserved for the current 4.xx series currently at 4.14 released on August 17th. With that in mind they noted 66 bugs being marked as solved. These bugs include issues with Worms 2, Warframe, Rogue Squadron 3D, Settlers III, Mass Effect, F.E.A.R. 2: Project Origin, The Sims and plenty more.

28 facts about Linux for its 28th birthday

Nearly three decades ago, Linus Torvalds sent the email announcing Linux, a free operating system that was "just a hobby" and not "big and professional like GNU." It's fair to say that Linux has had an enormous influence on technology and the world in general in the 28 years since Torvalds announced it. Most people already know the "origin story" of Linux, though. Here's 28 things about Linux (the kernel and larger ecosystem) you may not already know. 1 - Linux isn't very useful alone, so folks took to creating Linux distributions to bundle user software with it, make it usable and easier to install. The first Linux distribution was Softlanding Linux System (SLS), first released in 1992 and using the .96p4 Linux kernel. You could buy it on 5.25" or 3.5" floppies, or CD-ROM if you were high-tech. If you wanted a GUI, you needed at least 8MB of RAM. 2 - SLS didn't last, but it influenced Slackware Linux, which was first released in 1993 and is still under development today. Slackware is the oldest surviving Linux distribution and celebrated its 26th birthday on July 17th this year. 3 - Linux has the largest install base of any general purpose operating system. It powers everything from all 500 of the Top 500 Supercomputers to Android phones, Chomebooks, and all manner of embedded devices and things like the Kindle eBook readers and smart televisions.

Quick Guide to The Awesome GNOME Disk Utility

GNOME Disk Utility is an awesome tool to maintain hard disk drives that shipped with Ubuntu. It's called simply "Disks" on start menu on 19.04, anyway. It's able to format hard disks and USB sticks, create and remove partitions, rename partitions, and check disk health. Not only that, it also features writing ISO into disk and vice versa, create ISO image of a disk. This tutorial explains in brief how to use it for 8 purposes. Let's go! Read more
