  • 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.

Variscite unveils two i.MX8 QuadMax modules

Variscite announced Linux-powered “VAR-SOM-MX8” and “SPEAR-MX8” modules with an up to an i.MX8 QuadMax SoC plus up to 8GB LPDDR4 and 64GB eMMC. It also previewed a VAR-SOM-6UL COM. At Embedded World next week in Nuremberg, Germany, Variscite will showcase its Linux and Android driven i.MX8-family computer-on-modules, including new VAR-SOM-MX8 and SPEAR-MX8 modules that feature NXP’s highest-end i.MX8 SoC up to a QuadMax model (see farther below). We have already covered most of the other showcased products, including the 14nm fabricated, quad -A53 i.MX8M Mini based DART-MX8M-Mini. When we covered the DART-MX8M-Mini in September, Variscite didn’t have an image or product page, but both are now available here Read more

Programming: Developer Happiness, Rblpapi 0.3.8 and Python

  • Developer happiness: What you need to know
    A person needs the right tools for the job. There's nothing as frustrating as getting halfway through a car repair, for instance, only to discover you don't have the specialized tool you need to complete the job. The same concept applies to developers: you need the tools to do what you are best at, without disrupting your workflow with compliance and security needs, so you can produce code faster. Over half—51%, to be specific—of developers spend only one to four hours each day programming, according to ActiveState's recent Developer Survey 2018: Open Source Runtime Pains. In other words, the majority of developers spend less than half of their time coding. According to the survey, 50% of developers say security is one of their biggest concerns, but 67% of developers choose not to add a new language when coding because of the difficulties related to corporate policies.
  • Rblpapi 0.3.8: Keeping CRAN happy
    A minimal maintenance release of Rblpapi, now at version 0.3.9, arrived on CRAN earlier today. Rblpapi provides a direct interface between R and the Bloomberg Terminal via the C++ API provided by Bloomberg (but note that a valid Bloomberg license and installation is required). This is the ninth release since the package first appeared on CRAN in 2016. It accomodates a request by CRAN / R Core to cope with staged installs which will be a new feature of R 3.6.0. No other changes were made (besides updating a now-stale URL at Bloomberg in a few spots and other miniscule maintenance). However, a few other changes have been piling up at the GitHub repo so feel free to try that version too.
