Europe’s Nordic nations have dominated the index. “Briefly put, (Nordic countries) are good at converting wealth into well-being,” In reaching No. 1, Finland nudged neighboring Norway into second place. →

https://www.hackster.io/delmans/ucameracube-c64263 Need for a custom camera module. Check out this intetesting looking project. uCameraCube is a parametric camera module build using OpenSCAD uCube library. It is build with Raspberry Pi and Raspberry Pi camera and comes in three versions, which vary in the type of optics used. Thin Lens version M12 Lens version T-Mount version →

https://blog.hackster.io/meet-the-new-raspberry-pi-3-model-b-2783103a147 This new version is based around the same 64-bit quad-core Broadcom BCM2837 processor as its predecessor, but now clocked at 1.4GHz rather than 1.2GHz. This means that the new Raspberry Pi board will run only moderately (around 15%) faster. It comes with the same 1GB of LPDDR2 SDRAM as its predecessor. Video: https://youtu.be/-Q_3pqoJWos More: →

Standard operating procedure in security disclosures; vendors are typically given at least a 90-day window to implement solutions. But in this case, AMD was notified a day ahead of the disclosure. →

Is Samsung Galaxy S9+ the fanciest Android phone at the moment? Only teardown will tell if this phone is a true contender, or just a weird AR Emoji machine. Read Samsung Galaxy S9+ Teardown by iFixit: two blades for changing aperture versus the usual five on normal cameras; battery, iris scanner, front cam are basically →

https://blog.arduino.cc/2018/03/13/you-can-now-use-arduino-to-program-linux-iot-devices/ Arduino Create users can now manage and program a wide range of popular Linux SBCs like the UP² board, Raspberry Pi, and BeagleBone. Today, at Embedded Linux Conference 2018, Arduino announced the expansion of the number of architectures supported by its Arduino Create platform for the development of IoT applications. With this new release, →

https://www.pv-tech.org/editors-blog/five-key-considerations-for-east-west-solar-design Around the world solar developers are turning array designs on their head and choosing to go east-west instead of south- or north-facing like their traditional cousins. While east-west solar arrays may have a reduced total output, the value of the electricity they produce is inherently higher in most markets – They are generating more →

I needed a motion detector for Arduino. I saw a cheap Microwave Radar Induction Switch Human Motion Sensor Module at DX (similar also available at Banggood at pack of 5). It advertises High Sensitivity for Arduino, Long Sensing Distance, Wide Sensing Angle for Detecting Moving Objects. Using this is a microwave sensor module that specifically →

https://www.edn.com/design/power-management/4460362/Finding-the-right-power-supply-technology-for-your-design In 2016, each person on the planet purchased an average of 111 semiconductor chips or integrated circuits. As the number of chips climbs, so does the need for greater power, space, and cost efficiency. In response, power device manufacturers have continued to evolve silicon-based technologies and develop new, wide bandgap materials such as gallium-nitride →
