Raspberry Pi analog input board has weather station option

Filed under
Linux

RasPi.TV has Kickstartered a $12 “RasPiO Analog Zero” Raspberry Pi add-on board the size of an Raspberry Pi Zero. It offers eight 10-bit analog inputs.

The RasPiO Analog Zero has surpassed its Kickstarter goals, and is available through May 31 starting at 8 Pounds ($12). Designed for reading up to eight analog sensors simultaneously on a Raspberry Pi, the add-on board is matched to the size of the 65 x 30mm Raspberry Pi Zero. However, it plugs into any Pi with a 40-pin expansion connector, and can work with older 26-pin Pi models with the help of an adapter.

Everything you need to know about Linux Commands

Filed under
Linux

It won't be long after starting to use Linux that you ask a question and the answer begins with, "Open a terminal and..." At this point, you may be thrown into an alien environment with typed Linux commands instead of cheery-looking icons. But the terminal is not alien, it's just different.

You are used to a GUI now, but you had to learn that, and the same applies to the command line. This raises an obvious question: "I already know how to use a windowed desktop, why must I learn something different?"

Google to bring official Android support to the Raspberry Pi 3

The Raspberry Pi 3 is not hurting for operating system choices. The tiny ARM computer is supported by several Linux distributions and even has a version of Windows 10 IoT core available. Now, it looks like the Pi is about to get official support for one of the most popular operating systems out there: Android. In Google's Android Open Source Project (AOSP) repository, a new device tree recently popped up for the Raspberry Pi 3.

Raspberry Pis, if you're not aware, are cheap, credit card-sized, single board ARM computers with a focus on education and open source software. Hardware hackers and DIYers love the Pi due to its open nature, small size, and plethora of ports and software.

What containers and unikernels can learn from Arduino and Raspberry Pi

Filed under
Linux
Server

There is a lot of interesting buzz around specialized container hosts, rump kernels, and unikernels because they hold the potential to revolutionize certain workloads (embedded, cloud, etc.). Keep your eye on this exciting, fast moving space, but cautiously.

Currently, unikernels seem quite similar to building printed circuits. They require a lot of upfront investment to utilize and are very specialized, providing benefits for certain workloads. In the meantime containers are quite interesting even for conventional workloads and don't require as much investment. Typically an operations team should be able to port an application to containers, whereas it takes real re-engineering to port an application to unikernels and the industry is still not quite sure what workloads can be ported to unikernels.

Here's to an exciting future of containers, rump kernels, and unikernels!

Is Ubuntu's Convergence the Future of Linux?

Filed under
Linux
Ubuntu

Convergence is not a word on everybody's lips. But if Canonical Software, the company that controls Ubuntu, has any say, it soon will be.

Others may be more skeptical.

Canonical describes convergence as "a single software platform that runs across smartphones, tablets, PCs, and TVs. It is designed to help make converged computing a reality: one system, one experience, multiple form factors."

CentOS 7 KDE: not for home users

Reviews

Whom can I recommend CentOS to? Probably to people I mentioned in the very beginning of this article: students who want to dedicate their life to system administration. You need to learn how to search for the answers, how to do things manually. That is your profession. That is your bread. CentOS gives you a brilliant opportunity to learn all of that along with learning the system itself.

But CentOS is not for home users who want things done quickly and easily, I'm afraid.

FOSS in 3D Printing

  • Open source wifi enabled 3D printer controller Franklin speeds up with new release
    3D printing hit the mainstream a few years ago thanks in part to the open-source 3D printer market. The origins of this transition had to do with expiring patents held by the traditionally held commercial 3D printing companies. Since then, several small businesses have sprung up around the emerging low-cost 3D printer market. Some of these companies embraced the open-source mentality, while others are seeking shelter with patents.
  • Hackaday Prize Entry: Open-Source Myoelectric Hand Prosthesis
    Hands can grab things, build things, communicate, and we control them intuitively with nothing more than a thought. To those who miss a hand, a prosthesis can be a life-changing tool for carrying out daily tasks. We are delighted to see that [Alvaro Villoslada] joined the Hackaday Prize with his contribution to advanced prosthesis technology: Dextra, the open-source myoelectric hand prosthesis.
  • BCN3D Technologies releases open source files for BCN3D Sigma 3D printer
    As our readers will know, an important part of the 3D printing community is the idea of accessibility. Of course, it is more than just an idea, as everyday makers around the world share their 3D designs and models for free, and even 3D printing companies exercise an open-source philosophy with DIY 3D printers and accessible models. Recently, Barcelona based 3D printer developer BCN3D Technologies decided to further embrace the additive manufacturing open-source philosophy with their latest initiative, Open Source 360º. As part of the initiative, the company has announced that it will share all of its engineering, design, and fabrication information used in the manufacturing of their flagship product, the BCN3D Sigma 3D printer.
  • Shellmo: Aquatic 3D printed robot for fun and education
    Recently I came across a very interesting open hardware project called Shellmo. What caught my eye was that it's a 3D printed crustacean that seems to have no apparent real world use, though with a little creativity I can see educational implications. Shellmo is a unique, almost cartoon-like creatures that could captivate the imagination of children while at the same time affording them an opportunity to 3D print their own robot. With the current emphasis on STEM in education, Shellmo appears to be the kind of project that would stimulate student interest.

    However, work remains to be done, especially on civil servants' desktops. "We started by replacing MSN Office", explains Villoslada. "Thanks to free office suite LibreOffice 5, we may overcome compatibility problems with documents coming in from different versions of MSN Office. We already have 1,000 Office licenses which are not necessary anymore, and we plan not to renew over 5,500 licenses purchased in 2007", he adds.
