  • Raspberry Pi 400 kit ships with 7-inch or 13.3-inch touchscreen display

    The Raspberry Pi Foundation has recently launched the Raspberry Pi 4 keyboard computer with impressive performance thanks to a well-designed cooling solution, and I think it’s a great tool for kids (and adults) who may want to carry a Raspberry Pi around. 

  • Shutdown button with Raspberry PI and Python - peppe8o

    Because of their low price, mini button switches are useful for many purposes. We have already analyzed how they work (ref. Using mini Switch Button with Raspberry PI and Python) and a funny use case (ref. Reaction Game (v2) with Raspberry PI and Mini Button Switch).

  • Arduino Blog » This remote-controlled storytelling apparatus is made up of Arduino-driven toy animatronics

    As an exhibit at the Phaneo Science Center in Wolfsburg, Germany, Niklas Roy and Felix Figus created a remotely-operated storytelling apparatus dubbed “Smart Fairy Tale.”

    When initiated, a little red ball rolls down the installation’s transparent tubing, triggering different interactions based on the interruption of light sensors along its path. 25 Arduino Nanos are used to control each individual animatronic part of the “story,” making the code manageable and allowing the overall machine to still work if there’s a malfunction in one section.

  • Pine64's PINECIL RISC-V soldering iron launched for $25

    We’ve previously mentioned PINECIL RISC-V soldering iron during Pine64’s release of PineCube open-source IP camera development kit, and the good news is the soldering iron is now available for $24.99 on Pine64 store together with optional sets of gross or fine soldering tips compatible with the one used with TS100 model The soldering iron is powered by GigaDevice GD32VF103TB 32-bit RISC-V general-purpose microcontroller and features a small display and two buttons for user interaction, as well as changeable tips.

CentOS is gone—but RHEL is now free for up to 16 production servers

Last month, Red Hat caused a lot of consternation in the enthusiast and small business Linux world when it announced the discontinuation of CentOS Linux. Long-standing tradition—and ambiguity in Red Hat's posted terms—led users to believe that CentOS 8 would be available until 2029, just like the RHEL 8 it was based on. Red Hat's early termination of CentOS 8 in 2021 cut eight of those 10 years away, leaving thousands of users stranded. As of February 1, 2021, Red Hat will make RHEL available at no cost for small-production workloads—with "small" defined as 16 systems or fewer. This access to no-cost production RHEL is by way of the newly expanded Red Hat Developer Subscription program, and it comes with no strings—in Red Hat's words, "this isn't a sales program, and no sales representative will follow up."

Linux at Home: Digital Music Production with Linux

We are told by our governments that in the current crisis the single most important action we can take is to stay at home and minimise the amount of contact with others. The new variants of Covid-19 are much more transmissible than the virus’s previous version. The advice to stay safe is therefore even more important. It’s only with everyone abiding by the law can we protect our health services and save lives. In this series, we look at a range of home activities where Linux can play its part, making the most of our time at home, keeping active and engaged. The change of lifestyle enforced by Covid-19 is an opportunity to expand our horizons, and spend more time on activities we have neglected in the past. Read more
