  • nRF9160 Feather LTE IoT and GPS Board Launched for $99

    The board is certified by the Open Source Hardware Association with the hardware licensed with CERN 1.2, mcuboot firmware with Apache 2.0, and documentation with CC-SA-4.0. While we noted in the introduction the board runs on Zephyr and nRF Connect SDK, support for other toolchains and languages should be released soon.

  • Arduino X-ray imaging phantom simulates lung movement

    Imaging phantoms are used to evaluate and test medical devices, such as X-ray machinery, where a human subject would be impractical and/or dangerous. In order to simulate the motion and deformation of a lung, Stefan Grimm created an Arduino-powered phantom at a materials cost of around $350 USD.

    Much of the project’s structure is printed with dissolvable PVA, used as a form for silicone that mimics tissue and plaster for bone. Movement is controlled via three linear and rotary actuator setups outlined here, and the structure can either be pre-programmed or manipulated in real-time using a USB cable and PC.

  • The Science Journal is graduating from Google — coming to Arduino this fall!

    Arduino and Google are excited to announce that the Science Journal app will be transferring from Google to Arduino this September! Arduino’s existing experience with the Science Journal and a long-standing commitment to open source and hands-on science has been crucial to the transfer ownership of the open source project over to Arduino.

    The Google versions of the app will officially cease support and updates on December 11th, 2020, with Arduino continuing all support and app development moving forward, including a brand new Arduino integration for iOS.

    Arduino Science Journal will include support for the Arduino Nano 33 BLE Sense board, as well as the Arduino Science Kit, with students able to document science experiments and record observations using their own Android or iOS device. The Science Journal actively encourages students to learn outside of the classroom, delivering accessible resources to support both teachers and students for remote or in person activities. For developers, the Arduino version will continue to be open: codes, APIs, and firmware to help them create innovative new projects.

  • This stepper-driven mechanical clock can be set to two different time zones

    Clocks normally tell you the time in your particular location, but what about that person that you know across the country or even on the other side the world? What time is it there? While it’s easy enough to do a web search or do a calculation, in order to find this out at an instant, Jeremy Cook made his own mechanical dual time zone clock.

    The device is powered by an Arduino Nano, which drives a stepper motor to advance each minute. Using physical gear reduction, dual hour gears move at 1/12th the rate of the minute indicator gear, which can be offset to the secondary time zone of your choosing.

  • ThinkCentre M75n IoT Nano Desktop Features a 6W AMD Athlon Silver 3050e Processor

    Earlier today, we wrote about AMD 3015e dual-core/quad-thread Zen processor with 6W TDP found in some upcoming education laptops from Lenovo. We also noted that two other recent 6W AMD processors had been introduced by the company AMD 3020e and AMD Athlon Silver 3050e.

    When looking for AMD 3020e I got ACER ASPIRE A314-22-A8ST 14″ laptop with 4GB RAM and 256GB SSD listed for 9,590 Baht ($309 inc. 7% VAT) – but out of stock – on several Thai websites, but after switching to a US VPN all product reference disappeared, except for Lenovo Ideapad 3 soon getting an AMD 3020e model. None of the laptops are available now, but at least that means AMD does not only target the education market with its 6W SKUs.

    [...]

    The company offers the computer with Windows 10 Home or Windows 10 Pro, but I suppose both Ubuntu or Red Hat Linux distributions should work just fine since those two operating systems are certified for the mini PC…

  • Wolf Audio Systems Releases Alpha 3 SX Music Server

    It features a modified-for-audio Windows 10 Pro or the new, proprietary Linux-based WolfOS operating system and offers 4TB storage capacity (expandable to 32TB), 24-bit and DSD playback capability, an upgraded Flux Capacitor 24 MHz master clock and additional improvements. It is a one-chassis design that fits easily into any audio or home entertainment system, and can play back a wide variety of stereo and multichannel audio formats including FLAC, WAV, AIFF, ALAC, SACD, DSF, DFF and (PCM) from 16 - 32 bits, 44.1, 88.2, 96, 176.4, 192 and 384 kHz audio and DSD Native up to DSD1024.

Plasma and the systemd startup

Landing in master, plasma has an optional new startup method to launch and manage all our KDE/Plasma services via a system --user interface rather than the current boot scripts. This will be available in Plasma 5.21. It is currently opt-in, off by default. I hope to make it the default where available after more testing and feedback, but it is important to stress that the current boot-up method will exist and be supported into the future. A lot of work was put into splitting and tidying so the actual amount of duplication in the end result is quite small and manageable. Read more

Mozilla Thunderbird 78.3 Is Out and You Can Finally Upgrade from Earlier Versions

Mozilla Thunderbird 78.3 open-source and free email client has arrived with more improvements and bug fixes, and you can now finally upgrade from older Thunderbird releases. When Thunderbird 78 launched earlier this year, it didn’t support automatic upgrades from version 68 or earlier. Automatic upgrade was blocked intentionally due to the revamped extension system that only supports MailExtensions, not classic extensions, to no break your Thunderbird installations. Three months later, Mozilla enabled automatic upgrades in Thunderbird with version 78.2.2 released a couple of weeks ago. Now Thunderbird 78.3 is out and it disables the installation of “legacy” MailExtensions. Read more
