  • This wizard-themed book nook diorama features a face detection system, LEDs, and an ePaper display | Arduino Blog

    The fantastical world of wizards and magic is one that can be explored by reading a book, and what better way to represent this than building your very own interactive diorama within a reading corner? Well, that is exactly what Andy of element14 Presents created when he combined a small display, computer vision, and LED lights into a fun bookshelf adornment, which would accompany readers on their journeys.

    To begin, Andy had to figure out how to get a computer vision system into a space that is no larger than a shoebox, and for this task, he settled on using the Portenta H7 board plus its Vision Shield to gather images and classify them. His attempts to integrate a string of NeoPixels and an ePaper display module with MicroPython were unsuccessful, so this required a switch to only using C with TensorFlow Lite and some custom functions to take the framebuffers from the camera and determine if a face is present.

  • PocketView is an LED display that shows info through clothes and other fabrics | Arduino Blog

    hen receiving a notification on your phone, it can be a tedious process to take the device out of a pocket, unlock the screen, and then read the message. In order to make viewing simple information much faster, University of Waterloo researchers developed a small pocketable display that can shine images and text through fabric. This means seeing the current time or directions can be done far more quickly since all the user has to do is look down.

    The technology driving this system consists of an Arduino Pro Mini board, an HC-05 Bluetooth module for receiving data from a host phone, an 8×8 RGBW NeoPixel matrix, and a single 420mAh LiPo battery cell for power. All of these components were assembled into a single unit and placed within a 3D-printed enclosure that can easily fit into the user’s pocket.

  • Ecodesign Directive: FSFE calls for Device Neutrality and Upcycling of Software

    As contribution to the revisal of the EU ecodesign directive and to help understand the impact of software obsolescence, the FSFE publishes a study on the sustainability of software. The findings of the study culminate in five core demands for a more sustainable digitisation, covering the interplay of devices, software, and infrastructure.

    In the European Union we currently see a strong desire to make digitisation more sustainable with the European Commission aiming at making products more resource-efficient as well as circular economy methods applicable. The ecodesign directive from 2009 shall be updated in this regard with the "Sustainable Products Initiative" (SPI) that aims "to make products placed on the EU market more sustainable". The SPI will then serve as the main European product policy instrument, in the electronic sector additionally complemented by the "Circular Electronics Initiative" (CEI).

  • Sousaphone sound-reactive lights

    It is just a Teensy 4.0 I had lying around, together with an audio board, a basic lav mic, and a spare 74XX245 from my grab bag held together with hot glue and proto wire. It drives a cheapo 300 LED RGB strip that is VHB’d to the bell. I think the LEDs will only last a few more transport sessions, but with any luck I’ll make a slightly more polished revision with better longevity in the not too distant future.

Tails 4.25 Anonymous Linux OS Released with New Backup Tool for Persistent Storage

The monthly Tails releases continue, and Tails 4.25 is here to introduce a brand-new and simple backup utility to help users backup their Persistent Storage from the USB flash drive where they run Tails to another Tails USB stick. Contributed by David A. Wheeler, the new backup tool offers a graphical interface and automates the process described in the official Tails documentation on how to make a backup of your Persistent Storage via the command line. You can find it under System Tools > Back Up Persistent Storage. Read more

17.5 Years!

Tux Machines started in 2004. We're soon entering 2022.

AS we noted about a month ago, today is a very special day because it's a decimally-significant (quarter decade times seven) anniversary for us as we approach our 160,000th site node. Meaningful milestones are rare; they're superficial, but they help morale.

Tux Machines microwaveThanks to all those who regularly contribute stories (Marius, Arindam etc.) and to readers who have been gathering news about GNU/Linux through Tux Machines for as long as we've existed. Since our last server reboot we've served 115 million hits. Since the birth of the site it certainly adds up to several billions. Maybe we'll have over 200,000 nodes some time before our 20-year anniversary. Time will tell...
