  • Purism Librem 5 Linux smartphone is getting another (big) price hike - Liliputing

    The Purism Librem 5 is one of only a handful of smartphones designed to run free and open source GNU/Linux distributions like Purism’s custom PureOS software. It’s also one of the most expensive, currently selling for $899.

    But it’s going to get even more expensive soon. In a move foreshadowed earlier this year, Purism recently announced that prices will go up this fall due at least in part to rising supply chain costs due to the global chip shortage. Customers who place an order after November 1, 2021 will have to pay $1199. And in March, 2022 the price will go up to $1299.

  • LOLIN S2 Pico - A compact ESP32-S2 board with an OLED display - CNX Software

    If you’re into small MCU boards with an integrated display, you’re in luck as LOLIN launched the S2 Pico board with ESP32-S2 and an OLED display about at the time same as LILYGO T-Display RP2040 board we covered yesterday.

    Wemos/LOLIN S2 Pico board offers WiFi connectivity, a 128×32 OLED display, USB Type-C port for power and programming, as well as the usual GPIO headers in a compact 50×23 mm form factor.

  • Harp Uses Frikin’ Lasers | Hackaday

    We aren’t sure if you really need lasers to build [HoPE’s] laser harp. It is little more than some photocells and has an Arduino generate tones based on the signals. Still, you need to excite the photocells somehow, and lasers are cheap enough these days.

    Mechanically, the device is a pretty large wooden structure. There are six lasers aligned to six light sensors. Each sensor is read by an analog input pin on an Arduino armed with a music-generation shield. We’ve seen plenty of these in the past, but the simplicity of this one is engaging.

  • Take a Look at This Optical Keyboard

    Making keyboards is easy, right? Just wire up a bunch of switches matrix-style to a microcontroller, slap some QMK and a set of keycaps on there and you’re good to go. Well, yeah, that might work for cushier environments like home offices and Hackaday dungeons, but what if you need to give input under water, in a volatile area, or anywhere else you’d have to forego the clacking for something hermetically sealed? Mechanical switches can only take you so far — at some point, you have to go optical.

  • The Many Ways To Solve Your Enclosure Problems | Hackaday

    Most projects around here involve some sort of electronics, and some sort of box to put them in. The same is true of pretty much all commercially available electronic products as well.

    Despite that, selecting an enclosure is far from a solved problem. For simple electronics it’s entirely possible to spend more time getting the case just right than working on the circuit itself. But most of the time we need to avoid getting bogged down in what exactly will house our hardware.

    The array of options available for your housing is vast, and while many people default to a 3D printer, there are frequently better choices. I’ve been around the block on this issue countless times and wanted to share the options as I see them, and help you decide which is right for you. Let’s talk about enclosures!

  • The Dramatic Rise of Esports Worldwide

    The Boiling Steam Matrix Room is full of surprises. Turns out that one of our readers, @Grazen, is in a senior leadership role at an Esports company. Since Esports are growing like crazy these days, it was a great opportunity to ask him for more details about the market and where everything is headed (and if Linux fits anywhere currently). [...] Adam: I play all of them, badly, but I keep trying. I would say Overwatch is my favorite to play but tough to master. Overwatch and League of Legends also work well via Lutris in Linux so it makes it easier for me to play as I don’t generally use Windows or OSX. There’s of course a native Linux version of Counter-Strike but I don’t believe it’s as well optimized as the Windows version. Call of Duty isn’t playable on Linux due to the anti-cheat system used.

  • Assistive Tech And Video Games | Hackaday

    The basic premise of the circuit is pretty simple. She DIY’d a few contact switches using conductive plates made of cardboard, duct tape, and aluminum foil. The output of the switch is read by analog input pins on an Arduino Leonardo. When the switches are off, the analog input pins are pulled HIGH using 1 MegaOhm resistors. But when the user hits their head on one of the four conductive pads, the switch is engaged, and the analog input pins are shorted to ground.

  • How to install Grapple! by Barji on a Chromebook

    Today we are looking at how to install Grapple! by Barji on a Chromebook. Please follow the video/audio guide as a tutorial where we explain the process step by step and use the commands below. This tutorial will only work on Chromebooks with an Intel or AMD CPU (with Linux Apps Support) and not those with an ARM64 architecture CPU.

5 Best Terminal Based Linux Monitoring Tools

We are going to explore the 5 best terminal based monitoring tools that you can use on your Linux systems to keep you fully aware of their status. Everyone will agree that Linux monitoring tools are required to ensure a healthy Linux infrastructure. Hence, a performance monitoring solution becomes important to observe the health, activities, and capability of your Linux systems. Fortunately, there are many Linux monitoring tools available out there. In this article we are going to talk about 5 lightweight terminal-based and free-to-use tools to monitors servers and desktops running Linux. Read more

‘Video Trimmer’ GTK App Adds Dark Mode, New Encode Option

Among the changes offered in Video Trimmer 0.7.0 is a new checkbox for “accurate trimming with re-encoding” to the output file selection dialog. Whenever you need a frame-perfect result you may want to make use of this option — though it can sometimes result in lower quality, so YMMV. As well as more accurate trimming, the look of the app has been given a once-over. The design of Video Trimmer is said to better match the GNOME Adwaita theme, and the app now sports a dark style/dark mode (and uses this by default, in-keeping with other editing tools). Finally, the app makes finding your exports a touch easier. When video trimming is complete the app shows a(n in-app) notification. As of this release that notification gains a “Show in Files” button. This lets you quickly locate the resulting clip. Read more
