3D Printed Smart Glasses Put Linux In Your Face

Filed under
Linux
Gadgets

Unimpressed by DIY wearables powered by dinky microcontrollers, [Teemu Laurila] has been working on a 3D printed head-mounted computer that puts a full-fledged Linux desktop in your field of view. It might not be as slim and ergonomic as Google Glass, but it more than makes up for it in terms of raw potential.

Featuring an overclocked Raspberry Pi Zero W, a ST7789VW 240×240 IPS display running at 60 Hz, and a front-mounted camera, the wearable makes a great low-cost platform for augmented reality experiments. [Teemu] has already put together an impressive hand tracking demonstration that can pick out the position of all ten fingers in near real-time. The processing has to be done on his desktop computer as the Zero isn’t quite up to the task, but as you can see in the video below, the whole thing works pretty well.

Development of the PinePhone keyboard has just about wrapped up, and this accessory for the $150 Linux-friendly phone should be available soon for around $50.

The hardware has been finalized and sent out to a number of folks for testing, and megi has created open source firmware for the keyboard that will be loaded at the factory before keyboards are shipped to customers. But if you want to flash your own firmware, you can do that… it just requires opening up the case and performing a little surgery.

How to use PinePhone as a mobile hotspot

Filed under
Gadgets
HowTos

I’ve recently started using my Android phone as a mobile hotspot with mixed results so instead, I’ve switched to using PinePhone as a hotspot with Manjaro Arm Linux with Plasma Mobile instead, and performance seems much more stable now.

Early this year, I received Pinephone with PostMarketOS beta, and after playing with it a bit I did not do much with it so far. But in recent times, I’ve been staying in various places without WiFi, so I purchased a lost cost SIM card with a one-year cellular data plan to be able to work from any location using my Android 10 smartphone (Huawei Y9 Prime 2019) as a mobile hotspot. It works most of the time, but sometimes I have massive packet loss, and the only way to recover is to turn off and on the hotspot, and in some cases even reboot the phone. Playing with settings on the phone or my laptop did not help, so instead, I decided to make use of my PinePhone and use it as a mobile hotspot to see if things improved.

Sxmo 1.5.0 released with networking, screen lock, and UI improvements

Filed under
OS
Gadgets

The latest version of Sxmo adds a few new features including support for configuring a WiFi hotspot from your phone’s Network Menu and support for a proximity lock that automatically locks or unlocks the display based on proximity (so the screen doesn’t come on when your phone is in your pocket, for example).

Sxmo 1.5.0 also brings a number of performance and user interface tweaks and some under-the-hood changes. But overall, Sxmo continues to be a simple, speedy user interface for mobile Linux devices. In fact, it’s so well optimized that it can make even a low-end smartphone like the PinePhone feel fast.

WayDroid lets you run Android apps on Linux phones (with smoother performance than Anbox)

Filed under
Gadgets

Smartphones are basically pocket-sized computers running mobile-friendly operating systems. And folks who want to run a free and open source GNU/Linux distribution on their phones get the advantages of a hackable, customizable OS that can run desktop Linux applications as well as mobile apps.

But the selection of mobile-optimized Linux apps is still rather small, which is why some folks have been using tools like Anbox to run Android applications on Linux phones. But now there’s a new work-in-progress alternative to Anbox called WayDroid which offers smoother performance on supported devices.

A clunky (but useable) method for recording video on a PinePhone

Filed under
OS
Gadgets

Most smartphones ship with software capable of taking advantage of all the device’s hardware. But the PinePhone isn’t most smartphones. It’s designed to be an open platform for developers and when it first began shipping there was only some very basic software available.

Among other things, there was no working camera app. Now there is. And up until recently there had also been no good method for recording video on a PinePhone. But now redditor UJC_theguy has come up with a method for recording 720p video at 30 frames per second.

Pine64's $30 Linux Smartwatch Launches

Filed under
Linux
Gadgets

Back in 2019, Pine64 announced that it was working on a $25 Linux smartwatch. It turns out $25 was a little optimistic because, as OMG! Ubuntu! reports, the PineTime has now launched carrying a $29.99 price tag. I think we can all forgive Pine64 for charging an extra $5, and the current Community launch price is only $26.99.

Keeping in mind how little this smartwatch costs, you're getting a device that weights 38 grams and is made from a mix of zinc alloy and plastic. The display is a 1.3-inch IPS touch screen panel with a 240-by-240 pixel resolution and 65,000 colors. The internal memory consists of 64KB of RAM, 512KB of Flash system storage, and 4MB of additional flash storage. The watch is powered by a 64MHz ARM Cortex-M4F as part of the Nordic Semiconductor nRF52832 SoC.

  • Oracle v. Google: What the verdict means for open source | InfoWorld

    The decade-long legal battle between two of the world’s largest tech companies has finally come to an end. The result was a victory for the open-source software community. In case you need a refresher on the Oracle v. Google case, Oracle sued Google in 2010 for copyright infringement on Google’s use of Oracle’s Java API in its Android smartphone operating system. The District Court ruled in favor of Google, but that decision was later reversed on appeal. The case ultimately landed in the U.S. Supreme Court, which ruled six to two in Google’s favor this April.

    Aggrieved MacBook owners in two separate lawsuits claim Apple's latest laptops with its M1 chips have defective screens that break easily and malfunction. The complaints, both filed on Wednesday in a federal district court in San Jose, California, are each seeking class certification in the hope that the law firms involved will get a judicial blessing to represent the presumed large group of affected customers and, if victorious, to share any settlement. Each of the filings contends Apple's 2020-2021 MacBook line – consisting of the M1-based MacBook Air and M1-based 13" MacBook Pro – have screens that frequently fail. They say Apple knew about the alleged defect or should have known, based on its own extensive internal testing, reports from technicians, and feedback from customers.
