Devices With Linux and Other Free Systems

• Embedded Linux development on Ubuntu – Part I | Ubuntu

  Throughout this series, we will discuss the key challenges of traditional software distribution mechanisms for embedded Linux devices. We will understand why legacy development and update approaches do not suit the Internet-of-Things (IoT) world and assess how Ubuntu simplifies and secures embedded Linux development. Although you don’t need prerequisite knowledge to follow this series, we recommend you have a basic understanding of the role played by Linux in the embedded portion of the compute spectrum. If you are new to the space and just getting started from scratch, get an intro to embedded Linux or delve into the official guide to Linux for embedded applications.

• DepthVista combines RGB and 3D Time of Flight depth cameras

  Last week, e-con Systems launched the DepthVista camera which contains both an RGB and a Time of Flight (ToF) depth camera with a range of up to six meters. According to the company, the DepthVista can measure the distance from itself to a target object with an accuracy of < 1% depending on environmental conditions. The RGB camera integrated on the DepthVista is the AR0234CS CMOS digital image sensor (1/2.6-inch) from onsemi which is optimized for capturing high definition images for fast-moving objects. On the other hand, the 3D camera implemented seems to be the See3CAM_2TOF_5CUG from e-con itself.

• Rockchip RK3588 CPU module exposes more I/Os through four board-to-board connectors - CNX Software

  We’ve already seen several Rockchip RK3588 modules with Firefly Core-3588J, Turing RK1, and Banana Pi RK3588_CV1, all with an edge connector to insertion into the carrier board. Rongpin RD-RK3588 system-on-module is a little different with four board-to-board connectors that enable a slightly more compact design, and should expose more I/Os than say a 314-pin MXM edge connector.

• Meet Bittle, an Advanced Open-Source Robot Dog by Petoi - The DIY Life

  This is Bittle, a ready-to-run advanced open-source robot dog by Petoi that is based on the OpenCat robotic pet framework. If you’ve ever wanted to explore building your own robotic quadruped, but have felt overwhelmed by the amount of information and options available or have been at a loss with where to start, then Bittle is the perfect product for you. So in this review, we’ll take a look at what Bittle is, how it works and what it can be used for.

• Remote indoor air quality monitoring with the Arduino Nicla Sense ME and Nano 33 IoT | Arduino Blog

  Most air quality-sensing devices integrate their sensors into the same enclosure as the display, which can make getting an accurate reading tough since the viewer is directly next to the unit and could potentially skew the values. This is why one element14 community member Enrique Albertos created his own portable air quality monitor that separates the sensing module from the screen. His system uses one Nicla Sense ME to gather air quality information about the surrounding environment with its onboard BME688 gas sensor. It is highly capable too, as it can quantify pressure, humidity, temperature, VOCs, VSCs, and various other harmful gases such as carbon monoxide. From here, the Nicla Sense ME sends its data over Bluetooth to an awaiting Nano 33 IoT board. The Nano is connected to a 1.8” TFT screen, which shows several pages of information that are cycled through by pressing one of the buttons at the bottom of the device.

Games: Valve and ScummVM

• Valve Gets ‘Right To Repair/Mod’ Right With The Steam Deck

  We’ve talked a great deal about the public’s right to repair the tech they own and how right to repair has finally started to shift in favor of the consumer as of late. In tech in general, and specifically in the video gaming hardware space, manufacturers have long fought to make it impossible for the public to repair their own gear. Or mod that gear, as well. And this isn’t just a Nintendo thing, though that’s likely the first name that leapt into your mind. Sony, Microsoft, ASUS, and HTC all lobbied heavily to prevent DIY repairs or mods.

• Steam Deck replacement parts now in stock at iFixit

  Those of you lucky enough to own a Valve Steam Deck may be pleased to know that if you should damage your handheld console in anyway, you can now purchase Steam Deck replacement parts directly from iFixit. Everything is available from case to motherboard and instructions on how to fit and replace parts are provided by the engineers at iFixit providing a difficulty score for each component together with individual steps and the time you will need to set aside to replace the damaged component.

• We're finally ready to ESCape from F5

  After an extended period of time, we're finally ready to announce for testing the game Chewy: ESC From F5. This quirky game features the protagonist Chewy as he tries to outwit the evil Borks.. escaping from their high security zone, F5, will just be the start of his adventure. So if any of you have the game and are willing to test it out, we'll welcome any feedback. You will need a daily development build. As always, please submit the bug reports to our issue tracker. Please note that the ScummVM version does have one obvious limitation, though.. the music used by the game is in a custom format we've been unable to properly support yet. So only sound effects and speech currently work.
