This 5G smartphone comes with Android, Linux - and a keyboard. Back to the future with the Astro Slide

Filed under

London-based Planet Computers is on a mission to reinvent the iconic Psion Series 5 PDA for the smartphone age. Although mobile professionals -- especially those old enough to remember the 1997 Series 5 with affection -- are often open to the idea, the company's previous efforts, the Gemini PDA and Cosmo Communicator, have had their drawbacks.

The Gemini PDA, for example, is a landscape-mode clamshell device that, despite a great keyboard, is difficult to make and take calls on and only has one camera -- a front-facing unit for video calling. The Cosmo Communicator adds a small external touch screen for notifications and some basic functions plus a rear-facing camera, but you still have to open the clamshell to do anything productive.

Astro Slide 5G Transformer Smartphone Comes with a Slide-out Key

  • Astro Slide 5G Transformer Smartphone Comes with a Slide-out Keyboard, MediaTek Dimensity 1000 SoC (Crowdfunding)

    Planet Computers has introduced several smartphones with physical keyboards over the last few years including Gemini PDA and Cosmo Communicator with the later recently received its promised Debian Linux images besides just running Android 9.0.

    The company is now back with the new model. Powered by a MediaTek Dimensity 1000 processor, Astro Slide 5G Transformer supports 5G connectivity and comes with a slide-out keyboard following on the steps of the company’s previous smartphones.

    First of all, the new Pocket Computers device rocks 5G out of the box, thanks to MediaTek’s latest flagship processor, the Dimensity 1000. The Astro Slide also comes with Wi-Fi 6, Bluetooth 5.1, and NFC connectivity.

    Secondly, the full QWERTY keyboard has a novel “RockUp” hinge mechanism. You slide-out the backlit-keyboard entirely from underneath the screen to create a tiny laptop. If you’re into adding physical keyboards to smartphones, this is possibly the best compromise.

    Now, i’m generally wary of mentioning anything that is crowdfunded — and that goes double when it’s hawked on the oasis of overpromise that is IndieGoGo.

    But Planet Computers, the company angling to animate this ode to early 00s technology, have a track record in this area. Not only have they run successful crowdfunding campaigns before, but they’ve also nailed the hard bit: actually shipping products to backers.

    The so-called Astro Slide looks retro but feels modern. Despite the PDA-like appearance, the device is essentially a 5G smartphone that can double as a laptop thanks to a small physical keyboard.

    In terms of hardware, the Astro Slide comes with the essential feature package to let you stay productive on the go. It’s powered by a MediaTek Dimensity 1000 octa-core SoC and obviously comes with a 5G chip specifically optimized for what the parent company says improved signal with reduced power consumption.

  • Astro Slide is a Smartphone/Pocket-Computer that Supports Android and Linux

    Back in CES 2018, Planet Computers took us back to the ’90s with the Planet Gemini PDA. Now, the company is back with another unique device – the Astro Slide 5G Transformer. The “transformer” part in the name represents the pocket-computer form-factor of the device as the screen of the device slides out to reveal a physical backlit keyboard.

  • Astro Slide is a Smartphone/Pocket-Computer that Supports Android and Linux

    Unlike the clamshell design of the Gemini PDA, the Astro Slide uses a slide-out mechanism to reveal the company’s signature keyboard. This keyboard is present in their previous devices like the aforementioned Gemini PDA and the Cosmo Communicator. These keyboards reflect the design of Psion devices from the 1990s and it is not surprising as Planet Computers has some Psion designers working with them.

    Now, the slide-out mechanism is unlike any mechanism out there in the market right now. When the 6.53-inch FHD+ screen slides out horizontally, the hinge forms a tilted stand-like structure to support the screen at an optimal viewing angle. The company is calling the hinge the “Rock-up” design that “transforms” your smartphone into a pocket computer.

    Something to look forward to: Are you tired of modern flagship smartphones that follow a similar design? Nostalgic for the days of BlackBerry PDAs? Then Planet Computers’ Astro Slide could be for you. The device is a 5G phone that runs Android 10, but it also features a sliding physical keyboard and will support Linux in the future.

    According to its Indiegogo campaign page, the Astro Slide is the first 5G phone with a keyboard, and the fastest 5G device announced to date. It uses the company’s RockUp slider hinge to turn the 6.5-inch smartphone into a PDA. The screen flips up so the Astro Slide can be used as a tiny laptop.


    Like its previous devices, the Astro Slide is being crowdfunded. At the time of writing, it’s almost reached $179,000—89 percent of $200,242 target—with 40 days left, so it appears funding won’t be a problem. There are still early bird specials available for $546, while the full retail price will be “anything between $799 and $999.” The devices are expected to be shown off at CES next year, with delivery scheduled for March 2021.

  • Reiser5 File-System Working On New Features Like Data Tiering, Burst Buffers

    Reiser5 was announced back on New Year's Eve with support for local volumes and supporting parallel scaling out and other improvements over the long-in-development but never mainlined Reiser4. While Reiser5 was not met with enthusiasm, Edward Shishkin has continued working on this next-generation file-system and today announced the latest round of improvements. Shishkin announced today with support for dumping peaks of I/O load to a proxy device with Reiser5, "Now you can add a small high-performance block device to your large logical volume composed of relatively slow commodity disks and get an impression that the whole your volume has throughput which is as high, as the one of that "proxy" device!"

  • Steam Beta adds Vulkan shader processing

    Valve has enabled the next step towards making Steam games on Linux run smoother in the latest Steam Beta release. This is something Valve has been working towards for some time now, as the Steam Client has been able to download pre-compiled GPU shaders, which you might have seen when something pops up in your Steam Downloads with an OpenGL and Vulkan icon below. [...] It doesn't just do it for installed games, it will do it as you're downloading them too, so by the time you've finished downloading it might even be all ready.

  • Adaptive-Sync/VRR Seeing Port To xf86-video-modesetting Driver

    Currently if wanting to use Adaptive-Sync/FreeSync variable refresh rate support of the AMDGPU DRM kernel driver you need to be using the xf86-video-amdgpu X.Org driver for proper handling as well, but a port of the DDX bits to the generic xf86-video-modesetting driver is in the works. This is still obviously contingent upon the DRM kernel-side support in the AMDGPU DC code, but for those using this generic DDX driver, it at least allows the Adaptive-Sync/VRR handling there.

Plasma Mobile update: April-May 2020

It’s been a while since the last status update on Plasma Mobile, so let’s take a look at what happened since then.

  • What is ESP32 and Why Is It Best for IoT Projects?

    ESP32 is a low-powered, low-cost microcontroller (MCU) board, with both Wi-Fi and Bluetooth built in, and is based on a dual-core processor mechanism. The first one is a powerful processor, such as a Xtensa LX6 (~240 MHz) with 512 KiB memory and the second an ultra-low coprocessor (ULP) with only 8 KiB memory designed to run when ESP32 is in deep-sleep mode. Other components include around 48 I/O pins (variable); an array of peripheral interfaces including temperature, hall effect, and capacitive touch sensors; and an 8-centimeter LCD panel, prominently visible here in an ESP32-WROVER board by Espressif Systems. [...] In fact, it runs on FreeRTOS, a leading operating system supported by Arduino. A big advantage of ESP32 is that it is readily supported by Arduino IDE as a “shield” which can be accessed from Board Manager. One can easily use functions from the FreeRTOS libraries when coding for the ESP32 within the Arduino IDE. Considering the scale of ESP32 applications which could be tiny, coin cell devices, it is better to use a predictable memory OS such as FreeRTOS rather than have its own complete OS, which is supported by Raspberry Pi, for example.

  • Kiwi TCMS is partnering up with Pionir

    We are happy to announce that Kiwi TCMS is going to partner with Pionir on the development of open source hardware for testers! Pionir is a free school focused on creating a new generation of digital leaders, an exponential culture and solving challenges using technology. They are located in Kikinda, Serbia. [...] Pionir will be developing hardware black boxes for teaching exploratory testing in cooperation with Kiwi TCMS. We have dedicated €2000 from our bounty program for students of the free school towards completing this project.

    The goal of the project is to produce at least 3 boxes and reference designs that will serve as a didactic tool for teaching, but also be free and open hardware, and as such, available to everyone to build from source. This project will be trusted to the students of the free school who will get opportunity to take part in the challenging process of building a digital appliance, from designing the machine logic, to develop and prototype hardware.

    The project includes designing, assembling, programming, documenting and delivering this hardware to us! Everything is expected to be open source: list of components, assembly instructions, 3D design files, source code, documentation and instructions! Our goal is that this will be relatively cheap and easy to build so everyone else can build their own boxes. During the next several months there will be new repositories created under to host the various boxes.

  • How does the Glean SDK send gzipped pings

    Within the Glean SDK, the glean-core Rust component does not provide any specific implementation to perform the upload of pings. This means that either the language bindings (e.g. Glean APIs for Android in Kotlin) or the product itself (e.g. Fenix) have to provide a way to transport data from the client to the telemetry endpoint. Before our recent changes (by Beatriz Rizental and Jan-Erik) to the ping upload system, the language bindings needed to understand the format with which pings were persisted to disk in order to read and finally upload them. This is not the case anymore: glean-core will provide language bindings with the headers and the data (ping payload!) of the request they need to upload. The new upload API empowers the SDK to provide a single place in which to compress the payload to be uploaded: glean-core, right before serving upload requests to the language bindings.
