Custom PC, Issue 219

Custom PC Issue 219In this month’s Custom PC I take a look at the Airxed IRX Smart Home Hub, revisit the Kobol Helios64 open-spec network attached storage (NAS) appliance, and read through Wired’s pocket-size guide to quantum computing by Amit Katwala.

First, the hub. Looking for all the world like a fat gloss-finish hockey puck, the IRX is effectively a cross between a programmable remote and an environmental monitor. Inside the housing is an array of through-hole infrared LEDs, arranged in a hedgehog-like pattern. Trigger an IR signal using the companion app, and they all fire at once offering room-filling coverage – not like the bad old days of taping an IR blaster to a sensor to get the positioning just right.

Combine that functionality with a temperature and humidity sensor, all drive by an Espressif ESP-12S ESP8266-based microcontroller, and you’ve an interesting device. Sadly, despite an attractive price there are a fair few downsides to the design – and I was entirely unable to find my Yahama AV receiver in the list of infrared gadgets it could control.

I originally reviewed the Helios64, meanwhile, back in Issue 211. At the time my conclusion was that, despite some glaring design flaws and software issues, it was a tempting buy – a conclusion I now revisit on the news that Kobol is closing up shop and the bug-fixed second revision will no longer be released. Couple that with the discovery of yet more hardware failures and serious concerns about the Armbian project on which the device runs, and it’s no longer recommended – even if you could pick one up cheaply on the second-hand market.

Finally, Quantum Computing is the first in a series of compact primers covering a range of topics selected by Wired Magazine. Written by Amit Katwala, it’s a broad though shallow romp through the latest in the field of quantum computing technology – looking at everything from its impact on cryptography to commercial quantum systems. For the curious, it’s a great introduction to the topic – but most will be left wanting something more when they reach the end.

PC Pro, Issue 298

PC Pro Issue 298The big news of the last few weeks has, of course, been the launch of the Raspberry Pi 4 single-board computer – covered in considerable detail in my benchmark piece over on Medium. To support its in-house review coverage, PC Pro Magazine commissioned me to come up with project ideas that take full advantage of the Raspberry Pi 4’s new capabilities.

The first of a new family of Raspberry Pi products designed to do away with some of the biggest criticisms levelled at earlier models, the Raspberry Pi 4 includes a significantly more powerful processor, improved graphics capabilities, dual-4K video output and hardware H.265 4K video decoding, up to 4GB of RAM, true gigabit Ethernet networking, and two USB 3.0 ports sharing a high-speed PCI Express link back to the Broadcom BCM2711B0 system-on-chip (SoC) at the board’s heart.

My feature covers how these new capabilities can be used in a variety of real-world use-cases, from acting as a desktop replacement for lightweight browsing and productivity use to a low-power 4K-capable home cinema system. The new USB 3.0 ports are perfectly suited to turning a couple of external hard drives into a low-cost network-attached storage (NAS) system, while the improved graphics make gaming more tempting.

There’s even something for the enterprise crowd to sink its teeth into: the dual display capabilities mean that the Raspberry Pi 4 is perfect for digital signage, Citrix support on day one turns it into a dual-screen thin client, and the more powerful networking can be combined with a USB 3.0 Ethernet adapter to create an energy-efficient router, firewall, or other network appliance.

For the full low-down on what the Raspberry Pi 4’s new features could do for you, pick up the latest PC Pro from your nearest supermarket, newsagent, or digitally via Pocketmags or similar services.

The MagPi, Issue 54

The MagPi Issue 54This month’s The MagPi Magazine, the official publication of the Raspberry Pi community, features my review of an impressive compact network-attached storage (NAS) device: the Nextcloud Box.

Built around the PiDrive storage system from Western Digital Labs and featuring software from the open-source Nextcloud project – itself born from a fork of the Owncloud project – the Nextcloud Box does exactly what it says on the tin: it’s a box which runs Nextcloud.

More accurately, it’s a box that can run Nextcloud. Out of the box, there’s a key piece missing: the packaging reveals a two-part plastic chassis with clever magnetic clasp, a smart split power and data cable, a power supply, a 1TB Western Digital 2.5″ hard drive, and a micro-SD card with the Nextcloud software already loaded onto an Ubuntu Core installation. What you don’t get is a Raspberry Pi: the brains need to be supplied separately, with only the Raspberry Pi 2 supported at the time of writing.

Once you’ve affixed your Pi in place with the bundled Torx screwdriver and screws, you can begin the installation process – which is as simple as putting the micro-SD card in and connecting power. Over the course of a few minutes the operating system is copied to the 1TB hard drive, and then the system reboots ready for configuration.

Nextcloud is, I have to say, incredibly impressive software. While there’s some way to go in certain aspects of usability – in particular setting the NAS up for access from outside your home network requires a bit of fiddling at the command line, registration of a domain name, and manual port forwarding on your router or gateway – the UI and general functionality are both polished to a high standard.

For my full opinion on the device, though, you’ll have to read the review – and you can do so for free by downloading the Creative Commons licensed DRM-free PDF at the official MagPi website, or by picking up a print copy from your nearest supermarket or newsagent.

Custom PC, Issue 161

Custom PC Issue 161In this latest issue of Dennis Publishing’s Custom PC Magazine you’ll find – to no great surprise – my long-running five-page Hobby Tech column, covering the handy thermoplastic FORMcard, the Raspberry Pi powered Nextcloud Box, and Zachtronics’ Shenzhen I/O.

Looking at Shenzhen I/O first: it’s rare that I’ll write a game review as part of Hobby Tech, but Zachtronics’ output is a typical exception. The last I covered was the company’s excellent eight-bit minicomputer ‘simulator’ TIS-100, and Shenzhen I/O builds on that premise with a new near-future theme. The player is placed in the role of a newly-hired engineer at a Chinese electronics concern and given the task of building increasingly complex hardware from simple components using a drag-and-drop interface and a simple TIS-100-like instruction set.

As good as the game itself is – and it’s absolutely fantastic – it’s the manual that really caught my attention. Like the Infocom feelies of old, the document is written entirely in-universe and acts as a series of emails, manual extracts, data sheets, and reference material for the hardware and projects you’ll be tackling through the game. If TIS-100 whet your whistle, you won’t be disappointed with Shenzhen I/O.

The Nextcloud Box, meanwhile, is something a little more professional. Designed around the Western Digital Labs PiDrive product, it offers a simple means to build a single-drive low-power 1TB network attached storage (NAS) device running Nextcloud’s open-source software on top of the Ubuntu Snappy Core operating system.

My review of the Nextcloud Box goes into great detail about its features and capabilities, but there are two things that struck me during the review process and are worth highlighting here. The first is that the WD Labs’ box, emblazoned with Nextcloud branding, really needs a rethink: the cables go through very sharp bends, and those using cheaper cables may find they don’t last very long at all. The other is that getting set up for local access was an absolute breeze, without even the need to connect a monitor to the device – something other Pi-powered project creators could do with copying.

Finally, the FORMcard review. I’ve long been a fan of Sugru, a mouldable silicone putty which hardens into rubber overnight, and when I was contacted to see if I would be interested in giving rival FORMcard a try I jumped at the chance. Created by Peter Marigold and crowdfunded into production, FORMcard is a starch-based bioplastic which softens with the application of heat. Simply take one of the credit card footprint plastic sheets, dunk it in hot water for a minute, then mould it to your hearts desire. Unlike Sugru, it hardens in minutes and is fully reusable – assuming you can remove it from whatever surface you smeared it over – but it’s, for obvious reasons, not the material to use if you’re patching something that gets hot.

For my full opinions on all three items, plus the usual array of interesting things written by people who aren’t me, you can pick up the latest Custom PC Magazine from your nearest newsagent, supermarket, or from the comfort of right where you are now via Zinio and similar digital distribution platforms.

Linux User & Developer, Issue 172

Linux User & Developer Issue 172Readers of this latest issue of Imagine Publishing’s Linux User & Developer will find my review of the surprisingly capable Nextcloud Box, a bare-bones network attached storage (NAS) system based around a Raspberry Pi 2.

Provided as a press sample by Nextcloud, the company split from the Owncloud project, the Nextcloud Box is at its heart a rebadged – though, oddly, cheaper – Western Digital Labs PiDrive. Inside the box you find the black plastic housing, a 1TB USB hard drive, a clever splitter cable for power and data, and the screws you need to mount your own Raspberry Pi. You also get a small 4GB micro-SD card, which serves as the bootstrap device: on first run, the operating system is copied from this micro-SD to the 1TB hard drive.

It’s the contents of the micro-SD card that makes the Nextcloud Box distinct from the PiDrive: it contains a copy of Ubuntu Snappy Core and a preinstalled Snap of the Nextcloud NAS software. Administered almost entirely from a web interface, Nextcloud proved to a powerful NAS package with everything from encrypted storage and remote access to centralised calendar and contact facilities – and with additional functionality available through a built-in ‘app store’ feature.

If you’re interested to read the full review Linux User & Developer Issue 172 is on shelves now at supermarkets and newsagents throughout the land, or can be grabbed in digital format from Zinio and similar services.

Custom PC, Issue 106

Custom PC, Issue 106This month’s Custom PC Magazine includes my usual Mobile Tech Watch column along with a central feature: a hands-on guide to the Raspberry Pi.

First, the column. In a slight departure from the norm, I took a look at whether transparent, foldable electronics – as seen in films like Iron Man 2 and Ultraviolet (yes, I watched – and enjoyed – Ultravoilet. Don’t judge me) are in any way possible using current technologies.

The answer came as a surprise: yes, yes they are. Between Samsung’s transparent OLED displays, LG’s flexible electrophoretic screens, Rice University’s transparent and flexible electronics and Yuan Yang’s equally bendy see-through battery technology, it’s well within reach if a company has the R&D funds to spare.

The feature – the first full-length feature I’ve done for Custom PC in a long while – sits in the middle of the mag and holds the coveted “Plus” spot on the cover. Unlike my previous Raspberry Pi pieces, which have been reviews, this is a hands-on how-to tutorial starting off with an overview of what’s on the board and branching out into step-by-step guides on setting it up, turning it into a network attached storage (NAS) device, a home theatre PC, and how to address the general-purpose IO (GPIO) pins through Python. It also includes a section on overclocking, albeit with the required “it’s not a good idea to do this” warning in pride of place.

Sadly, there are a couple of hiccoughs with the piece, introduced during the layout and editing stage. It’s nothing major, although a couple of the commands won’t run correctly without modification. Custom PC’s editor, Ben Hardwidge, has promised that corrections will be published in the next issue and on the Custom PC Facebook page. Meanwhile, here are my original (correct) listings for each broken step:
