PC & Tech Authority, Issue 232

PC & Tech Authority Issue 232This month’s PC & Tech Authority includes a reprint of a review I originally wrote for PC Pro Magazine, in which I turn my eye to the Kano Computer Kit, the latest bundle of parts from the eponymous London-based education-centric company – and here’s what I had to say at the time of the original review.

The original Kano kit proved a smash hit when it landed on crowdfunding site Kickstarter back in 2013, raising more than $1.5 million to produce what it claimed was a computer you built yourself. Its launch was marred, however, by a modicum of controversy: what Kano had made was not a computer, but rather a selection of accessories – case, speaker, keyboard, and a customised GNU/Linux operating system – which it bundled with the already-existing Raspberry Pi, turning it from the “computer you build” to the “computer you put in a case and plug a USB dongle into.”

The crowdfunding success was followed by efforts to set up a sustainable business, and the Kano kits are now available globally direct from Kano and through resellers. For review I received the two latest revisions, the Kano Computer Kit and Kano Display Kit, bundled together as the Kano Complete Computer Kit.

The Computer Kit takes a Raspberry Pi 3 then bundles it with the Debian-based Kano OS software, a case, GPIO-powered speaker, combined wireless keyboard and trackpad in fetching orange, and the Kano ‘story book’ manual. The Display Kit adds a non-touch display panel, a custom stand the Kano case can hook into, and a smart split power cable that allows the display and Raspberry Pi to be driven from a single socket.

The hardware, sadly, proved disappointing for the cost. At an RRP of £299, the kit isn’t exactly value for money: a Raspberry Pi 3, speaker, wireless keyboard and trackpad, official touchscreen display, power supply, micro-SD card, and a decent book could be had for around half the cost and provide roughly equal educational value – if, that is, you ignore the software.

Kano OS is, to put it simply, fantastic. For full details you’ll have to read my review, but it’s fair to say I was in love with the platform from the moment I powered the Kano kit on. Interestingly, though, you don’t need a Kano kit to use Kano OS: the Debian-based Linux distribution is available to download completely free of charge from Kano’s developer site, and can be used on any existing Raspberry Pi.

Custom PC, Issue 163

Custom PC Issue 163My work for Hobby Tech this month involved rather more soldering than is usual, in order to assemble the parts required for reviews of the Boldport Club’s Ligemdio and Touchy kits and the Dark Control Raspberry Pi motor control boards – though, at least, the final review of the freshly-launched Debian+Pixel Linux distribution was free of fumes.

First, the Boldport Club. I’ve reviewed one of Saar Drimer’s impressively artistic circuit kits before, back in November 2015, but where you used to have to camp out on the Boldport website to pick up the latest small-production-run kit there’s a new option: monthly subscription. Members of the Boldport Club get a series of parcels, typically but not always including a kit featuring a Saar-designed printed circuit board but almost always being aimed more at the experienced engineer than the absolute beginner.

For a flavour of what Boldport Club members can expect, Saar sent over two kits: the Touchy, a touch-sensitive microcontroller dedicated to the memory of maker Oliver Coles, and the Ligemdio, a handy-dandy USB-powered LED tester. The latter proved far simpler to build than the former: anyone used to beginner through-hole kits would undeniably find the surface mount components on the Touchy a challenge, but therein lies its attraction.

The soldering on the Dark Control boards, by contrast, was considerably less tricky. Created by the Dark Water Foundation and funded via Kickstarter, the Dark Control boards – one for DC motors and the other for ESC motors – are impressive beasts. Designed to mimic the footprint of the diminutive Raspberry Pi Zero, the boards include the ability to run a minimum of six independent motors, include room for a nine-degree sensor add-on, and can be linked to remote control hardware for network-free control of everything from submarines to aerial drones.

Finally, Debian+Pixel is Raspbian for the masses. Like Raspbian, Debian+Pixel is built on top of Debian Linux; like Raspbian, Debian+Pixel uses the Pixel desktop environment; like Raspbian, Debian+Pixel includes a selection of educational software chosen by the Raspberry Pi community. Unlike Raspbian, though, Debian+Pixel runs on almost any x86 PC – meaning you don’t need a Raspberry Pi.

The software is, as you’d expect from a distribution based on one of the oldest Linux variants around, stable. The Pixel interface looks the same whether you’re running on a Pi or a traditional PC, and only the speed at which programs open and run gives it away. Sadly, there are one or two omissions largely as a result of licensing agreements: the handy Wolfram Alpha application is nowhere to be found, as is the extremely buggy Minecraft Pi Edition that saw one release back in 2013 before being abandoned by the now Microsoft-owned Mojang.

For the full run-down of all these shiny things, plus a whole bunch of other stuff written by people who aren’t me, you can pick up the latest Custom PC magazine in your nearest supermarket, newsagent, or electronically via Zinio and similar digital distribution platforms.

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.

Hello World, Issue 1

Hello World Issue 1The Raspberry Pi Foundation has launched a new magazine, Hello World, and I’m thrilled to have contributed photography to its launch issue – the first, hopefully, of many to come.

Designed to sit alongside The MagPi rather than replace it, the Foundation’s second magazine takes aim at a different audience: where The MagPi is for the Raspberry Pi community as a whole, Hello World focuses purely on computing education – and not exclusively Raspberry Pi-related topics, either, with hackspaces and 3D modelling software among the subjects covered in the launch issue.

While I’m primarily a technical writer and journalist, I’m also a photographer. Whether it’s events I’ve attended or product photography, whatever I take I release publicly under a permissive Creative Commons Attribution Share-Alike licence which allows anybody – including commercial businesses – to take the images and use them as they see fit, so long as I am identified as the original creator and any derivative works are released under the same licence.

It’s always a pleasure to see my photos cropping up in new places, and I’m proud as punch that includes Hello World. The full issue is available to download now as a free PDF from the official website, while you can see more of my photography – and download full-resolution images to use yourself – on my Flickr page.

PC Pro, Issue 269

PC Pro Issue 269In this month’s PC Pro I turn my eye to the Kano Computer Kit, the latest bundle of parts from the eponymous London-based education-centric company – and come away with distinctly mixed feelings.

The original Kano kit proved a smash hit when it landed on crowdfunding site Kickstarter back in 2013, raising more than $1.5 million to produce what it claimed was a computer you built yourself. Its launch was marred, however, by a modicum of controversy: what Kano had made was not a computer, but rather a selection of accessories – case, speaker, keyboard, and a customised GNU/Linux operating system – which it bundled with the already-existing Raspberry Pi, turning it from the “computer you build” to the “computer you put in a case and plug a USB dongle into.”

Custom PC, Issue 162

Custom PC Issue 162In Hobby Tech this month I take a look at the new Raspberry Pi-based Kano Complete Computer Kit, the eight-bit Arduboy handheld games console, and the undeniably impressive Mirobot educational robot.

To look at the Mirobot first, it’s no secret that I was eager to put it through its paces. Turtle-style robots, which roll around the floor drawing pictures, were immensely popular in the 80s, and the Mirobot looks to bring the technology bang up to date. Entirely open source, from the circuits to the software, the Mirobot is based around two microcontrollers: an Arduino, which handles the actual robotics, and an ESP8266, which provides Wi-Fi connectivity and handles the user interface and ever-so-smart over-the-air (OTA) flashing capabilities.

The Mirobot screams smart from the moment you open the package: its body is made from laser-cut MDF, and the panels form the packaging itself. Everything is put together without tools, and getting up and running requires no software installation – just a device with a modern browser. Multiple programming languages are available, and an API for those who want to roll their own software. In short, I’m a Mirobot fan – and I’d heartily recommend picking one up if you’ve an interest in open-source robotics or programming for education.

The Kano Complete Computer Kit, on the other hand, comes at education from a very different perspective. Billed somewhat disingenuously as a computer you ‘build,’ the kit is at its heart a speaker and case for a bundle Raspberry Pi alongside a customised operating system which is the project’s true selling point.

The Kano kits have been around for a while now, but the Complete Computer Kit as reviewed is new: the computer side has been refreshed to include the latest Raspberry Pi 3, while the bundle also includes a high-quality but non-touch display which accepts the Kano-cased Pi in its rear. It’s a lovely kit, and the software – which you can download for free and run on your own Raspberry Pi – is phenomenal, but its cost definitely lets it down: at £299 RRP it’s massively overpriced.

Finally, the Arduboy. Crowdfunded and hit by numerous delays on its way to market, the Arduboy is an extremely smart little handheld console based around an Arduino-compatible ATmega microprocessor. Games are written in the Arduino IDE then flashed onto the credit card sized device via USB, and play out on a teeny-tiny little single-colour OLED panel which is sadly prone to bad banding.

The Arduboy is a lovely device, but it’s not the first design I’ve seen – and nor is it my favourite. The Gamebuino, reviewed back in Issue 134, still sits at the top for a number of reasons: it’s cheaper, it has better battery life, and it has a clever system for loading games from a bundled micro-SD card. The Arduboy, by contrast, is slimmer, has a clearer display, but can only carry a single game at a time. When you want to switch games, you’ll need a computer with the Arduino IDE – and that’s a major drawback in a portable gaming device.

All this can be yours, alongside the usual raft of interesting things written by people who aren’t me, at your nearest newsagent, supermarket, or from the comfort of wherever you are now via Zinio and similar digital distribution services.

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.

The MagPi, Issue 52

The MagPi Issue 52It’s a Christmas themed issue for The MagPi this month but you wouldn’t know it to look at my review of the Dremel 3000 Four-Star Kit, a new bundle packing the eponymous company’s most popular rotary tool with a range of accessories in a disappointingly cheap plastic toolbox.

That the toolbox – and bundled ‘chess set,’ which is actually just a chequerboard on the reverse of the packaging and some cardboard counters – is so poorly designed was an undeniable letdown as I unboxed the Dremel 3000 kit. Thankfully, things soon looked up: it’s been a few decades since I bought a rotary tool, and it seems things have improved immensely in that time.

My favourite of the bundled accessories – which includes a flexi-shaft add-on, cutting accessories, milling bits, polishing bits, and basically everything you might need to do a wide range of tool-suitable jobs – was the EZ-SpeedClic system. A replacement for the old screw-and-mandrel method of securing grinding and cutting discs into the tool, EZ-SpeedClic requires nothing more than a push and a twist to secure the specially-reinforced discs into place. A shame, then, that so few SpeedClic discs were included, with the majority in the kit being of the old-fashioned screw-in variety.

Still, the review was a fun opportunity to get myself back up to speed on the latest developments in Dremel’s design, and if you want to know my final opinion on the kit you can read the whole review – the whole magazine, in fact – for free by downloading the Creative Commons licensed issue from the official website.

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 160

Custom PC Issue 160This month’s edition of Custom PC includes, as usual, my five-page Hobby Tech column covering the Dremel 3000 Four-Star Kit, the CHIP and PocketCHIP microcomputers, and the conclusion of the Arduino-versus-Arduino saga – in a happy ending, I’m thrilled to say.

Rotary tools like the Dremel 3000 are one of those things you don’t think you need until you get one. It’s been a long time since I played with a proper Dremel-branded example, and this month’s review was a fantastic excuse to get myself up to speed with the changes the platform has enjoyed.

Ignoring the poor-quality ‘toolbox’ the kit comes in, I was particularly excited by the EZ-SpeedClic system. My original Dremel-like tool – a Black & Decker Wizard – had long been abandoned after frustrations with the tiny screw which attaches cut-off and grinding discs to the equally tiny mandrel. EZ-SpeedClic does away with that: the discs’ reinforced centres just twist and snap onto a clever sprung holder. Coupled with some shiny new accessories, I could see why people might want to upgrade from older or rival models.

The CHIP and PocketCHIP, meanwhile, came as more of a surprise. Like many, I was dismissive of NextThingCo’s inaugural crowdfunding campaign; the idea of a $9 fully-functional microcomputer when the Raspberry Pi had only just got the things down below $30 seemed laughable, and many in the industry suggested it was an outright fraud or at least a loss-leader to be offset by future sales at a higher price.

Proving the critics wrong, though, NextThingCo launched the $9 CHIP – albeit requiring add-on cables and adaptors to get a picture out of the thing – and followed it up with the PocketCHIP, an open hardware proof-of-concept which turns the CHIP into a surprisingly capable hand-held computer straight out of the early 90s.

Finally, regular readers will remember my coverage of the legal battle between Arduino.cc and Arduino.org which had given birth to the Genuino trademark, and the follow-up piece in Issue 159 covering Pimoroni’s decision to drop all Arduino and Genuino products as a result. The final page of this month’s column is, hopefully, the last I will have to write on that particular topic: the two companies have agreed to settle their disputes, join forces, and work together under a single Arduino brand – meaning, of course, that Genuino-branded products are likely to vanish from the market in due course.

All this, and stuff written by people other than myself, can be found at your local newsagent, supermarket, or on the electronic shelf substitutes of services such as Zinio.
