PC Pro, Issue 297

PC Pro Issue 297The Labs Test in this month’s PC Pro is something of a bumper one: I ran a whopping 14 miniature PCs, from a cleverly cased Raspberry Pi up to a behemoth of a system squeezing in an Nvidia GeForce RTX 2080, through a gamut of tests including size and weight, power draw, productivity and gaming benchmarks to see which would come out on top.

The work of a solid few weeks, the Labs saw system after system bouncing onto and off the test bench. As well as requiring the actual testing, all photography was carried out in-house – with thanks to my wife, who served as a hand model for the article’s hero shot – with each system photographed from all angles and internally, plus a smart isometric view in which the scale is maintained so the reader can easily compare the relative sizes of each machine on test. Given that the feature is about miniature PCs, such easy at-a-glance comparison is key to knowing which machine meets the readers’ personal requirements.

A Labs Test like this wouldn’t be possible without the cooperation of a range of companies, of course, and I’d like to thank the suppliers of machines for the test: ASRock, Asus, Intel, Mini-ITX.com, Lenovo, QuietPC, Raspberry Pi, and Shuttle. Additional thanks go to Intel, Nvidia, and Overclockers UK, who provided components required to build up the bare-bones systems on test.

As is traditional for a PC Pro Labs Test, the content is split between reviews – four 700-word focus reviews and ten 350-word supplementary reviews – and features, including an interview with Intel’s Ed Barkhuysen on the company’s modular vision for the future of computing, a buyer’s guide covering things to consider when making the move to an ultra-small-form-factor (USFF) system, a two-page features table covering everything you could want to know about each system on test, a look at external GPU (eGPU) products as a way of expanding the performance of mini-PCs, and a “View from the Labs” opinion editorial to round things out.

This feature also marks the first time the in-house PC Pro benchmark suite – which measures system performance for image editing, video playback, and multitasking workloads – has been run not only on Linux-based, rather than Windows, systems but also on a Raspberry Pi. To achieve that, I worked to port the PowerShell-based suite to the Bash shell while using the same cross-platform applications to ensure each platform can be compared as fairly as possible.

PC Pro Issue 297 is available now at all good supermarkets, newsagents, and digitally via Zinio and similar services.

Custom PC, Issue 186

Custom PC Issue 186This month’s Hobby Tech column features an interview with Eric Yockey on his company’s PC Classic microconsole, a review of the it-really-blows IT Dusters CompuCleaner, and of Eric Amos’ coffee-table tome The Game Console.

To start with the interview, Eric surprised the gaming world late last year by announcing what at first glance appears to be a me-too product following in the footsteps of the Nintendo Entertainment System Classic Mini and Sony PlayStation Classic, not to mention the raft of Atari- and Sega-licensed devices that came before them: the PC Classic, which aims to bring older games back to the living room.

“Our principal engineer saw that people were joking about things like ‘the VCR Classic’ and ‘the PC Classic’ and he pitched it to me because he felt we could actually make a PC Classic, and moreover make it really cool,” Eric told me during our interview. “I discussed the project with a bunch of people from various backgrounds and varying amounts of technical ability, and most people took an immediate liking to it and would say something like ‘oh, yeah, if I could play Jill of the Jungle on my couch, I’d totally buy one!'”

The CompuCleaner, meanwhile, is an attempt on my part to reduce my environmental impact and fatten my wallet: an electric air-blower which aims to replace cans of compressed air for cleaning electronics. Anyone who has an actively-cooled PC will know that the vents and fans need to be kept clear, but the problem only gets worse when you need to take photos of things for a living – and the CompuCleaner, bar a few little niggles, is a fantastic way to do that without running through half a dozen air cans a week.

Finally, Eric Amos’ The Game Console is an impressive book covering many – but far from all – games consoles from the early days of the Atari VCS up to more modern systems. Light on text, the book’s focus is Eric’s high-quality photography – imagery he took, initially, to contribute to Wikipedia in place of the often low-quality photography that adorned classic console pages. While it’s not something you’re likely to sit and read cover-to-cover, it’s not only a pleasing thing to flick through but a great way to support Eric’s work in taking ever more photographs of increasingly-esoteric hardware.

For all these, head to your favourite newsagent, supermarket, or stay where you are and download the digital version via Zinio or similar distribution services.

The MagPi, Issue 76

The MagPi Issue 76There’s no missing my contribution to this month’s The MagPi: it’s plastered all over the cover. The launch of the Raspberry Pi 3 Model A+ ends a four-year absence of the compact form factor from the Raspberry Pi line-up, and there’s no better way to celebrate its launch than with a massive cover feature.

The spread begins with a two-page introduction dominated by imagery of the board, before moving on to a plan view which calls out the individual components that make up the board – including the single USB port, BCM2387B0 system-on-chip (SoC), and the radio which, for the first time in a Model A variant, adds WiFi networking and Bluetooth connectivity. Each part includes macro photography, all taken in my in-house studio.

The next section of the feature runs through a series of benchmarks which, in-keeping with previous launches I’ve covered, compares the Pi 3A+ with other mainstream Pi models going all the way back to the original Raspberry Pi Model B. The feature also includes a look at the size and weight, the first time I’ve used that particular metric, along with comparative thermal imagery showing how the smaller surface area of the PCB copes with running the same high-performance processor as the larger Pi 3B+ – again, all captured in-house.

Finally, the cover feature closes with a two-way interview I conducted with project co-founder Eben Upton and principal hardware engineer Roger Thornton. In it, Eben confirms that the Pi 3A+ represents “tidying up ‘classic’ Raspberry Pi,” and that the Raspberry Pi 4 – still very much on the drawing board – will launch a whole new era for the low-cost single-board computer family.

The launch issue is available now from your nearest newsagent or supermarket in print, or can be downloaded free of charge under a Creative Commons licence from the official website.

The MagPi, Issue 68

The MagPi Issue 68The launch of a hardware refresh for the low-cost yet surprisingly-capable Raspberry Pi single-board computer is always a great opportunity to take stock of how the project has progressed since its launch six years ago, and the result is this: a special cover feature for The MagPi celebrating the release of the Raspberry Pi 3 Model B+, or Pi 3 B+ to its friends.

Following roughly the same format as my cover feature for the launch of the Raspberry Pi 3 from March 2016, and my cover feature for the Pi Zero’s launch back in November 2015, my multi-page feature begins with an overview of the board highlighting its key new features with high-resolution call-out photography: the new Broadcom BCM2837B0 system-on-chip which dispenses with the old plastic package for a new direct-die layout protected by a metal heatspreader; the new dual-band 2.4GHz and 5GHz Wi-Fi and Bluetooth radio module; a Pi Zero-inspired ground plane antenna, which boosts wireless performance still further; a Power over Ethernet (PoE) header for the optional PoE HAT; gigabit Network connectivity; and a custom-designed power management integrated circuit (PMIC) which improves regulation and assists with the clockspeed increase to 1.4GHz.

Taking a brief pause for a quick getting-started guide for those new to the Raspberry Pi, the feature then gets into its stride with a full suite of benchmarks across two pages. Measuring everything from CPU and memory performance to Ethernet throughput, power draw, and Wi-Fi signal quality, the benchmarks don’t just cover the Pi 3 B+ and its immediate predecessor; the benchmarks compare the new board to every single mainstream model of Raspberry Pi in the project’s history, all the way back to the original Model B from the initial pre-production run. If you’ve ever wondered how things have improved over time, this feature will let you know exactly that.

A further two pages are taken up by my interview with Raspberry Pi Foundation co-founder Eben Upton, who first introduced me to the project all those years ago. Diving into the changes and improvements made in the Pi 3 B+’s design, which is the work of engineer Roger Thornton, the interview also includes several behind-the-scenes images and – because I can never resist the opportunity – a thermal imaging analysis demonstrating how the new packaging and thicker PCB help the Pi 3 B+ deal with heat dissipation, despite its faster clock speed compared to the hot-running Pi 3.

To read through the full feature, which also includes a more detailed getting-started guide and ten project ideas which take advantage of the board’s increased power, head to your local newsagent, supermarket, or download the issue digitally under the permissive Creative Commons licence from the official website.

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.

The MagPi, Issue 49

The MagPi Issue 49The latest issue of The MagPi, the official magazine of the Raspberry Pi Foundation, includes my two-page interview with Grant Macaulay of Theo Lasers, along with what is now rapidly becoming a go-to image I took of a Raspberry Pi 3 artfully rotated and pasted onto the cover.

I first met Grant at the Maker Faire UK event earlier this year, and got talking to him about the project he had quit his job to build: Theo Lasers. Designed to address the lack of affordable entry-level laser cutters and engravers for hobbyist and educational use, Theo Lasers came from a simple idea: “I’m going to make a laser cutter with a laser cutter,” he laughingly explained in front of a stand of prototypes proving he could do just that.

In the months since the event, Grant has been hard at work improving upon his design. In particular, with the aid of a developer friend, he’s moved from basing the hardware on an Arduino Mega microcontroller to using a Raspberry Pi Zero. In doing so his team developed Theo Controller, a browser-based control and monitoring system which runs entirely on the Pi and which can accept input from any web-compatible device. Coupled with an on-board display, SD card reader, and even the ability to run from battery or solar power, and Grant’s design definitely stands out from the competition even before you see its eye-catching wooden chassis.

Grant’s due to launch a Kickstarter campaign to begin mass production of the Theo Laser cutters in early September, with more details available from the official website. The interview, meanwhile, can be read for free in the Creative Commons licensed The MagPi Issue 49, out now.

Custom PC, Issue 157

Custom PC Issue 157This month’s Hobby Tech column demonstrates how to use the Raspberry Pi Camera Module to create smooth timelapse footage and reviews the WeMos D1 R2 ESP8266-based Arduino-alike board and Andrew ‘bunnie’ Huang’s Essential Guide to Electronics in Shenzhen.

Looking to the tutorial, this is far from the first time I’ve covered the use of the Raspberry Pi Camera Module add-on. Since its initial launch, however, the software has come on in leaps and bounds including means of finally addressing a longstanding issue with the board: the difficulty in using the timelapse functionality. Where previously you needed a surprisingly complicated script to control the camera, now timelapse capture is handled entirely within the raspistill software. Coupled with avconv – ffmpeg, which I had previously recommended for the task, having been deleted from the Raspbian software repositories – the two packages are all you need to create high-quality timelapse footage directly on any Raspberry Pi.

The WeMos D1 R2 is one of a range of low-cost devices based on the ESP8266 microcontroller and Wi-Fi radio. While getting on in age, the ESP8266 is extremely popular due to its rock-bottom pricing; the only snag being that its form factor makes it difficult to integrate into hobbyist projects. The WeMos D1 R2 aims to fix that by providing a breakout board for the compact ESP8266 in the familiar Arduino Uno layout. While more feature-packed equivalents exist, the WeMos D1 R2 costs just £3.30 in single units – an absolute bargain for an easy-to-use microcontroller with integrated Wi-Fi connectivity.

Finally, The Essential Guide to Electronics in Shenzhen. Kindly loaned by my friend Aaron at hobbyist electronics specialist oomlout, this latest book from noted hacker Andrew ‘bunnie’ Huang is a major departure from the norm. Rather than a how-to guide or white paper analysis, the book is designed to be used as a functional sourcing tool while visiting the Shenzhen area of China complete with maps, point-to-translate pages covering everything from travelling back to your hotel to enquiring as to the tolerance of resistors and capacitors. A pair of prose sections also provide information on doing business in China, including how to spot fake or missold components and how each could affect your project. Niche, perhaps, but a fascinating read – and an invaluable tool for anyone planning a trip to Shenzhen any time soon.

All this, plus the usual raft of interesting things written by people who aren’t me, can be found at your local newsagent, supermarket, or as a string of zeroes and ones on Zinio and other digital distribution services.

Custom PC, Issue 155

Custom PC Issue 155This month’s Hobby Tech column features my field report from the Maker Faire UK 2016 event, an interview with my good friend Daniel Bailey about his brilliant homebrew computers, and a review of the Genuino MKR1000 microcontroller.

First, the event. Attending events like the Maker Faire is always a blast, especially as press when you have an excuse to stick your nose into absolutely everything that’s happening. My attendance this year was sponsored by oomlout, a local hobbyist electronics shop and a client for whom I do blog work, as highlighted in a “Sponsored By” call-out over the two-page spread. As for the event itself, you’ll find coverage of everything from DoES Liverpool’s excellent shooting gallery to affordable laser cutters and even the world’s only crowd-funded and wholly amateur manned space programme.

The event also gave me a chance to catch up with Daniel Bailey at the York Hackspace stand, after nearly a year of trying to find a good time to interview him about his impressive homebrew computers. Built on field-programmable gate arrays (FPGAs) and inspired by the classic Manchester Baby, the 8-bit C88 and 32-bit C3232 are incredibly impressive machines – and I can think of no project that better fits with the magazine’s title!

Finally, the MKR1000. Known under the Arduino brand in the US and Genuino brand elsewhere thanks to ongoing trademark disputes, the MKR1000 is Arduino.cc’s answer to the popular Particle Photon Wi-Fi microcontrollers. Featuring a breadboard-friendly layout and integrated 2.4GHz 802.11b/g/n Wi-Fi radio, it represents an interesting new direction for the company – albeit one somewhat hobbled by a high price compared against the competition.

All this, plus the usual raft of interesting things written by people other than me, is awaiting your attention at your local newsagent, supermarket, or electronically via Zinio and similar digital distribution platforms.

The MagPi, Issue 43

The MagPi Issue 43It’s a special week for the Raspberry Pi Foundation: it’s celebrating its fourth birthday with the launch of the new Raspberry Pi 3. It’s a special day for me, too: the latest MagPi magazine boasts a total of thirteen pages of my content, including the cover splash: a detailed and thorough look at the new model.

Boasting on-board Wi-Fi (a community request since the original model launched four years ago), Bluetooth 4.1, Bluetooth Low Energy, and a faster 64-bit ARMv8 processor, the new Pi 3 is a bit of a beast. My cover feature for the magazine begins with a look at those behind it with a double-page spread featuring interviews with project co-founder Eben Upton and the Foundation’s director of hardware and the man responsible for circuit design James Adams – and a massive thank-you to both for sparing the time to talk to me at one of their busiest ever periods!

The feature then moves on to a look a the board itself, with a hero photo of the board spread across another two pages. Each major feature of the board, from the shiny new 64-bit BCM2837 system-on-chip (SoC) processor to the BCM43438 radio module – which required me to get out the microscope in order to capture its markings – has a call-out with close-up photography and an explanation of how it has changed since the Raspberry Pi 2.

Next up is a benchmark spread, which required me to come up with a detailed suite of tests. After some experimentation, I settled on a selection of classic benchmarks – SysBench CPU in single- and multi-threaded modes, Linpack with and without NEON support, Whetstone, Dhrystone, SysBench memory read and write, Ethernet throughput, Quake III Arena timedemo performance, and power draw at load and idle. As an added bonus, I also came up with a way of measuring general-purpose input-output (GPIO) performance under Python, writing a simple benchmark to toggle a pin on and off as quickly as possible and measuring the speed with a frequency counter connected to the GPIO header.

The next double-page spread looks at helping the reader get started with the new device. I walk readers through modifying an existing Raspbian installation to boot on the Pi 3 by editing config.txt, setting up the Wi-Fi module, enabling true OpenGL acceleration on the graphics processor, and how to write programs to get the best performance on the Pi 3. Sadly, I was unable to explain how to use the Bluetooth 4.1 and Bluetooth Low Energy features, as software support was not available at the time of writing.

The spread then ends with a look at five things you could do with a Pi 3 in order to take advantage of the new features and boosted performance. My work for the magazine continues, though, with a review of the Proster VC99 multimeter and Pimoroni pHAT DAC, before coming to a close with a one-page news piece regarding the production status of the popular Raspberry Pi Zero – helping to explain why it has been so difficult to get hold of and settling concerns that it may be bumped to the back of the production queue now the Pi 3 is out.

All 13 pages of my content, and plenty of other stuff by people who aren’t me, are available from your nearest supermarket or newsagent, or as a free PDF download under a Creative Commons licence from The MagPi’s official website.

The MagPi, Issue 42

The MagPi Issue 42This month’s instalment of The MagPi, the official magazine of the Raspberry Pi Foundation, includes a short project I created upon request from editor Russell Barnes: soldering a reset switch to a Raspberry Pi Zero.

While part of a feature on projects specifically for the Zero, the reset switch mod is actually applicable to any modern Raspberry Pi. It makes use of the RUN header, which when shorted out causes the processor on the Pi to act as though the power has been briefly cut. The result: an instant hard reboot, even if you’ve found a way to crash the system hard. The header also doubles as a remote power switch: if the Pi is powered off but plugged into a live power supply, shorting the RUN header will begin the boot process.

Attaching a switch to the reset header is as simple as soldering two pins, but the audience of the magazine spans the gamut from absolute beginner to highly-qualified engineer. As a result, a very specific angle was chosen for the tutorial: introducing someone to the art of soldering, using the simple two-pin reset switch as a less daunting entry point than the significantly larger GPIO header soldering project found back in Issue 40.

As always, the tutorial includes plenty of photography taken in my home studio. For much of the work I do, I’ve found my Nikon 40mm macro lens to be indispensable; the only time it typically leaves my camera is if I’m doing portraiture or low-light photography (in which case it’s replaced by an f1.8 50mm prime lens) or if I need wide-angle or telephoto shots (15-35mm and 70-300mm lenses respectively) during event coverage.

The tutorial, plus various exciting Pi-related things written by people other than myself, can be found gracing the shelves of supermarkets and newsagents throughout the country, or can be downloaded free of charge from the official website under a Creative Commons licence.
