Get Started with Raspberry Pi

Get Started with Raspberry PiFollowing on from releasing the world’s first magazine with a computer on the cover, for which I provided the launch documentation that made up the historic MagPi Magazine Issue 40, Raspberry Pi Press has done it again: Its new publication, Get Started with Raspberry Pi, once again includes a cover-mounted computer – this time the more powerful Raspberry Pi 3 Model A+ – along with a case and pre-loaded microSD card with adapter.

The book, as its name suggests, is designed for absolute beginners to the Rasbperry Pi – but it’s not a replacement for my Official Raspberry Pi Beginner’s Guide, now in its third edition. Instead, it offers a broader but shallower overview of what the Raspberry Pi can do – starting with setting it up and moving on to both hands-on projects and an overview of community projects and third-party add-on hardware.

Inside Get Started with Raspberry Pi you’ll find a range of contributors’ work, including of course my own: The set-up guide and instructions on using the Raspbian desktop and other software, much taken from the Official Raspberry Pi Beginner’s Guide, bear my hallmark; the book also republishes the Raspberry Pi 3 Model A+ launch feature I wrote for The MagPi Magazine Issue 76, which includes an overview of the device, detailed benchmarking including how it relates to ever other model in the Raspberry Pi range, and an interview with its creators.

Those looking to get the bundled Raspberry Pi 3 Model A+ will need to head to their nearest supermarket, newsagent, or order a copy with free worldwide delivery from the Raspberry Pi Press Store; as with most Raspberry Pi Press publications, Get Started with Raspberry Pi is also available for free download under a Creative Commons licence – though, obviously, the download doesn’t include the cover-mounted computer!

Custom PC, Issue 185

Custom PC Issue 185In my regular Hobby Tech column this month you’ll find a detailed review of the Raspberry Pi 3 Model A+ single-board computer, another of the ever-so-slightly less-powerful Digirule2, and of Adam Fisher’s exhaustive Valley of Genius: The Uncensored History of Silicon Valley.

First, the Raspberry Pi. The first model to use the A+ form factor – smaller PCB, only one USB port, full-size display (DSI), camera (CSI), and HDMI ports, analogue audio-video (AV) – in the last four years, the Pi 3A+ is an impressive beast for cramming the full performance of the larger, more expensive Pi 3B+ into a smaller form factor. I was concerned, upon first unpacking, that the smaller PCB would undo the good work on the thermal-transfer front that made the Pi 3B+ such a good improvement on the original Pi 3B; a quick test under a thermal imaging camera, though, showed that I was worrying over nothing.

The Digirule2 is a markedly different beast. While it’s a single-board computer, it’s one which is designed more for fun than functionality: built into the form factor of a ruler, complete with inches and centimetres marked in binary along the upper and lower edges, the Digirule2 is inspired by classic machines like the Altair 8800. Press a series of buttons to program a particular memory location; press another button to switch to the next; and press a third to see your program run on the built-in LEDs. One particularly impressive feature is an eight-slot program storage, allowing you to save and load your programs directly on the device – and all without having to hook up your punch-tape reader/writer.

Finally, Adam Fisher’s Valley of Genius is a book in the mould of Fire in the Valley: an attempt to document the rise and, frankly, continued rise of Silicon Valley and the companies it has birthed. Culled from over 200 individual interviews, the book uses direct quotation rather than any attempt to weave a narrative but dodges dryness by weaving multiple subjects’ remembrances into each themed chapter. The final effect is less an interview and more a conversation between some of the industry’s biggest names, from the birth of the mouse right through to the modern age.

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.

Benchmarking the Raspberry Pi 3 Model A+

Back in March, the release of the Raspberry Pi 3 Model B+—the Pi 3 B+ to its friends—brought a chance to take stock and review just how far the project had come since its launch via a series of benchmarks. Now the launch of the Raspberry Pi 3 Model A+ brings a bold claim: a dramatic drop in size, weight, and price over the Pi 3 B+, but without any loss in performance.

In other words: it’s benchmark time once again.
