Make: Magazine, Volume 87

It’s that time of year again: the 2024 issue of Make: Magazine’s Guide to Boards is on-shelves, with the annual insert offering at-a-glance comparisons of a total of 81 microcontroller and single-board computer development boards. Inside the main magazine you’ll also find a four-page feature on Matt Venn’s remarkable Tiny Tapeout project, while my annual piece on the state of the industry sits at the front of the insert.

First, the insert itself. For those unfamiliar, Make: Magazine’s Guide to Boards is a definitive pamphlet designed to provide the specifications – from size and power requirements to processor cores and memory – of the most popular, interesting, or unusual microcontroller and single-board computer development boards around. Updated annually, it offers at-a-glance comparatives to help you pick the hardware for your next project – and, as in previous years, I was given the opportunity to select boards for inclusion and update the data ready for the new year.

At the front of the 12-page insert, which covers a total of 81 boards this year, I also penned a piece on the industry’s exit – by and large, with a few exceptions – from the long-running component shortage crisis. The majority of boards which had been out-of-stock or in short supply for a year or more are now flowing freely, and both Arduino and Raspberry Pi have even been able to launch new designs: the Arduino Uno R4 family and the Raspberry Pi 5. Thanks here go to Adafruit’s Limor Fried and Raspberry Pi’s Eben Upton for taking the time to talk to me for the piece.

Thanks, too, are due to Matt Venn, creator of the Zero to ASIC Course and recently-launched Tiny Tapeout – educational courses which teach anybody how to make their own application-specific integrated circuit (ASIC), with hardware delivered at the end for you to try. From its origins in being prepared at just the right time to the success of its initial production runs, this four-page feature in the magazine proper offers an insight into Venn’s impressive work in democratising chip design.

As an added bonus, I was also selected to provide my opinion on the world’s greatest fictional spy to tie in with the issue’s feature on DIY spy gadgetry: see the contributors’ boxout on Page 4 for my answer!

All this and more is available in Make: Magazine Volume 87, available in well-stocked bookshops and newsagents now or online with global delivery from the Maker Shed.

Raspberry Pi: 21 Brilliant Projects

Raspberry Pi: 21 Brilliant ProjectsA few months ago I was approached by PC Pro’s Priti Patel with a project proposal: a MagBook featuring a number of interesting projects for the low-cost Raspberry Pi microcomputer. I, naturally, jumped at the chance, and the fruit – pun entirely intended, I’m afraid – of my labour is now available.

Entitled Raspberry Pi: 21 Brilliant Projects, the MagBook features 141 full-colour pages of projects designed for beginner to intermediate users. The introductory projects are, as you might expect, gentle indeed: unboxing and connecting the Pi, installing an operating system via the New Out-Of-Box Software (NOOBS), and the like. From there, the MagBook then covers four project categories: Productivity, Entertainment, Plug-In Hardware and DIY & Advanced.

In the Productivity chapter, I walk the reader through safely overclocking the Pi to boost its performance, sharing a keyboard and mouse with a desktop without the need to move any cables, using the Pi as a thin client for a desktop or laptop running Windows, OS X or Linux, setting up a TOR proxy, and installing and running the popular WordPress blogging platform.

In Entertainment, readers see how to convert any TV with HDMI, DVI, SCART or composite video inputs into a smart TV, work with Minecraft Pi Edition, emulate vintage gaming platforms, and build a headless Internet radio receiver.

For the Plug-In Hardware chapter, I wrote up how to build a digital photo frame, the use of USB-connected application-specific integrated circuits (ASICs) to mine Bitcoins, a Twitter-powered motion-sensing security system, how to configure the Pi for fully wireless use, and how to combine the power of the Pi with that of the Arduino microcontroller.

Finally, in the DIY & Advanced section, the reader learns how to use the Pi’s general-purpose input-output (GPIO) capabilities to build a traffic light system, create a doorbell that sends Twitter messages when activated, drive motors for a robotics system, build a custom arcade controller, create an Internet of Things printer, and how to cluster multiple Raspberry Pi units together to boost performance.

The MagBook is available in supermarkets and newsagents now, and will soon start shipping from Amazon UK for £9.99.

Custom PC, Issue 126

Custom PC Issue 126My monthly Custom PC column, Gareth Halfacree’s Hobby Tech, continues with a look at the toys and projects that have been entertaining me over the past four weeks including the acquisition of a core memory module, the Raspberry Pi GertDuino add-on board, and a guide – teased on the cover splash – to mining the Bitcoin cryptocurrency on said Pi.

First, the GertDuino. I won’t repeat myself with a summary of the device’s features – which are readily available in my review summary for Linux User & Developer Issue 135 – except to say that, as is usual for reviews in Hobby Tech, the review is written from a very personal perspective. As a result, the reader can enjoy a summarised version of my first few days with the device – including the heartache I had getting the blessed thing to work with the Arduino integrated development environment (IDE).

For the usual vintage computing portion of the column, I took a look at a new – to me – acquisition: a core memory module, pulled from a Soviet-era industrial computer of some description. The predecessor to modern transistor-based memory, magnetic core – literally a mesh of magnetic toroids which can be flipped to hold either a 0 or a 1 – has had an inestimable impact on modern computing, to the point where even today the process of saving memory contents to permanent storage for review is known as a ‘core dump.’

Also, the thing looks amazing under a microscope.

Finally, this month’s semi-regular tutorial section looks at using a USB-connected application specific integrated circuit (ASIC) to rapidly mine the Bitcoin cryptocurrency on a low-power Raspberry Pi. Prompted by my good friend Martyn Ranyard – the joint owner of a considerably more powerful mining rig than the one I created – the tutorial walks the reader through the exact steps I took to add Bitcoin mining facilities to my multipurpose Pi-based home server.

All this, plus a bunch of interesting stuff written by people who aren’t me, can be yours with a trip to your local supermarket, newsagent or a digital purchase on distribution services like Zinio. If you’d rather not risk missing an issue, Dennis Publishing is currently offering subscriptions at 50 per cent off the normal rate until the 31st of January.
