Make: Magazine, Volume 79

Make: Magazine Volume 79This month brings with it my first cover feature for a new client, and it’s one of which I’ve long been a fan: Make: Magazine, the maker-centric electronic hobbyist publication, now in its 79th volume.

For this issue, its biggest of the year, I contributed two features. The first is the biggest: the Boards Guide 2021, the latest version of the magazine’s annual pull-out reference to the latest single-board computers and microcontroller development boards around. It’s an undeniably handy guide, offering everything from key specifications – right down to the number of analogue inputs you’ll find on general-purpose input/output headers, as but one example – to up-to-date pricing, though the latter is rather more variable than usual thanks to continued supply chain issues and component shortages.

Having been provided with a list of the boards to be included, I went through and fact-checked all the specifications – filling in blanks where necessary. At one point, faced with a board for which no dimensions were publicly listed and for which the creator couldn’t be immediately contacted I turned to an unusual approach: estimating its size from a perspective-corrected image of the board, based on the spacing on the 2.54mm header. When I finally obtained official measurements just ahead of deadline, my estimate turned out to be accurate to two significant figures – and I can’t say I wasn’t thrilled!

The second feature, also available on the Make: Magazine website, takes a look at Raspberry Pi’s first in-house microcontroller, the RP2040, and its rapid adoption by third-party board makers. For this, I initially researched a list of nearly 80 RP2040-based devices – pulling in key specifications and features, as with the larger Boards Guide feature – which editor Mike Senese and I then narrowed down to a shortlist to be featured in the magazine and online. Finally, I prepared a brief write-up to accompany the shortlist.

Make: Magazine Volume 79 is available at all good newsagents now, and is available for print and digital subscription on the official website.
