Get Started with MicroPython on Raspberry Pi Pico, 2nd Edition

Leave a comment

I’m ecstatic to announce the launch of my latest book: the second edition of Get Started with MicroPython on Raspberry Pi Pico, the best-selling guide to using MicroPython on a Raspberry Pi Pico microcontroller board – now fully updated for the Raspberry Pi Pico W.

The revised larger edition comes with additional chapters specific to the Raspberry Pi Pico W, a device which can do everything the Raspberry Pi Pico can do and more – thanks to the addition of a radio module capable of Bluetooth and Wi-Fi communications. New projects include connecting to a Wi-Fi network, querying remote servers, and hosting a web page capable of interacting with the Raspberry Pi Pico W’s general-purpose input/output pins, plus configuring a Raspberry Pi Pico W as a Bluetooth beacon – connecting, if you’ve got one, to your phone or a second Raspberry Pi Pico W.

It’s not just about the new chapters, though. This second edition offers a complete overhaul: all projects have been brought up-to-date with the latest MicroPython advancements, a now hard-to-find display component has been swapped out for something more readily available at a lower cost, and the ever-talented Sam Adler has created all-new illustrations to bring the book’s look and feel in-line with my recently-launched The Official Raspberry Pi Beginner’s Guide 5th Edition.

As always, I want to thank everyone at Raspberry Pi Press for their work in helping me make this the best book it could be: editor and publishing director Brian Jepson, co-editor Liz Upton, interior designer Sara Parodi, Nellie McKesson in production, photographer Brian O’Halloran, graphics editor Natalie Turner, and head of design Jack Willis, plus everyone else involved in getting the book to shelves today.

Get Started with MicroPython on Raspberry Pi Pico 2nd Edition is available from all good bookshops and Raspberry Pi resellers now, as well as on the official Raspberry Pi Press store for global delivery; if your bookseller doesn’t have a copy, or if you’d like to request it from your library, you can ask for it under ISBN 978-1-912047-29-1.

As always, I hope you have as much fun reading the book as I did writing it!

Digital Roundup – June 2024

Leave a comment

Another month flips over on the calendar, and it’s time to take stock of my digital work in June. The month saw my pile of to-review hardware drop a little, thanks to the publication of my hands-on reviews of the Jumperless breadboard and the Arduino PLC Starter Kit over on Hackster.io.

Reviews are always a lot of work, but fun with it. As always, I handle the product photography myself in-house – and June’s shots have come out splendidly. The Jumperless was a little more of a challenge than usual, thanks to the presence of hard-to-capture RGB LEDs viewable only from a very precise top-down angle, but I’d like to think the results speak for themselves.

The to-review pile isn’t exhausted yet, though, so expect to see more reviews in July, along with my usual newsletters and news articles.

Digital Roundup – May 2024

Another month has passed, and it was a shorter one for me thanks to a week’s break with the family – and the kids’ first trip abroad, if you don’t count crossing the northern border into Scotland.

Despite this, I’ve had a bumper crop of articles published online in May. Highlights include the launch of the Raspberry Pi AI Kit, in partnership with Hailo, and the Raspberry Pi Connect browser-based remote access platform, Lex Bailey’s incredible Sinclair ZX Spectrum-powered laptop, Pineberry Pi’s relaunching as Pineboards as it looks to branch out from Raspberry Pi accessories, neuromorphic computing in space, a one-Euro RISC-V personal computer, and a project to encode sound as serial data and play it back with nothing more than a resistor and a capacitor.

My hands-on review on the unPhone, an educational tool which combines the core features of a smartphone bar the actual “phone” parts and lives at the heart of an Internet of Things course at the University of Sheffield, was published on Hackster.io too – and will be followed by additional reviews this June.

Digital Roundup – April 2024

The calendar has flipped over once more, meaning it’s time to take stock of everything I’ve covered over the past month – and what a month it’s been.

April has seen my interview with Matt Venn on the Tiny Tapeout project and related topics land on the Make: website, fresh newsletters for the MyriadRF project and the Free and Open Source Silicon Foundation (FOSSi Foundation), the launch of new Raspberry Pi Compute Module boards – though, sadly, not the ones for which everyone’s waiting – Espressif’s acquisition of M5Stack right before it launches a device powered by competitor STMicro’s silicon, a tiny ZX Spectrum-inspired games console, a major hardware upgrade for the MNT Reform laptop, and the promise from Syntiant that its latest “Neural Decision Processor” can deliver 30 giga-operations per second (GOPS) of compute in a microwatt power envelope.

The biggest news, however, was Zilog’s decision to discontinue the venerable eight-bit Z80 microprocessor family – just short of it reaching its 50th anniversary. The move does, at least, finally put to rest many a 1980s playground argument over whether the Zilog Z80 or the MOS 6502 is the superior chip – the 6502 having been selected to prove a foundry model for the production of fully-flexible semiconductors, a paper on which was published this month.

Special thanks to Professor Hamish Cunningham who, following my covering the project on Hackster.io, kindly sent me an unPhone to try – expect to see a hands-on review of that clever little gadget in the near future.

Now to see what May brings!

Digital Roundup – March 2024

Leave a comment

March has been another busy month for digital work, with plenty of news coverage – everything from stealing a car with a Flipper Zero to the launch of the first 64-bit STMicro STM32 microcontrollers (which, confusingly, retain the “32” moniker) and Renesas’ first to feature its in-house proprietary RISC-V core design.

I’ve covered Andrew “bunnie” Huang’s continued work on the Infrared In-Situ (IRIS) silicon inspection project, a vacuum-tube PDP-8 clone, the third-generation “wafer scale” chip from Cerebras, and a 30-cubit quantum computer for your desk – in simulation, at least — along with an “invisible drone,” the KingKong edge AI camera system, and an “inception” attack against virtual reality users.

In chronological order:

Digital Roundup – February 2024

Leave a comment

Another month has gone by, so it’s time to gather together everything I’ve written for digital publication over the past four-or-so-weeks.

It’s been a busy February, and a day longer than usual to boot, but if I had to pick some personal highlights they’d include this dual-display sunlight-readable PDA build, a tiny $5 mechanical keyboard, Paul Krizak’s amazing Wire Wrap Odyssey microcomputer, an anonymously-published 6,000 PPI boardview of the Nintendo Switch Lite, Wojciech Graj’s audio-only Doom port, and Tankgrrl’s Commodore 1541-style housing for a USB floppy drive.

Digital Roundup – January 2024

An increasing proportion of my work is now for publication online rather than in print, leading to this: the first in a new monthly round-up series covering all the articles I’ve had published over the past calendar month.

Make: Magazine, Volume 87

Leave a comment

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.

The Official Raspberry Pi Beginner’s Guide, 5th Edition

1 Comment

I am thrilled to announce the release of The Official Raspberry Pi Beginner’s Guide, 5th Edition – the latest incarnation of my book on the world’s most popular single-board computer, brought bang up to date for the Raspberry Pi 5 and the new Debian Bookworm-based Raspberry Pi OS software.

The new Beginner’s Guide has enjoyed a complete overhaul. Brian Jepson, the new head of publishing at Raspberry Pi Press, has introduced a new production approach which has resulted in a book that’s sleeker, cleaner, and more accessible than ever before – and at a beefy 278 pages, it’s also the longest edition yet.

That extra length comes courtesy of the inclusion of a bonus chapter on the Raspberry Pi Pico and Pico W microcontrollers, which serve as excellent companions to the main Raspberry Pi single-board computers. There’s also a fully updated getting started guide for setting up the Raspberry Pi 5, as well as the Raspberry Pi 400 and Raspberry Pi Zero 2 W.

This is my first time working with Brian, and it’s been a blast – from getting to grips with a whole new and considerably sleeker production process, which will mean easier updates in the future, to going through the material with a fine-tooth comb to make the book the best it could possibly be. Thanks too go to everyone else involved in the process: editor Liz Upton, interior designer Sara Parodi, Nellie McKesson in production, Brian O’Halloran for new photography, graphics editor Natalie Turner, head of design Jack Willis, and of course returning illustrator Sam Alder, plus all the others at Raspberry Pi Press.

The publication of the 5th Edition in English won’t be alone on the shelves for long, either, with Brian having confirmed translations into more languages than ever before: Danish, French, German, Greek, Italian, Polish, Japanese, Norwegian, Portuguese, Spanish, and Swedish.

The Official Raspberry Pi Beginner’s Guide, 5th Edition is available in all good bookstores now, in Raspberry Pi Stores and authorised resellers, and online with global delivery from the Raspberry Pi Press store; a digital copy will also appear, free of charge, in the Raspberry Pi Bookshelf app on Raspberry Pi OS in the next few days.

I hope you have as much fun reading it as I did writing it.

Custom PC, Issue 235

Leave a comment

Custom PC Issue 235This month’s Custom PC Magazine brings with it some sad news: the magazine is no more, with the printers falling silent in the face of growing print and distribution costs. That doesn’t mean Custom PC, long a staple of the enthusiast sector, is going away: editor Ben Hardwidge is to lead a new website, dedicated to the magazine’s core topics of mainstream Intel/AMD Windows-based PCs – which, unfortunately, means that my Hobby Tech column will not be making the transition.

Custom PC was my first print byline, and I’ve been writing for the magazine near-continuously my entire career. Hobby Tech itself has been running in the magazine for two months short of a full decade without a single missed deadline, over which time I’ve seen hobbyist products launch and prosper or wither on the vine – along with, of course, a sprinkling of vapourware. I’ve created benchmarks for microcontrollers and single-board computers, put together a custom workflow for high-resolution thermal imagery with visible-light backdrops, taken and edited quite literally thousands of photographs, reviewed hardware, software, and books, interviewed a broad range of people, and penned guides for everything from a hardware RSS feed reader to compiler optimisation.

I am determined that this will not be the end of Hobby Tech, which has long been a popular section of the magazine. In the coming months I’ll be seeking a new outlet for the column – and if you have a publication you think may be interested, please do send the editor my way!

For this final issue of Custom PC, meanwhile, I took a look at the impressive Open Circuits, the CRUMB Circuit Simulator, and the news of Sipeed’s upcoming LM4A system-on-module and PINE64’s PineTab2.

Open Circuits, to start, is Eric Schlaepfer and Windell H. Oskay’s love-letter to electronics. Published by No Starch Press, the hardback tome is a full-colour investigation of what actually goes into electronic components – from multi-layer printed circuit boards and integrated circuits to vintage devices like valves and simple gadgets like switches. We’re not just talking theory, here: the authors literally grind the components down to reveal their inner workings, capturing cross-sectional imagery which you won’t find anywhere else.

Originally a mobile app and now available on Valve’s Steam, Mike Bushell’s CRUMB is another way of looking at electronics – allowing you to build surprisingly complex circuitry in a realistic 3D environment from virtual components. Using SPICE for the actual simulation work, CRUMB offers a drag-and-drop approach to breadboard projects which keeps your desk free of clutter and which is surprisingly detailed – though perhaps a little tricky to operate at times.

All this, and more, is available for a limited time at your nearest newsagent or supermarket – for the last time ever. Goodnight, Custom PC Magazine, and rest well.
