Digital Roundup – August 2024

Another month draws to a close, and it’s time to take stock of every article I’ve had published digitally over the past month.

The highlight of the month was, of course, the launch of the Raspberry Pi Pico 2 and its dual-architecture quad-core RP2350 microcontroller – one of a number of RISC-V design wins in August, as the free and open source instruction set architecture gains serious momentum. While some of the shine has been taken off the RP2350’s launch by the discovery of a hardware flaw, addressed in official erratum RP2350-E9, plenty of third parties have either pledged to adopt the part or have already launched hardware based around it.

Other topics of note this month include a great project from Guy Dupont to have a mouse play a game of Pong entirely in-firmware, relying on persistence of vision to have the cursor appear to be both bats and the ball simultaneously, Tim Alex Jacob’s work to give an existing LED badge design to the ability to be updated via flashing lights Timex DataLink-style, the impressive HaLiTerm Mini handheld, and an exerciser for your tired old floppy drives.

All this, and two newsletters to boot – what a month!

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

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

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.
