The Whole Computer Is Vim

October 1, 2026 by Jenny List 30 Comments

Love it or hate it, Vim, the vi-compatible minimalist editor, is a common denominator between a huge array of operating systems. If you need to edit a file, it’s usually safe to expect it there if your normal editor is absent. Now thanks to [Omwah] it’s moved onto the most meager of platforms, where it becomes the firmware itself rather than a program running on an OS.

ESP-Vim is, as its name suggests, Vim, for some of the ESP32 series of microcontrollers. It boots straight into the familiar editor on an attached screen, and it has filesystem and git access, along with MicroPython. It’s a small computer for working with text files and some basic scripting, and we like the idea.

It needs a board with an ESP32-S3 or P4, with 16 MB of Flash and at least 8 MB of PSRAM. There’s a list of boards that meet this spec, and we can’t help noticing that one of them is the version of the Cheap Yellow Display that comes with an S3. Hook up a Bluetooth keyboard and you’re in.

How easy it will be to use remains to be seen, but bearing in mind that the vi interface followed by Vim was designed for very slow terminals in a much earlier decade, and it could be just right for these platforms. Would you use one?

No More Windows For The Dutch Government, Ze Kiezen Nu Linux

September 29, 2026 by Jenny List 84 Comments

The events of the last few years have caused many in Europe to re-evaluate their reliance on large offshore technology companies, with a corresponding move to home-grown EU-based alternatives. It’s one thing when individuals or companies do this, but another entirely when it’s an entire country. So the news that the Netherlands is building their own Linux distribution to replace Microsoft Windows in government installations, is not inconsequential. The Tweakers site linked actively breaks out of Google Translate, so you may have to rely on your browser’s translation tool if you are not a Dutch speaker.

The Digitaal Autonome Werkomgeving Overheid, or Digital Autonomous Work Environment, is a distro based upon NixOS, itself originally a product of a Dutch university. It comes complete with all the office and collaboration applications needed to replace Windows, and is reported to have been tested already by a small group of Dutch government workers.

The influence of this move is likely to be a huge one for Microsoft, given that governments have huge numbers of operating system seats. But perhaps more important than the OS itself are the extras that Microsoft would like to sell to its OS customers, such as AI services. We’d expect that there will be managers in Redmond paying close attention to Europe in the wake of this move.

Meanwhile the Netherlands has a vibrant hacker community, and we can imagine that this move will be welcomed in those quarters. All Netherlands government online services are accessed through an ID verification app called DigID, and it’s a lament we’ve heard from our Dutch friends that this only works with Windows, Android and Apple platforms. If this means a Linux version will appear on the back of an NL government Linux distro, we know some people who will be very happy indeed.

Places To Visit: Landschaftspark Duisburg-Nord

September 28, 2026 by Jenny List 18 Comments

There are many benefits to spending time in the park, but perhaps few of them have a Hackaday angle. There’s a park in Germany you might want to make an exception for, and it lies in the Ruhrpott city of Duisburg.

I was lucky enough last month to join a friend as she toured Germany for the first time with a caravan. It’s a large country with many beautiful places, so her choice might seem unexpected at first sight. The Ruhrpott, or Ruhr area, is a loose conurbation of industrial cities that loosely follows the river Ruhr on its trip to the Rhine on the western edge of the country. It’s close to deposits of coal and iron ore, so just like similar areas in other countries, it became a centre for heavy industry. Today that continues, but as you might expect it’s also dotted with the remains of former industries. It’s one of those which is our subject for today, and it offers a very unusual opportunity.

A view out over a wooded post industrial landscape against a grey cloudy sky. In the foreground is a hiuge traverser crane. — Looking out over the former ore bunkers shows just how huge this site is.

Landschaftspark Duisburg-Nord is a forest park on the northern side of the city of Duisburg. But of course that’s not the whole story, because until 1985 it was the site of the Thyssen ironworks. In rehabilitating the site they chose to keep the main structures of the ironworks intact as they reclaimed the surrounding polluted industrial land, so today it may be one of the few places in the world where you can free of charge get up-close and personal with a fully-intact and preserved blast furnace. The site has three of them remaining along with their associated ore and gas processing plants, and the largest and newest, blast furnace number 5, is a structure you can climb to its top. If you’ve ever been curious about iron smelting, this is the place to come. Continue reading “Places To Visit: Landschaftspark Duisburg-Nord” →

You Can Make A Microprocessor That’s All Your Own

September 26, 2026 by Jenny List 7 Comments

For a while now we’ve followed the slow progression of affordable integrated circuit fabrication, and through the likes of Tiny Tapeout we’ve seen impressive strides made. But they’re not the only player in the space, and [Breaking Taps] has a video showing their microprocessor built using wafer.space.

The microprocessor itself is a little unusual, being a transport triggered architecture design with two busses. The whole thing might better be described as a system-on-chip than a microprocessor, as like a microcontroller it contains both memory and peripherals. He’s used Spade to design the thing, and we get an in-depth look at all the steps involved between design and fabrication. It’s a level or two more difficult than passing the DRC standards for your PCB fabricator. The result is a chip carrier with the chip itself visible under clear epoxy. It’s using an old fabrication technology so the silicon is surprisingly big, but unlike Tiny Tapeout’s cell based fabrication the whole chip is the one circuit. Mounting it on a PCB and using a breadboard, he’s able to demonstrate it running simple programs.

It’s clear that having your own IC fabricated is not for everyone, as even though wafer.space has performed minor miracles it’s still a service for people with a few dollars in hand. But look at it this way, we’re still near the start of this particular curve, and we expect that further affordability breakthroughs will follow.

Did The BBC And Sir Clive Get It Right Twenty Years Ago?

September 25, 2026 by Jenny List 17 Comments

Predictions of the future are often laughable when reviewed in the years for which they are made. For example, here in 2026 we neither live on the Moon, nor have flying cars. But sometimes they come closer to the reality than others, and in that the BBC Archive have an interesting offering. It’s a Newsnight feature from 2006 looking at the future of artificial intelligence, and since its main interviewee is none other than Sir Clive Sinclair, it’s worth a second look.

Watching the video it’s a shock to be reminded that 2006 was twenty years ago, as in so many ways it’s close enough to touch. Back then we had laptops with Windows or Linux, we had the Web, and HDTV, as we do today. But as we sat in our Ford Focus family car it would be on a Nokia that we rang home; while technically a smartphone it was nothing like the Apple and Android devices that would take the world by storm in the following years. Sir Clive is positive about the development of AI as he saw it then, seeing it as providing knowledge based services such as education or healthcare from your computer. The following interviewee from British Telecom perhaps puts his finger on the pulse the most, predicting a path “Over the next few years” that seems pretty familiar to us a couple of decades later.

So for once this is a future prediction that doesn’t seem too outlandish. Aside from Sir Clive’s appearance it’s packed with retro technology goodies, so it’s well worth a watch below.

A Tiny Toy Synth For Smaller Computers

September 23, 2026 by Jenny List 5 Comments

Even for the non-musical among us there is a lot of fun to be had with a simple synthesiser and sequencer, as the different controls can be manipulated to show their effect on the sound. Beeper, from [Valentyn Danylchuk] is just such a synth, and with only built-in loops, it has a focus on the instrument rather than the arrangement. What you get are a simple set of controls, from which you can modify the sound to your liking. We’ve been playing with it here, and it’s surprisingly addictive.

The target for Beeper is ESP32 microcontrollers, with builds for the S3 and P4, but there’s also a web version and one for the Mac. It’s operated using the arrow keys on your keyboard, and the web one at least isn’t the most responsive piece of software. Below the break you can see (and hear) it on a Tanmatsu ESP32-P4 based handheld computer.

It’s certain that there are more accomplished synthesisers and sequencers to be found, but there’s still a place for one that’s simply a musical toy like this. Sometimes playing with something is more important than achieving something with it.

Smelting Bog Ore As It Should Be Done

September 23, 2026 by Jenny List 18 Comments

Sometimes along comes a hack with a personal angle, and in a video showing Irish bog ore smelting, we find an appropriate follow up to a Hackaday expedition back in 2019. [Alec Steele] joined Irish Bloomery Iron, for a weekend with a medieval blast furnace.

Our brush with bog ore came in a trip to Hack42 in Arnhem, the Netherlands, where a team of Dutch hackers built a furnace from firebricks in an attempt to do the same thing. The Dutch attempt ended with a lot of mixed slag and very little iron, and looking at how the Irish furnace was constructed we see some clues to their success. Their air injection using a perforated sheet of clay and the air blast injected to form a venturi is particularly interesting,as is the shape of the furnace.

The iron bloom is lifted out through the top of the furnace rather than being tapped as molten iron, and we’re treated to it being worked into a usable bar of iron. Having spent a day with our Dutch friends doing the same work only to have scraps of iron, we’re mightily impressed with the results from the Irish smelters.
