Maplin For Sale

February 24, 2018 by Jenny List 78 Comments

If you are an American Electronics Enthusiast of a Certain Age, you will have misty-eyed reminiscences of the days when every shopping mall had a Radio Shack store. If you are a Brit, the name that will bring similar reminiscences to those Radio Shack ones from your American friends is Maplin. They may be less important to our community than they once would have been so this is a story from the financial pages; it has been announced that the Maplin chain is for sale.

Maplin started life as a small mail-order company supplying electronic parts, grew to become a large mail order company selling electronic parts, and them proceeded to a nationwide chain of stores occupying a similar niche to the one Radio Shack fitted into prior to their demise. They still sell electronic components, multimeters, and tools, but the bulk of their floor space is devoted to the more techy and hobbyist end of mass-market consumer electronics. As the competition from online retailers has intensified it is reported that the sale may be an attempt to avoid the company going into administration.

It’s fair to say that in our community they have something of a reputation of late for being not the cheapest source of parts, somewhere you go because you need something in a hurry rather than for a bargain. A friend of Hackaday remarked flippantly that the asking price for the company would be eleventy zillion pounds, which may provide some clues as to why custom hasn’t been so brisk. But for a period in the late 1970s through to the 1980s they were the only place for many of us to find parts, and their iconic catalogues with spaceships on their covers could be bought from the nationwide WH Smith newsagent chain alongside home computers such as the ZX Spectrum. It’s sad to say this, but if they did find themselves on the rocks we’d be sorry to see the name disappear, but we probably wouldn’t miss them in 2018.

One of the things Maplin were known for back in the day were their range of kits. We’ve shown you at least one in the past, this I/O port for a Sinclair ZX81.

Footnote: Does anyone still have any of the early Maplin catalogues with the spaceships on the cover? Ours perished decades ago, but we’d love to borrow one for a Retrotechtacular piece.

“The Commodore Story” Documentary Premieres Today

February 23, 2018 by Dan Maloney 49 Comments

What is it about a computer that was introduced 36 years ago by a company that would be defunct 12 years later that engenders such passion that people still collect it to this day? We’re talking about the Commodore 64, of course, the iconic 8-bit wonder that along with the other offerings from Commodore International served as the first real computer to millions of us.

There’s more to the passion that Commodore aficionados exhibit than just plain nostalgia, though, and a new documentary film, The Commodore Story, seeks to explore both the meteoric rise and fall of Commodore International. Judging from the official trailer below, this is a film anyone with the slightest interest in Commodore is not going to want to miss.

It will of course dive into the story of how the C64 came to be the best selling computer in history. But Commodore was far from a one-trick pony. The film traces the history of all the Commodore machines, from the PET computers right through to the Amiga. There are interviews with the key players, too, including our own Bil Herd. Bil was a hardware engineer at Commodore, designing several machines while there. He has shared some of these stories here on Hackaday, including the development of the C128 (successor to the C64) and making the C64 speak.

We can’t wait to watch this new documentary ~~and luckily we won’t have to~~. It’s set to start streaming on Netflix, Amazon, and iTunes ~~today, so pop up some popcorn and settle in for a two-hour ride through computer history~~ but right now we’re unable to get firm dates on when. However, those of you in the Mountain View area have an even better opportunity this evening.

The Commodore Story will be premiered live at 6:30pm PST at the Computer History Museum. Grab your tickets to the premiere and a Q&A session with Bil Herd, Leonard Tramiel, and Hedley Davis.

France Proposes Software Security Liability For Manufacturers, Open Source As Support Ends

February 22, 2018 by Jenny List 58 Comments

It sometimes seems as though barely a week can go by without yet another major software-related hardware vulnerability story. As manufacturers grapple with the demands of no longer building simple appliances but instead supplying them containing software that may expose itself to the world over the Internet, we see devices shipped with insecure firmware and little care for its support or updating after the sale.

The French government have a proposal to address this problem that may be of interest to our community, to make manufacturers liable for the security of a product while it is on the market, and with the possibility of requiring its software to be made open-source at end-of-life. In the first instance it can only be a good thing for device security to be put at the top of a manufacturer’s agenda, and in the second the ready availability of source code would present reverse engineers with a bonanza.

It’s worth making the point that this is a strategy document, what it contains are only proposals and not laws. As a 166 page French-language PDF it’s a long read for any Francophones among you and contains many other aspects of the French take on cybersecurity. But it’s important, because it shows the likely direction that France intends to take on this issue within the EU. At an EU level this could then represent a globally significant move that would affect products sold far and wide.

What do we expect to happen in reality though? It would be nice to think that security holes in consumer devices would be neutralised overnight and then we’d have source code for a load of devices, but we’d reluctantly have to say we’ll believe it when we see it. It is more likely that manufacturers will fight it tooth and nail, and given some recent stories about devices being bricked by software updates at the end of support we could even see many of them willingly consigning their products to the e-waste bins rather than complying. We’d love to be proven wrong, but perhaps we’re too used to such stories. Either way this will be an interesting story to watch, and we’ll keep you posted.

Merci beaucoup [Sebastien] for the invaluable French-language help.

Help Keep The Bombe At Bletchley

February 17, 2018 by Jenny List 36 Comments

Fans of vintage codebreaking machinery might be interested to hear that the only working reconstruction of a Turing-Welchman Bombe is likely to soon be on the move. The electromechanical device, a replica of those used on the Second World War Enigma codes, is housed at Bletchley Park, the former codebreaking center established before the outbreak of war to house British and Polish codebreakers.

Bletchley Park itself is now a tourist attraction. The news is that a display reorganization has caused the Turing Welchman Bombe Rebuild Trust that owns the Bombe to approach the neighboring National Museum Of Computing with a view to housing it alongside their reconstruction of the Colossus electronic computer. The Colossus was famously used on the Lorenz cipher. This is an exciting development for the museum, but as an organization reliant on donations they face the task of finding the resources to create a new gallery for the arrival. To that end, they have launched a crowdfunding campaign with a target of £50000 ($69358.50), and they need your donations to it for the project to succeed. They have raised over £4500 in the few days it has already been open and there is most of a month still to go, so we hope they achieve their goal.

The Bletchley Park site is now surrounded by the post-war new town of Milton Keynes, and is easy enough to get to should you find yourself in the UK. We visited The National Museum Of Computing a couple of years ago and spent a very happy day touring its extensive and fascinating collection. If you want to read more about the Bombe you might like to read our review, and also our impression of Colossus.

As part of their campaign, the museum has produced a promotional video, which we have placed after the break.

There’s Now A New MIDI Spec, And Drones

February 16, 2018 by Brian Benchoff 42 Comments

MIDI, the Musical Instrument Digital Interface, was released in 1983 in a truly bizarre association between musical instrument manufacturers. At no other time, before or since, has there been such cooperation between different manufacturers to define a standard. Since then, the MIDI spec has been expanded with SysEx messages, the ability to dump samples via MIDI, redefining the tuning of instruments via MIDI to support non-Western music, and somewhere deep in the spec, karaoke machines.

Now there’s a new update to the MIDI spec (Gearnews link, here’s the official midi.org announcement but their website requires registration and is a hot garbage fire). At this year’s NAMM, the place where MIDI was first demonstrated decades ago, the MIDI Manufacturers Association announced an update to MIDI that makes instruments and controllers smarter, and almost self-learning.

There are three new bits to the new update to the MIDI spec. The first is Profile Configuration, a way to auto-configure complex controller mappings, described as, ‘MIDI Learn on steroids’. The second update is Property Exchange, and allows MIDI devices to set device properties like, ‘product name, configuration settings, controller names, and patch data’. This is effectively setting metadata in controllers and devices. The third new bit is Protocol Negotiation, a way to automatically push future, next-gen protocols over a DIN-5 connector.

What does this all mean? Drones. No, I’m serious. The MIDI association is tinkering around with some Tiny Whoops and Phantoms, and posted a video of drones being controlled by a MIDI controller. Play a glissando up, and the drone goes up. You can check out a video of that below.

Particle Introduces New Hardware, Adds Mesh Support

February 13, 2018 by Brian Benchoff 34 Comments

Particle, makers of the WiFi and Cellular IoT modules everyone loves, is introducing their third generation of hardware. The Particle Argon, Boron, and Xenon are Particle’s latest offering in the world of IoT dev boards, and this time they’re adding something amazing: mesh networking.

The three new boards are all built around the Nordic nRF52840 SoC and include an ARM Cortex-M4F with 1MB of Flash and 256k of RAM. This chip supports Bluetooth 5 and NFC. Breaking the new lineup down further, the Argon adds WiFi with an ESP32 from Espressif, the Boron brings LTE to the table with a ublox SARA-U260 module, and the Xenon ditches WiFi and Cellular, relying only on Bluetooth, but still retaining mesh networking. This segmentation makes sense; Particle wants you to buy a ton of the Xenon modules to build out your network, and use either the Argon or Boron module to connect to the outside world.

The form factor of the boards conforms to Adafruit Feather standard, a standard that’s good enough, and much better than gigantic Arduino shields with offset pins.

Of particular interest is the support for mesh networks. For IoT solutions (whatever they may be), mesh networking is nearly a necessity if you have a sufficient number of nodes or are covering a large enough area. The technology going into this mesh networking is called Particle Mesh, and is built on OpenThread. While it’s a little early to see Particle’s mesh networking in action, we’re really looking forward to a real-world implementation.

Preorder pricing for these boards sets the Argon module at $15, the Boron at $29, and the Xenon at $9. Shipping is due in July.

Returning A Lost Sheep To The NASA Fold

February 13, 2018 by Jenny List 48 Comments

About three weeks ago, we reported that a satellite enthusiast in Canada found an unexpected signal among his listening data. It was a satellite, and upon investigation it turned out to be NASA’s IMAGE satellite, presumed dead since a power failure in 2005 interrupted its mission to survey the Earth’s magnetosphere.

This story is old news then, they’ve found IMAGE, now move on. And indeed the initial excitement is past, and you might expect that to be it from the news cycle perspective. But this isn’t the Daily Mail, it’s Hackaday. And because we are interested in the details of stories like these it’s a fascinating read to take a look at NASA’s detailed timeline of the satellite’s discovery and subsequent recovery.

In it we read about the detective work that went into not simply identifying the probable source of the signals, but verifying that it was indeed IMAGE. Then we follow the various NASA personnel as they track the craft and receive telemetry from it. It seems they have a fully functional spacecraft with a fully charged battery reporting for duty, the lost sheep has well and truly returned to the fold!

At the time of writing they are preparing to issue commands to the craft, so with luck by the time you read this they will have resumed full control of it and there will be fresh exciting installments of the saga. Meanwhile you can read our report of the discovery here, and read about a previous satellite brought back from the dead.
