Soviet Scientific Calculator Gives Up Its Cold War-Era Secrets

July 17, 2021 by Dan Maloney 17 Comments

Say what you want about Soviet technology, but you’ve got to admit there was a certain style to Cold War-era electronics. Things were perhaps not as streamlined and sleek as their Western equivalents, but then again, just look at the Nixie tube craze to see where collectors and enthusiasts stand on that comparison.

One particularly interesting artifact from the later part of that era was the lovely Elektronika MK-52 “microcalculator”. [Paul Hoets] has done a careful but thorough teardown of a fine example of this late-80s machine. The programmable calculator was obviously geared toward scientific and engineering users, but [Paul] relates how later versions of it were also used by the financial community to root out banking fraud and even had built-in cryptographic functions, which made encrypting text easy.

[Paul] has put together a video of the teardown, detailing the mostly through-hole construction and the interesting use of a daughter-board, which appears to hold the high-voltage section needed to drive the 11-character VFD tube. The calculator appears to be very well cared for, and once reassembled looks like it would be up for another ride on a Soyuz, where once it served as a backup for landing calculations.

We love the look of this machine and appreciate [Paul]’s teardown and analysis. But you say that the Cyrillic keyboard has you stumped and you need a bilingual version of the MK-52? That’s not a problem.

As Chinese Wheels Touch Martian Soil And Indian Astronauts Walk Towards The Launch Pad, Can We Hope For Another Space Race?

If you were born in the 1960s or early 1970s, the chances are that somewhere in your childhood ambitions lay a desire to be an astronaut or cosmonaut. Once Yuri Gagarin had circled the Earth and Neil Armstrong had walked upon the Moon, millions of kids imagined that they too would one day climb into a space capsule and join that elite band of intrepid explorers. Anything seems possible when you are a five-year-old, but of course the reality remains that only the very fewest of us ever made it to space.

Did You Once Dream Of The Stars?

The picture may be a little different for the youth of a few decades later though, did kids in the ’90s dream of the stars? Probably not. So what changed as Shuttle and Mir crews were passing overhead?

The answer is that the Space Race between the USA and Soviet Union which had dominated extra-terrestrial exploration from the 1950s to the ’70s had by then cooled down, and impressive though the building of the International Space Station was, it lacked the ability to electrify the public in the way that Sputnik, Vostok, or Apollo had. It was immensely cool to people like us, but the general public were distracted by other things and their political leaders were no longer ready to approve money-no-object budgets. We’d done space, and aside from the occasional bright spot in the form of space telescopes or rovers trundling across Mars, that was it. The hit TV comedy series The Big Bang Theory even had a storyline that found comedy in one of its characters serving on a mission to the ISS and being completely ignored on his return.

A few years ago a Chinese friend at my then-hackerspace was genuinely surprised that I knew the name of Yang Liwei, the Shenzhou 5 astronaut and the first person launched by his country into space. He’s a national hero in China but not so much on the rainy edge of Europe, where the Chinese space programme for all its progress at the time about a decade after Yang’s mission had yet to make a splash beyond a few space watchers and enthusiasts in hackerspaces. But this might be beginning to change.

Russian Doomsday Radios Go Missing

December 15, 2020 by Al Williams 42 Comments

Normally we like hearing about old military gear going on the surplus market. But if you encounter some late-model Russian radio and crypto equipment for sale you might want to make sure it isn’t hot (English translation). If you prefer not picking through the machine translation to English, the BBC also has a good write-up.

The Russians maintain four large planes set up as flying command and control bunkers in case of nuclear war — so-called “doomsday planes.” Like the U.S. ABNBC (better known as Looking Glass) fleet, the planes can provide the President or other senior leaders a complete command capability while in flight. As you might expect, the radios and gear on the plane are highly classified.

Electric Dreams Help Cows Survive The Desert Of The Real

December 3, 2019 by Tom Nardi 64 Comments

Pictures of a cow wearing a pair of comically oversized virtual reality goggles recently spread like wildfire over social media, and even the major news outlets eventually picked it up. Why not? Nobody wants to read about geopolitical turmoil over the holidays, and this story was precisely the sort of lighthearted “news” people would, if you can forgive the pun, gobble up.

But since you’re reading Hackaday, these images probably left you with more questions than answers. Who made the hardware, what software is it running, and of course, why does a cow need VR? Unfortunately, the answers to the more technical questions aren’t exactly forthcoming. Even tracking the story back to the official press release from the Ministry of Agriculture and Food of the Moscow Region doesn’t tell us much more than we can gather from the image itself.

But it does at least explain why somebody went through the trouble of making a custom bovine VR rig: calm cows produce more milk. These VR goggles, should they pass their testing and actually be adopted by the Russian dairy industry, will be the newest addition to a list of cow-calming hardware devices that farmers have been using for decades to get the most out of their herds.

Plan Ahead: Roaming Charges Are A Killer

November 9, 2019 by Al Williams 20 Comments

As the world gets more connected and computerized, it is easy to have an unintended consequence pop up and bite you. Especially because, so much of the time, today, things just work. The days of fretting over how to connect two computers, or how to store reasonable amounts of data are gone. Most of us never have to sift through assembly language programs finding three extra bytes to add a feature. Some Russian scientists recently found out about unintended consequences the hard way.

In the United States, the Eagle was long on the endangered species list, but apparently they have a similar problem in Russia. Scientists put a tracker on some migrating eagles in southern Russia and Kazakhstan. A few decades ago, this would have been a big technical challenge, but now you just use cellular technology and have the tracker text its location, right?

Echos Of The Cold War: Nuclear-Powered Missiles Have Been Tried Before

August 20, 2019 by Tom Nardi 63 Comments

On August 8th, an experimental nuclear device exploded at a military test facility in Nyonoksa, Russia. Thirty kilometers away, radiation levels in the city of Severodvinsk reportedly peaked at twenty times normal levels for the span of a few hours. Rumors began circulating about the severity of the event, and conflicting reports regarding forced evacuations of residents from nearby villages had some media outlets drawing comparisons with the Soviet Union’s handling of the Chernobyl disaster.

Today, there remain more questions than answers surrounding what happened at the Nyonoksa facility. It’s still unclear how many people were killed or injured in the explosion, or what the next steps are for the Russian government in terms of environmental cleanup at the coastal site. The exceptionally vague explanation given by state nuclear agency Rosatom saying that the explosion “occurred during the period of work related to the engineering and technical support of isotopic power sources in a liquid propulsion system”, has done little to assuage concerns.

The consensus of global intelligence agencies is that the test was likely part of Russia’s program to develop the 9M730 Burevestnik nuclear-powered cruise missile. Better known by its NATO designation SSC-X-9 Skyfall, the missile is said to offer virtually unlimited flight range and endurance. In theory the missile could remain airborne indefinitely, ready to divert to its intended target at a moment’s notice. An effectively unlimited range also means it could take whatever unpredictable or circuitous route necessary to best avoid the air defenses of the target nation. All while traveling at near-hypersonic speeds that make interception exceptionally difficult.

Such incredible claims might sound like saber rattling, or perhaps even something out of science fiction. But in reality, the basic technology for a nuclear-powered missile was developed and successfully tested nearly sixty years ago. Let’s take a look at this relic of the Cold War, and find out how Russia may be working to resolve some of the issues that lead to it being abandoned.

Russian EBike Goes Everywhere, Possibly Legal

July 28, 2019 by Bryan Cockfield 54 Comments

Electric bikes may be taking the world by storm, but the world itself doesn’t have a single way of regulating ebikes’ use on public roads. Whether or not your ebike is legal to ride on the street or sidewalk where you live depends mostly on… where you live. If you’re lucky enough to live in a place where a bicycle is legally defined as having fewer than four wheels and capable of being powered by a human, though, this interesting bike from Russia might be the best homemade ebike we’ve ever seen. (Video embedded below the break.)

While some of the details of this build might be lost on those of us who do not know any Slavic languages, the video itself shows off the features of this electric vehicle build quite well. It has a custom built frame with two wheels up front, each with its own independent suspension, allowing it to traverse extremely rough terrain with ease even a mountain bike might not be able to achieve. It seems to be powered by a relatively simple rear hub in the single rear wheel, and can probably achieve speeds in the 20 km/h range while holding one passenger and possibly some cargo.

The impressive part of this build isn’t so much the electrification, but rather the suspension components. Anyone looking for an offroad vehicle may be able to take a bit of inspiration from this build. If you’re more interested in the drivetrain, there are plenty of other vehicles that use unique electric drivetrains to check out like this electric boat. And, if you happen to know Russian and see some other interesting details in this build that the native English speakers around here may have missed, leave them in the comments for us.
