Modernizing a Soviet-era LED Matrix

Used in everything from calculators to military hardware, the 3LS363A is an interesting piece of vintage hardware. With a resolution of 5 x 7 (plus a decimal point), the Soviet-made displays contain no electronics and are simply an array of 36 green LEDs. It’s not hard to drive one of them in a pinch, but [Dmitry Grinberg] thought this classic device deserved a bit better than the minimum.

He’s developed a small board that sits behind the 3LS363A and allows you to control it over I2C for a much more modern experience when working with these vintage displays. Powered by …read more

Top Secret Teardown Reveals Soviet Missile Secrets

Technology has moved at such a furious pace that what would have been most secret military technology a few decades ago is now surplus on eBay. Case in point: [msylvain59] picked up a Soviet-era K-13 IR seeker used to guide air-to-air missiles to their targets. Inside is a mechanical gyroscope turning at over 4,000 RPM, a filter made of germanium to block visible light, and a photoresistor. It’s sobering to think you can get all of this in a few small packages these days, if not integrated into one IC.

Fitting on top of a missile, the device isn’t that …read more

Spy Tech: How an Apollo Capsule Landed in Michigan after a Layover in the USSR

There’s an Apollo module on display in Michigan and its cold-war backstory is even more interesting than its space program origins.

Everyone who visits the Van Andel Museum Center in Grand Rapids, Michigan is sure to see the Apollo Command Module flanking the front entrance. Right now it’s being used as a different kind of capsule: as time capsule they’ll open in 2076 (the American tricentennial). If you look close though, this isn’t an actual Command Module but what they call a “boilerplate.”

Technically, these were mass simulators made cheaply for certain tests and training purposes. A full spacecraft costs …read more

Custom Built Vacuum Tube Cassette Player

As we’ve said many times here on Hackaday, it’s not our place to question why people make the things they make. There’s a legitimate need or utility for many of the projects we cover, no doubt about it. But there’s also a large number of them which are so convoluted that they border on absurd. Not that we love the crazy ones any less, in fact, we usually like those the best.

So when we saw this incredible modification to a Panasonic RN-404 microcassette recorder which replaces the audio hardware with a custom built vacuum tube amplifier, we didn’t bother …read more

Soviet Era Smoke Detector Torn Down, Revealing Plutonium

It’s widely known that a smoke detector is a good ionizing radiation source, as they contain a small amount of americium-241, a side product of nuclear reactors. But what about other sources? [Carl Willis] got hold of an old Soviet era smoke detector and decided to tear it down and see what was inside. This, as he found out, isn’t something you should do lightly, as the one he used ended up containing an interesting mix of radioactive materials, including small amounts of plutonium-239, uranium-237, neptunium-237 and a selection of others. In true hacker fashion, he detected these with a …read more

Soviet Portable Scopemeter Teardown

Browsing YouTube may prove to be your largest destroyer of productive time outside of Hackaday, once you have started looking at assorted Lincolnshire plumbers or young Ukrainians doing dangerous stunts it’s easy to lose an hour with very little to show for it. There is so much to divert our attention, it’s a wonder that any of us ever make anything!

So to ensure you lose a further quarter hour today, we’d like to bring you [Jesper Broe]’s demonstration and teardown of his latest oscilloscope. This might seem unpromising when we tell you it’s a single-trace model with a bandwidth …read more
