The Dual In-Line Package And How It Got That Way

November 8, 2018 by Dan Maloney 68 Comments

For most of human history, our inventions and innovations have been at a scale that’s literally easy to grasp. From the largest cathedral to the finest pocket watch, everything that went into our constructions has been something we could see with our own eyes and manipulate with our hands. But in the middle of the 20th century, we started making really, really small stuff: semiconductors. For the first time, we were able to create mechanisms too small to be seen with the naked eye, and too fine to handle with our comparatively huge hands. We needed a way to scale these devices up somewhat to make them useful parts. In short, they needed to be packaged.

We know that the first commercially important integrated circuits were packaged in the now-familiar dual in-line package (DIP), the little black plastic millipedes that would crawl across circuit boards for the next 50 years. As useful and versatile as the DIP was, and for as successful as the package became, its design was anything but obvious. Let’s take a look at the dual in-line package and how it got that way.

How The Sony PlayStation Was Hacked

November 5, 2018 by Drew Littrell 34 Comments

Playgrounds were the comment sections of their day. Every weekday from exactly 1:17 PM until 1:43 PM there were swings to be swung, rumors to be spread, and debates to be settled by whomever was the loudest (some things never change). Allegiances were formed and battle lines were drawn based solely on what video game console you supported. It was this playground system that perpetuated the urban myths of the time.

For PlayStation fans there was the myth that you could save Aerith from her fate in Final Fantasy VII if you just cast the right spell, or the secret code in Tomb Raider that would let you see all of Lara Croft. There was the myth that no one could possibly copy a PlayStation game because all the bottoms of the discs were black. Even the very existence of the first PlayStation, the Super Nintendo PlayStation prototype, was an urban legend. The difference was that last one turned out to be true.

Let’s jump in and take a look at the cat and mouse game between modchip makers looking to defeat the original PlayStation’s copy protection, and Sony’s efforts to protect their castle.

Relativity Space’s Quest To 3D Print Entire Rockets

October 30, 2018 by Tom Nardi 27 Comments

While the jury is still out on 3D printing for the consumer market, there’s little question that it’s becoming a major part of next generation manufacturing. While we often think of 3D printing as a way to create highly customized one-off objects, that’s a conclusion largely based on how we as individuals use the technology. When you’re building something as complex as a rocket engine, the true advantage of 3D printing is the ability to not only rapidly iterate your design, but to produce objects with internal geometries that would be difficult if not impossible to create with traditional tooling.

So it’s no wonder that key “New Space” players like SpaceX and Blue Origin make use of 3D printed components in their vehicles. Even NASA has been dipping their proverbial toe in the additive manufacturing waters, testing printed parts for the Space Launch System’s RS-25 engine. It would be safe to say that from this point forward, most of our exploits off of the planet’s surface will involve additive manufacturing in some capacity.

But one of the latest players to enter the commercial spaceflight industry, Relativity Space, thinks we can take the concept even farther. Not content to just 3D print rocket components, founders Tim Ellis and Jordan Noone believe the entire rocket can be printed. Minus electrical components and a few parts which operate in extremely high stress environments such as inside the pump turbines, Relativity Space claims up to 95% of their rocket could eventually be produced with additive manufacturing.

If you think 3D printing a rocket sounds implausible, you aren’t alone. It’s a bold claim, so far the aerospace industry has only managed to print relatively small rocket engines; so printing an entire vehicle would be an exceptionally large leap in capability. But with talent pulled from major aerospace players, a recently inked deal for a 20 year lease on a test site at NASA’s Stennis Space Center, and access to the world’s largest metal 3D printer, they’re certainly going all in on the idea. Let’s take a look at what they’ve got planned.

Seth Molson Is Designing The Future, One Show At A Time

October 29, 2018 by Tom Nardi 27 Comments

From the banks of levers and steam gauges of 1927’s Metropolis to the multicolored jewels that the crew would knowingly tap on in the original Star Trek, the entertainment industry has always struggled with producing imagery of advanced technology. Whether constrained by budget or imagination, portrayals usually go in one of two directions: they either rely too heavily on contemporary technology, or else they go so far in the opposite direction that it borders on comical.

But it doesn’t always have to be that way. In fact, when technology is shown properly in film it often serves as inspiration for engineers. The portrayal of facial recognition and gesture control in Minority Report was so well done that it’s still referenced today, nearly 20 years after the film’s release. For all its faults, Star Trek is responsible for a number of “life imitating art” creations; such as early mobile phones bearing an unmistakable resemblance to the flip communicators issued to Starfleet personnel.

So when I saw the exceptional use of 3D printing in the Netflix reboot of Lost in Space, I felt it was something that needed to be pointed out. From the way the crew made use of printed parts to the printer’s control interface, everything felt very real. It took existing technology and pushed it forward in a way that was impressive while still being believable. It was the kind of portrayal of technology that modern tech-savvy audiences deserve.

It left such an impression that we decided to reach out to Seth Molson, the artist behind the user interfaces from Lost in Space, and try to gain a little insight from somebody who is fighting the good fight for technology in media. To learn how he creates his interfaces, the pitfalls he navigates, and how the expectations of the viewer have changed now that we all have a touch screen supercomputer in our pocket.

That Time Atari Cracked The Nintendo Entertainment System

October 22, 2018 by Drew Littrell 45 Comments

It was darkest hour for the video game industry following the holiday shopping season of 1982. The torrent of third party developed titles had flooded the home video game console market to the point of saturation. It incited a price war amongst retailers where new releases were dropped to 85% off MSRP after less than a month on the shelves. Mountains of warehouse inventory went unsold leaving a company like Atari choosing to dump the merchandise into the Chihuahuan desert rather than face the looming tax bill. As a result, the whole home video game industry receded seemingly overnight.

One company single-handedly revived video games to mainstream prominence. That company was Nintendo. They’re ostensibly seen as the “savior” of the video games industry, despite the fact that microcomputer games were still thriving (history tends to be written by the victors). Nevertheless their Nintendo Entertainment System (NES) was an innovative console featuring games with scrolling screens, arcade-like sprites. But the tactic they used to avoid repeating the 1983 collapse was to tightly control their market using the Nintendo Seal of Quality.

From the third party developer perspective, Nintendo’s Seal of Quality represented more than just another logo to throw on the box art. It represented what you could and couldn’t do with your business. Those third party licensing agreements dictated the types of games that could be made, the way the games were manufactured, the schedule on which the games shipped to retail, and even the number of games your company could make. From the customer side of things that seal stood for confidence in the product, and Nintendo would go to great lengths to ensure it did just that.

This is the story of how an Atari subsidiary company cracked the hardware security of the original Nintendo and started putting it into their unofficial cartridges.

ILLIAC Was HAL 9000’s Granddaddy

October 18, 2018 by Al Williams 42 Comments

Science fiction is usually couched in fact, and it’s fun to look at an iconic computer like HAL 9000 and trace the origins of this artificial intelligence gone wrong. You might be surprised to find that you can trace HAL’s origins to a computer built for the US Army in 1952.

If you are a fan of the novel and movie 2001: A Space Oddessy, you may recall that the HAL 9000 computer was “born” in Urbana, Illinois. Why pick such an odd location? Urbana is hardly a household name unless you know the Chicago area well. But Urbana has a place in real-life computer history. As the home of the University of Illinois at Urbana–Champaign, Urbana was known for producing a line of computers known as ILLIAC, several of which had historical significance. In particular, the ILLIAC IV was a dream of a supercomputer that — while not entirely successful — pointed the way for later supercomputers. Sometimes you learn more from failure than you do successes and at least one of the ILLIAC series is the poster child for that.

The Urbana story starts in the early 1950s. This was a time when the 1945 book “First Draft of a Report on the EDVAC” was sweeping through the country from its Princeton origins. This book outlined the design and construction of the Army computer that succeeded ENIAC. In it, Von Neumann proposed changes to EDVAC that would make it a stored program computer — that is, a computer that treats data and instructions the same.

Construction Cranes Versus Hurricanes

October 15, 2018 by Bryan Cockfield 14 Comments

When engineers are designing buildings, bridges, or other large construction projects, a lot of thought is given to the environment. Some of these considerations might seem obvious, like designing a skyscraper in San Francisco to tolerate earthquakes, building a stadium in New York City to hold up not only its own weight but the weight of several feet of snow on the roof, or constructing bridges in any coastal area to be able to tolerate salt spray. Not everything is this straightforward, though. Not only do the structures themselves have to tolerate the environmental conditions they are in, but the equipment that is used to build them must tolerate these conditions as well, specifically the large cranes that are often semi-permanently attached to their construction sites.

Perhaps the most extreme example of this in recent memory was during Typhoon Manghut as it hit Hong Kong. There were several large construction cranes that didn’t fare too well with the high winds. At least one toppled as a result and catching the free-spinning of another on video is more than enough to make you gasp. Other videos of construction cranes surfaced from this typhoon showing some concerning, but surprisingly well-designed, emergency operation of the same type of crane.
