Retrotechtacular: HGTV, The Place For Everything CES 1996

January 8, 2019 by 8 Comments

It’s January, and that means it’s time once again for the Consumer Electronics Show. CES is the place where electronic manufacturers from all across the globe to show off their future products and make promises they probably can’t keep. Of course there is no better indicator of a company’s future than looking at the past, and thanks to [Home & Garden Television] we have a comprehensive look at what CES was twenty three years ago. The cable channel aired a special, “Plugged In with Wil Shriner”, covering CES 1996 and it is certainly illuminating to see in hindsight. Plus it even comes complete with “cable money” tier mid 90s motion graphics.

Over on YouTube, user [videoholic] has uploaded the HGTV CES ’96 special into five separate segments (links provided below). Some of the highlights include:

Part 1 – Home Video

  • Canon introduces IR eye tracking (akin to the New 3DS) in their camcorder line
  • Dual recording VCR from Sharp on one VHS tape provided you can fix the tracking with the remote.
  • The term “I triple E 1394” may just have been said for the first (and last) time ever on cable television.

Part 2 – Audio

  • A digital alarm clock from Oregon Scientific (called the Time Machine) that will tell you the weather.
  • Magellan thought, “Who needs a cell phone when you can have a satellite phone for $8000”.
  • Soundtube, the fashionable beer cozy for your gigantic speakers as seen on MTV Beach House.

Part 3 – Games & Multimedia

  • Noise Cancellation Technologies INC wanted to turn your cars headliner into a big ol’ speaker.
  • Cyber Pong promised online multiplayer a full decade before Rockstar’s Table Tennis on Xbox 360.
  • The Simpsons Cartoon Studio helps create fan fiction on multimedia CD-ROM.

Part 4 – Home & Office

  • Compaq’s PC keyboard with an integrated fax machine.
  • Norris Communication’s handheld voice recorder full of flash memory to offload to your PDA.
  • Crestron’s idea of home automation involved a touchscreen to operate a light switch (some things never change).

Part 5 – Digital Video

Retrotechtacular: Remembering Radio Shack P-Box Kits

December 14, 2018 by 84 Comments

If you are under a certain age, you probably associate Radio Shack with cellphones. While Radio Shack never gave us access to the variety and economy of parts we have today, they did have one thing that I wish we could get again: P-Box kits. The obvious questions are: What’s a P-Box and why do I want one? But the kit wasn’t to make a P-Box. P-Box was the kind of box the kit came in. It was like a piece of perfboard, but made of plastic, built into a plastic box. So you bought the kit — which might be a radio or a metal detector — opened the box and then built the kit using the box as the chassis.

The perfboard was pretty coarse, too, because the components were all big discrete components. There was at least one that had an IC, but that came premounted on a PC board that you treated like a big component. One of my favorites was a three-transistor regenerative shortwave receiver. In those days, you could pick up a lot of stations on shortwave and it was one of the best ways at the time to learn more about the world.

On the left, you can see a picture of the radio from the 1975 catalog. You might think $7.95 is crazy cheap, but that was at least a tank full of gas or four movie tickets in those days, and most of us didn’t have a lot of money as kids, so you probably saved your allowance for a few weeks, did chores, or delivered papers to make $8.

CRT Monitor Recyling Center

Retrotechtacular: Some Of The Last CRTs From The Factory Floor

November 30, 2018 by 41 Comments

It seems crazy having to explain what a piece of technology was like to someone who is barely fifteen years your junior, but yet we have reached that point when it comes to CRTs. There may still be remnants of CRT televisions and monitors left out in the wild, however, the chances that a kid preparing to enter high school has encountered one is slim. While there may be no substitute for the real thing, there is this raw video from [Glenn] who shared his tour of the Sony Trinitron assembly line in the early 2000s. Sony Trinitron Television

Sony Electronics’ cathode ray tube manufacturing facility was located alongside headquarters in Rancho Bernado, CA. The facility was shuttered in 2006 when Sony transitioned wholly onto digital displays like the flat-panel LCD line of Bravia televisions. [Glenn]’s video shows that the manufacturing process was almost entirely automated from end to end. A point that was made even more clear with the distinct lack of human beings in the video.

The Trinitron line of televisions first appeared in 1968. At a time where most manufacturer’s were offering black and white picture tubes, Sony’s Trinitron line was in color. That name carried through until the end when it was retired alongside tube televisions themselves. Sony’s focus on technological innovation (and proprietary media formats) made them a giant in the world of consumer electronics for over forty years in the United States, but in the transition to a digital world saw them seeding market share to their competitors.

A quick word of warning as the video below was shot directly on Sony’s factory floor so the machinery is quite loud. Viewers may want to reduce the volume prior to pressing play.

Retrotechtacular: Disposing Of Sodium, 1947-Style

October 3, 2018 by 55 Comments

A high school friend once related the story about how his father, a chemist for an environmental waste concern, disposed of a problematic quantity of metallic sodium by dumping it into one of the more polluted rivers in southern New England. Despite the fact that the local residents were used to seeing all manner of noxious hijinx in the river, the resulting explosion was supposedly enough to warrant a call to the police and an expeditious retreat back to the labs. It was a good story, but not especially believable back in the day.

After seeing this video of how the War Department dealt with surplus sodium in 1947, I’m not so sure. I had always known how reactive sodium is, ever since demonstrations in chemistry class where a flake of the soft gray metal would dance about in a petri dish full of water and eventually light up for a few exciting seconds. The way the US government decided to dispose of 20 tons of sodium was another thing altogether. The metal was surplus war production, probably used in incendiary bombs and in the production of aluminum for airplanes. No longer willing to stockpile it, the government tried to interest industry in the metal, but to no avail due to the hazard and expense of shipping the stuff. Sadly (and as was often the case in those days), they just decided to dump it.

Retrotechtacular: The Iron Giants That Built The Jet Age

September 1, 2018 by 45 Comments

In the closing months of World War II, the Axis and the Allies were throwing everything they had at each other. The tide was turning to the Allies’ favor, but the Germans were showing a surprising resilience, at least in terms of replacing downed fighter and bomber aircraft. When the Allies examined the wreckage of these planes, they discovered the disturbing truth: the planes contained large pieces forged from single billets of metal, which suggested a manufacturing capability none of the Allies possessed and which allowed the Germans to quickly and cheaply make better and faster planes.

When the war was over, the Allies went looking for the tools the Germans had used to make their planes, and found massive closed-die forging presses that could squeeze parts out of aluminum and magnesium alloys in a single step. The Soviets carted off a 30,000 ton machine, while the Americans went home with a shipload of smaller presses and the knowledge that the Russians had an edge over them. Thus began the Heavy Press Program, an ultimately successful attempt by the US military to close a huge gap in strategic manufacturing capabilities that [Machine Thinking] details in the excellent video below.

One doesn’t instantly equate monstrous machines such as the Mesta 50,000-ton press, over nine stories tall with half of it buried underground and attached directly to bedrock, with airplane manufacture. But without it and similar machines that came from the program, planes from the B-52 to the Boeing 747 would have been impossible to build. And this isn’t dead technology by any means; sold to Alcoa in 1982 after having been operated by them for decades, the “Fifty” recently got a $100 makeover after cracks appeared in some castings, and the press and its retro-brethren are still squeezing out parts for fighters as recent as the F-35.

Dawn Of The First Digital Camera

August 13, 2018 by 71 Comments

Technology vanishes. It either succeeds and becomes ubiquitous or fails. For example, there was a time when networking and multimedia were computer buzzwords. Now they are just how computers work. On the other hand, when was the last time you thought about using a CueCat barcode reader to scan an advertisement? Then there are the things that have their time and vanish, like pagers. It is hard to decide which category digital cameras fall into. They are being absorbed into our phones and disappearing as a separate category for most consumers. But have you ever wondered about the first digital camera? The story isn’t what you would probably guess.

The first digital camera I ever had was a Sony that took a floppy disk. Surely that was the first, right? Turns out, no. There were some very early attempts that didn’t really have the technology to make them work. The Jet Propulsion Laboratory was using analog electronic imaging as early as 1961 (they had been developing film on the moon but certainly need a better way). A TI engineer even patented the basic outline of an electronic camera in 1972, but it wasn’t strictly digital. None of these bore any practical fruit, especially relative to digital technology. It would take Eastman Kodak to create a portable digital camera, even though they were not the first to commercialize the technology.

Retrotechtacular: Constructing A Car Engine

Oxford is a city world-famous for its university, and is a must-see stop on the itinerary of many a tourist to the United Kingdom. It features mediaeval architecture, unspoilt meadows, two idylic rivers, and a car plant. That’s the part the guide books don’t tell you, if you drive a BMW Mini there is every chance that it was built in a shiny new factory on the outskirts of the historic tourist destination.

The origins of the Mini factory lie over the road on a site that now houses a science park but was once the location of the Morris Motors plant, at one time Britain’s largest carmaker. In the 1930s they featured in a British Pathé documentary film which we’ve placed below the break, part of a series on industry in which the production of an internal combustion engine was examined in great detail. The music and narration is charmingly of its time, but the film itself is not only a fascinating look inside a factory of over eight decades ago, but also an insight into engine manufacture that remains relevant today even if the engine itself bears little resemblance to the lump in your motor today.

Morris produced a range of run-of-the-mill saloon cars in this period, and their typical power unit was one of the four-cylinder engines from the film. It’s a sidevalve design with a three-bearing crank, and it lacks innovations such as bore liners. The metallurgy and lubrication in these engines was not to the same standard as an engine of today, so a prewar Morris owner would not have expected to see the same longevity you’d expect from your daily.
