An image of a miniature diorama of Snow White and the Seven Dwarves. On the left is a more detailed 1/6 scale model with a tall, dark haired Snow White and dwarves with red caps and tan tunics. The image on the right is of a much smaller and less detailed set of miniatures. The figures's proportions are a little more uncanny and feel like a low budget Disney rip-off.

How Did They Make View-Master Slides?

The basics of producing a stereophotograph of real life places were well-established by the time the View-Master arrived, but producing images of imaginary scenes was a bit more involved. [View Master Travels and Peter Dibble] took a look at how the fairy tale and media tie-in reels may have been made.

Starting with simple dioramas, View-Master eventually developed an entire team to work on fairy tales. One of the most influential members was sculptor [Florence Thomas]. She was instrumental in updating many of the original fairy tale reels from small scale miniatures to 1/6 scale dioramas for the scenes. Unfortunately, the department was eventually cut and all the original miniatures thrown away.

Before VCRs, View-Master was the primary way people could interact with their favorite TV shows and movies when they weren’t being broadcast. TV shows could be photographed while in production in Hollywood with a stereo camera giving great visual detail. Some cartoon and movie reels were less engaging, having been made from promotional images, giving more of a paper cutout appearance rather than “real” 3D. In either case, many of these visual techniques have been lost with little documentation on how they were achieved.

We previously covered [View Master Travels and Peter Dibble]’s History of the View-Master and how you can digitize the disks for posterity.

Retrotechtacular: Julius Sumner Miller Breaks Lamps With Magnets

If you watched the Mickey Mouse Club way back when, you might remember Professor Wonderful, who was, in reality, physics professor [Julius Sumner Miller]. He also had his own show, “Why Is It So?” along with appearances on talk shows. We recently ran across one of the shows from 1962 where [Miller] uses electromagnets to break a lamp.

[Miller] moved to Australia, and this episode is from the Australian version of “Why Is It So?” As you might expect, given the topic, the professor covers Oersted and Faraday.

Retrotechtacular: Mr. Wizard Jams With IBM

You may not remember [Mr. Wizard], but he was a staple of nerd kids over a few decades, teaching science to kids via the magic of television. The Computer History Archives Project has a partially restored film of [Mr. Wizard] showing off sounds and noise on a state-of-the-art (for 1963) Tektronix 504 oscilloscope. He talks about noise and also shows the famous IBM mainframe rendition of the song “Daisy Bell.” You can see the video along with some extras below.

You might recall that the movie “2001: A Space Odyssey” paid homage to the IBM computer’s singing debut by having HAL 9000 sing the same song as it is being deactivated. The idea that HAL was IBM “minus one” has been repeatedly denied, but we still remain convinced.

Retrotechtacular: RCA Loses Fight To IBM

If you follow electronics history, few names were as ubiquitous as RCA, the Radio Corporation of America. Yet in modern times, the company is virtually forgotten for making large computers. [Computer History Archive Project] has a rare film from the 1970s (embedded below) explaining how RCA planned to become the number two supplier of business computers, presumably behind behemoth IBM. They had produced other large computers in the 1950s and 1960s, like the BIZMAC, the RCA 510, and the Spectra. But these new machines were their bid to eat away at IBM’s dominance in the field.

RCA had innovative ideas and arguably one of the first demand paging, virtual memory operating systems for mainframes. You can hope they were better at designing computers than they were at making commercials.

Retrotechtacular: Learning The Slide Rule The New Old Fashioned Way

Learning something on YouTube seems kind of modern. But if you are watching a 1957 instructional film about slide rules, it also seems old-fashioned. But Encyclopædia Britannica has a complete 30-minute training film, which, what it lacks in glitz, it makes up for in mathematical rigor.

We appreciated that it started out talking about numbers and significant figures instead of jumping right into the slide rule. One thing about the slide rule is that you have to sort of understand roughly what the answer is. So, on a rule, 2×3, 20×30, 20×3, and 0.2×300 are all the same operation.

You don’t actually get to the slide rule part for about seven minutes, but it is a good idea to watch the introductory part. The lecturer, [Dr. Havery E. White] shows a fifty-cent plastic rule and some larger ones, including a classroom demonstration model. We were a bit surprised that the prestigious Britannica wouldn’t have a bit better production values, but it is clear. Perhaps we are just spoiled by modern productions.

We love our slide rules. Maybe we are ready for the collapse of civilization and the need for advanced math with no computers. If you prefer reading something more modern, try this post. Our favorites, though, are the cylindrical ones that work the same, but have more digits.

How Cross-Channel Plumbing Fuelled The Allied March On Berlin

During World War II, as the Allies planned the invasion of Normandy, there was one major hurdle to overcome—logistics. In particular, planners needed to guarantee a solid supply of fuel to keep the mechanized army functional. Tanks, trucks, jeeps, and aircraft all drink petroleum at a prodigious rate. The challenge, then, was to figure out how to get fuel over to France in as great a quantity as possible.

War planners took a diverse approach. A bulk supply of fuel in jerry cans was produced to supply the initial invasion effort, while plans were made to capture port facilities that could handle deliveries from ocean-going tankers. Both had their limitations, so a third method was sought to back them up. Thus was born Operation Pluto—an innovative plan to simply lay fuel pipelines right across the English channel.

Jerry Seinfeld dressed up as a honey bee promoting his film Bee Movie.

Retrotechtacular: The $550K Video Conferencing System Used To Make Bee Movie

The modern office environment has shifted in recent years. Employees are routinely asked to collaborate with co-workers half way around the globe and be camera ready, or whatever passes for webcam ready, in order to telecommute when they are out of office. Every office laptop, tablet, or cell phone these days comes equipped with some sort of camera sensor capable of recording at HD resolution. Twenty years ago, that was not the case. Though tech conglomerates like HP had a different idea of teleconferencing to sell back in 2005 dubbed the Halo Collaboration Studio.

The Halo Studio was a collaboration between HP and Dreamworks that was used during the production of Bee Movie. Studio heads at Dreamworks thought it necessary to install the HP teleconferencing solution inside the New York office of Jerry Seinfeld, the writer of the film, as to allow him to avoid long trips to Dreamworks production offices in Los Angeles. According to the HP Halo Collaboration Studio brochure, “Halo actually pays for itself, not only by reducing travel costs, but also by encouraging higher productivity and stronger employee loyalty.” Certainly Dreamworks believed in that sales pitch for Bee Movie, because the upfront asking price left a bit of a sting.

Less of a singular machine, more of an entire dedicated room, the Halo Studio had a $550,000 asking price. It utilized three 1280×960 resolution plasma screens each fitted with a 720p broadcast camera and even included an “executive” table for six. The room lighting solution was also part of the package as the intent was to have all participants appear true to life size on the monitors. The system ran on a dedicated T3 fiber optic connection rated at 45 Mbps that connected to the proprietary Halo Video Exchange Network that gave customers access to 24×7 tech support for the small sum of $30,000 a month.
