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.
Hackaday Links: June 14, 2026
Times are tough out there, and many are starting to feel the pressure at the grocery store checkout line or the gas pump. But whenever you start to worry about affording life’s necessities, take comfort in the knowledge that somebody is so flush with cash that on Friday they decided to treat themselves and spend $3 million for a sealed copy of Super Mario Bros for the Nintendo Entertainment System.
Although we’re not going to say it necessarily justifies the insane price — a new record for the most ever paid for a video game, incidentally — Heritage Auctions does note in their press release that this is an exceptionally rare version of what’s admittedly one of the most iconic pieces of software ever produced. This is only one of three copies of this particular variant known to exist, which Nintendo apparently distributed to test markets in the United States ahead of the game’s official 1985 release.
In slightly more modern gaming news, Asha Sharma, the new head of Microsoft’s Xbox division, has been making some big swings to try and get Microsoft’s gaming division back on track after years of declining sales. As part of that effort, she recently penned an article detailing some of the challenges the company is facing, which includes some interesting hardware details.
According to the blog post, she claims that in February, the cost of memory and storage components for the Xbox console had doubled compared to the previous year. But those numbers have jumped again, and by the time the holidays roll around, she expects they’ll be paying five times what they did in 2024. That’s bad news for anyone looking to put an Xbox under the tree come Christmas, but even worse news as the company works on the console’s successor. Considering that today’s hardware from Sony and Microsoft can already set you back $700 USD depending on which version you get, it seems like we’re approaching a point where gaming consoles could price themselves out of the market.
Patterns Everywhere
I studied physics in college, and I’m always surprised how fundamental some of the concepts are. Take waves for example. You really wouldn’t expect the same underlying concept to be at work on surface of a pond, the string of a guitar, light passing through two slits, and then in the probabilistic behavior of electrons orbiting inside nuclei. But here we are, in a world filled with wave-like phenomena.
What little control theory I know, I’ve learned in the school of hard knocks. But it’s equally amazing that the same basic concepts govern the tuning of car shock absorbers, PID controllers, active audio filters, and other more complex systems where feedback matters. Crucial in all of these systems is the judicious balance of amplification and damping.
And last week on vacation, learning to drive a covered wagon pulled by a heavy draft horse, I saw the same patterns again. The horse likes to pull, and when the wagon comes over the crest of the top of a hill, it starts to roll forward into his harness, pushing him from behind. This makes the horse uneasy, and he slows down, the wagon pushes him harder, and positive feedback gets out of control.
The man who was teaching me to drive the wagon said, “it’s not like a car” in that you don’t tap the brakes to slow down and then let go. Rather, you hold on the brakes for a lot longer than you think is necessary – until the horse tells you that he feels like pulling again – and then you let up only a tiny bit at a time. Otherwise, you end up in the under-damped case, where you let the wagon go too much, it slows the horse, you slam the brakes, the horse pulls hard, and you let up on the brakes, and the cycle continues anew.
What he meant by “not like a car” was that the brakes aren’t just slowing down the wagon, they’re adding damping to keep the horse-wagon system from oscillating. Once that clicked in my mind, everything was smooth sailing. After a couple of days, I even started adding some feed-forward to my mental PID controller, letting the brakes go a little bit more when the horse was approaching the bottom of a hill, and he obviously wanted to pick up a little more speed before the grade ahead.
The horse seemed happy that I was finally getting it, but I don’t think he had any understanding of tuning PID loops. He did have me pondering, on a long stretch of rolling hills on a summer morning, if there were a good minimal set of patterns that explained a maximal breadth of phenomena. I’m starting with the physics of waves and the control of feedback systems, but what’s next?
Hackaday Podcast Ep 373: GPS, Danger In Space, And Robby The Robot
Last week, Elliot got his foot stepped on by a 1.5 metric ton draft horse, and boy is he glad to be back to the relative safety of podcasting! Joining him today is Jenny List, no stranger to farm life, who has been trodden by a cow. It’s going to be one of those podcasts, folks.
Another thing the two hosts have in common is a love for the mystery of the numbers station. But did you know that GPS satellites, for the last 20 years, have broadcast literally millions of secret messages to everyone on the earth with a receiver? After that bombshell, we have an ATtiny85 emulating an 8080, a primer on how to embed magnets in 3D prints, definitive proof that more than one cassette mechanism is still being manufactured, and a look at what makes home automation enthusiasts tick.
Check out the links below if you want to follow along, and as always, tell us what you think about this episode in the comments!

This Week In Security: Microsoft On Microsoft, Register Your Domains, Linux On ARM, And FreeBSD Joins The File Cache Club
Supply chain attacks continue, with Microsoft’s own open source Azure repositories being automatically disabled by GitHub following a compromise of the packages by the Miasma worm.
OpenSourceMalware reports that the infection resulted in 73 Microsoft-related package repositories being flagged and taken offline in a little over a minute by the GitHub automated security system, with over 40 repositories being related to Azure and the rest distributed across the Microsoft organization.
The center of the infection appears to be the Microsoft Durabletask package, which was previously compromised in May and used to push infected packages to PyPi. Considering that all of the supply chain worms also steal credentials for every service they can find in the build or developer environment they infect, it seems likely that credentials stolen in the original attack were never properly disabled.
Disabling the repositories can help stem the infected packages and GitHub actions from spreading and infecting more organizations, but of course any build processes depending on those packages will not function. In May, the Durabletask package showed over 400,000 downloads per month.
The OpenSourceMalware report includes a full list of the impacted repositories.
Microsoft Fixes GitHub Token Exploit
Microsoft has finally fixed a bug in GitHub which could steal a GitHub authentication token with access to all of an accounts repositories via the embedded web-based VSCode editor which is part of GitHub itself.
Ammar Askar discovered the bug and discusses it on their blog; by manipulating the sandboxed VS Code into treating an embedded web view as user keyboard strokes, it is possible to to cause it to install a VS Code extension which is then used to exfiltrate the GitHub authentication tokens of the user using the embedded VS Code instance.
