FAQ
Q) Why are there comments from a week ago when this video has just gone live today?
A) Patrons usually have early access to videos. I'll show the first version of a video on Patreon and often the feedback I get results in a video going through further revisions to improve it. e.g. Fix audio issues, clarify points, add extra footage or cut extraneous things out. The video that goes live on youtube is the final version.

[@Elektronijaenis]

I was going to come give the same translation here. :D About the uses of this kind of technology: As a kid, I remember a school trip to a candy factory (Fazer). First thing when we got there was guide us to an auditorium where we were shown a big corporate slide show about the company. That slideshow was done on a bunch of projectors. I remember the images to fade to other images and the images on the screen changed maybe in 6 separate parts. I believe the image fades were made by fading the light on one projector out and another in at the same time... So it was probably at least twelve separate slide projectors there sychronized to one giant slide show. The soundtrack was continous, so the show probably wasn't using this kind of projectors though. (That was maybe late 80's.) Much later at work one of our offices had an auditorium that had a bunch of slide projectors installed. That was early 2000's and by that time they were not used anymore (They were practically only collecting dust at that time.) I wish I had examined those a then. The bureau I work for moved out of that building years ago. So... While I have no experience about that particular slide projector, maybe these experiences will shed some light to how that kind of projectors might have been used back in the day. And maybe "slide projector multimedia" was more common in Finland than elsewhere.

These things remind me of when I was a kid, we would watch filmstrips in school, and they came with cassettes that had the narration on them. There'd be a beep to tell the teacher, or more often a student who'd been assigned to do it, to advance the film to the next frame. It was a coveted assignment, and I was very good at it. I can still remember my Luddite-like fury and heartbreak when an automated filmstrip projector that could hear the beep and advance automatically came along and put me out of a job. This device is like that, except mechanically baroque enough that I would have forgiven it. :)

Fantastic! I was not aware that anything like this existed. In 1989, for Hewlett-Packard's 50th Anniversary (in Australia), we were still using slide sets with recorded soundtrack, although there were multiple projectors and they were cued to the soundtrack. Somewhere in the garage I still have videotapes of those presentations... This is a brilliant attempt at replicating that function around twenty years earlier, when most of use were using a standard slide projector and providing live audio commentary to the suffering audience.

[@SierraLimaOscar]

Ahh, the magic of Multivision! I produced a few of those for tourist destinations in Yugoslavia. The Kodak Carousel slide projectors cost an arm and a leg and there were thousands scattered around corporate boardrooms and museums. I remember the first show I did (4 projectors! 😂)the recording would only move the slide forward and dim the bulb to do a cross dissolve with the other projector. So if the carousel skipped a slide the whole show was out of wack. Later on we used a digital system from an Austrian company (Stumpfl) that kept track of the positions of the slides. Good times.

It’s amazing how far media technology has come in a relatively short time.

I don't think future people will look upon current technology in the same way we look at old technology like this. Now that everything's digital I don't think we'll see as much fundamental change. As an example going from CDs to MP3 files enables a shift in usage habits while going from floppy disks to flash media doesn't. We use flash drives and SD cards basically the same way we used floppy disks back in the day.

[@sketchesofpayne]

It's hard to imagine what could be more advanced/convenient than cloud storage that you can access or share wirelessly with anyone on devices that fit in our pockets. We've sort of already arrived at peak media and file access, storage, and sharing. You can give someone access to your Dropbox or Google Drive or share movies with them via a PLEX server or video you've taken with your phone on any number of social media sharing apps. If all else fails you put it on a USB thumb drive or SD flash memory card and give it to them.

WOW! This brings back memories! I worked for Pacific Gas & Electric (PG&E) in San Francisco from 1984-1989 and they used this system to train power plant workers on “Lock Out, Tag Out”, Power Generation Steam and Water Cycle, Electrical Distribution systems, etc. The squeal noise is the automatic focus compensation. YOU set the focus for the first slide and the machine tries to maintain that fir the other ones. As each slide is projected, heat from the lamp causes the slide to expand and flex. The machine has a detector that sees the slide flex and triggers a re-focus of the slide. That’s why you hear the focus motor squeal and the slide refocuses a few seconds after it’s been displayed. It’s quite a neat feature! Great video!

[@DavePurz]

Our projector had a terrible “Wow” problem. They’d play the sound of a transformer humming and the 60 cycles varied +/- 5! With the sick transformer sound in the background they’d say, “Recognize that sound?… That’s the sound of power!” Ha Ha Ha! The training courses were professionally produced.

The trick is that when they take you into the closed room to discuss the timeshare you just need to be brutally honest and tell them you're just there for the free trip to Las Vegas and the free show or horse back ride (or whatever else was offered as the hook) and that you don't want to waste any more of their time because you have zero interest in buying a timeshare. The trick is that by the time your done with the presentation it is usually too late to take advantage of the free thing they were offering so they rarely had to buy tickets or pay for free entertainment they had promised.

Fascinating. One of my first projects was to put together a slide presentation with accompanying audio and I recall the huge effort required to make just a small change in one of Kodak’s (linear of course) tape-based systems. This system would have have enabled the creator to make a last minute change or to add/subtract content. I’m pretty sure that most users of PowerPoint are completely unaware of the “slide by slide” audio recording feature that exists in the product today!

[@telocho]

When the film heats up when projected, it plops in its frame since it becomes larger due to the heat. The autofocus senses that and re-focuses and causing the squeel. Auofocus works by a small incandescent bulb (like a bicycle lamp) under the slide where the lens is, reflecting to an eletronic eye, and placed so that it is not sensible to the light from the projector bulb. Professional slide frames have a glass substrate to avoid this refocussing for a more professional presentation.

I was thinking the same but then started to wonder: is it able to reset itself back to the beginning of the slide set without operator intervention?

[@SimonPain]

True. Maybe not then. I wonder if they did a carousel for it?

In around 1971 I attended a "multi-media" presentation designed to enthrall tourists in San Francisco's Ghirardelli Square. We were on the top floor of a huge brick building in a very long narrow room. There were perhaps 80-100 of us facing one of the long white walls that acted as screens. Somewhere I could hear at least 30 slide projectors whirring and clicking while the audience watched. Billed as "The experience of the future" I was not impressed as various images and voice-overs assailed our senses. I could not understand how they coordinated the audio with so many slide projectors. I now believe its was a row of these machines that were in use. Mystery solved...I think. Thanks for the video.

I enjoy your channel and this segment was the best ever. I had no idea that these things even existed. From 1987 to 1997 I worked with an excellent photographer who did multi-media presentations of his work for civic groups and women's clubs. He has passed away but I have fond memories of our work together. He used two projectors with a sound system I designed using Crown Audio amplifiers in a small rack with a Crown preamp and a Tascam four track reel to reel in a custom flight case. The speaker system was two Boston Acoustics speakers and a powered subwoofer. The sound tracks were stereo with a blank channel and and a tone channel for the projector cues. We ended up doing three major fifty minute shows and several shorter shows which he presented dozens of times. I started with razor editing and later progressed to mixer based sound editing. Aside from the hours and hours spent listening to Yanni music it was a great experience. Seeing the other technology which was available at the time I can see why he sought a higher quality way to go. Keep up the good work!

My dad had a 3M projector exactly like that except no sound. I remember as a teenager seeing his Vietnam war photos on slides. He’s since transferred them all to digital. But man, seeing that projector I can really remember the clackety clack of the advance mechanism and the heavy solid feel of the metal case.

[@GoshdarnCat]

First of all, greetings to Matti from another Finn! I once got a very well packed bunch of vinyl records from someone here in Finland - can't remember the name any more but judging from the packaging, I wouldn't be surprised if it was you :) When I was in junior high school between 1985-1988, we had very similar looking slide projector in one classroom. However, it didn't save the sound on the slide holders like this one but it was connected to a separate reel to reel player instead. I believe there were some educational slide sets with pre-recorded tapes that were shown to us. The setup looked very archaic already back then and it wasn't used much. Also, the fan noise drowned pretty much the sound on the tape. And yes, the guy in the makeup is a rather good imitation of Diamond Dave, or David Lee Roth who had left Van Halen for a solo career and appeared like this on his first solo album "Eat 'em And Smile" in 1986.

I saw these in an old set of encyclopedias given away for free outside a thrift store (along with a book promoting eugenics from the 1920's), and I always was curious about them, so thanks for sharing this neat bit of tech I always wanted to find out more about.

[@LukasDzunko]

That squeaky sound seems like auto-focus. We had similar projector (without sound) and it used several bulbs and sensors to identify position of film and adjust focus automatically. Slide holders are not perfectly matched and it is possible to insert them in opposite direction. This is causing small variation in film placement (in light path) and causing picture to go out of focus. Automatic system can identify this small variation and adapt focus if necessary ... that sound seems like motor is slipping when trying to move focus on lens. Another possibility is that one of sensor is obscured by dust and / or detection bulb is not working and it is trying to move focus in one direction hitting limits of lens .... btw. it was really paint to present with projector without auto-focus. It was either all pictures a bit blurred or operator was adjusting focus on each slide ...

[@erwintimmerman6466]

My mother had a standard mechanical slide projector that looked like this thing, just a bit smaller. It also had problems with slides being stuck in the external position all the time, even when it wasn't cold. Later I had one of those rotational magazine projectors that very regularly suffered stuck slides as well. So it's actually a quite common problem amongst slide projectors.

[@Meton12765]

Yeah, Finns and wood. Tends to escalate fast.

[@worldtraveler930]

[@randyariddle]

One of the main attractions of this for a business would be the ability to rearrange and switch out slides. I could see this being used for different versions of a sales talk given to different audiences or to run a "draft" of a show that would be professionally recorded later for managers.

My Dad who was in life insurance had a similar piece of equipment that did pre-done shows. It was built around a Kodak Carousel Slide Projector and a cassette player. The slides were done by a graphics house (this was before Powerpoint) and loaded into a tray. A tape was prepared with the appropriate narration and a pulse tone to advance the projector. Through a system of lenses and mirrors was projected on a screen from inside. It was used on a tabletop for small groups. It was branded as a Roadshow, but I can't seem to find anything about it. Sadly, in my youth I took the thing apart to get the slide projector and trashed the rest of it.

[@mishmashmedley]

this all reminds me of school. I was one of "The AV Nerds" who would run the film projector in class. My school had an array of 60's and 70's era tech that the school was using up into the 90s (may still be for all I know - if it's still functioning). I recall running the slide projector along with a tape recording and when I heard the 'ding' sound, I advanced the slide - much like those old kiddie record-and-book combinations. All fun stuff, I miss messing with it all.

I remember seeing a lot of sound illustraded slide presentatons on machinery and chemical plant processes like that as a kid at Leipzig trade fair in the 70ies/early 80ies until video became more common. Mostly backlit screens. Pretty amazing back then - slide shows with holiday pictures where things to bore friends and family with these times. :-)

Once upon a time, the hospital I worked for had a Carousel system that synced multiple slide projectors with a cassette and provided a seamless presentation that was almost as good as a film. I was in Boston MA around 1979 and they had the same system at Fanuell hall celebrating 250 years of Boston and I think it must have had over 50 slide projectors synced to sound. It was a really moving presentation and again, almost as good as a video would have been. One of the audio comments in that presentation was two proper Bostonian matrons discussing why they were there and one said, "I came to get scrod." (A type of fish) The other lady said, "I didn't know there was a past tense." Floored me as I had always heard Boston was very prim and proper! :-)

I bought a slide storage container, like a mini suitcase, to store all my slides in. Turns out it was full of slides. I ran them through my projector, and about a third of of some dude's house, with visitors, etc. a third are of the outside, with a large garden live steam railroad (quite amazing, in fact), and the last third are photos of the dude's TV, showing shots of the various Apollo missions! He's got several missions, including Apollo 11, IIRC. They aren't all the greatest, esp. since sometimes he got mostly the "scan lines" between frames, and the photo isn't all screen. But still, this guy took the effort to make "screen caps" of various Apollo missions as they happened. My original plan was to toss all the slides, but I kept the railroad and Apollo slides. Very cool stuff. I can see why people would buy these things. You never know what you'll find! My plan is to buy an adapter for my camera, to "scan" in all my slides, including these ones. but that's been my plan for the past 15 years! Still haven't done it. I may have some free time next year. Maybe then ;-)

My grandparents were very well-traveled people, and naturally I aspired to travel around the world like they did. In 2007, I began working in the Middle East, and was able to travel to Europe, Japan, and to The Philippines...all places they had visited and produced caddy upon caddy of slides. Of course I had taken pictures with my digital camera, but I was able to create slideshows that could easily be presented on almost any television from my iPod. My grandparents were astonished at not only my adventures, but how technology had progressed.
