Another short sequence showing my 32-line televisor in action. The singer is the danish actor Buster Larsen singing 'hip hurray for old Denmark' in about 1960.
Again this was filmed off screen using a Sony Digital Video Camera with 'slow shutter', the picture frequency of the televisor being 12 1/2 Hz. The picture consists of 32 vertical lines each consisting of 64 points for picture + 6 points of black (32x70). The programme is DVD run through a Pal625/Baird32 signals converter I build in 1999. You can see it in the video. The televisor is scanning from top left to buttom right - this being the opposite of the original Baird Television System developed by John Logie Baird.

"Technology Connections" channel linked me here from their series on mechanical televisions and how they worked. This is really cool, I like your setup!
Yeah Technology Connections explained it very well, and demoed how it vaguely works but his mechanical TV didn't really show anything clearly like this one.
Same, amazing Chanel!!
i was so suprised when the sound came on and it was Danish
One of three best channels. Alec goes from nice kid to grouchy young man in a few years. 😊
Mechanical televisions fascinate me, mostly because they are proof that there's always an alternative way of doing things. And I think that's the core principal of science, not get stuck in a rut of doing the same proven methodology over and over again, but to explore different possibilities and to record them for posterity.
Because who knows if there's something in the design of mechanical TVs that could hold the key for a future technology we try to develop.
Imagine only having radio, then this comes along. It must've seemed like magic!
Glad some of you think this is amazing because it really is. He put a lot of work into this presentation. MechTV is VERY difficult to reproduce.
This truly is amazing. Those inventors and engineers were ahead of their time, glad some people still appreciate it
I watched it on my LCD monitor and for a second... I think of how was I watching everyday youtube video for granted.
Frankly AMAZING for 32 lines!
Thank you. This is an old video by now and the results are actually even better now. This is mainly due to very precise Nipkow discs made with a laser cutter.

I had never heard of this until about two weeks ago. Then I set out to learn more about it. Now here's a video actually demonstrating a working model. This must have been amazing the first time it was seen.
You've got to love the people who find the time to take the time to reclaim this sort of history. And who take the time to make a video for us here on RUclips.
Alric Knebel and now you can buy some led wheel and watch films. Find it on ebay
@@semyonchernykh4694 More significantly they could(& did) transmit it wirelessly, though it didn't have much impact as electronic TVs took over very early(in the 1930s).
Just to clarify, projectors used film rather than tape. The first film type used had an unfortunate attribute of being very flammable(nitrate), which wasn't ideal next to a very hot light bulb, in a building full of people !
That face could give me nightmares...
+Fudgerocket Not for me, the face that gives me nightmares is the Klasky-Csupo Robot logo which gives me a heart attack
I remember that. I also remember the bird logo at the end of Hey Arnold.
Fudgerocket Snee-Osh - that's annoying logo (like Klasky-Csupo Robot which is cheesy, scary and annoying)
An Endless Funny Nightmare For Me
Thease faces are nightmares cut the audio play them reversed see what they say then.
This is amazing! I had never heard of mechanical televisions until today. It's a little eerie, but so instigating. It must have been so mind-blowing in the '20s. The '20s!
My understanding of TV has grown exponentially since I now understand mechanical TV, Wow how very freakin simple it was!
John Logie Baird would have been pleased his pioneering work lives on with enthusiasts such as yourself, Sir!!
During the 2nd World War years John Logie Baird went on to develop a 1,000 line High Definition colour TV system which he called "Telechrome" and he also demonstrated 3D colour TV. It's said much of his work was destroyed by a German bombing raid and he died in 1946, and his Telechrome system was forgotten about due to Britain's infrastructure having been destroyed by five years of war.
+Martin S
Baird lost most of his development during the war but his HD CRT television was impractical, it was huge and I mean fucking huge it weighted half a ton, it produced astonishing imagery from the accounts of those who seen it but the television cost more to buy than any rich man at the time could afford, the Soviets subsequentaly is the second one to produce greater than 1000+ lines television black and white for conference use, it was never put into production which is a shame because it would been cool if they did, it was much more economical practical television.
@@ThatsnewsTVI read about John Logie Baird 50 years ago when I was a child. I am happy to know his story was not forgotten. Might be, Baird's electromechanical Tv , be unexpectdly useful in some field in future.
When Baird first showed off his invention, the audience gasped and asked "Is there notthing else on?"

@Allen S We do use it today, it's called; Television.
You could say the same regarding EVERY invention throughout history.
@Allen S this was one of the first TVs ever made. It ended up basically being an impossibility sadly, so they found out CRT and started making TVs with that and all the way up til about the 2000's plasma tv was more in use, then LCD became more mainstream. Then LED came, that was basically LCD but with a different backlight system. Now in the modern days, we have variations of LED tv and OLED. OLED which is no longer LCD, uses thousands if not millions of tiny RGB LED lights. Its called evolution of technology.
@Allen S you are an idiot who doesn't how how technological invention happens.
People in the 20s: best video quality ever!
People now: I cannot see anything!
Feels somewhat steampunk-ish... I like it.
It could be out of a movie like Brazil.
Reminds me of Bioshock Infinite
That could make sense. If the "steampunk era" was a industrial revolution it could be from the early 1900s and which it was. It would be quite cool if the steampunk era existed though.
The Apple Macintosh 1984 commercial.
fascinating technology.
I feel like there is something hidden something great to this invention where another great idea or invention could be adapted from this I'm amazed at this truly
That's actually astounding that you got it done and working so well. Mad props
Fred Flintstone TV! LOL and awesome! Cool vintage...
I'd love to play gta5 on this.
Theoretically possible
Edit: youbjust need an algorithm to light up the diode in correct timings, and boom. Gta
I am not sure GTA comes in that high of resolution....

The Televisor and PAL625-converter seen here took me about 1 year. It was build i 1999/2000.
that is both the most creepy, and coolest thing ive seen in awhile
clear enough for watching porn

Yep

Well The Paramount Astoria Girls danced in very little clothes on the Baird Television System in 1933 - and the live transmission was recorded privatly.

I don't know why they put so much effort into developing a TV. Watching small moving pictures on a screen will never catch on. lol Luckily it wasn't the mechanical TV that caught on. Great job getting it to work & illustrating it for us. That really is pretty cool.
I do say sir this is a grand invention!
It’ll never catch on!
I love old stuff like this. Awesome! Thank you for sharing!
I am 41 damn years old and just learned about these today from the Technology Connections video. It has such a unique look from the thick vertical scan lines, almost like the Princess Leia hologram or the spinning LED persistence of vision displays (which are remarkably similar!). Very cool!
A very simple idea, but still amazing to see in action.
This is what started the birth of television. Without this, it would been just radio broadcasting our whole lives, and TV would of not been invented. I hope I am find my own way to build my own mechancial television in the most modern way using Arduino and Raspberry Pi. This type of TV used AM broadcasts for the audio and Shortwave radio for the video signal.
The definition is breathtaking. Could never ask for more.
this is simply beautiful!! congrats
I am in awe. Never saw smth like this before - and it is f***ing GENIUS !!!
Whoooaaah, this is very impressive,considering the technology works totally different and thus requires a different signal, so the way how a convertor box could convert that crt signal into a mechanical signal is incredible ,now if we only add a color wheel on top of it,that would make the picture complete.
I still can't believe the great great great grand father of our modern oled tv is alive somewhere in the world... respect
I love this experiment because this is the way television was invented.
BEAUTIFUL and amazing!
This was also CBS's first attempt at color TV. It used a large rotating color wheel and, while it produced fairly decent color, if you wanted a 20" screen, the rotating color wheel needed to be at least 45" in diameter. That would make for a large cabinet. The FCC turned it down when it was revealed it was not compatible with black and white broadcasting. So you would need 2 TV's. One for receiving black and white and one for receiving color. This is why CBS was the last network to adapt to the electronic color system developed by RCA. They were mad that their color system wasn't adopted.
What??? What does CBS' electronic colour television system have to do with Baird's all-mechanical system? Zilch. The mechanical system never gained widespread use, and by the time anyone was looking for a colour system, they weren't using fucking wheels, troll.
The two systems have absolutely nothing in common apart from requiring a spinning wheel. You have no idea what you're talking about.
wow, such a big brain
The CBS color format was superior to the RCA but there were already hundreds of televisions and stations broadcasting B&W programs at 30 fps. 30 fps was chosen as AC electric power in the U.S. is at 60 hz. The RCA format, now known as NTSC, was established at 29.97 fps to allow the bandwidth to facilitate the color burst signal but the change in frame rate threw the timing of the broadcast off so a compensation methodology was devised known as drop frame. Television broadcasts now are all recorded in drop frame mode (look it up). Now I'm really going to bake your noodle. If you recorded a 30 minute video on your consumer video camera and timed it to exactly 30 minutes and took it to your local tv station and asked them to air it, and they did, your video would run into the next program's time. Your consumer video camera is probably recording at 29.97 fps but in non drop frame mode.
The CBS color TV system still used a monochrome cathode ray tube to generate the image. The color wheel was just a way to cycle quickly through red green and blue repeatedly relying on the human visual system to fuse the rapidly changing separate color images into a full color image. Unlike the mechanical TV in this video, the wheel had nothing to do with scanning the image. And the FCC knew all along that it was incompatible with existing B&W TV, it wasn’t a surprise reveal at the last minute.
in the event of an apocalypse thiss would be the easiest way to bring back television
I've seen one of these before in a museum. Great to see one again! Thanks for playing it for us! -- Atco
This is beyond cool! Thanks for uploading it!
awesome stuff, love the choice of content to play on it to!
Way better than high definition.
Well it was the way to high definition. This is equal to the 30-line Baird television System in 1926. Baird went on to develop all-electronic televison. In 1944 his telecrome tube in test transmissions showed 3-dimensional color pictures of 1800 lines.
I was being sarcastic of course and yes at the time it was the best they could do back in the mid 1920's. That is an amazing video you posted and I thank you for it.
My goodness it's good to know tv technology has really improved over the years .if we still had that technology of yesterday .we really would be missing out on so much.
Actually it is amazing that Baird invented the sync pulse. As he moved from a fixed axis so that sender and receiver disks ran exactly in parallel, the sync pulse allowed to regulate the receiver disk to be in sync!
I loved this
I congratulate you for the work!
If someone told me in my youth I could watch and hear people who aren't in the same room, I wouldn't have believed them! Progress is amazing!
Ummmm how old are you??
@@fcubeboy4959 left on read😬

Only one channel at the start and still more stuff on tv than their is now.
Love this awesome invention
I may be a person who loves steam engines and the history of them, but it's nice to see the other inventions that made us what we are today. Thanks for sharing this video about early television. I'm not much of an electronics guru, but I think this is way cool.
Trippy! Thanks for posting.
Very cool. I saw one of these in a museum and really wondered what it looked like running.
This is wonderful, a fantastic achievement. I love mechanical TV.
Very cool- I've always wondered what scanning disk TV looked like. Thank you!
It is really beautiful.
This deserves more views.
Cool stuff. Amazing really.
As Google have marked John Logie Baird's first broadcast 90 years ago today Jan 26th 2016 the bulk of our good TVs are still mass produced mainly in China,and although my own Flat-Screen is a joy to now linking my Samsung smartphone to my Samsung TV ....wow...My how thing's have changed on the Tech-Front ...Cheers great video i found in the Independant today
*Wow, that's some 4k right there*
incredible. thanks.
Amazing, amazing and amazing.
Ahhhhhhhhh I remember the good ol days I was a kid in the 1930s and my dad used to have this tv on.
Dear Lord! You built one of these things? That's crazy! and awesome...
That is fascinating. Thanks for the vid!
so good
Incredible
This was uploaded one day before I was born.
So when you were born, this television system had not been used for almost 75 years. 2025 is the 100th anniversary of the first true television picture.
@@televisionbb basically yeah.
Nice! Thank you.
@AngryVGFur The small white disc is for syncronisation. It rotates on the same motor shaft as the Nipkow disc and has 32 slots - the number of lines in the picture. A LED/photodiode arrangement makes 32 impulses/picture of this. An IC4046 compares these pulses to the syncronisation pulses of the video signal and automatically adjusts the motor speed.
For almost 100 years still working Flawless and the sound effects are like Modern TV
That was incredible!
Fascinating
Still looks better than RUclips in 144p...
Fascinante
Wow!
Zoltan, do you remember Hungarian Tungsram? We had very fine TV Orion Tisza AT 403.
You are quite right about the dark bars. They are only due to different scan rates. I use the slow shutter effect to give a more realistic impression of the picture. Viewed directly you will see no bars but the whole image flickers with the 12 1/2 Hz picture frequency. I own a copy of the Abramson book myself. It is quite a remarkable collection of television patents and is (without total succes) perhaps the first book on the history of televison trying to be impartial.
Thank you for your interest :O)
That is amazing!
you did a very good job ,, the best i seen
This is awesome, couldn't imagine people realistically using this in 30s though
1 second ago
But they used it realistically. At one time in history this was television. The same TV machine with laser cut scanner can be seen here: ruclips.net/video/9JkmXnUyhqw/видео.html
AMAZING! Not only have you built a mechanical television, but a signal converter that accepts DVD video?
Simply amazing.
Oencodjxehoegxjwbcijdjw
It is wonderful.
This is pretty interesting.
I can feel it..coming in the air tonight
Wow, that is the coolest thing.
The converter is a counter picking out every 4. line in every 4. picture (=12 1/2 hz picture frequency). These lines are divided into 96 'points' and the middle 32 of these are for 64 lines (4, 8, 12,...256) stored in a RAM - this giving a picture in the RAM of 32x64 points. 2 RAM circuits (32x64=2048K) are alternating between writing from the PAL signal to one RAM at 96x15625Hz=1.5MHz and reading from the other RAM at 32x70x12 1/2 Hz =28000Hz. 6 points (70-64) are used for syncronisation.
@@msroper5287 you are aware of the fact that Baird went on to produce 600 line electronic projection television with mechanical color weel (later use on the moon) and the worlds first fully electronic color television system running at 1800 lines in test transmissions?
Another step for hypnotised people . They conquered space , the inner space , the mind . The best idea since the wheel .
If John Logie Baird was alive today and he saw a 65" flat screen t.v., he probably would have cried out 'look what they've done to my t.v mom'.
This is better than what I have at home now , I gotta get me one
Thank you for your interest. The converter accepts any PAL 625 video signal.
The PAL-N system, like we use here, in Argentina...thanks a lot for show this wonderful video of this masterpiece that started the TV era!
Do you know who is the singer?
Greetings from Argentina!
@@ALEFILES The singer is danish actor Axel Lading Larsen know as Buster Larsen (september 1, 1920 - december 18, 1993)
Hey, my favorite show is on.
makes you wonder about dvd and cd drives, its just a braid disc with millions of pits just like this 100 yrs old device lol. its really neat! the computer disc was really invented 100 yrs ago! lol
@BARONSCHWARZWALD No, there is no cathode ray tube here. The scanning is done mechanical with a Nipkow disc. The picture signal modulates a cluster of white ultra high bright diodes. In the old days this was done with a neon tube.
Nice
Wow that is cool, a television image using only one light sensor.
It has a decidedly-humorous, Heath Robinson aspect to it.
Cool!
cool that beauty
wow nice
