32 Line Mechanical Television III

[joeylawn36111]

Man, those old commercial jingles were awful.

[kovona]

I thought 48 lines was the standard during the 1920s television "excitement"?

[EnerG15]

I've built a mechanical television and I was wondering if you could tell me how to convert ordinary video signal to 32 line signal?

[modderpomp]

how the hell does it work?

[Omarti1]

thats how rasterization works good to know

[franchute63]

you're really doing a good work. and I want to add my congratulations to the others comments.

My regards, Roger

[miguelmouta]

Good work . Congratulations. Thank You for posting.

[creaturebotman]

Very great work!

Every since I was a kid i wanted to make the Nipkow scanning disk. You inspire me to just do it.

My hats off to you sir!

[AFNYOAQIS]

not quite color tv

[windoes98se]

catchy gingel

[AFNYOAQIS]

the black bars are from the camera...

you dont see them in real life.

[instante101]

Utterly amazing.

[GreenVI]

Did the Nipkow Disk use selenium?

[laurdy]

yes

[mubd1234]

The guy who owns this mechanical set really needs a color tv!

[TeslaMaster]

Yes, I will create a mechanical color set, and then you can watch this ad in color on the Nipkow disk. ;-)

[Kargaroc286]

@Kargaroc286 now, the color version of this is up

[rasticlock]

Its not fake,

1) you can notice that the frame is repeated vertically.

2) The high definition picture is because there are an horizontal limit of 32 "pixels" (lines),

but vertically the resolution is NOT limited by the mechanical disk (i mean is virtually infinite)

3) If you look at the video response you will notice the process from the start, when the image slowly starts to get sync.

Good Job Teslamaster !!!

[Kargaroc286]

actually the vertical resolution is limited to 70 pixels (or lines)

[kargaroc386]

analog video has no pixels, as it is continous, just split up into scanlines

[windoes98se]

grate point!

[NipkowDisk]

Way cool. Thank you for posting this!

[TeslaMaster]

In the next year, I will try to make a better video for Youtube without the large vertical bars resulting from the different frame rate of camera and Nipkow disk. But for now the mechanical Nipkow disk tv set is on an exhibition of the World Heritage Voelklingen Ironworks. I have to wait until I get it back.

[t0nito]

Maybe you'll get less bars if you can get your hands on a PAL video camera as it records at 25fps which is exactly double the fps of the nipkow disk. I'm sure those bars would be very much reduced.

[Kargaroc286]

it's not fake. look at the guy's head as it's looking at you. it's really blocky

[dalekmoore2004]

That proves nothing it would have to be a 100

hole disk to give that quality, the tv camera picking up the image shows its a fake ...even the phosphorescence of the tv behind the disk shows up .

[TeslaMaster]

No fake! You can find a detailed documentation about this 32 line tv monitor by searching on Google and using the words "Hybrid Mechanical Television Receiver". Then you will find my web page about technical details.

But it makes me smiling when I see that people keep it as a fake.

[dalekmoore2004]

This is a fake !

how it was done you have a tv behind the nipkow disk ! i have made baird tv's ,having a cathode ray tube behind a baird televisor is an insult to john logie baird !

[albertusj]

The multiple images stacked on top of one another is typical of a real nipkow disk display system. A CRT behind the disk would have produced only ONE image, not three.

[mubd]

It would be quite obvious that a person watching this would want color tv....

[webmasterec]

TeslaMaster - really nice work there!

For those of you interested in the mechanical TV stuff, there's a whole group (based in the UK) dedicated to this stuff.

Look up "Narrow Bandwith Television Associaton"

[fromthesidelines]

When RCA produced a 1956 promotional film, "The Story Of Telvision", which purported to be a history of the development of the medium {through David Sarnoff's corporate revisionist history}, Paul Nipkow's name was NEVER mentioned. Vladimir Zworkin, who appeared in the film with Sarnoff, was credited as THE man who perfected TV as we know it....

[TeslaMaster]

This is from my camera, since the frame rate of the camera is appr. 30 frames per second, and the frame rate of the Nipkow disk is 12.5 frames per second.

[Kargaroc286]

so the vertical black lines that go from left to right would not be there if this wasn't from a camera?

[TeslaMaster]

Yes, this vertical black bar depends on the camera's frame rate which is not in sync with the Nipkow disk.

[TeslaMaster]

A kit is available at MUTR. Search with Google for mutr and televisor. Replace the red LED in the kit with white LEDs. My own televisor is on an exhibition of the world heritage Volklinger hutte until May 2008. When it returns I can make new videos.

[RABBIDGamfan]

Wow. This should be sold as a hobbyist kit or something. Do you think you could put a downloadable 60FPS version of this somewhere so we could get a better look?

[TeslaMaster]

I will try it. But then with a function which eliminates the black bars in the picture. Mechanical tv looks much better in real life than in these videos.

[frugola92]

very nice when another video mechanical tv?

[ufoengines]

Yea, I remember watching that ad on my family's black and white table top GE portable set in the 1960's.

So here I am watching a black and white tv ad reproduced via mechanical selling me a color tv

all shown to me on the internet.

Cosmic!

Anybody know where to buy a Mechanical TV kit?

[TeslaMaster]

Your story is fine! Thank you.

> Anybody know where to buy a Mechanical TV kit?

Try it with Google and search for the words "mutr" and "televisor". Mutr is offering a mechanical tv kit which is easy to assemble.

[jorgedamian]

muy bueno

[goqwertygo]

WOW
