My Christmas present to myself - MUTR mechanical televisor
At last, a mechanical televisor is available to the public again. I've just ordered one for myself.

Re: My Christmas present to myself
Hi Steve,
Thanks for pointing this out, I might just have to ask Santa for one as well as the Enigma-E kit already on the list... Cheers, Kat |

Re: My Christmas present to myself
If it complies with the original Baird standard or the 32 line SSTV standard then Darryl's first converter will work. That's the more expensive multistandard design, not the popular £150 unit.

Re: My Christmas present to myself
I don't blame you Paul, it's well worth having. What do the metric sizes quoted convert to in English, that is, Inches?
Thanks for that Jeffrey, I have been musing with feeding the audio from The Dawn Of Television CD ROM 30-line recordings to it, presumably these may give a fair picture if it is 30-lines? If so it may well be worth talking to Darryl about a converter for it, as I rather like the idea of watching 30-line Television over-the-air as it were, and then you're equipped of course should an original Baird Televisor come along. Great stuff! |

Re: My Christmas present to myself
Hi,
I found a movie of this in action on "YouTube". "The image is tricky to view as you have to sit dead square onto the tiny image and it's ever harder to film. The light diffusor works ok on the naked eye but the LED appear to shine straight through and into the camera lens causing an annoying hot spot on the movie. Also the annoying vertical black bar you see scanning over the image is an artefact generated by the lack of synchronisation between the televisor and my digi-cam. You don't see that in real life."Cheers, Kat |

http://www.nbtv.wyenet.co.uk/hot.htm this appears to be a 30-line (not 32-line) system. Quote:
I should also be able to plug one of the colour channels from my 30-line mechanical camera into it for live pictures - and also view the kit CD at higher quality (in one colour) on my monitor. Quote:
See also http://www.nbtv.org/kit.htm for useful detailed photos of this new kit. Steve |

Unfortunately there was very little interest in this project, so it never went anywhere. Darryl |

Re: My Christmas present to myself - mechanical televisor

It is a 32 line unit. Jim. |

Re: My Christmas present to myself - mechanical televisor
Thanks for the info Jim, glad to know you have got yours successfully.
It's a shame that it's 32 line, as this will not all.ow the playback of the Baird recordings, but hopefully Darryl may be able to come up with a converter? If so I'll definitely be ordering one. Peter. |

Re: My Christmas present to myself - mechanical televisor
Darryl's multistandard converter will certainly do 32 line output.
As for converting 30 line sources to 32 line, I suspect that's a software job running on a PC. |

Re: My Christmas present to myself - mechanical televisor
If you want 30-lines, why not simply make a 30-line disc yourself and fit that instead?

Re: My Christmas present to myself - mechanical televisor
Just finished building mine, worked first go, and includes a built in test card (what I thought was an 8 pin op-amp was a serial microcontroller!).

Re: My Christmas present to myself - mechanical televisor
For those which are interested: I have posted three videos on Youtube, showing the video performance of a 32 line Nipkow disk monitor:
http://www.youtube.com/watch?v=9DFcYRxFdTI http://www.youtube.com/watch?v=2dmY43KeBuE http://www.youtube.com/watch?v=osF5gg6RKL4 But as one can notice I haven't found a solution for the problem of vertical interference bars, resulting from different frame rates (digital camera vs. Nipkow disk). Kind regards, Eckhard |

Re: My Christmas present to myself - mechanical televisor
A quick question to anyone who is using one of these kits... Is it a white or coloured led?
Thanks guys Andi

Re: My Christmas present to myself - mechanical televisor
Hmmm... I am guessing they used that to make it feel more original. I wonder how it would look with a white LED?

Re: My Christmas present to myself - mechanical televisor
Don't know if this will help you guys, but there's a little program at the bottom of this page that claims to convert any video file (that Windows Media Player can play) into 32 line colour narrow band (black and white compatible)
http://users.tpg.com.au/users/gmillard/nbtv.htm There's a viewer too! David |

The older black and white version has a larger sync bar which improves synchronisation. The newer version with the colour option has a smaller sync bar to give more space to video content. This needs a much longer time to get the scanning disk into synchronisation. Please PM me if somebody need the older b/w version. Eckhard. |
