Video tape for tv's ?

Postby End2end » Fri Sep 01, 2017 6:06 pm

I've just had a crazy idea but want to ask advice before going ahead and damaging something.
The idea is to take a vhs tape apart and use a single cell with an led (perhaps flickering) behind it to light it up giving an image on a tv in a building.
Would this work?
I've never seen inside a vhs tape before enough to look at each cell.
Thanks

There's nothing to see on video tape, just magnetic ferrous oxide. A blue/white led with a flicker would give the appearance of a TV in a darkened room. A real working large screen for the station forecourt seems a possibility,link

Ahh I thought they were like photo film except in colour rather than negative.
Thanks for the link too altough a little pricey for my idea.
A peice of coloured film would probably do.
Thanks

I saw a layout that had a small working TV in a shop window. One of the operatives told me it was the view finder from a cannibalised video camera just playing back a saved file.

How small were the images on those toy view finders?

Alternatively, you might have hit on something for a large cinema screen using a single frame from a 35mm cell. I'm logging that one for possible future use. :wink:

I think the doll's house one said it was a 1.8" screen, in 00 you would be looking at the sort of display they have at pop concerts and sports events. Small LCD screens are relatively easy to come by, it's the electronics to drive them that aren't so readily available.

Hmm now there's an idea! I keep seeing these at boot sales recently.
Thanks

Why not canabilise one of those key-ring photo-viewers. You could put any pictures you like on it and have it continuously scrolling through. They usually have a 1.8 inch screen.

I think for my intial idea of a tv that would probably be too big.
Good for other larger screens though. :)

Bare in mind that the old roundy cornered B&W TV's of the 60's were barely over a foot wide, so that's just 4mm! Even 22" colour TV's would only be 6mm wide! The only realistic size would be in a TV shops window, were they would display the latest huge TV (probably only 29"). I have seen the video camera B&W viewfinder (12mm) used and the back of an old digital camera (24mm) to good effect at shows. An idea I am contemplating is to use an old phone, either as the actual window of a TV shop or horizontal with a mirror to reflect the image into the window. The point being, you could record not only several TV's working in amongst static items, but also customers milling about! (I have an old Iphone 3 stowed away for future prototyping). The other option is to use a larger screen and use lenses to reduce to a smaller screen as a back projector, probably mounted below the layout and reflected through a 45 degree mirror. The easiest option for a house is to use red, blue and yellow flickering LED's to give the effect of a TV light behind the net curtains.

You could always stand an empty TV cabinet on top of the screen. Just use a small mirror in the cabinet angled at 45 degrees.

I received an email from Gaugemaster this week showing a new disco light. I completely overlooked it as a possibility as I won't be building a disco/party scene. This may be possible rather than the elaboracy of an actual screen. http://www.gaugemaster.com/item_details.asp?code=TTSL10
I also found this from Faller but I'm not sure what it is exactly. http://www.gaugemaster.com/item_details ... e=FA180710

And finally diverting from the original post I also found this.... http://www.gaugemaster.com/item_details ... de=MN43868
A disco coach! :lol:
Not for me but a unique and funny idea. :mrgreen:
Thanks
