DIY Scanning Disk TV

[yagosaga]

My scanning disk monitor has got a new housing.
The woodworks were done by a friend, Ulrich Barkow, who is a retired physicist and the master of the city of Broitzem here. When he saw the first draft of my monitor working, he was so impressed that he asked me to make a new housing for it. He has a special workbench and tools for woodworking and will introduce me to do the same. I am fascinated and I wish I can do it in the same way. See the photos:

He has put the motor and the disk bearing into a wooden block, which is fixed with screws at the ground plate. The wooden ground plate now is removable. The surface of the wood is oiled.
I have constructed this set in this way that everybody can see it working from the outside and understand how it works. This is the "philosophy" behind this set. I want to use this set for teaching childs and young people to understand the fundamental principles of television. When they carefully observe this set they found the fundamental principles by themselfes and can explain it. This is not possible with modern tv sets.

You know, I just thought of some crazy idea yesterday.

Use an array of UV LEDs for the light source, but on the disk, instead of holes for scanning, use a UV pen, and and mark where the holes supposed to be, so in the dark, its got a cool looking effect.

Then I have to look on the back side of the disk. But why not using UV LEDs with holes in the disk and put a phosphored screen before the disk?

because I dont want to look through holes, and I want maximum brightness.

Yagosaga, that is very nice looking, and I also like having the works visible so people can see what's in it.

hehehe, I just got an idea, that might improve picture definition and brightness.

I got an old fiber optic toy lying around, I might just cut a strand, and cut that strand into 32 small peices, and they are VERY small fine optic wire.

And glue them into each sync hole, and that optic cable passes all light, and its small enough to achieve picture definition.

Im going to try this.

Too much difficult. Why not using a mirror screw like this:

[mbates14]

how would it be difficult?

[mbates14]

that would be kinda hard to build.

Screw units require los of $$ for all the machining and other. If someone was to pony up dough, should set up to watch maybe TV programs since so expensive. Has an anyone built a LARGE unit as seen in some 1930's photos form Europe?? These can be made for higher reslution. Shame not to many made, I guess since so complex on optics alone and probaly were expensive=luxury items.
