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.

May I recommend a CRT then? ;)

lol.

Naa, I wondered what effect that would look like if I used a UV marker for the scan holes. I wonder.....

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:

how would it be difficult?

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.
