For those following this, here is an update..........
Here are 2 photos of THE NIPKOW NIPPER.
As I cannot do any trials re Dome light sensor/illuminants until I have the means to rotate the 2" dia film at 750 RPM I have stormed ahead with the mechanics as you see.
You can see a piece of loose film where the 2 perspex washers will hold the final film image. On the right is the adjusting part to move the film bewteen the perspex washers to get scan hole alignment under high magnification.
The mini video camara is the black thingy with a black wire coming out.
The white tube in front of it is the extension tube for the camera's lens.
You will see that the camera is on opposite side to where the NBTV picture is normally viewed. I intend to have normal viewing on the right hand side....for those with good eyesight !
On the left the inverted image will be seen by an inverted camera.
The .004 inch dia holes show up well on the first 120 film I shot BUT although I took 12 photos of disk with various exposure/apertures to get the best, the focus is slightly out so I am going to retake at various focus sittings.
The old Ensign Selfix has no means of accurate focus at close ups so I am
focusing on a home made frosted glass screen where the 120 film runs.
Camera lens is only f4 so I had to blast lighting onto the trial tapering focusing steps........45 degree upward slope with lines every 1/4 inch
to see plus/minus distances for focusing.
More updates, probaly after Xmas now...........have a happy one, BTW.
