Here's mock up of the Tellyniptrix. The small 5 inch dia. Nipkow disk has not yet been drilled and nothing is yet bolted down.
But one should be able to view either B/W 625 TV or DVD or a live 625 camera input on the end of that portable probe.
Then see the NBTV converted picture on the Niptrix, mounted on the wall above.
Frames per second of NBTV camera and synced Niptrix to be adjustable from one to 100 plus .....just for viewing experiments.
