Some of the photos obtained are amazing although exposure times are long. The pin hole cameras are even made out of paint tins
A one gallon camera
I wonder if anyone has ever heard of a NBTV camera using a pin hole lens?
Probably the light obtained would be insufficient for any kind of photosensor behind the Nipkow.
It needs a very, very, very slow rotating Nipkow to get a long time exposure, record it, and then play it back at normal 12.5 revs per sec speed....
Just a thought.

This goes back to previous threads...if only we could obtain all the back numbers of the NBTVA News letter. I for one, would be prepared to pay for copies to cover printing etc.
When I was a member of the Eddystone Radio group one could obtain all previous issues.
But I suppose it's all a question of time and everyone does it all on a voluntary basis.
Maybe a small print over run each time to keep a few back for newcomers to buy in the future?
