That must have been a lot of fun. I would have enjoyed doing that
myself. Ira.

Looking through the Television Journal of November 1934, I came across this
advertisement.
'May be used in place of any existing Neon Lamp without alteration' caught my
eye. I guess that is in the context of a 1934 telly.

No, never. Is it this thing, or is this mercury vapour?

I remember my dad telling me about those original old
TV sets from the mid 1920s. He described the rotating disks
and he did see a display version of it somewhere in Chicago
when he was a young boy. When he saw it, he said it had
a picture of Felix the cat which was on a rotating turntable
I'd scan bits of the books and post, but there is probably more on the web
anyway. The 30 vert lines pic was 'awful'. And yes, most had lenses.
If anyone wants me to scan that pic, shout.

It was easy, but became slightly more complicated when the 'video' from
the P.E. cell was transmitted via 'radio' to a receiver at a remote
point. At that time the two rotating discs were no longer on the 'same
mechanical rotating shaft' but still had be held in sync with each
other, therefore
There is a lovely pair of volumes of Television Today [1930s, after acorn
valves] , Newnes, (probably weekly and then bound).
I absorbed Dad's copies when I was a kid and started a disk Tx and Rx at
school. Still have the pieces - waiting for the 'round tuit' I need to complete
it.

In the late 70s as a ten year old, I spent a while drilling a spiral of holes
into a12 vinyl album. I have no idea where the plans came from but the idea
was to have one side the camera and the other side the output ie at 180
degrees. Did the drilling, got the meccano motor drive working got
10 matches
