Baird Test Card Drum

Postby McGee2021 » Fri Sep 09, 2016 2:43 pm

i am building a relatively simple replica of the Baird test card drum, or whatever you want to call it, like the carousel or rack. I was assembling my old Baird test-cards i printed off, and i was going to have a local artist draw some new, custom ones, since where i live is a major tourist destination during the fall (when i cant go to town for "reasons unknown"), and it has been considered an artist colony for the past two centuries. But anyway, to get to the point, i lost the newsletter that had the example of scattered lettering for transmitting a name on Baird's Televisor. :oops: I think one of the examples was for a lad by the name of Freddie Carpenter. So if anybody could give me a scan, it would be much appreciated, so i can finish this project before i get replacements for my lost newsletters. :D
John Logie Baird was obviously the man who sowed the seeds but did not reap the harvest.

The electromagnetic spectrum has no theoretical limit at either end. If all the mass/energy in the Universe is considered a 'limit', then that would be the only real theoretical limit to the maximum frequency attainable.

Most of them are from the man with a flower in his mouth, you can read about it here:http://www.tvdawn.com/earliest-tv/the-man-with-the-flower-in-his-mouth/ on Don McLean's website.

Found the test-cards, It just took me a bit of exploring on the forum. They are about half way down the page, Here: http://www.taswegian.com/NBTV/forum/viewtopic.php?f=1&t=526

Time to try out scattered lettered writing!

I have ordered a few web cameras, and i still have to make a selector switch to switch between cameras, such as the one for the 'studio' and the testcard drum.

Thanks, as soon as I get ink for my printer, I'll start to print them off and assemble them.
