Early TV, December 1928

Don't let my history of television professor see this. The books tend to stick with Philo Farnsworth. I guess Philo will just have to take credit for the fusor. A 1 1/2" TV that has 10% of the vertical resolution of SD is very impressive for 1928.
 
Wow! Just reading that makes me realize what a miracle it is that we have any technology at all. I mean I can understand the wheel, but I would have stopped after the cheeseburger, you know? To be able to come up with something even as simple as that TV in 1928 just boggles the mind.

Long before the "All Electronic" guys like Farnsworth got off the ground, the Mechanical guys, like Baird had a head start with the mechanical system. The truth is that one one person invented TV, many had a part in it, with each adding to the technology required.

Baird does hold the record for the first recorded TV image. He took the audio output of the device and recorded it to a 78 RPM record. The idea was to let people hear what a TV image sounded like. MANY years later, someone took this recording and converted it back to a moving image.

The disk shown in the article was called a Nipkow disk, and it allowed for scanning the image with a single disk. (A Very Clever idea.)

Part of me wants to build the mechanical TV system using modern day technology for shortcuts. With improved technology, I'll bet I could improve on the low light performance. :happy:
