Sunday Evening Brain Dump


Good evening Lovelies, and welcome to our first Sunday Evening Brain Dump! Tonight’s edition is brought to you by Abigale Miller, aka Tactical Bikini Girl. This is our chance to end the current week and prepare for the one ahead by clearing the mental cache of things that we’ve found on the Internet and in the world at large. Without further ado…

Mechanical Television

Before television was an entertainment medium like radio, it was conceived as a form of communication akin to the telephone. Early televisions had screens about the size of a cigarette pack, and users had to be in a dark room or under a hood to see what was happening.

How it worked:

Mechanical TV uses rotating disks at the transmitter and the receiver. These disks have holes in them, spaced around the disk, with each hole slightly lower than the other.

The camera is located in a totally dark room. A very bright light is placed behind the disk. The disk is turned by a motor, so that it makes one revolution every frame of the TV picture. In the Baird standard, for instance, the disk has 30 holes and is rotated 12.5 times per second. A lens in front of the disk focuses the light on the subject being televised.
As the light hits the subject, it reflects into a photoelectric cell, which converts the light energy to electrical impulses. Dark areas of the subject reflect very little light, and only a small amount of electrical energy is produced, while bright areas of the subject reflect more light, and therefore more electrical energy is produced.

In 1928 Charles Jenkins was given the first broadcasting license, and by 1935 there were 25 television stations in the United States broadcasting Vaudeville and other entertainment.

Nixie Clocks


If you’ve been building stuff in Fallout 4 and can’t figure out what to do with the Nixie tube, the bad news is you can’t do much. The good news is that Nixie tubes are widely available for purchase in the former Soviet Union, and they can be used for nifty DIY projects.

More on the lovely Nixie tube:

Back in the 1970’s, the now largely forgotten, nixie tubes were the height of display technology. Resembling vacuum tubes, nixie tubes are actually a cold-cathode tube variant of a neon lamp. While still functional they are fragile when compared to LED’s and to some extent LCD’s. Having formerly graced the cockpits of aircraft, the faces of countless scientific tools and other interesting uses, they are now more commonly found in expensive art clocks. 

If this is up your alley, go and grab some before all the weirdos snatch them up. They’re still at the point of being obsolete without being retro cool, so prices are reasonable.

Favorite Weekly Podcast

Nightmare on Film Street has been keeping us company at work this week. Kimberley and Jonathan are two horror fans with a weekly podcast wherein they discuss various horror films across the decades. This week’s broadcast was a comparative analysis of two David Cronenberg movies, The Fly and Videodrome. I personally prefer Videodrome, but their discussion of The Fly was both humorous and insightful.

Have a great week everyone! Stay creative and don’t work too hard.
