This makes me think about the people who built calculators and computers in Minecraft using the in-game “electricity” system called Redstone. It started as just making switches that could automatically open doors when you hit a button or stepped on a pressure plate to trigger it, but it eventually grew into more and more complicated electric systems until people eventually built calculators and even computers in the game. I remember seeing a video where someone built a computer in Minecraft that was running Minecraft itself in a scaled down version, on a screen made of Minecraft blocks. Someone even built a computer that was able to connect to the internet and they were able to order a pizza through the game that then was delivered to their house. I’m sure by now people have built huge and even more complex computing systems in the game and I have no idea what their capabilities even are at this point.

The Z3 was built with 2,600 relays, implementing a 22-bit word length that operated at a clock frequency of about 5-10 Hz.

If you could repair a TV you could work for a big name company going to hospitals installing, repairing and maintaining high end medical x-ray. You were a hero and even the Doctors worshiped you. We were networking image transfers before they knew what to call it. We could do 3D imaging using analog video. You got the image in a day or two because computers were too slow. CT, computed tomography was invented by an engineer that worked at the EMI recording studios. Then the companies handed out laptops and said figure it out. Dial up. The blood ran despite how hard we tried to reprogram those folks. Now the software and every other kind of repair are two disciplines. Benjamin Franklin was your last renascence man that could know enough of everything to function in any subject. Its only going to get worse. How long before you ask your computer "Whats wrong?' A you have to decide if you can trust it. I'm hanging on by my finger nails.

I'm disappointed that you made no mention of Colossus. It may not have been a programmable computer, but it was an electronic logic machine that used thousands of vacuum tubes to statistically analyse encrypted teleprinter messages at a very high speed. It came into service a whole year before Eniac and it made a very significant contribution to the success of the invasion of occupied France in June 1944.

I found it fascinating back in the early 2000s when I worked on C-130 aircraft that still utilized vacuum tubes in the compass amplifiers for the navigation system. Your explanation of how they amplify signals, like earth's magnetic field, helped close the gap on my understanding of that navigation system. Those airplanes used a device called a Magnetic Azimuth Detector in the wing tips or in the top of the vertical stabilizer to sense magnetic heading and transmitted a very low voltage signal to the navigation computers for heading reference. Before the signal could be utilized effectively, though, it had to be amplified. Enter the humble light bulb 💡

The first production C-130A came off the production line in 1955. I know they have had several upgrades to the airframe and systems over the years but it still amazes me that a plane designed and built in the 1950's is still in service today. The B-52 is another plane that still in service that was first built in the 1950's. I worked in PMEL witch was renamed TMDE when I was in the U.S.A.F. and I was shocked by how many pieces of test equipment we had in Germany that were built in the 1950's and 1960's and used vacuum tubes and all the wires used silver solder on ceramic bus strips for connection points. I was over there from 1982 to 1984. I was surprised when the government decided to make all the military calibration labs totally civilian contractor jobs in the 1990's.

I think it’s interesting to realize that Tesla‘s invention of the radio would end up relying on an invention of Edison’s, the lightbulb, and a discovery by Edison that he only discovered because of his refusal to use Tesla’s AC, which led to first being used as a device to convert AC to DC, Lol, and then to create another device to amplify radio transmissions and then used to receive and play radio transmissions on a radios speaker.

i know about them and have even "messed around" with them, because i work with audio/music related stuff. The audio and music industry still uses them, they can produce the same quality of audio than a transistor based system, and they have a very "unique" kind of touch added to the sound. its usually described as a warm super subtle distortion in audio that's very pleasant, and its imposible to emulate trough digital stuff. even music from your phone going trough an vacuum tube desk amplifier will sound very crispy in the most pleasant way there could be. i know it sounds exaggerated, but if you got good ears and know what you're hearing, you'll see that it's different.

The memories: In high school 4 of us tried to build a "computer" with pinball game relays. Load &slow. We got it to add, subtract, & multiply. We graduated before getting it to divide. Later as a college instructor, I built a spreadsheet to demonstrate how computers calculated. It still amazes me how computers can do anything with such a limited number of basic tricks. My head is hurting again!

@@jpisello oh transistors are covered? That’s good. I’ve been trying to learn about them/read up on them, and it’s been slow going. The only thing I know so far is that there are numerous kinds of transistors. So far, my understanding is that for turning off a transistor maybe the middle portion of the transistor gets a counterbalance of voltage to make it so that no difference of voltage exists for a current to run across the transistor. Is this the case? That would mean keeping a transistor off would actually cost energy. Do transistors have a capacitor be the key to whether they’re switched on or off? To switch them off the part behind the dielectric (of air or maybe silicon) would be made into whatever charge so that no difference of voltage exists for a current to flow across. And when they want it to turn on then they make a difference appear by change the charge.

My father was a professor at Cornell University, and I have some memories from the early era of computers. My father acquired for his office in about 1960 a purely mechanical calculator made by Friden that could add, subtract, multiply, divide, and, COMPUTE A SQUARE ROOT. It was about twice the size of an electric typewriter, very noisy in operation, and cost the then-huge sum of $1300. I also remember being taken in about 1958, as a very small child, to see Cornell's first electronic computer, running on banks of vacuum tubes and pretty much filling a former engineering school machine shop,

Ten of the twelve ordered Mk2 machines were completed and used successfully until the end of the war. At wars end these machines were destroyed and the project was kept secret for over thirty years. The last two Colossi machines (11 and 12) were shipped to GCHQ for secret work after the War. These machines were some ways many years ahead of the ENIAC computer. .
