The TV remote worked using ultrasonic waves. When you pushed a button, it would hit a bar (tuning fork), and the inaudible sound would control the TV. It made a loud click when you pressed a button, and that's why we called them "clickers."
These are great and I like when Max reacts! Two things struck me in this. I'm 53 and was born to older parents. My dad had a slide rule and when he passed away, none of my siblings wanted it so I inherited it. My dad graduated high school in 1949, served in the the Korean War and then came back to the States to study electrical engineering in the mid-1950s. He studied tube electronics and told me that the science started going over his head when transistors came in (he ultimately changed majors and went into elementary school education). Imagine studying electrical engineering before computers or calculators! Everything was done on slide rule! He was really good at using it and could derive answers almost as quickly as using a calculator. I'm now a professor and one of my students expressed interest in slide rules. I surprised him in front of the class when I gave him my dad's old slide rule from the 1940s. Second thing that caught my attention was the typewriter eraser. I remember seeing one of those in my family's desk when I was growing up. That was a large eraser (like a modern day pencil eraser, except flattened into a disk) and the brush at the bottom was to brush away the debris after you erased with it. I just thought it was an old-time eraser and didn't realize it was used for typewriters. We were using white-out when I came along in the 70s and 80s.
Zenith space command remotes came out in 1956, that version is from the 70's. It works on sound, no batteries or lights, it's why people refer to the remote as a "clicker". The first remote to control a television was developed by Zenith Radio Corporation in 1950. The remote, called Lazy Bones, was connected to the television by a wire.
The gyroscope once spinning can't be moved off its axis. The faster it spins, the more force it takes to move it. Missile guidance systems, space craft, and many other things use these to stay on target/course.
NIce! I had a hard time on several of those, like that typewriter cleaner (i thought it was an eraser) and that toaster (it must be like 100 years old) - Mike was holding back I think 😆
I'm 61 and knew every one of those, so I know I'm getting old. That old TV remote reminded me of something: I bought our family's first VCR in 1981 when I was 18 (summer job earnings) and it came with a corded remote!
I remember working in an office after leaving school and you’d often get people phoning the fax machine by mistake (you could hear them going ‘hello? Hello?’ 😂
A slide rule was used for calculating numbers, often by converting decimal numbers to a logarithm, adding them and converting back to get a multiplied answer, but also for other maths.
The only one that defeated me was the typewriter eraser. There were still typewriters in use when I was a kid, but they either had a correction ribbon, or you used Wite-Out (Tippex).
Try to sell something with the word "mangle" in it, and I doubt many would buy it, let alone put their clothes through it. I always thought a "Laundry Mangle" was what happens when my chick's bras wrap themselves around the washer agitator, and I have to untangle the damn things.
@@peensteen You use a lingerie bag for that. Bras go in it, and throw in washing machine and bras are always hanged to dry never in dryer, Your gf should know that.
@@Blondie42 An abacus is more primitive. Slide rules were used by NASA in the 1960s before calculators became commonplace. Slide rules could do everything an abacus could do, plus trigonometry functions, exponentials, and logarithms.
Calculators existed for decades for business work, but the accuracy of decimal places was often limited unless a very expensive machine was purchased. Also, keep in mind that manual calculators existed before electronic calculators. Calculators were used for launch trajectories on the ground, however they were limited to arithmetic. Slide rules could calculate arithmetic as well as trigonometric values and were flat thus conserving space.
the typewriter eraser, the round orange thing was the erasure, had to be thin so you could erase one letter, then brush away the ink you erased. Nice Daz on the Hauk Tua.. She is though a bad sentiment on our upcoming society.. She is now selling merch with the saying, was on stage at a concert. You should try to look for a which came/ made first type video..
