I have one of these lamps, I’m proposing on putting it up on my house.

People will still call it a light bulb despite not actually needing a bulb making that term redundant.

Thanks for the wonderful and informative video!

Knob and tube is not something I'd use as an example for "things built to last". I've dealt with enough old wiring to have seen how terrible the stuff ages. Crumbling wire coverings or wires just breaking off altogether.

Were there any mobile ones where you could walk around and listen to music or talking

I know many might not be able to answer this question since this is super old but does anyone know what the first speakers were called, I’m building a coil speaker but want to know how the first one worked

Bonsoir Salim ! C'est a peu près ce couvercle qui va avec le tube que tu as mais plus petit ! Bonne nuit !

I wanted to learn about how the CRT's where the data was written, as was the case with the latest Tektronix models in the 80's, but I can't find any video that talks about it.

To think we have had e.v. auto over 100 years is wild ...also incredible to think we have had hydrogen cars , h20 cars and even some cars that run on compressed air ..

Very good explanation!

Excellent

Ok

Time is only a measurement. It has 0 properties

so it's possible to have "micrometer" accuracy , but here you joe public schmucks only deserve 3m resolution.

Awesome video!

Why not 6 or 12. The answer is, the complexicity defeats the economics

Still don’t understand how they originally ‘captured’ sound. must have felt like magic at the time.

Same can be said of Einstein.

My cat only fetches bottle caps while in my room, never taught her, only just kept throwing it and holding out my hand, eventually she would drop it in my hand consistently and it was pretty cool

FINALLY I NEEDED THIS!!! Everyone with those fancy cameras that barely show much. An animated drawing is perfect.

Great fishing over there

Good video! but it would of been nice to sort of explain why ballast burn out and if it is better to leave them on continuously or cycle them off and on

I like you vidéo.

Thank you for this! How did the compass actually adjust the rudders, though?

Did this go anywhere

I have electrons in my balls too.

THE PHOTODRAMA OF CREATION was a feature length SOUND documentary film made by "Johovahs Witnesses" * in 1912. Sound was recorded on phonograph records and was mostly Voice 0ver to motion picture with some colored slide segments. THERE ARE SOME SECTIONS WHERE Charles Taxe Russel IS LECTURING AND HIS FACE IS SEEN. On KZbin, in various footms, full restorations of surviving footage or various segments or highlights. The full phonograph sountrack sirvived** but There are gabs in the visuals. * 0fficialy called Watchtower Bible And Tract Society. **Sound is on regular 78rpm recirds that were made by Cokumbia records.

The Watchtower Society (aka "Jehova Witnesses" made a 2+ hour long film callef THE PHOTO DRAMA OF CREATION in 1912

It was a nice explanation

My special needs son really likes antique automobiles 🚘 like that one he says they don't make them like that anymore but wishes they would or will someday again.

Is the Malta he's referring to Malta, NY? Not far from Schenectafy? My uncle was a manager in R&D in Schenectady for GE in power distribution engineering for many years. Dr. MVK Chari is his name. He's in hos 90s now.

Why 3 and not 6 or 12? 1) cost, 2) as Shakespeare said, 'Tis good enough, 'Twill do."

There is something very charming about that animation. Why can't we go back to that.

Fuck what video, made my life complete. Watched 100 videos on welding till now and didn't learn as much as i learned just from this video. 🫡

Most informative video on what an Arc is. Classic old school never fails. ❤

These looked rather elegant from a distance with the glass globes. If you ever saw the mercury lamps, they were useful, put out a bluish light and were ugly lamps. However, I just have to wonder how respectful some people would be if these arc lamps were put in wide use today as far as vandalism?

We were smarter back then.

Great

This mans voice is a cure for insomnia. Jeez.

Dont forget to use Eye protection while watching

Y not 2 then?

i don't understand the circuit. why are the leds direction dependent?

why not 4 phases though? lets say phase one is sin. phase two is cos. phase 3 is negative sin. phase 4 negative cos. this leads to no voltage dips, and due to phase harmony, instead of 208v when using one against the other, you have 240v exactly double.

Is it okay to play the brown wax and moulded wax cylinders on these machines?

They still make high pressure sodium bulbs and low pressure sodium bulbs sold on Amazon ❤

WOuld playing a 4 minute cylinder at 2 minute gearing ruin the tube?

National Grid in the UK wasn’t completed until 1935 so where did all of these people get their electricity from? They have their own power station or is it piece of jigsaw missing?

Wonderful looking car HOWEVER, the right front axle is bent.
