After a while the ticking becomes monotone, and you sleep like a baby. Up there, i'd imagine it even gives a sense of security, the "symphony" of mechanical beats, the pulse of the ship.

These clocks just look so damn beautiful.

It will be interesting for you to know that until recently (and maybe even now) the control system of the metro of the city of Minsk (Belarus 🇧🇾) uses an electromechanical system for synchronizing all clocks at metro stations. It is arranged as follows: the radio signal of the exact time is received by a specialized receiver, from which the relay output goes to the control clock, and from them to the rack with more than a hundred electromechanical clocks, similar to the space clock in the video, only a little simpler in design and which allows you to adjust the time for each station, taking into account the transmission delay from the length of the wires. An electrical control signal from this electromechanical clock is sent to each station. This allows maintaining the accuracy of readings of all several hundred clocks at all metro stations in 1 second, despite tens of kilometers of wires. And at the stations, electromechanical clocks only for industrial use (with a large round dial) are also used at crossings and electronic ones to display the time of the train movement interval. And only on the new, built in 2017-2020, the third line of the Minsk metro, everything is done using modern technologies, computer control and fiber-optic communication lines.

It is interesting that the clock was still used in the Buran. Obviously it is easier to read and more intuitive to operate. Nice Video!

Beautiful mechanism. Very nice!

The start of the chronometer not being immediate makes perfect sense, when you use it for maneuvres, as probably one cosmonaut was in charge of the burn and the other (most likely commander) in charge of timing it correctly. (Just an assumption.) Gorgeous video as always.

Crazy to think someone thought flat head screws are the best choice for this job.

This electromechanical clock has another very significant advantage - it is not afraid of cosmic radiation. And they will tick even when radiation from a supernova explosion destroys all living things around.

Very, very nice - thanks!

That clock is so sexy. Maybe a kickstarter should happen to make a reproduction. Have the option for relay driven or more modern movement that makes quieter ticks. And it would join wifi to sync with an atomic ntp server.

Very cool metronome!

Nice balance to the layout of that face.

Okay, basically, this is mainly a beatiful (and loud!) watch-face. What really made it tick? Newer model had internal and external source, this one obvioulsy had only external source. What was it? Was it same or simmilar to external source for newer model? I guess "Buran" got it because of readability (because cosmonauts are further from control panel).

@biohazardousBiker

Good question. maybe the advantage of the digital clock was that it had it's own backup timing. I also would like to know.

The loudness of the clock must have been reassuring to the Cosmonauts because timing is everything in space flight. Whilst the clocks still ticking, the heart & brain of the spacecraft still lives. No ticking = no timing = don’t know when we’re supposed to do something !

@ReneSchickbauer

3 жыл бұрын

Yeah, in this kind of situations, a sound going away is much more concerning. It's the same for the life support equipment. Cosmonauts get used to the noise of the fans and pumps in their many months and years of training. It's when the noise stops that they get very worried.

It would be awesome to have something like this as a live stream. Anyone in a different time zone could just scrub backward on the stream until the time on the clock matches. 😁

2:07 В детстве, в нашем доме был такой ночник - в виде ракеты!!! Куда же он делся... Может это он и есть?)

Interesting decision in the design, they took the solenoid path for the ticking, instead of a synchronous motor. I wonder if it there is some other requirement behind.

A wristwatch version would be a dream

The guard at the mode switch looks like you could have the index finger in it, when pressing the mode button. But with gloves that would be impossible.

What duty cycle did use use during this testing? Does the rhythmic pattern of its clicking depends on the duty cycle at all? If so, feeding it with 50% duty pulses should give less annoying clicking, I presume.

I wonder if the constant clicking of the solenoid(s) ever drove any Soviet space crews mad? Possibly they were subjected to an extra loud version of it in their training. Cool video. I'll bet they were happy when the clocks became digital.

That's cool, but very loud.. Great video!

I have seen a Buran in a museeum nearby.. one with normal jet engines made for atmospheric flights only to develop the flight computer systems... you can enter parts of the ship and look in the cockpit, the "loading" bay was full of test equipment and fuel tanks.......when you see that russian technology, the wiring, ect, it is so hard to believe this every worked...it looks like it was made 150 years ago..if their real space crafts are the same, it´s a miracle to me that they work
