Lol, I was actually dreaming about flying around (not to space) with a SpaceX dragon just last night... It didn't end well lol

Well, they already have the computer…

Will it blend? Scnr.

If it were used the heatshield would be toast... and the rocket part gone :-(

‘I was surrounded by stars, floating without control,’ recalls cosmonaut Alexei Leonov, the first man to walk in space who passed away this week. He made history 50 years ago on a mission that nearly cost him his life. As a celebrated artist he brought colored pencils to sketch the view of Earth. His drawing sunrise drawing is the first piece of art created in space. Blessed spaceman, rest in peace - Comrade. *Alexei Leonov, the first man to walk in space | Science | The Guardian | May 2015* www.theguardian.com/science/2015/may/09/alexei-leonov-first-man-to-walk-in-space-soviet-cosmonaut) [ Fifty years ago, Alexei Leonov opened the airlock of his tiny space capsule, which was orbiting the Earth, and stepped into the void. For 12 minutes the Soviet cosmonaut floated above our planet, tethered to his ship by a 16ft cable. In doing so, Leonov became the first person to walk in space. On 18 March he was blasted into orbit in a two-man Voskhod capsule which he shared with his commander, Pavel Belyayev. After completing one orbit, Leonov was given the go-ahead to begin his spacewalk and crawled into the craft’s makeshift airlock. He opened its hatch, slid out and floated into space to begin his mission. Leonov still remembers the utter silence he experienced when he emerged from his spaceship. “It was so quiet I could even hear my heart beat,” he told the Observer. “I was surrounded by stars and was floating without much control. I will never forget the moment. I also felt an incredible sense of responsibility. Of course, I did not know that I was about to experience the most difficult moments of my life - getting back into the capsule.” Leonov’s spacewalk very nearly ended in disaster. In the vacuum of outer space, his spacesuit began to balloon out of shape and its fabric began to stiffen dangerously. His hands slipped out of his gloves, his feet came out of his boots, and Leonov could no longer get through his spaceship’s airlock. Even worse, the craft was hurtling towards Earth’s shadow. In five minutes, the cosmonaut realised he would be plunged into total darkness. So he began bleeding air from his suit from a valve in its inner lining. Very slowly his suit deflated, just as Leonov began to notice the first signs of decompression sickness. “I could feel pins and needles in my hands and legs,” he recalled. Leonov squeezed himself headfirst through the airlock and just managed to close its hatch behind him, his temperature by now soaring through the extreme exertion of his return to the spaceship. Leonov slumped back in his seat beside Belyayev. His woes were far from over, however. First, a charge was fired to blast the airlock - which was no longer needed - into space. The explosion caused Voskhod 2 to rotate, disorienting its two crewmen. At the same time, instruments showed oxygen levels in the capsule were now climbing at an alarming rate, threatening to trigger a blaze that would have burned both men alive. Several hours passed before Leonov and Belyayev could get the craft’s oxygen levels back to normal. By now, the spaceship was scheduled to return to Earth. However, the two cosmonauts discovered its automatic re-entry system no longer worked. So the pair fired the craft’s re-entry rockets manually. This manoeuvre should have separated the landing capsule, containing Leonov and Belyayev, from the spaceship’s orbital module. “A few seconds after the firing of the engine, we felt a jolt as the orbital module separated from our cabin - but something went wrong,” said Leonov. “We felt a tugging force pulling us back! I looked out of a window and saw the orbital module was still connected to us by a communications cable. As a result, both modules were spinning rapidly as we fell steeply to Earth!” Voskhod 2 was plunging to destruction, but was saved by the heat of re-entry which burnt through the communications cable. The landing module separated and its parachutes were deployed. “We were safe,” he said. The crewmen’s problems had still not reached an end. Their craft landed 2,000 kilometres downrange from its intended target and plunged into a dense Siberian forest. It took two days before a rescue mission reached the pair, who had to huddle in their tiny capsule in temperatures well below zero. “We spent two cold nights in the forest,” said Leonov. “We did not meet wolves or bears, but we knew that there were many of them around. It was spring time and the animals were very aggressive. ...]

But if they do, they fail spectacular.

It seems they measured niobium k73.

LOL, Lessons to be learned, Right ? Boeing should have used a Arduino.

Building spacecrafts for maximum shareholder profits, good grief...

🔥🔥🔥🔥🔥

Turns out there was more than just that wrong. The screw up in the programming meant the service module would have collided with the craft after separation (when setting up for re entry). The error was only spotted after engineers went through the programming after the clock fault.

Yeah, and the scary part is that the error was in the main code... I can't even imagine the state of the more obscure edge cases, those that should save the craft in case of a rare emergency.

Tantalum are just solid electrolytics, they go bad just like their regular electrolytic brethren except the tend to explode either on their own or when they become fuses when power is applied. You'll find many electronics from the 80s with bad tantalum electrolytic caps.

@@Wingnut353 Not all tantalum capacitors are the solid electrolytic type. These ones appear to be the so-called "wet-tantalums" and they don't exhibit the runaway thermal failure mode of solid tantalums. This type is generally very reliable except when the end seals fail and they leak the acid electrolyte all over your circuit board.

I guess the only time I saw SECAM was when I took my PAL Citizen Pocket TV (ST555?) on a school coach trip to Euro Disney in Paris and only getting some wobbly vertical black and white banding.

@@dazednconfused31337 Well, that wasn't exactly SECAM's fault. It was France's weird underlying black and white system that caused those major incompatibilities.

Most equipment goes to Mr Carlson's lab, best teacher is uncle doug, but the award for most rare and unusual is Curious Mark.

That's logical. You need to set one like once in hundred years, no point in wasting panel space for mostly unused buttons.

@@MacIn173 Panel space, LOL. There is enough space there.

It actually depends. I suppose that it can be operated in a suite, whose gloves are quite thick.

Having few widely separated buttons is good. Fewer accidents and less time to acquire your target.

As I remember their clock has overflown an integer number what stopped a power supply. The time to get an overflow was around 6 month without plane reboot.

@@dimacherepovskyi8600 Because it is *that* hard to build a clock that works for more than half a year.... ;-)

Lame

That's the cheapo Boeing clock. If you want a clock that works all the time, you'll need the Deluxe model for $1.8B. (Bulk discounts available for qualified customers.)

The clock is the first mechanism that humans built and then started to obey.

Time is the most accurately measured physical quantity. Clocks are the most accurate machines ever made.

The Lavian the irony....

@The Lavian Yes, yes it is and yes, yes you should.

@@azzajohnson2123 No, it depends on the type of capacitor... decoupling capcacitors always deviate from spec by a failry large amount on the side of caution, also remember, he was measuring at 1000Hz... at higher frequencies they will probably measure closer to spec.

Не имеет смысла, схема рассчитана на советские компоненты, они сильно отличаются от западных, найти их в современной России не так уж и легко, в этих компонентах были редкоземельные элементы, поэтому подобные устройства могли работать очень долго стабильно, без сбоев. Эти платы собирали и тестировали живые люди а не роботы, платы тоже рисовались руками. Все компоненты покрыты сверху слоем эпоксидного клея, такие были стандарты качества у военных производств. Вы сильно удивитесь, но домашние компьютеры сделанные в СССР выглядели внутри точно так же, эти же заводы что производили военную электронику делали и товары для рядовых граждан страны, компьютеры, телефоны (не мобильные, стационарные с АОН), звонки (музыкальный звонок на процессоре 8080, думаю на западе это забыли еще в начале 80х) и тому подобное. Танталовые конденсаторы часто встречались в советских домашних компьютерах (существовали аналоги ZX spectrum, Commondore 64, etc.), точно так же платы были покрыты клеем, вместо шлейфов проводов, были одинарные проводки из провода типа МГТФ в виде шнурка как на видео, почему то на заводах не использовались готовые шлейфы...

Да, не получится сделать реплику с тем же уровнем надёжности, но работать оно будет, а большего от реплики и не требуется

@@simsanutiy смысл оригинальных схем тогда? И печатных плат...

@@quq_CCCP Компоненты, по крайней мере бОльшую часть, найти всё ещё можно. На Авито, и особенно на Мешке. Пока ещё не всё уничтожено гадами-аффинажниками. Но дело тут даже не в компонентах, можно и на импортной логике собрать, да хоть на CPLD. Идея реплики состоит в том, чтобы повторить хотя бы логику работы, со всеми задержками, особенностями, и всё такое. Чтобы часы вели себя так, как настоящие. Поэтому содрать схему очень хочется.

@@Vadim-zm8fn В том то и дело, что все эти часы - это всего лишь 1 плисина или микроконтроллер, точность будет не та, потому что тут генераторы и делители частоты сделаны куда качественне и откалиброванны, тогда как у той же атмеги там типа 8 мегагерц, а не совсем 8, +- несколько десятков, а то и сотен герц. Кое что - не все, что микросхемы 142 серии найдешь не спорю, это стабилизаторы напряжения, ну а дальше... Резисторы млт...

I would connect it to an ahooga horn and use it as an alarm clock. Absolutely no danger of oversleeping.

Apparently it turns the whole thing on and off. Now imagine the amount of pain Boris had to go through when he accidentally disabled the clock. :o)
