The pictures on the nightlight represent the milestones in the history of the USSR. Very symbolic :-) I'm not sure if I got all of them, but here are at least most of them: * Lenin: the founding of the Bolshevik party (early 1900s) * 1917 and the ship: the October revolution, the signal for which was a shot fired from the cruiser Aurora (pictured) * horse riders: the civil war (1917 to mid 1920s) * tractor: the collectivization of the agriculture (late 1920s) * electric station: electification and industrialization, and specifically DneproGES (1930s) * figure with a page and rifles: the start of Great Patriotic War (WWII, 1941), more specifically a copy of the wartime poster "The Motherland Is Calling!" * sword breaking the swastika: the victory in Great Patriotic War (1945) * houses: rebuilding after the war (late 1940s) * ship: the first atomic icebreaker "Lenin" (I suppose, 1950s) * Gagarin:the spaceflight (1961) * Kremlin: 26th Assembly of the Communist Party (1981, this dates the manufacturing date of the lamp, between 1981 and 1986, when the 27th Assembly happened) * people with an atom symbol: symbolizes the future scientists It's interesting to notice that they haven't really found any notable events in the 20 years after Gagarin. It's also possible that the lamp was manufactured since 1960s, with the Party Assembly number changing over time. And a fun fact about the 26th and 27th Assembly: the typewriters in the USSR were obviously Cyrillic and lacked the Latin letters. Instead the Roman numerals were typed as similar-looking Cyrillic letters, and also the digit 1 was shaped as I. So XXVI and XXVII were actually typed as ХХУI and ХХУII. Which looks very similar to a rude word in Russian, and was a source of laugh at the time.

@@ananozytrgx Что, молодое поколение уже не узнает всю эту советскую символику, которую в нас вбивали? Ну, это наверное хорошо. Краткая история СССР в картинках на лампе: * Ленин - основание компартии (1900-е) * 1917 и корабль - крейсер Аврора, выстрел с которого подал сигнал к революции * всадники (буденновцы) - гражданская война (1917-20е) * трактор - коллективизация (конец 20-х) * электростанция (ДнепроГЭС) - индустриализация и электрификация (1930-е) * женщина с бумагой и ружьями - начало Великой Отечественной Войны, плакат "Родина-мать зовет!" (1941) * меч разрубает свастику - победа в ВОВ (1945) * строительство - восстановление после войны (конец 1940-х) * корабль - первый атомный ледокол "Ленин" (видимо, 1950-е) * Гагарин - космос (1961) * Кремль - 26-й съезд КПСС (1981). это нам дает дату изготовления лампы, между 1981 и 1986 (когда прошел 27-й съезд) * люди с символом атома - учёные будущего Интересно заметить, что они не нашли событий в 20 лет после Гагарина (см. "застой"). Или возможно лампу изготавливали начиная с 60-х годов, меняя только номер последнего съезда КПСС, это было вполне типично для СССР. Забавная история про 26 и 27 съезды: В советские времена на пишущих машинках не было латинских букв, поэтому римские числа изображались буквами кириллицы, и еще цифра 1 выглядела как I. Пишущие машинки использовались повсеместно,в частности всевозможные пособия и инструкции тиражировались с машинописного текста. Любой документ начинался с восславления решений последнего съезда партии. Так вот, 26 писалось кириллически-римскими цифрами как ХХУI, а 27 - ХХУII, похоже на понятно какое слово, над чем много смеялись.

@Dragomir Ronilac In 1917 there were two of them - in February and in October. The first one was a revolution that had overthrown monarchy and the second one did the same with the provisional government. Of course by official soviet doctrine first one was called the February Bourgeois Revolution and the latter celebrated as the "real" Great October Socialist Revolution. In many cases the February revolution wasn't even mentioned in USSR and most people were taught that Lenin had overthrew the Tzar himself.

Just brilliant, thank you for making this series.

If one day you gonna stop this videos coming i will never forgive you Marc.

The circuit at 3:27 is a blocking oscillator. In that configuration it would oscillate freely, sending pulses to the secondary winding to be read by the digital gate.

I was an electrical engineer briefly in college before moving to mechanical so much of this goes over my head but it still fascinates me. Worth every penny I send and every second.

At 6:59 this is not actually a Karl Marx picture. This is a Great Patriotic War era poster "Motherland calls". The next on the right is the sword breaking swastika, i guess from the Soldier-Liberator statue in Berlin.

thats a very 3:26 common circuit found in space electronics i basically use it daily in my designs but also with just two winding that also works. Very simple and good for isolation telemetry signals in Space electronics

I agree. It's a blocking oscillator.

Very interesting video. The clock is quite complicated in details. In the mean time, I recently reverse engineered a clock from Boeing 747, P/N A15808. It used filament displays from Wamco while also had an electromechnical stopwatch. The clock used no MCU either, but a bunch of CMOS SSI and MSIs. It doesn't have internal timebase but requires an external 60Hz input. What's more interesting is that the clock has timestamp output as RZ code, which I guess most probably would be used by the flight data recorder or transponder.

@Derundurel

4 жыл бұрын

The RZ code is probably ARINC-429, common on aircraft even today.

Question is if you start it with the front panel, will the external start control stop it, or will it reset it to zero and then start counting up again from zero. Same if stopped from front panel, will external start control do the same. The clock requirement is not too strange, given the transformer coupling, you would have your 2Hz signal driving a relay in the timebase generator, that then gated the local 28VAC 400Hz bus, to give a tone burst to the clock, so that any faults are easy to detect just by listening for the tone using a capacitive probe near the clock wiring. Relay of course, as those little avionics rated relays are small, and will easily do a million cycles at 28VAC 50mA of contact current, and the coil probably was driven from a 2Hz 5V logic level, likely switched by the Soviet clone of a 2N2222A transistor. IIRC relay part number was EBDC28V22-5 for the 5V coil variant, I changed many of them. 28V rated, 2 changeover contacts, 5v coil, in a soldered hermetic case, and coil voltages were 5V, 12v and 28V, with the coil in the higher voltage ranges being wound with enamelled nichrome wire.

6:59 - There is a poster from 1941 "Motherland is calling!" 7:01 - "This means sometthing" - Of course it means victory over Nazi Germany. It depicts a sword over the wreckage of the swastika.

It's the perfect egg timer !!

Would those external inputs have been signaled from the ground by radio, or by some other sequencer/timer, or engine control system just to display duration of a burn, or what?

No Lap Display on the Stop Watch! I would have included that so you can see how much your orbit time is (even though ground radar gave the crew the time more precisely down to 0.6 seconds (as entered into the Globus).

400 Hz had to be expected somehow: it's pretty common in aircraft avionics. I wouldn't wonder if other parts in the spacecraft, especially gyros, derived from aircraft parts. Some parts in the Apollo spacecrafts had that history. I see no reason why the Soviets didn't do the same.

@SeanBZA

Being Soviet I would say 500Hz, as a nice multiple of decimals, plus you can shave a few grams off of the mass of the core and copper for the same power. As it is generated by a local inverter set off of a 28VDC bus and battery, and not by any sort of rotating equipment bus, using a higher frequency would be simple. avionics standardised on 400Hz because that was easy to attain off a rotating piston engine PTO gearbox, and was within the limits of the steel cores of the times, so it got baked in. Anything from 380- 440Hz will work frequency wise, the avionics that uses it for signals always uses a sampling clock derived from the reference signal. Fun thing is the external power connector has a protection relay, that disconnects power if the external AC bus frequency or voltage is out of tolerance. Unfortunately the protection circuits are powered from that external bus, and one user found out the expensive way that plugging in 50Hz mains did not activate the protection relay to disconnect that AC input bus from the avionic busses.
