Well … I should probably start from the fact, who the heck was Dzokhar Dudajev.
He was not a terrorist as imperial Russians think. He was the Commander of the military Airfield in my home town. He had nukes on his disposal. And he did not use these. But, at some stage, he acquired a crazy idea that Russians will donate freedom to his home country and little nation. Which, of course, was a cruel mistake. Russians never give anything for free, except the sodom phuck. Thus Russians determined the coordinates of the Dudajev’s satellite phone and destroyed him by means of a laser guided rocket weapon (or two). And, after Chechenian people had lost the leader, Russians somehow succeeded to call all the Checenian people as terrorists (which they certainly are not). Actually, this was not the first time when whole nations were called terrorists. Russians are damned war criminals … but this is story for another blog: http://www.crimesofwar.org/a-z-guide/chechnya/ .
Last but not least, Hotel Barclay has the Dudajev Suite. Go and visit.
Well. What has this all to do with the Russian Art of DIY? Oh, it’s very simple. There is a Bloh Market now on the territory which 30 years ago was the repair yard for the Military Air Fleet. And this is the device I bought there for 10€:
M286K-M1 is a very special indicator – it has “Low” and “High” sense contacts. Actually, the left and right regulators are meant to define the minimum and maximum values of the indicator. When “Min” or “Max” reached, the contacts are joined. A magic of a Russian electro-mechanical miracle.
The unit was relatively weighty (which meant it had a big transformer inside). Thus, I bought it.
This is the inside view of the device:
DIY was a lifestyle during the Soviet regime. Many people did DIY as a hobby. And, what is very natural, military people did it. Even at a nuclear airfield. How do I know for sure this device has been built by some Russian military ppl? First, the soldering quality. And then, the extremely specific military parts are used. The relais in this device are of strictly military origin – they were only used on Russian military aircrafts (27V DC):
It was absolutely impossible that someone except the military servants had the access to this kind of parts. Could be, these relais were screwed off an old decommissioned Tu-16 plane.
The device most probably was meant to recharge the accumulators. The transformer used, is from standard (tube based) Russian TV-set. Three LEDs on upper side, two of them are 2-color ones. Note the tube style! Actually, not much to explain. Let the pictures speak. I dismantled the device and rebuilt as a usual power source to test the PA’s (2x 11,5 or 15 or 17,5V).
Note the soldering quality! Match it … if you can 😉 I am still trying … last 40 years 😉
Much probably the device has been designed and made in as a single workout, approx in 1985-1989. How I know about the year? Note the clones of western DIN connectors on some of pictures above. These only appeared in very late 1970’s with the emerge of small compters.
And the last picture – do note the repairability! This kind of things do not happen accidentally. Die Deutsche BauArt – once imported into Russia;)
