Late 1970's air defense command and control systems consoles (a thread about some of them will come eventually).

1968 soviet ground based ELINT system antenna setup. It deals with needing to cover a wide range of sub-bands by simply listening to all of them at once via separate receivers. (this whole setup would be typically truck mounted on a rotating assembly)

General principle of R-60 missile IR seeker operation. This is very similar to majority of cold-war era IR AA missiles. A spinning mirror system projects the IR signature through a static modulating disc (example in prior post), the remaining signal is then picked up by a single

1PN22M1 sight complex diagrams. (used in BMP-1 and BRM-1K)

Olimp MPK-005S, a late soviet high end reel-to-reel tape recorder. A very interesting machine, largely unknown and poorly documented in english language. Expect some follow up posts about how it works and other interesting soviet/WP consumer electronics from time to time.

Very intimidating cockpit instrument mechanical diagram (PNP-72-14)

If your aircraft prototype does that during testing please contact your OKB immediately.

Su-27 conformal fuel tank jettison test (wind tunnel)

Kh-31P seeker

14 element cross array detector inside KOLS (MiG-29 IRST system). The detector components are made out of PbSe and Peltier cooled to -80℃ or so.

Some people may have heard that microchip designers have a tradition of putting small drawings in leftover blank spaces of the chip, but I don't think many have seen soviet examples of this. A small hammer and sickle etched in the corner of a 1980s 20-bit micro-controller chip.

The general layout of mechanical/optical system inside KOLS (MiG-29 IRST). It is rather complicated.
