Russia's dollar tree JDAM kits had so many catastrophic malfunctions that the russian government had to take the rare step of promising fixes in the Mk II. Here it is. Brain of the new and improved УMПК / UMPK glide bomb kit. V2 on the left, V1 on the right.

v1 specimen
my personal pick for the most Eeyore-esque dud
It looks like it's trying to impregnate the bomb anon
the face is on the right
Richard Scarry tier shit. Just needs a tired expression with tongue out.
What the frick? I have a guitar pedal from the 80s with more circuitry in it than that
>serial port
SOVL
Those gps/glonass antenna are actually a rather high quality American made product, kinda impressive they used good parts for once
Are these things just like JDAM, ie, can be strapped on to any ol’ FAB and turned into a PGM?
Yes they can be strapped onto many things. No the JDAMsky references aren't accurate, just usefully familiar for many people. They started with no active guidance whatsoever and they've since been upgraded. The process has been chaotic and YMMV greatly as a pilot who has to drop these. The tendency of VKS pilots to use the glide kit purely as a stendo buffer for AD so they can lob bombs from further away has also been counterproductive. I suspect airforce command applied more pressure on pilots for closer bombing runs during the avdiivka debacle, which might help to explain the crazy aircraft loss rate.
that archived thread is really interesting
>V2 on the left, V1 on the right
I might be a blind moron, but aren't those two the same board with some cum on the "old" one?
The later revisions are very difficult to tell apart by eye. Since integrating the LM2596 they've been mostly stable, resizing the board for whatever reason and making individual part swaps.
I shouldn't call the older specimen "v1" really. More like 1.5
The braided covers look so out of place but its a subtle touch
This looks like the megasquirt board I soldered together in high school to manage the fuel injection on my Volvo 240
could be worse
>babushka employment program
>milled aluminum box
Woah isn't that expensive?
Yeah, and heavy. Makes me wonder why it wasn't just bent sheet metal or a die-cast box.
>aluminum
>heavy
Yes anon, aluminum is a lightweight alloy. But that box is still a lot thicker than it needs to be.
maybe they have a warehouse full of these boxes
Possible, but not all that likely. Those look relatively freshly machined, the surface hasn't had a lot of time to oxidize yet.
But the same principle applies: maybe they've got plenty of CNC mill time but no bending brake?
military procurement is sometimes inefficient and can yield nonsensical results? with incomplete information, occam's razor seems useful here.
Idt that they're making enough of those kit to justify that, unlike the metal-folded Kometa-B that's being 'mass' produced because they're using it in several drones including the geran 2.
I'm more wondering why they don't use off-the-shelf boxes? These kinds of things are common in industry, labs, etc:

or
https://www.hammfg.com/electronics/small-case/diecast
Shhht...don't give away those low level technical tricks.
I'm gonna throw my two cents in amd say someone high up in the procurement process owns the factory that makes these
Yeah, you are probably correct lol, I bet too, that is some relative or a close friend of someone higher-up at Rosoboronpostavka that sell that shit. This is how everything works in the russian kleptocracy system.
This b***h Nadezhda Sinikova (Federal Agency for the Procurement of Armaments), she must getting some sweet,sweet $$ in kickbacks. I wonder how many houses she own in Plyos, or how many dachas in Rublevka.
> But that box is still a lot thicker than it needs to be.
Not if you want it to deal with conditions relating to temperature fluctuations, resonance, the usual military shit.
USSR MIC was about producing a lot but cheap, even if it's shit and has bad tolerances, bit factor are actual manually operate mills and such. This model of work collapsed in the 90s because no more money, no more mill operators.
When money re-appeared in 2000s, it was impossible to replicate due to economy, demography, society, etc. A choice to fund purchase of western CNCs and such, make less stuff, with more automation, even if it means that it costs more. So yes, they'd mill a stupid box and it would be expensive, because setting up presses or die cast shit is too expensive / too time consuming / not relevant for the amounts made.
One on the right looks die-cast
Both are cnc milled I can assure you. Quality is higher on v1 as far as the box is concerned. They have run a chamfer over the edges properly.
For these things you need to make it from alu and if you're cncing a bunch of them together it's not so bad in terms of cost considering the potential value-add to already existing munitions.
aluminium is really annoying to machine
starts gumming up when it gets too hot and tends to come away in flakes and chips that get stuck to everything
...... Cooling fluid my dude. If you're dye grinding use the solid lubricant to keep the alu from sticking to your tools, but it's going to get on everything else (But is easy to clean up).

why do you guys always argue about boxes in these threads
are they unable to source connectors? those cables should end in a plug, it looks like that was the original intent as they are soldering directly to surface mount pads. if they were planning on using wires they should have through holes which would at least make the solder job a bit easier. still stupidly labor intensive. also the random through hole diode is odd. what's up with the jumper wires? the pcb looks the same, could they not get a new board at least?
no one in the chain of production has some way to grift off importing molex connectors and ethernet plugs or other worthless pieces of plastic
instead the assembling factory has been RAKING it in having some dude solder 85 loose wires and then bind them into some ghetto loom
Oh holy shit I didn't even notice that, good lord. I hope the space they're soldering these in is well ventilated.
>actual loose wires soldered to surface mount pads
holy fricking shit
by the way is this please wait before posting thing new?
I can see what look like some soldering bridges on the newer board?
Yeah, There's definitely some details here that make v2 emphatically 'theoretically' better.
>hand soldered wiring attached to a chinese pcb
really reminds me of soviet computers, where they basically got a mishmash of random counterfeit and domestic-produced parts and just connected them together with wires
this almost looks like its made from salvaged parts. I ve built a few simple boards from scavenged bits and pieces before, these components are not new.
It legitimately looks like a high level hobbyist project. Like if you go over to the drone thread on PrepHole you would see someone posting this there and it wouldn't be out of place.
Cheap matters more to the higher-ups than whether it functions.
>a mishmash of random counterfeit and domestic-produced parts and just connected them together with wires
>you can almost see the electrons flying off [/communism/] those sharp corners
what the hells going on with all the jumper wires?
Design revisions, did you not pay attention in KhTZ engineering college?
Back in the day 2D lattice programs (Or human computers) used to make these things couldn't always handle every connection, so they'd just use jumpers for the few they couldn't get working.
I've done it when I did customer laptop repairs, nothing really terrible about it on a disposable product really other than being another low likelyhood point of failure.
You don't see it on non disposables because some technician could bump or knock off the wire and it's fricked, but for one time use it's really just whatever works for the 80's and I'm whatever about it.
YOU JUST KNOW that 04 86 is the date of production.
ngl I wouldn't mind owning some genuine CCCP tech.
It's a ham radio diy project for a Soviet magazine, so, yeah.
>04 86 is the date of production.
It is yeah, its one of their Radio-86RK personal computers from the 80's, it was a DIY affair, to assemble a computer, it was necessary to purchase the necessary radio components, make two printed circuit boards and mount all the components on them. In addition, it was necessary to use a hand-held programmer to write the firmware into two chips erasable ROM , and also to manufacture a power supply, keyboard and computer case.
What you got was:
• Processor KR580IK80A or KR580VM80A (8bit, 2 - 2.5Mhz)
• RAM: 16-32 kB, ROM: 2 kB, expandable
OS RAM monitor (with RK-DOS 2.95 drive)
You can read more about how delightful it was here:

Its not BAD per se, its a better PC than the ZX-Spectrum for example, its just more of a hobbyist thing, aimed at people who want to learm more about assembly and coding themselves.
It has been remade and de-jankified by 3rd party sellers and retro hobbyists since then, pic related.
It's funny watching not just zoomers, but very late zoomers/early gen alphas realize, in real time, that people used to physically put computers together by hand. You would think it'd be common knowledge but apparently not. Can't wait until they figure out what Windows 1.0 actually was.
I remember playing Dune 2 on a 286 through DOS.
I think that's the oldest "proper" game I can remember playing. Then Aces Of The Pacific after that I think. It was a long fricking time ago.
>be OP
>be zoomer
Your scenario would be great. I fully expect most zoomers to be befuddled by anything that isn't an assembled consumer product for the rest of their lives.
Its the sort of thing that I would probably find enjoyable now, with the internet handy to help troubleshoot what you're doing wrong, but back in the day it would have been a complete ballache to figure out that you'd mounted one component back to front.
Not bad for DIY actually. I think it was published in "Cдeлaй caм"
This is neat: https://github.com/skiselev/radio-86rk
does anyone else see that big hole in that gray chip on the left image? that looks like a parts failure to me.

The soldering looks like shit
Lockheed Martin is shaking right now
Very typical Russian board layouts
>Western boards
Components are laid out in the order of systems are logically built out
Power -> Main CPU -> Auxiliaries (USB, sensors, etc)
All of the runs are hand optimized
>Chinese boards
All of the components are thrown on there at once and as tight as assembly machine tolerances allow.
All of the runs are auto routed and make no sense to the human
>Russian layout
Components are grouped by similar type, boards get really big physically to compensate for bad run layout. Everything has to be manually routed because of the weird component placement.
Which electronic parts came out of the washing machines?
>No western counterparts
Lmao, they went from tie-downs to some sort of paste for holding their wires down. Must have had an issue with the wires coming loose
I would love to see a piece by piece comparison of a Iskander and a KN-23, i fully expect the Nork missile to be of better manufacturing quality.
why are there suddenly 5 threads on FABs?
Fun, isn't it?
people are asking stuff like "can I get a qrd on these?" in the other threads, too. electronics thumbnail = invisibility cloak kek
Oooooh frick no chamfered edges on those tapped mounting points on the V2 box. My boss would have my head. Also I think V2 hasn't been cleaned out very nicely for assembly, unless that's just fibres from the cable insulation.
