It’s part of a joint for the handle of an electric snowblower I have. It’s a cool looking part for sure, but it was easy to recreate as a model to print.
But after breaking the original injection molded glass re-enforced nylon and 3 other home printed parts, I redesigned the joint to be a single piece solid part. So while I can’t fold the handle down for storage, it no longer breaks.
I paid $35 delivered from Russia. And honestly, I do not remember if that was a sale price or not because it’s been enough years ago now.Despite all the cheap quartz watches found in Walmart, $140 really isn’t all that much for a properly made manual wind watch these days. Even a plastic Timex will set you back nearly $120 for a quartz LCD with 24 hour display and only one choice of looks. So I probably wouldn’t consider the price out of line for the Komandirski with multiple choices available.
A Bespoke 24 hour mechanical movement would be quite the piece of horology art. A conversation started indeed.
Or if you can scrounge up a guitar string, you can simply make your own coil spring from scratch.
Even the French figured out that decimalized time was stupid after a couple of years.
Which has added credence to the old saying that “The French follow no one. And no one follows the French.”
They don’t have to be expensive, though such watches are less popular for everyday use. In fact I’m wearing a Vostok Kommendurski with a 12/24 hour dial. When I was a medic, I needed to record all my times in 24hr format on my run reports. I think I paid $35US delivered from Russia 15 or so years ago.
And no extra gear is needed to make an analog watch/clock indicate 24 hour time. Time doesn’t change. You simple have one scale that reads from 12AM through 12PM and then at the next hour, (1PM) it simply gets renumbered to 13, 14, 15, 16 and so on until you reach 24 on the inside scale. Easy peasey.
But it is possible to build a watch/clock that the movement does move in 24 hour time and you would be correct it would a couple of extra gears to accomplish. But, it would also be a real pain to create a legible watch face with all those numbers on a reasonable sized watch. Far simpler and easier to print the two scales on the face and call it good.
All work done in FreeCad.
My favorite personally reverse engineered part
And a favorite design I use every day a holder for my loose tea strainer to catch draining water
I had a 486DX running DOS for writing and editing CAM programs for CNC mills, lathes, pipe bender, and a laser cutter. And for funsies, an even older Macintosh that booted from a 5 1/4" floppy that ran a CMM, (co-ordinate measuring machine). And the software for the CMM ran from another 5 1/4" floppy.
This was about 2017 before I retired as a toolmaker.
Thanks for pointing that out Captain Obvious. And I earned the tee shirt for needing to make that decision-- more than once.
If you buy software at a version point, (vs the subscription model), why would you expect an update for it? Particularly for free? You chose to buy at a frozen point.
For all the times I have done CPR or those times I have to deal with a major trauma, never once did I see Jesus there waiting to take a turn at chest compressions, I never once saw the Holy Ghost crawl into an upside down car wreak with me, and God sure as hell was not there when I had to scale up out of that 20ft deep drainage ditch and had to explain to a Mother that her 11 year old son was dead under that 4-wheeler and there was nothing anyone could do to fix that.
God ain’t never had anything to do with it.
So why do we do CPR? Why do we use AEDs? Was all the CPR I have done a waste of time?
Dead means you are going to stay that way. Dead is irreversible. And until I and/or a doctor say you are dead, you are not. You are just maybe dead.
No it’s not. It only becomes a criteria when you can no longer reasonably be sure that it can’t be restarted.
Source: Retired medic that has pronounced my share of dead people AND restarted a few hearts also.
As an old and retired medic, the lack of respiration and pulse doesn’t mean you are dead-dead. On the scale of "Not Dead to Dead-Dead, a lack of respiration’s and pulse means you are at the maybe dead on the line. And other factors will make the final determination about if you are actually dead or not.
The first determining factor in figuring out where the patient is on the scale, is if you make it into my amp-a-lamps or not. If you do, you are alive at least for a little while longer and I’mma let the doctor sort it all out for you. If you don’t make it in the back of my bus, then you are dead-dead and nothing can change that-- not even god himself.
As an old and now retired medic. My personal definition of dead was if you made into the back of my amp-a-lamps or not. If you did you weren’t dead-- you were merely having a bit of a bad day. I might have needed to do your breathing for you and I might have needed to make your heart pump blood. But until some doctor somewhere decided you weren’t worth his time and effort, you were still alive. Because I don’t haul dead people.
So, by my definition as a trained and professional medical person, you where never dead-dead. Just someone have a bad day among many others having a bad day at that time.
It’s a good thing that the lack of a heartbeat isn’t the ultimate definition of dead. But it can be one of the markers of dead.
This is truer than you know. Well, the killing a polar bear part.
When Eskimos really got modern metallic cartridge firearms post WW2, they for some reason decided that the .223 Remington cartridge, (precursor of the 5.56 NATO round), was the best thing ever to hunt with. And you can be positive more than one polar bear got itself killed by the mommy of the the 5.56 NATO. And a bolt action rifle in .223 remains popular with them to this day.
Close enough that we probably helped bred them out of existence. Neanderthal genetic markers show up with some regularity in certain modern human populations.
Edit to add: While humans didn’t breed them out of existence, we certainly did intermix with them. And that does help to maintain their existence yet today.
There are enough of them that I no longer go in certain areas of the forest unless I’m armed. And I always have 2 arms on me at all times.
In that kind of cold, body mass matters for keeping warm. You need to be bigger to survive and they aren’t really over powered for their environment.
Well, beyond the sheer social resistance to the idea. Turns out everyone needs to agree it’s a great idea and almost no one did. Evidently humans are wired to the base12 time format far better.
The attempt at switching to base10 time quickly fell apart when people started notice that the the “time markers” were starting to drift. And at some point they finally figured out that what we call “noon” was going drift rather quickly to not happening until evening and therefore Monday was going to move to a different spot also. This is a very bad thing. Because any kind of calendaring system needs to be as consistent as possible. Noon must happen at the same point in the day every day or as close to it as it it can mathematically get. If it drifts to fast and far, then it’s a worthless marker for time. And decimal time has that problem in spades.
Now, no calendar system is perfect because the orbits of the planets in our solar system isn’t perfectly consistent. Sometimes the orbit of earth is a tiny bit faster or sometimes it’s a tiny bit slower. So we strive to get a close as we can but we still need to make adjustments. Turns out, all that math is really bloody hard.
