I still ask myself, why....

https://www.eevblog.com/forum/repair/cheap-clock-repair-why/

That was an interesting thread and I think you you did a good job - happy wife, happy life.

I had no sentimental attachment to this piece of junk (no reference to any wife, ex or otherwise) and I only wish I could remember how much I paid for it - my guess is no more than $5-$6. I suppose I should have put it back together and given it to some starving student whose cell phone battery needed replacement and apple watch got stolen.

I was ready to put it back up and stopped myself. It never did work well and, unlike some wines, I can't believe that 20+ years of ageing would improve this. I disliked having to manually correct the time and it was not particularly ornate in any way. Time to treat myself to an $18 upgrade - living the dream eh? So, hopefully the receiver to Colorado (and it touts some DST switches) on the new one does work and it is as good as it looks online.

Lots of entertainment for such a limited subject.  I have taken apart quite a few of this type of movement and the number of minor variations on the basic idea is actually kind of impressive.  Why bother looking?  Standard answer, the same curiosity that led me into an engineering career.

While I have several times contemplated programming up a micro to do some fancier functions than these things do, i just keep buying one of these movements when I want to make a clock.  They do the job very well.  In my experience they are usually accurate enough to last until the next daylight savings time forced adjustment and they are far cheaper than the pieces I would have to buy for functionality that isn't that compelling.

So happy that I could be the source of entertainment for you. I have lots of material :)  When I searched on that little clock box, I found hundreds of examples and was in the process of trying to locate the patent on this one.

One thing that I do want to comment on is your statements

Now, I am not trying to insult you and I trust you know that I would not be too subtle if I were, but those statements whether intended or not, really illustrate to me, some difference between an EE and a Behavioral Scientist. Now, I am happy that curiosity about anything captured your focus, I always am happy to hear about that, assuming the curiosity was not about unscrupulous activities.

I was going to throw the clock out. It was old and crusty and somewhat yellowed. Yes, I did fix it (if you call identifying some oxidation on a contact and cleaning it off, fixing), but that was not going to rejuvenate the age and I did not care to find out if it lost even more accuracy. My point is that such an experience, for me, was driven by a simple curiosity that I have had all my life about anything and it would never inspire me to go into EE.

Instead, the pathological  behaviors (my opinion) of folks who become keyboard warriors believing that they are operating anonymously is just one of a kazillion aspects of human behavior that inspired me to go into and stay into the Neurosciences - something I have never regretted over decades of work which I call the best work a person could have - trying to understand the nervous system.

Hey, different strokes for different folks - just saying and, of course, it is what it is :)

Sorry my response.offended you.  Have a nice day.

Oh come on, do you really think your response above the handful of crap I read (e.g., this circuit is resistant to pulse width - I know because umm I designed it and here is the link and I'm really a big deal so just believe me and act like I know more than I do). Your post, in contrast, was nothing like that. I think you were just trying to talk about what fun it is to be curious and how it inspired you to pursue a career in that field.

Nevertheless, I think it is important to stand up to weapons-grade arrogance and delusional SME without any demonstration of commensurate accomplishment AND factual basis with the issue at hand. People secure in what they know and what they don't know, do not act that way and in my experience it is a meaningful predictor.

That a small group band together and like each other's posts and rely on the royal we and a bunch of well know and quite tired defenses does not bother me at all - they are not used to being taken to task and rely on one or two sentence replies in hope that someone will come around to save them and then they flock to liking the posts - it is expected. They can't stand up for themselves so they just make crap up.

These are folks that I have now blocked and I am happy to do that. It is a great feature because they have little to offer me and are, in my view, recalcitrant. Yes, pathological behavior has always interested me but sometimes an asshole is just an asshole and when they are so simple to predict, having to see all that crap is little more than a waste of time. Now, I don't always know somebody's reputation on here from their nickname and have to refresh my memory, but I don't ever remember seeing such arrogance from you and I have no reason to not engage.

If you sincerely think that you offended me, please know that you did not. If I offended you somehow, even vicariously, please also know that I am not apologizing for anything that I wrote - I meant all of it (well, save some typos and grammar) and nobody is forced to read any posts let alone respond to them.

You have a great day also.

I have to sincerely thank you for that as it is the most that I have laughed in at least three days. I have no idea who you are and don’t ever recall discussing anything with you or even reading one of your posts other than this one.

Yet, in a thread that I started, you post, quoting, literally, hundreds of words. Not just mine but from another poster as well….and your contribution: A single emoji.  There is no editing your way out of that.

I think it is absolutely fantastic; I already sent it to a couple of friends.

It is as though you are holding up a sign that says “Sycophant with lips looking for butt to kiss” or maybe “C’mon guys, can I be in the club, can I, huh, can I”.

If you are trying to get me to put you on an ignore list, you have got to do much better than that. I can’t in good conscience ignore someone on the basis of a single emoji, it’s just not right. You have to use your words and not just an FU. There have to be more words than that, strung together in a sentence. Maybe even use two or three sentences. Aim high.

Now I’m not making any promises, but if you can make a really snappy comeback, I will at least consider it because; I believe you have potential - you just have to apply yourself.

I have a couple different analog clocks and replaced the movements with some that have WWVB receiver built in so they set themselves and keep excellent time.

That is encouraging. If I am to believe Amazon, I will have it very soon and will, of course, test out whether it can receive. It really only needs to do this every few days or even less often than that.  As I mentioned, I do have an old wrist watch (with outdated DST code) that does, occasionally get reception so I know my location is not out of the question.

Were the modules you got strictly for clocks? I have, on occasion, thought about getting something that I could interface, e.g., https://universal-solder.ca/product/canaduino-60khz-atomic-clock-receiver-module-wwvb-msf-jjy60/ This is probably more of a vestigial desire from reading Popular Electronics years ago and marveling at the receiver projects, rather than a real need although it would be kind of cool to have my own local time server. Yes, I know I can go through my router and get to NIST – done that lots of times.

not unlike your inability to understand that you alone are not the only one who understands that a 6501 is not the same as a 6500/01 as from your missive from a few weeks ago.

I didn't think that I was the only one who understood it, I just thought that you didn't understand it.  Again, because your post was too vague.

Is there a particular model of movement you can recommend?

If I were needing to do it again, I wouldn't really consider it. With easy WiFi you can do faultless ntp on demand, and if you're even lacking that a cheap GPS module would likely be sufficient. Ain't gonna run for 10 years off an AA, though.

I think so. The complete and utter lack of self-awareness in DrG’s posts here, accusing others (who did nothing wrong) of precisely the things he’s doing… classic projection, perhaps with a bit of gaslighting thrown in for good measure.

EDIT: Also, I really don't want this to be an argument thread or, just as bad, an "I know more than you thread so I am going to correct you". I think I have the operation of this right. If you KNOW you have it right than feel free to explain and all will benefit. But, please, appreciate that I went through the trouble of taking and posting pictures of something that I though was interesting and entertaining.
Posting an interesting original post doesn’t give you the right to be the colossal asshole you’ve been to every single person who replied to you here.

I don't remember what one I bought but I read a review comparing 5 or so different ones. I think I ended up ordering it from https://www.klockit.com/. I have no affiliation with them, just a happy customer.

No need for any ratcheting mechanism, you can remove the whole wheel train and the rotor will still turn always in the same direction. The asymmetry of the electromagnet poles will do the trick. The friction wheel seen in the photos (that with crescents) introduces the necessary friction to allow manual hand setting the mechanism.

Interestingly, such uni-directional motors can be forced to walk backwards applying, instead of a single pulse, two adjacent pulses of different polarities (and the first one being shorter than the other). The first (and reverse) pulse starts the reverse movement, inertia makes the rotor pass the mid-way point, then the 2nd pulse completes the backward movement.

Regards.

If I remember correctly. When the battery, eventually gives up the ghost, but before changing to a fresh AA battery. The clock can go into this funny mode. Whereby it lacks the strength to operate correctly, so the time remains fixed at some point. But the clicking (ticking) and seconds hand, continue, where it flutters, between say, 29 seconds and 30 seconds, then 29, 30, 29, 30 ...
Which I assume, is perhaps related to the mechanism of being able to go backwards, if the pulses were arranged in the way you describe.
It sounds like a fun and cool project, to make a typical mechanical/analogue (battery) clock, run backwards in time. Presumably if you re-arrange the digits on the face, it could read the time correctly, but backwards.

The (typically) black blob IC (chip on board, COB), is also of special interest for me. I sometimes wonder how fast it could be clocked, as it would make a powerful binary counter/divider. If they can be adjusted, to correct for quartz crystal calibration errors at the factory (some people seem to say they can be, but I haven't seen a definitive source, that I remember). Then there must be something more complicated inside, I wonder what ?. Maybe a further binary counter, and (presumably) some kind of mechanism (really cheap in massive bulk quantities), that allows it to retain the calibration setting. Perhaps an array of diodes/zeners  (blown to change the bit, by high voltage pulses, at the factory), like very early PROM devices.
Surely the price point, doesn't allow it to be an OTP MCU, which would be an obvious solution, but a bit too expensive for that kind of application. On the other hand, there are thread(s) here about $0.03 MCUs, so maybe.

In my observation in this thread. If your very first post (or maybe later ones), disagrees at all, with his opinion and/or (apparently) massive list of weird rules and regulations. He immediately adds you to his ignore list, replies to your post, but the post ends with words to the effect, 'I'm ignoring any responses you might make'.

That is NOT the way friendly open/free forums, such as this one works. Especially technical forums.

We had a clock which, when the battery was low, was OK on the 0-30 side but lost time on the 31-60 side, presumably due to a very small imbalance in the second hand.

We do actually have a clock that I had written off as not worth taking more effort over than clicking a 'buy now' link on Amazon - it seems to work but gradually loses time, and not at a trivial rate. Thanks to this thread maybe I'll dig into it and see if it can be saved...

Agreed. The WiFi route makes sense and I have done that, but at least in my case, the controller logs onto my ISP through the router. At some times in the past that was a chronic problem. In fact, I even built and used a circuit to reset the router every night. Later, I had the router on a remote switch to reset it easily from various locations.

True, my current router and ISP are much better and I almost never reset it for any reason at all, but to not have to rely on the ISP at all is a plus.

Of course, that plus becomes a minus when some of the experiences you report occurs.

I was looking again at this product during morning coffee,  https://universal-solder.ca/product/canaduino-60khz-atomic-clock-receiver-module-wwvb-msf-jjy60/ and it still interests me. I was looking at some of the GitHub code for projects folks have used and it looks quite feasible to me (there is even an Arduino project https://github.com/ahooper/WWVBClock and stand-alone projects as well as stand-alone projects https://github.com/bhall66/WWVB-clock).

But, I have no earthly idea how to evaluate how good or bad that antenna might be. It is not even clear to me if the new V3 version improved that aspect  Can you [or anyone I am not ignoring] get a sense for how good it [is] from the specs they give...

Quote
The advantages over other modules from other manufacturers:
– wide operating voltage range 2* to 15V
– 60 mm tuned high-gain, high-Q antenna
– current consumption <100µA (LEDs off)
– super high sensitivity of 0.4V (RMS)
– power down control pin
– fast start-up
– AGC control on/off

Right now I am still waiting for the new clock from Amazon which should come in tonight. If the WWVB works for the clock, I am thinking (rightly or wrongly) that the board would work also.

I mean, it's not like I need another project :) but this is something that I find interesting.

Sorry, it's meaningless to me! And I suspect only meaningful in comparison to something else. For $20 it could be a few evenings worth of fun decoding the signal. And waiting a couple of minutes for a stream to almost complete before detecting corruption.

We had a clock which, when the battery was low, was OK on the 0-30 side but lost time on the 31-60 side, presumably due to a very small imbalance in the second hand.

We do actually have a clock that I had written off as not worth taking more effort over than clicking a 'buy now' link on Amazon - it seems to work but gradually loses time, and not at a trivial rate. Thanks to this thread maybe I'll dig into it and see if it can be saved...

That makes perfect sense to me. I (vaguely) remember reading (or possibly a video) about that, quite a while back. There are reasons why the clock favors, stopping or running in some places rather than others. Unfortunately, I can't remember the details or exactly where I found out about it. It is a mechanical, rather than electronic phenomena. Something which very strong mechanical engineering types can perhaps pick up on.
Since I can't remember it, I'll try guessing. It has to lift the hands up, and do that through the complicated and friction creating gears. So, some positions are wear it tends to rest, when it is almost fully out of having enough power to move the clock hands, correctly.

Also, the radio data (time reference) clocks in the UK, at least my mechanical one. Can sometimes happily show completely the wrong time, or rather the minutes hand is correct, but the hours hand is completely wrong, without warning. This usually/always means it needs new batteries. Presumably, moving the hours hand reliably, needs a bit more power from the batteries, or something. Fascinating devices, anyway.

Regardless, I can help you out by simply not responding to any more of your posts

 :palm:

Are they posting while drunk, too tired, had a really bad day, or something ?


No, posting while insane.  :) "Insanity is doing the same thing over and over again and expecting different results.” - Anon.

Ohhh ok, I gottya, what you are saying is "Movement is accomplished by two magnets. One is a permanent magnet inside the base of that first gear. The other is an electromagnet (i.e., that coil). Energizing the coil creates a repelling magnetic pulse that moves the gear"- thanks so much for the official explanation :)

OK, thanks, I must have been on drugs to think that "Movement is accomplished by two magnets. One is a permanent magnet inside the base of that first gear. The other is an electromagnet (i.e., that coil). Energizing the coil creates a repelling magnetic pulse that moves the gear"

Please explain why "Movement is accomplished by two magnets. One is a permanent magnet inside the base of that first gear. The other is an electromagnet (i.e., that coil). Energizing the coil creates a repelling magnetic pulse that moves the gear" is incorrect. Thanks, I notice that was missing. Third time I am asking in the thread....Beuler...beuler..

EDIT: Also, I really don't want this to be an argument thread or, just as bad, an "I know more than you thread so I am going to correct you". I think I have the operation of this right. If you KNOW you have it right than feel free to explain and all will benefit. But, please, appreciate that I went through the trouble of taking and posting pictures of something that I though was interesting and entertaining.
Posting an interesting original post doesn’t give you the right to be the colossal asshole you’ve been to every single person who replied to you here.

Look, if you insist he stops doing the only thing he appears to know how to do, what is he going to have left?

As he's so fond of attaching psychological labels to people, lets try this one on him for size: https://en.wikipedia.org/wiki/Oppositional_defiant_disorder

/-- mindless howling snipped -/

You were not being ignored by me previously (I promise I will add you to the list momentarily) and here is why; while I remember well your amateur solution to how to change behavior so many months ago, I did not put you on ignore because of your previously reasonable (and sometimes insightful, for a novice) posts on CoVid. I figured, why bother, maybe he has something worthwhile to add even though he knows less about behavior than a kitchen appliance.

I like the ignore list feature. I have never responded to posts or even in a thread of some on the list. They are there because they have posted something so incredibly stupid, that I want to make sure I don't read whatever else they have to say. IOW it, and them, simply do not interest me. Others, like you, get on the ignore list because they are childish fuktards.

I don't have the number of posts that some do, but it is not my first rodeo - I see this fuktard mentality all over the place. I have learned that the type-B fuktard behaves notably different than the type-A fuktard.

If I get into it with a type-B fuktard, they leave me alone and I leave them alone. Neither one of us is particularly special and, believe it or not, I respect that way of behaving. There are lots of people I don't like and I am sure lots of people don't like me - I am ok with that - it is realistic and accepting that is healthy. There are so many people on boards, there is no reason to care a whole lot about that one way or the other.  For the type-A fuktard, however, it is a different matter.

There is an old American expression, "A hit dog will holler" - that describes exactly what you and a few others are doing - you are 'hollering'.

Standing up to them, no matter how long ago, throws off their illusion of balance and self-worth and they remember so well that they just can't get past the experience.

For the Type-A fuktard, to be ignored is the worst thing that can happen to them. They don't get the attention that they so desperately and pathetically crave. They can't leave it alone, they keep coming back for more confrontation - hoping, sadly, that if they can just get into it one more time, there will be a better outcome....and, of course, that never happens.

That you and the few others can't get over your ass-kicking, no matter how long ago, is, indeed evidence of efficacy.

Note that I don't bother with you or anyone on ignore because it is just not that important to me. I know that they are there and I can safely surmise that they are hollering - so what?

Someone ignores me, I am fine with it. If they tell me that I am on their ignore list, I am fine with that and I would add them to mine so I can remember. That is why there are ignore lists.

Note also that every time the type-A fuktard acts out publicly like you are doing now where you have nothing at all to contribute to the thread, go out of your way only to disrupt, sadly try to gang up and bully your way to what you hope will be a different outcome; you put on display exactly what I am talking about.

You might feel better for the moment, but you remain a type-A fuktard and sooner, rather, than later, you will go through the same tantrums - when ever someone calls out your fuktardidness. In the classic sense, you can dish it out, but you can't take it and you can't get over it. That is not my fault and you would do better to direct your anger elsewhere...but you likely will not see it that way.

I don't like you (and the 3-4 other type-A fuktards on my ignore list, so far) and I am never going to like you and I am never going to respect you. Accept that.

I know that this post will piss you, (and those others) off and you (and those others) will holler some more...because, well, because you are type-A fuktards - again, that is not my fault. I have plenty of faults and there are plenty of things that are my fault, but your fuktardidess is simply not in that pot.

So, yes, I will be cleaning type-A fuktard ass bits out of my boots sometimes but the type-A fuktard can't do anything but "holler".

Many us have had to deal with plenty of type-A fuktards in real life. Consequential type-A fuktards, not impotent pissant keyboard warriors. Personally, I never, ever, let them bully me into going away. I will continue posting in this thread and any other that strikes my fancy because I am not breaking the rules and there is no reason why I should go away, no matter how much you wish for that - and, further, the fact is that there is not a damn thing you can do about it, but holler...and now you know that I will never see it.

Life is tough son, wear a helmet and stop hollering.
