In that case, I really do recommend the Troy exhibition. The last time I was so touched by an exhibition in the British Museum, it was Tutankhamen and I was about seven.

I confess I still don’t quite get that, but are you sure a frequency divider and a binary counter are the same thing in anything other than base two? Mind you, if you are correct, and I’m sure you...
I agree that the ones you have posted here are not Smiths but I’m still not absolutely convinced the other way. However, you’ve made a strong case and I’ll do a bit more research. Thanks for the...
I'm not sure that any of the other cases have an identical caseback to the Smiths diver . The examples you gave certainly didn't. Likewise, I haven't seen any others using the same font on the...
That was my point - the Ronda was the first cheap and cheerful quartz and is still perfectly capable. That fact may be obvious today, but it wasn't in '73. The Ronda demonstrated this at a point at...
The £35 quid one I was going to have a shot at. Fortunately, I picked up this hen's tooth while searching for variations earlier:

For what it's worth, a trip to the British Museum confirmed my scheme for the Omega, although their records don't mention a final division from 3 to 1, which is odd and probably a mistake as the...
And just for the fun of it: the Omega 2.4:
2,359,296 /3
786,432 /2
393,216/2
196608/2
98304/2
49152/2
24576/2
12288/2
Ok, I think I can tell a consistent tale from start to finish. I'm not promising that it is correct in all the details, but it fits what we know so far.
I like poetry. One of the reasons I like...
This has happened to me so many times that I now don't even bother. I've found that using a little bit of blutac to hold anything small enough to ping is perfect for orienting and setting up before...
First, tokdoc, cheers, pm sent...
Second. As I'm finally not seeing spots in front of my pain for the first time in days, I celebrated by doing maths. I'm not good at maths, but I think I've...
I'd like to see a you tube vid from the side with the back open too so we can slow it down and see precisely how the stepper motor moves, because I'm struggling to reconcile a .5 hz pulse with a one...
Indeed, but with two discrete stators, and four rotor magnets, that offers a far greater range of possibilities than the standard dipole stepper motor. However, as you know, magnetic effects drop...
Here’s a few of my Omega ticking from 1hz to 720hz

Here’s a couple more:

Well that's one hypothesis sunk then - mind you. given the nature of the system, whatever it was would take one second to start as that's how long it would take to work through the IC...
That...
Nope, I just can’t tell the difference between ‘gilding’ and ‘gliding’. I was thinking of the movement of the second hand. Does it tick once a second or move in a slightly smoother manner?
Gliding?
When it comes to the actual electronics, I'm pushing myself, there's a resistor (and it isn't variable - I'm sure someone can tell me the resistance on sight, rather than needing to dig the code...
Just a few ideas before I head to bed - that's definitely a stepper motor then, but what a stepper motor! The IC is clearly a cmos and not something earlier and looks suspiciously similar to an...
That’s going to be really interesting. Thank you.
Well, I’ll be damned! You are quite right. I was told that by someone I considered an authority about thirty years ago and have been repeating it ever since. Thanks for correcting me. This must be...
There are a variety of different shapes or cuts of quartz. The two most common are precisely the shape of a tuning fork, which is precisely what it is, holding a precise “musical’ note due to its...
In the same way as Crick and Watson discovered the structure of DNA. As Marie put it some time later:
”It is easy to overlook those who have not the active support of influential persons”.
An electronic overflow integrated circuit isn't hard to visualise, just think water:
Imagine a tap running water into a pair of cups.
Every time both of the cups (2 in total) are full, they...
Ooh, that's lovely.
I don't think that we are in any danger of misunderstanding each other and as you were explaining something I didn't fully grasp, it's churlish to labour the point, so I'll...
