This is great.  I started researching the connectivity of the jack just the other day, with the intention of building an interface to my oscilloscope so that I can see the audio.

I think that is a standard XLR connector.  I will verify that later today when I find my audio cables.  Another approach would be to buy an XLR splitter and run that between the sensor and the box.  That way you don't have to modify the original sensor.  I will be pondering this.

No, it is not XLR.  Similar style, but not the same.

XLR connector

I'm pretty sure all of this has been covered somewhere in the discussion group. The connector is not a XLR even though it looks like it is and who knows maybe it will work it's actually a Chinese connector. Yes I know isn't surprising the connector comes from China. But you get the right connector it works really well.

Now the question is did I keep it in my favorites for eBay and can I find it for you? So yes it's missing from the saved searches it was therefore long time there definitely Chinese as that's where I got mine from they fit perfectly catch is you have to get the right size so I have smaller connectors that don't fit that there is still nice connectors and I'm sure I'll use them someday. But maybe there's another way to find what you need colleges have to do a search

But, what I would really like, is a simple (ideally ready made) interface to connect the Weishi microphone to my PC. I know there's a thread on this, but I'm not knowledgeable on electronics. ( @JohnR725 and @praezis seem to have no limit to their knowledge!)

As far as the audio that should be really simple. Connecting up to the computer can sometimes be tricky because you want to be careful about how everything gets grounded or how everything doesn't get grounded in bad things happen when they do get grounded.

Hi, not sure video links are allowed here, please delete if not appropriate.

Here is a DIY/hack which allows you to hear full watch beat sound from a simple No. 1000 device.

If this was Mark's Facebook discussion group then the link would not be allowed. I can't remember if in the recent rule changes he change that are not because the problem is the person of post the link is profiting from us looking at the YouTube video it be really nice if the person which share a drawing on the group or something. Plus any time someone posts links to YouTube and this is their first and probably only message that's always suspicious. We've had people come to the group of new and telling us about their YouTube channel of the never seen again.

Then found the link to the connector I bought from China it is the exact same connector found on the Chinese machine and it looks like they have some specifications. Just have to specify the number of pins which I believe is three. I know there's other sellers but then they have other sizes so you do have to get the right size

Because the size was bothering me is looking at what I had previously purchased and realize they actually had a image so I snipped out the image.

Is it GX12 or GX16?  Both have been mentioned. Should be easy to measure, the black plastic bit with the 3 holes in it should be Ø9 mm in the GX12 and Ø12.5 mm in the GX16.

Consider looking for extension cables, these give you two connectors with cable already soldered to them and are sometimes cheaper than just one bare connector alone.  One should be able build an adapter with one ⅛" audio cable, one USB cable (for power), and one GX16 cable.

A power + USB converter, for devices without an analog audio input like phones, should be easy to make too.  Not quite as trivial as joining a few cables.  A box with a USB-C socket and a GX16 socket.  One end to the microphone and the other to phone.  Audio ADC needs to be in the box.

Or get an existing high-quality USB ADC, like a Scarlet Solo.  These have a good pre-amp and can supply micrphone power, but it'll be 48V.

GX16

If you look at the link I gave above the ones that I purchased which do fit they say 16. Then I swiped the image off the eBay and it looks like the size is the hole diameter that the thing amounts in which is 16 mm which is what I have.

Then if you're tapping off of the microphone from the timing machine you don't need a power supply. I believe there's a 6 V regulator powering the microphone should have more than enough power to power something else.

    • Might that be the viscous nature of oil resisting gravity H  ,  we have been comparing water and hydrophobic surfaces which are similar in principle but water is much less viscous than oil. I guess what we trying to discover is if epilame also has an adhesive trait as well as being oleophobic. Plus the oil dropet has very little mass for gravity to work on, like watching tiny water beads that can grip onto vertical glass until they are connected together to increase their mass then run down. 
    • But it also makes it seem less susceptible to gravity. If you place a droplet of oil on an epilame-treated surface the droplet of oil will still stay in place even if you then flip the surface from a horizontal to a vertical position. That is, the oil droplet remains anchored, and that's the purpose of epilame. If it was just a matter of creating an oleophobic surface we could probably use other, less expensive, methods!? I don't know @Waggy but my gut feeling tells me you're spot on (pun intended!). I believe the oleophobic property is a side effect of epilame which is designed to keep the oil anchored.
    • Saturday morning 27/4 Sunday evening 28/4 Monday evening 29/4 Floor has a drain in the middle so I am hoping that there is very little fall on it, if any. Room is about 2.5 x 2.5 metres square. Can only use about 1/2 of one wall on the right of the pictures which has a sliding glass door in it. And only about 3/4 of the wall to the left of the pictures as it has the door to the house in it. Progress. 🙂 
    • This makes much more sense now, the oil is withdrawing itself to make as little contact with the epilame as possible. Same principle as wax on a car creates a hyrophobic surface that makes the cohesive properties of water molecules pull together.  The water beads run off only when under the influence of gravity but still remain cohesively beaded up. And as mentioned earlier a pivot would keep the oil in place on a cap jewel.  Epilame on an escapement would be a different scenario, there is nothing to hold the oil in position if gravity tugs at the bead to move, plus the escape teeth pull the oil about Maybe this is why its suggested to run the watch for a short while to remove the epilame to make two oleophobic surfaces either side of the oil, creating a ring of fire 🔥 around it 😅 The oil is repelled by every surface of the epilame even that which it sits upon. So the oil pulls together to make as little contact with it as possible, but the oil cant float above that area, it can only sit there on top of it. Under gravity the oil could potentially run away as an oil bead, unless the epilame has an adhesive property which i dont think it does ? So something else keeps it in position ie a pivot under a cap jewel . But that isn't the case in a pallet jewel situation. 
    • As with every skill it watchmaking, it takes practice. Notice at the top of the document it says, "Practical work - 40 hours".  I can get the balance wheels 'close enough' to flat, but never seem to get them perfect. Same with gear wheels. Guess I need more practice.
