Thank you again for all the replies. Peter, I would like to keep the clock as original as possible! The current wire is 0.028" dia with 14 strands 0.005"dia and it's coloured green. It is not very

Hi Ian, I bet your version was neater than mine then which was all Maplin bits and pieces and looked very unsightly. I have now remembered that for moving the dials forward in the spring, I

Thank you John. I hadn't realised what a wealth of information resides in the file section. I will enjoy trying to get my head round the circuit logic for the distribution board in your

Hello Phil, The flat spiral springs can be obtained from here:-- https://www.cousinsuk.com/product/hairsprings-clock I have various types of cable available here from antique types

Try The Scientific Wire Company Regards Peter

Thank you both for the prompt replies. The existing wire is no longer safe having lost most of its covering. My searches for the appropriate wire has come to nothing so far so any help in that

Hi Brian, I did exactly what you described by providing a simple two-way switch to divert the external clock circuit to a rheostat which was adjusted to maintain the required current through the

Hi ....I believe both spring and wire are correct and original depending on age and any service replacements of course.....so probably worth keeping as is. This was one of the few changes GJ made in

Hi Phil, I used to have a G&J clock, but sold it a while ago. It did have the flat spiral spring as you described, and these are obtainable from clock suppliers as phosphor bronze balance wheel

Yes. The pilot dial is connected in loop 1 (called the home loop) and controlled in the same way as the other loops. It is done in quite an unusual way. There is an explanation of how it works on

Ah, I see. And does the pilot dial on the clock also stop for an hour as well or does that stay at GMT through the year?

The Synchronome distribution board does exactly that. I put back my system yesterday (about 30 dials in 6 circuits via a 6 channel distribution board. I switched all 6 dial circuits to

Hello, After this morning's adjustment of the synchronome for GMT (which i did with the traditional method of stopping the pendulum and waiting an hour), I wondered out of curiosity if anyone had

Hello, Can anyone help me please? I am working on my G & J master clock after 5 years in storage ( the clock not me!). Apart from a rusted solid screw, which had to be drilled out, the wiring to the

Hi The answer from me is: no, not yet. The code for conveying ticks is the easy part. Most of the code will be for things like: day light saving adjustments,

All these are hardware - please could anyone post links to code for conveying "ticks"?

Hi I didn't know about Lilygo. It is definitely a very capable and adaptable item, but the price and capability are more than I am looking for. A basic ESP32 is enough.

Try the Lilygo. It is very powerful. Neil Jepsen. B.Sc. M.Sc(Hons).CPL.MASNZ.Jepsen Acoustics & Electronics Ltd22 Domain StreetPalmerston North.New Zealand.Ph +64 6 3577539 Mob 0274428094Web

Hi I have used XBees extensively but they are a lot more expensive than a E32 microcontroler. I am looking at using an ESP32-S2 version with an internal/external antenna

I have used a device called an XBee for this sort of thing. If you set two of them up properly they are a transparent link where you feed pulses into the sender and they come out the other end from
