Hi I used a feeler gauge for the suspension. They are hardened steel. I made pallets from specialist dry bearing plastic. It is loaded with graphite and has similar friction properties to ruby. -- Reg

Synchronome weights & pan
Hi This graph looks right to me. Lets say the weight on the tray was 100kg and the pendulum weight <<100kg. There would be zero effect if the tray weight was at the suspension point. There would be ze

Synchronome weights & pan
Hi I suggest after installing a pan and then getting the clock reasonably close to being accurate. Doesn't matter if it is slightly too slow/fast, so long as you know what the error is over 24hours. T

auction, 6 Synchronome clocks
Hi The prices high and the bids are zero. The difference between asking price and market value. I think it is good to post ads like this on this type of forum. There is no way I would have found these

ESP32 Wifi Clock Driver
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, configuring Wifi exception/error handling

ESP32 Wifi Clock Driver
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. Regards Darren Conway Lower Hut

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 connection. This includes full

Hi I am thinking of replacing the wires between the master and the slaves with Wifi. This will also mean that the slaves can optionally be pulsed from ultra accurate atomic clocks connected to the Int

Accurate Time Service Slave Clock ??
Hi Here is a slave I haven't seen before. Just wondering if it would be compatible with a Synchronome master clock. Regards Darren Conway Lower Hutt New Zealand Virus-free. www.avast.com

Synchronome 96A slave GPO advice
Hi That is far too simple and clever. For hobby stuff, I work on the principle of "why make it simple when you can have the challenge of making it really complicated, and get it to work" 😉 Regards Dar

Synchronome 96A slave GPO advice
Hi I am an Electronics Engineer and I am currently designing and making a pulse generator for two types of slave clock, including Synchronome. I am using cheap ready made Chinese electronics modules.
