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

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

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

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

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

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

Hi I am looking at the problem of connecting my master clock to my slave clocks at the other end of the house. I also have a Solari slave flip clock that requires a bi-polar 48V pulse every 60 seconds

Hi If materials like Delrin were available when the clock was made, it may have been chosen. When I purchased my clock it was missing the ruby on the gathering arm. Impossible to obtain here. I made o

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

Hi A resistor was used to suppress sparks across the contacts as they opened. Sparks erode the contacts. If they had diodes available then, they would have used them. That is what you should use inste

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

Hi I am using an Arduino Uno for my design. I don't think the radioclockcontrol units are over priced given the tiny market, their performance (Quartz/GPS time keeping) and features, but more than I w

Hi I was right. My design is far from unique. These look like good modules and available off-the-shelf. No electronics skills required. Regards Darren Conway New Zealand Virus-free. www.avast.com

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.

Hi I inserted a small piece of shoe inner sole to absorb the shock and reduce the bounce. The piece was inserted as shown in red on the attached image (OPs clock). The silicone gel type soft material

Hi Neil Do you have a Trademe auction number? I am currently looking down the DIY lab frequency standard rabbit hole and it is looking a lot deeper than $40. It looks like many of the Aliexpress U-Blo

Hi I have been looking at using a GPS receiver to use as reference time for a RF signal generator upgrade. I have also been working on developing a arduino based controller that will drive both a Sola

Hi Another solution would be to connect a U-Blox NEO GPS module to a slave. These can be configured and interfaced to provide a super accurate 30s time pulse. Regards Darren Conway New Zealand This em
