The data I presented earlier on this blog, Chasing the Losses, about the energetics of my synchronome were obtained with a simple timer based on arduino uno whose clock is a ceramic oscillator. The qu

Hello there. I am a relatively new member to the group and have been fascinated by all the practical and theoretical science that is being discussed around the running and accuracy of a Synchronome Ma

Good Morning Everyone A less technical enquiry, this, in comparison to most of the chat recently: I am restoring a Synchronome Mk.1 clock. The number on the NRA plate is 1028, which dates it to someth
