Under normal circumstances I think the water trasnfer pipe will be entirely full of water. No air. Air would only get in if all the water in ten tube on the pendulum were exhausted and air would be sucked in. This would be a fault condition only.
The stepper motor operate at 200 steps per rev...
I don't need to know where the water level is. I merely need to know whether to increase it or decrease it to synchronise the pendulum to the one second accurate pulse.
Similarly the tick and tock is irrelevant too. The clock is already adjusted so they are symmetrical and I see no reason for...
I don't want to do it the way you suggest. My first thought was to use a tiny stepper motor and gear assembly and a 'lead screw' to move a weight up and down the pendulum rod, and actually build an assembly. However it reuired four wires for the stepper motor drive and another four for limit...
Th old clock is already more accurate than I am or need to be. It is not, however, accurate to one second in over a hundred million years and it is simply a fun project to get a 250 year old clock to that level of accuracy.
The fact that I have loop of silicone rubber tubing bridging the...
The idea is to use water to shift the centre of gravity of the pendulum by a small amount. The pendulum rod will have a tube closed at the bottom and open at the top. A second similar tube will be mounted nearby and will act as a reservoir.
The water will be transferred using a peristaltic...
