The most eye catching feature of his clock was a pair of dumbbell balances gently rocking to and fro in synchrony. By being interlinked the aim was to negate the effects of a rolling ship.
My version has two interlinked compound pendulums which have a two second period but are gravity controlled rather than spring controlled as in the original. It also employs a grasshopper escapement which is frictionless and is ideally suited to wooden clocks.
The clock is weight driven and the weight is rewound by a small electric motor every two minutes or so. This is modelled after a Wagner remontoire. The electric motor itself is the driving weight.
The motor is derived from a modified radio controlled servo acting as a straight motor rather than a servo. The action of the rewinder can be seen in the video below.
Because it is modelled on a sea clock I thought it appropriate to send it to sea. Perhaps not literally but by mounting it on a tilting table which is operated by a small stepper motor. Both the stepper motor and the rewind motor are controlled by a small microprocessor. The microprocessor is powered by a 5 volt mains adaptor.
Below is a short video showing the clock in action
