I know there are more elegant solutions, but I like to make it cheap and simple. I have a boat with mechanical steering, that I'd like to be power assisted steering.
The tiller on the rudder has a hydraulic actuator (currently only used by autopilot) that is driven by a hydraulic pump. They hydraulic pump is driven by a DC motor that can be reversed by switching polarity.
My idea was to mount a small DC generator to the steering wheel, that will generate enough current to actuate a relay. In other words, when I turn the steering wheel the DC motor for the hydraulic pump should start in one direction and switch direction when I turn the wheel the other way. It also has to stop when I stop turning the wheel. I need to add that when the hydraulic actuator pushes the tiller, the steering wheel turns as well.
Could this work and if so what hardware and relays could I use?
