hydraulic pump - convertible top- replacement for linear actuator
#21

I am using a 10Amp H bnridge PWM controller for it.  I had to do a few mods to the Arduino code to drive this.  The pump drives a double acting ram that is directly linked to my transom hung rudder.  I have a bypass valve across the ram to allow normal tiller steering.  This has a switch to detect when it is open that is connected to the Pi and disengages Pypiloy automatically.  I also fitted a linear pot in parralel with the ram to give rudder position feedback to the Arduino.
