Based
on the Parallax "Basic Stamp BS2" Microcontroller, all the
components will cost little more than $150 and fit in one hand! A
Hitec HS-805BB Giant Radio Control Model Servo is used to move a
secondary slim rudder and keep the boat on course while you sleep.
The
current heading from the Fluxgate compass is transfered into memory
by pressing the store button. If the boat drifts off course, then the
changed Fluxgate reading will be sent to the BS-2 which will produce
an error signal. This will send an output to the servo motor to turn
the rudder and put the boat back on course!
The
circuit and construction is easy. The programming will be more
difficult for me!
