Another Winter Project Complete (I hope)

[Cane Pole]

You may recall that I added joystick steering to my pondtoon last summer. The joystick is a commercial version with a stiff return spring. This stiff spring created a problem of overshooting the start point of the pwm circuit that drives the steering ram. This overshoot caused the boat to respond to quickly which caused over steering. I got used to the steering, but others had problems with the over steer, especially the first time drivers.

To compensate for the overshoot, I modified the pwm start position from 10* to 20*. This works perfect, but doing this modification, caused the pwm rate to lag. I fixed this by adding a miniature switch in the handle of the shifter that engages when the button on the shift knob is depressed. Ah! Turbo boost steering.

The new shift knob is a generic Volvo shift handle with the reverse button in the center that I purchased from Ebay. If I push the button, the pwm rate shifts by 25-30 percent, which compensates for the lost shift from the detente position being moved.

I like the look of the new stick. Does it now have that sports boat feel?

You got too much time on your hands Cane Pole. I think that Northern Winter this year has run way too long!

German engineering? Glad you happy. No matter how you steer, that is still one cool fishing boat.
