Maybe I missed it somewhere in the 5 pages. How will you Represent the water ? Resin, paint, or something like rippled plexi ? 

No you did not miss anything. The water is going to be simple, one colour, and clean (super high gloss enamel paint) - much like they do for architectual design displays.

Designed and testing a servo circuit for the gate servos.

Then I made a circuit board to accommodate four servo controllers, one for each gate.

Made wooden brackets to hold the servos and gate axles under the table.

Made a bracket for mounting microswitches for triggering other electronic circuits when the gates are either opened or closed. Gate lever, attached to gate axle, triggers the microswitch.

Thanks @Gorby for your response.

Though it is the vital part of any working model, not many respond to this part (electronics) of modelling.

Those who may be interested, I am posting what I have been doing to get this model to work.

When the motor is turned OFF the drive shaft drifts to a halt. Under load of the cable system the drift ought to be less. This is important to know so I can adjust the location of the sensors which disable the motors, so the span, and the boat, can drift into their appropriate positions.

Built two motor direction controllers, for span and boat pulley-cable systems.

I’ve “liked” your post above, but have to confess I have no idea what it is.

 

Electronics never were my speciality (along with differential calculus)!

 

Still loving it though.👍👍👍

What Graham just said. Its always fascinating & rewarding if occasionally bewildering to drop in on this thread. :)

My dad was an electrician and would have understood all this gubbins malarkey, but I was the black-sheep of the family. I went into computing. :dunce:

Computing! These days it require a lot of smarts, and constant updating to stay abreast with it all. Good on you for going there.

 

I started with computers when the first DIY computers came out for common folk. The SCAMP computer. All it could do was perform binary LED indications (1977). I was 23, I suppose I was a nerd then. I built a few computers after that, but I soon lost interest after I went into the RAAF _ a different ball game.

My friend, after seeing these figurines, said: "Blimey, there isn't that many people living in Wardell." :D

 

The guy with his hand up, is my first altered figurine. He was the same as the one preceeding it. Since then I have been Dr Franfenstein with these little fellows.
