[PSUBS-MAILIST] Motor Controller Tractor Beam

[Alan via Personal_Submersibles]

Jon,
It's 10k. $20-
https://www.amazon.com/4-axis-Joystick-Potentiometer-JH-D400X-R4-Button/dp/B015IJANPO
It works fine & looks like you could throw it at a wall & it would survive.
It's nowhere near as solid as an industrial joy stick & not sure that it would come
in to the category of semi-industrial.
The pots stick out at the side so don't have any protection against water ingress.
I bought a few joysticks with the thought of making up a small tailor made flight 
control stick which would have a silicone sheath cast around it.
In the photo below, the smallest item is a 2 axis thumb slide joystick, which has
had good comments from the gaming community. I was thinking of mounting
it as a "top hat" joystick is mounted on a flight controller & using it for the vertical
thrusters. The other small PlayStation type joystick seems to have a better range
of movement & feel smoother. The joystick on the left has a third axis that rotates
hence the wide portion.
With my Vesc motor controller, there is a port for plugging in a standard RC
receiver, so very easy to run it off a radio control transmitter. I intend to have
my flight controller wired in but have radio control as well. The RC will be for 
launching & controlling the submarine for boarding from the support boat.

> Alan, currently planning to run wires since it's easiest to implement.  Phase-2 will involve wireless in a similar fashion to what you have pictured.  So you've got that joystick with the button on top, tell me about the quality...it's ok?  What size pots are on it?  Can you take a photo with your hand on it so I can get some perspective to it's overall size?

>> Alan, I like the idea of a larger joystick in most situations.  In my case I'm trying to combine separate thumb-sticks (for vertical/horizontal movement) with a 7-inch graphical display all of which is hand held so I can control the sub whether sitting in the CT or prone looking out the front.

I think my replacements are going to be traditional Minn Kota controllers with a Raspberry PI interface to provide tractor steering.
