@Acturius.
The picture's fine
. I get the general idea. Interesting, i havent seen one of those . Looks pretty functional thou.
But doesnt the float need to have some weight or the helix can block the movement (due to the nature of the movement and friction)? Or even if the rod (endless screw type?) can prevent the float to move if there's enought friction between them ... or a stiff rotating potentiometer connected to the rod?
