What's so complicated? Seems to me you need a longer arm and a gripper that is always fixed to the radius of the point where the string goes to the racket is say 1/10th the radius of the arm at any angle. If you have a 6 pound weight (weight and bar) then you have 60 lbs. Automatic drop weight pure and simple.

But what you have is a fixed distance on the rotating device at the gripper. The effect length of the weight continuously changing above and below the bar so you leverage changes. I am not an engineer but that's not hard to figure out.

EDIT: BTW the reason for the longer bar is so you have more travel and you don't have to regrip the string.
Everyone has the right to be stupid... it's just that some people abuse the privilege
