I can see how that would stop the pendulum from swinging wildly, but for the pot to take readings, it has to be mounted on the pot, right?
The way I'm thinking of designing a pendulum is for it to be less of a circular motion of swinging and more of a linear one. Think of a box with beads in it, when it's tilted the beads fall to one end of the box instead of swinging like a classic pendulum would. Of course, I wouldn't use beads.
