I wanted to try horizontally spinning brass beads that could collide with the compass spinner, but they would be on a low-friction mount, so they would not drastically interfere with the rotation. I bought brass beads intended for jewelry making and pinned them to a board for soldering. The first used five beads with four orbiting a central, and the second attempt used seven.

I hung the bead clusters from the string and tried to get the compass spinner to tap on it, but the cord imposed excessive friction. I decided to try my usual compass spinner mount with a couple of bolts with divots in the ends poking through coupler nuts. I carved a brass rod with spikes on both ends and soldered two beads to the side. This design had the side-effect of looking phallic. I measured the distance between the spinner and the rotating beads, but when I installed them, they were too far away.

I considered a new design that would let me adjust the height and distance precisely, but I do not like this design, so I will continue thinking of new feedback methods.
