View Instructable »if you do not need to move the particle up/down, then any focused bowl that can be split in two halves will do the job. For 10mm you can also try the standing-wave levitator which can levitate denser things https://www.instructables.com/id/Acoustic-Levitator/ Best

Easiest way is getting another ARduino that will activate the D2-4, you can also used the simplified version that does not have up-down control. The program used for this one is a not very well adapted version from a phased-array controller https://ieeexplore.ieee.org/document/8094247/Best.

Everything seems in order. Can you try with a small styrofoam sphere (1 or 2mm diameter), you can grab it from white packaging. Could you take a picture of how the levitator deforms the water surface? Best.
