Attached is current schematic of the design.
J6 is the Piezo element, it is rated to run at 1.7Mhz, and should draw about 25 watts at 24v. C23, 27, 28, 29, and 30 are there for flexibility in trying caps, the circuit calls for 3.3nF, which currently is being handled by a single film cap (C98162 on LCSC). L4 and L3 are there to allow flexibility in the 2uH specified inductance, currently I am using a 1uH inductor (C165771 on LCSC) and an adjustable inductor that can go from 0.8uH to 1.6uH. Trying various cap values, adjusting the inductor, trying a few different transistors, I just can't seem to get this piezo to function as it should (It should atomize water and create fog when operating properly.). Also of oddness visible in the second attached image is that there is a weird 50Khz oscillation going on as well.
