Elements H2O not change gas state

hi,
The Ultrasonic nebulizer is used to atomise water into a spray, similar to an aerosol spray.
It will not split water H2O into H and O

How is the output of the oscillator/amp 'connected' to the water.?

Hi trankhanhcr,
The circuit in the video (Post #20) is different to your schematic in post #17. The circuit in the video does not have the inductor in the feed to the emittor so it can not possibly work. It does have the wiper on the potentiometer connected to one end of it's track. Maybe it sould be connected this way in your schematic.

Les.

All Parts must be exact same, * unless you understand the differences
