    HI to every one
    Over the last few months i have been playing about with low frequency for under water RF link to control submarine, a few days ago i decided what about if all of this was joined to a piezo transducer yes it can be done, the transducer in the water if it is held half inch under the surface it starts to make a whirlpool standing out the water about 2inches high and you can see the code on the top of the whirlpool hopefully when i get a bit more time i will take it a bit further and see where it goes if you touch this whirlpool it feels like it starts to burn your finger, i no what you are going to say dont touch it then, but at the moment the unit is running on low power but i will hit it with more power and see if i can start a hot tub for the misses but i don't think she will like the RF burns.

    Very good news but I'm now worried about fish stocks!

    Actually good news of an interesting development.
