Re: DIY Hydrophone

As an update, I thought I'd share my first recording using the DIY hydropho=
ne - molluscs feeding in a rockpool.



I ran the recording through Sonic Visualizer and recorded a screen grab to =
give the following video:

Quite pleased with how the recording came out. Although one modification I'=
ll need to do is to add some ballast to the hydrophone, as it was floating =
to the surface of the water, so I had to physically hold it under the water=
.  Not so bad in the Summer, but that'll be rather cold on the hands in win=
ter!

Brian.
