First sounds from my Piezo Hydrophone
Not having ever used a hydrophone (underwater microphone) before, I thought it would be fun to try to build one aboard the Swan and hear what the Shetland coastline sounded like. This ‘Piezo Hydrophone’ is built using a simple piezo pickup soldered to a guitar lead and dipped in plastic paint.
My first test was carried out in the Scalloway harbour. I was happy to hear it worked!.
The harbour predominantly resonates with the sounds of engines, fridges and other manmade motors and bleeps. As we venture out of the harbour it will be interesting to discover what other sounds reveal themselves.
This ‘Piezo Hydrophone’ was built using a recipe from ‘Hardware Hacking’ by Nicolas Collins (rev. 2.1, May 2004).
