This project’s goal is to record underwater sounds with a hydrophone and raspberry pi computer. Please read the attached document “An Autonomous Underwater Recorder Based on a Single Board [login to view URL]” inside the zip file to understand more about what we would like to accomplish. You need to be familiar with Electronics and Signal Analysis. This project consists of two sections. Section 1 Create your own simple hydrophone and record it using Raspberry Pi 1. Create a physical hydrophone based on the attached “Simple Hydrophone [login to view URL]“ document’s design (inside the zip file). If you can locally source the parts, that would be great as it will make the project move faster. If you cannot, we will send you the parts. 2. Connect the newly created hydrophone to an amplifier and sound card and record the sound. The bidder will recommend to us which amplifier and sound card to use. 3. Using the recorded sound, create two graphs: time domain and frequency domain spectrogram using FFT of the recordings. Section 2 Use an off-the-shelf hydrophone and record it using Raspberry Pi 1. Use an off-the-shelf hydrophone ([login to view URL]) and connect it to an amplifier and sound card and record the sound. The bidder will recommend which amplifier and sound card to use. 3. Using the recorded sound, create two graphs: time domain and frequency domain spectrogram using FFT of the recordings.

I'm an experienced developer with a keen interest in the Raspberry Pi. I've worked on many Pi related projects using various input/output boards. Your project sounds very intriguing and I would be very interested in working with you. I've looked at the simple hydrophone design and should be able to source the parts easily here in the UK. I have used conventional microphones to record audio on the Pi and have also generated graphs from ultrasonic distance data so should be able to combine these ideas for your project.
