Pictures!

Just like promised a bunch of pictures illustrating our progress with the project.

Here you can see our ultrasonic 

tracievers in our aquarium.

We need to test it in this fashion 

because this transmission setup

only works under water.

Here we have the elektronics for our transmitter system,

on the left of the PCB you can see the transmission circuit.

And on the right you can see the receiver circuit.

Here you can see the osciloscope image, the blue line

is our transmission and the green line is our received

signal.

Just another image displaying the first prototype of the

swimsor casing.
