We want to create a machine that can trace birds and bats to know were they are going, what kind of spieces fly over,in which direction they fly. This is all to know more about the spieces to know were they are flying and to investigate there flight pattern.
There are many varients that people can make. First of all the system has to be cheap because how more machines we got how more precise we can say where the birds and bats are flying. It must be very easy to install so every people can buy one and install it there one.
Being cheap is our mane objective. Therefore we found some cheap mics. Of cource we have to test them before we can decide which one we are going to use.
See here the 2 mics:
I know the second is much more cheaper but we have to test if it is okay.
To concentrate the sound waves we would use a parbolic reflector but we have to think about a cheap and easy way to make one.
