    My project right now is the depth finder. I've been looking at fishfinders and how they work and I think that's probably the best way to go -
    run an electronic input into a transducer and send out a fairly low-frequency sound wave since the lake will probably be deep. (Erie/Ontario).
    However, I've been looking for such an ambitious soul who has posted such a schematic but no such luck.
    I'm a little sketchy on how to make a reciever that will take it the returning sound waves. Can anyone lend me their Genius?


    Thank you so much!

    And I also agree that the title of the thread bears no resemblance to the homework topic, if the topic is how to build a depth meter.
    You need to do a LOT of research about how to use acoustical methods to locate the depth of an object in water, i.e., commonly known as active sonar.
    Come back here when you have something to talk about, or you find something you don't understand. We will try to help if we see you are trying to help yourself.

    I really don't think it should be in HW section
    there is zero indication that it homework of any sort

    as a result I will move it and tidy up the thread, removing/editing posts referring to homework
