40kHz Ultrasonic Receiver Wanted

I'm looking for a breakout board, module, etc that is basically a 40kHz ultrasonic receiver, where if it detect a 40kHz signal it puts a pin high sort of thing (volume level as a PWM whatever, I just need to know when there is a 40kHz signal near by). I was thinking of using a HC-SR04 Ultrasonic Range Finder but they only receive for a very short time after the trigger pin goes high, I need it to constantly be sensing.Ideally works with a Raspberry Pi (ie 3.3 volts output, but 5v just means I add a voltage divider not a biggie)Thanks

Ultrasonic distance measure

Hi eveyone, I'm an assistant cameraman in film and tv and sometimes I've hired in a  professional distance measure device to help with really tricky shots. Trouble is, to buy one costs an arm and a leg, I was just wondering if anyone here had come up with an affordable version. The device sits on top of the camera and sends out ultrasonic pulses to where ever it's pointing and displays the distance in feet and inches on a LED display, that constantly updates. That's all it needs to do. Should have a range of 2' to 15' and be +/- 1" accuracy. Any help would be greatly appreciated.

Make a ultrasonic Dog Barking machine??

I need someone to make a ultrasonic dog barking machine. I have a neighbor who allows their dog to back early in the AM and all during the day, so I want a powerful ultrasonic device that when i turn it on it will make their dog howl at 3AM and wake them up, similar to when the fire engine goes by, so that they will get a taste of what they do to me. This has been going on for a year and I can't get them to do anything to train the dog, they just don't care. I am willing to pay for a device that will work. The dog training devices like you see advertised like "Barkoff" have to be in the same room and all I have read is the ultrasonic dog trainers available don't penetrate walls. I don't want to train the dog not to bark, I want to annoy the neighbors and give them what I have been getting. Evil, maybe, justified, YES! email me direct   myxpykalix@hotmail.com        THANKS

Recording ultrasonic sound

I looked up at bat detector, a device that converts ultrasonic signals into audible sounds. Most bats produce high frequency calls which are often higher than a human ear can pick up. A bat detector picks up the frequencies and then converts the sound into a lower, audible frequency. I was thinking if I could get a bat detector, I use it to capture the ultrasonic sounds.While bat detector could pick up these high frequencies, it would be interesting to see how it will pick up the faintly heard, to human ears - sounds of the industrialised areas/city or even at isolated/quiet areas. The bat detector I want to use is this - http://www.magenta2000.co.uk/acatalog/B ... _Bat4.html I'm thinking of hooking up the bat detector to a digital recorder and a binaural microphone and capture the sound through those equipments. I would greatly appreciate your suggestions/opinions on this matter.

How would I make a sensor sense motion coming at me from behind while I'm moving forward?

I'm trying to make a small sensor that would detect a large object coming at me from behind at about 60mph while I'm moving forward at around 7mph. What kind of sensor would I use? I looked up the different types and I found Passive/active infrared, optic-based, piezoelectric, and ultrasonic. I tried to figure it out myself and my best guess is ultrasonic? Like what cars use to detect deer, they use "ultrasonic airflow sensors". Ideally the sensor would beep and get louder or faster as the object approaches. Would I use an arduino? I'm very new at this :/ Thanks for any help!
