Season 10 / Episode 8: Nopeming Sanatorium, The Ultrasonic receiver

The Ultrasonic Receiver is a device that uses an RF mixer and a frequency generator to take in sounds above 28KHz.  Essentially the device is able to bring ultrasonic sounds down to the human audible hearing range.

This was a simple experiment to see what might lie out side the range of our normal senses.

This project was built in approximately 7 hours. Constructed with a 3D printed case and a laser engraved acrylic face plate.
