Catch the ultrasonic frequencies of Bats with Batometer

Batometer is the new creation of Tony Messina that equips you to listen to the ultrasonic frequencies that bats make when they use echolocation to fly in the dark.

Equipped with combination cell phone, camera, electric shaver, gps logger, and calendar with the added feature of bat detection, the batometer could also be used to perceive high-pitched mermaid sounds as well.

To quote Tony Messina,

'On retirement, I decided to undertake the design of an ultra-portable, personal bat detector. It is small in size, lightweight, easy to build, and can cost as little as $25 in parts. It turned out to be an amazingly simple yet effective circuit so I dubbed it the Simple Bat Detector.'
