The Batometer

When Mike and I went to Austin, we could hear the bats in the bridge making mouse noises contentedly, but we couldn’t hear the ultrasonic noises they made to fly. This homemade device can make those noises audible to you.

Mike and I need to make this before we go to Austin next time so that we can enjoy both facets of the bats.
