Locating the source of a mysterious beep

MKBHD demos the the FOTRIC TD2e Acoustic Imaging Camera.

It costs ~$1,000 so you'd probably rent it if you're only going to use it once, but it's a neat gadget.

WHAT WAS MAKING THE BEEP!!?!?!

You can also solve this in O(logn) using a physical binary search:

1) Move half the boxes to another room.

2) Listen for a beep and determine which room the beep comes from.

3) Take the boxes in that room and split it in half again.

4) Repeat until one box is left.

wonderful! Thanks for sharing. I thought about doing this to track the sounds moving around in my stomach... it is interesting how well the mic on your smartphone works at picking up stomach sounds

Woah this is cool. Another interesting simonw project based around sound through browsers. Lots of simple real world problems that can be tackled with this.

Who would win?? :-)

I lack the courage to plant such a PCB prank device... it really feels like you could drive people completely crazy haha

You know what might have been easier... Going through the boxes!

Could you build this into a HUD for a cat, tuned to mouse squeeks? Asking for a friend.
