Originally, actually, I kind of built this with a scientific toy I bought online.

It's called, you know, Radio by Light.

And essentially, it's a transmitter.

You hook up to a laser pointer.

It takes an audio signal, like a radio, and then transmits it as light.

At the other end, you have a special receiver that measures the amount of light fluctuation

and translates it back into sound.

And what I realize is that if you actually transmit in basically no sound, but an insect flew past

that laser and interrupted a laser, you would effectively hear the insect.

It's kind of like an optical recording of sound, but if you measure the sound optically,

you can be completely deaf to external noise and only hear the tiny, tiny insects.

A podcast bringing you interviews with tech visionaries.

It's six months moonlighting.

It's nothing on the backcats.

Who share what it takes to change in industry.

I don't exactly know what to do next.

It took many goes to get right.

The company is its people.

The teams help each other achieve.
