Chirp Buster

Crickets announce their location with each sound they make

Dave Wheeler sat at his drafting table with a half-finished circuit schematic glowing on the monitor. The numbers refused to add up. Every time he reached for the next calculation, a sharp chirp sliced through the office air, followed by two more in quick succession. The crickets had moved in three weeks earlier and treated the space like their personal concert hall.

He tried headphones. He tried a fan. He even tried working from the break room. Nothing worked. The chirps found him anyway, high and rhythmic, perfectly timed to wreck his concentration. Dave pushed his chair back and stared at the ceiling tiles.

“Fine,” he said to the empty room. “You want to sing? I can use that.”

He cleared the desk and started sketching. First came the locator. Two small microphones mounted on a lightweight frame, tuned to the exact frequency range of the house cricket’s song. A simple processor would compare the arrival time of each chirp and point the craft toward the source. He added a quiet electric motor and four tiny rotors so the whole unit could hover and turn without slamming into the filing cabinets.

The capture part took longer. He did not want to crush them. After two evenings of testing, he settled on a short, soft-sided collection tube that dropped over the insect the moment the drone was directly above it. A gentle puff of air guided the cricket inside. The tube sealed itself, and the drone flew back to a charging dock on the windowsill.

The holding system sat in the corner of the office, a clear plastic enclosure with mesh sides, a water sponge, and a little bit of cardboard for cover. The temperature stayed steady. The crickets lived comfortably until Saturday morning, when Dave transferred a few into a bait box and headed to the lake.

By the following Thursday, the office was quieter. The remaining crickets still chirped now and then, but Dave barely noticed. He had a working prototype, a growing supply of live bait, and a schematic that finally balanced. He saved the file, leaned back, and listened for a moment. One last chirp sounded from behind the bookshelf. Dave smiled, powered up the drone, and let it go to work.
