When most of us think of seismographs, images of broken buildings, winding roads, and search and rescue teams digging in the rubble come to our minds.But when [Subir Bhaduri] As part of the 2020 frugal science course, his team faced the challenge of solving real-world problems as frugally as possible. He thought of farmers in rural India who lost their crops by attacking elephants. Such attacks may and have caused the loss of human and elephant lives. How can he use scientific methods to prevent such conflicts at low cost?
Whether the inspiration comes from using a computer mouse whose mouse speed becomes “orbital speed” is controversial, but [Subir] Trying to find out whether this sensitivity can be used to detect earthquakes on the elephants mentioned above.His proof of concept is a Very frugal, low-cost seismograph using an optical mouse and some cheap PVC pipes and fittings.
We invite you to watch the video below the break to learn how it works.You will be as impressed as we are [Subir]The practical application of engineering principles. And open your eyes to admire the beautiful magnetic damper hacker. This is a real treat!
If exaggerating the annoying pachyderm p-waves arouses your interest, perhaps you will appreciate previous projects that used piezoelectric pickups and pipe parts to generate data.
