Educational — learn how a geophone sensor is built
Geofón DIY kit is a kit version of Geofón, a sensitive omnidirectional geophone adapted for field recording. Originally designed for seismic measurements, it captures very faint vibrations in various materials and even soil with standard field recording equipment. It sounds best on metallic objects, large structures, trees and ice. The kit uses the same geophone element as the assembled Geofón.
