First Homemade PVC Geophone for Earthquakes
Through this project I try to bring to earthquake study lovers a geophone seismometer very easy to make and also very cheap. The amplifier I use in this project is the same one that I presented here at Hackster.io ( https://www.hackster.io/washington/super-cheap-amplifier-for-earthquake-sensors-388fd1 ) where I set the two potentiometers for one final gain of 2500X. According to the geophone performance this gain can be modified in the amplifier for more or for less. The sequence of photos and videos below speak more than my words.
