Only $30 for an SMT prototype order. Free shipping & free stencil.
A Geophone is a device used to detect and measure ground movement or seismic vibrations. This time I will describe to you how to make such a sensor yourself for free from parts that can be found in any workshop. However, the sensitivity does not lag behind commercial geophones at all. Even this sensor reacts to shocks in all possible directions which makes it incredibly practical, In other words, it replaces many different types of Geophones.
This sensor is conceived as part of the final project, which will actually be a stand-alone seismometer and will display the relative intensity of the earthquake at the point of detection. In the next video that I will promote soon, will be described the electronic part consisting of an amplifier, filter, A/D converter and PC software. Thus we will get a complete extremely cheap and sensitive home seismometer.

Great project and wonderful presentation. I suggest you to twist connection wire between winding to signal conditioner board to minimize interferences.

dr mirko, i built your seismometer and sensor and it is amazing. thank you very much for your fine work!

Ancient armies (I forget which) would dig holes and listen for the footsteps of their enemies. I forget the exact method, but it was effective and interesting.

09:10 Damping! I had no idea Thank you It reminds me of the Kibble Balance - here is a cut and paste from the wiki about the design: The Kibble balance is a more accurate version of the ampere balance, an early current measuring instrument in which the force between two current-carrying coils of wire is measured and then used to calculate the magnitude of the current. The Kibble balance operates in the opposite sense; the current in the coils set very precisely by the Planck constant, and the force between the coils is used to measure the weight of a test kilogram mass. Then the mass is calculated from the weight by accurately measuring the local Earth's gravity (the net acceleration combining gravitational and centrifugal effects) with a gravimeter. Thus the mass of the object is defined in terms of a current and a voltage- allowing the device to "measure mass without recourse to the IPK (International Prototype Kilogram) or any physical object" (Wikipedia)

Hi Mr. Mirko I'm a geologist but also electronic enthusiast so I'm very interested in this project. I have a question: does the dumping with aluminum plate reduce sensitivity ?

Hi! All of your videos is really impressive, interesting and powerful, thank you to share your knowledge! We are working on the health sector. What do you think, how is possible to read biology informations from the organs and share or store as a wave as a spectrum? We are working on Peter P. Garyaev solutions, but has any other easyer option? If has, please create a simple video when you have time and energy for that. Thank you! Roland

KZfaqr Clickspring happened to show exactly how to make that spring at about the 17:48 point of this video kzfaq.info/get/bejne/n9RmrLqj0c_LmH0.html Watchmaking - Making Carbon Steel Hairsprings for Watches, Clocks and Other Small Mechanism. He makes a ball former with grooves for the wire (with incredible patience) and then heat treats and tempers it

Hey, I m looking to create cheap earthquake detector kit for earthquake affected areas (to help people cope with stress). I recently tried to build your other detector and really like its design. I was wondering, is this design better? How does it compare to old one? Is there something even better out there perhaps?

This is the best and also the simplest sensor. In the next video the electronic part of the device
