Do It Yourself

!!!Shakers!!! This is your space! Our 'Do It Yourself' section aims to share some resources that will be useful as you build things on your own. Enjoy and have fun!


IDEAS: Why not customize the design of your enclosure, or personalize it with your name?


Pinout Diagram for 1D

Computer: Raspberry Shake 1D can work with several Raspberry Pi models including the Model B, Model B+, 2 Model B, 3 Model B, Zero and Zero W, but we recommend using the Raspberry Pi 3 Model B. The Raspberry Shake 3D and 4D will work with Model B+, 2 Model B, 3 Model B.

Geophone Sensor
Geophone RGI 20DX

For the 1D and 4D models, we recommend using a RGI-20DX 4.5 Hz, 395 Ohm, Vertical Racotech Geophysical Instruments geophone.

Here are the specs: Racotech Geophone Technical Specifications.

For the 3D model, we recommend using Sunfull PS-4.5B vertical and horizontal geophones.

Here are the specs: SunFull Geophone Technical Specificatons.

For the moment, if you are thinking of forwarding your data to the Raspberry Shake Community in real-time, these are the only geophones this is the only geophone that will be accepted for use in the automated earthquake detection process. This is because we know the instrument response of the Raspberry Shake board with these geophones. The Raspberry Shake Community server will treat other geophones as unknowns with unknown instrument responses. (The instrument response is used server-side to determine the magnitude of earthquakes. It allows us to correct the signals to true earth motion and compare seismograms recorded by different makes and models).

Geophone Polarity for all models: If you are using a RACOTECH geophone from OSOP and you connect the grey cable from the “+” on the geophone to the “+” on the Raspberry Shake board, the output signal will have the correct polarity.

If you wish to use geophones from other manufacturers, the geophone should be a 4.5 Hz geophone in the range of 380 to 400 Ohms. 1 Hz and non 380-400 Ohm geophones will not work with Raspberry Shake's analog front end.

Caution!: The geophone input is ESD sensitive, and ESD precautions must be taken when hooking up the geophone.


Raspberry Shake SD Card

For those of you who are interested in programming your own routines to visualize and process the data, we recommend using the ObSpy Python library. This is a really cool tool for exploring your Shake and doing amazing things with the data. See also: FDSN Web Services.

The same SD card image will work for all Raspberry Shake models: 1D, 3D and 4D.

IDEAS: Why not try your skills at interpreting the data from your shake, to notify you of any peaks, and even identify similar patterns that happen throughout the day, to better understand what you are seeing!
