Free design seismic data recorder

Ruwai

A free hardware design seismic data logger meeting the needs of scientific data collection and the deployment in rugged conditions.

Ruwai is the spin-off of the Community Environmental Observation Network (CEON) project. Within CEON, the proof-of-concept and a first prototype of the free hardware design seismic data recorder was developed. The data logger is named Ruwai and is now further developed so that it can be used in day-to-day data collection.

The main focus is on full transparency and easy reproducibility. All hardware design files are publish under a creative commons licence and the software source code is published using a GPL license.

First permanent installation › Ruwai set free

Last week we installed two Ruwai data recorders at two field sites. One in a gallery at the foot of mount Hoher Sonnblick and another one at the top of mount Kitzsteinhorn. I’m curious if the data recorders behave as reliable as they did in the lab. Read More ›

GPS timestamping works › Ruwai in sync

One very important feature of a seismograph is the timestamping of the sampled data to an absolute time reference. The most important a global time reference is the GPS time and I'm using it to correctly timestamp the samples of the Ruwai data recorder. A test with another seismic data recorder of a different type shows that it is working. Read More ›

Die GPS Zeitstempel funktionieren. › Ruwai ist synchron

Eine wichtige Eigenschaft eines Seismographen ist eine genaue Zeitmarkierung der digitalisierten mit einer absoluten Zeitreferenz. Das diesbezüglich wichtigste globale Referenzsystem ist die GPS Zeit, die ich für die Zeitmarkierung der Ruwai Daten verwende. Ein Test mit einem geprüften seismischen Datenrekorder eines anderen Herstellers zeigt, das die Zeitsynchronisation funktioniert. Read More ›
