GPS timestamping works
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.
Ars Electronica 2015
Within the framework of a cooperation between NetIdee and Ars Electronica 2015, I got invited to the Future Innovators Summit. In this program, several people with diverse backgrounds meet to discuss future problems and search for possible solutions.

Relying on solar power supply at the foot of a north face requires proper location planning.
Sonnblick Observatory borehole seismometer
We started the installation of the seismic monitoring network at the Sonnblick Observatory.
Learning by doing
I started with the first small series of GPS Timing Shield PCBs. After resolving some problems it worked fine.
DIY assembly
I started with the assembly of a small series of Ruwai. I chose the Power Supply shield to start because it doesn't contain too many SMD components. Perfect to start learning.
Exciting milestone.
It was the first time, that I connected to a completely self-built Ruwai data recorder.
