Migrated my Jekyll site to the Foundation 6 Framework using the new XY-Grid. No problems, it was a pleasure. Integrated a Vue/Vuex app using leaflet also worked fine.

Visit mertl-research.at/mss-nrt-map/ for live visualization of the seismicity in the Vienna Basin.

Everyone is streaming...I'm in. I have created m-aar Radio at mertl-research.at/maar_radio/ which currently streams the sonification of seismic data recorded on a Greenland glacier. 184 days from May to October 2012 resulting in 21 hours and 28 minutes of streaming audio. Tune in and drift into the great white nothing.....

It's great to have control over the output in 5 ns increments. Beaglebone Black PRU and assembly is fun.

Output pulse with 105 ns and 110 ns length triggered by a GPS PPS signal (yellow line).

Working on a GPS disciplined clock signal for using BeagleBone Black PRUs in my home-office. I'm currently testing the timing performance. The fastest time to set an output GPIO high in response to an input GPS PPS signal is ca. 35 ns using Assembly code.
I didn't code in Assembly for ages, but working directly with all the hardware registers and knowing what every clock cycle does is somehow beautiful.

The earthquake today at 05:24 UTC with an epicenter near and a magnitude of ML = 5.4 (ZAMG) has been detected by the MSS network in the Vienna Basin and marked as an event which might have been felt in a wide area.
The aftershock at 06:01 UTC with a magnitude ML = 4.9 (ZAMG) has been detected as well.

Visit mertl-research.at/mss-nrt-map/ to get near real-time information about the seismicity in the southern Vienna Basin.

Working on building two of my open hardware design seismic dataloggers for a short-term deployment in Greenland. Besides building it, I also have to include some hard- and software improvements. Let's see if it works out...
So far, thanks to KiCad 5, the redesign of a power supply PCB has been a joy.

My book recommendation for these days: "The Masque of the Red Death" by Edgar Allen Poe.

If you ar looking for a contact microphone based on a seismic sensor, check the Geofon by LOM. It's great to pick up low amplitude vibration in solid bodies.


Found a great tool for my lectures. An interactive whiteboard: openboard.ch. Go and give it a try.

My search on hashtags like or leads to manageable results. Aren't there any seismologists out there?

I'm currently developing a near-realtime display of seismic data recorded with our MacroSeismicSensor network. For testing I needed a software to feed archived seismic data into a near-realtime data flow. I've found this great tool which saved me a lot of time: github.com/rannof/srtpb.

I've used the last warm autumn day yesterday to go out skateboarding and collecting some photos for my Skateboard Architecture series.

Take a look at the whole series:

River mouth with housing and factory building.
