The Grove DIY – An overgrown pub carpark transformed during lockdown
The Viennese high fog has settled, so uniform light is guaranteed. I took this opportunity to take photos from St.Marx DIY, which has grown quite a lot this year. Just started the structure from motion workflow. Let's see if I have captured all important details, or if I have to revisit the site to fill in some gaps.
Reminder: Springer has released a lot of digital textbooks for free in the last few months, and their special offer is ending on July 31st. There is no need to sign up to download the PDF and ePub files.
This lovely page has the full list of available titles: https://hnarayanan.github.io/springer-books/
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.

Everyone is streaming...I'm in. I have created m-aar Radio at https://www.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.....
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 #Zagreb 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.

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.
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.
And this one is growing.
