Caught a nearby building demolition on Sunday morning April 9 around 7:00 AM CDT (12:00 UTC). The building was 13.1 km from my Raspberry Shake (station AM.R0172). Here is the record via Swarm. Here, also, are some nice videos of the implosion:

A rather strong (4.7) EQ in Switzerland, seen by RShakes across Europe: First three stations (from top) are in Switzerland, next ones in Southern Germany, Northern Germany and Poland.
I think already with this simple means you can see a hint of the S and P waves separating in arrival time as they propagate at different speeds.

Here two RShake stations (both in Germany) see this one:

From http://www.emsc-csem.org :
Magnitude mb 4.9
Region FIJI REGION
Date time 2017-03-04 20:03:46.0 UTC
Location 20.52 S ; 178.36 W
Depth 616 km

Predicted phase travel time for my station (top panel below):

Model: iasp91
Distance Depth Phase Travel Ray Param Takeoff Incident Purist Purist
(deg) (km) Name Time (s) p (s/deg) (deg) (deg) Distance Name
---------------------------------------------------------------------------------
147.53 616.0 Pdiff 971.00 4.439 26.37 13.39 147.53 = Pdiff
147.53 616.0 PKIKP 1111.75 1.618 9.32 4.84 147.53 = PKIKP
147.53 616.0 PKP 1115.47 2.690 15.62 8.07 147.53 = PKP
147.53 616.0 PKiKP 1117.54 2.067 11.94 6.19 147.53 = PKiKP
147.53 616.0 PKP 1119.96 4.113 24.31 12.39 147.53 = PKP
147.53 616.0 SKIKS 1482.54 1.382 4.35 2.39 147.53 = SKIKS
147.53 616.0 Sdiff 1797.17 8.323 27.15 14.57 147.53 = Sdiff

So it seems my station saw the 1st PKP phase.

The prediction for the second station :

Model: iasp91
Distance Depth Phase Travel Ray Param Takeoff Incident Purist Purist
(deg) (km) Name Time (s) p (s/deg) (deg) (deg) Distance Name
---------------------------------------------------------------------------------
150.34 616.0 Pdiff 983.50 4.439 26.37 13.39 150.34 = Pdiff
150.34 616.0 PKIKP 1116.19 1.528 8.80 4.57 150.34 = PKIKP
150.34 616.0 PKP 1122.66 2.418 14.00 7.25 150.34 = PKP
150.34 616.0 PKiKP 1123.36 2.069 11.95 6.20 150.34 = PKiKP
150.34 616.0 PKP 1131.71 4.215 24.95 12.70 150.34 = PKP
150.34 616.0 SKIKS 1486.29 1.282 4.03 2.22 150.34 = SKIKS
150.34 616.0 Sdiff 1820.62 8.323 27.15 14.57 150.34 = Sdiff

which also seems consistent. As you can see from the tables, the PKP wave hits the station almost exactly from below, which might help detectability witz a vertical channel only seismograph.

FYI, this site has a list of servers that allows remote station and waveform queries via FDSN webservices, e.g. with SWARM. Not all listed services seem to work or allow public access, but it might be worth checking out to find professional stations near you:

Very distinctive waveforms from the Fiji quake 40 minutes ago.

A 5.4 mag quake in Japan as seen ca 9000km away in Germany. Top panel is my station, middle panel is my favorite reference station , also in Germany, but less noisy backgroud. Note the filters applied. The bottom panel is the unfiltered waveform from the reference station. The arrival times of the big initial spikes are consistent with P-waves from the Japan quake. I think in the middle panel you get a hint of a reflected PP wave even, which would be expected at ca 09:35. Pretty awesome.

Here's a mystery signal I picked up on several days in a row, almost but not exactly at the same time of day. It looks like lots of harmonics of a fundamental in the 2...3 Hz range. From listening to what's going on outside I think this is most likely caused by a train on (relatively) close nearby railroad tracks, which would explain that this seems to follow a schedule or timetable :-). Anybody else seeing things like this?

WinSDR allows to create a helicorder view with a filter applied. Here I used a very drastic 1.0Hz low pass filter to help filtering out the environmental noise. Finally I can reduce the clutter of a helicorder display for a day to just a handful of quake-candidates, in this case it really helped to discover the station had detected a quake near Fiji. It looks like the vertical geophone really helps to see quakes from the other side of the planet as the P-waves will hit the station from below. I'm pretty confident that this is a real detection and not just a coincidence with noise because a professional seismic network also picked up the signal with a consistent arrival time.

Just in, I basically watched this arrive live: a mag 6.4 in Pakistan, seen from Germany with my and a much quieter station (lower panel), also in Germany. The second station doesn't need the low pass filtering, but for my noisier site it's necessary to eliminate the background noise.

P.S.: While learning about the capabilities of the RShake and it's amazing capabilities, it's sometimes easy for forget that for the stronger quakes, we are actually observing real killers. This one, according to early analysis, was within ca 17km of a 30k+ pop. city.... :-( With this in mind, maybe we want to rename the "awesome seismograms" section to perhaps "Interesting seismograms"?
