Phidget Spatial 1056 USB Accelerometer Support
I have added support for the Phidget 1056 USB accelerometer for Windows and Mac with QCN. You need to install their Mac kernel driver for Mac OS X, but no driver is required for Windows. I hope to have support for Linux soon. http://www.phidgets.com/products.php?product_id=1056 16 Apr 2012 | 19:55:45 UTC · Comment

HP Laptops Supported (With HP 3D Hard Drive Protection)
Thanks to Rafał Ostanek of Poland, I have managed to have QCN connect to HP laptops. It's still an "experimental beta test" - but if you use BOINC on your HP laptop (that has the HP 3D Hard Drive protection software installed and active), your HP laptop accelerometer should be able to be monitored by QCN. The sample rate is very low, so it will look different than other sensors (more "square wave") - but it does seem to detect triggers i.e. changes in acceleration etc.

You have to get the version appropriate for your operating system, i.e. 64-bit Windows you should connect with a 64-bit BOINC client etc. And of course you need the HP hard drive protection software installed and enabled. There is no 64-bit Windows QCNLive, but if you have a 32-bit Windows on your HP laptop, you can try QCNLive (i.e. "offline" test):

ONavi USB Sensors Work Under Linux
The ONavi USB sensors (both the 12-bit and 16-bit) are now fully working under Linux with both QCNLive and QCN under BOINC. No drivers are needed to install. As the ONavi sensor shows up as a "pseudo-modem" (/dev/ttyACM0) you may need to check the permissions to ensure that your account has read/write permissions to this device. For example, you may have to add your account or the BOINC account to the "dialout" group so it has permissions to use the ONavi sensor. The other QCN USB sensors (JoyWarrior and MotionNode) already have Linux support. 1 Apr 2012 | 3:56:10 UTC · Comment

Angela Chung Receives 2012 Stanford-USGS Fellowship
Please join us in celebrating Angela Chung’s great news. She will be the 2012-2013 Stanford-USGS fellow. Angela is a 4th year PhD student in Geophysics at Stanford working on many aspects of QCN. During the 2012-2013 academic year, Angela will continue to work on all things QCN, including testing low-cost MEMS sensors with John Evans (USGS). Way to go Angela! 15 Mar 2012 | 0:35:56 UTC · Comment

QCN Detects Earthquake In Seconds
On Tuesday at 5:33AM, QCN detected a magnitude 4 earthquake near Berkeley, California within seconds of the earthquake origin. The event was detected 5-7 seconds before the strong shear waves reached Stanford University, where the QCN servers are located. 15 Mar 2012 | 0:34:11 UTC · Comment

QCN Upload/Download Server work
I am moving a lot of data around so the download servers may be offline for a day (this shouldn't affect uploads from BOINC clients). 15 Mar 2012 | 0:26:10 UTC · Comment

Earthquake in Christchurch, New Zealand
Watch this video and see a M5.2 earthquake send seismic waves across Christchurch, New Zealand on October 4, 2010. The circles show the location of seismic stations that recorded the event, including 118 QCN sensors and 29 GeoNet stations. The colors denote the intensity of the ground shaking, measured here as acceleration, with grey indicating no shaking and bright red indicating the most intense shaking during the event. The maximum acceleration measured on the stations was about 1 m/s/s, or approximately 10% of the force of gravity.

The trace at the bottom is a type of a seismogram that shows the energy released versus time. The first small increase in energy is when the P-wave arrives at the station and the large jump in energy occurs when the larger amplitude S-wave arrives. You can see that there is continued shaking across Christchurch for 20-30 seconds, this late seismic energy is known as coda. It is due to the reverberations of the waves in the relatively loose soil that Christchurch is built on.

This earthquake was one of many aftershocks recorded by both the permanent New Zealand network, GeoNet, and temporary QCN sensors. Approximately 180 QCN sensors were installed following the M7.1 Darfield earthquake that occurred on September 3, 2010. Since the mainshock there have been hundreds of smaller, but damaging aftershocks as large as M6.3. The QCN network recorded events ranging from M2.6 – M6.3. 27 Feb 2012 | 1:08:59 UTC · Comment
