I have obtained one of the onavi-B sensors to play with The quake sensor stanford is distributing is the onavi-A and onavi-B, shown here:
http://qcn.stanford.edu/sensor-performance?lang=en It uses a KXRB5 MEMS accelerometer from Kionix. My intent, originally, was to see if I could find a way to combine it with a ublox GPS over the internal i2c bus. It looks like that will require using a different ublox-6 chip than in the macx-1 with rewritable firmware and a firmware license, and... well... maybe going some other route like leveraging an arduino would be saner(?) At the moment however, I'm trying to figure out if there are any better MEMS sensors out there, or better ways to hook them up than this device which appears to have it's own protocol, running over serial... http://qcn.stanford.edu/join-qcn/request-a-sensor/sensor49-php The qcn.stanford.edu idea is pretty neat. it's designed for boinc after the fact analysis (and there is linux support) The USGS has got a fairly decent looking prototype of an early warning system, but their outside estimates for warning time is 20 seconds, presently, after what they've designed is fully deployed. (and they are 100m short on funding) http://blogs.laweekly.com/informer/2012/04/earthquake_warning_los_angeles_usgs.php -- Dave Täht SKYPE: davetaht http://ronsravings.blogspot.com/ _______________________________________________ Thumbgps-devel mailing list Thumbgps-devel@lists.bufferbloat.net https://lists.bufferbloat.net/listinfo/thumbgps-devel
