Hi, In mid august, Doug ( Doug) mentioned a project that was working on using a simm-sized micro controller that implements TCP/IP for a strong motion devices. Since then I have purchased two of these controller boards and the company that provides them are about to release an upgrade to the software the makes it easier to access I/O through the units programming language, Java. They have already released the documentation. Given easy access to the high speed hardware it would be simple to add some A/D chip. At the moment the device's supported I/O is a "one wire interface" and serial port. I'm looking forward to the upgrade and access to the "real" I/O. My vote is for Doug's concept for the strong motion device for the schools. Though the controller boards should have the better I/O software. Better I/O means a huge range of possibilities. The device could then be plugged into a local school network. All you need to do is give it a "IP" address. This coupled with a good 12 bit multi-channel A/D chip and support software would make an impressive interface. A/D chip -> LTC1290 ? The boards are cheap and powerful: see http://www.ibutton.com/TINI/ I'm not sure about the strong motion sensor, it all depends on what level of quake the schools want to record. Maybe the "MOUSE" on your computer is a strong motion device. It even tells you direction and intensity of the ground movement. Don't laugh.
