On my Lehman sensor I have been using a homemade coil that provided moderate output. I seem to have stumbled across something that works even better. From an old (dead) hard drive, I pulled the head positioning component and gave it a try. I drew up a (bad) picture of the piece I am talking about. It can be viewed at http://home.midmaine.com/~cgf/graphics/hd_sensor.jpg . I rigged up a linkage to the seismo and gave it a slow 1"/sec swing. I got an output of 0.026 V. the coil has a DC resistance of 18.1 Ohms. Anybody else tried a setup like this? -Travis __________________________________________________________ Public Seismic Network Mailing List (PSN-L)
