Sean Morrisey's professional design of an amateur teleseismograph Also see Keith Payea's version Both accessed 2010-9-29 Morrissey was a professional seismographic instrument engineer.  This superior design uses a zero-length spring to achieve a 60 second period, active feedback and a uniquely convenient variable reluctance differential transducer, with parts scavenged from a hardware store.  The frequency transform is carefully designed, unlike most amateur instruments.  Morrisey is deceased, but the site remains up as a public service.
