Hi all, Back again on the same subject, but only this time with alittle more teeth, as both items are available for those seeking to build their first seismometer sensors, or improve a existing sensor design/approach on their model/s. I acquired a number of coils from a E-Bay auction, and am willing to donate to those wishing to build seismometers. Once the pile runs out; thats all their is. The coils aren't professional grade material, but are a adoption to a commercially available four pole or two discrete magnets old computer assembly which I think is more than adequate as a major part of a overall sensor unit. Due to postage costs, I'am presently limiting mailings to those in the U.S.A. Check out this web site page at: http://www.geocities.com/meredithlamb/page064.html For those NOT interested in the coils, the magnets themselves are probably worth obtaining to check out with their own coils. Of course, thats my own opinion which isn't backed by a lab.. ....ha. Anyway....all this "might" save some time for the newbies and oldies, and perhaps even make for a successful amateur seismic operation where it might not occur at all. The web site also has references to other varieties of seismometers etc....just leave off the page064 stuff on the above address.
