Several years ago there was a post on hackaday about a project of a home made raster tunneling microscope. I believe it used an isolation scheme built from several layers. A heavy plate (granite?) on 2 meter long springs, with some extra dampening hardware added, but also with half filled bycicle inner tubes. (Edit: Triggered my memory from a post below me). He had to make do with local situations (urban area?) but managed to get quite decent results. |

A large box of sand on partially inflated inner tubes is a popular isolation table design in the hologram community. It's cheap and much easier to move than a block of stone of similar mass (around 3000 kilograms for a 4' x 8' x 2' table). |

Over the years several intersing projects have been hacked together and posted via Hackaday. It may have someting you like. https://hackaday.com/?s=seismograph |

that yuma2 LTspice model is fun to play with |

It occurs to me that a survey volume of professional seismograph designs would be very interesting. Unfortunately, I cannot think of a single earthquake seismologist whom I know. A search with Amazon turned up nothing but reflection seismology books and SSA has no publications except the bulletin and research letters. Earthquake seismology and reflection seismology have almost no contact. I was a member of the Seismological Society of America for a number of years but dropped most of my professional society memberships when I retired as it costs quite a lot. And in my case I simply could not deal with managing 37 publications even if many of them were quarterly. I'm getting ready to do a major purge of journals from my library as I am running out of space. I already have far too many projects, but the SSA bulletin and Seismological Research Letters finally got scanned so members have electronic access. While I was a member they were just starting on making it available electronically. But had not yet scanned back volumes. The Society of Exploration Geophysicists which is the major reflection society routinely assembles important papers into review volumes on various topics. It's very convenient to have all the major papers in a single volume so you can read a citation just by flipping pages. If anyone reading this has a serious interest in seismograph design I'd like to urge joining SSA and collecting all the papers on seismograph design and testing into a review volume available through a book on demand service. I'd buy a copy in a heartbeat. Designing a new seismograph is now pretty rare. Most networks settle on an instrument and use that same instrument throughout the network. That greatly simplifies the process of calibrating the installation as you only have to model the earth coupling at that location. Getting an amateur station accepted into one of the official networks would be real badge of distinction. |
