- don't think I should give you all the answers to the test... But, I guess
- a bit of help is in order. Look in the library at 1967 Scientific America.
- There you will find in one of the 12 months a gate device that is
- considered by many to be the GRAND DADDY of all home seismic projects. The
- device will fit your needs. A vertical device in England may not get the
- response that you need for a home project. You want a device that has a
- period of 8 to 30 seconds. Now once you have located it, you may want to
- look at it as a good place to start.
- For real help your helpers need a few more answers. What are you going to
- do once the coil puts out a single? Do you intend to capture some data to
- a system or run the output to a chart recorder? It also might help if you
- list what you have already found on the subject.
