Hi All,  I would like to create a set of seismic sensor plans for school =
age kids, or adults.  I have built six sensors of different =
configurations.  I have found the best results, to be the horz. =
pendulum, using Chris's design as inspiration, but my version was and =
expensive project.
I have two simple, inexpensive verticals which work very well for me.  =
Both would lend themselves to someone with limited resources.

Is there anyone in the group who has a computer design program, like =
CAD? and would like to produce a nice set of isometric drawings, from =
these designs.   I have no program like that, and recorded my work in =
photos, sketches, and dimensions.  I think the finished plan, would be =
small enough to email or post and free for others who would like to =
build their first sensor.

It takes time and talent to produce a nice set of drawings, and I have =
seen some outstanding  work using today's drawing tools.   The two =
vertical designs I have are not perfect, but produce very good results.  =
If they could be shared with others it will only inspire them to build =
and use them, and eventually to make improvements.

Please email me if you would like to team up on such a project.
Thanks, Ted
