hello PSN;

build the mechanics to any type of seismometer
then use several different sensors to see which
produces the best results ?

does anyone know what the best would be ??

variable optical, laser, led, etc..
variable capacitive, interleve plates ??
variable inductive ( like the old radio tuning slug in a coil )
velocity sensor ( magnet coil or magnet solinoid [coil plus iron core])
strain guage with a weight attached ? ( like bathroom scales )

are there mechanical ways to damp ( remove energy ) that might work
as well as magnetic ?

It might be nice to have a chord for a pendulum that will
damp as it flexes ???

is it possible to levitate two magnets against each other
then measure changes in the field as the two magnets
bounce south against south or vice-versa ?
hall effect or coil ?


it seems to me that whatever sensor you use you need two
identical for a proper input into a differential amplifier ??
that alone would increase your output by 6Dbv or X2 ?

Comments please ??
Please share your results unless you intend to capitalize
on what you have learned.

best regards to all;
